The 1080 and the rumored 3080 are not the same architecture: they didn't just get die shrunk.
For the same number of SMs, you're also paying substantial area for the tensor cores, ray tracing acceleration, independent thread scheduling, different I/O to support memory technologies, more NV link, larger caches, etc. That stuff didn't happen for free.
A simply die shrunk 1080 would have had more TFlops than what we have, but it wouldn't be as interesting of a product.
- Simon321 6y agoExactly, the reason for this is that it is an RTX and it has a lot of tensor cores and ray tracing cores which you won't measure by looking at the amount of FLOPS.
