AMD® Athlon™ Silver 7120U

The AMD Athlon Silver 7120U is a laptop processor with 2 cores and 2 threads, built on the Zen 2 architecture (6 nm process). It launched in Sep 2022. Clocks run from 2.4 GHz base to 3.5 GHz boost. A 2-MB L3 cache backs the cores (1.6 MB per core). It supports LPDDR5 memory. Rated TDP is 15 W.

The AMD Athlon Silver 7120U scores 1,862 in single-core performance and 3,022 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,372 for overall performance, 4,571 for productivity performance, 5,014 for creator performance, 2,814 for engineering performance and 6,342 for gaming performance. Its multi-core throughput works out to 1,511 per core, 1,511 per thread and 202 per watt. Its computed efficiency index is 613. Its performance index is 29, so its overall performance is 71% 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 Athlon Silver 7120U scores 8,183 in integer math, 4,968 in floating-point math, 36,708 in compression, 1,856 in cryptography, 181 in physics simulation, 2,363 in vector SIMD, 10 in the prime sieve and 4,149 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 86% below in integer math, 89% below in floating-point math, 84% below in compression, 84% below in cryptography, 83% below in physics simulation, 85% below in vector SIMD, 85% 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 Athlon Silver 7120U 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 2.40 GHz and boosts up to 3.50 GHz.

The AMD Athlon Silver 7120U is a laptop processor, belongs to the AMD Athlon family, uses the Zen 2 architecture and is manufactured on a 6 nm process. It launched in Sep 2022.

The AMD Athlon Silver 7120U has 128 KB of L1 cache, 1 MB of L2 cache and 2 MB of L3 cache. That adds up to about 3.1 MB of cache, or 1.56 MB per core. Each core has 512 KB of private L2 cache.

The AMD Athlon Silver 7120U has a 3-level cache hierarchy: L1 at 128 KB, L2 at 1 MB and L3 at 2 MB. L3 is the largest level and makes up about 64% of the cache listed here.

The AMD Athlon Silver 7120U supports LPDDR5 memory, uses 2 memory channels and runs memory at up to 5,500 MT/s. It does not support DDR5 and DDR4 memory.

The AMD Athlon Silver 7120U supports PCI Express 3.0 and provides up to 4 PCIe lanes.

The AMD Athlon Silver 7120U has a rated TDP of 15 W.
