Quote:Courtesy of the team at Tech ARP (via Hexus), we have a list of specs that was apparently confirmed by the product page posted by KFA2. The GTX 1070 Ti will almost certainly use a less-neutered version of the GP104 GPU that underpins the GTX 1070 and GTX 1080.
Of the 20 Pascal streaming multiprocessors on board GP104, the GTX 1070 Ti will purportedly have 19 of them active, for a total of 2432 shader processors, 152 texture units, and 64 ROPs. Those figures are only slightly behind the resources of the GTX 1080's, so the GTX 1070 Ti might sit uncomfortably close to that card in Nvidia's product stack (at least reference clock for reference clock). We'll see just how close in a moment.
The biggest difference between the GTX 1070 Ti and GTX 1080 will apparently be in the lesser card's memory subsystem. Where the GTX 1080 uses 8 GB of GDDR5X RAM clocked at 10 GT/s or 11 GT/s, the hypothetical GTX 1070 Ti might stick with 8 GB of GDDR5 RAM running at 8 GT/s. That means the pumped-up GTX 1070 could offer just 256 GB/s of memory bandwidth, down substantially from the GTX 1080's 320 GB/s at reference speeds.
The beefed-up GTX 1070 Ti doesn't gain any extra pixel fill rate compared to its less-shiny forebear, but its peak texturing and compute capabilities make it a better match for the RX Vega 56. The green team doesn't seem willing to let its competitor hold even a dead heat in the graphics-card horse race, it seems. It'll remain to be seen how Nvidia manages to keep the GTX 1070 Ti from cannibalizing GTX 1080 sales, though, given how closely-matched the cards are in almost every measure of theoretical performance we can bring to bear.
