Intel® Celeron® U3400

The Intel Celeron U3400 is a laptop processor with 2 cores and 2 threads. It launched in May 2010. A 2-MB L3 cache backs the cores (1.6 MB per core). It supports DDR3 memory. It uses the FCBGA1288 socket. Rated TDP is 18 W.

The Intel Celeron U3400 scores 456 in single-core performance and 516 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 485 for overall performance, 974 for productivity performance, 1,105 for creator performance, 481 for engineering performance and 1,497 for gaming performance. Its multi-core throughput works out to 258 per core, 258 per thread and 29 per watt. Its computed efficiency index is 114. Its performance index is 6, so its overall performance is 94% 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.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Celeron U3400 scores 2,009 in integer math, 1,210 in floating-point math, 9,867 in compression, 114 in cryptography, 82 in physics simulation, 374 in vector SIMD, 5 in the prime sieve and 1,272 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 97% below in integer math, 97% below in floating-point math, 96% below in compression, 99% below in cryptography, 92% below in physics simulation, 98% below in vector SIMD, 93% below in the prime sieve and 94% below in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Celeron U3400 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 U3400 is a laptop processor and belongs to the Intel Celeron family. It launched in May 2010.

The Intel Celeron U3400 has 256 KB of L1 cache, 1 MB of L2 cache and 2 MB of L3 cache. That adds up to about 3.3 MB of cache, or 1.63 MB per core.

The Intel Celeron U3400 has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 2 MB. L3 is the largest level and makes up about 62% of the cache listed here.

The Intel Celeron U3400 supports DDR3 memory and runs memory at up to 800 MT/s. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Celeron U3400 uses the FCBGA1288 socket.

The Intel Celeron U3400 has a rated TDP of 18 W.
