Acer Introduces the Nitro 5 Gaming Laptop for Budget-minded Gamers

In a bid to increase options for budget-minded gamers, Acer has introduced the Nitro 5 gaming laptop, whose wealth of configurations start at a respectable $800. Choosing any kind of gaming-focused laptop over building your own desktop will always look like bad business, but how much one values mobility mays edge the decision towards one side or the other.

Specs-wise, it's a mix of respectable with the bare minimum: it features a 15.6-inch FHD IPS display, up to 32 GB of DDR4 2400 MHz memory, and is available in configurations featuring Intel's Core i5 or Core i7 processors paired with an NVIDIA GTX 1050 Ti graphics card, or your choice of an AMD 7th-gen A-series FX, A12 or A10 APUs, paired a Radeon RX550 GPU. Some models will include PCIe SSDs (up to 512GB) with up to 2TB of optional HDD storage. Ports include 1x Gigabit Ethernet, 1x USB 3.1 Type-C, 1x USB 3.0, 2x USB 2.0 ports, and 1x HDMI output. The Nitro 5 also supports 802.11ac Wi-Fi with a 2x2 MIMO antenna. The Nitro 5 will be available in North America starting July 1. Acer did not release detailed pricing, so there's no idea of what the $800 configuration will net you spec-wise (though an AMD and RX 550 are pretty much guaranteed). The Nitro 5 will also be available in the EMEA in August, starting at a much less interesting €1,139.

ASUS Teases Ryzen-based ROG Laptop

ASUS, through its ROG (Republic of Gamers)brand, has started teasing what is to be one of the first Ryzen-powered gaming laptops. Other than Ryzen's circular orange logo and the ROG brand, the video doesn't offer any specifics of what hardware rests under the hood. The clip includes the words "something has awakened," and the post is accompanied by the hashtag #Computex2017.

BIOSTAR Intros a Pair of AM4 Motherboards for Bitcoin Mining Rigs

BIOSTAR expanded its niche line of motherboards for Bitcoin-mining rigs, with two boards for the socket AM4 platform, the TA320-BTC, and the TB350-BTC. These boards feature a minimalist layout so you can drop in as many PCI-Express GPU or ASIC Bitcoin-mining cards as possible. As their names suggest, the TA320-BTC is based on the entry-level AMD A320 chipset, and the TB350-BTC the mid-range AMD B350. Both boards share an identical PCB, and barring for some chipset-level features, their feature-sets are largely identical.

The boards are built in the narrow ATX form-factor, and draw power from a combination of 24-pin ATX, 4-pin Molex (optional), and 8-pin EPS power connectors. A 6-phase VRM conditions power to the SoC, which is wired to two DDR4 DIMM slots, besides a PCI-Express 3.0 x16 slot, and six other PCI-Express 3.0 x1 slots. Storage options are limited to four SATA 6 Gb/s ports. Connectivity includes 6-channel HD audio, gigabit Ethernet, DVI and D-Sub display outputs, six 5 Gbps USB 3.0 ports, and two USB 2.0 high-power ports (1.5 A current). Both boards support Ryzen processors (up to 95W TDP), and 7th gen A-Series "Bristol Ridge" APUs. Available now, the TB350-BTC is priced at USD $84.99.

BIOSTAR Introduces A320 PRO Series of AM4 Motherboards

BIOSTAR is thrilled to present the latest addition to its AM4 product line-up with the debut of the 2nd-generation of the highly-acclaimed BIOSTAR PRO Series motherboards. The new BIOSTAR A320 PRO series features new and improved features that focus on reliability, stability whilst providing top-of-the-line performance. The 2nd-generation PRO Series motherboards featuring A320 chipset supports AMD RYZEN CPU and upcoming APUs for the AM4 socket. The board will support up to DDR4-2667 memory up to 32GB in capacity.

ID-Cooling Intros the SE-903-R CPU Cooler with AMD Ryzen Support

ID-Cooling introduced the SE-903-R tower-type CPU cooler with support for AMD socket AM4 processors, such as Ryzen and 7th gen. A-series "Bristol Ridge" APUs. The cooler is a variant of the SE-903, and comes with factory-fitted AM4 mounting clips and a red LED fan, compared to the blue LED the original SE-903 ships with. Its mounting clips easily hook on to the retention frames that come pre-installed on socket AM4 motherboards.

