Overview
SummaryThe AMD Ryzen 7 3800X is a desktop processor with 8 cores and 16 threads, built on the Zen 2 architecture (7 nm process). It launched in Jul 2019. Clocks run from 3.9 GHz base to 4.5 GHz boost. A 32-MB L3 cache backs the cores (4.6 MB per core). It supports DDR4 memory. The chip drops into the AM4 socket and exposes PCIe 4.0 (24 lanes). Rated TDP is 105 W.
Performance
12 metricsThe AMD Ryzen 7 3800X scores 2,709 in single-core performance and 22,955 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,886 for overall performance, 18,713 for productivity performance, 17,501 for creator performance, 23,529 for engineering performance and 13,866 for gaming performance. Its multi-core throughput works out to 2,869 per core, 1,435 per thread and 219 per watt. Its computed efficiency index is 770. Its performance index is 98, so its overall performance is 2% 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.
How these scores are computed
Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.
- Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
- Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
- Creator performance is 0.55 times multi-core plus 1.8 times single-core.
- Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
- Gaming performance is 3 times single-core plus 0.25 times multi-core.
- Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
- The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
- The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
Workload Benchmarks
8 workloadsScores 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 7 3800X scores 67,526 in integer math, 39,690 in floating-point math, 304,529 in compression, 19,291 in cryptography, 1,215 in physics simulation, 20,023 in vector SIMD, 100 in the prime sieve and 32,743 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 15% above in integer math, 14% below in floating-point math, 34% above in compression, 68% above in cryptography, 11% above in physics simulation, 29% above in vector SIMD, 49% above in the prime sieve and 45% 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.
