AMD Ryzen 7 8745HX vs Intel Core 7 253PE Comparison

The Verdict

The AMD Ryzen 7 8745HX and Intel Core 7 253PE occupy different market positions, and the recorded benchmark data draws a clear line between them. The AMD processor wins 6 of the 11 head-to-head tests, while the Intel processor takes 5. However, the nature of those wins matters more than the raw count.

The Ryzen 7 8745HX is the stronger choice for security-related workloads, data compression, and memory-heavy tasks. Its wins include data encryption (18.8% ahead), extended instructions (26.7% ahead), and random string sorting (35.7% ahead). The Intel Core 7 253PE counters with dominance in floating-point math (23.4% ahead), integer math (12.1% ahead), and physics calculations (8.9% ahead). For single-thread performance, the Intel part edges ahead by 1.9%, a narrow margin that suggests near-parity in lightly threaded workloads.

The average benchmark score tells a different story. The Ryzen 7 8745HX posts an average of 60104, placing it in the 92nd percentile of all CPUs. The Intel Core 7 253PE averages 40557, sitting in the 87th percentile. This substantial gap in average score, roughly 48% higher for the AMD part, reflects the Ryzen's consistency across a broader range of tests. The Intel processor's nearest rival, the Intel Core 5 223PE, sits within 0.1% of its average score, while the AMD processor's closest competitor, the AMD Ryzen 9 7945HX, is essentially tied at a 0% delta.

For buyers focused on encryption, compression, and multi-threaded throughput, the Ryzen 7 8745HX is the data-backed pick. For those prioritizing floating-point math, integer operations, and physics simulations, the Intel Core 7 253PE delivers higher raw scores in those specific domains. The AMD part is also an unlocked multiplier processor, while the Intel part is locked, meaning the Ryzen offers overclocking headroom that the Intel cannot match.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 8745HX uses the Zen 4 architecture on a 5 nm TSMC process node, built around the Dragon Range codename. It packs 6,570 million transistors onto a 71 mm² die. The Intel Core 7 253PE uses the Bartlett Lake codename on a 10 nm Intel process, with no transistor count or die size recorded in the database.

Core configuration differs significantly. The AMD part has 8 cores and 16 threads, while the Intel part has 10 cores and 20 threads. Despite fewer cores, the AMD processor achieves higher multi-thread performance in the PassMark multithread test (31517 vs 29271, a 7.7% advantage). This suggests the Zen 4 cores extract more work per thread than the Intel cores in this workload.

Cache hierarchies also diverge. The AMD processor allocates 64 KB of L1 cache per core, 1 MB of L2 per core, and 32 MB of shared L3. The Intel processor allocates 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The larger per-core L1 and L2 on the Intel side may contribute to its advantages in integer and floating-point math, while the AMD part's smaller cache configuration still manages to win in memory-sensitive tests.

Memory support shows a clear split. The AMD processor supports only DDR5, while the Intel processor supports both DDR4 and DDR5. The Intel part also claims slightly higher memory bandwidth at 89.6 GB/s versus 83.2 GB/s for the AMD part. Notably, the Intel processor supports ECC memory, while the AMD processor does not. This makes the Intel part more suitable for error-sensitive workloads.

PCIe connectivity favors the AMD processor. It offers Gen 5 with 28 lanes (CPU only), while the Intel part offers Gen 5 with 16 lanes (CPU only). The AMD processor also uses AMD Socket FL1, designed for mobile platforms, while the Intel part uses Intel Socket 1700, a desktop socket. The market segment field confirms this: the Ryzen 7 8745HX is marked as Mobile, while the Core 7 253PE is marked as Desktop.

The integrated graphics differ as well. The AMD processor uses Radeon 610M, while the Intel processor uses UHD Graphics 730. Neither chip's iGPU performance appears in the benchmark data, so no direct comparison is possible from the recorded scores.

Clock speeds tell a nuanced story. The AMD part has a higher base clock at 3.60 GHz versus 2.50 GHz for the Intel part, but the Intel part has a higher boost clock at 5.50 GHz versus 5.10 GHz. The TDP also favors the AMD part at 55 watts versus 65 watts for the Intel part, suggesting better power efficiency per watt.

Release dates differ by nearly a year. The AMD processor launched on 2025-04-22, while the Intel processor launched on 2026-03-08. The Intel part carries a launch MSRP of $384, while the AMD part has no recorded launch MSRP.

Head-to-Head Benchmarks

The recorded head-to-head data reveals a clear pattern of workload-dependent superiority. The AMD Ryzen 7 8745HX dominates in memory-heavy and security-oriented tasks, while the Intel Core 7 253PE excels in arithmetic-heavy and physics-based workloads.

The largest AMD victory comes in random string sorting, where the Ryzen 7 8745HX scores 44494 against 32777 for the Intel part, a 35.7% advantage. This test stresses memory access patterns and cache behavior, areas where the AMD part's architecture proves more efficient despite smaller per-core caches. Extended instructions follow closely, with the AMD part scoring 27638 versus 21806, a 26.7% lead. Data encryption also favors AMD by 18.8%, with scores of 21840 and 18385 respectively.

The AMD processor also wins in find prime numbers (159 vs 138, a 15.2% lead), multi-thread performance (31517 vs 29271, a 7.7% lead), and data compression (363759 vs 339133, a 7.3% lead). These results indicate that the AMD part translates its lower core count into superior throughput in tasks that rely on efficient thread scheduling and memory bandwidth utilization.

The Intel Core 7 253PE counters with its largest win in floating-point math, scoring 80870 against 61972 for the AMD part, a 23.4% advantage. Integer math also favors Intel by 12.1%, with scores of 114158 and 100328 respectively. Physics calculations go to Intel by 8.9%, with scores of 1845 and 1681. Single-thread performance narrowly favors Intel at 3955 versus 3879, a 1.9% margin.

These Intel wins suggest that the Bartlett Lake architecture handles arithmetic-heavy workloads particularly well, likely benefiting from its larger per-core L1 and L2 caches and higher boost clock of 5.50 GHz. The physics score advantage, while modest, indicates better raw computational throughput in simulation-style workloads.

The overall win count stands at 6 for AMD and 5 for Intel, but the average benchmark score gap of 60104 versus 40557 tells a broader story. The AMD processor achieves this higher average despite losing several individual tests, meaning its wins are larger in magnitude than its losses. The Intel part's winning margins in floating-point and integer math, while substantial, do not compensate for the AMD part's larger advantages in memory-intensive and security-related tasks.

The percentile rankings corroborate this interpretation. The AMD part sits at the 92nd percentile of all CPUs, while the Intel part sits at the 87th. This 5-percentile gap reflects the AMD processor's stronger overall standing in the database. The nearest rivals for each processor also confirm their respective tiers: the AMD part trades blows with the AMD Ryzen 9 7945HX (0% delta) and Intel Core i9-14900F (0.2% delta), while the Intel part sits alongside the Intel Core 5 223PE (-0.1% delta) and AMD Ryzen 9 7940HX (0.3% delta). The AMD part competes in a higher performance class, despite both processors being listed as active production parts.
