Measured comparison
| Metric | SK hynix fastlött DDR4-3200 2×16 GB SO-DIMM | SK hynix DDR5-5600 1×16 GB SO-DIMM (OEM) |
|---|---|---|
| RAM score (the kit's own performance: bandwidth + latency) | 6,044 | 4,499 |
| Best rig (GAMING — whole PC) | 3,675 | 2,402 |
| Bandwidth, one thread | 16,136 MB/s | 11,655 MB/s |
| RAM latency (lower is better) | 117.5 ns | 153.2 ns |
| Rated speed | 3,200 MT/s | 5,600 MT/s |
| Runs at (seen, avg) | 3,200 MT/s | 4,800 MT/s |
| Capacity | 32 GB | 16 GB |
What the numbers mean
The RAM score is the kit's measured performance in the rigs it sat in — single-thread bandwidth and latency beyond L3. Platform, BIOS settings and whether XMP/EXPO was on all affect it. GAMING is the whole rig's score. We show both and never mix them.
All numbers come from our benchmark suite, the same test on every PC, written in Rust with no middleware. The methodology is open at https://whatfps.com/metodik
