AMD® Ryzen™ 5 PRO 7645

The AMD Ryzen 5 PRO 7645 is a desktop processor with 6 cores and 12 threads, built on the Zen 4 architecture (5 nm process). It launched in Jun 2023. Clocks run from 3.8 GHz base to 5.1 GHz boost. A 32-MB L3 cache backs the cores (6.4 MB per core). The chip drops into the AM5 socket and exposes PCIe 5.0 (28 lanes). Rated TDP is 65 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 5 PRO 7645 scores 3,954 in single-core performance and 27,564 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 10,440 for overall performance, 23,452 for productivity performance, 22,277 for creator performance, 27,392 for engineering performance and 18,753 for gaming performance. Its multi-core throughput works out to 4,594 per core, 2,297 per thread and 424 per watt. Its computed efficiency index is 1,295. Its performance index is 129, so its overall performance is 29% above 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 AMD Ryzen 5 PRO 7645 scores 81,042 in integer math, 48,869 in floating-point math, 309,312 in compression, 18,036 in cryptography, 1,708 in physics simulation, 23,558 in vector SIMD, 214 in the prime sieve and 37,380 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 38% above in integer math, 6% above in floating-point math, 36% above in compression, 57% above in cryptography, 57% above in physics simulation, 52% above in vector SIMD, 219% above in the prime sieve and 65% above 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 AMD Ryzen 5 PRO 7645 has 6 physical cores and runs 12 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 3.80 GHz and boosts up to 5.10 GHz.

The AMD Ryzen 5 PRO 7645 is a desktop processor, belongs to the AMD Ryzen 5 family, uses the Zen 4 architecture, carries the codename Raphael and is manufactured on a 5 nm process. It launched in Jun 2023.

The AMD Ryzen 5 PRO 7645 has 384 KB of L1 cache, 6 MB of L2 cache and 32 MB of L3 cache. That adds up to about 38.4 MB of cache, or 6.40 MB per core. Each core has 1 MB of private L2 cache.

The AMD Ryzen 5 PRO 7645 has a 3-level cache hierarchy: L1 at 384 KB, L2 at 6 MB and L3 at 32 MB. L3 is the largest level and makes up about 83% of the cache listed here.
