AMD Ryzen 5 PRO 8640HS vs Intel Core i5-14500T Comparison

Where Each One Wins

The benchmark data splits this comparison into two distinct profiles. The AMD Ryzen 5 PRO 8640HS takes 5 of the 17 recorded tests, while the Intel Core i5-14500T wins 12. That headline count, however, does not tell the whole story. The AMD part concentrates its wins in specific categories: Cinebench R23 multi-core, Cinebench R23 single-core, Cinebench R15 single-core, Passmark extended instructions, and Passmark random string sorting. These are workloads that reward higher boost clocks and efficient instruction processing. The Intel part, by contrast, dominates the older Cinebench releases (R15 and R20), along with most Passmark math and encryption workloads.

The use-case split is sharp. For users running modern rendering engines that scale with sustained multi-core throughput, the AMD Ryzen 5 PRO 8640HS delivers a decisive edge, especially in Cinebench R23 where it leads by 53.6%. For compression, encryption, physics simulation, and integer-heavy floating point math, the Intel Core i5-14500T is the stronger pick. The Intel part also wins Passmark single-thread by 4.7%, which matters for lightly threaded applications. The AMD part counters with a 39% lead in Cinebench R23 single-core, a much larger margin in that specific test.

The data suggests a generational split in workload behavior. The AMD processor, with its Zen 4 architecture on a 4 nm process, shows particular strength in newer Cinebench versions and extended instruction workloads. The Intel processor, built on Raptor Lake Refresh with a 10 nm process, maintains advantages in legacy Cinebench versions and classic Passmark math tests. Buyers should match the processor to the software they actually run, because the winner changes depending on the benchmark generation.

Architecture Differences

The two processors diverge fundamentally in design philosophy. The AMD Ryzen 5 PRO 8640HS uses a monolithic 6-core, 12-thread configuration based on Zen 4 architecture, codenamed Hawk Point, built on a 4 nm process at TSMC. The Intel Core i5-14500T uses a hybrid 14-core, 20-thread layout under the Raptor Lake Refresh codename, fabricated on Intel's 10 nm process. The AMD die measures 178 mm² with 25,000 million transistors. The Intel die is larger at 215 mm², but the database records no transistor count for it.

Cache hierarchies differ substantially. The AMD part allocates 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The Intel part provides 80 KB L1 per core, 1.25 MB L2 per core, and 24 MB shared L3. That larger L3 cache on the Intel side helps in data-heavy workloads, which shows up in the compression and encryption benchmarks. The AMD part counters with higher clock speeds: a 3.50 GHz base and 4.90 GHz boost versus the Intel's 1.70 GHz base and 4.80 GHz boost. The AMD base clock is more than double the Intel base clock, a reflection of the mobile-oriented design versus the desktop power envelope.

Memory support also diverges. The AMD part supports DDR5 only, dual-channel, with a recorded memory bandwidth of 89.6 GB/s. The Intel part supports both DDR4 and DDR5, dual-channel, with no memory bandwidth figure recorded in the database. Both support ECC memory. PCIe connectivity differs as well: the AMD processor offers Gen 4 with 20 lanes (CPU only), while the Intel processor offers Gen 5 with 16 lanes (CPU only). Integrated graphics are present on both: Radeon 760M on the AMD side, UHD Graphics 770 on the Intel side.

Market positioning and physical requirements are equally distinct. The AMD Ryzen 5 PRO 8640HS is a mobile processor on AMD Socket FP7 with a 28 W TDP. The Intel Core i5-14500T is a desktop processor on Intel Socket 1700 with a 35 W TDP. The AMD part released on 2024-04-15, while the Intel part released earlier on 2024-01-07. Neither has an unlocked multiplier, so overclocking is not a differentiator.

Head-to-Head Benchmarks

The largest single win belongs to the AMD Ryzen 5 PRO 8640HS in Cinebench R23 multi-core. The AMD part scores 18104 against 11790 for the Intel part, a 53.6% advantage. This is the defining result of the comparison. In Cinebench R23 single-core, the AMD part again leads by 39%, scoring 2555 versus 1838. These two results anchor the AMD case for modern rendering performance.

The Intel Core i5-14500T wins the older Cinebench releases. In Cinebench R15 multi-core, Intel scores 2022 against 1824, a 9.8% lead. In Cinebench R20 multi-core, Intel scores 8177 against 7603, a 7% lead. In Cinebench R20 single-core, Intel scores 1154 against 1073, also a 7% lead. Only in Cinebench R15 single-core does the AMD part win, scoring 257 against 252, a narrow 2% margin.

Passmark results favor Intel in most categories. Floating point math shows Intel at 58869 versus 43019, a 26.9% advantage. Integer math shows Intel at 80922 versus 69839, a 13.7% lead. Physics simulation goes to Intel at 1288 versus 1043, a 19% margin. Data compression favors Intel at 262417 versus 246446, a 6.1% lead. Data encryption is close, with Intel at 15410 versus 14962, a 2.9% edge. Find prime numbers goes to Intel at 81 versus 71, a 12.3% difference. Passmark multi-thread goes to Intel at 22910 versus 21465, a 6.3% lead. Passmark single-thread goes to Intel at 3736 versus 3561, a 4.7% margin.

The AMD part claims two notable Passmark wins. Extended instructions scores 18507 versus 16043, a 15.4% advantage. Random string sorting scores 30235 versus 28462, a 6.2% edge. These wins, combined with the Cinebench R23 results, show the AMD processor excels in specific instruction-heavy and sorting workloads.

The Verdict

The data defines two clear buyer profiles. Choose the AMD Ryzen 5 PRO 8640HS if the workload centers on modern Cinebench R23 rendering, extended instruction sets, or random string sorting. The 53.6% multi-core lead and 39% single-core lead in Cinebench R23 are decisive for those applications. The mobile form factor, 28 W TDP, and 4 nm process also make it the appropriate pick for portable systems where power efficiency matters.

Choose the Intel Core i5-14500T if the workload relies on legacy Cinebench R15 or R20, floating point math, integer math, physics simulation, data compression, or encryption. The 26.9% floating point advantage and 19% physics lead are substantial. The 14-core, 20-thread configuration provides more parallelism for traditional multi-threaded Passmark workloads, and the desktop Socket 1700 platform suits stationary builds. The Intel part also records a 4.7% single-thread Passmark win, which matters for everyday responsiveness in lightly threaded software.

Both processors sit at the 80th percentile against all CPUs in the database. The AMD part averages 28478 across all benchmark scores, while the Intel part averages 28065. The AMD part's nearest rivals include the Intel Xeon E-2436 at a 0.2% lower average, the AMD Ryzen 7 PRO 6850HS at 0.2% lower, and the Intel Core 5 220H at 0.3% lower. The Intel part's nearest rivals include the AMD Ryzen 5 PRO 8500GE at parity, the AMD Ryzen 5 PRO 5655G at 0.1% higher, and the Intel Core i9-12900H at 0.2% higher. The overall averages are close, but the workload-specific results diverge sharply. There is no universal winner, only the right tool for the specific task.
