AMD Ryzen Threadripper PRO 9955WX vs Intel Core Ultra 5 336H Comparison

Head-to-Head Benchmarks

The benchmark data presents an overwhelmingly one-sided comparison. Across all 17 recorded tests, the AMD Ryzen Threadripper PRO 9955WX claims victory over the Intel Core Ultra 5 336H. The database records zero wins for the Intel part, which makes the analysis straightforward: the Threadripper PRO dominates in every measured category, though the margin varies considerably depending on the workload.

Starting with the Cinebench suite, the AMD processor delivers uniformly consistent performance advantages. In Cinebench R15 multi-core, the Threadripper PRO scores 5996 against 2418 for the Core Ultra 5, a lead of 148%. The single-core R15 test shows the same 148.1% gap, with scores of 846 and 341 respectively. Moving to R20, the multi-core result is 24987 versus 10076 (148% advantage), while single-core shows 3527 against 1422 (148% advantage). The R23 tests follow the identical pattern: 59494 versus 23991 in multi-core and 8399 versus 3387 in single-core, both at exactly 148% delta.

What stands out is the unusual consistency of the Cinebench margins. Every single test, whether R15, R20, or R23, whether single-core or multi-core, lands at precisely 148% (or 148.1% in one case). This uniformity suggests that the AMD chip's architectural advantage scales linearly across rendering workloads, with no test exposing a relative weakness in either core count scaling or clock speed behavior.

The PassMark suite tells a more varied story. The largest margin appears in integer math, where the Threadripper PRO scores 236120 against 62070, a staggering 280.4% advantage. Data compression shows a 228.5% gap (920954 versus 280340), and extended instructions deliver 76363 versus 24542, a 211.2% lead. Random string sorting follows at 190.1% (99813 versus 34402). These four tests reveal that the AMD part's advantage grows substantially in workloads that stress raw arithmetic throughput and memory bandwidth.

Other PassMark tests show narrower but still decisive margins. Floating point math records 156215 versus 82415, a 89.5% advantage. Multi-thread performance sits at 67035 versus 28545, a 134.8% lead. Data encryption shows 44389 against 21291, a 108.5% gap. Physics simulation delivers 4156 versus 2682, a 55% advantage. The closest contest appears in prime number finding, where the AMD chip scores 337 versus 299, a modest 12.7% lead. Single-thread performance also shows a relatively tight race: 4530 versus 4013, a 12.9% gap.

The overall average benchmark score reinforces this picture. The Threadripper PRO 9955WX averages 101041 across all tests, while the Core Ultra 5 336H averages 34485. That places the AMD processor at the 97th percentile among all CPUs in the database, whereas the Intel chip sits at the 84th percentile. The nearest rivals for the AMD part include the AMD EPYC 7513 (average score 102244, delta -1.2%), the AMD EPYC 4585PX (99324, delta 1.7%), the AMD EPYC 8324P (103329, delta -2.2%), and the AMD Ryzen Threadripper PRO 5965WX (98504, delta 2.6%). For the Intel part, the closest competitors are the Intel Core i7-13700HX (34554, delta -0.2%), the Intel Core i5-13450HX (34333, delta 0.4%), the AMD Ryzen 7 3700X (34260, delta 0.7%), and the AMD Ryzen AI 7 350 (34222, delta 0.8%).

Where Each One Wins

Given that the AMD Threadripper PRO 9955WX wins every benchmark in the database, the use-case split is heavily skewed toward the desktop workstation platform. The data shows that the AMD processor excels in every measured category, but the magnitude of the advantage varies meaningfully by workload type.

For integer-heavy tasks, including data compression, random string sorting, and integer math, the Threadripper PRO's lead exceeds 190% in all cases. These workloads benefit from the combination of 16 cores with 32 threads, the large 64 MB L3 cache, and the eight-channel memory bus delivering 409.6 GB/s of bandwidth. The Core Ultra 5 336H, with 16 cores but only 16 threads, dual-channel memory at 115.2 GB/s, and 18 MB of shared L3 cache, cannot keep pace in these data-intensive operations.

For floating-point and physics simulations, the AMD part still leads but by a smaller margin. Floating point math shows an 89.5% advantage, and physics shows 55%. These workloads respond well to raw core count and memory throughput, but the Intel chip's architecture narrows the gap somewhat. The Intel processor's 16 cores without hyperthreading still provide respectable throughput for its mobile segment, yet the Threadripper's superior memory subsystem and higher clock speeds prevail.

For single-threaded tasks, the race tightens considerably. The PassMark single-thread test shows only a 12.9% advantage for AMD (4530 versus 4013), and prime number finding shows a 12.7% lead (337 versus 299). The Threadripper PRO's boost clock of 5.40 GHz versus the Core Ultra 5's 4.60 GHz explains part of this edge, but the Intel part's 3 nm process node and newer Panther Lake architecture keep the gap relatively contained in purely single-threaded scenarios.

