Default NVIDIA Updates GeForce 600 OEM Desktop Lineup, Adds GT 645, GT 640, GT 630

While NVIDIA doesn’t publically announce most of their OEM desktop graphics cards, they do update their website with the specifications of these cards, which is how we usually find out about them. Today has been no exception, and after NVIDIA's latest site update a bit of digging has unearthed the fact that NVIDIA has released their first Kepler cards for the desktop market. There are 5 new OEM desktop cards, composing a mix of both Kepler and Fermi: the GT 645, the GT 640, and the GT 630.

If this product stack looks familiar, it should. It’s generally the same product stack as the GeForce 600 series Mobile lineup, except with higher clockspeeds. As with their mobile parts, NVIDIA is going to be mixing 40nm Fermi parts and 28nm Kepler parts into their desktop product stack, leading to a hilariously frustrating selection of video cards.

At the top of the new product stack we have the GT 645, which is a GF114 Fermi rehash. GT 645 has 288 CUDA cores enabled and paired with what’s listed as a very crippled 128bit memory bus. However considering the memory bandwidth NVIDIA lists for the card (91.9GB/sec) and the fact that they already have a very similar card in the GTX 560 SE, we’re confident that the 128bit bus in NVIDIA’s specs is a typo and that it’s actually a 192bit bus, and we are listing it in our charts accordingly. In any case you’re still looking at significantly less memory bandwidth the GTX 560 is typically paired with.
