NVIDIA cuts down specification of Fermi chips for Tesla cards

December 27th, 2009 Leave a comment Go to comments

EliteBastards – Although we won’t be seeing products based on “Fermi” (aka GF100) until a few months into 2010, NVIDIA have already announced their first Tesla-based offerings that will be using this architecture.  However, what we weren’t expecting to see was for these parts to be using a cut-down version of GF100 with fewer Stream Processors – is this a sign of further issues for NVIDIA’s latest and greatest architecture, or simply a design decision for these particular parts?

As reported previously, NVIDIA Tesla C2050 and C2070 computing processor boards are single-chip cards with 3GB and 6GB (respectively) of on-board GDDR5 memory (with ECC enabled, user available memory will be 2.625GB for a C2050 and to 5.25GB for a C2070) with 384-bit interface operating in the range between 1.80GHz and 2.0GHz. The cards are mostly designed for desktop-based high-performance computing and other compute-intensive applications and are not meant to do perform graphics tasks. NVIDIA stated that its new Tesla solutions will deliver double precision performance in the range of 520GFlops – 630GFlops.

Previously it was widely believed that the new NVIDIA Tesla C2000 boards based on the Tesla T20 GPUs will feature 512 stream processors at 1.25GHz – 1.40GHz clock-speeds, the fully-fledged configuration of the company’s GF100 chip (also known as NV60, G300, GT300, etc) based on Fermi architecture at slightly reduced clock-speeds. However, NVIDIA decided to cut down the Tesla C20 GPU for some undisclosed reasons.
