AMD Ryzen Threadripper PRO 9955WX vs Intel Core 7 253PE Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep. The AMD Ryzen Threadripper PRO 9955WX wins all 17 head-to-head benchmark comparisons against the Intel Core 7 253PE. The margins, however, vary dramatically by workload type, and that variation tells the real story.

In Cinebench tests, the AMD processor delivers a remarkably consistent advantage. The Cinebench R15 multicore test shows AMD scoring 5996 against Intel's 2507, a 139.2% delta. Single-core R15 results follow the same pattern: 846 versus 354, a 139% delta. The R20 and R23 tests repeat this near-identical margin, with multicore scores of 24987 versus 10449 and 59494 versus 24880 respectively, both at 139.1% deltas. Single-core R20 and R23 show 139.1% and 139.2% deltas respectively. This consistency across rendering workloads suggests a fundamental throughput advantage rather than a workload-specific quirk.

The PassMark suite reveals where the gap widens and narrows. The largest delta appears in extended instructions, where AMD scores 76363 against Intel's 21806, a massive 250.2% advantage. Random string sorting shows a 204.5% delta (99813 versus 32777), and data compression shows 171.6% (920954 versus 339133). These workloads benefit heavily from the AMD processor's parallel execution resources.

The narrowest margin appears in single-threaded performance. PassMark single-thread shows 4530 versus 3955, a 14.5% delta. This is the only test where Intel comes within striking distance. Floating-point math also shows a relatively smaller gap at 93.2% (156215 versus 80870), while integer math sits at 106.8% (236120 versus 114158). Data encryption shows 141.4% (44389 versus 18385), prime number finding shows 144.2% (337 versus 138), multithread shows 129% (67035 versus 29271), and physics shows 125.3% (4156 versus 1845).

The average benchmark score places AMD at 101041 with a 97th percentile ranking among all CPUs, while Intel sits at 40557 with an 87th percentile ranking. AMD's nearest rivals in the database include the AMD EPYC 7513 with an average score of 102244 (1.2% ahead), the AMD EPYC 8324P at 103329 (2.2% ahead), and the AMD EPYC 4585PX at 99324 (1.7% behind). The Intel Core 7 253PE's nearest rivals include the Intel Core 5 223PE at 40585 (0.1% ahead), the Intel Core Ultra X7 368H at 40518 (0.1% behind), and the Intel Xeon 6357P at 40630 (0.2% ahead). Both processors sit in dense competitive clusters, but at vastly different performance tiers.

Architecture Differences

The AMD Ryzen Threadripper PRO 9955WX uses the Zen 5 architecture with the codename Shimada Peak. The database lists its generation as Ryzen Threadripper (Zen 4 (Storm Peak)), which indicates a generational naming distinction. The Intel Core 7 253PE uses the codename Bartlett Lake and belongs to the Core 7 (Bartlett Lake) generation.

The manufacturing process differs significantly. AMD uses a 4 nm process from TSMC, while Intel uses a 10 nm process from its own foundry. The AMD processor contains 16,630 million transistors across a die size of 2x 70.6 mm². The Intel processor has no transistor count or die size recorded in the database.

Cache hierarchies diverge substantially. AMD provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of L3 cache. Intel provides 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The per-core L1 and L2 allocations favor Intel, but AMD's total L3 cache at 64 MB nearly doubles Intel's 33 MB.

PCIe connectivity shows a stark contrast. AMD offers Gen 5 with 128 lanes (CPU only), while Intel offers Gen 5 with 16 lanes (CPU only). This 112-lane difference positions the AMD processor for multi-GPU and high-density storage configurations, whereas the Intel processor targets more modest expansion needs.

The AMD processor has an unlocked multiplier, while the Intel processor does not. This allows user-controlled frequency adjustment on the AMD side. The AMD processor's part number is 100-000000725, and Intel's is SA4QE.

Where Each One Wins

The AMD Ryzen Threadripper PRO 9955WX wins every recorded benchmark comparison, so the question becomes which workloads benefit most from its advantage. The largest deltas appear in extended instructions (250.2%), random string sorting (204.5%), and data compression (171.6%). These workloads rely heavily on parallel execution, wide vector units, and high memory bandwidth. The eight-channel memory interface at 409.6 GB/s likely drives the sorting and compression results, where data movement dominates.

The AMD processor also excels in rendering and compute-heavy tasks. Cinebench multicore scores show consistent 139% advantages across R15, R20, and R23. Integer math shows a 106.8% delta (236120 versus 114158), and floating-point math shows a 93.2% delta (156215 versus 80870). The 16 cores versus 10 cores, combined with the higher 4.50 GHz base clock, explains much of this gap.

The Intel Core 7 253PE's closest performance comes in single-threaded PassMark testing, where the delta narrows to 14.5%. The Intel processor's 5.50 GHz boost clock exceeds AMD's 5.40 GHz, which helps close the gap in lightly threaded workloads. The Intel processor also offers integrated UHD Graphics 730, which the AMD processor lacks entirely. For systems that require a display output without a discrete GPU, the Intel processor has a functional advantage.

The Intel processor's lower TDP of 65 versus AMD's 350 indicates a substantially lower power envelope, though the database does not record actual power consumption measurements. The dual-channel memory interface and 16 PCIe lanes suggest a more constrained platform for expansion, but also a simpler system design.

The Verdict

The benchmark data supports a clear performance hierarchy. The AMD Ryzen Threadripper PRO 9955WX delivers a 149% higher average benchmark score (101041 versus 40557) and sits at the 97th percentile of all CPUs, while the Intel Core 7 253PE sits at the 87th percentile. In every recorded test, the AMD processor outperforms the Intel processor, with deltas ranging from 14.5% in single-threaded PassMark to 250.2% in extended instructions.

For workloads that demand maximum parallel throughput, rendering capability, data compression, or memory bandwidth, the AMD processor is the only choice between these two. The 16 cores, 32 threads, 64 MB of L3 cache, and eight-channel memory interface at 409.6 GB/s provide the resources that such tasks require. The 128 PCIe Gen 5 lanes support large-scale expansion configurations that the Intel processor's 16 lanes cannot accommodate.

The Intel Core 7 253PE serves a different role. Its 10 cores and 20 threads handle mainstream desktop workloads, and its integrated UHD Graphics 730 provides a complete system solution without a discrete GPU. The 5.50 GHz boost clock helps narrow the single-thread gap, and the 65 TDP suggests a far less demanding power profile. The 33 MB of shared L3 cache and dual-channel memory support indicate a more conventional desktop platform.

The database positions each processor among very different rivals. AMD's nearest competitors are EPYC server processors and a higher-tier Threadripper PRO, all scoring within a narrow 2.6% band. Intel's nearest rivals include the Core 5 223PE, Core Ultra X7 368H, Xeon 6357P, and Ryzen 9 7940H, all within a 0.3% band. Neither processor's closest rivals include the other, which confirms they occupy separate performance tiers despite both being desktop-class parts.

The choice between them depends entirely on workload requirements. The AMD processor wins every measured performance comparison, but the Intel processor offers integrated graphics, a lower power envelope, and a much lower launch MSRP of $384 versus $1649. The data does not support the Intel processor for performance-sensitive tasks, but it does support a role as a lower-power, self-contained desktop processor with strong single-thread boost capability.
