AMD Radeon HD 7000 Series Won't Fully Support DirectX 11.2

Graphics processors based on first-generation Graphics CoreNext micro-architecture, slotted inside the "Southern Islands" and "Sea Islands" families, and branded under Radeon HD 7000 and Radeon HD 8000 (OEM) series, don't fully support Microsoft DirectX 11.2 API. Exclusive with the upcoming Windows 8.1 operating system, the Direct3D component of DirectX 11.2 introduces a handful of revolutionary consumer 3D features, such as "D3D tiled resources," which is analogous to OpenGL mega-textures; HLSL shader linking, frame-buffer scaling, etc.

In an interview with German publication c't Magazin, AMD engineer Laylah Mah pointed out that a feedback routine Microsoft deployed in the final specification of DirectX 11.2 turned out different from the one AMD anticipated. Mah stressed that the incompatibility is not at the level of the hardware, but the driver. The GPUs inside next-generation consoles like Microsoft Xbox One and Sony PlayStation 4 aren't fundamentally different from current AMD GPU micro-architecture, and at least one of the two, Xbox One, will leverage the latest DirectX.

AMD Redoing Radeon HD 7990 Under New Codename - "Malta"

AMD topped off its "Southern Islands" graphics card family with Radeon HD 7990 "New Zealand," although it didn't have a reference design board of the said SKU. Around October 2012, AIB partners PowerColor, VTX3D, and Club 3D each released their custom design Radeon HD 7990-branded graphics cards, which packed a duo of Radeon HD 7970 GPUs, a total of 6 GB of memory, making up for a dual-GPU solution. Among most of these, the GPUs were clocked in the neighborhood of 950 MHz, and memory at 5.50 GHz. ASUS joined the party much later with the ROG ARES II, with 1100 MHz core, 6.00 GHz memory, and liquid cooling, but commands a hefty $1,600. Post GTX Titan, ARES II remains, at least according to AMD, the single fastest graphics card. The company seems interested in standardizing a new set of specifications for HD 7990, which could be priced competitively against NVIDIA's GTX Titan and GTX 690.

Enter the new Radeon HD 7990 "Malta," a new codename, redone specifications (clock speeds), same dual-GPU graphics card, with [hopefully] a competitive price. Its development checks out with AMD's recent statement in its teleconference last month, where it stated that we could see "more HD 7990 action" this year. According to a Technic3D report, AMD is looking to replace the generally accepted 925/950/1350 MHz (core/PowerTune Boost/memory) clock speed standard of the HD 7990 with something over 1000 MHz, probably even 1050 MHz for the core. There is no word on memory clock speed changes, although with its 384-bit wide memory interfaces, we don't imagine the "Tahiti" GPU to be facing a dearth of memory bandwidth. The HD 7990 "Malta" like the HD 7990 "New Zealand," will lack an AMD reference design, so one could expect more custom-design cards by partners. The new SKU could launch some time before July.Source: Technic3D

AMD Adopts 28 nm Bulk Manufacturing in 2013

According to AMD senior VP and CTO Mark Papermaster, the company will adopt the 28 nanometer bulk CMOS silicon fabrication process for its chips in 2013. The bulk process is used to manufacture high-volume and less-complex products, such as motherboard chipset, entry-level APUs, etc. The company already takes advantage of TSMC 28 nm High-Performance process for highly-complex chip designs, such as its Southern Islands GPU family, and will continue using it for its next-generation "Sea Islands" GPUs. In related news, DigiTimes learned through sources that AMD's Sea Islands GPUs have entered tape-out stage, and are on course for a late-2012 volume manufacturing, and early-2013 launch schedule.

