Corsair CMSX16GX5M1A5600C48 2×16 GB

Measured performance for Corsair CMSX16GX5M1A5600C48 2×16 GB across 24 verified WhatFPS runs. Every number is measured in our benchmark suite — not estimated, not self-reported. RAM score (the kit's own performance: bandwidth + latency): 8,466 in its best run — the best of 2 measured rigs, #57 of 127 measured memory kits. The average over each rig's best run is 8,264. Most often paired with Intel(R) Core(TM) Ultra 9 290HX Plus.

What the numbers mean

The headline score is the part's best measured run, and the measurements under it come from that same run. It shows what the part has been proven to do — not what an average rig gets out of it. The GAMING score is a geometric mean of GPU (63 %), CPU (30 %), RAM (5 %) and drive (2 %) — a weak part cannot hide behind a strong one. The RAM score is a geometric mean of bandwidth and latency. Bandwidth is measured on ONE thread — a single core cannot saturate two memory channels, so the measurement cannot see channels and we claim nothing about them. Latency is a pointer chase in a buffer four times larger than L3. The score is measured on the whole configuration: a kit running below its rated speed (XMP/EXPO off) gets the score the rig actually delivered. Every run is HMAC-signed in the app and scored on the server. The full methodology is open at https://whatfps.com/metodik
