AMD Ryzen Threadripper PRO 9955WX vs Intel Core i7-14701E Comparison

Where Each One Wins

The benchmark data presents an unambiguous split between these two processors. The AMD Ryzen Threadripper PRO 9955WX wins all 17 recorded head-to-head comparisons, while the Intel Core i7-14701E does not secure a single victory. This is not a close contest by any measure.

The Threadripper PRO 9955WX dominates in every multi-threaded workload category. In Cinebench R23 multicore, it scores 59,494 against the Intel chip's 22,195, a 168.1% advantage. The gap widens further in PassMark data compression, where the AMD part records 920,954 versus 282,939, a 225.5% lead. Extended instruction workloads show the largest disparity at 312.1%, with scores of 76,363 and 18,528 respectively.

Single-thread performance tells a different story. The AMD processor still wins, but the margin shrinks dramatically. In PassMark single-thread, the Threadripper PRO 9955WX scores 4,530 against 4,305 for the Core i7-14701E, a modest 5.2% advantage. This indicates that while the AMD part has superior per-core capability, the gap is nowhere near as large as in multi-threaded scenarios.

The use-case split is therefore clear. The Threadripper PRO 9955WX is built for heavily parallel workloads: rendering, scientific computing, data compression, and encryption tasks that can exploit its 16 cores and 32 threads. The Core i7-14701E, with 8 cores and 16 threads, targets more conventional desktop workloads where single-thread responsiveness matters most, though even there it trails.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Threadripper PRO 9955WX uses the Zen 5 architecture, codenamed Shimada Peak, built on a 4 nm process at TSMC. It belongs to the 9000 series and the Ryzen Threadripper generation, with a dual-die design measuring 2x 70.6 mm² and containing 16,630 million transistors. The Intel Core i7-14701E uses Raptor Lake architecture, codenamed Raptor Lake-R, on a 10 nm process at Intel, with a monolithic die of 257 mm².

Core counts differ substantially. The AMD part offers 16 cores and 32 threads, while the Intel part provides 8 cores and 16 threads. Base clocks are 4.50 GHz for the Threadripper and 2.60 GHz for the Core i7, though both boost to 5.40 GHz. Thermal design power is another major divider: 350 W for the AMD processor versus 65 W for the Intel chip.

Cache hierarchies reflect the different target markets. The Threadripper PRO 9955WX has 64 KB L1 per core, 1 MB L2 per core, and 64 MB of shared L3 cache. The Core i7-14701E has 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. The larger L3 on the AMD part supports its multi-threaded workload focus.

Memory architecture reinforces this divergence. The Threadripper PRO 9955WX supports DDR5 with an eight-channel memory bus and 409.6 GB/s bandwidth. The Core i7-14701E supports both DDR4 and DDR5 but only on a dual-channel bus, with no bandwidth figure recorded. Both support ECC memory, which suits professional workstation environments.

PCIe connectivity also differs sharply. The AMD processor provides Gen 5 with 128 lanes, while the Intel part offers Gen 5 with 16 lanes. This positions the Threadripper for multi-GPU and high-bandwidth storage configurations, whereas the Core i7 targets more modest expansion needs.

The Threadripper PRO 9955WX has no integrated graphics, while the Core i7-14701E includes UHD Graphics 770. The AMD processor is multiplier-unlocked, the Intel chip is not. Release dates are recorded as 2025-07-22 for the AMD part and 2024-06-30 for the Intel part.

The Verdict

The recorded data supports a straightforward conclusion. The AMD Ryzen Threadripper PRO 9955WX is the superior processor in every benchmark category measured. Its 17 wins out of 17 comparisons, combined with an average benchmark score of 101,041 against 33,206 for the Intel part, leaves no ambiguity.

The percentile rankings place the AMD processor at 97 versus 83 for the Intel chip. The nearest rivals for the Threadripper PRO 9955WX are all server or workstation-class parts: the AMD EPYC 7513 at 102,244 average score (1.2% higher), the AMD EPYC 4585PX at 99,324 (1.7% lower), the AMD EPYC 8324P at 103,329 (2.2% higher), and the AMD Ryzen Threadripper PRO 5965WX at 98,504 (2.6% lower). This places the 9955WX firmly in enterprise territory.

The Core i7-14701E sits in a completely different competitive space. Its nearest rivals are mobile and desktop parts: AMD Ryzen 9 PRO 6950H at 33,201 (0% delta), AMD Ryzen 5 8645HS at 33,244 (0.1% lower), AMD Ryzen 7 7745HX at 33,091 (0.3% higher), and Intel Core i7-13650HX at 33,089 (0.4% higher). The 14701E is a mainstream desktop processor, not a workstation part.

Who should pick which depends entirely on workload requirements. The Threadripper PRO 9955WX is for systems that need massive parallel throughput, extensive memory bandwidth, and high lane-count PCIe expansion. The Core i7-14701E suits conventional desktop builds where the 65 W TDP and integrated graphics reduce system complexity, though it sacrifices performance in every measured category.

Head-to-Head Benchmarks

The largest victory for the AMD processor comes in PassMark extended instructions, where it scores 76,363 against 18,528. The 312.1% delta represents the most extreme performance difference in the entire comparison. This workload typically exercises SIMD and cryptography instruction sets, areas where the Zen 5 architecture with its larger core count and newer process node has a decisive edge.

PassMark data compression shows a 225.5% lead. The Threadripper PRO 9955WX records 920,954, while the Core i7-14701E manages 282,939. This workload scales strongly with core count and memory bandwidth, both of which favor the AMD part. Random string sorting follows at 242.3% (99,813 versus 29,158), another memory-intensive operation.

Data encryption delivers a 198.7% advantage. The AMD processor scores 44,389 against 14,862. Integer math shows a 190.3% gap at 236,120 versus 81,325. These workloads benefit from the Threadripper's 16 cores and eight-channel memory subsystem.

The Cinebench suite shows consistent 168% leads across all four tests. R15 multicore: 5,996 versus 2,237, a 168% delta. R15 single-core: 846 versus 315, a 168.6% delta. R20 multicore: 24,987 versus 9,321, a 168.1% delta. R20 single-core: 3,527 versus 1,315, a 168.2% delta. R23 multicore: 59,494 versus 22,195, a 168.1% delta. R23 single-core: 8,399 versus 3,133, a 168.1% delta. These consistent margins across rendering workloads indicate a uniform architectural advantage rather than workload-specific behavior.

PassMark multithread shows a 156.7% lead at 67,035 versus 26,112. Floating-point math delivers a 152.5% advantage at 156,215 versus 61,873. Physics simulation shows a 73.2% lead at 4,156 versus 2,399. Prime number finding has the smallest multi-threaded margin at 91.5% (337 versus 176), which still represents a substantial gap.

The narrowest win for the AMD processor is in PassMark single-thread at 5.2% (4,530 versus 4,305). This is the only benchmark where the two processors are competitive. It suggests that per-core IPC is relatively close between Zen 5 and Raptor Lake, with the Threadripper's higher base clock of 4.50 GHz versus 2.60 GHz contributing to its advantage. Both parts boost to 5.40 GHz, but the higher sustained base clock on the AMD part likely helps in shorter single-thread bursts.

Across all 17 recorded comparisons, the AMD Ryzen Threadripper PRO 9955WX wins every test. The average benchmark score of 101,041 for the AMD part versus 33,206 for the Intel part reflects a 204.3% overall difference. The percentile placement of 97 versus 83 confirms that these processors occupy different tiers entirely. The data shows no scenario where the Core i7-14701E provides better measured performance.
