Performance Analysis
The H100 NVL delivers FP16 dense performance of 989 TFLOPS compared with the L4 FP16 dense performance of 121 TFLOPS, producing an eightfold advantage that shortens training iterations for large models. FP32 throughput stands at 67 TFLOPS for the H100 NVL against 30.3 TFLOPS for the L4, which directly affects precision-sensitive scientific simulations. Memory bandwidth of 3350 GB/s on the H100 NVL versus 300 GB/s on the L4 permits substantially larger batch sizes during both training and inference without frequent host transfers.

When to Choose the H100 NVL
The H100 NVL suits workloads that require the 94 GB HBM3 capacity and 3350 GB/s bandwidth to hold entire large language models in memory. Its 989 TFLOPS FP16 dense rating accelerates distributed training sessions that benefit from the NVLink bridge interconnect.
When to Choose the L4
The L4 fits inference pipelines and fine-tuning tasks where the 72 W TDP and 24 GB GDDR6 configuration keep operating costs low while still providing 121 TFLOPS FP16 dense throughput. Its PCIe 4.0 interface integrates easily into standard servers without additional bridging hardware.
Use Cases
The H100 NVL supplies 94 GB HBM3 and 989 TFLOPS FP16 dense that accommodate full-scale model training runs.
Its 3350 GB/s bandwidth and 1979 TFLOPS FP8 dense rating support high-throughput serving of large models.
Both GPUs handle parameter updates yet the L4 72 W TDP suits smaller clusters while the H100 NVL accelerates larger batches.
The L4 24 GB GDDR6 and 242 TFLOPS FP16 dense rating meet typical image generation memory needs at lower power.
The H100 NVL 67 TFLOPS FP32 rating and 94 GB capacity accelerate double-precision workloads that exceed 24 GB.