These aside, the SE-903-R is identical to the original. It is designed for thermal loads of up to 130W. It is a conventional tower-type heatsink featuring an aluminium fin stack, to which heat drawn directly from the base is fed by three 6 mm thick copper heat pipes, and ventilated by a 92 mm fan that spins up to 2,000 RPM, pushing 37.44 CFM of air, with a noise output of up to 23.1 dBA. The company didn't reveal pricing, although it shouldn't be too far off from the $20 price tag of the original.

AMD Talks Zen 3, "Raven Ridge," and More at Reddit AMA

AMD, at its post-Ryzen 7 launch Reddit AMA, disclosed some juicy details about its other upcoming socket AM4 chips, beginning with the rest of the Ryzen 5 and Ryzen 3 "Summit Ridge" processor roll-out, and a little bit about its 8th generation socket AM4 APU, codenamed "Raven Ridge." To begin with, AMD CEO Lisa Su stated that "Raven Ridge" will also be sold under the Ryzen brand. This would mark a departure from the less-than-stellar A-series branding for its performance APUs. "Raven Ridge" likely combines a "Zen" quad-core CPU complex (CCX) with an integrated GPU based on one of AMD's newer GPU architectures (either "Polaris" or "Vega").

The range-topping Ryzen 7 series will lead the company's lineup throughout Q1, with six-core and quad-core Ryzen 5 and Ryzen 3 series launches being scheduled for later this year. Our older reports pinned Ryzen 5 series rollout for Q2, and Ryzen 3 series for the second half of 2017. This is likely also when the company rolls out "Raven Ridge" initially as mobile Ryzen products (BGA packages, which will likely also be used in AIOs), and later as desktop socket AM4 parts.

AMD "Zen" Based APUs Later This Year

An AMD representative, responding to a Reddit question on AMD Ryzen branding, confirmed that the company will launch Mobile SoCs (APUs) based on the "Zen" micro-architecture later this year. The logical next-step for AMD with "Zen" beyond "Summit Ridge" has been to combine one or more quad-core "Zen" CCX (CPU complexes) with an integrated graphics core based on one of its newer GPU architectures ("Polaris" or "Vega").

The AMD representative confirmed that the company will launch mobile SoCs that combine "Zen" CPU cores with an integrated GPU, in the second half of 2017. This could hint at the availability of "Zen" powered notebooks, of all shapes and sizes by Holiday 2017. Over the year, AMD will begin launching "Zen" based products, starting off with 8-core high-end Ryzen 7 processors on March 2nd, six-core and some of the higher-end quad-core Ryzen 5 series processors in Q2-2017, and some of the lower-end quad-core Ryzen 3 parts in the second-half of 2017, now joined by mobile SoCs around the same time.

Biostar Intros the A6N-5100 "Kabini" Motherboard

Biostar introduced the A6N-5100 mini-ITX motherboard. A slight upgrade over the company's A6N-5000 from two years ago, the new board integrates AMD A4-5100 APU based on the "Kabini" silicon, which has the chops to outperform Intel's Celeron "Braswell" processors. The A4-5100 integrates a quad-core CPU ticking at 1.60 GHz, and AMD Radeon GCN graphics. The board features two DDR3 SO-DIMM slots, supporting up to 16 GB of memory, one PCI-Express 2.0 x16 slot, two USB 3.0 ports, HDMI display output, and storage connectivity that includes two SATA 6 Gb/s ports. The company didn't reveal pricing.

AMD Readies Ryzen Platform Drivers for Windows 7

AMD is reportedly providing platform (chipset) drivers for its upcoming socket AM4 platform, for the ageing Windows 7 operating system. This is noteworthy as rival Intel isn't providing Windows 7 drivers for its 200-series chipset, which drives the Core "Kaby Lake" processors, and the onboard graphics of Core "Kaby Lake" processors. Graphics drivers by AMD could power integrated graphics cores of the 7th generation A-series "Bristol Ridge" APUs, and the three socket AM4 chipsets - A320, B350, and X370.

AMD ZEN CPU Complexes Indivisible, Don't Expect 6-core Ryzen: Report

In what could be a blow to budget-conscious PC builders, reports are emerging that the quad-core CCX (CPU complex) units that make up Ryzen processors (and upcoming APUs that use them), are indivisible. This means that the "Summit Ridge" silicon can either be configured as full-fledged eight-core parts, or quad-core parts (one CCX) disabled. The likelihood of cost-effective 6-core parts seems slim.

