AMD Ryzen Threadripper PRO 9955WX vs Intel Arc G3 EXTREME Comparison

The AMD Ryzen Threadripper PRO 9955WX is the decisive winner in this comparison, taking all 17 head-to-head benchmark matchups against the Intel Arc G3 EXTREME. The data shows a complete performance sweep, with the Threadripper PRO 9955WX delivering massive leads across every workload category, from single-threaded tasks to heavily parallelized rendering.

Head-to-Head Benchmarks

The most dramatic gap appears in Cinebench R23 multicore, where the AMD processor scores 59,494 against the Intel's 14,655, a 306% advantage. This result reflects the fundamental difference between a 16-core desktop workstation processor and a 14-core mobile chip with no multithreading support. The single-core Cinebench R23 result is even more lopsided in percentage terms: the AMD scores 8,399 versus 1,862, giving it a 351.1% lead, which indicates the Zen 5 architecture delivers substantially higher per-thread performance than the Panther Lake mobile part.

Cinebench R15 shows a similar pattern. The Threadripper PRO 9955WX scores 5,996 in multicore versus 2,192, a 173.5% win. In R15 single-core, the AMD leads 846 to 267, a 216.9% margin. The R20 results are nearly identical in both metrics, with the AMD scoring 24,987 multicore and 3,527 single-core against the Intel's 10,945 and 1,545, both delivering a 128.3% advantage.

PassMark integer math is another decisive win for the AMD part, scoring 236,120 versus 71,164, a 231.8% lead. Floating-point math shows a smaller but still clear gap: 156,215 versus 86,929, a 79.7% difference. Data compression favors the AMD by 199.9%, with scores of 920,954 against 307,094. Extended instruction performance is 218% higher on the AMD, scoring 76,363 versus 24,017.

The closest contest is PassMark single-thread performance. The AMD scores 4,530 and the Intel scores 4,293, a margin of only 5.5%. This shows that despite the massive architectural differences in core count and power envelope, the Intel Panther Lake core is reasonably competitive in light single-threaded workloads. However, the AMD still wins this test, and the PassMark multithread score stretches the gap back out: 67,035 versus 30,659, a 118.6% lead.

Data encryption shows an 85.9% advantage for the AMD (44,389 versus 23,881), while random string sorting is 167.4% higher (99,813 versus 37,331). Prime number finding is the narrowest multicore margin, with the AMD at 337 versus 248, a 35.9% lead. Physics performance favors the AMD by 65.2%, scoring 4,156 versus 2,515.

Architecture Differences

The two processors occupy opposite ends of the compute spectrum. The AMD Ryzen Threadripper PRO 9955WX uses the Zen 5 architecture, codenamed Shimada Peak, built on a 4 nm TSMC process. It contains 16 cores and 32 threads, with a base clock of 4.50 GHz and a boost clock of 5.40 GHz. The Intel Arc G3 EXTREME uses the Panther Lake architecture on Intel's 3 nm process, with 14 cores and 14 threads, running at 1.90 GHz base and 4.70 GHz boost. The lack of multithreading on the Intel part halves its thread count relative to core count, while the AMD doubles its cores into 32 threads.

Cache layouts differ substantially. The AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. The Intel part has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The AMD's larger L3 pool is more suited to workstation datasets, while the Intel's per-core L2 is proportionally bigger.

Memory architecture is another major differentiator. The AMD supports DDR5 over an eight-channel memory bus, delivering 409.6 GB/s of bandwidth with ECC support. The Intel uses LPDDR5X over a dual-channel bus, with 136.5 GB/s of bandwidth and no ECC. The AMD has nearly three times the memory bandwidth, which directly supports its multicore throughput results.

PCIe connectivity is also starkly different. The AMD exposes 128 Gen 5 lanes from the CPU, while the Intel provides 4 Gen 5 lanes. The AMD uses socket sTR5 and is an unlocked multiplier part, while the Intel is socketed BGA 2540 with a locked multiplier. The AMD has no integrated graphics, while the Intel includes Arc B390 integrated graphics. The AMD is a desktop market segment part with a 350 TDP, while the Intel is a mobile part with a 25 TDP.

The Verdict

The recorded data supports only one conclusion: the AMD Ryzen Threadripper PRO 9955WX outperforms the Intel Arc G3 EXTREME in every measured benchmark. The AMD wins all 17 head-to-head tests, with leads ranging from 5.5% in PassMark single-thread to 351.1% in Cinebench R23 single-core. The average benchmark score of 101,041 for the AMD versus 36,699 for the Intel places the two parts in different performance classes entirely.

The AMD's nearest rivals are server and workstation processors: the AMD EPYC 7513 (102,244 average score, 1.2% above), the AMD EPYC 8324P (103,329, 2.2% above), the AMD EPYC 4585PX (99,324, 1.7% below), and the AMD Ryzen Threadripper PRO 5965WX (98,504, 2.6% below). This places the 9955WX squarely in the high-end workstation tier.

The Intel Arc G3 EXTREME's nearest rivals are mainstream desktop and mobile processors: the Intel Core Ultra 5 225 (36,938, 0.6% above), the AMD Ryzen 5 5600F (36,945, 0.7% above), the AMD Ryzen 5 5500X3D (37,018, 0.9% above), and the AMD Ryzen AI 7 PRO 450 (37,093, 1.1% above). The Intel part competes with mid-range chips, not with the Threadripper class.

Where Each One Wins

The AMD Ryzen Threadripper PRO 9955WX is the choice for any workload that scales with cores, threads, memory bandwidth, or cache. Its wins span Cinebench R15, R20, and R23 in both single and multicore tests, plus every PassMark workload: data compression, data encryption, extended instructions, prime number finding, floating-point math, integer math, multithread, physics, random string sorting, and single-thread. The 350 TDP, 128 PCIe lanes, eight-channel DDR5 with 409.6 GB/s bandwidth, and 64 MB L3 cache all support sustained heavy compute.

The Intel Arc G3 EXTREME does not win any benchmark in this comparison. Its only near-competitive result is PassMark single-thread, where it trails by 5.5%. Its strengths are in its mobile profile: a 25 TDP, integrated Arc B390 graphics, and a 3 nm Intel process. For applications that require minimal power draw, a compact BGA 2540 platform, and onboard graphics, the Intel part offers those attributes, but the performance data does not show any compute workload where it beats the AMD processor.
