Intel® Pentium® 1403

The Intel Pentium 1403 is a server processor with 2 cores and 2 threads, built on the Sandy Bridge architecture. It launched in May 2012. A 5-MB L3 cache backs the cores (3.8 MB per core). It supports DDR3 memory. It uses the FCLGA1356 socket. Rated TDP is 80 W.

The Intel Pentium 1403 scores 990 in single-core performance and 1,851 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,354 for overall performance, 2,589 for productivity performance, 2,800 for creator performance, 1,724 for engineering performance and 3,433 for gaming performance. Its multi-core throughput works out to 926 per core, 926 per thread and 23 per watt. Its computed efficiency index is 151. Its performance index is 17, so its overall performance is 83% 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 Pentium 1403.

The Intel Pentium 1403 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 2.60 GHz.

The Intel Pentium 1403 is a server processor, belongs to the Intel Pentium family, uses the Sandy Bridge architecture and carries the codename Sandy Bridge. It launched in May 2012.

The Intel Pentium 1403 has 512 KB of L1 cache, 2 MB of L2 cache and 5 MB of L3 cache. That adds up to about 7.5 MB of cache, or 3.75 MB per core.

The Intel Pentium 1403 has a 3-level cache hierarchy: L1 at 512 KB, L2 at 2 MB and L3 at 5 MB. L3 is the largest level and makes up about 67% of the cache listed here.

The Intel Pentium 1403 supports DDR3 memory and runs memory at up to 1,066 MT/s. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Pentium 1403 uses the FCLGA1356 socket.

The Intel Pentium 1403 has a rated TDP of 80 W.