AMD will continue to sell the Ryzen-branded "Summit Ridge" silicon in three grades - SR7 (top), SR5 (mid), and SR3 (entry-level), but the SR5 may not designate the previously rumored 6-core configuration. Instead, SR7 could indicate eight cores and SMT (multi-threading), which works out to 16 logical CPUs; SR5 could indicate eight cores minus SMT (eight cores, eight threads), and SR3 could designate quad-core with SMT (four cores, eight threads). SR7 and SR5 feature the full 16 MB of L3 cache, while SR3 features 8 MB. All three grades are "unlocked," in that they feature unlocked base-clock multipliers, making overclocking easy.

ASRock Socket AM4 Motherboard Lineup Detailed

At the 2017 International CES, ASRock showed off some of its first socket AM4 motherboards for AMD Ryzen processors and 7th generation A-Series "Bristol Ridge" APUs. Leading the pack is the X370 Taichi. Built in the ATX form-factor, the board draws power from a combination of 24-pin ATX and 8-pin EPS power connectors. It uses a 16-phase CPU VRM with high-capacity Super Alloy chokes. The AM4 socket is wired to four DDR4 DIMM slots, and two PCI-Expres 3.0 x16 slot (x8/x8 when both are populated). The third x16 slot is electrical x4 and wired to the chipset. Two other x1 slots make for the rest of its expansion area.

Connectivity on the X370 Taichi include two USB 3.1 ports (one type-A and one type-C), ten USB 3.0 ports, 8-channel PureSound 4 onboard audio solution (of the same grade the company is deploying on its high-end Intel Z270 motherboards), gigabit Ethernet with an Intel-made controller, and 802.11ac WLAN. Storage options include one 32 Gb/s M.2 slot, one 16 Gb/s M.2 slot, and eight SATA 6 Gb/s ports. Next up, is the X370 Professional Gaming. This board is practically identical to the X370 Taichi. The two boards share a common PCB, and differ only with the red+black color scheme on the X370 Professional Gaming, as opposed to white+black on the X370 Taichi.

Four GIGABYTE Socket AM4 Motherboards Pictured

GIGABYTE showed off four socket AM4 motherboards, designed for the upcoming AMD Ryzen processors and 7th gen. A-series APUs, at its 2017 CES booth. The lineup begins with the AB350M-D3H, an entry-level micro-ATX board based on the mid-tier B350 chipset; the mid-range AB350-Gaming 3, the mid-high segment AX370-Gaming K5, and the AX370-Gaming 5. The AB350-D3H covers the basics, with a 7-phase VRM, one PCI-Express 3.0 x16 slot wired to the AM4 socket, a second x16 slot that's electrical x4 and wired to the B350 chipset, one legacy PCI slot; one 32 Gb/s M.2 slot and six SATA 6 Gb/s ports (from which two are directly wired to the AM4 socket); and connectivity that includes 6-channel HD audio, gigabit Ethernet, two USB 3.1 (10 Gb/s) ports, DVI, HDMI 2.0, and DisplayPort.

Moving up the ladder, the AB350-Gaming 3 is a gaming-grade board in the ATX form-factor, featuring a red+black color scheme. The board draws power from a combination of 24-pin ATX and 8-pin EPS power connectors; conditioning it for the CPU with a 7-phase VRM. The APU is wired to four DDR4 DIMM slots, and one PCI-Express 3.0 x16 slot. Other expansion slots include two x16 slots that are electrical x4, and two x1 slots. Storage connectivity includes one 32 Gb/s M.2 and six SATA 6 Gb/s ports (from which two are low-latency ports). Display outputs include DVI, DisplayPort, and HDMI. USB connectivity includes two USB 3.1 (10 Gb/s) ports, and six USB 3.0 ports. GIGABYTE deployed its gaming-grade AMPUp! onboard audio solution with a 115 dBA SNR CODEC, ground-layer isolation, audio-grade capacitors, a headphones amp, and gold-plated audio jacks. Network is care of an Intel-made gigabit Ethernet controller.

MSI B350 Tomahawk Socket AM4 Motherboard Pictured

Here are some of the first pictures of MSI B350 Tomahawk, an upcoming socket AM4 motherboard that comes with support for AMD Ryzen CPUs. Positioned in the company's "Arsenal Gaming" series, this board is based on AMD's mid-tier B350 chipset. It covers the entire feature-set of the B350 chipset. The board draws power from a combination of 24-pin ATX and 8-pin EPS power connectors. It conditions it for the AM4 processor/APU with a 4+2 phase VRM. The AM4 socket is wired to four DDR4 DIMM slots, supporting up to 64 GB of dual-channel DDR4 memory, and one PCI-Express 3.0 x16 slot.

