Intel® Core™ i3-2125

The Intel Core i3-2125 is a desktop processor with 2 cores and 4 threads, built on the Sandy Bridge architecture (32 nm process). It launched in Sep 2011. A 3-MB L3 cache backs the cores (1.8 MB per core). The chip drops into the FCLGA1155 socket and exposes PCIe 2.0 (16 lanes). Rated TDP is 65 W.

The Intel Core i3-2125 scores 1,495 in single-core performance and 1,994 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,727 for overall performance, 3,389 for productivity performance, 3,788 for creator performance, 1,857 for engineering performance and 4,984 for gaming performance. Its multi-core throughput works out to 997 per core, 499 per thread and 31 per watt. Its computed efficiency index is 214. Its performance index is 21, so its overall performance is 79% 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 Core i3-2125 scores 9,560 in integer math, 3,562 in floating-point math, 41,561 in compression, 337 in cryptography, 263 in physics simulation, 1,849 in vector SIMD, 13 in the prime sieve and 6,041 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 84% below in integer math, 92% below in floating-point math, 82% below in compression, 97% below in cryptography, 76% below in physics simulation, 88% below in vector SIMD, 81% below in the prime sieve and 73% 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 Core i3-2125 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 3.30 GHz.

The Intel Core i3-2125 is a desktop processor, belongs to the Intel Core i3 family, uses the Sandy Bridge architecture, carries the codename Sandy Bridge and is manufactured on a 32 nm process. It launched in Sep 2011.

The Intel Core i3-2125 has 128 KB of L1 cache, 512 KB of L2 cache and 3 MB of L3 cache. That adds up to about 3.6 MB of cache, or 1.81 MB per core. Each core has 256 KB of private L2 cache.

The Intel Core i3-2125 has a 3-level cache hierarchy: L1 at 128 KB, L2 at 512 KB and L3 at 3 MB. L3 is the largest level and makes up about 83% of the cache listed here.
