Prime number finding shows 337 versus 68, a 395.6% gap. Physics reaches 4156 versus 868, or 378.8%.

The closest contest is in PassMark single-thread performance, where the AMD part scores 4530 and the Intel part scores 3614, a 25.3% lead. This is the only test where the Core 3 304 comes within a meaningful distance of its rival, though it still loses outright. The Threadripper PRO 9955WX also holds a 97th percentile ranking among all CPUs in the database, while the Core 3 304 sits at the 68th percentile. The average benchmark score for the AMD part is 101041, against 13745 for the Intel part.

Architecture Differences

The two processors occupy entirely different segments of the market, and the architectural data reflects that split. The AMD Ryzen Threadripper PRO 9955WX uses the Zen 5 architecture on the Shimada Peak codename, built on a 4 nm process at TSMC. It packs 16 cores and 32 threads. The Intel Core 3 304 uses the Wildcat Lake codename on Intel's 3 nm process, with 5 cores and 5 threads, meaning no simultaneous multithreading. The generation field lists the AMD part as Ryzen Threadripper (Zen 4 (Storm Peak)) while the Intel part is listed as Core 3 (Wildcat Lake).

Cache configurations differ sharply. The Threadripper PRO 9955WX provides 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3. The Core 3 304 offers 192 KB of L1 total, 2.5 MB of L2 total, and 6 MB of shared L3. The AMD chip also has a transistor count of 16,630 million across a die size of 2x 70.6 mm², while the Intel part lists no transistor or die size data.

Memory support separates the two as well. The AMD processor uses DDR5 with an eight-channel memory bus and 409.6 GB/s of bandwidth, plus ECC support. The Intel chip supports DDR5 and LPDDR5X but only on a single-channel bus, delivering 59.7 GB/s, with no ECC. PCIe connectivity also diverges: the Threadripper PRO 9955WX provides Gen 5 with 128 lanes (CPU only), whereas the Core 3 304 provides Gen 4 with 6 lanes (CPU only). The AMD part has no integrated graphics, while the Intel part includes Intel Xe3 Graphics (1 Xe). Clock speeds show the Threadripper PRO 9955WX at 4.50 GHz base and 5.40 GHz boost, against 1.50 GHz base and 4.30 GHz boost for the Core 3 304. The AMD processor has an unlocked multiplier; the Intel part does not. The AMD chip lists a TDP of 350, the Intel chip 15.

The Verdict

The recorded data gives an unambiguous result. The AMD Ryzen Threadripper PRO 9955WX wins every benchmark in the comparison, with deltas that range from 25.3% to 1030.4%. Its average benchmark score of 101041 is roughly 7.4 times the 13745 average of the Intel Core 3 304. The percentile rankings place the AMD part at 97 and the Intel part at 68, so the Threadripper PRO 9955WX sits near the top of the database while the Core 3 304 lands below most desktop and many mobile processors.

The nearest rivals listed for the AMD part are all server or workstation processors: the AMD EPYC 7513 with an average score of 102244 and a delta of -1.2%, the AMD EPYC 8324P at 103329 with -2.2%, the AMD EPYC 4585PX at 99324 with 1.7%, and the AMD Ryzen Threadripper PRO 5965WX at 98504 with 2.6%. This places the 9955WX in the same performance envelope as dual-socket EPYC parts from previous generations. The Core 3 304, by contrast, sits near the AMD Ryzen Threadripper PRO 3975WX (13786, -0.3%), the Intel Core i7-8750H (13868, -0.9%), the Intel Core 5 120UL (13594, 1.1%), and the AMD EPYC 7443 (13936, -1.4%). Those rivals are a mix of older workstation chips and mobile processors.

The data supports a straightforward conclusion. The Threadripper PRO 9955WX is a high-end desktop processor designed for workloads that scale across 16 cores and 32 threads, with eight-channel memory bandwidth and 128 PCIe Gen 5 lanes. The Core 3 304 is a mobile processor with 5 cores, single-channel memory, and integrated graphics, aimed at low-power systems. Their benchmark scores reflect that positioning, but the size of the gap, particularly in multi-core and memory-heavy tests, goes beyond simple segment differences. The AMD part is not merely faster; it is faster by an order of magnitude in several tests.

Where Each One Wins

The AMD Ryzen Threadripper PRO 9955WX wins all 17 recorded benchmarks, so the "where each one wins" split is lopsided. Still, the data reveals which workloads show the most extreme separation and where the Intel part comes closest to closing the gap.

The Threadripper PRO 9955WX shows its greatest dominance in heavily parallel workloads. Cinebench R23 multi-core at 1030.4% ahead, integer math at 858.3%, data compression at 702.4%, and extended instructions at 688.4% all point to scaling across the 16 cores and 32 threads. The eight-channel memory bus and 409.6 GB/s of bandwidth support these results, as does the 64 MB L3 cache. The PassMark multi-thread score of 67035 against 11625 (476.6%) confirms that the AMD part sustains its advantage in mixed parallel work.

The closest contest appears in PassMark single-thread, where the Threadripper PRO 9955WX leads by only 25.3%. The Intel Core 3 304 boosts to 4.30 GHz on a 3 nm process, and its single-thread score of 3614 shows that it is not entirely outclassed in lightly threaded tasks. The Cinebench R15 single-core test shows a wider gap of 220.5% (846 versus 264), which suggests the Intel part's single-thread standing is inconsistent across tests. The Core 3 304 also delivers integrated Intel Xe3 Graphics, which the AMD part lacks entirely, so for systems requiring a built-in display output, the Intel chip has a functional advantage that benchmarks do not capture.

The Intel part also wins on power characteristics. Its TDP of 15 stands against 350 for the AMD chip, and it uses a single-channel memory bus and 6 PCIe Gen 4 lanes, all consistent with a low-power mobile design. The AMD part, by contrast, requires a desktop platform with AMD Socket sTR5, 128 PCIe Gen 5 lanes, and eight-channel memory. The data shows that the Threadripper PRO 9955WX is the clear performance leader in every measured category, while the Core 3 304 offers a compact, low-power alternative with integrated graphics and a much smaller physical and electrical footprint.

Specification Differences

The two processors differ in nearly every specification field. The AMD Ryzen Threadripper PRO 9955WX uses 16 cores and 32 threads, while the Intel Core 3 304 uses 5 cores and 5 threads.