AMD Readies Trio of New Radeon HD 7900 Series SKUs

Apart from a few Radeon HD 7970 "X2" dual-GPU graphics cards, and a few non-reference design HD 7970, we didn't hear much about new Radeon SKUs, at Computex. AMD or its partners never even talked about the Radeon HD 7990. It appears now, that the company is working on three new SKUs that will likely replace existing ones, in a bid to replenish the competitiveness of its "Southern Islands" GPU family. The three new SKUs include the Radeon HD 7990, of which we've been hearing for a greater part of this year; the Radeon HD 7970 GHz Edition, which we knew was taking shape for some time now; and the new Radeon HD 7930.

Launch of the Radeon HD 7990 has been facing quite a few delays. We can't imagine technical hurdles with regard to board design, but the performance yield, and performance-per-Watt figures the SKU will have to produce, to ever make it to the market. The HD 7990 has the tough task of performing within an acceptable range of the GeForce GTX 690, on both these fronts.

New Details on ASUS ZEUS Emerge

A star attraction at the motherboard section of ASUS booth was its ZEUS Dual-GPU X79 concept motherboard. We got a chance to talk at lengths with people at ASUS about the exhibit, and learned a few details beyond what we already know. To begin with, ASUS is likely using a pair of "Southern Islands" family discrete mobile GPUs, not desktop ones. Further, it's likely that the GPUs are 28 nm "Pitcairn" based. The two GPUs are installed in CrossFire configuration. The next big detail is that the design focus on [evidently] isn't the integrated dual-GPU, but to demonstrate the first Thunderbolt-equipped X79 motherboard. The ZEUS has not one, but two Thunderbolt ports. The third (and most depressing) detail is that it's "highly unlikely" that the ZEUS will ever make it to the market. Think of it as yet another tradeshow concept by a big company. Perhaps ASUS doesn't want the ZEUS to end up like the ROG GSurf-365, its first off-beat ROG motherboard, which went beyond the show-floor but didn't have market-success.

Orbis Implements Multi-GPU, Too

Sony's next-generation PlayStation, reportedly codenamed "Orbis", is known to be powered by an AMD x86-64 CPU with graphics based on its Southern Islands architecture, from the older report. We're now hearing that Sony may implement a multi-GPU solution of its own. According to an IGN.com report, the CPU in question will be a custom-version of AMD's A8-3850 quad-core APU. This should serve as indication that the processor cores will be based on AMD's K10 Stars architecture, rather than K15 Bulldozer/Piledriver.

The GPU, on the other hand, will be based on the "Southern Islands" architecture, and the IGN.com report pin points it to resemble Radeon HD 7670. The HD 7670 is a re-branded HD 6670, which is based on the 40 nm "Turks" GPU. Turks uses neither Graphics CoreNext nor VLIW4, but the older VLIW5 number-crunching machinery. The most interesting piece of information here is talk of a multi-GPU configuration between this Turks-based GPU, and the GPU that's embedded into the "Llano" APU. We know that the graphics core embedded into AMD A8-3850, the Radeon HD 6550D, can work in tandem with Radeon HD 6670 to yield an AMD Hybrid CrossFireX configuration called "Radeon HD 6690D2". This could be end up being Sony's graphics weapon of choice.

Sony PlayStation 4 Codenamed "Orbis", Runs AMD x86-64 CPU, Southern Islands GPU

Sony may have codenamed PlayStation 4 "Orbis" (IPA: /ˈor.bis/), according to a Kotaku report. The next-generation game console is slated for "holiday season, 2013." This information was sourced by Kotaku, from a reliable source with a good track-record of accuracy. Orbis is derived from the Latin word for "circle", or "to circle/orbit". The term "Orbis Vita" or "Orbis Vitae" denotes "the circle of life." The specifications of Orbis known so far, include AMD-made x86-64 CPU, and an AMD-made GPU, built on the Southern Islands (Graphics CoreNext) architecture. In all probability, it could be a unified SoC, a highly scalar Fusion chip.

