AMD Ryzen 3 3100U vs Intel Core 7 251E Comparison

AMD Ryzen 3 3100U vs Intel Core 7 251E

The AMD Ryzen 3 3100U and the Intel Core 7 251E occupy different segments of the processor market, and the recorded data shows a clear separation in their intended roles. The Ryzen 3 3100U is a mobile-focused, low-power chip, while the Core 7 251E is a desktop-oriented, high-core-count part. The benchmark database contains no direct head-to-head measurements between these two processors, and the Intel Core 7 251E has no recorded benchmark scores of its own. The analysis below relies on the available specification data and the Ryzen 3 3100U's own benchmark results to outline what each processor offers.

Head-to-Head Benchmarks

The database does not list any direct head-to-head benchmark results for the AMD Ryzen 3 3100U versus the Intel Core 7 251E. The Ryzen 3 3100U has a complete set of PassMark scores, while the Core 7 251E has no recorded benchmark entries. Therefore, a direct comparison of measured performance is not possible from the available data.

The Ryzen 3 3100U's own benchmark results provide a reference point for its capabilities. In single-threaded tests, it scores 1592 in both passmark_single_thread and passmark_singlethread. Its multithreaded score is 3348. The floating point math test yields 5854, and integer math reaches 8873. Data compression scores 38455, while data encryption is notably lower at 1972. Extended instructions score 2116, and finding prime numbers returns just 18. Random string sorting produces 4666, and the physics test records 232.

The Ryzen 3 3100U holds a 62nd percentile ranking among all CPUs in the database, with an average benchmark score of 6247. Its nearest rivals in the database are all significantly higher-end desktop processors. The AMD Ryzen Threadripper 1950X scores 6231, a 0.3% delta from the Ryzen 3 3100U's average. The AMD EPYC 7272 scores 6186, a 1% delta. The Intel Core i9-10920X scores 6347, a -1.6% delta, meaning the Ryzen 3 3100U trails that chip by 1.6%. The Intel Core i9-7940X scores 6147, a 1.6% delta, meaning the Ryzen 3 3100U leads that processor by 1.6% in average score. These rival deltas indicate that the Ryzen 3 3100U's average benchmark score places it in the same performance vicinity as these much larger desktop parts, despite having only 2 cores and 2 threads.

The Intel Core 7 251E has no benchmark data in the database, and its average benchmark score is listed as 0. Its percentile ranking is 50, which is below the Ryzen 3 3100U's 62nd percentile. However, without any recorded test scores for the Core 7 251E, no performance comparison can be drawn from measured results. The database shows zero wins for either processor in head-to-head benchmarks, confirming the absence of direct test comparisons.

The Verdict

The data does not support a direct performance verdict because the Intel Core 7 251E has no recorded benchmark scores. The Ryzen 3 3100U has a full set of scores and a 62nd percentile ranking, while the Core 7 251E sits at the 50th percentile with an average score of 0. The Ryzen 3 3100U's average benchmark score of 6247 places it near much larger desktop processors in the database, but this does not translate to a comparison with the Core 7 251E.

From a specification standpoint, the two processors target different use cases. The Ryzen 3 3100U is a mobile processor with a 15-watt TDP, 2 cores, and 2 threads. The Core 7 251E is a desktop processor with a 65-watt TDP, 24 cores, and 32 threads. The Core 7 251E has a higher base clock (2.10 GHz versus 1.90 GHz) and a significantly higher boost clock (5.60 GHz versus 3.20 GHz). The Core 7 251E also supports ECC memory, which the Ryzen 3 3100U does not. The Ryzen 3 3100U's launch MSRP is not listed, while the Core 7 251E has a launch MSRP of $384.

For users seeking a low-power mobile chip with a recorded benchmark presence, the Ryzen 3 3100U is the only option with measured data. For users requiring a high-core-count desktop processor with ECC memory support and a higher boost clock, the Core 7 251E offers those specifications, but its performance remains unmeasured in the database.
