AMD Ryzen Embedded 8640U vs Intel Core i5-14401TE Comparison

Head-to-Head Benchmarks

The recorded database contains no direct benchmark scores for either the AMD Ryzen Embedded 8640U or the Intel Core i5-14401TE. Both processors return an average benchmark score of 0, and the head-to-head comparison table is empty. Consequently, there are no exact numerical deltas to cite for multi-threaded workloads, single-threaded tasks, or any synthetic test suite.

What the data does show is that both CPUs occupy the 50th percentile in the database's ranking of all processors. This indicates that neither chip has a recorded performance profile that pushes it above or below the median position. The absence of benchmark entries does not mean the parts are equivalent in real-world capability. It simply means the database has not yet captured measurable results for either unit.

Without benchmark scores, the only quantitative comparisons available come from the specification fields. The AMD part boosts to 4.90 GHz, while the Intel part boosts to 4.50 GHz. That is a 0.40 GHz advantage for AMD in maximum clock speed. The AMD base clock sits at 3.50 GHz, versus 2.00 GHz for Intel, a 1.50 GHz difference in favor of AMD for sustained all-core operation at stock settings.

The Intel chip counters with a larger L3 cache. It has 20 MB shared, while AMD has 16 MB shared, a 4 MB difference. Intel also has a larger L2 allocation per core: 1.25 MB versus 1 MB per core for AMD. Across six cores, that works out to 7.5 MB of total L2 for Intel, versus 6 MB for AMD, though the per-core figures are what the database records.

Memory bandwidth numbers are only present for AMD: 89.6 GB/s with dual-channel DDR5. Intel has no recorded memory bandwidth figure in the database, so no comparison is possible on that metric. Both parts support ECC memory, which is notable for embedded and small-server use cases.

Where Each One Wins

The AMD Ryzen Embedded 8640U wins on clock speed. Its 4.90 GHz boost clock is 0.40 GHz higher than Intel's 4.50 GHz, and its 3.50 GHz base clock is 1.50 GHz higher than Intel's 2.00 GHz base. For workloads that are latency-sensitive or lightly threaded, the higher clocks suggest an advantage in raw single-thread responsiveness, assuming the architecture delivers comparable instructions per clock. The 4 nm TSMC process node also gives AMD a manufacturing advantage in density and power characteristics, though the database does not record thermal or efficiency test results.

The Intel Core i5-14401TE wins on cache capacity and PCIe generation. The 20 MB L3 cache is 4 MB larger than AMD's 16 MB, and the per-core L2 is 1.25 MB versus 1 MB, a 25% larger L2 per core. For workloads that repeatedly access a working set larger than 16 MB, the extra L3 can reduce memory traffic. Intel also supports PCIe Gen 5 with 16 lanes on the CPU, while AMD uses PCIe Gen 4 with 20 lanes. Gen 5 doubles the per-lane bandwidth versus Gen 4, so a device using fewer than 16 lanes could see higher throughput on Intel, though the database does not list real-world PCIe throughput figures.

Intel also supports both DDR4 and DDR5 memory, while AMD only lists DDR5. That gives Intel flexibility for systems with existing DDR4 inventory, which can matter for embedded deployments with long lifecycles. AMD's memory bandwidth figure of 89.6 GB/s is recorded, but Intel's is absent, so a direct bandwidth comparison is impossible.

The Verdict

The data supports a split decision based on workload priorities. For applications that depend on high clock speeds, especially base clock sustained operation, the AMD Ryzen Embedded 8640U is the stronger choice on paper. Its 3.50 GHz base clock is 1.50 GHz higher than Intel's 2.00 GHz base, which suggests better performance in scenarios where the CPU runs at stock settings for extended periods without boosting. The 4.90 GHz boost clock also leads Intel by 0.40 GHz.

For applications that benefit from larger on-die caches, the Intel Core i5-14401TE is the better pick. The 20 MB L3 cache and 1.25 MB per-core L2 give it a clear capacity advantage. The PCIe Gen 5 support with 16 lanes also favors Intel for systems with high-throughput expansion cards.

Neither part has recorded benchmark results, so the verdict rests entirely on specification analysis. Both sit at the 50th percentile, which means the database treats them as statistically average pending actual measurements. A builder choosing between them should prioritize clock speed versus cache size, and memory flexibility (DDR4 plus DDR5 on Intel, DDR5 only on AMD) versus process node (4 nm TSMC on AMD, 10 nm Intel on the Intel part).
