Performance Analysis
The FP16 dense performance reaches 989 TFLOPS on the H200 and 1307.4 TFLOPS on the MI300X. This gap indicates the MI300X can process larger batches during training or inference steps that rely on dense FP16 operations. The FP32 rating stands at 67 TFLOPS for the H200 and 163.4 TFLOPS for the MI300X so workloads using full precision arithmetic complete more operations per second on the MI300X. Memory bandwidth of 4800 GB/s on the H200 versus 5300 GB/s on the MI300X affects the size of data batches that fit within transfer limits during model execution. Direct comparison of dense FP16 figures shows the MI300X ahead while the same holds for sparse FP16 ratings of 1979 TFLOPS on the H200 against 2614.9 TFLOPS on the MI300X.

When to Choose the H200
The H200 suits environments that prioritize 700W TDP operation and NVLink interconnect availability. Its SXM and NVL form factors align with systems already configured for those interfaces while the 4800 GB/s bandwidth supports steady data movement in dense FP16 tasks rated at 989 TFLOPS.
When to Choose the MI300X
The MI300X fits scenarios that require 192 GB memory capacity and 5300 GB/s bandwidth for handling larger working sets. Its 1307.4 TFLOPS dense FP16 rating and 163.4 TFLOPS FP32 rating provide advantages in throughput for training or inference steps that scale with those metrics.
Use Cases
The MI300X supplies 192 GB memory and 1307.4 TFLOPS dense FP16 which exceed the 141 GB and 989 TFLOPS on the H200.
The MI300X offers 5300 GB/s bandwidth and 2614.9 TFLOPS FP8 dense which support higher throughput than the 4800 GB/s and 1979 TFLOPS on the H200.
Both GPUs deliver comparable FP16 dense ratings relative to their memory sizes of 141 GB on the H200 and 192 GB on the MI300X.
The MI300X provides 163.4 TFLOPS FP32 and 5300 GB/s bandwidth which aid image generation steps more than the 67 TFLOPS and 4800 GB/s on the H200.
The MI300X achieves 163.4 TFLOPS FP32 compared to 67 TFLOPS on the H200 for precision heavy calculations.
