GeForce RTX 2080
Unlike the flagship RTX 2080 Ti, which is based on the TU102 chip, which is unprecedentedly large by consumer graphics card standards, the TU104 GPU at the heart of the RTX 2080 has a close counterpart among Pascal chips, namely the GP102.
A complete TU104 chip contains six Graphics Processing Clusters (GPCs), each containing four Texture Processing Clusters (TPCs) consisting of one PolyMorph Engine and a pair of SM multiprocessors. Accordingly, each SM consists of: 64 CUDA cores, 256 KB of register memory and 96 KB of configurable L1 cache and shared memory, as well as four TMU texturing units.
For hardware ray tracing needs, each SM also has one RT core. A total of 48 SM multiprocessors, the same number of RT cores, 3072 CUDA cores, and 384 tensor cores are obtained in a complete chip. The GeForce RTX 2080 is based on a stripped-down version of the chip with two hardware disabled SM blocks. Accordingly, 2944 CUDA cores, 46 RT cores, 368 tensor cores and 184 TMU texturing units remained active in it.
