New GK104 SKU Details Surface

We know from a late-March article that NVIDIA is working on two new SKUs based on its GK104 silicon, for launch in May. With the Kepler architecture, particularly with the design of the new-generation Streaming Multiprocessors (SMX), NVIDIA substantially increased CUDA core density. Each SMX holds 192 CUDA cores, and as with the previous-generation Fermi architecture, the SMX count is the only thing NVIDIA can tinker with, to control CUDA core count in new GPUs. GeForce GTX 680's little brother, hence will have 7 out of 8 SMX units enabled, and end up with a CUDA core count of 1344. This leaves easier to configure parameters such as clock speeds, for NVIDIA to design the perfect SKU to capture a price-point. NVIDIA is targeting the sub-$399 market, while somehow maintaining competitiveness with Radeon HD 7950.



Specifications of the new SKU follow.

GeForce GTX 670 Ti, by the numbers
  • 4 Graphics Processing Cores (GPCs), 7 Streaming Multiprocessors (SMX)
  • 1344 CUDA cores
  • 112 Texture Memory Units (TMUs), 32 Raster Operation Processors (ROPs)
  • 256-bit wide GDDR5 memory interface
  • Around 900 MHz base core clock, boost clock and feature availability not known
  • Around 1250 MHz (5.00 GHz GDDR5 effective) memory clock, around 160 GB/s memory bandwidth
  • Estimated price US $349-399
The new report reinforces the May launch time-frame.Source: VR-Zone

errr i think thats a bit wrong ,should be enabled, ty for the news:)
That would make it as fast as a tricycle:p.

Sweet. Hopefully it can OC to match a 680.

This card might take away the power efficiency crown from Pitcairn.

Gogo competition! The price has stagnated over the past year due to Nvidia's incompetence, now with GK104 things will heat up nicely, hopefully translating to cheaper wares for all:)

Um...math check? I do believe you mean 1250MHz.

Fixed. I relied on Theo's math.

god if this thing is around the price of 350-399 and beats the 7950 and obviously the 7870 it will be so much win.

No mention of how much VRAM. Better be 2GB...

They mention 256bit so it must have 2gb.
I really hope they dont cut down the vrms even further.

They will. If this rest in a real nice spot on the priceboard. AMD will be forced to lower prices if Nvidia takes away customers :D
Might be the first time I might consider going back to the green side if the price/performance is right :)

funny how the 680 was originally named 670 Ti. if it were not for amd, we would have had the 680 today at the 670 Ti price. too bad for us

Yea, I assumed 2GB, but you never know. Stranger things have happened. If I could get a 670 that performs near or at the level of an HD7950 for $350, I'd take the leap. Not sure if I want to wait and see what comes this fall or jump on GK104 though. The GTX680 did impress me quite a bit, just have to see how it scales down.

its for those who can't buy 680 but want to get rid of old cards

God... with all the time Nividia's taking I'd hope so! While you can say in May, by October AMD could have some 8850 that beat that... it's the same thing! This is no longer competition, just you buy what in the market when you need it.

While here's my question... why not sooner? Face it these are from production GK104 wafers, you mean Nividia doesn't have enough chips from those wafer to start production. I understand the GTX680 as it got changed midstream, but these products have been pretty well canned in terms of design and PCB while they've known what they need to beat 2-3 months back in terms of 7890/7950. So it would appear everything shoulds be ready but we wait again? By May they'll have lost any momentum gain by the GTX680 and without SKu's to buy that waning fast.

No no, Nvidia is awesome, it doesn't matter what the timetable is. Any card that marginally beats another card is just awesome.

If the 670Ti will bring a proportional increase in performance over the 570 as the 680 is over the 580 (let's say 30%) at the same pricepoint as the 570 was launched in 2010 then it's not so bad considering that AMD offers 5% increase (7870/7850) for the same price that you could buy in 2010 cards like 6970/6950.

Would there be a sub 200$, 28nm parts from nvidia's side?

There will certainly be. But when?

It's 7 SMX units while the 680 has 8 SMX units, so it's probably around that ballpark of 7/8th's the speed of the 680 (plus adjustments for clock speed and bad silicon and memory). My guess is 7/8ths of the 680 but a similar power envelope, but who knows until we get some numbers.

GK104 is the sub-200$ part but only after it satisfies the needs of early eager adopters and the card is largely unavailable to begin with. I think there should be a 1152 part at GTX570 level of performance just like GTX460 was positioned between 275 and 285, anything below goes to sub 150$ like GTS450.

I imagine the GTX660 will be around $200 or so.
