Performance Analysis
Dense FP16 performance reaches 989 TFLOPS on the H100 and 65 TFLOPS on the T4. This difference means the H100 completes matrix operations in training and inference at a substantially higher rate than the T4. With sparsity the H100 attains 1979 TFLOPS in FP16 while the T4 figure remains at its dense value of 65 TFLOPS. Memory bandwidth of 3350 GB/s on the H100 versus 320 GB/s on the T4 allows larger batch sizes during model execution without frequent data movement stalls. FP32 throughput of 67 TFLOPS on the H100 compared with 8.1 TFLOPS on the T4 further widens the advantage for precision sensitive scientific workloads. The H100 INT8 dense rating of 1979 TOPS exceeds the T4 INT8 dense rating of 130 TOPS by a wide margin.

When to Choose the H100
The H100 suits LLM training scenarios that require 989 TFLOPS dense FP16 throughput and 80 to 94 GB memory capacity. Workloads involving large batch sizes benefit from the 3350 GB/s bandwidth figure. The 700W TDP is acceptable in data centers equipped for high power draw.
When to Choose the T4
The T4 fits inference tasks where 70W TDP and 16 GB memory suffice for smaller models. Its 65 TFLOPS dense FP16 rating supports moderate throughput needs without excessive power consumption. PCIe form factor deployment remains straightforward in standard server configurations.
Use Cases
The H100 supplies 989 TFLOPS dense FP16 and 80 to 94 GB memory that exceed the T4 65 TFLOPS and 16 GB figures.
Dense FP16 performance of 989 TFLOPS on the H100 supports higher throughput than the 65 TFLOPS available on the T4.
The H100 3350 GB/s bandwidth and 1979 TFLOPS dense FP8 rating enable efficient adaptation of models beyond T4 capabilities.
Both GPUs handle image generation yet the H100 989 TFLOPS dense FP16 provides faster iteration while the T4 70W TDP suits lighter deployments.
FP32 throughput of 67 TFLOPS on the H100 surpasses the 8.1 TFLOPS rating of the T4 for compute heavy simulations.
