AMD Ryzen Threadripper PRO 9955WX vs Intel Core i9-14901E Comparison

Head-to-Head Benchmarks

The benchmark database shows a completely one-sided contest. The AMD Ryzen Threadripper PRO 9955WX wins all 17 head-to-head comparisons against the Intel Core i9-14901E. The margins, however, vary enormously depending on the workload.

The most dramatic gap appears in PassMark extended instructions, where the AMD part scores 76,363 against Intel's 17,249, a 342.7% advantage. This suggests the Zen 5 implementation carries a substantial throughput advantage for AVX-class and other extended instruction workloads. Data compression follows at 218.9% ahead, with the AMD processor recording 920,954 points versus 288,777. Random string sorting shows a 155% lead, and data encryption is 139% ahead. These are not subtle differences; they indicate fundamentally different execution capacities.

Single-threaded performance is the closest category. In PassMark single-thread, the AMD chip scores 4,530 against 4,354 for the Intel part, a modest 4% lead. This is the only benchmark where the two processors approach parity. The Intel part's higher boost clock of 5.60 GHz against 5.40 GHz does not translate into a win, but it does keep the gap narrow. All other tests show much wider spreads.

Cinebench results are consistently lopsided. In Cinebench R23 multi-core, the AMD processor scores 59,494 versus 25,753, a 131% delta. Single-core R23 shows 8,399 versus 3,635, also a 131.1% delta. The same pattern repeats across R15 and R20. Interestingly, the single-core Cinebench deltas (131.1%) are far larger than the PassMark single-thread delta (4%). The two suites clearly stress different aspects of the processor, and the Cinebench single-core gap suggests a large per-core architectural advantage for Zen 5 in that specific render workload.

PassMark integer math shows the AMD part at 236,120 versus 112,736, a 109.4% lead. Floating point math is 92.6% ahead at 156,215 versus 81,089. Prime number finding, a test sensitive to integer throughput and branch handling, shows a 78.3% gap. PassMark multithread shows a 121.3% lead, while physics simulation is the narrowest PassMark win at 36.7%, with scores of 4,156 and 3,041.

The data indicates the AMD processor does not merely outperform the Intel part; it doubles or triples its throughput in several categories. The only competitive arena is pure single-thread PassMark performance, where the Intel part's high boost clock keeps the gap small.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen Threadripper PRO 9955WX uses the Zen 5 architecture on a 4 nm TSMC process, while the Intel Core i9-14901E uses Raptor Lake on Intel's 10 nm process. The node difference alone explains much of the efficiency and density gap.

Core counts diverge sharply. The AMD part has 16 cores and 32 threads, double the Intel part's 8 cores and 16 threads. This alone accounts for the multi-threaded benchmark gaps. The AMD chip also carries 64 MB of L3 cache, versus 36 MB shared on the Intel part. Per-core cache differs too: 64 KB L1 and 1 MB L2 per core on AMD, versus 80 KB L1 and 2 MB L2 per core on Intel. The Intel part has larger per-core caches, but the AMD part compensates with more cores and a larger total L3.

Memory support is another major differentiator. The AMD processor uses eight-channel DDR5 with a recorded bandwidth of 409.6 GB/s. The Intel part uses dual-channel DDR4 or DDR5, with no bandwidth figure recorded in the database. The eight-channel setup gives the AMD part a massive memory throughput advantage, which likely feeds its strong performance in data compression and encryption tests.

PCIe connectivity also differs. The AMD processor provides Gen 5 with 128 lanes from the CPU, while the Intel part provides Gen 5 with 16 lanes. This positions the AMD chip for multi-GPU and high-bandwidth I/O configurations. The Intel part targets more conventional desktop layouts.

The AMD processor has no integrated graphics, while the Intel part includes UHD Graphics 770. The Intel chip also has a locked multiplier, whereas the AMD chip has an unlocked multiplier. The AMD part uses AMD Socket sTR5, the Intel part uses Intel Socket 1700.

The AMD processor is built from 16,630 million transistors across a 2x 70.6 mm² die configuration. The Intel part has a single 257 mm² die, with no transistor count recorded. The AMD part's dual-die design reflects its chiplet approach, while the Intel part uses a monolithic die.

Release dates differ by about a year. The Intel part entered the database on 2024-06-30, the AMD part on 2025-07-22. The AMD processor carries a launch MSRP of $1649. No launch MSRP is recorded for the Intel part.

Where Each One Wins

The AMD Ryzen Threadripper PRO 9955WX wins every recorded benchmark, so the question is not which processor wins, but how each workload is affected by the size of the margin.

The AMD part dominates in heavily parallel workloads. Cinebench multi-core tests, PassMark multithread, integer math, floating point math, and extended instructions all show leads above 90%. The 16-core, 32-thread configuration, combined with eight-channel memory bandwidth, delivers these results. Data compression and encryption, which are sensitive to both core count and memory bandwidth, show some of the largest gaps.

The Intel Core i9-14901E is closest in PassMark single-thread, trailing by only 4%. This is the only benchmark where the Intel part's 5.60 GHz boost clock meaningfully closes the gap. The Intel part also has the advantage of integrated graphics, which the AMD part lacks entirely. For systems that need a display output without a discrete GPU, the Intel part has a functional edge that no benchmark in this set captures.

The Intel part also holds advantages in platform simplicity. It uses dual-channel memory, which is easier to populate, and its 65 W TDP is far below the AMD part's 350 W. The AMD part's power envelope suggests a need for substantial cooling and power delivery, though the database does not record cooler requirements. The Intel part's lower TDP makes it viable in more modest system builds.

The AMD part's 128 PCIe Gen 5 lanes versus 16 on the Intel part indicates a clear separation in intended use. The AMD processor targets workstation-class configurations with multiple accelerators or storage devices. The Intel part targets conventional desktops where 16 lanes suffice.

The Verdict

The data presents a clear hierarchy. The AMD Ryzen Threadripper PRO 9955WX is in a different performance class from the Intel Core i9-14901E across nearly every recorded metric. Its 17-0 head-to-head record, combined with leads exceeding 100% in most tests, places it firmly in workstation territory. The Intel part, by contrast, sits at the 86th percentile of all CPUs, while the AMD part sits at the 97th percentile.

The AMD part's nearest rivals are server-class EPYC processors, with the AMD EPYC 7513 just 1.2% ahead, the AMD EPYC 8324P 2.2% ahead, and the AMD EPYC 4585PX 1.7% behind. The Ryzen Threadripper PRO 5965WX trails by 2.6%. This places the 9955WX in the same performance envelope as dual-socket server parts.

The Intel Core i9-14901E's nearest rivals are entirely different. The AMD Ryzen AI 9 HX 370 matches it exactly at 0% delta, the AMD Ryzen 7 9700X is 0.1% behind, and the Intel Core 5 211E is 0.2% ahead. This places the Intel part in mainstream desktop territory, competing with mid-range and upper-mid-range chips.

The choice between these two processors depends entirely on the workload and platform requirements. The AMD part delivers roughly 2.3 times the average benchmark score (101,041 versus 37,911) and wins every test, but it demands the sTR5 platform, eight-channel memory, and a 350 W power envelope. The Intel part offers integrated graphics, a 65 W TDP, and a conventional Socket 1700 platform, while trailing by 4% in single-thread PassMark and by massive margins everywhere else.

The recorded data does not support any scenario where the Intel part outperforms the AMD part in raw computation. The Intel part's advantages are platform-level: integrated graphics, lower power, and simpler memory topology. The AMD part's advantages are computational: core count, memory bandwidth, cache, and I/O capacity.
