Rise of the Tomb Raider to Get DirectX 12 Eye Candy Soon?

Rise of Tomb Raider could be among the first AAA games that take advantage of DirectX 12, with developer Crystal Dynamics planning a massive update that adds a new renderer, and new content (VFX, geometry, textures). The latest version of the game features an ominously named "DX12.dll" library in its folder, and while it doesn't support DirectX 12 at the moment, a renderer selection has appeared in the game's launcher. DirectX 12 is currently only offered on Windows 10, with hardware support on NVIDIA "Kepler" and "Maxwell" GPUs, and on AMD Graphics CoreNext 1.1 and 1.2 GPUs.

AMD Working on Two "Polaris" GPUs: Raja Koduri

AMD Radeon Technologies Group (RTG) head Raja Koduri, in an interview with Venture Beat, confirmed that the company is currently working on two 14 nm FinFET GPUs based on the "Polaris" (4th generation Graphics CoreNext) architecture. He was quoted as referring to the two chips as "Polaris 10" and "Polaris 11." He remarked that the two chips are "extremely power efficient."

Koduri ran Venture Beat through what's new with these chips, besides being built on the 14 nm process and GCN 4.0 stream processors - a redesigned front-end, new geometry processors, a new multimedia engine, and new display controllers. GCN 4.0 lends the chip an up-to-date API support besides significantly higher performance, the new multimedia engine features native h.265 hardware acceleration, and the display controllers support the latest DisplayPort 1.3 and HDMI 2.0a connectors.

AMD "Polaris" Based Prototypes Sniffed Out at Logistics

Four prototype graphics cards based on GPUs that implement AMD's next-generation Graphics CoreNext architecture, codenamed "Polaris," were sniffed out, as they were making their way through air-cargo. At least two prototypes marked "C981" and "C980" made their way from Hong Kong, to Hyderabad, India, between late-December 2015 and early-January. It's speculated that the two could be SKUs based on the same chip.

Microsoft Could Refresh Xbox One Design with Polaris Based SoC

Microsoft could make the Xbox One "slimmer" and more energy-efficient by leveraging AMD's upcoming 4th generation Graphics CoreNext architecture, codenamed "Polaris." Found in the footnotes of AMD's "Polaris" press-deck, mentioned as an ominous-sounding "Xbox One Polaris," the mention hints at a revision of Xbox One that features an SoC running a "Polaris" based SoC. Microsoft could leverage the energy-efficiency improvements, and possibly upcoming processes, such as 14 nm FinFET, to bring down power-draw, thermal requirements, and possibly cost.

4th Generation Graphics CoreNext Architecture Codenamed "Polaris"

The fourth generation of AMD Graphics CoreNext GPU architecture has been reportedly codenamed "Polaris" by the company. It makes its debut later this year in the company's "Arctic Islands" GPUs, built on Samsung's 14 nm FinFET node. According to the company, Polaris will provide a "historic leap in performance/Watt" for Radeon GPUs. Chips based on Polaris will feature improvements to not just the compute units, but will also come with generational improvements to pretty much every other component, including a new front-end, display controllers, and a new memory controller supporting HBM2.

AMD debuted its first generation GCN architecture with the Radeon HD 7000 series, notably the "Tahiti" silicon. Its second-generation, GCN 2.0, (reported in the press as GCN 1.1), debuted with the R9 290 series, notably the "Hawaii" silicon. The third-generation, GCN 3.0 (reported in the press as GCN 1.2), debuted with the R9 285, notably the "Tonga" silicon; making "Polaris" the fourth-generation. GCN 4.0 will form the core micro-architecture of the "Arctic Islands" family of GPUs, which make their debut in mid-2016.

AMD Radeon HD 6000 and HD 5000 Series Relegated to "Legacy Support"

In a move that could affect scores of users of the still DirectX 11-compatible Radeon HD 6000 and HD 5000 series graphics cards; the company has reportedly decided to change their driver support model to legacy. This would entail "no additional driver releases" for these GPUs as they've "reached peak performance optimization as on November 24, 2015."

The last WHQL-signed driver that users of HD 6000 and HD 5000 series can use is Catalyst 15.7.1 WHQL; and those looking for a whiff of the new Radeon Software Crimson Edition, will be able to use a Radeon Software Crimson Edition Beta designed with legacy GPU support. The links to both drivers can be found in this page. With this AMD indicated that it will focus its driver development solely toward GPUs based on its Graphics CoreNext architecture (Radeon HD 7000 series and above).

