Nvidia details GeForce GTX 660 OEM boards

Nvidia's latest OEM card is a cut-down GeForce GTX 660 Ti, and the first Kepler card to come in at under 150W TDP.

Details of Nvidia's GeForce GTX 660 OEM have been released, providing the first clue of what manufacturers looking for a cut-price Nvidia-manufactured equivalent to the recently-launched GeForce GTX 660 Ti will be getting.

Based on the same GK104 Kepler-based GPU as the Nvidia GeForce GTX 660 Ti, those expecting equivalent performance are likely to be disappointed: according to Nvidia's figures, the OEM version drops the number of CUDA cores down to 1,152 from 1,344 and the number of texture units down to 96 from 112. The clock speed also takes a hit, with the core clock dropping to 832MHz from 915MHz and the boost speed dropping to 888MHz from 980MHz.

The OEM cards include GDDR5 memory on the same - sadly limiting - 192-bit bus as their bigger brother, but running at 5.8GHz rather than the 6GHz-and-change of the Ti model. There's also no 2GB version available, with OEMs given the choice of cheaping out on a 1.5GB model or wowing buyers with big numbers by packing 3GB of GDDR5 graphics RAM into their systems.

It's not all bad news, of course: the GK104 is the same 28nm TSMC-manufactured part as found on the Ti, albeit with some hardware disabled - and that has a benefit in reduced power draw, with the GeForce GTX 660 OEM given an official thermal design profile of 130W to the GeForce GTX 660 Ti's 150W. That latter could be of quite some interest to system builders: no other Kepler card comes in at less than 150W [EDIT: except the power-sipping 65W GT 640 and its OEM-only GT 645 counterpart] and the GeForce GTX 660 OEM simplifies wiring by requiring only a single PCI Express power connector.

The quiet launch of the GeForce GTX 660 OEM suggests that Nvidia may be planning to offer parts with similar specifications to its hardware partners for the launch of a non-Ti retail GTX 660. Assuming the disabled hardware doesn't cause too much of a performance drop, and hoping that board builders can get the price down to near £200, Nvidia could be on to a winner with that plan.

For now, however, the GeForce GTX 660 remains an OEM-only part, with no official news of a retail launch. Pricing is also being kept very quiet, with Nvidia silent about just how much OEMs will save over buying the more powerful GeForce GTX 660 Ti for their gaming rigs.

Full specifications for the board are available on Nvidia's website.

hmmm rumour mill says the GK106 will be the GTX 660 retail part , with alot less spec than the OEM part ; although its not the first time nvidia have sent 1 part to oem`s and the sanem named part but less spec to retail - GT 440 springs to mind here

to me it says nvidia doesnt want a 660 in retail and it could likely become the OEM card only and theres plenty of them. If they wanted to release the 660 it would of been out by now not just available at OEM.

Except for the GT 640.

Isnt the GT 650 the same as the GT 640 but with DDR5?

I thought the GT 650 was a mobile-only part? <goes to check> Yup, Nvidia shows no GT 650 - but it does have a GT 650M.

Wow. I cant wait to play Battlefield 3 @ 7680x1440 on this, with everything turned up high. 3GB of GDDR5!!!

I suppose future GTX660 owners should be grateful Nvidia didn't try to push DDR3 on to it.

Got to agree, at least it isn't 3GB of DDR3, and is proper GDDR5. Admittedly, it's still a total waste of memory, but for those who get the 1.5GB cards it should be okay.

Fingers crossed this sees a retail launch.

its something i thought i had read - the OEM GT 640 DDR5 would be named the GT 650 in retail..... ofc i could just be completely mad ;)

not like its designed to play games at 7680 rez and anyone gaming at that res is unlikely to be doing so on a prebuilt oem machine

One of the worst moves ever to be made by nVidia, to not release a $200 GPU for the endconsumer-market.

There's no competition for AMDs 7850 for over 6 month now, and the older GTX560ti couldn't match the performance of it. And even worse, the 7850 was as good as the GTX570 in most cases, but way cheaper, drawing way less power.

Does nVidia really want me to buy a 7850? I can get a Sapphire 7850 OC in stores for €190 currently.

Seriously nVidia... release that GTX660 nonTi for the endconsumers allready!

I cant See How Nvidia are going to compete I've seen some 1GB 7850 for £130 and 2GB for £145.
After the GT 640 released I guess that the more lower end Nvidia is going to go with Kepler the lower price/performance ratio they will have
