AMD Ryzen 3 3100U vs Intel Core 7 253PQE Comparison

Architecture Differences

The AMD Ryzen 3 3100U and Intel Core 7 253PQE occupy opposite ends of the processor spectrum, and the architectural gap between them explains nearly every benchmark result in the database. The AMD part is a 2-core, 2-thread mobile processor built on the Zen+ (Picasso) architecture, manufactured on a 12 nm process at GlobalFoundries. It uses AMD Socket FP5, integrates Radeon Vega 8 graphics, and belongs to the 3000 series. The Intel part is a 10-core, 20-thread desktop processor based on the Bartlett Lake architecture, built on a 10 nm process at Intel, and uses Intel Socket 1700 with UHD Graphics 770.

The transistor and die data underline how different these designs are. The Ryzen 3 3100U contains 4,940 million transistors on a 210 mm² die. The Intel Core 7 253PQE has no transistor count or die size recorded in the database, but its cache hierarchy reveals a much larger physical design. The AMD chip provides 96 KB of L1 cache per core and 512 KB of L2 per core, with 4 MB of shared L3 cache. The Intel chip provides 80 KB of L1 per core and 2 MB of L2 per core, with 33 MB of shared L3 cache. That L3 difference, 4 MB versus 33 MB, is one of the largest structural disparities between the two.

Memory support also diverges sharply. The Ryzen 3 3100U supports DDR4 only, on a dual-channel bus with a recorded memory bandwidth of 38.4 GB/s. The Intel Core 7 253PQE supports both DDR4 and DDR5, also on a dual-channel bus, but with a recorded memory bandwidth of 89.6 GB/s. ECC memory is not supported on the AMD part, while the Intel part lists ECC support as enabled. PCIe connectivity differs as well: the AMD processor runs PCIe Gen 3, while the Intel processor runs PCIe Gen 5 with 16 lanes available on the CPU only.

The clock speeds tell a similar story. The AMD Ryzen 3 3100U has a base clock of 1.90 GHz and a boost clock of 3.20 GHz. The Intel Core 7 253PQE starts at 3.50 GHz base and reaches 5.70 GHz boost. The Intel part also carries a 125 W TDP versus the AMD part's 15 W TDP, which reflects the desktop versus mobile design intent. Neither processor has an unlocked multiplier. The release dates in the database show the Intel part appearing earlier in 2026, with the AMD part dated later in the same year.

The Verdict

The benchmark data is unambiguous. The Intel Core 7 253PQE wins all 11 recorded head-to-head benchmark comparisons, with no wins recorded for the AMD Ryzen 3 3100U. The average benchmark score for the Intel part is 55,919, while the AMD part averages 6,247. The Intel processor sits at the 91st percentile of all CPUs in the database, while the AMD processor sits at the 62nd percentile.

The Intel part's nearest rivals in the database are all high-end desktop and mobile parts: the Intel Core i9-14900HX (average score 56,004, a 0.2% difference), the AMD Ryzen AI Max 390 (56,273, 0.6% difference), the AMD Ryzen AI 9 HX PRO 470 (56,306, 0.7% difference), and the AMD Ryzen Threadripper PRO 3955WX (56,555, 1.1% difference). This places the Core 7 253PQE firmly in flagship territory. The AMD Ryzen 3 3100U, by contrast, sits near the AMD Ryzen Threadripper 1950X (6,231, 0.3% difference), the AMD EPYC 7272 (6,186, 1% difference), the Intel Core i9-10920X (6,347, a 1.6% difference the other way), and the Intel Core i9-7940X (6,147, 1.6% difference). These are older or lower-tier parts, and the Ryzen 3 3100U is competitive with them only in aggregate score.

From the data, the Intel Core 7 253PQE is the choice for any workload that benefits from high core counts, high clock speeds, large cache, or fast memory bandwidth. The AMD Ryzen 3 3100U is a low-power mobile part whose 15 W TDP and integrated Vega graphics target lightweight, power-constrained systems. The database shows no benchmark category where the AMD part leads, so the selection is driven entirely by platform and power requirements rather than performance.

Head-to-Head Benchmarks

The head-to-head benchmark data shows a consistent pattern across every test category. The Intel Core 7 253PQE leads in all 11 comparisons, with the largest deltas appearing in compute-heavy workloads and the smallest in single-thread performance.