Tens of thousands people across the world are currently celebrating the Chinese new year as they welcome in the "Year of the Dragon" and Club 3D adds another bang with the introduction of the all brand new Club 3D Radeon HD 7950, followed by the earlier introduction of the Award Winning Radeon HD 7970, the world first 28nm GPU.

With 1792 stream processors, a 384 bit GDDR5 memory bus that provides 3.15 TFLOPs of computing performance, the Club 3D Radeon HD 7950 graphics cards are intended for gamers who never settle. Equipped with AMD Graphics Core Next Architecture and the latest power management technology, this card takes a no-compromise approach to gaming.

NVIDIA Taunts AMD's GCN Architecture Performance

As AMD's Radeon HD 7900 series is finding ground in the market, and NVIDIA's competitive product line still without a concrete launch schedule, the mind games have begun. In an interview to NordicHardware, a senior NVIDIA official said that NVIDIA expected more from AMD's new GPU family. "Honestly, we expected more from our competitor’s new architecture," the official said, indicating two interrelated things:
  • AMD's Southern Islands GPU family's performance levels are well within NVIDIA's expectations
  • NVIDIA's new architecture will be a lot more powerful than Southern Islands, because it was prepared keeping in mind a faster architecture from AMD than what Southern Islands ended up being
This latest comment could even release some pressure off NVIDIA to rush in a competitive product line.Source: NordicHardware

TechPowerUp GPU-Z 0.5.8 Released

TechPowerUp today released the latest version of GPU-Z, our popular video subsystem information and diagnostic utility that provides you with accurate information about the graphics hardware installed, and lets you monitor their clock speeds, fan speeds, voltages, VRAM consumption, etc., in real-time. Version 0.5.8 introduces two new features. The first one is a render test that applies sufficient load (not stress) on the GPU to pull it out of PCI-Express link-state power-management, to ensure the Bus information is accurate. If you find the PCI-Express bus link speed or PCIe version displayed incorrectly, simply click on the "?" button next to the field to launch the load test.

The next new feature is ASIC quality, designed for NVIDIA Fermi (GF10x and GF11x GPUs) and AMD Southern Islands (HD 7800 series and above), aimed at advanced users, hardware manufacturers, and the likes. We've found the ways in which AMD and NVIDIA segregate their freshly-made GPU ASICs based on the electrical leakages the chips produce (to increase yield by allotting them in different SKUs and performance bins), and we've found ways in which ASIC quality can be quantified and displayed. Find this feature in the context menu of GPU-Z. We're working on implementing this feature on older AMD Radeon GPUs.

More HD 7770 Leaks: Pictures, Plus 3DMark Benchmarks

Not quite two weeks ago, we reported on leaked pictures of AMD's upcoming Radeon HD 7770 mid-range graphics card based on the new Southern Islands architecture and listed its basic specs. Well, the leaks keep coming and bigpao007 of ChipHell has leaked more pictures with some benchmarks to go with them. The test setup consisted of an Ivy Bridge ES CPU – Core i5-3550K at 3.3Ghz and Z77 chipset-based motherboard. The driver used was the AMD Catalyst 8.940 RC2, giving the following 3DMark benchmark results:

Christmas Special: The PC Technology of 2011

Welcome to the TechPowerUp 2011 PC technology Christmas special. We hope that you will enjoy reading it while tucking into your turkey, Christmas presents and a little too much wine... In this article, we go through the technology of 2011 that has had the most significance, the most impact and was generally the most talked about. It's not necessarily the best tech of 2011 which is the most significant though, since lemons can be just as significant as the ground-breakers in how they fail to deliver - and the backlash that goes with it.

