Where Each One Wins

The head-to-head data shows that the AMD Ryzen Threadripper 9970X wins every single benchmark category. There are no benchmark victories for the AMD Ryzen 5 3501U. However, the use-case split is defined by the scale of the Threadripper's wins and the 3501U's inherent design goals.

The Threadripper 9970X delivers overwhelming multi-threaded dominance. In tests that scale with core count, the delta is massive. For example, in data compression, the Threadripper scores 1,757,998 versus the 3501U's 87,380, a delta of 95% in favor of the Threadripper. Similarly, in integer math, the Threadripper scores 465,378 versus 26,321, a 94.3% delta. These results point to workloads like 3D rendering, video encoding, and scientific simulation where the 32-core/64-thread configuration provides a decisive advantage.

The single-thread results offer a different perspective. While the Threadripper still wins, its lead narrows dramatically. In the single-thread test, the Threadripper scores 4,530 compared to the 3501U's 2,136, a delta of 52.8%. This is the closest margin in the entire benchmark suite. For tasks that rely on per-core speed, such as basic office productivity or light web browsing, the 3501U's performance is comparatively much closer to the high-end part, despite its lower absolute scores.

The 3501U's domain is not winning benchmarks but fitting into a specific form factor. Its 15 W TDP, integrated Radeon Vega 8 graphics, and mobile market segment indicate it is designed for extended battery life and compact laptops. The Threadripper 9970X, with a 350 W TDP and no integrated graphics, is a desktop-only component that requires a dedicated GPU and robust cooling. The data confirms the Threadripper is the absolute performance king, while the 3501U serves a completely different, efficiency-focused use case.

Architecture Differences

The two processors are built on fundamentally different architectures that explain their performance gaps. The AMD Ryzen 5 3501U uses the "Picasso" codename, which is part of the Zen+ architecture. The AMD Ryzen Threadripper 9970X uses the "Shimada Peak" codename, built on the Zen 5 architecture.

The process node difference is stark. The 3501U is manufactured on a 12 nm process at GlobalFoundries, while the Threadripper 9970X uses a 4 nm process at TSMC. The smaller node allows for greater transistor density and efficiency. This is reflected in the transistor count: the 3501U has 4,940 million transistors on a 210 mm² die, whereas the Threadripper has 33,260 million transistors distributed across a 4x 70.6 mm² multi-chiplet design.

Cache hierarchies also differ significantly. The 3501U has a small per-core L1 cache of 96 KB and 512 KB of L2 per core, with a shared 4 MB L3 cache. The Threadripper 9970X has 64 KB of L1 per core and a larger 1 MB of L2 per core. Its L3 cache is a massive 128 MB, which is 32 times larger than the 3501U's entire L3 cache. This large cache is critical for feeding the 32 cores with data.

The feature set diverges in other areas. The 3501U includes integrated Radeon Vega 8 graphics, while the Threadripper has no integrated graphics (N/A). The Threadripper is multiplier unlocked, allowing for overclocking, while the 3501U is locked. The memory support also differs: the 3501U uses DDR4, while the Threadripper uses DDR5. The Threadripper supports ECC memory, while the 3501U does not.

Head-to-Head Benchmarks

The database records 11 head-to-head benchmark comparisons. The AMD Ryzen Threadripper 9970X wins all of them. The deltas are consistently large, showcasing the performance chasm between the two parts.

The largest wins for the Threadripper come in compute-heavy tasks. In data compression, the Threadripper scores 1,757,998 against the 3501U's 87,380, a delta of 95%. In floating point math, the scores are 309,719 versus 12,707, a 95.9% delta. The extended instructions test shows a 97.7% delta (142,342 versus 3,274), which is the largest margin in the entire set. These results confirm the Threadripper's dominance in parallel processing and complex calculations.

The multithread benchmark shows a delta of 93.4%, with the Threadripper scoring 107,399 and the 3501U scoring 7,071. The physics test follows a similar pattern, with a 92.9% delta (6,835 versus 483). The data encryption test shows an 86,765 score for the Threadripper versus 5,580 for the 3501U, a 93.6% delta. Random string sorting shows a 191,445 versus 10,414 result, a 94.6% delta.

The narrowest margin is in the single-thread tests. The Threadripper's score of 4,530 is 52.8% higher than the 3501U's 2,136. While this is still a significant lead, it is less than half the delta seen in multi-core tests. This indicates that the Zen 5 architecture and higher clock speeds provide a substantial per-core advantage, but the 3501U's Zen+ cores are not as far behind relative to the massive core-count differences.

The data also places both processors within their respective competitive fields. The 3501U's average score of 14,320 puts it 0.1% behind the AMD Ryzen Embedded V2546 and 1% ahead of the Intel Core i5-10400F. The Threadripper's average score of 279,778 is 0.2% behind the Intel Xeon 6780E and 2.5% behind the AMD EPYC 9555P. These nearest rival comparisons confirm that each processor is positioned near the top of its own performance tier, though the absolute gulf between the mobile and desktop segments is enormous.
