Yesterday, AMD unveiled its surprise for this year's Computex, with a demonstration of a DirectX 11 3D scene. Behind the scenes though, was what AMD claimed to be the "world's first true DirectX 11 graphics processor". The hardware itself however, wasn't publicly displayed, although a memento of AMD's partnership with TSMC, a wafer of 40 nm DirectX 11 GPUs, was made public. VR-Zone however, sneaked into the backdrops and pictured the machine that ran the demo (which ironically, was built into a case with a side-window).

The graphics card, a portion of which, is hidden behind the "wing" of the AMD Dragon logo graphic, is seen to be about 8.5 inches long, spans across two slots, and has a seemingly sporty cooler with the ATI-red shroud. It draws power from a single 6-pin PCI-E connector. The photographers note that this could be the RV840-based desktop accelerator, which forms the performance-mainstream product for the company's upcoming DirectX 11-compliant GPU lineup codenamed "Evergreen". The first product from this series is expected to be released in September, weeks ahead of the launch of Microsoft Windows 7.

At a press conference in Taipei, Taiwan today, AMD publicly demonstrated the world's first Microsoft DirectX 11 graphics processor. The series of demonstrations shed new light on the significantly improved computing experience set to debut at the end of 2009. The fusion of AMD's new ground-breaking graphics processors with the forthcoming DirectX 11 programming interface is set to forever change both applications and PC gaming for the better. To illustrate, AMD showed numerous examples of faster application performance and new game features using the world's first true DirectX 11 graphics processor.

NVIDIA's upcoming next-generation graphics processor, codenamed GT300 is on course for launch later this year. Its development seems to have crossed an important milestone, with news emerging that the company has already taped out some of the first engineering samples of the GPU, under the A1 batch. The development of the GPU is significant since it is the first high-end GPU to be designed on the 40 nm silicon process. Both NVIDIA and AMD however, are facing issues with the 40 nm manufacturing node of TSMC, the principal foundry-partner for the two. Due to this reason, the chip might be built by another foundry partner (yet to be known) the two are reaching out to. UMC could be a possibility, as it has recently announced its 40 nm node that is ready for "real, high-performance" designs.

The GT300 comes in three basic forms, which perhaps are differentiated by batch quality processing: G300 (that make it to consumer graphics, GeForce series), GT300 (that make it to high-performance computing products, Tesla series), and G200GL (that make it to professional/enterprise graphics, Quadro series). From what we know so far, the core features 512 shader processors, a revamped data processing model in the form of MIMD, and will feature a 512-bit wide GDDR5 memory interface to churn out around 256 GB/s of memory bandwidth. The GPU is compliant with DirectX 11, which makes its entry with Microsoft Windows 7 later this year, and can be found in release candidate versions of the OS already.

A real monster seems to be taking shape at NVIDIA. The company's next big graphics processor looks like a leap ahead of anything current-generation, the way G80 was when it released. It is already learned that the GPU will use a new MIMD (multiple instructions multiple data) mechanism for its highly parallel computing, which will be physically handled by not 384, but 512 shader processors. The count is a 112.5% increase over that of the existing GT200, which has 240.

NVIDIA has reportedly upped the SP count per cluster to 32, against 24 for the current architecture, and a cluster count of 16 (16 x 32 = 512). Also in place, will be 8 texture memory units (TMUs) per cluster, so 128 in all. What exactly makes the GT300 a leap is not only the fact that there is a serious increase in parallelism, but also an elementary change in the way a shader processor handles data and instructions, in theory, a more efficient way of doing it with MIMD. The new GPU will be DirectX 11 compliant, and be built on the 40 nm manufacturing process. We are yet to learn more about its memory subsystem. The GPU is expected to be released in Q4 2009.

Never in recent times have we seen NVIDIA and ATI locked in such fierce market competition. The two are seen exchanging blows with product launches and price-cuts. ATI looks to be in the mood to take this competition to the next-level: DirectX 11 compliant GPUs. Microsoft has already released DirectX 11 with the pre-release versions of Windows 7 operating system. A recent report by Heise Online indicates that AMD will be ready with an ATI RV870, the company's first DirectX 11 GPU by the end of July, or early August.

Another source, The Inquirer, states NVIDIA's GT300 GPU launch for October. If you were to count these claims, AMD is put two to three months ahead of NVIDIA when it comes to time-to-market introduction of a new GPU generation. Now, whether you have DirectX 11 compliant software that makes use of the new technology available that soon is a different thing altogether. This will determine the practicality of a DirectX 11 GPU in July/August.

