The GK107 GPU

With the release of the Kepler architecture in March of this year, NVIDIA has once again seemed to take back the hearts of PC gamers with a GPU that is both powerful and power efficient. The GK104 has seen a product implementation as the GTX 680, the dual-GPU GTX 690 and most recently as the GTX 670. With a price tag of $399 though, there is still a very large portion of the graphics card market that Kepler hasn’t touched but is being addressed firmly by AMD’s Radeon 7000 series.

Today we are going to be taking a look at NVIDIA’s latest offering, the sub-$100 card known as the GeForce GT 640 based on a completely new chip, the GK107. Specifically, we have the Galaxy GeForce GT 640 GC factory overclocked card.

Compared to the GK104 part, GK107 is a much smaller chip and the GT 640 implementation of it contains two SMX units and 384 CUDA cores. That is a significant drop off compared to the GTX 680 (1536 cores) and the GTX 670 (1344 cores) but it should really come as no surprise to those of you that follow the NVIDIA GPU families of the past.  The chip will have 32 texture units and 16 ROPs. 
 

More confirmation, NVIDIA is leading the 600 series with mobile chips

VR-Zone spotted a string in the newest beta drivers from NVIDIA listing two new models of GPU, the NVIDIA GeForce 610M and GT 630M.  From other rumours that we have collected from a variety of sources around the web we are fairly certain that these chips will be based on GK107, the low power version of the chip everyone wants to see, the GK100.  While we are used to seeing both AMD and Intel to lead with mid to low range chips to simultaneously start off a new process size and chip family, NVIDIA doing so raises some eyebrows.  NVIDIA's mobile graphics chips have to compete directly with the graphics portion of AMD and Intel's APUs and do so in a market where like it or not, you have already paid for the GPU portion of your processor.  There will not only have to be an increase in performance, it will also have to justify the extra investment.  We shall see what the final answer is early in 2012.

"In the latest unreleased 285 BETA drivers, the expected GeForce 600 branding has surfaced. The marketing names leaked are NVIDIA GeForce 610M and NVIDIA GeForce GT 630M. The GeForce 610M is likely to be an entry level GPU while the GeForce GT 630M could very well be a GK107 SKU."

It's confirmed, NVIDIA won't be leading with the big Kepler

Tagged: nvidia, kepler, GK107

As SemiAccurate reported back on the 21st, Kepler will be arriving in the form of a bottom to top release, not the top down that many enthusiasts were hoping for.  The reason for this is a popular topic of speculation, the most likely suspect being that this is not only a process change, to 28nm; it is also an architecture refresh and pulling off both of those together is a tricky proposition at the best of times.  VR-Zone also provides insight into the code names, with the P suffix indicating a lower powered chip, likely a replacement to the GT 500M while the E suffix denotes an enthusiast mobile chip more in line with what the GTX600M is currently.  More spoilers available in their post.

"GK107 is set to feature in four mobile GeForce SKUs - N13P-LP, N13P-GS, N13P-GT and N13E-GE. If these codenames sound familiar, it is because they have previously appeared in a leaked 28nm mobile GPU line-up. GK107 features a 128-bit memory interface, and supports DDR3 and GDDR5 memory. The first three GK107 based SKUs (with a "P" suffix) will likely succeed the GeForce GT 500M series, and will presumably be branded GeForce GT 600M series. The top GK107 part, N13E-GE, may succeed GTX 560M and be part of the GTX 600M series, as denoted by the "E" suffix (Enthusiast). In addition, GK107 will also be part of mobile Quadro SKUs - N14P-Q1 and N14P-Q3."

Kepler has arrived ... sort of

The news on the street is that two chips from NVIDIA's Kepler lineup should be arriving relatively soon, but don't get too excited.  The GK117 will be a hybrid Fermi/Kepler card, not a GPU but perhaps a powerful addition to any render farm or other application which can benefit the new architecture.  It could also just be a test chip the NVIDIA created to test the integration capabilities of the two architectures.  The GK107 seems to likely be a mobile part, something SemiAccurate dismisses quickly as it will have to compete with the integrated GPUs present in both AMD and Intel mobile chips. 

There is no sign of the Kepler everyone is waiting for, the GPU that will power NVIDIA's next generation of graphics cards.  Why haven't we seen any sign of it yet?  Drop by SemiAccurate for speculation on some of the possible reasons.

"Nvidia has two Kepler parts taped out and likely back in house by now. They are however, not the fire-breathing big chips you would expect.

Sources tell SemiAccurate that the first Kepler chips taped out about three months after the first 28nm Fermi shrink taped out. If you remember when we exclusively told you about the dates on those about a month ago, now there are a few more details to add."
