NVIDIA GeForce GTX 660 Ti Final Specification

NVIDIA GeForce GTX 660 Ti Final Specification geforce gtx 660ti
NVIDIA’s GeForce GTX 660 Ti has a really impressive numbers. According to SweClockers, GTX 660 Ti and GTX 670 will only differ in the memory interface width.

SweClockers claim that they came across the final specs of upcoming mid-range GTX 660 Ti, card that is said to offer slightly worse performance than GTX 670. Well, numbers are quite clear, the only difference between these two is the memory bus width — with 192-bit for GTX 660 Ti and 256-bit for GTX 670. Narrowed memory interface will decrease both the memory bandwidth and power consumption. The GTX 660 Ti will have a TDP of 150W, with a requirement of two 6-pin power connectors. Memory bandwidth will drop to 144.19 GB/s (that’s 48 GB/s less than GTX 670). Furthermore the GTX 660 Ti will hold the same memory capacity of 2GB (GDDR5). When it comes to the frequencies of all clocks — these are the same for both cards (but this might change before launch).

GeForce GTX 660 Ti will almost certainly use Kepler GK104 GPU with the same amount of SMX clusters holding 1344 CUDA cores. This would also indicate that it will have 112 TMUs and 32 ROPs. This mid-range card will have a very short PCB, which is almost identical to GTS 450′s.

Since there is no update regarding GTX 660 non-Ti variant we won’t speculate about it. Although if OBR is correct, then the non-Ti model will offer a performance of GTX 580, while 660 Ti (when overclocked) a performance of GTX 670.

GeForce GTX 660 Ti will launch on August 16th. According to the source, the availability of the graphics card will be relatively good, indicating that the GTX 660 Ti will hit stores as early as the launch day. The price is still unknown but the latest rumors say that it will cost around $320-$330.

    I hope a good performance competing with 7950, and if the price dont exceed 300, will be the best seller. 2GB Vram is great. Non TI 660 maybe feature 1.5vram, but that is fair for the card segment.

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

    Yes, wrong translation. Anyway 660 Ti will definitely be one of the most popular cards (if the price sets below $330).

  • skr13

    According to this post, “Vendors have plans to send a sample card …” some partners will receive a card sample soon, and maybe a performance graph leak appear or a Preview(more later) like Tweaktown made with gtx670. Thats my thoughs ;)

  • not a loyal fanboy

    I would hate to raise my budget from $250 & below USD to $300 USD as prices in my country have 20% premium after exchange rate.

  • BestJinjo

    Good to see them going with 2GB of VRAM. 1.5GB would have been a massive disappointment on a $300 card. Since GTX680/670 and 660Ti are all made not the same GK104 chip, this lands even more credibility that GK104 is just a mid-range Kepler chip. NV hasn’t built a line-up of mid-range and high-end cards based on the same chip since GeForce 4 Ti series. GK104 must be relatively cheap to manufacture if NV is willing to sell the same chip in both the $300/400 and 500 price levels.

    I still don’t understand how those specs make sense theoretically though. In GK104, the ROPs are broken up into 4 blocks of 8, with each ROP block tied to a 64 bit memory controller and 128KB of L2 cache. Altogether there are 32 ROPs, giving 512KB of L2 cache and a 256bit memory bus. How can this card still have 32 ROPs but only 192-bit memory bus?

  • BestJinjo

    The 7950 would still be the better card for enthusiasts. With its 35-40% overclocking room, the GTX660Ti will have no hope to catch it with that crippled memory bus. At stock speeds, the 660Ti should be good though.

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

    US Prices are always lower by ~20%. I had to pay $475 for my GTX 670 and that was the best offer I could find :)

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

    Nice find, although the post does not reveal WHEN would they send it.
    At least we know it’s coming :)

  • Michael

    WIll there be a non-Ti version?

  • BestJinjo

    Ya, there has to be. It may be called GTS650 or GTX660. NV needs to release Kepler cards below $300, so GTX660Ti can’t be the last Kepler card this generation on the desktop.

