Performance Analysis
The MI300X delivers 1307.4 TFLOPS in dense FP16 compared with 40.3 TFLOPS dense FP16 on the RTX 2080 Ti. This gap means the MI300X processes larger matrix operations in training workloads at higher throughput while the RTX 2080 Ti remains limited to smaller batch sizes. Memory bandwidth of 5300 GB/s shared across MI300X variants versus 448 GB/s shared across RTX 2080 variants further restricts the RTX 2080 Ti when handling large tensors. FP32 performance stands at 163.4 TFLOPS for the MI300X family against 10 TFLOPS for the RTX 2080 family. The MI300X also lists 2614.9 TFLOPS with sparsity in FP16 while the RTX 2080 Ti provides no sparsity figure for FP16.
