NVIDIA Fermi with Snow Leopard in mind
The just-unveiled Fermi graphics architecture will find its way into Macs and play an important role in Mac OS X Snow Leopard, NVIDIA chief scientist Bill Dally said today. While it's expected that NVIDIA would continue to play an important part of future Macs, the researcher drew a particular connection between the new GPU design and Apple's new OS, expecting that it would provide a significant boost for those apps that implement OpenCL. Windows 7 will also get support through DirectX 11 and DirectCompute.

NVIDIA Fermi to start with three models
NVIDIA's Fermi architecture will start with three models if it ships before the end of the year as promised, one leak from Friday claims. A flagship single-chip model would have the 512 cores NVIDIA is advertising, but a second model would, like the GeForce GTX 295, have two slightly less powerful chipsets on one card that combined would be much faster. The slowdown may be necessary as Fudzilla believes the card would have a peak thermal power of 300W.

NVIDIA Fermi
NVIDIA this evening provided an early look at the next generation of its graphics processors. Nicknamed Fermi, the architecture for future GeForce, Quadro and Tesla chipsets will jump from 240 cores to a much larger 512 and should be much faster in each core courtesy of some industry-first techniques. Fermi chips will be the first GPUs to have a real cache hierarchy, with Level 1 caches to keep specific information on hand and a single, shared Level 2 cache for larger tasks; they will also have a new GigaThread engine that can transfer data in both directions at once and handle "thousands" of tasks at once.

ATI Radeon HD 5800 official
AMD's graphics label ATI tonight claimed to set a new benchmark for graphics with the Radeon HD 5800 series. The new video hardware is theoretically twice as fast as the 4870 and has an extremely large set of 1,600 stream (visual effect) cores -- enough to calculate 2.72 teraflops per second. Besides handling twice as many rendering tasks at once, the 5800 is also running a sixth-generation engine that shades and tessellates geometry more quickly, more GDDR5 memory bandwidth (150Gbps), and much improved techniques for antialiasing and anisotropic texture filtering.

ATI Radeon HD 5800 Leak
AMD's major video chipset update this fall has had its feature set and release date uncovered thanks to a slip of information Monday. The ATI Radeon HD 5800 series should be fronted by the 5850 and 5870, both high-end cards that could be the first to support Eyefinity, a technology that not unlike Matrox cards will support three displays on a single card. They are also to be AMD's first graphics cores to support DirectX 11 and OpenGL 3.1 visual effects in hardware.

Radeon HD 4200 Leak
AMD is developing an integrated graphics chipset for budget PCs that could take the performance crown in the category, a leaked roadmap shows. Codenamed RS880 but likely to be badged Radeon HD 4200 when it ships, the design will have a new graphics core that should run about 15 percent faster than "anything comparable" on the market, implying that NVIDIA's GeForce 9400 or 9400M may be the primary targets. The Inquirer adds that it should support AMD's Stream general-purpose computing technology and, by extension, would eventually support OpenCL.

NVIDIA Ion Sequel Speedup
The sequel to NVIDIA's Ion platform could be much faster than its predecessor when it ships, leaks today would show. While the current graphics and chipset combo is based on the GeForce 9400M and has just 16 visual effects cores, Fudzilla now hears that it will have 32 cores, potentially doubling the amount of simultaneous effects it can handle at once. The difference will have the most dramatic effect on 3D but could also impact general-purpose computing tasks that need CUDA or OpenCL.

AMD Demos DX11 GPU
AMD this morning said it has demonstrated the world's first graphics processor capable of supporting DirectX 11 and matching features in other software standards. The part is capable of tessellating polygons in real time, or breaking them down automatically into smaller shapes. Games and other apps that use the feature can have smoother details to characters or terrain without requiring as much processing power or that artists add all the information themselves.

Apple ARM Cortex Job
Apple has posted a job listing that hints at the company's future hardware direction for the iPhone, iPod touch and possible other devices. The position for a High Perform/Low Level Programmer asks for someone familiar not only for programming assembly-level code for ARM processors, which Apple already uses in its handhelds, but for the NEON vector math units used in the newer Cortex architecture for the mobile chips. Apple is especially concerned about experience with vector math and particularly values anyone with additional knowledge of vector units through general CPUs, such as Intel's SSE or the AltiVec units found on PowerPC G4 and G5 cores.

NVIDIA 2.2 released
NVIDIA has released version 2.2 of the CUDA toolkit and SDK. The new version of CUDA profiles C coded applications to use the computers GPU in addition to the CPU. This can enhance the computer's overall processing speed. The update also includes the ability to zero-copy, or to read and write directly from pinned system memory rather than send it through the graphics memory system. Using the technique requires either a GeForce 9300/9400 (or 9400M) integrated graphics core or else a GeForce GT 200 series board.

Mac mini NVIDIA Ion Rumor
Apple's Mac mini desktop will switch to NVIDIA's Ion platform and Intel's Atom chip as a result, an alleged confirmation by an NVIDIA partner asserts. The Cupertino company is believed to be using the combination graphics and system chipset in an updated computer that would also use the 1.6GHz, dual-core Atom 330. While slower in processing power than the existing Core 2 Duo, the mini system would have video performance close to if not exactly like the GeForce 9400M currently found in all aluminum MacBooks.

PowerVR SGX543 and iPhone
Imagination Technologies has quietly introduced a new PowerVR SGX chipset at CES that may point to the future of the iPhone and other graphics-intensive smartphones. The PowerVR SGX543 is the first to use a new platform which its creator estimates is much faster than older SGX and MBX chips. Its new, more vector-friendly graphics engine is about 40 percent faster than the previous SGX series in very effects-heavy graphics, the company claims, and is much faster in floating point math, geometry setup, and culling unneeded parts of the scene than the previous generation.

NVIDIA Candidate for Mac
Apple's rumored non-Intel mainboard platform may primarily involve a change of suppliers to NVIDIA rather than any kind of custom development, PCPer suggests. The enthusiast site notes that Santa Clara, California-based NVIDIA has been developing its first nForce mainboard chipset for Intel-based notebooks, currently codenamed MCP79, with the aim of improving several weaknesses that have affected Intel's own designs and thus Apple as well. The architecture would support all the necessary components for Intel's just-announced Core 2 processors, including a 1,066MHz system bus and the option of DDR3 memory.
