AMD Ryzen 9 PRO 6950HS vs Intel Core Ultra 7 155H Comparison

Where Each One Wins

The benchmark data splits these two mobile processors into distinct roles. The Intel Core Ultra 7 155H takes the majority of the head-to-head wins, claiming 11 of the 15 recorded comparisons. Its victories are concentrated in heavily multithreaded rendering workloads, physics simulation, and floating-point math. The AMD Ryzen 9 PRO 6950HS counters with 4 wins, all in specialized data processing tasks: compression, encryption, extended instruction sets, and integer math.

For content creation and general productivity, the Intel part is the clear leader. The Cinebench results show a substantial gap in both multi-core and single-core rendering performance. The Intel chip also dominates in PassMark physics tests, which often correlates with gaming and simulation workloads. The AMD processor, however, retains an edge in security-related tasks and data handling. Its 9% lead in data encryption and 1.9% lead in data compression suggest it handles cryptographic workloads and archive management more efficiently.

The overall average benchmark scores reflect this split. The Intel Core Ultra 7 155H posts an average score of 32697, placing it in the 83rd percentile of all CPUs. The AMD Ryzen 9 PRO 6950HS averages 31850, sitting in the 82nd percentile. The Intel chip's nearest rival, the Intel Core i5-14600T, matches it exactly at 32707 with a 0% delta. The AMD chip's closest competitor, the Intel Core i5-14450HX, scores 32040, a mere 0.6% difference. These figures place both processors in the same performance tier, but with different strengths.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 9 PRO 6950HS uses the Zen 3+ architecture on the Rembrandt codename, built on a 6 nm process at TSMC. It features 8 cores and 16 threads, a configuration that relies on simultaneous multithreading to handle parallel workloads. The Intel Core Ultra 7 155H uses the Meteor Lake architecture, built on a 7 nm process at Intel. It offers 16 cores and 22 threads, a hybrid design that mixes performance and efficiency cores.

The cache hierarchies differ significantly. The AMD chip provides 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The Intel chip offers 112 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The larger L3 cache on the Intel part gives it more headroom for data-heavy workloads, while the AMD design's smaller per-core L1 and L2 caches reflect its older architecture.

Memory support also diverges. Both use dual-channel DDR5, but the Intel chip supports a higher memory bandwidth of 89.6 GB/s compared to the AMD chip's 76.8 GB/s. The PCIe connectivity differs as well: the AMD processor uses Gen 4 with 20 lanes, while the Intel processor uses Gen 5 with 8 lanes. The integrated graphics are distinct, with the AMD chip featuring Radeon 680M and the Intel chip featuring Arc Xe-LPG 128EU.

The base and boost clocks tell a story of different power strategies. The AMD chip has a base clock of 3.30 GHz and a boost of 4.90 GHz. The Intel chip has a higher base of 3.80 GHz but a slightly lower boost of 4.80 GHz. The TDP ratings differ, with the AMD part rated at 35 watts and the Intel part at 28 watts. The Intel chip's lower TDP combined with its higher core count suggests a more efficient hybrid design.

Head-to-Head Benchmarks

The Cinebench results show the Intel Core Ultra 7 155H's dominance in rendering. In Cinebench R23 multi-core, the Intel chip scores 15028 against the AMD chip's 11515, a 23.4% advantage. The single-core R23 test shows a 13.1% lead for Intel, with scores of 1743 versus 1514. The older Cinebench R15 tests follow the same pattern: Intel leads by 21.9% in multi-core (2450 vs 1913) and 6.3% in single-core (255 vs 239).

The PassMark physics test reveals the largest gap in the entire dataset. The Intel chip scores 1727, while the AMD chip manages only 1043, a 39.6% deficit. This is a massive difference that suggests the Intel architecture handles physics calculations far more efficiently. The floating-point math test also favors Intel significantly, with a score of 63703 versus 48096, a 24.5% lead.

The AMD Ryzen 9 PRO 6950HS fights back in specific areas. Its biggest win comes in extended instructions, where it scores 18897 against Intel's 16456, a 14.8% advantage. The data encryption test shows a 9% lead for AMD (17837 vs 16358). The compression test is closer, with AMD winning 282624 to 277353, a 1.9% margin. The integer math test also goes to AMD, 88124 to 86870, a 1.4% edge.

The remaining tests are closer. The PassMark multi-thread test goes to Intel, 24873 to 22775, an 8.4% lead. Random string sorting favors Intel by 8.3% (31990 vs 29350). The single-thread tests show a narrow Intel advantage of 2% (3468 vs 3400). The find prime numbers test is a notable outlier: Intel scores 113 against AMD's 56, a 50.4% difference that represents the largest relative gap in either direction.