Lack of Async Compute on Maxwell Makes AMD GCN Better Prepared for DirectX 12

It turns out that NVIDIA's "Maxwell" architecture has an Achilles' heel after all, which tilts the scales in favor of competing AMD Graphics CoreNext architecture, in being better prepared for DirectX 12. "Maxwell" lacks support for async compute, one of the three highlight features of Direct3D 12, even as the GeForce driver "exposes" the feature's presence to apps. This came to light when game developer Oxide Games alleged that it was pressured by NVIDIA's marketing department to remove certain features in its "Ashes of the Singularity" DirectX 12 benchmark.

Async Compute is a standardized API-level feature added to Direct3D by Microsoft, which allows an app to better exploit the number-crunching resources of a GPU, by breaking down its graphics rendering tasks. Since NVIDIA driver tells apps that "Maxwell" GPUs supports it, Oxide Games simply created its benchmark with async compute support, but when it attempted to use it on Maxwell, it was an "unmitigated disaster." During to course of its developer correspondence with NVIDIA to try and fix this issue, it learned that "Maxwell" doesn't really support async compute at the bare-metal level, and that NVIDIA driver bluffs its support to apps. NVIDIA instead started pressuring Oxide to remove parts of its code that use async compute altogether, it alleges.

Google Chooses Vulkan as the 3D Graphics API for Android

Google announced that it chose Vulkan, the next-generation, cross-platform 3D graphics API from Khronos, the people behind OpenGL; as the default API for upcoming versions of its Android operating-system. It currently uses OpenGL ES. GL-ES is widely supported across several embedded platforms, with its most recent update, GL ES 3.2, being released as recently as last week. What makes Khronos particularly interesting is that it's heavily based on AMD Mantle, a low-overhead API that proved its chops against DirectX 11 on the PC platform, before being withdrawn by AMD, in favor of DirectX 12.

Google will be helping developers through the transition between OpenGL ES and Vulkan using a suite of documentation, SDKs rich in compatibility test suits, and more. Vulkan's march to the PC could be a lot less straightforward. It's still being seen as rebranded Mantle, and while AMD announced support for all its Graphics CoreNext GPUs, there's no such announcement from NVIDIA. It could see good adoption with Apple's Mac OS, and desktop *nix. Vulkan could see a lot of popularity with game consoles other than Microsoft Xbox. Sony PlayStation 4, and Nintendo's upcoming console, which use AMD GCN GPUs, could take advantage of Vulkan, due to its lower CPU overhead and close-to-metal optimizations, compared to OpenGL.Source: Android Blog, Many Thanks to Okidna for the tip.

AMD Readies Radeon R7 370X to Counter GeForce GTX 950

AMD is reportedly giving final touches to the Radeon R7 370X, to preempt launch of NVIDIA GeForce GTX 950. The card will be based on the "Trinidad XT" silicon, and will max out components physically present on the chip. This means that the card will feature 1,280 Graphics CoreNext stream processors, 80 TMUs, 32 ROPs, and a 256-bit wide GDDR5 memory interface, holding 2 GB or 4 GB of memory. Leaked screenshots that disclose these specs suggest that AMD will carry over clock speeds from the R9 270X, working out to 1180 MHz core, and 5.60 GHz (GDDR5-effective) memory, working out to a memory bandwidth of 179.2 GB/s.

AMD Announces the A8-7670K Desktop APU

AMD announced availability of its newest budget socket FM2+ APU, the A8-7670K. This part, like the recently-launched A10-7870K, is based on the company's new 28 nm "Godavari" silicon. It combines a quad-core x86-64 CPU based on the "Excavator" micro-architecture, with an integrated Radeon R7 series graphics core, featuring six Graphics CoreNext 1.2 compute units amounting to 384 stream processors; a dual-channel DDR3 integrated memory controller, with native support for DDR3-2133 MHz memory; and a PCI-Express gen 3.0 root complex.

The CPU cores on the AMD A8-7670K are clocked at 3.60 GHz, with maximum TurboCore frequency of 3.90 GHz. The CPU features unlocked base-clock multipliers, enabling CPU overclocking. The four CPU cores are spread across two "Excavator" modules, with a total of 4 MB of cache between them. The GPU is clocked at 757 MHz, and offers native support for DirectX 12 (feature level 12_0). It offers Dual-Graphics support, letting you pair it with select discrete GPUs from AMD's lineup. With the advent of DirectX 12, it should also support asynchronous multi-GPU. The A8-7670K is available now, and is priced at US $117.99 in its retail package.