The Cinebench family of tests represents a middle ground. All six tests show exactly 148% or 148.1% advantage for AMD, regardless of single-core or multi-core configuration. This suggests that rendering workloads scale proportionally with the Threadripper's core count, thread count, and clock speed advantages, without any architectural bottleneck in either direction.

The Intel Core Ultra 5 336H finds no benchmark category where it claims victory. Its best relative performance comes in single-threaded and prime number workloads, where the gap narrows to around 13%. Its worst relative performance appears in integer math, where it trails by over 280%.

Architecture Differences

The two processors come from fundamentally different market segments and architectural lineages. The AMD Ryzen Threadripper PRO 9955WX belongs to the 9000 series, built on Zen 5 architecture under the codename Shimada Peak. The database lists its generation as Ryzen Threadripper (Zen 4 (Storm Peak)), which suggests a transitional naming situation, but the architecture field clearly identifies Zen 5. This desktop part uses the AMD Socket sTR5 and is manufactured on a 4 nm process at TSMC, with a transistor count of 16,630 million spread across a die size of 2x 70.6 mm².

The Intel Core Ultra 5 336H comes from the Core Ultra Series 3, built on Panther Lake architecture with the same Panther Lake codename. Its generation is listed as Ultra 5 (Panther Lake-H), targeting the mobile segment. Intel manufactures this chip on a 3 nm process at its own foundry. The database does not record transistor count or die size for the Intel part.

Core and thread configurations differ significantly despite both having 16 cores. The AMD processor supports 32 threads through simultaneous multithreading, while the Intel processor runs 16 threads across its 16 cores without hyperthreading. This effectively doubles the AMD part's logical core count, which explains much of the multi-threaded benchmark advantage.

Cache hierarchies follow different philosophies. The AMD chip allocates 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of L3 cache. The Intel processor provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. While the Intel part has larger per-core L1 and L2 allocations, the AMD chip's total L3 capacity of 64 MB dwarfs the Intel's 18 MB shared pool.

Memory support shows stark differences. The AMD processor uses DDR5 with an eight-channel memory bus delivering 409.6 GB/s of bandwidth, and it supports ECC memory. The Intel processor supports both DDR5 and LPDDR5X but with a dual-channel bus providing 115.2 GB/s, and it lacks ECC support. The AMD part's memory bandwidth is roughly 3.5 times higher, which directly feeds its dominance in data-intensive benchmarks.

PCIe connectivity also diverges. The AMD chip provides Gen 5 with 128 lanes from the CPU, while the Intel part offers Gen 5 with only 12 lanes. Integrated graphics differ as well: the AMD processor has none, while the Intel chip includes Intel Xe3 Graphics.

Clock speeds and power envelopes round out the architectural picture. The AMD processor has a base clock of 4.50 GHz and a boost clock of 5.40 GHz, with a TDP of 350 watts. The Intel processor runs at 1.90 GHz base and 4.60 GHz boost, with a TDP of just 25 watts. The Intel chip operates at a fraction of the power draw, but it also runs at significantly lower clocks. The AMD processor has an unlocked multiplier, while the Intel part is locked.

The Verdict

The recorded data leaves no ambiguity about which processor delivers higher performance. The AMD Ryzen Threadripper PRO 9955WX wins all 17 benchmark tests, with advantages ranging from 12.7% in prime number finding to 280.4% in integer math. Its average benchmark score of 101041 nearly triples the Intel part's 34485 average.

The AMD processor belongs in the desktop workstation segment, built for workloads that demand massive memory bandwidth, high core counts with simultaneous multithreading, and extensive PCIe connectivity. Its 16 cores and 32 threads, combined with 64 MB of L3 cache, 128 PCIe Gen 5 lanes, and 409.6 GB/s of memory bandwidth, make it suited for data compression, encryption, extended instruction processing, and multi-threaded rendering. The Cinebench results, all showing exactly 148% advantage over the Intel part, confirm that rendering workloads scale in proportion to the AMD chip's architectural resources.

The Intel Core Ultra 5 336H targets the mobile segment with a 25 watt TDP, integrated Intel Xe3 Graphics, and support for both DDR5 and LPDDR5X memory. Its 16 cores without hyperthreading and 18 MB of shared L3 cache deliver respectable performance for a mobile part, as evidenced by its 84th percentile ranking. Its nearest rivals in the database, including the Intel Core i7-13700HX and AMD Ryzen 7 3700X, all sit within 1% of its average score, indicating that the 336H performs competitively within its own mobile class. However, when compared directly against the Threadripper PRO 9955WX, the performance gap is enormous in every benchmark category.

Choosing between these processors depends entirely on the intended use case. The data shows that the AMD part is the clear choice for desktop workstations requiring maximum computational throughput, particularly in integer-heavy, memory-bandwidth-sensitive, and multi-threaded workloads. The Intel part serves the mobile laptop segment where power efficiency, integrated graphics, and portability take precedence over raw performance. The 350 watt TDP of the AMD processor versus the 25 watt TDP of the Intel processor encapsulates this fundamental difference: one is a high-performance desktop compute engine, the other is an efficient mobile processor.
