Architecture Differences

The AMD Ryzen 5 PRO 8645HS is built on Zen 4 architecture with the Hawk Point codename, belonging to the 8000 series and Ryzen 5 generation. It uses a 4 nm process node fabricated by TSMC, with 25,000 million transistors on a 178 mm² die. The Intel Core i5-14490F is based on Raptor Lake architecture with the Raptor Lake-R codename, part of the Core 14th Gen and Core i5 generation. It uses a 10 nm process node from Intel on a 215 mm² die size.

Cache configurations differ substantially. The AMD chip provides 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The Intel chip offers 80 KB L1 per core, 1.25 MB L2 per core, and 24 MB shared L3. This gives Intel a clear capacity advantage at every cache level, particularly in L3 where it holds 50% more shared cache.

Memory support separates the two as well. The AMD Ryzen 5 PRO 8645HS supports only DDR5 memory in dual-channel configuration, with a memory bandwidth of 89.6 GB/s and ECC memory support. The Intel Core i5-14490F supports both DDR4 and DDR5 in dual-channel, but memory bandwidth is not recorded, and it does not support ECC memory. This makes the AMD part suited for error-corrected workloads, while Intel offers broader memory compatibility.

The market segments differ: the AMD processor is a mobile part on AMD Socket FP7, while the Intel processor is a desktop part on Intel Socket 1700. Both are currently active in production and neither has an unlocked multiplier. The AMD chip has two part numbers (100-000001315 for FP7r2 and 100-000001388 for FP7), while Intel has one part number (SRN35). The AMD release date is 2024-04-15, while Intel's is 2023-12-31.

The Verdict

The benchmark data consistently favors the Intel Core i5-14490F across all 17 head-to-head tests. The Intel chip wins every single comparison, with margins ranging from a narrow 0.4% to a dominant 42.3%. Its average benchmark score of 38149 places it at the 86th percentile of all CPUs, while the AMD Ryzen 5 PRO 8645HS sits at the 82nd percentile with an average score of 30879.

For users prioritizing multi-threaded performance, the Intel chip is the clear choice. Its 10 cores and 16 threads, combined with larger cache, deliver decisive wins in Cinebench multicore tests and PassMark multithread workloads. The Intel part also holds a substantial edge in single-threaded performance, as shown in Cinebench R23 single-core where it scores 3247 versus 2787 for AMD, a 14.2% advantage.

The AMD Ryzen 5 PRO 8645HS does have specific advantages in its feature set. Its integrated Radeon 760M graphics make it suitable for systems without a discrete GPU. ECC memory support and a more advanced 4 nm process node are also differentiators. For mobile applications requiring low power, the 45 W TDP is notably lower than Intel's 65 W TDP, although the Intel chip's base clock is significantly lower at 2.50 GHz versus 4.30 GHz for AMD.

The Intel Core i5-14490F is the stronger processor in raw compute across every recorded benchmark. The AMD processor remains an option for mobile platforms, integrated graphics needs, or ECC memory requirements, but the data shows no performance scenario where AMD overtakes Intel in the measured tests.

Head-to-Head Benchmarks

The Intel Core i5-14490F wins all 17 head-to-head benchmark comparisons. The most significant margin appears in PassMark physics, where Intel scores 2093 against AMD's 1208, a 42.3% advantage. This indicates a major difference in physics simulation performance, likely stemming from the higher core count and thread count.

PassMark find prime numbers shows Intel ahead by 40.2%, scoring 122 versus AMD's 73. Floating point math follows closely, with Intel at 66558 and AMD at 45481, a 31.7% difference. These results point to Intel's advantage in mathematically intensive workloads. Data compression also shows a clear gap: Intel scores 340026 versus AMD's 265826, a 21.8% difference.

The Cinebench suite reveals consistent 14.2% Intel advantages across all tests. In Cinebench R23 multicore, Intel scores 23000 versus AMD's 19742. Single-core R23 shows Intel at 3247 against AMD's 2787. The same 14.2% margin appears in R15 multicore (2318 vs 1989), R15 single-core (327 vs 280), R20 multicore (9660 vs 8291), and R20 single-core (1363 vs 1170). This uniform margin across generations of Cinebench suggests a consistent architectural performance advantage rather than workload-specific behavior.

PassMark multithread shows Intel at 28662 versus AMD's 23569, a 17.8% difference. Integer math follows with Intel at 87844 and AMD at 72740, a 17.2% margin. Data encryption is closer: Intel scores 18225 versus AMD's 17387, a 4.6% difference. Extended instructions show Intel at 21731 against AMD's 21212, only 2.4% ahead.

The narrowest margins appear in single-threaded tests and random string sorting. PassMark single-thread shows Intel at 3873 versus AMD's 3858, a mere 0.4% difference. Random string sorting also shows Intel ahead by 0.4%, scoring 35608 against AMD's 35472. These near-identical results indicate that for purely single-threaded tasks, the two processors perform essentially equally, with Intel's advantage growing as thread count utilization increases.

The overall pattern is clear: Intel dominates in multi-threaded workloads, holds a strong edge in floating point and prime number calculations, and matches AMD in single-threaded tasks. AMD's performance does not surpass Intel in any recorded test, and the Intel chip's higher average benchmark score of 38149 versus 30879 for AMD confirms its overall superiority in the measured data.
