And the newer GTX 1080 AIB GP104 newest binns are probably now overclocking higher on those AIB SKUs and still making Nvidia more money.
Nvidia can still sell Pascal/GP104 new bins(1070ti) using mostly DX11 benchmarks and not cannibalise the GTX 1080 AIB SKU sales at all until Volta is needed to compete with any RX Vega refreshes that will arrive in 2018. This GP104/1070ti binning process targeted shader counts that where just enough for those DX11 titles that are still more abundent than the DX12/Vulkan titles where Vega 56 may compete with even the GTX 1080 under the new graphics APIs.
And Nvidia’s binning process mamagement software was loaded with every one of those dies’ working shader counts to give Nvidia a complete statistical range of shader counts with which to effectively allow Nvidia to decide on the exact necessary numbers of shaders for the GXT 1070Ti to perform better than the Vega 56 on average. Nvidia probably held back these dies for months before Vega 64 and 56 arrived and instead of binning them father down to a GTX 1070 Nvidia let these stocks of binned dies that just barely missed having the GTX 1080’s complement of working shaders build up. And TSMC’s wafer production for the best binned GTX 1080 grade dies can probably get a little better overclocks for Nvidia’s AIB partners so it’s just extra gravy for Nvidia’s Thanksgiving before the Volta micro-arch GV104 dies are needed in 2018. Now Nvidia can sell out more GP104 based dies within the RX 56 performance range without having to price cut the GTX 1080 at all. So Nvidia spins up a GTX 1070Ti on the binned dies that at least have close to the GTX 1080’s number of shaders for Nvidia to make the GTX 1070Ti’s shader count. Nvidia is getting every last bit of revenue out of those extra Pascal shaders as it can on those GP104 dies that came off the diffusion lines at TSMC with not enough working shaders to become at least a GTX 1080.
Hardware Canucks saw 2088MHz when they overclocked as well as memory of 8.9Gbps which pushed the performance past the reference GTX 1080 in many games. With the push of two buttons Ryan was able to hit 1987 MHz which surpasses your average GTX 1080 by a fair margin. It should come as no surprise to anyone how the GTX 1070 Ti performs, better than a GTX 1070 but not quite as fast as a GTX 1080 … unless you overclock.
