AMD Ryzen 5 PRO 8640HS vs Intel Core 7 251TE Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear overall victory for the Intel Core 7 251TE, which wins 16 of the 17 head-to-head comparisons. The single exception is the PassMark extended instructions test, where the AMD Ryzen 5 PRO 8640HS takes the win by 9%, scoring 18,507 against 16,974. That is the only test where the AMD part leads, and it is a narrow margin compared to the scale of Intel's other victories.

The most lopsided results come from floating point math and physics workloads. In the PassMark floating point math test, the Intel Core 7 251TE scores 85,607 versus 43,019 for the AMD, a delta of -49.7% from AMD's perspective. The physics test shows a nearly identical pattern: Intel scores 1,938 while AMD manages 1,043, a 46.2% gap. Integer math also favors Intel heavily, with 125,739 against 69,839, a 44.5% difference. These three tests are the largest deltas in the entire dataset and indicate a substantial advantage in raw computational throughput.

The Cinebench suite tells a consistent story. Across R15, R20, and R23, the Intel part leads by roughly 29% in both single-core and multi-core runs. In Cinebench R23 multi-core, Intel scores 25,518 versus AMD's 18,104, a delta of -29.1%. Single-core R23 shows the same pattern: 3,602 for Intel against 2,555 for AMD, also -29.1%. The R15 and R20 results mirror this exactly, with deltas of -29.1% for multi-core and -29% for single-core. This consistency across three Cinebench generations suggests the gap is structural rather than workload-specific.

PassMark multithreaded performance follows the same trend. Intel scores 30,022 against AMD's 21,465, a 28.5% advantage. Data compression and encryption also favor Intel: 334,399 versus 246,446 for compression (-26.3%) and 22,176 versus 14,962 for encryption (-32.5%). Random string sorting shows a smaller but still clear gap at -23.7%, with Intel posting 39,643 against 30,235.

The closest contest is in PassMark single-thread performance. Intel scores 3,568 and AMD scores 3,561, a difference of only 0.2%. This is the only head-to-head where the two processors are effectively tied. The Prime numbers test is also lopsided in Intel's favor, 140 versus 71, a delta of -49.3%, indicating a strong advantage in this particular integer workload.

Where Each One Wins

The AMD Ryzen 5 PRO 8640HS has exactly one benchmark win: extended instructions. The 9% lead in that test suggests the Zen 4 architecture handles certain instruction-set extensions more efficiently than the Intel part. For users running workloads that rely heavily on extended instruction sets, this is the only area where the AMD chip shows an edge.

The Intel Core 7 251TE wins everywhere else. Its strongest areas are floating point math, physics simulation, and integer math, where it leads by 44% to 50%. These are classic indicators of strong multi-core throughput, and the Cinebench results confirm that the advantage extends to rendering and general compute workloads. The consistent 29% lead across all three Cinebench versions means the Intel part is reliably faster in both lightly threaded and heavily threaded rendering tasks.

Data compression and encryption also belong to Intel, with leads of 26.3% and 32.5% respectively. These workloads benefit from the higher core count and thread count of the Intel chip. The random string sorting test, another multi-threaded workload, shows a 23.7% lead for Intel. Prime number calculation is even more lopsided at 49.3%, suggesting Intel's integer execution capabilities are significantly stronger.

Single-thread performance is effectively a draw. The 0.2% difference in PassMark single-thread scores is within measurement noise. This means that for purely single-threaded tasks, neither processor has a meaningful advantage over the other. The Intel part's boost clock of 5.40 GHz does not translate into a real-world single-thread win in this dataset, despite being higher than AMD's 4.90 GHz.

Architecture Differences

The AMD Ryzen 5 PRO 8640HS is built on TSMC's 4 nm process and uses the Zen 4 architecture with the Hawk Point codename. 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, and it uses the AMD Socket FP7. The die size is 178 mm² with 25,000 million transistors. Cache consists of 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3.

The Intel Core 7 251TE is a different class of part. It uses Intel's 10 nm process, the Bartlett Lake codename, and a 24-core, 32-thread configuration. Base clock is 1.40 GHz, boost clock is 5.40 GHz, and TDP is 45 watts. It fits the Intel Socket 1700. The die size is 215 mm². Cache is larger across the board: 80 KB of L1 per core, 1.25 MB of L2 per core, and 36 MB of shared L3. The Intel part also supports both DDR4 and DDR5 memory, while the AMD part supports DDR5 only. Both support dual-channel memory with identical bandwidth of 89.6 GB/s, and both support ECC memory.

PCIe support differs significantly. The AMD part offers Gen 4 with 20 lanes (CPU only), while the Intel part offers Gen 5 with 16 lanes (CPU only). The integrated graphics also differ: AMD uses the Radeon 760M, Intel uses UHD Graphics 770. The AMD part is classified as a mobile processor, while the Intel part is a desktop processor. The Intel part was released on 2025-01-12, roughly nine months after the AMD part's release on 2024-04-15. The Intel part has a launch MSRP of $384. The AMD part has no recorded launch MSRP in the database.

The Verdict

The data supports the Intel Core 7 251TE for anyone prioritizing multi-core performance. It wins 16 of 17 benchmarks, with leads ranging from 23.7% to 49.7% across the most demanding workloads. The 24-core, 32-thread configuration delivers results that the 6-core, 12-thread AMD part cannot match in rendering, physics, integer math, or encryption. The 29% lead across all three Cinebench versions is particularly telling for productivity and content creation workloads.

The AMD Ryzen 5 PRO 8640HS is the better choice only for workloads that depend on extended instruction sets, where it leads by 9%. Its 28-watt TDP also makes it a lower-power part, though the database does not include power consumption measurements. For users who need a mobile processor with ECC memory support and a modest core count, the AMD part is a valid option. The Intel part is a desktop processor with a 45-watt TDP and a higher launch MSRP of $384.

The overall benchmark average confirms the gap. The Intel part scores 41,650 in the database's average benchmark metric, placing it in the 88th percentile of all CPUs. The AMD part scores 28,478, placing it in the 80th percentile. The nearest rivals for each part reinforce the positioning: the Intel Core 7 251TE sits alongside the Intel Core i7-14650HX and Intel Core i7-14700T among its closest competitors, while the AMD Ryzen 5 PRO 8640HS is bracketed by the Intel Xeon E-2436 and AMD Ryzen 7 PRO 6850HS.

For single-threaded tasks, the choice does not matter: the two parts are effectively tied in PassMark single-thread performance. For anything multi-threaded, the Intel part is the clear winner based on the recorded data.
