AMD Ryzen 5 PRO 8645HS vs Intel Core 7 253PE Comparison

The AMD Ryzen 5 PRO 8645HS and Intel Core 7 253PE are two processors aimed at different segments, one a mobile chip and the other a desktop part. The data in the database shows a clear and consistent performance gap between them, with the Intel part taking the lead in nearly every recorded benchmark. This analysis walks through the head-to-head results, architecture, and specifications to clarify where each processor stands.

Head-to-Head Benchmarks

The benchmark results are overwhelmingly one-sided. Of the 17 recorded comparisons, the Intel Core 7 253PE wins 16, while the AMD Ryzen 5 PRO 8645HS secures a single victory. The margins vary widely, from narrow single-thread differences to large multi-core and math-oriented gaps.

Starting with the Cinebench suite, the Intel part leads across the board. In Cinebench R15 multi-core, the Intel processor scores 2507 against AMD’s 1989, a 20.7% deficit for the Ryzen chip. The single-core test tells a similar story: Intel scores 354, AMD scores 280, a 20.9% difference. Moving to Cinebench R20, the multi-core result is 10449 for Intel versus 8291 for AMD, again a 20.7% gap. The single-core R20 test shows Intel at 1475 and AMD at 1170, also a 20.7% difference. In Cinebench R23, the largest multi-core workload in the set, Intel scores 24880 while AMD manages 19742, a 20.7% margin. The R23 single-core test has Intel at 3512 and AMD at 2787, a 20.6% gap. These consistent percentages suggest a systematic performance advantage for the Intel part across all Cinebench versions.

The Passmark tests reveal where the biggest differences lie. The largest margin is in the prime number search test, where Intel scores 138 versus AMD’s 73, a 47.1% deficit for the Ryzen processor. Floating point math shows Intel at 80870 against AMD’s 45481, a 43.8% gap. Integer math follows with Intel scoring 114158 and AMD 72740, a 36.3% difference. Physics performance also favors Intel heavily: 1845 versus 1208, a 34.5% margin. Data compression shows Intel at 339133 and AMD at 265826, a 21.6% gap. Multithread performance has Intel at 29271 and AMD at 23569, a 19.5% difference.

The narrower margins appear in more specialized tasks. Data encryption shows Intel at 18385 and AMD at 17387, a 5.4% gap. Extended instructions show Intel at 21806 and AMD at 21212, a 2.7% difference. Single-thread performance, measured through Passmark, has Intel at 3955 and AMD at 3858, a 2.5% margin. Two identical single-thread entries appear in the data, both with the same scores.

The single AMD win comes in random string sorting. Here the Ryzen processor scores 35472 while Intel scores 32777. The delta is 8.2% in favor of AMD, making it the only test where the Intel part does not lead. This is a notable result because it shows the AMD chip can outperform in at least one specific memory or sorting workload, despite trailing in almost everything else.

Overall, the average benchmark score reflects this disparity. The Intel Core 7 253PE has an average score of 40557, placing it in the 87th percentile of all CPUs. The AMD Ryzen 5 PRO 8645HS has an average score of 30879, placing it in the 82nd percentile. The difference in average scores is substantial, roughly 31% higher for the Intel part.

The Verdict

The data points to a clear winner for most workloads. The Intel Core 7 253PE leads in every Cinebench test, all major Passmark math tests, data compression, encryption, extended instructions, physics, and multithread performance. The margins range from 2.5% to 47.1%, with the largest advantages in prime number search, floating point math, integer math, and physics. For users running rendering workloads, scientific calculations, or heavily threaded applications, the Intel processor is the stronger choice according to every recorded benchmark.

The AMD Ryzen 5 PRO 8645HS wins only in random string sorting, with an 8.2% advantage. This suggests the AMD chip may handle certain sorting or memory access patterns better, but the single data point does not offset the broad Intel lead. The Intel part also has a higher percentile ranking, 87th versus 82nd, and a much higher average score.

