Think the GTX 1070 is too weak but don't want to pay out for the costly 1080 instead? The GTX 1070 Ti could be the middle ground you're looking for and Nvidia is set to use it to shore up its current line up of Pascal cards ahead of the eventual Volta release which is expected to trounce AMD's Vega competition. While we don't have much in the way of official knowledge of the 1070 Ti yet, we do know what its specifications will be like thanks to a leak.
In terms of its hardware, the 1070 Ti is much closer to the GTX 1080 than its 1070 name sake. It sports the same 16nm process built on the GP104 as both aforementioned cards, but it differs in clock speed and shader count. At the base it shares the same core clock as the GTX 1080 - 1,607MHz - though its boost clock of 1,683MHz is the same as the GTX 1070 (thanks Hexus).
In terms of shader count, it comes with 2,432, which is more than 500 more than the standard 1070 and just 128 less than the GTX 1080. It has 152 texture units, 32 more than the 1070.
It will sport 8GB of GDDR5 memory, with a memory clock of 8Gbps and 256GBps of memory bandwidth. That's where it really falls behind the GTX 1080 - which sports GDDR5X - though the weaker memory is no doubt why the cost of the card is not too exorbitant.
You'll get all of that for the rumoured launch price of $430. That's quite a nice upgrade over the GTX 1070 for just an extra $50 and it represents a big saving over GTX 1080 pricing, which suggests that the 1070 Ti could be the new bang for buck card at the top-end of Nvidia's pricing scale.
Although we don't have a confirmed launch date for the card, it's expected to show up on October 26, which cards shipping out on November 2.
