The Turing Block Diagrams

In chapter of this architecture review, I like to chart up and present to you the separated GPU block diagrams. Mind you that the specification on the 2080 and 2080 Ti differ slightly compared to the fully enabled GPU, as the GPUs have disabled shader / RT /Tensor partitions. So the block diagrams you see here as based upon the fully enabled GPUs. Only the GeForce RTX 2070 is a fully enabled TU106 chip.
