Performance Analysis
The H100 SXM5 vastly outpaces the RTX 2080 Ti in compute performance: 1979 TFLOPS FP16 versus 10.1 TFLOPS enables training large neural networks up to 196 times faster. FP32 performance reaches 67 TFLOPS on H100 SXM5 against 10.1 TFLOPS on RTX 2080 Ti, benefiting scientific simulations and general compute tasks. FP8 at 3958 TFLOPS on H100 SXM5 accelerates quantized inference for LLMs, a capability absent in the older Turing GPU. Memory differences prove critical: 3350 GB/s bandwidth on H100 SXM5 supports massive batch sizes for models exceeding 80 GB VRAM, while 616 GB/s and 11 GB on RTX 2080 Ti limit it to smaller datasets prone to out-of-memory errors. In training scenarios, the H100 SXM5 handles full precision workflows efficiently; inference benefits from its FP8 tensor cores for low-latency serving. Power draw underscores trade-offs: 700W TDP for H100 SXM5 demands robust cooling versus 215W for RTX 2080 Ti.

When to Choose the H100 SXM5
Choose the H100 SXM5 for large-scale AI training and inference where 80 to 94 GB HBM3 VRAM accommodates billion-parameter models. Its 1979 TFLOPS FP16 and 3958 TFLOPS FP8 deliver throughput unattainable on consumer hardware, ideal for enterprise deployments. High interconnects like NVLink and InfiniBand enable multi-GPU scaling across clusters.
When to Choose the RTX 2080 Ti
Opt for the RTX 2080 Ti in cost-sensitive prototyping or gaming workloads at $0.06 per hour starting price. Its 11 GB GDDR6 suffices for small model fine-tuning or Stable Diffusion at 10.1 TFLOPS FP16. Low 215W TDP fits edge or desktop setups without datacenter infrastructure.
Use Cases
H100 SXM5's 80 to 94 GB VRAM and 1979 TFLOPS FP16 handle massive LLMs without splitting, unlike RTX 2080 Ti's 11 GB limit.
3958 TFLOPS FP8 on H100 SXM5 accelerates high-throughput serving of large models; RTX 2080 Ti's 10.1 TFLOPS FP16 cannot match latency or scale.
67 TFLOPS FP32 and 3350 GB/s bandwidth on H100 SXM5 support efficient fine-tuning of models over 11 GB; RTX 2080 Ti restricts batch sizes.
RTX 2080 Ti generates images adequately at 10.1 TFLOPS for standard resolutions; H100 SXM5 excels in high-resolution or batched production with 80 GB VRAM.
H100 SXM5's 67 TFLOPS FP32 outperforms RTX 2080 Ti's 10.1 TFLOPS for simulations; NVLink interconnect aids multi-GPU parallelism.
