For those considering the Threadripper 9000 series for CPU-based AI inferencing, there is terrific generational uplift there too. With the AMD Zen 5 cores plus support now for DDR5-6400 memory, Mozilla's LocalScore AI benchmark that leverages Llama.cpp was showing off significant improvements to both performance and power efficiency.

👁 LocalScore benchmark with settings of Model: Qwen2.5-14B-Instruct-Q4_K_M.gguf, Acceleration: CPU. Threadripper 9980X was the fastest.

With the Threadripper 9000 series and their Zen 5 cores having a full 512-bit data path is also helping out a lot for these great generational gains if upgrading from the Ryzen Threadripper 7000 series.
