The benchmark data shows a decisive overall victory for the AMD Ryzen Threadripper PRO 9955WX, which wins 13 of the 17 recorded head-to-head comparisons. The Intel Core Ultra 7 270HX Plus takes four wins, all of them in PassMark workloads, but the magnitude and distribution of the AMD wins demonstrate a clear performance hierarchy.

The largest AMD advantage appears in PassMark extended instructions, where the Threadripper PRO 9955WX scores 76363 against 39283 for the Intel part, a delta of 94.4%. This is closely followed by PassMark integer math, where AMD leads 236120 to 122449, a 92.8% margin. The data compression test shows an 86.7% gap, with AMD scoring 920954 versus 493179. Random string sorting favors AMD by 66.3%, with scores of 99813 and 60020 respectively. These four workloads, all heavily dependent on raw compute throughput, highlight the AMD processor's substantial advantage in parallel integer and data-manipulation tasks.

The Cinebench suite shows a consistent and uniform AMD lead. Across all six Cinebench tests, the delta is either 41.9% or 42.0%. In Cinebench R23 multicore, AMD scores 59494 against 41913, a 41.9% advantage. The single-core R23 result shows 8399 versus 5917, also a 41.9% gap. The same relationship holds in R20 multicore (24987 vs 17603) and R20 single-core (3527 vs 2485), as well as R15 multicore (5996 vs 4224) and R15 single-core (846 vs 596). The consistency of this margin across all three Cinebench versions, both single and multi-threaded, indicates a fundamental architectural performance advantage rather than a workload-specific anomaly. The Threadripper PRO 9955WX also leads in PassMark multithread by 38.9%, scoring 67035 against 48270, and in PassMark physics by 8.1%, with 4156 versus 3843. Data encryption favors AMD by 17.4%, with scores of 44389 and 37813.

The Intel Core Ultra 7 270HX Plus secures its wins in more narrowly defined workloads. The largest Intel victory is in PassMark find prime numbers, where it scores 482 against AMD's 337, a 30.1% advantage. This is a notable result, as prime-number finding often scales with specific instruction-level efficiency rather than raw core count. Intel also wins PassMark floating point math by 4.5%, scoring 163567 versus 156215. The PassMark single-thread test, recorded identically as passmark_single_thread and passmark_singlethread, shows Intel ahead 4764 to 4530, a 4.9% margin. This single-thread result is significant because it demonstrates that the Intel mobile processor can outperform the AMD workstation part in lightly threaded scalar work, even though AMD dominates the Cinebench single-core tests by nearly 42%. The divergence between Cinebench R23 single-core and PassMark single-thread suggests different instruction mixes and possibly different thermal or power behavior during short bursts versus sustained loads.

The average benchmark scores reflect the overall gap. The AMD processor records an average benchmark score of 101041, while the Intel processor averages 61834. The AMD part sits at the 97th percentile among all CPUs in the database, while the Intel part is at the 93rd percentile. The AMD processor's nearest rivals in the database are server-class EPYC parts: the EPYC 7513 (average score 102244, delta of -1.2%), the EPYC 8324P (103329, -2.2%), the EPYC 4585PX (99324, +1.7%), and the Threadripper PRO 5965WX (98504, +2.6%). This places the 9955WX in a performance tier occupied by dual-socket server processors. The Intel Core Ultra 7 270HX Plus, by contrast, sits alongside desktop Core i9 parts, with its closest rivals being the Core i9-13900KF (61841, 0% delta), the Core i9-13900K (61766, +0.1%), the Core i9-13900T (61723, +0.2%), and the Xeon 636 (61360, +0.8%). These rival groupings show that the two processors in this comparison are not competing in the same market segment, despite the head-to-head benchmark overlap.

Where Each One Wins

The AMD Ryzen Threadripper PRO 9955WX is the clear choice for heavily parallel compute workloads. Its wins span all six Cinebench tests, with a uniform 41.9% to 42.0% margin across both single and multi-threaded versions. The PassMark results reinforce this pattern: multithread (38.9% ahead), integer math (92.8% ahead), extended instructions (94.4% ahead), data compression (86.7% ahead), random string sorting (66.3% ahead), data encryption (17.4% ahead), and physics (8.1% ahead). This workload profile suggests strength in rendering, simulation, encryption, compression, and any task that can utilize many threads with high integer throughput. The 16-core, 32-thread configuration with a 5.40 GHz boost clock provides the foundation for these results.

