1 TFLOP GPU
TechRadar points out that the University of Reading just installed a new room-sized high density 20 TeraFLOPS computing and compares this to NVIDIA's new GPU that will be released this summer. This chip is rumoured to have a raw computing power of 1 TFLOPS and Tech Radar believes a four-way GPU node could deliver the same computing power as the new Reading University supercomputer:
On paper, it's extremely plausible. In terms of raw parallel compute power, 3D chips put CPUs to shame. A good recent example is the new room-sized, high density computing cluster installed by Reading University.Elemental HD - superfast video encoding
Designed to tackle the impossibly complex task of climate modelling, it weighs in at no less than 20 TeraFlops. That sounds impressive until you realise that just a single example of Nvidia's next big GPU, due this summer, could deliver as much 1TFlop. So, a few four-way Nvidia GPU nodes will soon offer the same raw compute power as a supercomputer built using scores of CPU-based racks.
One of the first major applications of NVIDIA's CUDA technology for consumers will be video encoding. The GPU maker is developing a video encoding application known as Elemental HD and says a GeForce 8800 graphics card will be able to downsize a typical HD movie for an iPod in just over 20 minutes. That may sound long but a decent dual-core Intel processors may need up to eight hours of more to finish this job!
Downsizing a typical HD movie for an iPod using a conventional PC processor can take up to eight hours or more, even with a decent dual-core Intel chip. Nvidia says the same job can be done in just over 20 minutes on an 8800 series Nvidia graphics board.Besides video processing NVIDIA is also working on a CUDA version of AGEIA's PhysX processor. A software download that will add PhysX support to GeForce 8 and 9 series graphics cards is expected this Summer.
"When you look at the question of whether you should transcode video on a GPU or CPU, when you consider it in performance-per-buck terms, it's currently obscenely the wrong way round," Taylor says. And the solution is simple enough. Don't spend any more money overall. Just spend a little less money on your Intel CPU and a little more on your Nvidia GPU.
