GTX660OEM.jpgIt would appear that Nvidia has decided to give its OEM partners early access to at least one version of the upcoming GeForce GTX 660 graphics card expected to be based on Nvidia's GK106 GPU. The company has posted details of the new OEM card on its websites, but didn't disclose which GPU the card in question is using.

The OEM GTX 660 GPU is said to feature 1152 CUDA cores/shaders, 96 texture units and 24 ROPs, with a base GPU clock of 823MHz and a boost mode of 888MHz, nearly 100MHz slower than the stock clocked GeForce GTX 660 Ti retail cards. Previous indications have suggested similar GPU clock speeds for the GTX 660 as the GTX 660 Ti, so we'll have to wait and see what the retail cards are like.

As for memory, the OEM GTX 660 cards will come with 1.5 or 3GB of GDDR5 memory with an effective clock speed of 5800MHz on a 192-bit bus that produces a memory bandwidth of 134GB/s. This is 10GB/s less than the GTX 660 Ti and this would of course be due to the slower clock speed of the memory.

One interesting thing which does line up with earlier rumours about the GTX 660 is that the OEM card is rated at a 130W maximum power draw and as such only comes with a single 6-pin power connector. This would "limit" GTX 660 to 150W – 75W via the slot and 75W via the power connector – so don't expect to see some highly overclocked versions of this GPU, unless it's fitted to a custom PCB with additional power connectors, once the retail version arrives.

As far as display interfaces are concerned, nothing has changed compared to the GTX 660 Ti and as such we're still looking at two DVI ports, one HDMI port and one DisplayPort connector. The physical size of the OEM GTX 660 is the same as for the reference design GTX 660 Ti card. The only way to get your hands on one of these cards will be to pick up a system from one of the large OEM's like Dell or Acer, but we'd suggest to wait and see what the retail cards will be like, as they're less than a month away.

That is really what i need, a Geforce GTX 660 sweet!
PNY GTX 660 ti no triple play love. only dual display on any two combination of connectors. I'm going to return the PNY GTX 660 ti and ASrock H77M-ITX and wait for gigabyte to release there Z77 jammy. By then I hope triple monitor support will be available and the cars will be a bit cheaper..Keep us posted guys.
