NVIDIA GeForce GTX 1070 Ti Specs Leaked
TechARP obtained leaked specifications of the NVIDIA GeForce GTX 1070 Ti, which is being launching October 26 and available (supposedly) November 2. While the cards will carry a suggested retail price of $429 USD, which incidentally is higher than the Radeon RX Vega 56, it is anyone's guess what they will actually retail at if miners take an interest in the card.
As anticipated, only one of "GP104" Pascal's twenty streaming multiprocessors is being disabled, which means the GTX 1070 Ti will have 2432 CUDA cores, along with 152 TMUs and 64 ROPs. Core clock speed is being raised to 1607 MHz, unfortunately the boost speed (1683 MHz) is identical to that of the GTX 1070. The increased performance comes not surprisingly with a higher TDP (180 W), which is the same as the GTX 1080. All of which points to performance very close to the existing GeForce GTX 1080. And, if you are wondering how the GTX 1070 Ti stacks up against Radeon's RX Vega, TechARP prepared a chart of that as well:

256 vs 320 is huge
1070TI might have only 80% of the 1080s memory bandwidth but generally speaking a 10-19% OC on GDDR5 is the normal range. at which point memory bandwidth issue becomes pointless.
The loss in shaders is not relative to the loss in bandwidth on this card. The 660ti had a similar issue and that wasn't fine wine.
GTX 1070 best case scenario with GDDR5 hits around 310-320 GB/s thats about 10 GB/s Bandwidth short of a reference 1080.
Looking at W1zzards review, of the MSI 1080 GDDR5x Gaming Plus a 5% clock speed bump and 10% higher memory resulted in a 7-11% performance gain.
Judging by the OC numbers the gains, Nvidia' GPUs on average still scale better with GPU clock than Memory clock. Considering the 1070 Ti features just shy of a 1080s core count and with an OC on the memory bringing it withing spitting distance of the 1080 as well. It goes without saying this 1070 Ti will function 98% like a GTX 1080 but for less money. Considering overclocked 1070s already rival or beat a stock 1080 this is pretty much a no brainer.
That said when Nvidia does stuff like this its the end of that GPU cycle. This model will have a shorter lifespan simply because new GPUs will replace it. While the 1070 and 1080 have been around for ages the 1070 Ti will be around for 6 months or so before we all hunker down and wait for the next gen.
On top of that due to the cut down nature of the GPU its likely making better use of defective dies instead of being a 1070 they can make a 1070Ti jack up the price and reuse defective dies and make a larger profit. They will likely let 1080 stock dry up while the 1070 Ti takes its place.
GTX 1070 Ti and GTX 1080 Ti will be good enough to see NVIDIA through until Volta's launch, plus EOL'ing 1070 and 1080 will allow partner inventories to draw down so that they won't have a glut of cards to dispose of when Volta arrives.
This card really caters as a stopgap 60fps 1440p card to fill the 30% gap between 1070 and 1080. Which means that if you buy it for that purpose, in a year you'll have 50 fps on recent games.
Just have to wait for the reviews but thus far I have been pretty accurate guessing next gen GPU performance so I am interested to see if that continues.
Now yeah the prices are still kinda fucked with the NVIDIA cards all priced near each other.
Cheapest 1070 is around $390
Cheapest 1080 is around $490
Cheapest 1080 Ti is around $715
when the price difference was $200 the 1070 made sense you could OC it and get 1080 stock performance for a whole lot less. Now with the prices being so close the extra 20% in terms of money spent directly gives a buyer 20%+ more performance when OC is taken into account.
Previous the 1070 was the better buy now that situation has reversed. 1070 Ti will likely split the difference. What everyone forget is GPU VRAM saw a price hike due to shortages. My guess is GDDR5 is far cheaper than GDDR5x so NVIDIA and its 1070Ti are basically just 1080 core with 1070 memory. To make a cheaper GPU which then undercuts the Vega 56 and Vega 64 by offering performance in the middle while being far cheaper to produce.
Such a small gap there 1070-1080... from below 60 fps to avg 65. Like I said, if you start reducing the 1080 in some way, it'll rapidly fall below the experience you bought it for and becomes a 'good card for 1080p'.