The second PCIe 3.0 x16 slot is electrical x4, and wired to the B350 chipset. Two each of legacy PCI and PCIe 3.0 x1 make for the rest of the expansion slots. Storage connectivity includes one 32 Gb/s M.2 slot, and four SATA 6 Gb/s ports. From these, two come directly from the APU/CPU. The board also offers up to eight USB 3.0 ports, gaming grade 8-channel HD audio (with ground-layer isolation and audio-grade capacitors); gigabit Ethernet, and display outputs that include HDMI, DVI, and D-Sub (which will be disabled when using Ryzen).

AMD A12-9800 "Bristol Ridge" AM4 APU with ASUS A320M-C Tested

German PC enthusiast "Crashtest" clinched a sweet combo of an AMD A12-9800 "Bristol Ridge" socket AM4 APU with an ASUS A320M-C entry-level micro-ATX motherboard, for 200€. Pairing it with 8 GB of dual-channel DDR4-2133 memory, the platform was put through the AIDA64 test-suite. In the memory front, the platform performs on-par with older platforms at comparable DDR3 bandwidth. The K15.6 integrated memory controller isn't producing the kind of memory bandwidth as the Core i7-6700K with dual-channel DDR4-2133 memory from AIDA64's internal reference bench table.

In the CPU-related tests, the APU has about the same performance as its predecessors, such as the A10-7850K. The chip features two "Excavator" x86-64 CPU modules, making up four cores, and is clocked at 4.20 GHz. There are performance upticks seen in tests such as Hash and VP8, where the chip likely benefits from new instruction sets.
More results follow.

GIGABYTE AX370-Gaming K3 Socket AM4 Motherboard PCB Pictured

The picture of a bare PCB of an upcoming GIGABYTE AX370-Gaming series socket AM4 motherboard is doing rounds on the web. The picture reveals the bare PCB of the motherboard with all its traces and printed markings, but at a stage before surface-mount components can be soldered onto it. One can still make out quite a bit about the board. AMD X370 is the company's upcoming high-end desktop chipset, which will be launched alongside the company's Ryzen 8-core processor, some time in February, 2017.

To begin with, the AX370-Gaming K3 is built in the ATX form-factor. Its AM4 socket supports both Ryzen "Summit Ridge" CPUs and 7th generation A-series "Bristol Ridge" APUs. The board draws power from 24-pin ATX and 8-pin EPS power connectors, and conditions it for the CPU with a 7-phase VRM. The AM4 socket is wired to four DDR4 DIMM slots. Expansion slots include one PCI-Express 3.0 x16, a second gen 3.0 x16 slot that's electrical x4, and three other gen 3.0 x1 slots. Storage connectivity appears to include at least eight SATA 6 Gb/s ports, and one 32 Gb/s M.2 slot. 8-channel HD audio, gigabit Ethernet, USB 3.1 (including type-C) ports, appear to make for the rest of the connectivity. GIGABYTE's signature Dual-UEFI is featured.
Many Thanks to TheLostSwede and Tomas H. for the tips!

AMD Socket AM4 "Bristol Ridge" APU De-lidded

Here are some of the first pictures of an AMD socket AM4 APU being de-lidded. De-lidding is the process of removing the IHS (integrated heatspreader), the metal plate covering the CPU die. Some PC enthusiasts remove the IHS to improve heat-transfer between the CPU and extreme cooling solutions, such as LN2/dry-ice evaporators. Overclocker Nam Dae Won, with access to a couple of socket AM4 chips (most likely 7th generation A-series "Bristol Ridge" APUs), de-lidded the chips, revealing a large rectangular die. AMD is using high-quality TIM between the die and the IHS, which could either be solder or liquid metal. There's also a clear picture of the underside pin-grid of the AM4 chip, which has a central cutout that lacks any SMT components. Socket AM4 has 1,331 pins.

AMD "Llano" Securities Fraud Lawsuit Ongoing; Class Action Status Granted

As you may remember, "Llano" was somewhat of a disappointment for AMD, to put it mildly. Production issues with partner Global Foundries meant that Llano's roll-out was affected and extended beyond its predicted time-frame. This, in conjunction with other various factors, such as lack of product appeal over disappointing performance and the usual competition from Intel, forced AMD to pull in its second-generation "Trinity" APU too soon. By the time production finally caught up, it ended up overproducing relative to diminishing demand, which resulted in unsold inventory, thus forcing an inventory write-down of "Llano" chips valued at around $100 million. This reduced the company's worth by nearly that much overnight, and tanked the value of the AMD stock. This, of course, didn't sit well with investors.

