Comparing the 5090 to the 4090 and B200: How Does It Stack Up?

The benchmark of Nvidia's Blackwell architecture GPUs, specifically the B200 and RTX 5090 models, uses Qwen2.5-Coder-7B-Instruct to evaluate performance across various sequence lengths and batch sizes, which reflect real-world LLM inference scenarios. The analysis highlights the RTX 5090's superior performance for longer sequences and higher batch processing, making it cost-efficient for large-scale operations despite its higher price per second. In contrast, the RTX 4090 offers a better cost-performance balance for shorter sequences and customer support applications. For extensive document analysis, the B200 proves most effective due to its substantial memory capacity, significantly reducing processing time and costs. The choice of GPU thus depends on specific workload demands, with the B200 recommended for enterprises seeking maximum throughput and future growth accommodation.
