AMD Ryzen 5 8400F vs Qualcomm Snapdragon X1P-64-100 Comparison

AMD Ryzen 5 8400F is a desktop processor built for the AM5 platform, while Qualcomm Snapdragon X1P-64-100 targets mobile devices. The benchmark database shows a significant gap in measured performance, but the two parts serve different physical and thermal environments. The Ryzen 5 8400F has a full set of benchmark results, while the Snapdragon X1P-64-100 has no recorded benchmark scores in the database. This makes direct numerical comparison impossible, but the architectural and specification differences are clear.

Where Each One Wins

The AMD Ryzen 5 8400F wins in every measurable category because it is the only one of the two with benchmark data. Its average benchmark score is 25005, placing it in the 77th percentile of all CPUs. The Snapdragon X1P-64-100 has an average benchmark score of 0 and sits in the 50th percentile, meaning the database contains no performance results for it. The Ryzen 5 8400F delivers strong multi-threaded performance, with a Cinebench R23 multi-core score of 20851 and a single-core score of 2943. Its 3DMark 16-thread score is 6091, and its max-thread score reaches 6165. PassMark multi-thread testing shows 24389, while integer math scores 74021 and floating-point math scores 46217.

The Snapdragon X1P-64-100 has no wins because no test results exist. Its advantage lies in its mobile design: a 35 W TDP and integrated Adreno X1-85 graphics. The Ryzen 5 8400F has no integrated graphics and a 65 W TDP. For a desktop builder, the Ryzen 5 8400F is the only part with verified performance. For a mobile system designer, the Snapdragon X1P-64-100 offers a lower power envelope and built-in graphics, but the database provides no evidence of its computational speed.

Architecture Differences

The Ryzen 5 8400F uses the Zen 4 architecture with the Phoenix codename, built on a 4 nm TSMC process. It has 6 cores and 12 threads, with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. The chip contains 25,000 million transistors on a 178 mm² die. Cache is organized as 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Memory support is DDR5 on a dual-channel bus with 83.2 GB/s bandwidth. The CPU provides 20 PCIe Gen 4 lanes and fits AMD Socket AM5. The multiplier is unlocked, and the part number is 100-000001591.

The Snapdragon X1P-64-100 uses the Oryon codename from the Snapdragon X Plus generation, also on a 4 nm TSMC process. It has 10 cores and 10 threads, meaning no simultaneous multithreading. The base clock is 3.40 GHz with no boost clock listed. Cache differs substantially: 288 KB L1 per core, 12 MB L2 per module, and 6 MB shared L3. Memory support is LPDDR5X on a dual-channel bus with 135.2 GB/s bandwidth, which is 52 GB/s higher than the AMD part. The Qualcomm chip provides 12 PCIe Gen 4 lanes and uses the BGA 2073 socket. It includes an Adreno X1-85 integrated GPU, has a locked multiplier, and carries the part number X1P64100. The Snapdragon has no listed transistor count or die size.

The Verdict

The data supports the AMD Ryzen 5 8400F for any application requiring measured compute performance. It has a complete benchmark profile, a 77th percentile ranking, and an average score of 25005. The Snapdragon X1P-64-100 has no benchmark results, so no performance claim can be made from the database. The Ryzen 5 8400F is the correct choice for desktop workloads where the 65 W TDP and AM5 socket are acceptable. The Snapdragon X1P-64-100 is the correct choice for a mobile design that needs a 35 W TDP and integrated graphics, but its computational capability is unknown from recorded data. The Ryzen 5 8400F also offers an unlocked multiplier for overclocking, while the Snapdragon does not.

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database for these two processors. The Ryzen 5 8400F has 23 recorded benchmark scores, while the Snapdragon X1P-64-100 has zero. Direct comparison of specific test scores is therefore not possible. The Ryzen 5 8400F shows strong results in its own right: Cinebench R23 multi-core reaches 20851, R20 multi-core hits 8757, and R15 multi-core records 2101. Single-core results are 2943 in R23, 1236 in R20, and 296 in R15. PassMark tests show 24389 in multi-thread, 3685 in single-thread, 288158 in data compression, 16646 in data encryption, and 22175 in extended instructions. The Snapdragon X1P-64-100 has no comparable numbers, so the database cannot confirm any performance relationship between the two.

The largest wins for the Ryzen 5 8400F are in multi-threaded workloads, where its 12 threads provide a clear advantage over the Snapdragon's 10 threads with no SMT. The 3DMark 16-thread score of 6091 and max-thread score of 6165 indicate consistent scaling across thread counts. The PassMark integer math score of 74021 and floating-point score of 46217 further demonstrate computational throughput. The Snapdragon X1P-64-100 offers higher memory bandwidth (135.2 GB/s vs. 83.2 GB/s) and more PCIe lanes are not present (12 vs. 20), so the AMD part has more PCIe connectivity. The Snapdragon also has a lower TDP and integrated graphics, but these are not benchmark scores.

Specification Differences

The two processors diverge in nearly every specification field. The Ryzen 5 8400F has 6 cores and 12 threads, while the Snapdragon X1P-64-100 has 10 cores and 10 threads.

Architecture names are Zen 4 (Phoenix) for AMD and Oryon for Qualcomm, with the Snapdragon generation listed as Snapdragon X (Plus). Both use 4 nm TSMC process nodes. Transistor count and die size are listed only for AMD: 25,000 million transistors and 178 mm².

Cache configurations are markedly different. AMD uses 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Qualcomm uses 288 KB L1 per core, 12 MB L2 per module, and 6 MB shared L3. Memory support is DDR5 for AMD and LPDDR5X for Qualcomm, both dual-channel, with bandwidth of 83.2 GB/s versus 135.2 GB/s. PCIe is Gen 4 with 20 lanes for AMD and Gen 4 with 12 lanes for Qualcomm.
