The AMD Ryzen 5 PRO 8640U and Intel Core 7 253PQE occupy different corners of the processor market, with the former built for mobile efficiency and the latter aimed at desktop performance. The benchmark data records a decisive sweep: the Intel part wins all 17 head-to-head tests, while the AMD part records zero wins. The average benchmark score for the AMD Ryzen 5 PRO 8640U is 30254, placing it in the 81st percentile of all CPUs. The Intel Core 7 253PQE averages 55919, sitting in the 91st percentile. These figures frame a comparison where the Intel chip leads by a wide margin, but the AMD chip is no slouch in its own segment.

Where Each One Wins

The Intel Core 7 253PQE wins every recorded benchmark, so the use-case split is one-sided. The largest deltas appear in compute-heavy workloads. In PassMark floating point math, the Intel part scores 105279 versus 45265 for the AMD, a delta of -57% from the AMD perspective. Integer math shows 137795 against 74875, a -45.7% gap. The find prime numbers test records 206 for Intel and 78 for AMD, a -62.1% delta, indicating a strong lead in algorithmic integer workloads. Physics simulation in PassMark shows 2970 versus 1154, a -61.1% delta. These results indicate the Intel processor is better suited for number-crunching tasks, scientific simulations, and any workload that stresses raw arithmetic throughput.

The AMD Ryzen 5 PRO 8640U, while losing all head-to-head tests, still delivers respectable scores for a 28-watt mobile processor. Its best relative showing comes in PassMark single-thread, where it scores 3732 against Intel's 4389, a -15% delta. This is the narrowest gap in the entire comparison. For single-threaded responsiveness, the AMD chip is closer to parity, though still behind. The data suggests the AMD part wins no workload category outright, but its efficiency-oriented design keeps it competitive in lighter tasks.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen 5 PRO 8640U is built on Zen 4 architecture with the Hawk Point codename, fabricated on a 4 nm process at TSMC. It has 6 cores and 12 threads, with a base clock of 3.50 GHz and a boost clock of 4.90 GHz. The thermal design power is 28 watts. The Intel Core 7 253PQE uses the Bartlett Lake codename with a 10 nm process at Intel, featuring 10 cores and 20 threads, a base clock of 3.50 GHz, and a boost clock of 5.70 GHz. Its TDP is 125 watts.

Cache configurations diverge sharply. The AMD part has 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The Intel part has 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. The Intel chip carries more total cache at every level, which contributes to its higher throughput in cache-sensitive workloads. The AMD chip uses a smaller die at 178 mm² with 25,000 million transistors, while the Intel chip has no recorded die size or transistor count in the database.

Memory support differs as well. The AMD processor supports DDR5 only, with dual-channel memory and 89.6 GB/s bandwidth. The Intel processor supports both DDR4 and DDR5, also dual-channel with the same 89.6 GB/s bandwidth. Both support ECC memory. PCIe connectivity differs: the AMD part uses Gen 4 with 20 lanes (CPU only), while the Intel part uses Gen 5 with 16 lanes (CPU only). Integrated graphics also differ, with the AMD using Radeon 760M and the Intel using UHD Graphics 770.

The sockets are incompatible: AMD uses Socket FP7, while Intel uses Socket 1700. The AMD part targets the mobile segment, while the Intel part is a desktop processor. Release dates are distinct too, with the AMD launched in 2024-04-15 and the Intel in 2026-03-08. The Intel part has a launch MSRP of $409.

The Verdict

The data points to clear roles for each processor. The Intel Core 7 253PQE is the stronger performer across every measured benchmark. Its 10 cores and 20 threads, combined with a 5.70 GHz boost clock and 33 MB L3 cache, deliver scores that place it near the top of the database. It sits at the 91st percentile and its average benchmark score of 55919 puts it within 0.2% of the Intel Core i9-14900HX, and within 1.1% of the AMD Ryzen Threadripper PRO 3955WX. For workloads that demand maximum multi-threaded performance, desktop compute, or high-clock single-thread speed, the Intel part is the clear choice based on the recorded data.

The AMD Ryzen 5 PRO 8640U, with a 28-watt TDP and 4 nm process, is designed for mobile use. Its 6 cores and 12 threads, plus a 4.90 GHz boost clock, produce an average score of 30254, sitting at the 81st percentile. It trails the Intel part by 45.3% in PassMark multithread (22795 versus 41656) and by 36.3% in Cinebench R23 multicore (19982 versus 31390). The AMD part is competitive with its nearest rivals, showing a 0.1% delta against the AMD Ryzen 7 2700X and a -0.4% delta against the AMD Ryzen 7 7736U. For systems prioritizing portability and energy efficiency, the AMD chip has a place, but for raw performance, the Intel part dominates.
