NVIDIA’s GeForce GTX 660 Has 960 CUDA Cores, MSI Power Edition Pictured

OBR-Hardware has some interesting pictures of the non-Ti version of GeForce GTX 660. According to his data, the new GTX 660 will be powered by GK106 GPU with 960 CUDA cores.

Long story short, the OEM version of GTX 660 has 1152 CUDA cores, while the retail has only 960! That’s very surprising.

We have a very detailed information straight from the data-sheet of MSI GeForce GTX 660 Power Edition. The another surprising fact is that card would still use the same 2GB 192-bit memory as the Ti version. New GeForce GTX 660 would feature a 980/1032 MHz – base, boost clock respectively, while the memory is still clocked at 6GHz.

MSI’s card looks similar to the Ti version and it looks like the manufacturer has only changed the GPU. The Chinese source says that GTX 660 non-Ti will feature the reference design known from GTX 670, GTX 660 Ti and GTX 660 OEM, so it would actually make sense – we should see another iteration of the same Phantom, DirectCU II, TwinFrozr, AMP! and GC designs.

The data-sheet suggest that GTX 660 would consume up to 170W, but this might be related to increased TDP of factory-overclocked card. The non-Ti version might still require two 6-pin power connectors.

GeForce GTX 650 Picture

The Chinese forums have also leaked this picture, its a GTX 650 (the non-Ti model). As you can see it comes with black design, but it’s identical to the GT 640. If you didn’t hear it already, the GTX 650 is GK107 based graphics card with 384 CUDA cores. The main difference between GTX 650 and GT 640 is the memory type – GDDR5 for GTX and GDDR3 for GT model.

Performance

This performance chart is presenting the performance of all three mid-range cards. The first graph (red bar) is showing the Heaven 3.0 performance, the second (green) is Dirt 2, while the third (blue) is unknown. The second chart is giving a quick reference of 3DMark11 performance – according to it, GTX 660 is 30% slower than GTX 660 Ti.

    Typo:
    “GK106 would be clocked exactly the same as GK104-based GTX 660 Ti — 980/1032 MHz”
    No GTX 660 Ti: 915/980 Mhz base/boost

  • http://videocardz.com/ VideoCardz.com

    I meant the MSI’s GTX 660 PE to GTX 660 Ti PE. Both factory-overclocked.

  • skr13

    In that case, yes the clock/boost is the same.
    660 OEM has 1 SMX more but lower clock, vram, they should perform the same.
    That OEM card is for ACER Computer, i remember 1.5 Vram.
    GTX 650 maybe 128-bit bus.
    HA, MSI hates you one time more :)

  • http://videocardz.com/ VideoCardz.com

    MSI should be mad at OBR :)
    but take a look at the left side of the box – it has Ti branding.

  • skr13

    But Videocardz is more known than OBR, and many websites copy info from here.
    yeah, barely can see that Ti.

  • not a loyal fanboy

    price ?????
    I welcome the 2gb for 660

    Sounds like a step back from the OEM in some sense. You can overclock the OEM card to 1100-1200mhz I bet but you can’t just add the missing CUDA cores through drivers! Also, it looks like it was done to include 2 GB of VRAM since most people now wouldn’t touch a card with 1-1.5GB of VRAM and a 3GB version wouldn’t be as price competitive. I can see why NV did this then. This card should be much slower than the GTX660Ti. That could confuse a lot of the consumers who think a GTX660 card is as fast as an HD7950.

    I actually prefer AMD naming scheme, They changed it a bit when Radeon HD 5870 went into HD 6970, but still it’s more clearer for customers to understand it. Also it’s very a intelligent move to release old cards as entry-level models from next generation (NVIDIA should go the same way, instead they launch GT 640).

    This Ti branding doesn’t make things any better. Now we have three GT 640′s and three GTX 660′s.

    GT 640 isn’t bad. It has low power consumption and perfectly fits into the place of GT 440. If they added DDR5 into it, it would be completely fine. GTX 550 Ti would probably tank, but it still has better memory bandwidth thus there would be sales, and NVidia would fulfill expectations of one/two generation later card that have similar (or higher) capability as an old one bin higher card.

