Arc Pro B70 Trails RTX 3090 in llama.cpp Benchmarks
💡Intel Arc Pro B70 benchmarks reveal gaps and SYCL wins vs RTX 3090 for llama.cpp
⚡ 30-Second TL;DR
What Changed
Arc Pro B70 Vulkan averages -71.1% prompt processing vs RTX 3090
Why It Matters
Highlights Intel Arc as viable but slower alternative to Nvidia for local LLM inference, with SYCL offering gains. Encourages testing Intel hardware for cost-sensitive setups. May accelerate Arc driver optimizations for AI workloads.
What To Do Next
Run llama-bench on your Arc GPU with Vulkan and SYCL to compare inference speeds.
