GeForce GTX 660 Ti Specifications and Launch Date Released

[btarunr]

According to the latest set of specifications scored by SweClockers, NVIDIA's upcoming performance-segment GPU, the GeForce GTX 660 Ti, is not much different from the GTX 670. The GTX 660 Ti is based on the 28 nm GK104 GPU, with 1,344 CUDA cores enabled - the same number as that on the GTX 670. What's more, the clock speeds don't differ between the two, either - 915 MHz core, 980 MHz GPU Boost, and 6.00 GHz GDDR5-effective memory.

The memory amount stays 2 GB, as well. It's just that the memory bus width is reduced from 256-bit to 192-bit, resulting in 25% lower memory bandwidth. The 2 GB of memory is spread across the 192-bit memory bus, probably with four chips using 32-bit wide paths each, with four other chips sharing two 32-bit wide paths. NVIDIA is known for pulling off such memory configurations, like it did with the GeForce GTX 550 Ti.

The other major component of the SweClockers report is the launch date. According to the source, NVIDIA will launch the GeForce GTX 660 Ti on August 16. We predict that the GamesCom event held in Cologne, Germany, which opens to the public on the same day, could serve as a launch-pad.

Many Thanks to NHKS for the tip.

 

[_JP_]

So this will be more like a GTS 670 (or GTX 670 SE)....fine by me.

 

[LTUGamer]

Sounds too good If it is real specs this card will be awesome

 

[Delta6326]

Awesome news I wounder just how much will it be slower than 670 if they only lowered the Bus. 670 uses 225Gb/s

 

[Benetanegia]

If those specs are correct, it's 100% settled for me, GK104 has always been the chip meant for the $300 card. Not that I didn't know that before, but now it's crystal clear, no doubt. Nvidia has always been willling to sell it for $300, except it would have been stupid to do so, when selling it for $500 was possible. But now they are going to finally sell it for $300 and far from crippling it as much as posible they are giving this card every opportunity to succeed even against their own GTX670. At least at anything but 1440/1600p.

 

[Crap Daddy]

Well it's pretty much what was suspected. At 1080p this will be probably 5-8% slower than a 670 and the same percentage faster than the 7950. People will understand why the 7950 has come down as low as just $320 from a launch price of $450 and the 7870 from $350 to $280 in four months. I can't remember such a slash in prices in less than six months. Still, there's no sign of GK106 and a contender for the 7850.

Afaik 670 has 192Gb/s and this will have 144Gb/s, this also must have only 24 rops since its 192bit. At least it will have 2gb.

 

[Disparia]

Nice. Except for the name, which makes me gag just saying it.

Anyone make 4Gb GDDR5? Someone could put out a 3GB No-Sharing Edition.

Well, I was pretty convinced that it would have 1152 SPs and only 1.5GB, and maybe a 25-50 Mhz reduction too. I didn't expect this card to be so close to a 670.

I'm not sure they need a contender for the HD7850 right now. Both 670 and 680 have sold more than the 7850, according to Steam. Which shows that there is market for such prices if the performance/features seem right. The 660 will not have any problem doing the same at its price point. Because, honestly, if all this trns out to be true, look at how much more you will get for $300 compared to a $250 7850. When the 7850 gets the price cut AND if they see their sales are hurt, then they'll release something. Right now it's everything capped at how much TSMC can produce so they are not in a hurry to introduce chips that will eat production time, won't be able to sell much more and would need to be sold for half as much. Bad bussiness in the current situation, they already have all the design wins they want and have nothing to demostrate either, to anyone (partners investors etc must all be extremely happy with 680 and 670 execution) and a $300 card that is within a 5-10% of cards that costed $550 not too long ago it's not going to hurt their mindshare either. The lack of a competing product in the $250 bracket won't hurt them for the time being IMO.

EDIT: BTW, these specs also put the rumors about yields to rest once and for all.

 

[hhumas]

so it will be gtx 670 little brother

What would you say if the're gonna be a 1152 SP part at 250$ based on the same motto "one chip fits all"? The GTX660?

 

[Mals]

Hmm.. As the proud owner of a $400 670, this insults me =P It makes me wonder if I should sell my 670, get SLI 660's and go nuts on BF3 at full settings for 120 fps constantly. I planned on SLIing my 670's in a few months but.. this sort of changes the game. It makes me actually wonder if I should really just wait for GK110 instead.. since, as mentioned before, the GK104 was really meant to be the mid tier card.

Gotta wonder what NVidia is really capable of right now.. even buying a 690 seems silly if they are able to price this GPU at such a low price.

