AMD Ryzen 9 9955HX vs Intel Core 7 253PTE Comparison

Where Each One Wins

The benchmark data splits this comparison into two very different profiles. The AMD Ryzen 9 9955HX wins 14 of the 15 recorded head-to-head tests, while the Intel Core 7 253PTE takes a single victory. That one Intel win is in Cinebench R23 single-core, where the Intel part scores 3003 against the AMD part's 2174, a 27.6% advantage for Intel. Everything else falls to AMD.

The AMD processor dominates threaded workloads. In Cinebench R23 multi-core, the Ryzen 9 9955HX posts 37159 versus 21276 for the Intel Core 7 253PTE, a 74.7% gap. The Cinebench R15 multi-core test shows an even larger spread: 5905 against 2144, which is 175.4% ahead. PassMark multi-thread results follow the same pattern, with AMD at 56171 and Intel at 25031, a 124.4% difference. These numbers indicate that the AMD part is built for sustained parallel work, while the Intel chip struggles to keep pace when all cores are active.

Single-threaded results are closer, but AMD still leads in most tests. In PassMark single-thread, the Ryzen 9 9955HX scores 4393 versus 3794 for Intel, a 15.8% edge. Cinebench R15 single-core also favors AMD, 336 to 302, an 11.3% margin. The Intel part only wins in the Cinebench R23 single-core test, which suggests that Intel's architecture can deliver a strong burst in that specific workload, but it does not translate to a broader single-thread advantage across the PassMark suite.

Specialized instruction workloads heavily favor AMD. PassMark extended instructions show 57946 for AMD against 17099 for Intel, a 238.9% advantage. Prime number finding delivers 287 versus 82, a 250% gap. Data compression, encryption, floating point, integer math, physics, and random string sorting all go to AMD with margins ranging from 77.8% to 175.9%. The Ryzen 9 9955HX is the clear choice for compute-heavy tasks, while the Core 7 253PTE only shows a narrow edge in one specific Cinebench test.

Architecture Differences

The two processors come from different design philosophies and target different market segments. The AMD Ryzen 9 9955HX uses the Zen 5 architecture with the Fire Range codename, built on a 4 nm TSMC process with 16,630 million transistors and a dual-die design measuring 2x 70.6 mm². It is a mobile part in the 9000 series, released on 2025-01-05, and fits the AMD Socket FL1. The Intel Core 7 253PTE uses the Bartlett Lake codename, built on a 10 nm Intel process, and is a desktop part released on 2026-03-08, fitting the Intel Socket 1700.

Core configurations differ substantially. The AMD part offers 16 cores and 32 threads, while the Intel part provides 10 cores and 20 threads. Both have an 80 KB L1 cache per core, but the L2 cache differs: AMD has 1 MB per core, Intel has 2 MB per core. L3 cache also diverges, with AMD sharing 64 MB across the chip and Intel sharing 33 MB. The AMD part has a base clock of 2.50 GHz and a boost clock of 5.40 GHz, while the Intel part has a base clock of 1.80 GHz and the same 5.40 GHz boost. TDP ratings show 55 watts for AMD and 45 watts for Intel.

Memory support separates the two as well. The AMD processor supports DDR5 only with dual-channel access and 89.6 GB/s bandwidth. The Intel processor supports both DDR4 and DDR5, also dual-channel with 89.6 GB/s bandwidth. Both support ECC memory. PCIe lanes differ: AMD provides Gen 5 with 28 lanes from the CPU, while Intel provides Gen 5 with 16 lanes from the CPU. Integrated graphics are the Radeon 610M on the AMD side and UHD Graphics 730 on the Intel side.

The AMD multiplier is unlocked, allowing overclocking, while the Intel multiplier is locked. Process node, transistor count, die size, and foundry all favor AMD's more advanced manufacturing. The Intel part compensates with a larger per-core L2 cache and dual memory type support, but the core count and cache hierarchy give AMD a structural advantage in multi-threaded scenarios.

Head-to-Head Benchmarks

The largest single margin in the recorded data is PassMark find prime numbers, where AMD scores 287 and Intel scores 82, a 250% delta. This test is highly sensitive to integer execution efficiency and core count, and the Ryzen 9 9955HX's 16 cores overwhelm the Intel part's 10 cores. PassMark extended instructions shows a similar blowout: 57946 versus 17099, a 238.9% difference, indicating that AMD's Zen 5 handles vector and complex instruction sets far more effectively.

Cinebench R15 multi-core delivers a 175.4% advantage for AMD, with scores of 5905 and 2144. PassMark random string sorting follows at 175.9%, with 77890 against 28227. Data compression shows 731998 versus 275828, a 165.4% gap, and data encryption shows 37330 versus 15500, a 140.8% margin. These results cluster around the same theme: when the workload scales with core count, the AMD part pulls away by wide margins.

Mid-range deltas appear in PassMark multi-thread at 124.4%, floating point math at 103.4%, and physics at 106.4%. Integer math shows a 77.8% advantage, and Cinebench R23 multi-core shows 74.7%. These still represent substantial leads, but they are smaller than the extreme cases in prime finding and extended instructions.

The only Intel win is Cinebench R23 single-core, where the Core 7 253PTE scores 3003 against 2174, a 27.6% margin in Intel's favor. This is notable because Cinebench R15 single-core goes the other way, with AMD winning 336 to 302. The discrepancy suggests that the Intel part's boost behavior or architecture performs better in the newer Cinebench version's single-threaded workload, but this does not carry over to PassMark single-thread, where AMD wins 4393 to 3794, a 15.8% edge.

The Verdict

The recorded data presents a clear hierarchy. The AMD Ryzen 9 9955HX is the superior processor for almost every measured workload, with 14 wins out of 15 head-to-head benchmarks. Its 16-core, 32-thread configuration, larger L3 cache, and more advanced 4 nm process deliver massive advantages in multi-threaded, compression, encryption, math, and physics tests. The 250% lead in prime number finding and 238.9% lead in extended instructions demonstrate a fundamental execution efficiency gap that the Intel part cannot close.

The Intel Core 7 253PTE holds a single advantage in Cinebench R23 single-core, where it beats AMD by 27.6%. This indicates that the Bartlett Lake architecture can produce a strong single-thread burst in that specific test, and its 2 MB per-core L2 cache may contribute to that result. However, PassMark single-thread contradicts this, with AMD leading by 15.8%, so the Intel win does not represent a consistent single-thread superiority.

For workloads that scale across cores, the AMD Ryzen 9 9955HX is the clear choice. For users who prioritize the specific Cinebench R23 single-core metric, the Intel Core 7 253PTE offers a measurable edge, but the broader benchmark suite shows AMD ahead in every other category. The data supports AMD for general purpose and heavy compute tasks, while Intel's lone win is too narrow to offset the 14-loss record.
