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!