 

[Benetanegia]

I could expect that, after a few more months. Like I said it's clearer than ever that GK104 IS the $300 card chip. And that would have been the full chip, cut down chips would have sold in the $200-300 bracket. So that is still possible and wouldn't be too far from what they did with G92 tbh, where a single chip served a rather large price bracket. But that will happen when they can sell lots and lots of them, when the number of units shipped can justify the reduction in price. Until then I don't expect them to do anything, but TSMC has posted some very positive numbers today/yesterday regarding 28nm ramping up and expect even better numbers the next quarter so this 660 you're speaking about might come close to the Ti version.

BUT they might also simply cut the prices of the 660 and 670 according to competing prodcuts while needed, while retaining the GTX680 at relatively high prices for the few that remain willing to pay for premium cards, it worked with GTX580 after all, it remained (and continued selling) at close to $500 even though the 570 suffered several price cuts. As for 660 and 670, it would be like going with their plan A, which was selling GK104 parts in the $200-$300 price bracket and sell lots and lots of them, like GF104 and GF114 did before.

So yeah either way, I can definitely see GK104 parts selling for $200 in a few months, depending on what AMD does and 28nm ramping up.

Whoops I was looking at an OC 670 GPU-Z screenshot. This maybe my next GPU.

 

[NHKS]

GK104 (1536/8): Tesla K10(x2), GTX 690(x2), GTX 680
GK104 (1344/7): Quadro K5000M, GTX 670, GTX 660Ti, GTX 680M
GK104 (1152/6): GTX 660 (my presumption)
GK104 ( 960/5): Quadro K4000M

phew! talk abt versatility of the GK104..

 

[Nihilus]

So the GTX 660ti vs the 670 will basically be a GTX 560 SE vs. a GTX 560, right? Couldn't find any benchmarks for the 560 se to compare.

 

[dj-electric]

2 Options
1. sweclockers have balls
2. sweclockers are in some kind of agreement.

Now, let us all, who actually have the hardware and can post stuff under "source: sweclockers" post this on our websites so we can spread the word without fearing of being untrustworthy of false information.

"According to the source, NVIDIA will launch the GeForce GTX 660 Ti on August 16"

now, are we forgetting the little brother?

No. I have an SE in my second machine (by the way best bang for buck for mid level card where I live) and it's got 288 SP vs. 336 in the GTX560 while ALSO having 192 bit bus vs. 256 bit.

 

[Xzibit]

The big winner is GameCon

660 Ti & 7990 expected to be debut there.

Hmm.. As the proud owner of a $400 670, this insults me =P It makes me wonder if I should sell my 670,

And why do you think Nividia’s been holding-off (longer) on each release of a GK104? They took whatever limited 680’s they could scavenge and sent them out, those who anted-up felt great. Six weeks pass and 670 releases, and guy’s go wow it’s like a 680 but $100 less "take my money"! Here where it gets controversial Nvidia almost needed to hold out another 13 weeks for their next release. At that point guys who could swing $400 have taken to temptation, while enough time has passed not to feel to jaded. So now a $300 card that’s 5-8% below that, If you buy a 670 now your faux pas, while time has passed so most 670 buyer aren't considering they’ve been played. If you dropped something like $540 back in March some 20 week later, other might be getting 10-12% less performance for 80% less! That’s seems a little wack, but it’s like saying you paid $12 a week for the enjoyment!

Can’t say it’s any better for AMD early adopters, but hey we’ve all seen that scenario play before. However this one kind’ of new different in way, it pays extreme dividends to those who hold-out. I know AMD got caught thinking it would battle the same old way with Nvidia, a GK100 vs. Tahiti on down. Though this time Nvidia gets blessed being able to have one wafer span and extremely diverse price range. They harvest the best for 680’s, nip and tuck the GK104 and get a 670, and now neuter the bandwidth (lower cost) and probably drop the boost feature and they have covered all the bases.

GK104 (1536/8): Tesla K10(x2), GTX 690(x2), GTX 680
GK104 (1344/7): Quadro K5000M, GTX 670, GTX 660Ti, GTX 680M
GK104 (1152/6): GTX 660 (my presumption)
GK104 ( 960/5): Quadro K4000M

phew! talk abt versatility of the GK104..

Good point GK104 wafers are needed like pizza's from a Costco oven. No wonder the slow channel fill.

Ok, Guess the shader loss made the difference and not so much the bandwidth loss. On the other hand, these card are a bit more powerful, so that 192 bit bus may be more of a bottleneck, but we will see. Worst case scenario, it will have a 25% performance loss. Either way, it should make for some great competition to the HD 7870!

If these specs are true then expect better performance than the 7950.

they will, their will also be a special with 256 bit mem bus called the 660 GTUltra

looks good , they have the upper end well sorted , how about sorting the majority out now or is anyone who games going to have to spend new console money for just the graphics card nowadays, i might and you might but most dont my mates dont at all want to pay more then 200 max for gfx and they think thats high end< back in the real world here Beni

so far to me a prior alleged power user who considerred himself an enthusiast, all nvidias cards have been bordering on ridiculous re:: price

 

[refillable]

$350...?
