ASUS AI Intelligence

AI Cache Boost

Supercharge your large language model (LLM) workflows with AI Cache Boost. Exclusive to ASUS AMD 800 and 600 series motherboards that use Ryzen™ 9000 Series CPUs, this BIOS setting optimises CPU cache and memory pathways to deliver up to 29% faster local LLM performance with high-speed memory tuning.

• Increase AI LLM performance up to 29% with AI Cache Boost

Tokens Per Second

With an ASUS AMD 600 or 800 series motherboard and a Ryzen™ 9000 series CPU, you can enable the AI Cache Boost setting in the BIOS. This feature applies comprehensive optimisations to CPU cache and memory pathways, greatly reducing the typical performance drop that can happen when VRAM is used up.

Internal testing determined that enabling AI Cache Boost delivered up to a 15% performance uplift when running large language models that exceeded graphics card memory. With high-speed DDR5 memory and additional Infinity Fabric clock (FLCK) speed tuning, this performance uplift nearly doubled.

For enthusiasts, creators or anyone who wants a powerful AI model capable of deep reasoning and natural conversation running on their own hardware, they can enjoy these uplifts today with AI Cache Boost.
