Intel® Celeron® U3405

The Intel Celeron U3405 is a laptop processor with 2 cores and 2 threads. It launched in Aug 2010. A 2-MB L3 cache backs the cores (1.0 MB per core). It supports DDR3 memory. It uses the FCBGA1288 socket. Rated TDP is 18 W.

The Intel Celeron U3405 scores 446 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 415 for engineering performance. Its multi-core throughput works out to 223 per core, 223 per thread and 25 per watt. 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 U3405.

The Intel Celeron U3405 has 2 physical cores and runs 2 logical threads. 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 1.07 GHz.

The Intel Celeron U3405 is a laptop processor and belongs to the Intel Celeron family. It launched in Aug 2010.

The Intel Celeron U3405 has 2 MB of L3 cache. That adds up to about 2.0 MB of cache, or 1.00 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Celeron U3405 supports DDR3 memory and runs memory at up to 1,066 MT/s. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Celeron U3405 uses the FCBGA1288 socket.

The Intel Celeron U3405 has a rated TDP of 18 W.