  • BestJinjo

    Right, but when it comes time to upgrade and resell your card, I bet in the used market you get a higher resale value than us.

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

    Not sure about that, when I bought my gtx 670, there were already $400 worth 7970 available (used). That depends on the specific model, people now tend to sell their 7970. Haven’t seen any 7950 or 670 though.

  • skr13

    If is a mid-range kepler chip, but enough to compete with high end tahiti, why not? Is cheap to manufacture like you say, and profit is guarenteed. Still don´t understand how it has 2GB Vram? 2048/8=256bit so 1536/8=192bit…
    Yes and the ROP´s question is relevant, 256/8=32ROP´s so 192/8=24ROP´s…
    Maybe is not a GK104 chip, if you read Sweetclockers there is “GK104 (?)” in chart.

  • Jerome

    The 670 is a competitor to the 7950, anyways the 660ti will be crippled by its memory bus width before anything can even use that 2GB of vram. The price for the 660ti seems way too high!

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

    Well Sweclockers report that the price is 3000 SEK and thats $436 … but with European taxes, so you take around 20% and here’s the price.

  • BestJinjo

    Ya, NV engineers did an amazing job with GK104 for gamers. I was waiting for GK110 because I want the compute performance but it never showed up. I would have paid $600-650 for a GK110 with 1Tflops of double precision compute, but because NV never came through, I had to go with AMD this round. Oh well, maybe next year then. I am not holding my hopes high though since next round of cards is still stuck on 28nm, so maybe have to hold out for Maxwell in 2014.

  • SalemSwift

    Well, I’m officially glad I waited for a GPU purchase. I’ll still wait on benches and street price, but…yay.

    quoted from the thread
    [660的TDP为120W,频率980/6000,且支持BOOST,BOOST 频率为1032]

    not sure if the clockspeed is refering to 660 or TI

  • BestJinjo

    Right, but you waited 6 months now since HD7850/7870 were available. 6-7 more months from today and we’ll have HD8000 series GPUs, which will be even better than current cards, while HD7950/7970/670 cards will have huge discounts. No matter how long you wait, something faster and better will come out, while current high-end hardware will drop in price by 40-50% since its launch prices. So you still can’t win playing “the waiting game.” :)

  • BestJinjo

    Exactly, but a lot of people will buy a card just because it is NV and/or because they may not overclock. AMD should have shipped HD7900 series with 1100mhz clocks and this generation would have been theirs from the start. I think there is more to it though. Also, remember when AMD launched HD5850 for $270 and HD5870 for $370 and sold those cards with no competition for 6 months? Even then it barely took away market share from NV and people were STILL buying GTX285 over the HD5850….. So, even if AMD launched HD7950 at $270 and HD7970 at $370, many people would still be buying NV or wait 6 months until NV brings something out that’s 5-10% faster……it’s just how it is. Even after AMD re-took single-GPU performance with 7970 GE + new drivers in games such as Crysis 2, SKYRIM and Dirt 3, and closed in BF3 difference by 5%, you still have people saying NV makes faster cards, even if it’s not even true anymore.

    And probably my favorite: if NV is leading in the benches , then it’s the best GPU for your money. If AMD is leading, you won’t see the difference in the gameplay and buy NV anyways. LOL!

  • skr13

    If all HD7000 series launch at right price i had choose AMD, i came from 560ti and want something more powerfull but wont break 300 Euros. But of course Nvidia drivers and personalized options for each application/game is a plus.
    The only card that i had overclock was GXT460 edit bios and flash it(nibitor), but after that i use MSI Afterburner, more safe and easy to use.
    7950 -300Euros i had buy it, not like 450 Euros(launch price). In my country none of 7970ghz exist in market , and 7970 “normal” is at +450Euros, a steal. A GXT670 is about 420Euros.

  • not a loyal fanboy

    I frequently see Nvidia Asus Apple fanboys online that insist on buying these brands even when there are other brands offering better value-for-money.

