B200 SXM vs RTX 2080

BlackwellvsTuringUpdated 35 days ago

The B200 emerges as the clear winner for AI and compute-intensive tasks: 4500 TFLOPS FP16 and 192 GB VRAM enable workloads infeasible on RTX 2080's 10.1 TFLOPS and 8-11 GB limits. Despite higher $4.60 per hour average pricing, performance gains dominate modern use cases like LLM training.

Performance Analysis

The B200's FP16 throughput of 4500 TFLOPS vastly outpaces the RTX 2080's 10.1 TFLOPS: this enables training massive neural networks in hours rather than days on the older card. FP32 performance shows a narrower 90 TFLOPS versus 10.1 TFLOPS gap, but the B200's tensor core optimizations favor mixed-precision training common in deep learning. Inference benefits similarly, with FP8 at 9000 TFLOPS on B200 accelerating low-precision deployments impossible at scale on RTX 2080.

Memory specs transform real-world usage: 192 GB HBM3e on B200 supports batch sizes for models exceeding 100 billion parameters, while 8-11 GB GDDR6 on RTX 2080 limits to small models or heavy quantization. Bandwidth of 8000 GB/s versus 616 GB/s reduces data bottlenecks, speeding iterations by orders of magnitude. TDP differences, 1000W for B200 and 215W for RTX 2080, reflect power scaling for datacenter clusters versus single-node efficiency.

When to Choose the B200 SXM

Opt for the B200 in large-scale AI training or inference: its 192 GB VRAM handles trillion-parameter models, and 4500 TFLOPS FP16 throughput cuts training times dramatically. Datacenter environments with NVLink, PCIe 6.0, and InfiniBand interconnects maximize multi-GPU scaling unavailable on RTX 2080. Cloud deployments at $1.71 per hour justify costs for production workloads demanding peak performance.

When to Choose the RTX 2080

Select the RTX 2080 for budget-conscious prototyping or gaming: at $0.05 per hour, it delivers 10.1 TFLOPS FP32 for lightweight inference on models under 7 billion parameters. Its 215W TDP and PCIe form factor suit edge devices or small-scale fine-tuning where 8-11 GB VRAM suffices. Legacy Turing compatibility aids quick tests without high power or interconnect needs.

Use Cases

LLM Training
B200 SXM

B200's 192 GB VRAM and 4500 TFLOPS FP16 support massive models and large batches. RTX 2080's 8-11 GB VRAM cannot handle such scales.

LLM Inference
B200 SXM

9000 TFLOPS FP8 on B200 accelerates high-throughput serving. RTX 2080's 10.1 TFLOPS FP16 limits to small models only.

Fine-tuning
B200 SXM

90 TFLOPS FP32 and 8000 GB/s bandwidth on B200 speed iterations on large datasets. RTX 2080 struggles with memory constraints.

Stable Diffusion
Either

RTX 2080's 10.1 TFLOPS suffices for basic image generation at low cost. B200 excels for high-resolution or batched production.

Scientific Computing
B200 SXM

B200's 192 GB VRAM fits complex simulations; 8000 GB/s bandwidth handles data-intensive HPC. RTX 2080 limits to modest problems.
