Intel® Xeon™ L3406

The Intel Xeon L3406 is a server processor with 2 cores and 4 threads. It launched in Mar 2010. Clocks run from 2.27 GHz base to 2.53 GHz boost. A 4-MB L3 cache backs the cores (2.6 MB per core). It supports DDR3 memory. It uses the FCLGA1156 socket. Rated TDP is 30 W.

The Intel Xeon L3406 scores 760 in single-core performance and 1,104 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 916 for overall performance, 1,782 for productivity performance, 1,975 for creator performance, 1,028 for engineering performance and 2,556 for gaming performance. Its multi-core throughput works out to 552 per core, 276 per thread and 37 per watt. Its computed efficiency index is 167. Its performance index is 11, so its overall performance is 89% 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 Xeon L3406 scores 6,350 in integer math, 2,694 in floating-point math, 26,178 in compression, 237 in cryptography, 163 in physics simulation, 839 in vector SIMD, 9 in the prime sieve and 3,409 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 89% below in integer math, 94% below in floating-point math, 89% below in compression, 98% below in cryptography, 85% below in physics simulation, 95% below in vector SIMD, 87% below in the prime sieve and 85% 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 Xeon L3406 has 2 physical cores and runs 4 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 2.27 GHz and boosts up to 2.53 GHz.

The Intel Xeon L3406 is a server processor and belongs to the Intel Xeon family. It launched in Mar 2010.

The Intel Xeon L3406 has 256 KB of L1 cache, 1 MB of L2 cache and 4 MB of L3 cache. That adds up to about 5.3 MB of cache, or 2.63 MB per core.

The Intel Xeon L3406 has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 4 MB. L3 is the largest level and makes up about 76% of the cache listed here.
