NVIDIA have reportedly released their GeForce GTX 660 GPU to the OEM market, and just like its bigger brother, the GeForce GTX 660 Ti, it sports the same GK104 core. But, it features just 6 SMX units enabled for a grand total of 1152 CUDA cores, as well as 96 texture units.

This is down from the Ti's 1344 CUDA cores, and 112 texture units. Frequencies have also received a bit of a snip, clocking in at 823MHz core, with an 888MHz boost clock, and 5,800MHz memory. The GTX 660 should arrive on OEM doorsteps with 1.5GB and 3GB GDDR5 configurations, a 192-bit memory bus, which should offer a maximum bandwidth of 134GB/s. This isn't bad considering the 660 Ti sports 144GB/s memory bandwidth.

The GTX 660 OEM should provide around 75% of the performance that its bigger brother does, but with lower performance brings a lower TDP, of just 130W. This allows NVIDIA to give the GTX 660 a single 6-pin PCIe connector. It will still include the usual four-display output configuration, featuring two dual-link DVI-I connectors, HDMI 1.4a, and a DisplayPort 1.2 socket.