AMD "Fiji" Block Diagram Revealed, Runs Cool and Quiet

AMD's upcoming flagship GPU silicon, codenamed "Fiji," which is breaking ground on new technologies, such as HBM, memory-on-package, a specialized substrate layer that connects the GPU with it, called Interposer; features a hefty feature-set. More on the "Fiji" package and its memory implementation, in our older article. Its block diagram (manufacturer-drawn graphic showing the GPU's component hierarchy), reveals a scaling up, of the company's high-end GPU launches over the past few years.

"Fiji" retains the quad Shader Engine layout of "Hawaii," but packs 16 GCN Compute Units (CUs), per Shader Engine (compared to 11 CUs per engine on Hawaii). This works out to a stream processor count of 4,096. Fiji is expected to feature a newer version of the Graphics CoreNext architecture than "Hawaii." The TMU count is proportionately increased, to 256 (compared to 176 on "Hawaii"). AMD doesn't appear to have increased the ROP count, which is still at 64. The most significant change, however, is its 4096-bit HBM memory interface, compared to 512-bit GDDR5 on "Hawaii."

Radeon R9 390X Taken Apart, PCB Reveals a Complete Re-brand

People with access to an XFX Radeon R9 390X graphics card, took it apart to take a peek at its PCB. What they uncovered comes as no surprise - the underlying PCB is identical in design to AMD reference PCB for the Radeon R9 290X, down the location of every tiny SMT component. At best, the brands on the chokes and bigger conductive polymer caps differ; and 512 Gbit GDDR5 chips under the heatspreader, making up 8 GB of the standard memory amount. The GPU itself, codenamed "Grenada," looks identical to the "Hawaii" silicon which drove the R9 290 series. It's highly unlikely that it features updated Graphics CoreNext 1.2 stream processors, as older rumors suggested.

GFXBench Validation Confirms Stream Processor Count of Radeon Fury

Someone with access to an AMD Radeon Fury sample put it through the compute performance test of GFXBench, and submitted its score to the suite's online score database. Running on pre-launch drivers, the sample is read as simply "AMD Radeon Graphics Processor." Since a GPGPU app is aware of how many compute units (CUs) a GPU has (so it could schedule its parallel processing workloads accordingly), GFXBench was able to put out a plausible-sounding CU count of 64. Since Radeon Fury is based on Graphics CoreNext, and since each CU holds 64 stream processors, the stream processor count on the chip works out to be 4,096.

AMD Radeon Graphics Roadmap for 2015 Leaked

It looks like AMD's desktop discrete GPU lineup for 2015 will see a mix of rebrands, re-codename, and one big new chip, all making up the new Radeon R7 300 and R9 300 series. Cards based in this lineup should begin rolling out this month. Leaks from OEMs such as this one, suggest that the first of these should begin rolling out as early as June 16.

The spread is pretty cut and dry. "Hawaii," the chip driving the R9 290 series, will not only get a new codename as "Grenada," but also a seamless rebrand to the R9 390 series, with Grenada Pro making up the R9 390, and Grenada XT making up the R9 390X. One possibility could be AMD taking advantage of low 4 Gbit GDDR5 chip prices to cram 8 GB of standard memory amount, across Grenada's 512-bit wide memory interface. The R9 390X will compete with the GeForce GTX 970, while the R9 390 will offer an option in the vast price and performance gorge between the GTX 960 and GTX 970.

AMD "Fiji" HBM Implementation Detailed

Back in 2008, when it looked like NVIDIA owned the GPU market, and AMD seemed lagging behind on the performance and efficiency game, the company sprung a surprise. The company's RV770 silicon, the first GPU to implement GDDR5 memory, trounced NVIDIA's big and inefficient GeForce GTX 200 series, and threw AMD back in the game. GDDR5 helped the company double the memory bandwidth, with lower pin- and memory-chip counts, letting the company and its partners build graphics cards with fewer components, and earn great margins, which the company invested in development of its even better HD 5000 series, that pushed NVIDIA with its comical GeForce GTX 480, to hit its lowest ever in market-share. Could AMD be looking at a similar turnaround this summer?

Since the introduction of its Graphics CoreNext architecture in 2012, AMD has been rather laxed in its product development cycle. The company has come out with a new high-end silicon every 18-24 months, and adopted a strategy of cascading re-branding. The introduction of each new high-end silicon would relegate the existing high-end silicon to the performance segment re-branded, and the existing performance-segment silicon to mid-range, re-branded. While the company could lay out its upcoming Radeon R9 series much in the same way, with the introduction of essentially just one new silicon, "Fiji," it could just prove enough for the company. Much like RV770, "Fiji" is about to bring something that could prove to be a very big feature to the consumer graphics market, stacked high-bandwidth memory (HBM).

