AMD® Ryzen™ 3 3100U

The AMD Ryzen 3 3100U is a laptop processor with 2 cores and 2 threads, built on the Zen+ architecture. It launched in 2026. Clocks run from 1.9 GHz base to 3.2 GHz boost. A 4-MB L3 cache backs the cores (2.6 MB per core). The chip drops into the FP5 socket and exposes PCIe 3.0. Rated TDP is 15 W. Notable platform capabilities: AMD-V (Hardware Virtualization).

The AMD Ryzen 3 3100U scores 1,538 in single-core performance and 2,890 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,108 for overall performance, 4,032 for productivity performance, 4,358 for creator performance, 2,691 for engineering performance and 5,337 for gaming performance. Its multi-core throughput works out to 1,445 per core, 1,445 per thread and 193 per watt. Its computed efficiency index is 544. Its performance index is 26, so its overall performance is 74% 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 AMD Ryzen 3 3100U scores 7,686 in integer math, 5,046 in floating-point math, 31,879 in compression, 1,733 in cryptography, 209 in physics simulation, 1,764 in vector SIMD, 17 in the prime sieve and 4,044 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 87% below in integer math, 89% below in floating-point math, 86% below in compression, 85% below in cryptography, 81% below in physics simulation, 89% below in vector SIMD, 75% below in the prime sieve and 82% 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 AMD Ryzen 3 3100U has 2 physical cores and runs 2 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 1.90 GHz and boosts up to 3.20 GHz.

The AMD Ryzen 3 3100U is a laptop processor, belongs to the AMD Ryzen 3 family, uses the Zen+ architecture, carries the codename Picasso and is manufactured on a 12 nm process. It launched in 2026.

The AMD Ryzen 3 3100U has 192 KB of L1 cache, 1 MB of L2 cache and 4 MB of L3 cache. That adds up to about 5.2 MB of cache, or 2.60 MB per core. Each core has 512 KB of private L2 cache.

The AMD Ryzen 3 3100U has a 3-level cache hierarchy: L1 at 192 KB, L2 at 1 MB and L3 at 4 MB. L3 is the largest level and makes up about 77% of the cache listed here.