    Current silent gaming PCs have only three choices: Zotac GT 640 (DDR3 only kinda tanks it, and power supply isn’t something to write home about, but it probably does its job). Gigabyte 6770. Saphire 7750 (I seen really funny RMA rates). Without GT 640, NVidia side would have only Asus GT 440, and Asus GT 450 (Zotac gets honorable mention for its low speed DDR3 instead of DDR5 and lack of 6-pin connector). There is yet another alternative, getting a card which manufacturer will not void the warranty someone would play with cooling, rip away original cooling solution, and add Accelero, or a water cooling.

    NVidia re-branded GT 440 to GT 630, thus they DO follow the suit. However what would be the point of re-branding GTX 550 Ti into GT 640? It has higher power consumption, manufacturing costs are probably higher as well, thus price will not be favorable, and the only advantage against GT 640 with DDR5 memory is 192 bit memory interface. GTX 560 SE with 1.5-3 GB RAM would be better replacement, as long as they could guarantee its power consumption wouldn’t be higher than GTX 550 Ti OC edition (basically it would need to be a undervolted and underclocked edition with SW voltage regulator and high overclocking potential).

    LoL I was so right two months ago :

    ” I bet the GTX 660 will be a slow card based on a GK106 clocked around 1
    GHz, and GTX 660 Ti will be a much faster card based on GK104 but it
    will be much more expensive.”

    Sorry you lost me at gaming PC and ZOTAC GT 640… Gaming PC with GT 640? :)

    What I’m trying to say is that there should be a simple way of dividing old GPUs from the new ones. Right now we have old ones with GT 610-630, then Kepler GPU and in total too many similar cards, and we are not sure which is the mid-range and which is high-end. With Radeon HD 7700 or 7800 we know these are mid-range card, while 7900 is high-end, very simple.
    NVIDIA has
    GT 610,GT 620, GT630, GT640,
    GTX 650, GTX 660, GTX 660 OEM, GTX 660 Ti
    GTX 670, GTX 680, GTX 690
    There are too many cards with similar performance -> 660 Ti @ 670, 670 @ 680 and a huge gap at mid-range.

    GTX 660 shouldn’t be slow :)
    But yeah, you were mostly right

  • http://twitter.com/deeree2009 Dee

    They might be. I clicked on the link to OBR’s website and there is no info about the card. Maybe I’m blind, but looks like he took it down, lol

  • http://twitter.com/deeree2009 Dee

    According to Wccftech, the price is rumored to be $229-249. I’m hoping for $200

  • http://videocardz.com/ VideoCardz.com

    Well there are possibly two reasons.
    First is that one picture was clearly not ASUS GTX 660 (it’s a TI model). Also MSI might not be the non-Ti card.
    The second is that MSI might have asked him to remove the post. The article on techPowerUP has been deleted too. Well this one will not be deleted :)

  • Ricoo

    24 % slower than Ti in 3DMark11 performance is rather bad, almost 4 times slower than 560 compared to 560Ti. :/

    In 3Dmark11 performance 560 is only 6 % slower than 560Ti.

  • yang

    it is about 20% less performance compared to gtx660ti, so the reasonable price is 200, if Nvidia charge 249, customers will be fooled

  • Gytis

    Will it beat HD7870?

  • ipwn3r123

    So GTX 660 OEM have more CUDA cores then the retail GTX 660…?

  • http://videocardz.com/ VideoCardz.com

    Yes.

  • ipwn3r123

    Do you think the less CUDA cores on the retail GTX 660 will impact on the performance?

  • ipwn3r123

    Does the lesser CUDA cores for the retail GTX 660 will impact on performance?

  • http://twitter.com/deeree2009 Dee

    Wow, you can tri-sli these things. 960 X 3 = 2880 Cuda Cores ! You can have the power of GTX 780 early, lol

    Usually three things have the biggest impact:
    - stream/cuda processors (depends on the architecture)
    - number of raster operating units
    - memory bus width

    So yes, there will be noticeable difference.
