Posizioni in tutte le classifiche

Posizioni comuni Intel Core i9-12900K CPU in benchmark popolari, per un confronto con altri modelli.

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: 334.268413 samples/min submissions: 8; 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.

Benchmark (test)

Test di performance 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.

I valori sono utilizzati per selezionare il sistema di raffreddamento e l'alimentazione ottimale.
