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

Where Each One Wins

The recorded benchmark data shows a decisive split between these two processors. The AMD Ryzen Embedded 8640U has no benchmark entries in the database, meaning its performance profile is not yet characterized by recorded measurements. The Intel Core i5-14401E, by contrast, carries six Cinebench results spanning R15, R20, and R23 workloads.

Because the AMD part lacks recorded scores, the win count stands at zero for the Ryzen Embedded 8640U and zero for the Intel Core i5-14401E in direct head-to-head comparisons. The database does not yet contain paired measurements, so any direct comparison of the two parts must rely on architectural characteristics rather than empirical scores.

The Intel Core i5-14401E delivers multicore scores that place it in the 60th percentile against all CPUs in the database. Its average benchmark score of 5253 positions it close to several established desktop parts. The nearest rival, the Intel Xeon E5-2699A v4, scores 5259, a delta of -0.1 percent relative to the i5-14401E. The Intel Core i7-11700B scores 5241, a delta of 0.2 percent. The Intel Core i9-10850K also scores 5240, another 0.2 percent delta. The Intel Core i5-13400T scores 5210, a delta of 0.8 percent. These margins are all within one percentage point, indicating the i5-14401E sits in a tightly grouped performance band.

In single-core Cinebench R23, the i5-14401E records 2564 points. Its single-core R20 score is 1076, and its single-core R15 score is 258. Multicore results show a more substantial output: 18161 points in R23, 7627 in R20, and 1830 in R15. These numbers establish the Intel part as a capable performer in both single-threaded and multi-threaded workloads.

The AMD Ryzen Embedded 8640U, lacking any recorded benchmark scores, cannot be positioned relative to these figures. Its percentile rank of 50 against all CPUs suggests an average standing in the database, but this percentile is not supported by any actual benchmark entries. The data for the AMD part remains incomplete.

Architecture Differences

The two processors diverge sharply in their underlying designs. The AMD Ryzen Embedded 8640U uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. The Intel Core i5-14401E uses the Raptor Lake architecture under the Raptor Lake-R codename, built on a 10 nm process at Intel. This process gap is significant: the AMD part uses a smaller fabrication node, which typically enables higher transistor density and improved power efficiency.

Transistor counts reinforce this difference. The AMD chip integrates 25,000 million transistors on a die measuring 178 mm². The Intel part has no recorded transistor count in the database, but its die size is listed at 215 mm². The AMD die is smaller while carrying a known transistor population, indicating a denser implementation.

Cache hierarchies also differ. The AMD Ryzen Embedded 8640U provides 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel Core i5-14401E provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. The Intel part offers more cache at every level, which can benefit workloads with high data reuse.

Both processors feature six cores and twelve threads. Clock speeds differ: the AMD part has a base clock of 3.50 GHz and a boost clock of 4.90 GHz, while the Intel part runs at 2.50 GHz base and 4.70 GHz boost. The AMD chip holds the advantage in both base and boost frequencies.

Power characteristics diverge substantially. The AMD Ryzen Embedded 8640U carries a TDP of 28 watts and targets the mobile market segment. The Intel Core i5-14401E carries a TDP of 65 watts and targets the desktop segment. This reflects a fundamental design philosophy split: the AMD part prioritizes efficiency for embedded and mobile use, while the Intel part prioritizes sustained desktop performance.

Memory support differs as well. The AMD processor supports DDR5 exclusively through a dual-channel memory bus with a recorded bandwidth of 89.6 GB/s. The Intel processor supports both DDR4 and DDR5 through a dual-channel bus, but no bandwidth figure is recorded. Both parts support ECC memory.

PCIe capabilities diverge by generation and lane count. The AMD part uses Gen 4 with 20 lanes from the CPU. The Intel part uses Gen 5 with 16 lanes from the CPU. The Intel platform offers a newer PCIe generation, which can deliver higher per-lane bandwidth for compatible devices.

Integrated graphics differ. The AMD Ryzen Embedded 8640U includes a Radeon 760M. The Intel Core i5-14401E includes UHD Graphics 730. Neither part has recorded graphics benchmarks in the database.

Sockets and platforms are incompatible. The AMD chip uses AMD Socket FP8, while the Intel chip uses Intel Socket 1700. Neither processor has an unlocked multiplier. The AMD part launched on 2024-04-01, while the Intel part launched on 2024-06-30.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors. The wins counters for both sides sit at zero. The AMD Ryzen Embedded 8640U has no benchmark scores of any kind in its record. The Intel Core i5-14401E, however, has six recorded Cinebench results that establish its performance profile.

In Cinebench R23 multicore, the Intel Core i5-14401E scores 18161. This is its strongest recorded result and places it comfortably above the 60th percentile threshold for all CPUs. The single-core R23 score of 2564 shows a balanced ratio between single-threaded and multi-threaded output, approximately 7.1 to 1.

Cinebench R20 results follow the same pattern. The multicore score of 7627 and single-core score of 1076 produce a ratio of roughly 7.1 to 1. Cinebench R15 shows a multicore score of 1830 and a single-core score of 258, a ratio of approximately 7.1 to 1. The consistency across three Cinebench generations indicates that the Intel part scales predictably with thread count in this workload.

The average benchmark score for the Intel part is 5253. Its nearest rivals cluster tightly around this figure. The Intel Xeon E5-2699A v4 is nearly identical at 5259, just 0.1 percent lower. The Intel Core i7-11700B at 5241 is 0.2 percent higher than the i5-14401E, meaning the i5-14401E actually sits slightly above it. The Intel Core i9-10850K at 5240 is also 0.2 percent higher relative to the i5-14401E. The Intel Core i5-13400T at 5210 is 0.8 percent higher. These deltas indicate the i5-14401E performs within a narrow band of established desktop processors.

The AMD Ryzen Embedded 8640U has no comparable data. Its percentile rank of 50 against all CPUs exists without supporting benchmark entries, making direct numerical comparison impossible. Any assessment of its performance relative to the Intel part must rely on architectural parameters: higher clocks, smaller process node, lower TDP, and a different cache configuration.

The Intel part's 60th percentile standing against all CPUs, combined with its average score of 5253, gives it a clear recorded performance identity. The AMD part's 50th percentile rank, unsupported by any benchmark entries, leaves its performance identity undefined in the database. This asymmetry is the defining characteristic of the current comparison.
