llama.cpp b9455 Finally Caught vLLM: 70t/s on 2x3090 Qwen 27B UQ8
A Reddit user has reported impressive performance metrics for the llama.cpp build b9455, achieving 70 tokens per second on dual RTX 3090 GPUs. This marks a significant improvement over the previous vLLM, which dominated multi-GPU inference but had slower speeds. The new build's tensor parallelism allows for more efficient processing, making it a viable option for users previously reliant on vLLM.
- ▪The llama.cpp build b9455 achieved 70 tokens per second on a dual RTX 3090 setup.
- ▪Prior to this, vLLM was the leading choice for multi-GPU inference with speeds of 70+ tokens per second.
- ▪The new tensor parallelism feature in llama.cpp allows for simultaneous processing across GPUs, improving overall performance.
