AMD's Bristol Ridge APUs Released for the AM4 Platform in Retail Channels

AMD's AM4 socket really is shaping up to be one of the company's most versatile to date. From true quad-core CPUS (just now available through Ryzen 3's launch through to veritable svelte behemoths 8-core, 16-thread CPUs, AM4 has something for every consumer. AMD is now taking that show further with the release of the Bristol Ridge family of APUs, which includes eight APUs and three CPUs. While pricing wasn't announced at time of writing, the top-priced part should fall below the $110 mark and bottom out at $50, so as not to collide with AMD's Ryzen 3 1200 (although these products aren't specifically overlapping anyway.)

AMD's new entry-level processors will hit a maximum of 65 W TDP, with the top spot being taken by the 2-module, 4-threads A12-9800, running at 3.8 GHz base and 4.2 GHz Turbo. This part holds a Radeon R7 GPU with 512 Stream Processors (GCN 1.3, the same as in the Fury GPUs) running at 800 MHz Base and 1108 MHz Turbo. There are three 35 W parts (denoted by a capital E after the model name.) One thing users should take into account is that the Bristol Ridge APUs deliver a maximum of 8x PCIe 3.0 lanes - thus rendering a multi-GPU solution unfeasible.

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 Says "ZEN" CPU Architecture is Expected to Last 4 Years

After spending almost 4 years developing and perfecting (as much as can be perfected in such an amount of time) it's ZEN CPU architecture, AMD is looking to extract some mileage out of it. Mark Papermaster, AMD's chief technology officer, confirmed the four-year lifespan in a conversation with PC World at CES 2017 in Las Vegas, though he declined to discuss specifics. When asked how long ZEN would last (especially comparing to Intel's now-failing two-year tick-tock cadence, Papermaster confirmed the four-year lifespan: "We're not going tick-tock," he said. "ZEN is going to be tock, tock, tock."

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.

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).

AMD Details ZEN Microarchitecture IPC Gains

AMD Tuesday hosted a ZEN microarchitecture deep-dive presentation in the backdrop of Hot Chips, outlining its road to a massive 40 percent gain in IPC (translated roughly as per-core performance gains), over the current "Excavator" microarchitecture. The company credits the gains to three major changes with ZEN: better core engine, better cache system, and lower power. With ZEN, AMD pulled back from its "Bulldozer" approach to cores, in which two cores share certain number-crunching components to form "modules," and back to a self-sufficient core design.

Beyond cores, the next-level subunit of the ZEN architecture is the CPU-Complex (CCX), in which four cores share an 8 MB L3 cache. This isn't different from current Intel architectures, the cores share nothing beyond L3 cache, making them truly independent. What makes ZEN a better core, besides its independence from other cores, and additional integer pipelines; subtle upscaling in key ancillaries such as micro-Op dispatch, instruction schedulers; retire, load, and store queues; and a larger quad-issue FPU.

AMD Confirms Key "Summit Ridge" Specs

AMD CEO Lisa Su, speaking at the company's Computex reveal held up the most important CPU product for the company, the new eight-core "Summit Ridge" processor. A posterboy of the company's new "Zen" micro-architecture, "Summit Ridge" is an eight-core processor with SMT enabling 16 threads for the OS to deal with, a massive 40% IPC increase over the current "Excavator" architecture, and a new platform based around the AM4 socket.

The AM4 socket sees AMD completely relocate the core-logic (chipset) to the processor's die. Socket AM4 motherboards won't have any chipset on them. This also means that the processor has an integrated PCI-Express gen 3.0 root complex, besides the DDR4 integrated memory controller. With the chipset being completely integrated, connectivity such as USB and SATA will be routed out of the processor. The AM4 socket is shared with another kind of products, the "Bristol Ridge" APU, which features "Excavator" CPU cores and a 512-SP GCN 1.2 iGPU.

AMD Pro A12 "Carrizo" Chip Offers TDP as Low as 12W

AMD's "Excavator" module could fetch big power dividends for the company, with the top of the line Pro A12 "Carrizo" APU for mobile platforms offering TDP as low as 12W (normal usage), going up to 35W (maximum stress). AMD allows users to set the TDP for their processors. Built on the existing 28 nm process, these chips offer TDPs as low as the ones offered by Intel, built on 22 nm and even 14 nm nodes.

This is made possible because "Excavator" features heavily compacted registers and decode engines, and AMD spent a lot of R&D kicking out redundant or useless components from the silicon. The recently launched A-Series Pro "Carrizo" APUs feature two "Excavator" modules (four CPU cores), a GPU with eight GCN 1.2 compute units (512 stream processors), 2 MB of total cache, dual-channel DDR3-2133 integrated memory controllers.

AMD Zen Features Double the Per-core Number Crunching Machinery to Predecessor

AMD "Zen" CPU micro-architecture has a design focus on significantly increasing per-core performance, particularly per-core number-crunching performance, according to a 3DCenter.org report. It sees a near doubling of the number of decoder, ALU, and floating-point units per-core, compared to its predecessor. In essence, the a Zen core is AMD's idea of "what if a Steamroller module of two cores was just one big core, and supported SMT instead."

In the micro-architectures following "Bulldozer," which debuted with the company's first FX-series socket AM3+ processors, and running up to "Excavator," which will debut with the company's "Carrizo" APUs, AMD's approach to CPU cores involved modules, which packed two physical cores, with a combination of dedicated and shared resources between them. It was intended to take Intel's Core 2 idea of combining two cores into an indivisible unit further.

AMD Readies A10-7890K, A8-7690K and Athlon X4 880K Socket FM2+ Chips

AMD is planning to expand its socket FM2+ chip lineup with three new parts, the A10-7890K and A8-7690K APUs, and the Athlon X4 880K CPU. The three parts surfaced on the compatibility list of socket FM2+ motherboards by BIOSTAR. The architecture mentioned is "Kaveri," but the silicon could very well be "Godavari," (Kaveri refresh).

The refreshed lineup will be led by the A10-7890K, which features CPU clock speeds of 4.10 GHz out of the box, with an unknown TurboCore frequency (the current series leader A10-7870K offers 3.90 GHz with 4.10 GHz TurboCore). The A8-7690K offers CPU clocks of 3.70 GHz, and an unknown TurboCore frequency. There's no word on the iGPU clock speeds of the two chips. The third and most intriguing part is the Athlon X4 880K, with 4.00 GHz CPU clocks. The Athlon X4 FM2+ series lack integrated graphics, and make for good buys for people planning to build machines with discrete GPUs, on the FM2+ platform. All three chips offer unlocked base-clock multipliers, enabling CPU overclocking.
