Architecture Differences

The AMD Ryzen 3 3100U belongs to the 3000 series and uses the Picasso codename, based on Zen+ architecture. It is manufactured by GlobalFoundries on a 12 nm process. The processor integrates Radeon Vega 8 graphics and targets the mobile market segment via AMD Socket FP5. Its transistor count is recorded at 4,940 million on a 210 mm² die.

The Intel Core i9-14901KE is part of the Core 14th Gen series, uses the Raptor Lake architecture with the Raptor Lake-R codename, and is built on a 10 nm process by Intel. The die size is 257 mm², with no transistor count recorded. It integrates UHD Graphics 770 and targets the desktop market segment via Intel Socket 1700. The architecture is Raptor Lake Refresh, a later generation than Zen+.

Cache hierarchy differs substantially. The AMD part uses 96 KB L1 per core, 512 KB L2 per core, and 4 MB shared L3. The Intel part uses 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. The Intel L2 is 4x larger per core, and the L3 is 9x larger overall.

Memory architecture diverges: the AMD part supports DDR4 only with dual-channel memory and a recorded bandwidth of 38.4 GB/s. The Intel part supports both DDR4 and DDR5 with dual-channel memory, but its bandwidth is not recorded. ECC memory is supported only on the Intel part.

PCIe capability differs by two generations: AMD offers Gen 3, while Intel offers Gen 5 with 16 lanes (CPU only). The Intel part also has an unlocked multiplier, while the AMD part is locked.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two processors. The winsA and winsB fields are both 0. The Intel Core i9-14901KE has an empty benchmarks array and an average benchmark score of 0. The AMD Ryzen 3 3100U has 11 recorded benchmark scores with an average of 6247.

For the AMD Ryzen 3 3100U, the recorded scores show its strongest area is passmark_data_compression at 38455. The next highest is passmark_integer_math at 8873. Floating point math scores 5854. Random string sorting scores 4666. Multithread scores 3348. Extended instructions score 2116. Data encryption scores 1972. Single-thread scores 1592. Physics scores 232. Find prime numbers scores 18.

The Intel part has no recorded benchmark scores, so no direct comparison of measured performance is possible from the database. The AMD part’s nearest rivals include the AMD Ryzen Threadripper 1950X with an average score of 6231 (0.3% below the 3100U), the AMD EPYC 7272 at 6186 (1% below), the Intel Core i9-10920X at 6347 (1.6% above), and the Intel Core i9-7940X at 6147 (1.6% below). These rivals are all high-core-count desktop or server processors, yet the 3100U’s average score sits within 1.6% of them.

The AMD Ryzen 3 3100U holds a 62nd percentile ranking among all CPUs. The Intel Core i9-14901KE holds a 50th percentile ranking. However, the Intel part’s percentile is based on no recorded benchmarks, so its ranking reflects unmeasured data. The AMD part’s percentile is supported by its 11 recorded tests.

The Verdict

The data presents an unusual pairing: a low-power mobile chip with full benchmark coverage against a high-end desktop chip with no recorded measurements. The AMD Ryzen 3 3100U is the only processor with verifiable benchmark results. Its average score of 6247 places it in the 62nd percentile, and it trades within 1.6% of four rival desktop and server processors with far more cores.

The Intel Core i9-14901KE cannot be benchmarked from the recorded data. Its average score is 0, and its 50th percentile ranking is unsupported by any measurements. The specification sheet, however, shows massive advantages: 8 cores versus 2, 16 threads versus 2, a 5.80 GHz boost clock versus 3.20 GHz, 36 MB L3 versus 4 MB, and support for DDR5 and ECC memory.

For system builders prioritizing measured, verified performance in the database, the AMD Ryzen 3 3100U is the only option with recorded scores. Its mobile segment, 15 W TDP, and lower clocks suit low-power or compact systems. For anyone prioritizing raw specification headroom, the Intel Core i9-14901KE offers 4x the cores, 8x the threads, a 9x larger L3 cache, and a newer PCIe generation, but none of that performance is quantified in the database.

The AMD part’s 62nd percentile ranking, supported by 11 tests, contrasts with the Intel part’s 50th percentile ranking with zero tests. The recorded data confirms the 3100U as a functional, measurable processor. The Intel i9-14901KE remains an unverified entry whose capabilities are documented only through specifications, not through benchmark results.