The as-of-yet ongoing securities fraud lawsuit over AMD's "Llano" APUs has just achieved a milestone, in having been authorized by the Court to proceed as a class action. The Court's decision doesn't imply that the defendants (Rory P. Read, Thomas J. Seifert, Richard A. Bergman, and Dr. Lisa T. Su) did anything wrong. The defendants have not been ordered to pay any money, no settlement has been reached, no money is available as of now and there is no guarantee that there will be in the future.

QNAP Partners with AMD On TVS-x73 NAS

QNAP Systems, Inc. have partnered with AMD, announcing the release and immediate availability (with pricing details yet to come) of the high-performance TVS-x73 NAS series. Packing an AMD Embedded RX-421BD quad-core APU (2.1 GHz base, 3.4 GHz boost), up to 64GB DDR4 RAM, AES-NI hardware encryption engine, two M.2 SATA 6Gb/s SSD slots capable of delivering up to 1,172 MB/s throughput (which can benefit from Qtier Technology to optimize storage efficiency across M.2 SSDs, SATA SSDs and HDDs), SSD cache, USB 3.1 (10Gbps), 10GbE expandability, dual HDMI output, and hardware-assisted 4K video decoding and encoding acceleration.

Built with a state-of-the-art metal design and topped off with a stylish gold finish, the business-class TVS-x73 series is available in 4 (TVS-473), 6 (TVS-673), and 8-bay (TVS-873) models, all of which support four Gigabit LAN. Two PCIe slots are available for greater system flexibility. One is pre-installed with a dual-port USB 3.1 Type-A card and the other allows for an optional QNAP dual-port 10GbE (10GBASE-T or SFP+) network card. The 10GbE-enabled TVS-x73 fully satisfies businesses that demand higher bandwidth for virtualization and fast backup and restoration for an ever-growing amount of data.

AMD Announces the 7th Generation AMD PRO Processors

AMD at the Canalys Channels Forum announced the first PCs featuring 7th Generation AMD PRO APUs (formerly codenamed "Bristol Ridge PRO"). Built for business, AMD PRO APUs deliver increased computing and graphics performance, improved energy efficiency, while providing a secure and stable platform to protect customers' IT investments.

"In the past two years we made incredible progresses in the commercial client segment. Since its inception in mid-2014, AMD PRO processor unit shipments increased more than 45 percent enabling businesses all over the world to simplify IT with secure, high performance, reliable solutions" said Jim Anderson, senior vice president and general manager, Computing and Graphics Business, AMD. "We are thrilled to have PC market leaders like HP and Lenovo expanding their use of AMD technology in their business client portfolios."

AMD Aggressively Clearing Inventory to Make Room for ZEN

AMD is reportedly "aggressively clearing" its inventories of current-generation processors, such products in the AM3+ and FM2+ packages; to make room for next-generation processors based on the "ZEN" architecture, and new 7th generation A-series "Bristol Ridge" APUs, both of which are built in the new socket AM4 package. You should be able to find AMD FX CPUs at attractive prices, so current 4-core and 6-core users could be lured to upgrade to faster 8-core chips, including those featuring the company's Wraith silent CPU cooler.

Taiwan industry observer DigiTimes reports that AMD will launch its next-generation "ZEN" processors, and motherboards based on the high-end X370 chipset, alongside the 2017 International CES expo, in early January. 2017 promises to be a big year for the company as it's not only attempting to regain competitiveness in the performance desktop CPU space, but also high-end graphics, with its Radeon "VEGA" family.

HP Socket AM4 A320 Chipset OEM Motherboard Pictured

Here is perhaps the first picture of a socket AM4 motherboard up close. The HP "Willow" is a micro-ATX motherboard custom-designed by the company to deploy on several of its upcoming desktop PC models, offered initially with AMD A-series "Bristol Ridge" socket AM4 APUs. Since this is custom-built for desktops that will probably be sold under $500, the board is built to a cost. The board features AMD A320 chipset.

The picture reveals socket AM4 to have extremely fine pins, and feature a square bolt-type cooler retention mechanism similar to that of contemporary Intel sockets. It does away with the rectangular layout. The advantage of a square layout is that it allows you to orient your cooler in any direction. Since the core-logic is moved to the APU/CPU package, the remaining rump of what AMD refers to as "chipset," is just a PCIe multi-function chip that puts out additional SATA and USB ports. With its TDP under 5W, this chip can make do without a heatsink. Other noteworthy features include two DDR4 DIMM slots, a PCIe gen 3.0 x16 slot, a short M.2 slot, a couple of SATA 6 Gb/s ports, and basic connectivity.

