NVIDIA Working On Kepler GK208 GPU

NVIDIA Working On Kepler GK208?
It appears that NVIDIA is currently working on the next generation of Kepler GPUs. A social-web profile of the NVIDIA’s GPU Architecture Intern has revealed that the company is working on a new Kepler GK208 processor.

Well, this could possibly just be a mistake, but it gets more interesting if we bring up two facts: there is no GK108 GPU (so it’s not a typo) and the note clearly says that he was employed between June and September 2012 for this project. Company like NVIDIA usually has the whole architecture prepared months before any release, so we are obviously not talking about any current Kepler processor.

Long story short, this information causes a lot of confusion. We were all convinced that the next flagship GPU of GeForce 700 Series would be GK110 or GK114. If the GK208 really exists then the whole line-up should consist of GK2xx silicones. This however doesn’t stop us from speculating. We can assume that NVIDIA might somehow modify the GK110 for consumer and rename it to GK114, GK204, GK210 or GK214.

Our sources told us that the upcoming flagship of GeForce 700 series — GeForce GTX 780 — would feature between 1728 and 2112 CUDA cores. If we assume that the GK208 would be an entry-level GPU then it could likely power the GeForce GT 740 or GTX 750. If the 192 CUDA cores SMX architecture would not be changed, then GeForce GT 740/750 might be packed with 576 cores (3*192).

Upcoming GeForce 700 Series graphics processors naming speculation

We assume that NVIDIA will continue releasing at least three GPUs for each series. This doesn’t mean that there might be four, or even more, processors coming with the upcoming ‘Kepler refresh’.

 Segment GeForce 600 Series (Kepler) GeForce 700 Series (Kepler Refresh)
 Current GPUs Variant 1 Variant 2 Variant 3
High-end GK104 GK110 GK114 GK204
Mid-range GK106 GK116 GK116 GK206
Entry-level GK107 GK117 GK118 GK208

I was asked not to provide a link to the profile of the Intern, because we (and our source) do not  want to cause any more trouble for the guy, but well… you will probably find his profile anyway.
