AMD says new EXPO ‘Ultra Low Latency’ DDR5 memory should be 'effectively the same price' as current kits — feature will work on existing chipsets, but will require new DIMMs

AMD announced EXPO Ultra Low Latency at Computex 2026, but provided very few details about what it is or how it works. The company claims it provides a 13% average uplift compared to JEDEC standards, and a 4% uplift compared to standard EXPO, and that’s it’s coming from leading memory partners. Now, AMD’s David McAfee, VP and general manager of Ryzen and Radeon, has given Tom’s Hardware a bit more color on what exactly EXPO ULL is and how it will roll out.

“Expo has evolved, and we've been working with all of the module vendors. We've seen an opportunity with adding more sub timings to the SPD profile, and just getting a little bit lower latency,” McAfee told Tom’s Hardware.
