@ 2012/08/23As is typically the case for NVIDIA when it comes to OEM products, they have once again quietly released their newest OEM video card. Their latest OEM addition is the GeForce GTX 660 OEM, which comes hot on the heels of last week’s launch of the retail GeForce GTX 660 Ti.
The GTX 660 OEM is another GK104 based video card, and like NVIDIA’s other OEM Kepler parts it’s a fairly conservative configuration. NVIDIA is shipping this card with only 6 of 8 SMXes enabled, the first time we’ve seen a desktop GK104 part with fewer than 7 SMXes. This further reduction in SMXes brings the GTX 660 down to 1152 CUDA Cores and 96 texture units, while on the raster side of things it’s unknown whether NVIDIA has disabled a whole GPC, or if they’re disabling SMXes in two separate GPCs. Meanwhile like the retail GTX 660 Ti this part has also had a ROP/L2/memory cluster disabled, giving it the same combination of 24 ROPs, 384KB of L2 cache, and a 192bit memory bus.
Looking at its specs NVIDIA seems to be particularly interested in getting a sub-150W Kepler card out – the GTX 660 OEM is rated for 130W and only requires 1 PCIe power connector – so compared to the other desktop GK104 parts the clockspeeds have also taken a hit. The GTX 660 OEM is clocked at just 823MHz core with an 888MHz boost clock, which is about 10% lower than the GTX 660 Ti. The memory clock is also a hair lower at 5.8GHz, an odd configuration since it means NVIDIA still has to equip the card with 6GHz GDDR5. At the same time NVIDIA is equipping the GTX 660 OEM with a fully symmetrical 1.5GB or 3GB of RAM, which coming from the asymmetrical 2GB GTX 660 Ti is probably a combination of cost-cutting and recognition of the fact that the OEM market isn’t quite as finicky about memory capacity as the retail market is.
