Intel® Celeron® M 420

The Intel Celeron M 420 is a laptop processor with 1 cores and 1 threads. It launched in Apr 2006. Rated TDP is 27 W.

The Intel Celeron M 420 scores 391 in single-core performance and 139 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 233 for overall performance, 638 for productivity performance, 780 for creator performance, 127 for engineering performance and 1,208 for gaming performance. Its multi-core throughput works out to 139 per core, 139 per thread and 5 per watt. Its computed efficiency index is 45. Its performance index is 3, so its overall performance is 97% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Workload sub-scores (integer math, floating point, compression, encryption, physics, SIMD, prime sieve and sorting) are not recorded for the Intel Celeron M 420.

The Intel Celeron M 420 has 1 physical core and runs 1 logical thread. It does not use a hybrid performance and efficiency core layout. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 1.60 GHz.

The Intel Celeron M 420 is a laptop processor and belongs to the Intel Celeron family. It launched in Apr 2006.

The Intel Celeron M 420 has 64 KB of L1 cache and 1 MB of L2 cache. That adds up to about 1.1 MB of cache, or 1.06 MB per core. Each core has 1 MB of private L2 cache.

The Intel Celeron M 420 has a 2-level cache hierarchy: L1 at 64 KB and L2 at 1 MB. L2 is the largest level and makes up about 94% of the cache listed here.

The Intel Celeron M 420 has a rated TDP of 27 W.