The Intel Core Ultra 7 270HX Plus wins in a narrower set of tasks. Its 30.1% advantage in PassMark find prime numbers indicates an efficiency in specific mathematical routines that may benefit from its architecture's instruction handling. The 4.5% win in floating point math and the 4.9% win in PassMark single-thread show that Intel retains a measurable edge in certain scalar and floating-point workloads. For users whose primary applications involve prime-number searches, specific floating-point simulations, or lightly threaded tasks where the PassMark single-thread metric is representative, the Intel part demonstrates a meaningful advantage. However, these wins are concentrated and do not offset the broad AMD dominance across the majority of recorded tests.

The overall win count stands at 13 for AMD and 4 for Intel. The average benchmark scores, 101041 versus 61834, place the two processors in very different performance tiers, with AMD's closest rivals being server-class EPYC processors and Intel's being desktop Core i9 parts. The choice between these two hinges on workload priority: AMD for sustained multi-threaded throughput across diverse workloads, Intel for specific scalar and floating-point tasks where its targeted wins apply.

Specification Differences

The two processors differ substantially in core configuration and power envelope. The AMD Ryzen Threadripper PRO 9955WX has 16 cores and 32 threads, while the Intel Core Ultra 7 270HX Plus has 20 cores and 20 threads. The Intel part has more physical cores but no hyperthreading, resulting in fewer threads than the AMD part. Base clocks differ significantly: AMD runs at 4.50 GHz, while Intel runs at 2.40 GHz. Boost clocks are closer, with AMD at 5.40 GHz and Intel at 5.30 GHz.

The thermal design power (TDP) figures show a massive difference. The AMD processor is rated at 350 watts, while the Intel processor is rated at 55 watts. This reflects their different market segments: the AMD part is a desktop workstation processor, while the Intel part is a mobile processor. The socket types also differ, with AMD using AMD Socket sTR5 and Intel using Intel BGA 2114. The memory bus configuration diverges sharply: AMD supports eight-channel memory with a bandwidth of 409.6 GB/s, while Intel supports dual-channel memory with a bandwidth of 102.4 GB/s. Both support DDR5 memory, but AMD includes ECC memory support while Intel does not.

PCIe connectivity differs as well. The AMD processor provides Gen 5 with 128 lanes (CPU only), while the Intel processor provides Gen 5 with 20 lanes (CPU only). The AMD part has no integrated graphics, while the Intel part includes Arc Xe-LPG Graphics 64EU. The launch MSRP for the AMD processor is $1649; no launch MSRP is recorded for the Intel part. Both processors have unlocked multipliers. The market segments confirm the positioning: AMD is listed as Desktop, Intel as Mobile. The release dates also differ, with the AMD processor released on 2025-07-22 and the Intel processor on 2026-03-16.

Architecture Differences

The architectural foundations of these two processors are distinct. The AMD Ryzen Threadripper PRO 9955WX uses the Zen 5 architecture with the codename Shimada Peak, belonging to the Ryzen Threadripper generation listed as Zen 4 (Storm Peak). The Intel Core Ultra 7 270HX Plus uses the Arrow Lake-HX Refresh codename, belonging to the Core Ultra Series 2 generation listed as Ultra 7 (Arrow Lake-HX). The Intel processor's architecture field is recorded as null, indicating no specific microarchitecture name is assigned in the database.

The manufacturing process nodes differ, with AMD using a 4 nm process and Intel using a 3 nm process. Both are fabricated by TSMC. Transistor counts are similar in scale: the AMD processor has 16,630 million transistors across a die size of 2x 70.6 mm², while the Intel processor has 17,800 million transistors on a single 243 mm² die. The AMD design uses a multi-die configuration with two chiplets, while the Intel part uses a monolithic die.

Cache hierarchies are organized differently. The AMD processor provides 64 KB of L1 cache per core and 1 MB of L2 cache per core, with a 64 MB L3 cache. The Intel processor provides 192 KB of L1 cache per core and 3 MB of L2 cache per core, with a 30 MB shared L3 cache. The larger per-core caches on the Intel side are offset by the larger total L3 cache on the AMD side. Neither processor has 3D V-Cache. The recorded total L3 values are null for both, so only the per-core and shared cache figures are available for comparison.

The AMD processor's eight-channel memory bus with 409.6 GB/s bandwidth is a defining architectural feature, enabled by its workstation-class socket and chiplet design. The Intel processor's dual-channel bus at 102.4 GB/s is typical for a mobile part. The PCIe lane counts, 128 versus 20, further separate the two architectures in terms of expansion capability and I/O throughput. The AMD part's lack of integrated graphics indicates a design that assumes a discrete GPU, while the Intel part's Arc Xe-LPG Graphics 64EU provides built-in display and compute capabilities. These architectural differences explain the benchmark results: the AMD processor's higher thread count, larger L3 cache, and vastly higher memory bandwidth support its dominance in multi-threaded and data-intensive workloads, while the Intel processor's smaller power envelope and integrated graphics make it a different class of product despite its competitive single-thread PassMark result.
