Mobile Fermi!

Wednesday, May 26th, 2010

nVidia just presented GeForce GTX 480M Fermi Mobile GPU. It’s more of a underclocked GeForce GTX 465 (to be presented soon), and will offer typically 50% of a GeForce GTX 480 desktop performance-level.

Still it’s largely over the last-generation GeForce GTX 285M that was just a GeForce 9800GTX in disguise, showing that GT200 GPU (GTX260..295) is just inadequate to be used on mobile platforms or downsized for middle-level gamer videocards!

The most interesting thing is not the gaming performance, and it will be impressive, on a par with my desktop GTX 260 or better, but Fermi being available on (huge) laptops. With real-world OpenCL & CUDA performance-level that is really impressive.

If you compare this laptop GPU to desktop CPU, for example with Folding@home distributed supercomputing projet, created for CPU and ported to GPU on nVidia’s CUDA and ATI’s brooke(n) technology you will have to compare with:

- 3 desktop Core i7 high-end CPU (or 6 laptop Core i7 Mobile CPU!)

- 2 Radeon 5870 desktop GPU (or a 5970 desktop GPU)

The raw numbers are more impressive on Radion HD 5xxx GPU, but the real-life OpenCL performance (and CUDA too) is almost unbeatable when you took CPU-developped programs ported to GPU!

And it’s a mobile GPU! I would like to see a PC card with it, to consume 2X less than my GTX 260 while offering better performance-level and Fermi computing ability :-)

ATI Radeon HD5870 Mobility: OpenCL Teraflop on a laptop

Friday, January 8th, 2010

The new ATI Radeon HD 5870 use the same 5xxx generation chip that offer full OpenCL 1.0 support, equivalent to nVidia’s GeForce 8xxx and later, but break the Teraflop MAD on a mobile GPU with 1120 Gigaflops!!!

Yes you read this well, you will be able to find laptops with 1 Teraflop raw power inside their GPU before spring, it will be at least 20X the processing power of the multi-core CPU of these laptops!

As a reminder, ASCI RED supercomputer broke the 1 Teraflop barrier in December 1996, with 4510 Pentium-Pro processors. Now you may do calculation at an equivalent pace with a laptop, only 13 years later! ouch!