AMD Readies 14 nm FinFET GPUs in 2016

At its ongoing Investor Day presentation, AMD announced that will continue to make GPUs for every segment of the market. The company is planning to leverage improvements to its Graphics CoreNext architecture for the foreseeable future, but is betting on a huge performance/Watt increase with its 2016 GPUs. The secret sauce here will be the shift to 14 nm FinFET process. It's important to note here, that AMD refrained from mentioning "14 nm," but the mention of FinFET is a reliable giveaway. AMD is expecting a 2x (100%) gain in performance/Watt over its current generation of GPUs, with the shift.

AMD's future GPUs will focus on several market inflection points, such as the arrival of CPU-efficient graphics APIs such as DirectX 12 and Vulkan, Windows 10 pulling users from Windows 7, 4K Ultra HD displays getting more affordable (perhaps even mainstream), which it believes will help it sell enough GPUs to return to profitability. The company also announced an unnamed major design win, which will take shape in this quarter, and which will hit the markets in 2016.

AMD Radeon R9 380 Launched by PC OEM

Earlier this day, HP announced its newest line of desktop PCs, one of which comes with a curious-sounding Radeon R9 380 graphics card. HP's product pages for its new desktops aren't active, yet, leaving us to only speculate on what the R9 380 could be. One theory making rounds says that the R9 380 could either be a re-branded R9 285, or be based on its "Tonga" silicon, which physically features 2,048 stream processors based on Graphics CoreNext (GCN) 1.2 architecture, and a 384-bit wide GDDR5 memory interface. Another theory states that the R9 380 could be an OEM-only re-brand of the R9 280 or R9 280X, based on the 3+ year old "Tahiti" silicon.

The former theory sounds more plausible, because re-branding a "Tahiti" based product would be suicidal for AMD. Although based on GCN, "Tahiti" lacks a lot of architecture features introduced with "Hawaii" and "Tonga." AMD practically stopped optimizing games for "Tahiti," and some of its new features, such as FreeSync and XDMA CrossFire, can't be implemented on it. "Tonga," on the other hand, supports both these features, and one can create an SKU with all its 2,048 stream processors, and its full 384-bit GDDR5 memory interface unlocked. If the R9 380 is indeed an OEM-only product, then it's likely that the company's retail-channel products could be branded in the succeeding R9 400 series. GPU makers tend to re-brand and bump their SKUs by a series for OEMs to peddle in their "new" products at short notice.

AMD Cuts Prices of Radeon R9 285

As the Spring PC upgrade season heats up, AMD decided to woo mainstream gamers away from NVIDIA's GeForce GTX 960, by working with retailers in the EU to introduce price-cuts on its Radeon R9 285 graphics card. The card can now be had for under 180€ (incl taxes). The GTX 960, in comparison, starts at 192€ (incl taxes). The R9 285 offers higher performance than the GTX 960. It is, however, let down by higher power consumption and noise figures. Based on the 28 nm "Tonga" silicon, the R9 285 offers 1,792 stream processors based on AMD's Graphics CoreNext 1.2 architecture, 112 TMUs, 32 ROPs, and a 256-bit wide memory interface, holding 2 GB of memory.

AMD Readying "Godavari" APUs for May Launch, 14 nm APUs in 2016

AMD is readying its next-gen APUs, codenamed "Godavari" for launch in May 2015, according to industry sources in Taiwan. A successor to "Kaveri," Godavari will feature updated "Excavator" architecture based CPU cores, and the latest Graphics CoreNext 1.2 based stream processors on the integrated GPU. The APU will feature PCI-Express gen 3.0 and high-speed DDR3 integrated memory controllers, just like its predecessor "Kaveri," and could be based on the existing FM2+ platform. These chips will compete against some of the entry/mainstream variants of Intel's Core "Broadwell" processors. It's likely that these chips could be built on existing 28 nm process.

It's also being reported that AMD will launch its first APUs based on the 14 nanometer fab process, codenamed "Summit Ridge," in 2016. These will be succeeded by "Raven Ridge" APUs in 2017. AMD could use Samsung and GlobalFoundries to make its 14 nm chips. Lastly, AMD is reportedly in talks with ASMedia to integrate its USB 3.1 controller logic into its new motherboard chipset, which it plans to launch in September 2015.Source: DigiTimes

AMD Bets on DirectX 12 for Not Just GPUs, but Also its CPUs

In an industry presentation on why the company is excited about Microsoft's upcoming DirectX 12 API, AMD revealed its most important feature that could impact on not only its graphics business, but also potentially revive its CPU business among gamers. DirectX 12 will make its debut with Windows 10, Microsoft's next big operating system, which will be given away as a free upgrade for _all_ current Windows 8 and Windows 7 users. The OS will come with a usable Start menu, and could lure gamers who stood their ground on Windows 7.

