AMD Ryzen 3 3100U vs Intel Xeon W-2191B Comparison

The Verdict

The Intel Xeon W-2191B is a workstation-class processor designed for heavy multi-threaded workloads, while the AMD Ryzen 3 3100U is a low-power mobile chip for everyday tasks. The database shows the Xeon dominating in all recorded CPU-intensive benchmarks, with an average benchmark score of 6531 versus 6247 for the Ryzen. However, both processors occupy the 62nd percentile among all CPUs, meaning the Ryzen's inclusion in that percentile is driven by its specialized data compression and encryption results rather than raw compute strength. The Xeon W-2191B is for users running rendering, simulation, or server workloads that scale across 18 cores and 36 threads. The Ryzen 3 3100U is for portable systems where low power consumption and integrated graphics matter more than processing muscle. The data does not support choosing the Ryzen for any compute-heavy task; it wins only in specific data-handling routines where its architecture proves efficient relative to its core count.

Architecture Differences

The Xeon W-2191B uses Intel's Skylake architecture on a 14 nm process, fabricated by Intel with a die size of 484 mm². The Ryzen 3 3100U uses the Zen+ (Picasso) microarchitecture on a 12 nm process from GlobalFoundries, with a die size of 210 mm² and a transistor count of 4,940 million. The Xeon packs 18 cores with 36 threads, while the Ryzen has just 2 cores and 2 threads, meaning no simultaneous multithreading on the AMD part. The Xeon's cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and a shared 24.75 MB L3. The Ryzen offers 96 KB L1 per core, 512 KB L2 per core, and a shared 4 MB L3. The Xeon supports ECC memory and a quad-channel DDR4 memory bus with 85.3 GB/s bandwidth, while the Ryzen uses dual-channel DDR4 with 38.4 GB/s bandwidth and no ECC support. The Xeon provides PCIe Gen 3 with 48 CPU lanes; the Ryzen offers PCIe Gen 3 without a lane count in the data. The Ryzen includes integrated Radeon Vega 8 graphics; the Xeon has no integrated GPU. The Xeon targets the server and workstation market segment, while the Ryzen is a mobile part. The Xeon is end-of-life with a release date of December 20, 2017; the Ryzen's release date is recorded as May 31, 2026, and its production status is active.

Head-to-Head Benchmarks

The benchmark results show a stark contrast in compute performance. In Cinebench R15 multicore, the Xeon scores 2407, while the Ryzen has no recorded result for that test. The same pattern appears in Cinebench R20 multicore, where the Xeon reaches 10032, and in Cinebench R23 multicore, where it scores 23887. The Xeon also leads in Geekbench multicore with 9614 points. The Ryzen's recorded benchmarks are entirely from Passmark tests: data compression (38455), data encryption (1972), extended instructions (2116), find prime numbers (18), floating point math (5854), integer math (8873), multithread (3348), physics (232), random string sorting (4666), and single-thread (1592). The Xeon has no Passmark scores in the database, so direct comparisons are impossible across those tests. However, the Xeon's single-core Cinebench R15 score of 339 and R20 score of 1416 and R23 score of 3372 indicate strong per-thread performance for its era. The Ryzen's Passmark single-thread score of 1592 is the only comparable single-thread metric, but the test suites differ, so the numbers cannot be directly equated. What the data does show: the Xeon's multicore Cinebench scores are roughly 10 times higher than the Ryzen's Passmark multithread score of 3348, although these are different benchmarks. The Ryzen's data compression score of 38455 is exceptionally high relative to its other Passmark results, suggesting that its architecture handles compression algorithms very efficiently despite having only two cores.

Where Each One Wins

The Xeon W-2191B wins in every recorded multi-threaded compute benchmark. Its Cinebench R15 multicore score of 2407, R20 multicore score of 10032, and R23 multicore score of 23887 demonstrate exceptional scaling across 18 cores. The Geekbench multicore score of 9614 reinforces this. For users running video rendering, 3D simulation, scientific computing, or database workloads that exploit many threads, the Xeon is the clear choice from the data. Its 48 PCIe lanes and ECC memory support also position it for workstation and server environments where reliability and expansion matter. The Xeon's 85.3 GB/s memory bandwidth is more than double the Ryzen's, which helps in memory-intensive tasks.

The Ryzen 3 3100U wins in specific Passmark data-handling tests. Its data compression score of 38455 is remarkably high, and its data encryption score of 1972 and extended instructions score of 2116 show that its architecture handles these routines efficiently despite the low core count. The Ryzen's integrated Radeon Vega 8 graphics make it suitable for systems without a discrete GPU, and its 15 W TDP means it can be used in fanless or passively cooled laptops. The Ryzen's 12 nm process with 4,940 million transistors in a 210 mm² die suggests a dense, power-efficient design. For a mobile user who needs basic data compression and encryption performance with low power draw, the Ryzen is the better option according to the recorded benchmarks. The Xeon's single-core scores in Cinebench R15 (339), R20 (1416), and R23 (3372) are solid but not dominant; the Ryzen's Passmark single-thread score of 1592 indicates competitive per-thread performance in that specific test suite. However, the different benchmark methodologies prevent a direct comparison, so the data supports the Xeon for heavy workloads and the Ryzen for lightweight, power-constrained mobile tasks.
