NVIDIA Preparing To Strike Back With Fermi-Based GF100 GPUs

From DailyTech: NVIDIA has been under a lot of competitive pressure over the last year, but especially during the last four months as its primary competitor ATI has launched six desktop DirectX 11 GPUs and a complete Mobility Radeon lineup for notebooks. Over two million DX11 GPUs have been sold so far, all of them from ATI. NVIDIA had a fairly large presence at the 2010 International Consumer Electronics Show in Las Vegas, but also had a series of briefings for select members of the press the week after CES. The embargo date is today, and some of the details that were discussed can be revealed.

There are three things that most enthusiasts have expected from NVIDIA's next-generation gaming GPU based on the Fermi architecture. There was no doubt that it would sport a large die size, run hot, and be expensive. The big question was whether it would be more powerful than anything the graphics division of AMD could muster. NVIDIA has been promising everybody since its GPU Technology conference in October that it would "blow ATI away", but we're been waiting on the hardware while ATI's GPUs dominated the holiday shopping season.

NVIDIA is saying that GF100 chips are in production, but we don't have details on yields or how many wafers are being produced at the Taiwan Semiconductor Manufacturing Company (TSMC). GF100 chips are being produced on the 40nm process, and ATI has had a hard time with the process since it first began the transition in March of last year. The GF100 has over 3 billion transistors, 50% more than the Cypress GPU which is fairly large at 334mm^2. Initial reports are that the GF100 will exceed 500mm^2, which means that there will be a lot of chips that won't be able to run at full capabilities. We can probably expect defective chips to be used in cut-down GF100 variants.

The first boards will be launched at the end of February, with first availability in March. However, volumes will be a problem, and we have been hearing concerns from some board partners that there won't be enough chips to meet demand until April, at best. The initial flagship card will launch with 512 stream processor cores (which NVIDIA is calling CUDA cores), 48 ROPs and a 384-bit bus running GDDR5.
