Positions in all rankings

Common positions AMD Ryzen 9 9955HX CPU in popular benchmarks, for comparison with other models.

No data

Blender Open Data

Official median of community submissions; higher is better. Blender versions, operating systems and compute backends remain separate.

Blender 5.2.0 / CPU / Windows: 639.217707 samples/min submissions: 20; snapshot: 2026-09-30 Official source

Snapshot date is the retrieval date, not the measurement date. Individual dates, RAM, drivers and power limits are unknown. This aggregates different user systems; it is not a test of a specific partner board and is excluded from the legacy composite index.

Benchmarks

Performance tests CPU

No comparable legacy benchmark results are available.

These are saved results from the earlier catalog. Measurement dates and test configurations were not recorded. Models with no comparable results are omitted.

Recent models: test results with identified primary sources — Cinebench R23 · Cinebench R20 · Cinebench R15 · Cinebench 2026 · RandomX benchmark

Comparable benchmark results are required to suggest performance alternatives.

PL1 is the sustained processor power limit; PL2 is the short-term turbo power limit. They are not measured performance or efficiency.

The values are used to select the optimal cooling system and power supply.
