AMD has provided benchmarks of its flagship RX 7900 XTX going head to head against the Nvidia RTX 4090 and RTX 4080 Super with DeepSeek's AI model. According to David McAfee on X, the RDNA3-based GPU outperformed the RTX 4090 by up to 13% and the RTX 4080 Super by up to 34%.
AMD tested the three GPUs with multiple LLMs and various parameters using DeepSeek R1. The RX 7900 XTX saw its biggest victory against the RTX 4090 using DeepSeek R1 Distill Qwen 7B, where it outperformed the Ada Lovelace GPU by 13%. AMD also tested three other LLM configurations against the RTX 4090. The RX 7900 XTX outperformed the RX 4090 in two of the three configurations — it was 11% faster using Distill Llama 8B and 2% faster using Distill Qwen 14B. The RX 4090 was 4% faster than the RX 7900 XTX in one configuration, using Distill Qwen 32B.