    When 7850 came out, fanboys continue to buy 560 TI twinfroz that is more expensive by $50 while praising the benefits of physx and cuda
    Months later they sell it off taking $100 loss with barely anybody willing to take it off their hand

  • skr13

    LOL, MSI 560TI when 7850 came out, was less expensive, and today continues that.
    http://www.kuantokusta.pt/precos/nm_pesquisa.php?pesquisa=560+twin+frozr 217.90 EUR(560ti)
    http://www.kuantokusta.pt/precos/nm_pesquisa.php?pesquisa=msi+7850 244.99 EUR(7850)

    And this are lower prices for that models in the market, 560ti or 7850 are a good upgrade for ATI4000, or NV200 series.

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

    There is, but prices are much lower.

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

    They are talking about non-Ti model based on GK106, which is still a mystery for us. The most important information is that GK106 will have a boost clock, that’s GTS 650 and GTX 660 non-Ti.

  • not a loyal fanboy

    I don’t live in north america or europe

    the prices here is ridiculous
    during march-april , 560 TI $379 , sapphire 7850 $325, asus 7850 $409 , numerous 7870 in $479+ range
    now … 560 TI $339 , sapphire 7850 $325 , asus 7850 $409 , 7870 $429 and above

    even the coolermaster 212 evo and AIO watercooling kits are at 50% premium after exchange rate

  • BestJinjo

    Ya, I think “not a loyal fanboy”‘s comment was in relation to the prices in his country (i.e., 7850 cheaper than 560Ti) and despite that people still buying NV cards. Obviously, if the prices are cheaper where you are, then it’s a different story. Still 1.28GB of VRAM, worse overclocking on the 560 and lack of DX11.1 may prove to not be worth the savings of 30 EUR long-term, especially since HD7850 will quickly make it up in idle and load power consumption costs.

  • BestJinjo

    Wow that sucks. I hope where you live makes up for it with beautiful women, nice weather and delicious food, not the genetically modified crap we have here in North America. Try finding “real organic” fruit in NA that tastes good. Don’t even get me started on the meat. When I was in Brazil 2 years ago, the steak there melts in your mouth because the cows are grass fed, not corn fed. Here they call it Kobe beef and charge $200 for a steak of similar quality. Even the $60-70 steaks at high-end steak houses don’t even come close to the basic stuff I tried in Sao Paolo. And the women, let’s not even go there. The grass is always greener on the other side I suppose. If I ever visit your country (wherever you are), I’ll drop by and bring over a much cheaper GPU for you :)-

  • SalemSwift

    I didn’t wait 6 months, though. I’ve only been in the market for a card for a little over a month. I’m a seasonal gamer and don’t typically have a gaming system year round, frequent upgrades or sales. Now that things are winding down for me work-wise, I’m building another PC.

  • skr13

    By the way ;)

  • Jerome

    If compute is what you wanted then you should have waited a couple more months for Sea Island GCN 2.0. 7000 series already crushed eveything out there in compute already, except for GK110. You sound a little sad that you ended up with AMD this round which is confusing to me since AMD is in the 28nm lead right now.

  • BestJinjo

    Ok cool, Great timing then. Price wars are about to begin with GTX660Ti vs. 7950.

  • BestJinjo

    NV delivered a mid-range Kepler from their family with crippled compute functionality, while AMD’s best card is only as fast as that GK104 chip (GTX680). So why would I be thrilled about the fact NV held back performance and decided to sell GK100 as K20 to professionals, while AMD released a massively underclocked 7970 card that I had to manually overclock? GTX680 is just 30-40% faster than GTX580 overall. I was hoping for a 500mm^2 die GPGPU compute + gaming chip from NV to give a much larger performance increase. GTX680 and 7970 are good cards, but nothing special compared to what many expected from this 28nm generation. With early drivers, a stock 7970 was just 20-25% faster in January-February 2012 over a GTX580. That was very underwhelming. Both teams disappointed this time imo.

    Compare HD5870 vs. HD4870/4890 and GTX480/580 vs. GTX280/285. Both were larger increases in performance than what current generation has over the GTX580. I don’t feel it’s fair to compare HD7970 to 6970 since AMD raised the price almost $200….
