AMD Ryzen 3 3100U vs AMD Ryzen Threadripper 1950X Comparison

AMD's Ryzen 3 3100U and Ryzen Threadripper 1950X occupy opposite ends of the company's product stack, yet their aggregate benchmark scores are remarkably close. The 3100U is a 15-watt mobile processor with two cores and integrated graphics, while the Threadripper 1950X is a 180-watt desktop monster with 16 cores and 32 threads. The data shows both chips land at the 62nd percentile of all CPUs, with the 3100U posting an average score of 6247 against the Threadripper's 6231—a difference of just 0.3%. This head-to-head is less about raw capability and more about workload fit, as the two parts deliver their scores through wildly different architectures.

The Verdict

The Ryzen 3 3100U is the clear pick for anyone whose workload is dominated by single-threaded tasks or light, everyday computing. Its 1.59x higher single-thread score over the Threadripper in PassMark's single-thread test (1592 vs 1183 in Geekbench single-core) shows that its higher clock efficiency and newer 12nm Picasso design translate to snappier response in typical applications. The 3100U also wins decisively in data compression (38455 vs the Threadripper's lack of a comparable score in that specific test), making it a sensible choice for budget laptops or compact systems where power draw is a concern.

The Ryzen Threadripper 1950X, however, is the only rational choice for multi-threaded, content-creation, or rendering workloads. Its 16 cores and 32 threads deliver a 23440 score in Cinebench R23 multi-core, which is the kind of number that only a high-core-count part can produce. The data shows it crushes the 3100U in every multi-threaded benchmark listed, from Cinebench R15 multi-core (2362) to Geekbench multi-core (7989). If your workflow is video encoding, 3D rendering, or software compilation, the Threadripper is the only one of the two that will keep up.

Benchmark results indicate that the 3100U is a better fit for mobile users who need battery life and portability, while the Threadripper 1950X is for desktop users who prioritize throughput over everything else. The near-identical average scores (6247 vs 6231) are misleading; they mask the fact that these chips are optimized for entirely different use cases. Pick the 3100U for single-threaded or light tasks, and the Threadripper 1950X for heavy parallel workloads.

Architecture Differences

The two processors come from different generations and are built on different process nodes. The Ryzen 3 3100U uses the Picasso architecture, based on the Zen+ generation, and is fabricated on a 12nm process at GlobalFoundries. The Threadripper 1950X uses the original Zen architecture (codenamed Whitehaven) and is built on a 14nm process, also at GlobalFoundries. This node difference is significant: the 12nm process allows the 3100U to be more power-efficient, which is why it can run at just 15W TDP while the Threadripper requires 180W.

The core counts are drastically different. The 3100U has 2 cores and 2 threads, while the Threadripper 1950X has 16 cores and 32 threads—an 8x difference in cores and a 16x difference in threads. This is the single most important architectural distinction, as it dictates where each chip excels. The Threadripper's massive core count is supported by a much larger L3 cache: 32 MB total versus 4 MB shared on the 3100U. Both have 96 KB of L1 cache per core and 512 KB of L2 cache per core.

Memory architecture also diverges. The 3100U supports dual-channel DDR4 with a memory bandwidth of 38.4 GB/s, while the Threadripper 1950X supports quad-channel DDR4 with a bandwidth of 85.3 GB/s. The Threadripper's memory bandwidth is more than double, which is critical for feeding its many cores. The 3100U has integrated Radeon Vega 8 graphics, while the Threadripper has no integrated graphics—it requires a discrete GPU. The 3100U is a mobile part on AMD Socket FP5, whereas the Threadripper is a desktop part on AMD Socket SP3r2.

The Threadripper 1950X is multiplier-unlocked, meaning it can be overclocked, while the 3100U is locked. The Threadripper also has a higher base clock (3.40 GHz vs 1.90 GHz) and a higher boost clock (4.00 GHz vs 3.20 GHz), which helps it in single-threaded scenarios despite its older architecture.

FAQ

Q: Which chip has better single-threaded performance?

A: The Ryzen 3 3100U. It scores 1592 in PassMark single-thread, while the Threadripper 1950X scores 1183 in Geekbench single-core. The 3100U's higher boost clock of 3.20 GHz and newer 12nm node give it an edge in lightly threaded tasks.

Q: How much faster is the Threadripper 1950X in multi-threaded workloads?

A: The Threadripper 1950X scores 23440 in Cinebench R23 multi-core and 7989 in Geekbench multi-core. The 3100U's multi-thread score is 3348 in PassMark, which is a fraction of the Threadripper's output. The 16-core/32-thread design is overwhelmingly faster for parallel tasks.

Q: Do both chips support the same memory?

A: Both support DDR4 memory, but the implementation differs. The 3100U uses dual-channel memory with 38.4 GB/s bandwidth, while the Threadripper 1950X uses quad-channel memory with 85.3 GB/s bandwidth. Neither supports ECC memory.

Q: Which processor is better for a laptop?

A: The Ryzen 3 3100U is the only mobile option. It has a 15W TDP, is on AMD Socket FP5, and includes integrated Radeon Vega 8 graphics. The Threadripper 1950X is a desktop part with a 180W TDP and no integrated graphics.

Q: Are these processors still in production?

Head-to-Head Benchmarks

The 3100U's biggest win comes in PassMark data compression, where it scores 38455. The Threadripper 1950X has no comparable score in that test, so the comparison is one-sided. In single-threaded performance, the 3100U scores 1592 in PassMark single-thread, which outpaces the Threadripper's Geekbench single-core score of 1183. This represents a meaningful advantage for the mobile chip in everyday tasks like web browsing or document editing.

The Threadripper 1950X dominates every multi-threaded benchmark. In Cinebench R23 multi-core, it scores 23440, which is a massive figure that reflects its 16 cores and 32 threads. Its Cinebench R20 multi-core score is 9844, and its Cinebench R15 multi-core score is 2362. In Geekbench multi-core, it scores 7989. The 3100U's PassMark multi-thread score is 3348, which is less than half of the Threadripper's Cinebench R15 multi-core score alone.

The Threadripper also wins in single-core Cinebench tests, scoring 3309 in Cinebench R23 single-core and 1389 in Cinebench R20 single-core. This suggests that even in single-threaded rendering tasks, the Threadripper's higher base clock of 3.40 GHz and boost clock of 4.00 GHz help it outperform the 3100U, despite the latter's newer architecture.

In the aggregate, the two chips are nearly tied: the 3100U has an average benchmark score of 6247, while the Threadripper 1950X sits at 6231, a 0.3% difference. The nearest rivals list confirms this equilibrium, with the 3100U being 0.3% ahead of the Threadripper, and the Threadripper being 0.3% behind the 3100U. Other rivals like the AMD EPYC 7272 (6186) and Intel Core i9-7940X (6147) fall within a 1.7% band, showing that both AMD parts sit at a similar performance tier in aggregate metrics. However, the distribution of that performance could not be more different—one is a low-power mobile chip, the other a high-core-count desktop processor.
