A performance comparison between the RTX 3090 and A100 GPUs for running a 7B parameter model using vLLM reveals that the cost-effectiveness depends on the required answer speed and concurrent request load. While the RTX 3090 is cheaper per output token at lower loads and longer answer times, the A100 becomes significantly more cost-efficient when faster response times are critical, even at higher concurrent loads. The analysis highlights that simply comparing hourly rental prices is insufficient for determining the optimal GPU, as throughput and latency requirements must also be considered. AI