January: Intel Sandy Bridge i5 & i7

Released on January 9th, the new Intel Core i5 & i7 processors were based on Intel's second generation Core architecture built on a 32 nm production process (HEXUS review). They included an IGP (Integrated Graphics Processor) physically on the same piece of silicon along with HyperThreading. These new dual and quad core processors soundly beat all previous generations of Intel processors in terms of processing performance, heat, power use, features and left AMD in the dust. Therefore, Intel badly needed some competition from AMD and unless you have been living under a rock, you will know how that turned out in October with the launch of Bulldozer. Sandy Bridge was a sound win and is generally considered to be the only architecture worth considering at this point. The i5-2500K is currently at the sweet spot of price/performance. It comes at a stock speed of 3.3 GHz, but typically overclocks to an amazing 4.5 - 5 GHz with a decent air cooler and without too much difficulty in getting there. Models in the budget i3 range were released at various times later. See this Wikipedia article for details.

Radeon HD 7900 to Introduce Eyefinity 3D, HD 7970 European Pricing Surfaces

Reliable sources among AMD add-in board partners told DonanimHaber that the upcoming AMD Radeon HD 7900 series will introduce a new feature that other SKUs based on Southern Islands GPUs could also include. It's called Eyefinity 3D, and as the name might suggest, it's the next major update to Eyefinity, a technology that lets you span a single display head across up to six physical displays, and gives you the ability to use your available physical displays to accommodate multiple such display heads.

Eyefinity 3D adds support for 3D-optimized (120 Hz) displays, and lets you create large stereoscopic 3D display heads using a number of physical 3D displays. The technology behind this might not be as simple as it sounds, because the driver has to take into account the viewing angles of the displays in perspective to the user (as entered by the user), and calibrate the 3D image output. The same sources also hinted about the pricing of Radeon HD 7970.

AMD Radeon HD 7000 Series Single-GPU Graphics Card Price-Points Surface

AMD is on course to releasing its latest "Southern Islands" GPU family, and a fleet of desktop graphics card SKUs based on it, which will be led by a new high-performance GPU, codenamed "Tahiti", which will make up Radeon HD 7900 series; followed by performance GPU "Pitcairn", on which HD 7800 series will be based; "Thames" and "Lombok" making up the rest of the lineup. According to a report by DonanimHaber, HD 7970 (working name) is expected to be competitive with (or outperform) GeForce GTX 580, and priced at US $499. The HD 7950 will be competitive with (again, or outperform) GeForce GTX 570, being priced at US $399.

Things get interesting with Pitcairn, which is the successor of "Barts". This performance GPU is designed for sweet-spot SKUs, such as HD 7870 and HD 7850, which will be competitive with GeForce GTX 560 Ti / GTX 560, and priced at US $299 and $199, respectively. The Radeon HD 7670 will be particularly expensive, priced at US $179, followed by HD 7650 at $119. Further, it was reported that HD 7970 and HD 7950 will have a standard memory size of 3 GB.Source: DonanimHaber

Radeon HD 7000M Mobile GPUs Slated For December Launch Tabled

Around the 9th of December, AMD will announce its first Radeon HD 7000M series graphics processors, beginning with mobile parts (for notebooks). There will be at least 16 models announced, all based on two silicons: "Thames" and "Seymour", and being carved out of toggling various components within those GPUs. The models AMD will be launching will span across the Radeon HD 7400M series, 7500M series, and 7600M series. Thames and Seymour are brand new chips built on the 28 nanometer silicon fabrication process, which will allow AMD more TDP headroom, which it can use to step up clock speeds.

While we don't have key details such as stream processor, ROP, and TMU counts, a table based on data compiled by CompuBase.de lists out GPU and memory clock speeds, memory interface widths, and memory type. The table also mentions some higher-end GPU models named "Chelsea", "Heathrow", and "Wimbeldon". By now you know that all these codenames are after names of places in the UK. That's one way you can identify Radeon HD 7000M mobile GPUs from the "Southern Islands" Radeon HD 7000 desktop discrete GPU family (named after islands in the southern hemisphere).

Are Improving Integrated Graphics Slowly Killing Off Discrete Graphics Cards?

