NVIDIA GeForce RTX 3080 12GB
Overview
The 12 GB GeForce RTX 3080 is the larger of the two GA102 bins NVIDIA sold under the RTX 3080 name, and the more useful of the pair for local AI work: 12 GB of GDDR6X on a full 384-bit bus rather than 10 GB on 320-bit, and 70 streaming multiprocessors rather than 68. The extra two gigabytes are what decide whether a 7B model fits in half precision without offloading, which is why second-hand 12 GB cards still command a premium over the 10 GB version. Tensor throughput follows the GeForce GA10x pattern: TF32 runs at the plain FP32 shader rate rather than the doubled rate professional Ampere cards get, while INT8 and INT4 are left at full speed, so this is a strong quantised-inference card and an ordinary TF32 training one. There is no ECC and no NVLink on this bin.

FP8 | No verified data available | The part supports 2:4 sparsity, but the vendor publishes no sparse figure for this precision |
FP6 | No verified data available | The part supports 2:4 sparsity, but the vendor publishes no sparse figure for this precision |
FP4 | No verified data available | The part supports 2:4 sparsity, but the vendor publishes no sparse figure for this precision |
INT8 8-bit integer | 245TOPS | 490TOPS |
INT4 4-bit integer | 490TOPS | 981TOPS |
Per watt divides the dense figure by the 350 W board power. Where only a sparse figure exists, the cell says so.
