AMD® Ryzen™ 7 PRO 7840U

The AMD Ryzen 7 PRO 7840U is a laptop processor with 8 cores and 16 threads, built on the Zen 4 architecture (4 nm process). It launched in May 2023. Clocks run from 3.3 GHz base to 5.1 GHz boost. A 16-MB L3 cache backs the cores (3.1 MB per core). It supports DDR5, LPDDR5X memory. Rated TDP is 30 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 7 PRO 7840U scores 3,676 in single-core performance and 24,367 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 9,464 for overall performance, 20,985 for productivity performance, 20,019 for creator performance, 24,976 for engineering performance and 17,120 for gaming performance. Its multi-core throughput works out to 3,046 per core, 1,523 per thread and 812 per watt. Its computed efficiency index is 1,728. Its performance index is 117, so its overall performance is 17% 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 7 PRO 7840U scores 89,261 in integer math, 51,115 in floating-point math, 280,510 in compression, 17,163 in cryptography, 1,169 in physics simulation, 19,689 in vector SIMD, 78 in the prime sieve and 33,527 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 52% above in integer math, 11% above in floating-point math, 23% above in compression, 49% above in cryptography, 7% above in physics simulation, 27% above in vector SIMD, 16% above in the prime sieve and 48% 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 7 PRO 7840U has 8 physical cores and runs 16 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 and boosts up to 5.10 GHz.

The AMD Ryzen 7 PRO 7840U is a laptop processor, belongs to the AMD Ryzen 7 family, uses the Zen 4 architecture, carries the codename Phoenix and is manufactured on a 4 nm process. It launched in May 2023.

The AMD Ryzen 7 PRO 7840U has 512 KB of L1 cache, 8 MB of L2 cache and 16 MB of L3 cache. That adds up to about 24.5 MB of cache, or 3.06 MB per core. Each core has 1 MB of private L2 cache.

The AMD Ryzen 7 PRO 7840U has a 3-level cache hierarchy: L1 at 512 KB, L2 at 8 MB and L3 at 16 MB. L3 is the largest level and makes up about 65% of the cache listed here.
