Nvidia on Tuesday introduced laptop technology that switches between integrated graphics and a graphics card, depending on application requirements, to extend battery life.
Called Optimus, the technology makes the switch seamlessly, using an Nvidia discrete graphics card for 3-D games, video, or other graphics-intensive applications; and, for more mundane computing tasks such as e-mail and Web browsing, running the far less power-hungry graphics chip integrated into the chipset that runs with the CPU.
Now it is official. The first two consumer level GPUs that are based on the GF100 are going to be called Geforce GTX 480 and Geforce GTX 470. This has been announced on Nvidia's Facebook site. Although the final specifications of the GF100 have not been released yet, there is quite some material available, since Nvidia showed systems at the CES where they also presented the tech demos of the GF100.
Rambus has scored a victory in its protracted legal battle with Nvidia. The US International Trade Commission ruled against Nvidia, declaring Rambus' patents valid and concluding Nvidia infringed three Rambus patents.
The patents were used in Nvidia's memory controllers, which were coupled with Nvidia GPUs and other processors.
Nvidia’s latest Geforce drivers, now in version 196.21, might bring SLI and multi-GPU support to certain games but it seems to have brought another, somewhat unexpected gift from the company – disabled overclocking.
So, overclocking software such as RivaTuner V2.24C, EVGA Precision V1.9.0 and similar all had trouble in handling core, shader or memory clocks during overclocking.
Nvidia says that this is a bug that will be resolved in a timely fashion, but until then we’d advise overclockers to steer clear of the “new and improved” driver.
Nvidia has confirmed that its Fermi-based GF100 GPU will feature 512 CUDA processors, 16 geometry units, 384-bit GDDR5 memory bus and 48 ROP engines.
According to ZDNet's Adrian Kingsley-Hughes, the GF100 is also expected to include 4 raster units, 64 texture units and DirectX 11 support.
"Each GPU is made up of four separate GPC (Graphics Processing Clusters).
Nvidia finally confirmed, they will offer GF100 sneak peek at CES 2010. But keep in your mind, launch date is still same and probably we can not buy any new DX11 GeForce graphic cards before March.
Here are some highlights about GF100;
- 512 CUDA Cores
- SLI, 3D Vision, CUDA, Physx and other Nvidia techs
- 32x brand new AA mode
- Full 3D Blu-ray decoding
- Hardware based over voltagging.
- And according to Nvidia, fastest GPU!
It seems like the latest FTC lawsuit against Intel could spell many a great thing for Nvidia, and not just make them rediscover their artistic spirit. In a lawsuit filed on Wednesday, FTC proposed a few dodgy points, most notable being number 17 and 18.
Number 17 states: "Requiring Intel to make available technology (including whatever is necessary to interoperate with Intel’s CPUs or chipsets) to others, via licensing or other means, upon such terms and conditions as the Commission may order, including but not limited to extensions of terms of current licenses."
Nvidia brushed off the technology lead that rival Advanced Micro Devices built by releasing the first graphics chips to support DirectX 11, saying the release only gives AMD a short-term advantage that won't have a long-term effect on the graphics market.
A week and a half ago, news hit the internet that Nvidia had launched its first Geforce 300-series desktop card, which garnered hopes from its massive consumer base that it was preparing to unveil the full next-generation series over the next few months. Unfortunately, the unveiling of the “behemoth” Geforce G 310 was overhyped too quickly, as prospective consumers and media analysts alike soon realized it to be a simple rebranded, refreshed version of the Geforce G 210 marketed for OEM distributors.