The floating point math test shows the widest gap. The AMD Ryzen 3 3100U scores 5,854, while the Intel Core 7 253PQE scores 105,279, a 94.4% difference in favor of the Intel part. Integer math follows closely: 8,873 versus 137,795, a 93.6% difference. Extended instructions show a 93.5% gap, with scores of 2,116 and 32,390. Data encryption shows a 92.3% difference, with 1,972 versus 25,515. The physics test shows a 92.2% difference, with 232 versus 2,970. The multithread test shows a 92% difference, with 3,348 versus 41,656. Data compression shows a 92.1% difference, with 38,455 versus 487,335. Random string sorting shows a 91.4% difference, with 4,666 versus 54,222. Prime number finding shows a 91.3% difference, with 18 versus 206.

The single-thread tests show the smallest relative gap, but it is still substantial. The AMD part scores 1,592 in both passmark single-thread and passmark singlethread tests, while the Intel part scores 4,389 in both, a 63.7% difference. This indicates that even in a workload that does not scale with core count, the Intel architecture holds a commanding lead.

The Intel part's Cinebench results add context for its multi-core capability. In Cinebench R15, it scores 3,163 multi-core and 446 single-core. In Cinebench R20, it scores 13,183 multi-core and 1,861 single-core. In Cinebench R23, it scores 31,390 multi-core and 4,431 single-core. The AMD part has no Cinebench results recorded in the database, so direct comparison in that suite is not possible, but the Passmark data alone shows a decisive margin.

Specification Differences

Base clocks are 1.90 GHz versus 3.50 GHz, and boost clocks are 3.20 GHz versus 5.70 GHz. The TDP is 15 W versus 125 W. The AMD part uses AMD Socket FP5, while the Intel part uses Intel Socket 1700. The AMD part is built on a 12 nm process at GlobalFoundries, while the Intel part uses a 10 nm process at Intel. The AMD codename is Picasso, while the Intel codename is Bartlett Lake.

Cache configurations differ at every level. The AMD part has 96 KB of L1 per core and 512 KB of L2 per core, with 4 MB of shared L3. The Intel part has 80 KB of L1 per core and 2 MB of L2 per core, with 33 MB of shared L3. Memory support is DDR4 only on the AMD side, versus DDR4 and DDR5 on the Intel side. Memory bandwidth is 38.4 GB/s versus 89.6 GB/s. ECC memory is absent on the AMD part and present on the Intel part. PCIe generation is Gen 3 on the AMD part versus Gen 5 with 16 CPU lanes on the Intel part. Integrated graphics differ as well: Radeon Vega 8 on the AMD part, UHD Graphics 770 on the Intel part.

The market segment and release dates also differ. The AMD part is a mobile processor with a release date of 2026-05-31, while the Intel part is a desktop processor with a release date of 2026-03-08.

Where Each One Wins

The database records zero benchmark wins for the AMD Ryzen 3 3100U across all 11 head-to-head tests. The Intel Core 7 253PQE wins every category, including single-thread, multithread, floating point, integer, encryption, compression, physics, random string sorting, prime number finding, and extended instructions. There is no workload category in the recorded data where the AMD part comes out ahead.

The AMD part's only advantages are structural rather than performance-based. Its 15 W TDP makes it suitable for power-constrained mobile designs, and its AMD Socket FP5 platform targets a different market segment than the Intel part's desktop Socket 1700. The Radeon Vega 8 integrated graphics and the older Picasso architecture position it as an entry-level mobile option. The Intel Core 7 253PQE, with its 125 W TDP, PCIe Gen 5 support, ECC memory support, DDR5 compatibility, and 33 MB L3 cache, is positioned for high-performance desktop workloads. The 91st percentile ranking for the Intel part versus the 62nd percentile for the AMD part summarizes the overall standing: the Intel processor competes with flagship parts like the Intel Core i9-14900HX and AMD Ryzen AI Max 390, while the AMD processor sits near the AMD EPYC 7272 and Intel Core i9-10920X in aggregate score. For any user choosing between these two based on the recorded data, the Intel Core 7 253PQE is the stronger performer in every measured dimension.