Intel started the trend of improving integrated graphics with their second generation LGA1155 socket Core i3, i5 & i7 line of processors. Depending on the model, these processors sport integrated HD2000 or HD3000 graphics right on the processor die, which nowadays give acceptable performance for low-end gaming and can play Full HD 1080p video perfectly. This trend is increasing with the upcoming Ivy Bridge processors, which will be able to support a massive 4096 x 4096 pixel display, as we reported here. AMD now also have equivalent products with their Llano-based A-series processors. So, where does this leave discrete graphics cards? Well, the low end market is certainly seeing reduced sales, as there really isn't enough of a performance difference nowadays to always warrant an upgrade from an IGP. As integrated graphics improve further, one can see how this will hurt sales of higher end graphics cards too. The problem is that the bulk of the profit comes not from the top-end powerhouse graphics cards, but from the low to mid-end cards which allow these companies to remain in business, so cannibalizing sales of these products to integrated graphics could make high-end graphics cards a much more niche product and crucially, much more expensive with to boot.

AMD Radeon HD 7000 Series to be PCI-Express 3.0 Compliant

AMD's next generation of graphics processors (GPUs) that will be branded under the HD 7000 series, are reported to be PCI-Express Generation 3 compliant. The desktop discrete graphics cards will feature PCI-Express 3.0 x16 bus interfaces, and will be fully backwards-compatible with older versions of the bus, including Gen 1 and Gen 2. Motherboards sold today feature Gen 2 PCI-E slots, although some of the very latest motherboards launched by major vendors feature PCI-Express 3.0 slots.

The new bus doubles the bandwidth over PCI-E 2.0, with 1 GB/s of bandwidth per lane, per direction. PCI-Express 3.0 x16 would have 32 GB/s (256 Gbps) of bandwidth at its disposal, 16 GB/s per direction. AMD's next generation of GPUs, codenamed "Southern Islands" will be built on the new 28 nm process at TSMC, and will upscale VLIW4 stream processors. Some of the first PC platforms to fully support PCI-Express 3.0 will be Intel's Sandy Bridge-E. Whether AMD's GPUs have hit a bandwidth bottleneck with PCI-E Gen 2, or is AMD trying to just be standards-compliant, is a different question altogether.Source: Donanim Haber

Foundry Delays to Push Back NVIDIA Kepler Launch to 2012

It looks like foundry issues are back to slow down the launch of NVIDIA's next generation high-end GPU, codenamed Kepler. The delay may push Kepler's launch to 2012, it was expected to launch by late 2011. The 28 nanometer silicon fabrication process at TSMC, a principal foundry partner of NVIDIA, is producing unsatisfactory yields. Add to that, Kepler's performance is lower than expected.

TSMC's 28 nm process at Fab 15 facility has already seen delays, which have even shaped AMD's designs in a big way. AMD had originally planned to design high-end VLIW4 chips on the 32 nm process at TSMC, but later decided to wait for the 28 nm process, leading to plans of 32 nm GPUs being scrapped by both GPU designers. TSMC was supposed to be in a position take orders of high-end 28 nm GPUs by Q4 2011, and was set to start pilot production for its 20nm process technology in the third quarter of 2012.

AMD Southern Islands GPU Codenames Surface

It was discovered that an early version Catalyst 11.7 contains entries for new GPUs, spelling out the possible codenames of upcoming AMD Southern Islands GPUs. Southern Islands is the next generation of AMD Radeon GPUs, which will possibly see propagation of VLIW4 SIMD design to GPUs in all market segments, and possible adoption of 28 nm manufacturing process. Moving on to codenames, 3D Center observes that the top of the line GPU is codenamed "Tahiti", there is a possibility of two single-GPU variants.

A graphics card that makes use of two Tahiti chips is codenamed "New Zealand". "Thames" is the codenamed of a possible low cost mobile chip, it could also be a performance chip. There's some uncertainty here. Not much is known about another chip codenamed "Lombok", either. Perhaps it's a performance desktop chip.Source: 3D Center
