AMD Ryzen 7 5700X vs Intel Core Ultra 5 125H Comparison

The AMD Ryzen 7 5700X and Intel Core Ultra 5 125H occupy the same performance tier—both hold the 79th percentile among all CPUs and post nearly identical average benchmark scores (27578 vs. 27507). The Ryzen 7 5700X edges ahead with a 0.3% higher average score, but the head-to-head data reveals a more complex story: one processor dominates productivity and compute workloads, while the other claims victory in specific single-threaded and physics-based tests. This analysis breaks down the exact benchmark deltas, architectural foundations, and use-case implications of these two contenders.

Head-to-Head Benchmarks

The Ryzen 7 5700X wins 11 of the 15 shared benchmark comparisons, and several victories are decisive. In PassMark data encryption, the AMD part scores 20198 against the Intel's 14251, a 41.7% advantage. The gap widens further in PassMark extended instructions: 21755 vs. 13749, a 58.2% delta that represents the largest single margin in the comparison. PassMark integer math also favors AMD heavily, with 92749 versus 69986 (32.5% ahead). The Ryzen's data compression score of 323610 outstrips the Core Ultra's 236209 by 37%, and its prime number finding result of 119 beats 88 by 35.2%. Even in PassMark multithread, AMD holds a 26.1% lead (26612 vs. 21100), and random string sorting favors the Ryzen by 22.2% (33512 vs. 27435).

Cinebench results are closer but still favor AMD in multi-core workloads. In Cinebench R15 multicore, the Ryzen 7 5700X scores 2329 against 2021.5, a 15.2% win. Cinebench R23 multicore narrows the gap to 3% (13184 vs. 12804.5). The single-core Cinebench R15 result also goes to AMD, 253 vs. 241, a 5% margin. The floating-point math test is essentially a tie: 51842 vs. 51670, with AMD winning by 0.3%.

The Intel Core Ultra 5 125H claims four wins, but three are marginal. PassMark single-thread (and its duplicate singlethread result) gives Intel a 3399 vs. 3385 edge, a mere 0.4% difference. PassMark physics is a more meaningful Intel victory: 1439 vs. 1337, a 7.1% advantage. The most significant Intel win comes in Cinebench R23 single-core, where the Core Ultra scores 1647.5 versus 1499, a 9% lead. Notably, Intel does not have a Cinebench R15 single-core loss of the same magnitude—the AMD part wins that test by 5%—but the R23 single-core result demonstrates genuine Intel strength in lightly threaded rendering workloads.

Architecture Differences

The two processors represent fundamentally different design philosophies. The AMD Ryzen 7 5700X is a desktop part built on the Zen 3 architecture (codename Vermeer), manufactured on TSMC's 7 nm process. It packs 8 cores and 16 threads with a base clock of 3.40 GHz and boost clock of 4.60 GHz. The Intel Core Ultra 5 125H is a mobile processor using the Meteor Lake architecture, also on a 7 nm node but fabricated by Intel's own foundry. It offers 14 cores and 18 threads, reflecting a hybrid configuration, with a base clock of 3.60 GHz and boost clock of 4.50 GHz. Despite having more cores, the Intel part's thread count (18) is only 2 higher than AMD's (16), suggesting the hybrid core arrangement does not scale thread count linearly with core count.

Cache hierarchies differ substantially. The Ryzen 7 5700X features 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3 cache. The Core Ultra 5 125H has larger per-core caches—112 KB L1 and 2 MB L2 per core—but a smaller 18 MB shared L3. The AMD part's larger L3 cache likely contributes to its significant lead in data compression and encryption workloads, which benefit from larger shared pools. Memory support also diverges: the Ryzen uses DDR4 with dual-channel bandwidth of 51.2 GB/s and supports ECC memory, while the Intel part supports DDR5 with dual-channel bandwidth of 89.6 GB/s but lacks ECC support. The Intel memory bandwidth advantage is substantial (89.6 vs. 51.2 GB/s), yet it does not translate into wins in the bandwidth-sensitive PassMark tests.

PCIe connectivity differs: the Ryzen 7 5700X provides Gen 4 with 20 lanes (CPU only), while the Core Ultra 5 125H supports Gen 5. The Intel part includes integrated Arc Xe-LPG 96EU graphics, whereas the AMD processor has no integrated graphics. The Ryzen uses the AMD Socket AM4 and has an unlocked multiplier; the Intel uses Intel BGA 2049 and is locked. The AMD processor launched on 2022-04-03 with a launch MSRP of $299; the Intel part launched on 2023-12-13 with a launch MSRP of $375.

Where Each One Wins

The Ryzen 7 5700X is the clear choice for compute-intensive desktop workloads. Its 58.2% lead in extended instructions and 41.7% advantage in data encryption make it superior for cryptography, compression, and scientific computing tasks. The 37% win in data compression and 32.5% lead in integer math reinforce this profile. For multi-threaded productivity, the 26.1% PassMark multithread advantage and 3% Cinebench R23 multicore win indicate consistent strength across rendering and general parallel workloads. The 15.2% Cinebench R15 multicore margin is particularly notable, suggesting the AMD part scales better in some legacy multi-core benchmarks.

The Intel Core Ultra 5 125H wins in specific areas that matter for mobile and light-threaded use cases. Its 9% lead in Cinebench R23 single-core is the largest Intel victory and indicates superior single-thread rendering performance. The 7.1% win in PassMark physics suggests better performance in physics simulation workloads. The 0.4% PassMark single-thread margin is negligible but still represents a win. With its integrated graphics and 28W TDP (versus AMD's 65W TDP), the Core Ultra is positioned for thin-and-light laptops where power efficiency and GPU capability matter more than raw compute throughput. The Intel part's DDR5 support and higher memory bandwidth (89.6 GB/s) also make it better suited for memory-bandwidth-sensitive mobile workloads, even though the benchmark data shows AMD winning most memory-related tests.
