The AMD Ryzen Threadripper PRO 9955WX and the Intel Core 5 223PE occupy opposite ends of the desktop processing spectrum. The recorded data shows a complete sweep: the AMD part wins all 17 head-to-head benchmark comparisons, while the Intel part records zero wins. The average benchmark score for the AMD Ryzen Threadripper PRO 9955WX is 101041, placing it in the 97th percentile of all CPUs, while the Intel Core 5 223PE averages 40585, sitting in the 87th percentile. These figures establish a clear performance hierarchy, but the nature of each processor's strengths determines where each fits.

Where Each One Wins

The AMD Ryzen Threadripper PRO 9955WX is the overwhelming choice for heavily threaded workloads. Its 16 cores and 32 threads, combined with a 5.40 GHz boost clock, deliver massive throughput in rendering and content creation. In Cinebench R23 multi-core, the AMD part scores 59494, which is 124.9% ahead of the Intel Core 5 223PE's 26455. The margin extends further in PassMark data compression, where the AMD scores 920954 versus 346623, a 165.7% advantage. For tasks like video encoding, 3D rendering, and scientific simulation, the data consistently favors the AMD processor.

The Intel Core 5 223PE, with 8 cores and 16 threads, still demonstrates respectable capability in single-threaded operations. In PassMark single-thread, the Intel part scores 4219 against the AMD's 4530, a delta of only 7.4%. This narrow gap suggests that in everyday applications with light threading, the Intel processor performs adequately, though it never overtakes the AMD. The Intel chip also features integrated UHD Graphics 730, which the AMD part lacks entirely, making the Intel a functional option for systems without a discrete GPU.

For the AMD Ryzen Threadripper PRO 9955WX, the closest rivals in the database include the AMD EPYC 7513 with an average score of 102244, a 1.2% difference, and the AMD EPYC 8324P at 103329, a 2.2% difference. The AMD Ryzen Threadripper PRO 5965WX trails by 2.6% with an average of 98504. The Intel Core 5 223PE sits near the Intel Core 7 253PE, which scores 40557 (0.1% ahead), and the AMD Ryzen AI 5 PRO 435G at 40718 (0.3% ahead). These rival relationships show that the AMD Threadripper competes in server-class territory, while the Intel Core 5 aligns with mid-range mobile and desktop parts.

Architecture Differences

The two processors diverge fundamentally in their underlying designs. The AMD Ryzen Threadripper PRO 9955WX uses the Zen 5 architecture, codenamed Shimada Peak, built on a 4 nm process by TSMC. The Intel Core 5 223PE uses the Bartlett Lake codename on a 10 nm process from Intel's own foundry. This process difference contributes heavily to the performance and efficiency gap. The AMD chip integrates 16,630 million transistors across a dual-die configuration with each die measuring 70.6 mm², while the Intel part has no recorded transistor count or die size.

Cache structures differ substantially. The AMD Ryzen Threadripper PRO 9955WX allocates 64 KB of L1 cache per core, 1 MB of L2 per core, and a total of 64 MB of L3 cache. The Intel Core 5 223PE provides 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The larger L3 on the AMD part supports more data residency for multi-threaded workloads. Memory support also separates them: the AMD uses DDR5 with an eight-channel memory bus and 409.6 GB/s of bandwidth, while the Intel supports both DDR4 and DDR5 over a dual-channel bus with 89.6 GB/s. Both support ECC memory, but the AMD's bandwidth is nearly four times higher.

PCIe connectivity shows another stark contrast. The AMD Ryzen Threadripper PRO 9955WX provides Gen 5 with 128 lanes from the CPU only, enabling massive expansion for GPUs, storage, and networking. The Intel Core 5 223PE offers Gen 5 with 16 lanes from the CPU only, sufficient for a single graphics card or a couple of NVMe drives. The AMD part also has an unlocked multiplier for overclocking, whereas the Intel multiplier is locked. The AMD uses Socket sTR5, while the Intel uses Socket 1700. The AMD has no integrated graphics, but the Intel includes UHD Graphics 730.

The release dates differ by several months: the AMD arrived on 2025-07-22, and the Intel followed on 2026-03-08. Both are listed as Active in production. The AMD's launch MSRP is $1649, and the Intel's is $232, reflecting their target markets.
