AMD Ryzen 5 PRO 8640HS vs Intel Core i5-14501E Comparison

Head-to-Head Benchmarks

The recorded data for this comparison is one-sided. The AMD Ryzen 5 PRO 8640HS has a complete set of benchmark results across multiple test suites, while the Intel Core i5-14501E has no recorded benchmark scores in the database. This means the head-to-head comparison relies entirely on the AMD processor's measured performance and its position relative to other CPUs in the database.

The Ryzen 5 PRO 8640HS achieves an average benchmark score of 28478, placing it in the 80th percentile of all CPUs tracked in the database. Its nearest rivals include the Intel Xeon E-2436 with an average score of 28530 (0.2% higher), the AMD Ryzen 7 PRO 6850HS with 28549 (0.2% higher), the Intel Core 5 220H with 28574 (0.3% higher), and the AMD Ryzen 7 PRO 6850U with 28379 (0.3% lower). This places the Ryzen 5 PRO 8640HS in a tightly packed performance cluster where the differences among nearby processors are within a fraction of a percent.

In Cinebench R23 multi-core, the Ryzen 5 PRO 8640HS scores 18104 points, while its single-core score reaches 2555 points. The Cinebench R20 results show 7603 points multi-core and 1073 points single-core, and the older Cinebench R15 test yields 1824 points multi-core and 257 points single-core. These scores indicate that the processor delivers balanced performance across both heavily threaded workloads and single-threaded tasks, with the multi-core advantage scaling consistently across all three Cinebench versions.

PassMark results further characterize the processor's strengths. The multi-thread score is 21465, while single-thread performance registers 3561. Integer math workloads produce 69839 points, floating-point math reaches 43019 points, and extended instruction sets score 18507. Data compression scores 246446, data encryption scores 14962, random string sorting scores 30235, and the find prime numbers test returns 71. Physics testing produces 1043 points.

The Intel Core i5-14501E has no benchmark entries in the database, so direct score comparisons are impossible. The database shows a 50th percentile ranking for the Intel processor, but with an average benchmark score of zero and no rival data, this percentile reflects the absence of recorded measurements rather than an evaluated performance level. The AMD processor's 80th percentile ranking is backed by actual test results, whereas the Intel processor's ranking lacks supporting data.

Architecture Differences

The two processors come from different design generations and manufacturing processes. The AMD Ryzen 5 PRO 8640HS uses the Zen 4 architecture under the Hawk Point codename, part of the Ryzen 5 generation line. It is built on a 4 nm process at TSMC with 25,000 million transistors on a 178 mm² die. The Intel Core i5-14501E uses the Raptor Lake architecture under the Raptor Lake-R codename, part of the Core 14th Gen series. It is built on a 10 nm process at Intel with a 215 mm² die size, though transistor count is not recorded.

Cache configurations differ substantially. The AMD processor provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel processor provides 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and a larger 24 MB of shared L3 cache. This gives the Intel chip more total cache capacity, particularly in the L3 tier where it offers 8 MB more shared memory.

Clock speeds and power characteristics also diverge. The AMD processor has a base clock of 3.50 GHz and a boost clock of 4.90 GHz, with a TDP of 28 watts. The Intel processor has a base clock of 3.30 GHz and a higher boost clock of 5.20 GHz, but a TDP of 65 watts. The Intel part boosts 300 MHz higher while consuming more than double the thermal design power.

Memory support differs as well. The AMD processor supports DDR5 memory exclusively with dual-channel configuration and a recorded memory bandwidth of 89.6 GB/s. The Intel processor supports both DDR4 and DDR5 memory with dual-channel configuration, though its memory bandwidth is not recorded in the database. Both processors support ECC memory.

Platform and connectivity specifications show distinct approaches. The AMD processor uses AMD Socket FP7, targets the mobile market segment, and provides PCIe Gen 4 with 20 lanes from the CPU. The Intel processor uses Intel Socket 1700, targets the desktop market segment, and provides PCIe Gen 5 with 16 lanes from the CPU. The AMD chip integrates Radeon 760M graphics, while the Intel chip integrates UHD Graphics 770.

Release timing places the AMD processor first, with a release date of April 15, 2024. The Intel processor followed with a release date of June 30, 2024. Both processors remain in active production, and neither has an unlocked multiplier.

Where Each One Wins

Based on the recorded data, the AMD Ryzen 5 PRO 8640HS holds the advantage in every measured category because it has benchmark results and the Intel Core i5-14501E has none. The AMD processor's strong multi-threaded showing in Cinebench R23 with 18104 points, Cinebench R20 with 7603 points, and Cinebench R15 with 1824 points positions it well for productivity workloads that scale across cores.

Single-threaded performance from the AMD processor, demonstrated by 2555 points in Cinebench R23 single-core and 3561 in PassMark single-thread, supports responsiveness in applications that rely on one core. The PassMark integer math score of 69839 and floating-point math score of 43019 indicate solid general-purpose computational capability.

The Intel Core i5-14501E cannot claim any benchmark wins because the database contains no measured scores for it. Its higher boost clock of 5.20 GHz compared to the AMD's 4.90 GHz suggests potential for single-thread performance, but without recorded results this remains unverified. Similarly, its larger 24 MB L3 cache compared to the AMD's 16 MB could benefit cache-sensitive workloads, but no data confirms this advantage.

The AMD processor's 28 watt TDP makes it suited for power-constrained environments, whereas the Intel processor's 65 watt TDP targets a desktop platform where power draw is less restrictive. The AMD processor's mobile market segment and FP7 socket indicate integration into laptops and compact systems. The Intel processor's desktop market segment and Socket 1700 indicate traditional tower and workstation builds.

The Verdict

The database presents a clear picture: the AMD Ryzen 5 PRO 8640HS delivers measured performance across every benchmark in its test suite, while the Intel Core i5-14501E has no recorded results. Users seeking a processor with verified performance data should choose the AMD part. Its 80th percentile ranking among all CPUs, backed by an average benchmark score of 28478, places it among capable performers in the database.

The Intel processor's 50th percentile ranking with zero benchmark scores does not reflect actual performance. It simply indicates the absence of data. The Intel part offers a higher boost clock and larger L3 cache on paper, and it supports both DDR4 and DDR5 memory, but the database cannot confirm how these specifications translate into real-world results.

For workloads that demand verified multi-threaded throughput, the AMD processor's Cinebench R23 multi-core score of 18104 and PassMark multi-thread score of 21465 provide concrete reference points. For single-threaded tasks, the Cinebench R23 single-core score of 2555 and PassMark single-thread score of 3561 offer similar assurance. The AMD processor also delivers these results at a 28 watt TDP, which suits mobile and low-power desktop configurations.

The Intel processor may appeal to users building on Socket 1700 platforms or requiring PCIe Gen 5 connectivity, which the AMD processor does not offer. The Intel part provides 16 lanes of PCIe Gen 5 compared to the AMD's 20 lanes of PCIe Gen 4. It also supports DDR4 memory, which could matter for users migrating from older platforms. However, these are platform considerations rather than performance verifications.
