AMD Ryzen 5 PRO 8640U vs Intel Core i5-14401E Comparison

Head-to-Head Benchmarks

The recorded data shows a consistent sweep in favor of the AMD Ryzen 5 PRO 8640U across all six head-to-head Cinebench comparisons. The AMD part wins every single test, with margins that hover near 10 percent in both single-core and multi-core workloads.

Starting with Cinebench R15, the AMD Ryzen 5 PRO 8640U scores 2014 in multi-core against 1830 for the Intel Core i5-14401E, a 10.1 percent advantage. Single-core R15 shows the same 10.1 percent gap, with AMD at 284 and Intel at 258. These are the largest relative deltas in the entire comparison, though the pattern holds firmly through every other test.

Moving to Cinebench R20, AMD again takes multi-core by 10 percent, scoring 8392 versus 7627. The single-core R20 result is also a 10 percent edge, 1184 against 1076. The consistency of the margin across both R15 and R20 suggests the performance gap is structural rather than workload-specific.

Cinebench R23 delivers the same story. AMD leads multi-core with 19982 against 18161, another 10 percent margin. Single-core R23 shows AMD at 2821 versus Intel at 2564, also 10 percent. No test in the head-to-head set produces an Intel win, and no test falls outside the 10 to 10.1 percent range.

The AMD processor's percentile ranking reinforces this dominance. It sits in the 81st percentile among all CPUs in the database, while the Intel part sits in the 60th percentile. The average benchmark score for AMD is 30254, compared to 5253 for Intel, though this average includes a broader set of tests than the Cinebench head-to-head set.

Looking at the nearest rival data for each processor provides additional context. The AMD Ryzen 5 PRO 8640U lands within 0.6 percent of processors like the Intel Core i9-11980HK, AMD Ryzen 5 7640HS, and AMD Ryzen 7 7736U, all of which have average scores around 30200 to 30400. The Intel Core i5-14401E, by contrast, sits near the AMD Ryzen 7 2700X in the database, but its nearest rivals include the Intel Core i9-10850K and Intel Core i5-13400T, all clustered around 5210 to 5259. The Intel part's average score is roughly 17 percent lower than the AMD part's average, even before considering the head-to-head results.

The Verdict

The data points decisively toward the AMD Ryzen 5 PRO 8640U for any workload that relies on Cinebench-style rendering or CPU compute. It wins all six head-to-head tests, with a uniform 10 percent advantage. The AMD part also carries a higher database percentile (81 versus 60) and a substantially higher average benchmark score (30254 versus 5253).

That said, the two processors serve different market segments, and the Intel Core i5-14401E is not without its own positioning. The Intel part is a desktop processor on Socket 1700 with a 65 W TDP, while the AMD part is a mobile processor on Socket FP7 with a 28 W TDP. For a desktop build where power draw is less constrained, the Intel part may still be a reasonable choice, especially given its support for both DDR4 and DDR5 memory and its PCIe Gen 5 interface. But strictly from compute performance as recorded in the database, the AMD part delivers a clear and consistent lead.

Users who prioritize raw multi-threaded throughput or single-thread responsiveness in Cinebench should select the AMD Ryzen 5 PRO 8640U. Users who require a desktop socket, PCIe Gen 5 connectivity, or the flexibility of DDR4 memory support may prefer the Intel Core i5-14401E, though they will accept a 10 percent performance deficit in every recorded Cinebench test.

Architecture Differences

The two processors come from fundamentally different design lineages. The AMD Ryzen 5 PRO 8640U uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. It packs 25,000 million transistors into a 178 mm² die. The Intel Core i5-14401E uses the Raptor Lake architecture under the Raptor Lake-R codename, built on a 10 nm process at Intel, with a 215 mm² die size and no transistor count recorded in the database.

Both processors have 6 cores and 12 threads, so the core count is identical. The cache layouts differ meaningfully. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. Intel's larger per-core L1 and L2 caches and larger L3 do not translate into a performance win in the recorded Cinebench tests, which suggests the AMD architecture's efficiency advantage on the 4 nm node offsets the cache deficit.

Clock speeds also differ. AMD has a 3.50 GHz base clock and a 4.90 GHz boost clock. Intel has a 2.50 GHz base clock and a 4.70 GHz boost clock. AMD's higher boost clock likely contributes to its single-core Cinebench wins, while its higher base clock and 4 nm process help sustain multi-core throughput.

Memory support separates the two. AMD supports DDR5 in a dual-channel configuration with a recorded memory bandwidth of 89.6 GB/s. Intel supports both DDR4 and DDR5 in dual-channel, but the database does not record a memory bandwidth figure for Intel. Both processors support ECC memory.

PCIe connectivity differs significantly. AMD provides PCIe Gen 4 with 20 lanes (CPU only). Intel provides PCIe Gen 5 with 16 lanes (CPU only). This gives Intel a bandwidth advantage for storage or GPU connectivity, though it does not appear in the Cinebench results.

Integrated graphics also differ. AMD uses the Radeon 760M, while Intel uses the UHD Graphics 730. The database does not record graphics benchmarks for either part, so any comparison there would be speculative.

Where Each One Wins

The AMD Ryzen 5 PRO 8640U wins every recorded head-to-head benchmark. It leads Cinebench R15 multi-core by 10.1 percent, R15 single-core by 10.1 percent, R20 multi-core by 10 percent, R20 single-core by 10 percent, R23 multi-core by 10 percent, and R23 single-core by 10 percent. The database also shows AMD holding the 81st percentile among all CPUs, compared to Intel's 60th percentile.

The AMD part's wins extend to its average benchmark score, which includes additional tests beyond Cinebench. The database records AMD scores for data compression (260925), data encryption (15843), extended instructions (19130), prime number finding (78), floating point math (45265), integer math (74875), multithread (22795), physics (1154), random string sorting (32114), and single-thread (3732). These scores contribute to the 30254 average, far above Intel's 5253.

The Intel Core i5-14401E does not win a single head-to-head test. Its advantages appear in the specification sheet rather than the benchmark results. Intel offers PCIe Gen 5 with 16 lanes, while AMD offers PCIe Gen 4 with 20 lanes. Intel supports both DDR4 and DDR5 memory, while AMD only supports DDR5. Intel also has a larger L3 cache (20 MB versus 16 MB) and larger per-core L1 and L2 caches. These features may matter for specific desktop use cases, but they do not translate into Cinebench performance wins.

For workloads that resemble Cinebench rendering or general CPU compute, the AMD part is the clear winner. For workloads that depend on PCIe Gen 5 bandwidth or DDR4 memory compatibility, the Intel part offers features that AMD does not.