Being on the forefront of technology adoption as far as its graphics products go, AMD will have a notebook platform with DirectX 11 compliant integrated GPUs ready by 2011, reveal company slides sourced by Expreview. The iGPU will be part of the company's "Accelerated Processing Unit" (APU) design approach to the PC's central processing. The APU draws parallels with Intel's upcoming processor designs where the CPU package holds both the CPU and northbridge dice in a multichip-module. One of the first AMD APUs, codenamed "Llano" will be part of the company's "Sabine" mobile platform. Typically consisting of the CPU, a DDR3 memory controller, a northbridge with integrated graphics processor, and the PCI-Express root complex, APU eliminates discrete northbridge from board design.

Slated for 2011, the Llano APU comes out at a time when DirectX 11 is expected to be an established API. The iGPU will also pack UVD 3.0, a next generation hardware-accelerated video decoder by AMD. It will be built on the 32 nm manufacturing process by AMD's foundry partner(s). It features up to 4 x86 processing cores, an iGPU, a memory controller supporting DDR3-1600 memory, 128-bit floating-point execution units (present even with current generation Phenom processors), and a BGA design with a low-TDP package. Llano will be accompanied by the SB9xxM series southbridge. This chip would make for most of the board's nucleated machinery apart from the APU. It will integrate the "DAC" (we interpret audio DAC), USB 3.0 hubs with 16 ports, a 6-port SATA controller, and clock-generator.

Every once in a while, comes a GPU by NVIDIA that marks the evolution of GPU architecture for NVIDIA. A good example of this would be the G80, which was a distinct evolution of the GPU architecture for the company. Sources tell Hardware-Infos that the GT300 is on course of being one such GPU that comes with distinct architectural changes. To begin with, GT300 will start the company's DirectX 11 conquest the way its ancestor, the G80 did for DirectX 10, which turned out to be largely a successful one.

The GT300's architecture will be based on a new form of number-crunching machinery. While today's NVIDIA GPUs feature a SIMD (single instruction multiple data) computation mechanism, the GT300 will introduce the GPU to MIMD (multiple instructions multiple data) mechanism. This is expected to boost the computational efficiency of the GPU many-fold. The ALU cluster organization will be dynamic, pooled, and driven by a crossbar switch. Once again, NVIDIA gets to drop clock-speeds and power consumptions, while achieving greater levels of performance than current-generation GPUs. With GT300, NVIDIA will introduce the next major update to CUDA. With the new GPUs being built on the 40nm silicon fabrication process, transistor counts are expected to spiral-up. NVIDIA's GT300 is expected to go to office in Q4 2009, with its launch schedule more or less dependent on that of Microsoft's Windows 7 operating system that brings in DirectX 11 support.

Microsoft's Ben Basaric, product marketing manager for Windows products, confirmed to PC Games Hardware that the next major update to the DirectX API, DirectX 11 would accompany Windows 7, the next major consumer operating system software by Microsoft. This, overwriting his own statement given to the website earlier that he wasn't sure if DirectX 11 would be ready to ship with the OS upon its launch. Furthermore, he also indicated that Windows Vista will have access to the updated API, although not sure at what point in time.

The year 2008 so far, has been very eventful for the graphics card market. A reinvigorated GPU lineup by ATI, brought in some fierce competition to NVIDIA, which resulted in a tug-of-war with pricing graphics cards in the market, with either company refusing to lose on grounds of pricing. This event, coupled with the announcement of several game titles by game publishers, resulted in bumper-sales of graphics cards, giving the present state of the global economy little or no relevance.

The months to come hold the same amount of importance for both AMD and NVIDIA, where the next round of competition begins with successors to current high-end products being slated. NVIDIA is expected to continue with its monolithic high transistor-count GPU design methodology, while AMD could bring in a little change to the way it uses two efficient GPUs to build powerful products.

AMD conducted a presentation at CEATEC Japan, where the company took a sneak-peak at how the role of GPUs would become critical to the PC of tomorrow. This of course revolved around the company's newly adopted "The Future is Fusion" slogan, integrating all of AMD's technological expertise into object and function oriented solutions for the PC industry.

Among the numerous slides that formed part of the presentation, one such slide, shows some very interesting points on what the year 2009 looks like, from AMD's perspective. It shows a lot of things slated for much later to make it to the industry. To begin with, the DirectX 11 API and Windows 7 (Vienna) operating system could make it to the industry in 2009. However, there's no mention of them being "released" as such, or if they could just be working prototypes, such as alpha releases for use by select parts of the industry for mutual technology development.

Microsoft has released a handful of details about DirectX 11, the latest version of the company's API.

• Full support (including all DX11 hardware features) on Windows Vista as well as future versions of Windows
• Compatibility with DirectX 10 and 10.1 hardware, as well as support for new DirectX 11 hardware
• New compute shader technology that lays the groundwork for the GPU to be used for more than just 3D graphics, so that developers can take advantage of the graphics card as a parallel processor
• Multi-threaded resource handling that will allow games to better take advantage of multi-core machines
• Support for tessellation, which blurs the line between super high quality pre-rendered scenes and scenes rendered in real-time, allowing game developers to refine models to be smoother and more attractive when seen up close