In its presentation, AMD touched upon two key features of the DirectX 12, starting with its most important, Multi-threaded command buffer recording; and Asynchronous compute scheduling/execution. A command buffer is a list of tasks for the CPU to execute, when drawing a 3D scene. There are some elements of 3D graphics that are still better suited for serial processing, and no single SIMD unit from any GPU architecture has managed to gain performance throughput parity with a modern CPU core. DirectX 11 and its predecessors are still largely single-threaded on the CPU, in the way it schedules command buffer.

AMD R9 390 Series To Launch Alongside Computex 2015

AMD is preparing to time the launch of its next-generation Radeon R9 300 series with that of Computex 2015, in early June. The company had earlier planned to launch some products that are essentially price-adjusted rebrands of existing ones, such as the R9 380 series (being rebrands of R9 290 series on a slightly improved silicon), and the R9 370 series (being based on the "Tonga" silicon); but has decided to launch the two along with its flagship R9 390 series, based on a brand new silicon, around the same time. AMD's answer to the GTX TITAN-X from NVIDIA, the R9 390X will feature around 4,096 stream processors based on the Graphics CoreNext 1.3 architecture, and will implement an HBM (high-bandwidth memory) interface, with bandwidths in excess of 600 GB/s.

Sapphire Rolls Out Radeon R7 260X iCafe OC Graphics Card

Sapphire rolled out the entry-mid range Radeon R7 260X iCafe OC graphics card for casual-gaming PC builds (eg: low-cost Counter Strike gaming kiosks). Pictured below, the card looks rather premium, with its full-length, dual-slot cooler. That is, until you take a peek under its plastic shroud to find a cost-effective fan-heatsink cooling the GPU, with radially-projecting aluminium fins, a copper core base, and an 80 mm fan ventilating it.

The card draws power from a single 6-pin PCIe power connector; outputs include one each of dual-link DVI, HDMI 1.4a, and DisplayPort 1.2a. The card offers a factory-overclock of 1050 MHz core, and an untouched 5.00 GHz memory, against reference clocks of 1000 MHz on the core. Based on the 28 nm "Bonaire" silicon, the R7 260X offers 896 Graphics CoreNext stream processors, and a 128-bit wide GDDR5 memory interface, holding 2 GB of memory on this card. Expect a $100-ish pricing.

AMD to Launch New GPUs and APUs Only After March: CEO

In its an investor conference-call following its Q4-2014 and FY-2014 results, AMD stated that it will release new GPU and APU products starting Q2-2015, or only after March. "Going into the second quarter and the second half of the year with our new product launches, I think we feel very good about where we are positioned there," said Lisa Su, chief executive officer.

Q2-2015 will start off with the company's "Carrizo" line of all-in-one and notebook APUs. These chips will integrate the company's new "Excavator" CPU cores, with an integrated graphics core based on Graphics CoreNext 1.2 architecture (the same one AMD built its "Tonga" GPU on). Around the same time, AMD will launch new Opteron "Seattle" enterprise CPUs, which integrate up to eight ARM Cortex A-57 64-bit cores, targeting the ultra-dense server market. In Q2-2015, AMD will launch its latest Radeon Rx 300 series graphics processors. Its performance-segment part, the R9 380, will feature 4,096 GCN 1.2 cores, double that of its predecessor, and 4 GB of stacked HBM (high-bandwidth memory). Its mid-range chip, codenamed "Trinidad" will succeed "Curacao," and offer performance competitive to the $200-ish price-point.

AMD to Switch to GlobalFoundries' 28 nm SHP Node in 2015

Faced with continuous development roadblocks with TSMC, AMD is reportedly planning to switch to the 28 nm SHP process of GlobalFoundries, to build GPUs in 2015. The 28 nm SHP (super high-performance) node will allow the company to lower voltages, giving it greater room to increase clock speeds of its upcoming GPUs. AMD's GPUs in 2015 could be based on its latest Graphics CoreNext 1.2 architecture, and AMD needs every means to minimize voltages, and crank up clock speeds.

The company hasn't abandoned TSMC completely just yet, with reports speaking of AMD using the Taiwanese fab's 16 nm FinFet node to manufacture its next-generation "Zen" CPUs. Zen is the successor to AMD's "Bulldozer" architecture and its derivatives ("Piledriver" and "Steamroller.") It could feature a radically different core design.
