English(EN) R9V: A designer set of kernels I've been working on for R9700s/RDNA4. Qwen3.8-Flash-Next Unsloth IQ4_XS (w/ TP on 2 R9700s, MTP, SSD n-gram, 128k ctx, vision): TG256 of *78 tok/s* (~3x increase), PP8192 of *1510 tok/s* (~30x increase).

自定义 RDNA4 内核将 Qwen3.8 性能提升高达 30 倍

一位开发者创建了一套名为 R9V 的自定义内核,旨在优化 RDNA4 显卡的性能,特别是针对 AMD 的 R9700s。当应用于 vLLM-Radiance 推理引擎时,这些内核显著提高了 Qwen3.8-Flash-Next 等模型的速度,在某些任务中实现了高达 30 倍的性能提升。该项目还包括为密集模型开发的独立推理引擎,并提供了 Qwen3.8-Flash-Next 和 Muse Glimmer 30B 的软件包,并与 llama.cpp 等其他后端进行了性能比较。 AI

影响RDNA4 硬件的优化可能有助于 AMD GPU 更广泛地采用本地 LLM。
