NVIDIA promises 'fastest DX11 GPU on the planet' very, very soon (video)
Nobody will be too shocked to hear NVIDIA expects its next flagship GPU to be the fastest that's ever been, but few will have guessed it'd also be one of the company's coolest and quietest. In the first public teasing of its next-gen graphics card (which is almost certain to bear the GeForce GTX 580 name tag), NVIDIA has revealed a new vapor chamber cooling system, which reminds us of Shuttle's ICE CPU cooler -- basically, water sealed within the chamber gets boiled by the hot elements (a copper plate in NVIDIA's case), which forces it to transfer heat away to the bits that are being cooled by the fan, where it chills out and recycles itself back to the boiling plate. The end result, according to NVIDIA, is about seven decibels less vroom relative to the GTX 480, along with lower operational temperatures. Besides that, the company's Tom Petersen also showed off an impressive tessellation demo and the first public display of Call of Duty: Black Ops gameplay, which was powered by this as yet unannounced GPU. Skip past the break to see it all on video. [Thanks, Vygantas]
NVIDIA unleashes GeForce GTX 480 and GTX 470 'tessellation monsters'
Let's get the hard data out of the way first: 480 CUDA cores, 700 MHz graphics and 1,401MHz processor clock speeds, plus 1.5GB of onboard GDDR5 memory running at 1,848MHz (for a 3.7GHz effective data rate). Those are the specs upon which Fermi is built, and those are the numbers that will seek to justify a $499 price tag and a spectacular 250W TDP. We attended a presentation by NVIDIA this afternoon, where the above GTX 480 and its lite version, the GTX 470, were detailed. The latter card will come with a humbler 1.2GB of memory plus 607MHz, 1,215MHz and 1,674MHz clocks, while dinging your wallet for $349 and straining your case's cooling with 215W of hotness. NVIDIA's first DirectX 11 parts are betting big on tessellation becoming the way games are rendered in the future, with the entire architecture being geared toward taking duties off the CPU and freeing up its cycles to deliver performance improvements elsewhere. This is perhaps no better evidenced than by the fact that both GTX models scored fewer 3DMarks than the Radeon HD 5870 and HD 5850 that they're competing against, but managed to deliver higher frame rates than their respective competitors in in-game benchmarks from NVIDIA. The final bit of major news here relates to SLI scaling, which is frankly remarkable. NVIDIA claims a consistent 90 percent performance improvement (over a single card) when running GTX 480s in tandem, which is as efficient as any multi-GPU setup we've yet seen. After the break you'll find a pair of tech demos and a roundup of the most cogent reviews.%Gallery-89115%
