Intel® Pentium® G645T

The Intel Pentium G645T is a desktop processor with 2 cores and 2 threads, built on the Sandy Bridge architecture. It launched in Sep 2012. A 3-MB L3 cache backs the cores (1.8 MB per core). It supports DDR3 memory. It uses the FCLGA1155 socket. Rated TDP is 35 W.

The Intel Pentium G645T scores 1,142 in single-core performance and 1,258 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,199 for overall performance, 2,417 for productivity performance, 2,748 for creator performance, 1,172 for engineering performance and 3,741 for gaming performance. Its multi-core throughput works out to 629 per core, 629 per thread and 36 per watt. Its computed efficiency index is 203. Its performance index is 15, so its overall performance is 85% 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 Pentium G645T scores 5,020 in integer math, 2,652 in floating-point math, 23,641 in compression, 249 in cryptography, 163 in physics simulation, 854 in vector SIMD, 11 in the prime sieve and 3,220 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 91% below in integer math, 94% below in floating-point math, 90% below in compression, 98% below in cryptography, 85% below in physics simulation, 94% below in vector SIMD, 84% below in the prime sieve and 86% 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 Pentium G645T 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 2.50 GHz.

The Intel Pentium G645T is a desktop processor, belongs to the Intel Pentium family, uses the Sandy Bridge architecture and carries the codename Sandy Bridge. It launched in Sep 2012.

The Intel Pentium G645T 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 Pentium G645T 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.

The Intel Pentium G645T supports DDR3 memory and runs memory at up to 1,333 MT/s. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Pentium G645T includes integrated graphics (HD Graphics (6 EUs)) and clocks the graphics up to 1.10 GHz.

The Intel Pentium G645T uses the FCLGA1155 socket.

The Intel Pentium G645T has a rated TDP of 35 W.