AMD "ZEN" Mobile Chips En Route Q2-2017 Launch

AMD will follow up its Q1-2017 launch of socket AM4 desktop processors and APUs based on the "ZEN" microarchitecture, with single-chip mobile processors and APUs in the following quarter, according to an Expreview report. These solutions could take advantage of the fact that "ZEN" CPUs and APUs completely integrate platform core-logic (chipsets), even though on the desktop platform, AMD is launching the A320, B350, and X370 chipsets to expand connectivity given out by the SoCs.

With requirements for fewer M.2, SATA, and USB 3.0 ports on mobile platforms such as notebooks, designs that completely do away with the chipset should theoretically be possible, and the company could use this to score design wins. Intel currently offers CPU and PCH on single packages, as multi-chip modules (MCMs).

AMD Unveils its 7th Generation A-Series Desktop APUs

AMD today unveiled its 7th generation A-series desktop APUs. Unlike its predecessors, the new chips are full-fledged SoCs, built in the new socket AM4 package, on which the company plans to launch its "Zen" processors. The 7th gen A-series APUs are based on the "Bristol Ridge" silicon, and are the first fully-integrated SoCs (systems-on-chip) from the company in the performance-desktop segment, in that the APU completely integrates the functionality of a motherboard chipset, including its FCH or southbridge.

This level of integration includes PCI-Express root-complex, USB 3.0, and storage interfaces such as SATA 6 Gb/s emerging directly from the AM4 socket. Some AM4 motherboards could still include a sort of "chipset," which expands connectivity options, such as USB 3.1 ports, additional SATA ports, and a few more downstream PCI-Express lanes. The amount of downstream connectivity and features decide the grade of the chipset. AMD is initially launching two chipsets, the A320 for the entry-level segment, and the B350 for mainstream desktops. The company plans to launch an even more feature-rich chipset at a later date (probably alongside ZEN "Summit Ridge" CPUs).

Vega Not Before 2017: AMD to Investors

In a leaked presentation meant for its investors, AMD states that it expects to launch the "Vega" GPU architecture no sooner than 2017. The company plans to get it out within the first half of 2017. What makes this decision significant is that the company isn't planning on making bigger GPUs on its existing "Polaris" architecture, and its biggest product is the $249 Radeon RX 480. This leaves the company's discrete GPU lineup virtually untended at key price-points above, against NVIDIA's GeForce GTX 1070, GTX 1080, and TITAN X Pascal, at least for the next five months.

In the mean time, AMD could launch additional mobile SKUs based on the Polaris 10 and Polaris 11 chips. The reasons behind this slow-crawl could be many - AMD could be turning its chip-design resources to the various semi-custom SoCs it's working on, for Microsoft and Sony, with their next-generation game consoles; AMD Vega development could also be running in-sync with market availability of HBM2 memory. 2017 promises to be a hectic year for AMD, with launch of not just Vega, but also its "ZEN" CPU architecture, the "Summit Ridge" processor, and APUs based on the CPU micro-architecture.

AMD ZEN Quad-Core Subunit Named CPU-Complex (CCX)

We've been chasing AMD Zen for a long time now. Our older report from April 2015 uncovered an important detail about component organization on Zen processors - the clumping of four CPU cores into a highly-specialized, possibly indivisible subunit referred to then, as the "Zen Quad-core Unit." Some of the latest presentations about the architecture, following AMD's "performance reveal" event from earlier this month, shed more light on this quad-core unit.

AMD is referring to the Zen quad-core unit as the CPU-Complex (CCX). Each CCX is a combination of four independent CPU cores. Unlike on "Bulldozer," a "Zen" core does not share any of its number-crunching machinery with neighboring cores. Each "Zen" core has a dedicated L2 cache of 512 KB, and four Zen cores share an 8 MB L3 cache. AMD will control core-counts by controlling CCX units. A "Summit Ridge" socket AM4 processor features two CCX units (making up eight cores in all), sharing a dual-channel DDR4 memory controller, and the platform core-logic (chipset), complete with an integrated PCI-Express root complex. Socket AM4 APUs will feature one CCX unit, and an integrated GPU in place of the second CCX. With this, AMD is able to bring the two diverse desktop platforms under one socket.