For a mobile user prioritizing low power and integrated graphics, the AMD part has its place, but the performance data does not favor it. The Intel processor delivers higher scores across nearly every category, with some margins exceeding 40%. The only scenario where the AMD chip appears preferable, strictly from the data, is when random string sorting performance is the primary concern. For virtually any other measured task, the Intel Core 7 253PE produces higher benchmark scores.

Architecture Differences

The two processors come from different design philosophies and manufacturing processes. The AMD Ryzen 5 PRO 8645HS uses the Zen 4 architecture under the Hawk Point codename. It is built on a 4 nm process at TSMC and contains 25,000 million transistors on a die size of 178 mm². The Intel Core 7 253PE uses the Bartlett Lake codename and is built on a 10 nm process at Intel. Its transistor count and die size are not recorded in the database.

Core counts differ significantly. The AMD processor has 6 cores and 12 threads. The Intel processor has 10 cores and 20 threads. This difference in core and thread counts likely explains much of the multi-core performance gap seen in Cinebench and Passmark multithread tests. The Intel part has more physical cores to distribute workloads across.

Cache hierarchies also differ. The AMD chip has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel chip has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The larger L3 cache on the Intel part, 33 MB versus 16 MB, may contribute to its advantage in data-heavy workloads.

Memory support shows a split. The AMD processor supports DDR5 only, while the Intel processor supports both DDR4 and DDR5. Both use a dual-channel memory bus, and both have a recorded memory bandwidth of 89.6 GB/s. ECC memory support is present on both processors.

PCIe capabilities differ. The AMD chip uses Gen 4 with 20 lanes (CPU only). The Intel chip uses Gen 5 with 16 lanes (CPU only). This means the Intel part offers a newer PCIe generation, though with fewer lanes.

Integrated graphics also differ. The AMD processor includes Radeon 760M graphics. The Intel processor includes UHD Graphics 730. The database does not provide benchmark scores for either integrated GPU, so a direct comparison of graphics performance is not possible from the recorded data.

The market segments differ as well. The AMD processor is classified as Mobile, while the Intel processor is classified as Desktop. This aligns with their sockets: AMD uses Socket FP7, and Intel uses Socket 1700. The release dates show the AMD part launched on April 15, 2024, while the Intel part has a later release date of March 8, 2026.

Where Each One Wins

The Intel Core 7 253PE wins in almost every category measured. The Cinebench suite, which tests rendering performance, shows a consistent 20.7% advantage across R15, R20, and R23 multi-core tests, with a slightly smaller 20.6% gap in R23 single-core. This makes the Intel part the clear choice for users running rendering or CPU-intensive creative workloads.

In Passmark math tests, the Intel part wins by even larger margins. Floating point math shows a 43.8% advantage, integer math a 36.3% advantage, and prime number search a 47.1% advantage. These results indicate the Intel processor handles computational workloads substantially better, which matters for scientific computing, financial modeling, or any number-crunching application.

The physics test shows a 34.5% lead for Intel, suggesting better performance in simulation or physics-based workloads. Data compression shows a 21.6% lead, and multithread performance a 19.5% lead. These wins cover most typical desktop workloads, from file compression to multitasking.

The AMD Ryzen 5 PRO 8645HS wins only in random string sorting, with an 8.2% advantage over the Intel part. This is a narrow win in a single test, but it does indicate that the AMD processor handles at least one specific data manipulation task better. For users whose primary workload involves sorting large sets of strings, the AMD chip might offer a small benefit. However, the broader dataset shows Intel leading in 16 other tests, so this single win does not change the overall picture.

The AMD processor also has advantages outside of benchmark scores that the data records. It is built on a smaller 4 nm process, uses less power at 45 W TDP versus 65 W for Intel, and is designed for mobile use. The Intel chip is a desktop part with a higher TDP. For users prioritizing power efficiency or mobile form factors, the AMD chip has structural advantages, but the performance data recorded in the database does not favor it in any major test except random string sorting.
