MI250X vs V100

The MI250X delivers 383 TFLOPS dense FP16 while the V100 delivers 125 TFLOPS dense FP16. This ratio indicates that the MI250X can complete dense FP16 matrix operations more than three times faster than the V100 for training or inference steps that remain within dense arithmetic. The MI250X also supplies 47.9 TFLOPS FP32 against the V100 15.7 TFLOPS FP32, preserving a similar ratio for single precision workloads. Memory bandwidth of 3277 GB/s on the MI250X versus 900 GB/s on the V100 permits larger batch sizes before memory stalls occur during data movement. The 128 GB VRAM capacity on the MI250X further supports models that exceed the 32 GB limit of the V100 without requiring model parallelism across multiple devices.

Its 383 TFLOPS dense FP16 rating also accelerates dense matrix workloads that fit within the higher power envelope of 560 W. Organizations that already operate Infinity Fabric fabrics gain additional interconnect compatibility with the MI250X.

The V100 fits deployments constrained to 300 W TDP or existing PCIe 3.0 and NVLink infrastructures. Its 15.7 TFLOPS FP32 rating remains adequate for smaller scientific computing jobs that do not require the 128 GB capacity of newer cards. The dual form factor options of SXM2 and PCIe allow installation in a wider range of legacy server chassis.
