PCIe connectivity differs by generation. AMD uses PCIe Gen 3 with 16 CPU lanes, while Intel uses PCIe Gen 5 with 16 CPU lanes. Integrated graphics also differ: AMD includes Radeon Vega 7, while Intel includes UHD Graphics 770.

The sockets are incompatible. AMD uses Socket AM4, and Intel uses Socket 1700. The AMD part has a 65 W TDP, while the Intel part has a 45 W TDP. The AMD release date is recorded as 2024-05-06, while Intel's is 2025-01-12.

Head-to-Head Benchmarks

The Intel Core 7 251TE dominates the head-to-head results, winning 16 of 17 comparisons. The only AMD victory is in PassMark extended instructions, where the Ryzen 5 PRO 5655G scores 17944 versus 16974, a 5.7% margin.

Multi-core performance is decisively in Intel's favor. In Cinebench R23 multi-core, Intel scores 25518 against AMD's 17249, a 32.4% advantage. The same 32.4% delta appears in Cinebench R20 multi-core (10717 versus 7244) and Cinebench R15 multi-core (2572 versus 1738). This consistent gap across Cinebench versions indicates a stable multi-threaded advantage rather than a workload-specific artifact.

PassMark multi-thread shows a 36.3% lead for Intel with 30022 versus 19129. The floating point math test reveals an even larger gap: Intel scores 85607 versus 38649, a 54.9% advantage. Integer math shows Intel ahead by 46.3% with 125739 versus 67561. Data compression favors Intel at 334399 versus 255608, a 23.6% lead, and data encryption favors Intel at 22176 versus 15253, a 31.2% margin.

Prime number finding is heavily Intel-favored: 140 versus 49, a 65% deficit for AMD. Physics simulation shows a similar pattern with Intel at 1938 versus 686, a 64.6% gap. Random string sorting lands at 39643 for Intel versus 25253 for AMD, a 36.3% difference.

Single-thread performance is closer but still Intel-favored. PassMark single-thread shows 3568 versus 3241, a 9.2% lead. The Cinebench single-core tests show a wider margin: R23 single-core has Intel at 3602 versus 2435, R20 single-core has 1512 versus 1022, and R15 single-core has 362 versus 245, all with a 32.4% delta.

Where Each One Wins

The Intel Core 7 251TE is the clear winner for multi-threaded workloads. Its 24 cores and 32 threads deliver 32.4% higher Cinebench R23 multi-core scores and 36.3% higher PassMark multi-thread scores. Floating point math, integer math, prime number finding, physics simulation, data compression, and data encryption all favor Intel by margins ranging from 23.6% to 65%. The higher memory bandwidth of 89.6 GB/s and PCIe Gen 5 support further reinforce its position for heavily parallel tasks.

The AMD Ryzen 5 PRO 5655G wins only the PassMark extended instructions test by 5.7%. This specific result indicates an advantage in workloads that exercise specialized instruction sets, though the broader benchmark suite shows Intel ahead in nearly every other category. The AMD part also has a higher base clock of 3.90 GHz versus 1.40 GHz for Intel, though Intel's boost clock of 5.40 GHz exceeds AMD's 4.40 GHz.

For single-threaded responsiveness, the Intel part leads by 9.2% in PassMark single-thread and by 32.4% in Cinebench single-core tests. The AMD part's lower TDP of 65 W versus 45 W for Intel is notable, but the Intel part delivers higher performance across the board while consuming less rated power.

The overall benchmark distribution places the Intel Core 7 251TE at the 88th percentile of all CPUs, compared to the 80th percentile for the AMD Ryzen 5 PRO 5655G. The average benchmark score difference of 41650 versus 28032 confirms that the Intel part occupies a higher performance tier. The AMD processor's sole win in extended instructions suggests it may retain relevance for specific instruction-heavy applications, but the recorded data shows the Intel Core 7 251TE as the dominant processor in this comparison.
