I swapped the ram in my AMD 7640U Framework 13 from CL46 Crucial to CL40 Kingston Fury memory and benchmarked the difference. I used a simple bash script calling vkmark, glmark2, sysbench and cryptsetup benchmark on Arch Linux running the linux-mainline kernel (6.14.0-1-mainline) and vulkan-radeon (Mesa 25.0.2-arch1.2).
Summary of differences:
sysbench cpu multi-core came out 1% faster with CL40 over 3 runs.sysbench cpu single-core was too close to call.sysbench mem transfer speed was too close to call.cryptsetup benchmark was 3% faster with CL40 over 3 runs.glmark2 was 2.2% faster with CL40 over 5 runs.vkmark was 3.7% faster with CL40 over 5 runs.
I’ll reply with the script and raw results.
