NVIDIA To Release Four GK106 Graphics Cards

NVIDIA To Release Four GK106 Graphics Cards geforce gtx 660 geforce gtx 650ti
WCCFTech got their hands on an interesting SKU listing of upcoming GK106 GPU based graphics cards. According to it, NVIDIA is preparing at least four models based on this GPU.

Even though we have the exact GPU codename, memory size and memory interface we don’t know how will those GPUs differ. Most likely NVIDIA will reduce the number of CUDA cores for each iteration. We can assume that GK106 is a replacement for GF116. This predecessor was released in three versions: GF116-400, GF116-200 and just a GF116 (I hope I’m not wrong here). According to the listing there would be four iterations of GK106 with some mysterious GK106-250 version. We can assume that this GPU will be a slower version of full GK106-400 with 960 processors. I would call it a GeForce GTX 660 SE, since GK106-200 will most likely power the GTX 650 Ti (with 128-bit interface), which should be released next month. There’s also a version for workstations – GK106-875, which might be a mid-range Quadro card.

Anyway, here’s the original table and my predictions, feel free to join the rumor mill.

    It would make sense for it to go that route, however I’m curious as to at which number of cuda cores they will take another ROP unit away, bringing it down from 24 to 16. Damn, I really wanted 1152 Cuda Cores and 24 Rops, a perfect 3/4 of a gtx680 for half the price. It would have been nice to run two of those, but NV probably realized what a mistake it would have been to release cards that good at that price range, though, I have to say, the GTX660Ti at $299-349 is simply way overpriced. A 660Ti at $249 would be nice. In due time I suppose.

    Sorry, I meant $299-339. I haven’t seen one for $349, thank god!

    You have it wrong. GK106-200 has 128 bit RAM.
    Thought some of these might be OEM cards, thus what they would release is still unknown.

    Yeah, didn’t notice that.

    2x 1152 / 24 ROP would still barely will barely touch a single high-end card. GTX660Ti SLI is just 20% faster than an HD7970 GE at 1080P, and only 6% faster at 1600P.

    Considering HD7970 GE has way more overclocking headroom and SLI scaling issues that are bound to come up, it would really be a total waste of $ to get GTX660 SLI. If you want to go with 2 cards, your best bet is to wait for a deal on GTX670 SLI or HD7950 CF + OC, or wait for next generation cards (if GTX780 is flagship, GTX670 level of performance should be $299). Budget cards have always been horrible for cross-fire and SLI since slow GPUs exhibit the most micro-stuttering and 2 of them combined can hardly outperform a high-end GPU since SLI/CF scaling is not 100%.

    “budget cards have always been horrible for cross-fire and SLI” – This is not true. The GTX460 was a fairly budget card ($199-229) and in SLi that set up screamed (still does actually). That’s what I’m looking for. The 660Ti is still too overpriced. I’d like to find $199-239 pricepoint rather than the $299-239 that the 660Ti is. If they do not price it as they should, I may end up going with a couple AMD 7850′s. Either dual 660′s or 7850′s will net me the performance I’m looking for (60+fps in just about any game today at 1920×1200 w/4xmsaa), and will perform greater than a single gtx680 or 7970GE, check out the bechmarks for that setup. Not too shabby.

    I had great performance with 2 GTX 460′s in SLI and they scaled rlly well. Honestly, I never really noticed micro-stuttering with them. However, I recently got a pair of GTX 480′s for cheap on ebay and noticed a fair amount of micro stuttering during Crysis 2. Not sure if it’s worth the upgrade to the two GTX 660 but, the noise from the 480′s is just annoying. I have to put both of them up at %100 so they don’t overheat. Is the 7970′s fan just as loud ?

    I wouldn’t buy a reference 7970. GTX660 is barely better than those 480s. Actually 480 overclocked to GTX580 speed and 660Ti is barely faster than a 580. If you want a quiet card from either NV or AMD camp, I recommend:

    Asus DirectCUII (quietest GTX670)
    Gigabyte Windforce 3x
    Sapphire Dual-X, Vapor-X
    PowerColor PCS+ (quietest 7950)

    If you already have 480s, I would skip any card from this generation. Even GTX680s are just 40% faster than what you have. Honestly wait for HD8000/GTX700 series at this point. Set up a custom fan curve on your 480s and change the Thermal paste!!

    This should drop your temperatures 5-6*C and let you run the cards at lower fan speeds.

    If you can find a buyer for your 480s, sell then and grab HD7950 Cross-fire. Best bang for the buck from 480s if you don’t mind overclocking. Otherwise, wait 6 more months for next generation and you’ll get better value.

    It’s definitely true. GTX460 SLI was good on paper but GTX580 provided superior gaming performance. Looking at the specs of GTX650/660 in another thread, GTX670 will smash GTX650 SLI and GTX680 OC will be nearly as fast as GTX660 SLI. The problem with SLI (or cross-fire) is that some games don’t scale well and you get micro-stutter. I would never buy $149 GTX650 x 2 over a GTX670. That’s just throwing $ away.

    Also, HD7970 GE is 75% faster than a single 7850. Sure you can overclock the 7850 but you can overclock 7970 GE as well. Cross-fire and SLI only makes sense for higher-end cards such as GTX660Ti SLI / 7950 CF or faster. As games become more demanding with Crysis 3 and so on, the limitations of lower texture fill-rate on 660 will show up in a heartbeat! GTX680 has 64% higher texture fillrate than a 660.

    You are making a very big mistake thinking that 2 low-end videocards can provide the same level of smoothness in games that 1 single fast high-end card can. You are probably just starting with your 1st or 2nd PC gaming rig so I’ll give you the benefit of the doubt :). You cannot compare frames per second for dual-GPUs to single-GPUs since they are not the same.
