AMD Ryzen 3 3100U vs Intel Core 9 273PE Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep: the Intel Core 9 273PE wins all 11 shared benchmark comparisons, with no wins recorded for the AMD Ryzen 3 3100U. The largest margin appears in floating point math, where Intel scores 107884 against AMD's 5854, a delta of -94.6% from AMD's perspective. Integer math follows a similar pattern, with Intel at 139410 versus 8873, a -93.6% difference.

The single-thread comparison narrows the gap considerably, but Intel still leads by a substantial margin. The Intel Core 9 273PE scores 3650 in passmark single thread, while the AMD Ryzen 3 3100U scores 1592, a -56.4% delta. This indicates that even in lightly threaded workloads, the Intel part holds more than double the performance of the AMD chip.

Multithreaded results amplify the separation. The Intel Core 9 273PE records 36810 in passmark multithread, compared to 3348 for the AMD Ryzen 3 3100U, a -90.9% delta. Data compression shows the same story at scale: Intel posts 405885 versus AMD's 38455, a -90.5% gap. The smallest percentage difference in the entire set is random string sorting, where Intel scores 45098 against 4666, a -89.7% delta, still a massive lead.

The average benchmark score reinforces this hierarchy. The Intel Core 9 273PE averages 49845, placing it in the 90th percentile of all CPUs in the database. The AMD Ryzen 3 3100U averages 6247, sitting in the 62nd percentile. Comparing the two directly, the Intel average is roughly 8 times higher. The nearest rivals for each chip confirm their respective tiers: the AMD Ryzen 3 3100U trades within 1.6% of parts like the Intel Core i9-7940X and Intel Core i9-10920X, while the Intel Core 9 273PE sits within 1.2% of the AMD Ryzen AI 9 HX PRO 370 and 1.1% of the Intel Core i9-13980HX.

Architecture Differences

The two processors come from different design generations and target different market segments. The AMD Ryzen 3 3100U uses the Picasso codename, built on the Zen+ architecture at a 12 nm process node from GlobalFoundries. It belongs to the 3000 series and is classified as a mobile part. The Intel Core 9 273PE uses the Bartlett Lake codename, built on a 10 nm process at Intel's own foundry, and is classified as a desktop part.

The Intel Core 9 273PE supports both DDR4 and DDR5, also dual-channel, but with 89.6 GB/s of bandwidth and ECC enabled. PCIe generations differ: the AMD chip uses Gen 3, while the Intel chip uses Gen 5 with 16 lanes available to the CPU. Integrated graphics also differ, with the AMD part using Radeon Vega 8 and the Intel part using UHD Graphics 730.

The release dates in the database place the Intel Core 9 273PE earlier, listed as 2026-03-08, while the AMD Ryzen 3 3100U is listed as 2026-05-31. Both parts are marked as active production. Neither has an unlocked multiplier. The AMD part number is YM3100C4T2OFG, and the Intel part number is SA4QD. The Intel chip has a launch MSRP of $549.

The Verdict

The benchmark data leaves no ambiguity. The Intel Core 9 273PE outperforms the AMD Ryzen 3 3100U in every recorded shared test, with deltas ranging from -56.4% in single-thread work to -94.6% in floating point math. The Intel chip also carries a much higher average benchmark score, 49845 versus 6247, and a higher percentile ranking, 90 versus 62.

The Intel Core 9 273PE is the appropriate choice for workloads that demand high core counts, high memory bandwidth, and ECC support. Its 12 cores and 24 threads, 36 MB of shared L3 cache, 89.6 GB/s memory bandwidth, and DDR5 support give it a structural advantage that the benchmark results confirm. Its nearest rivals in the database, such as the Intel Core i9-13980HX and AMD Ryzen AI 9 HX PRO 370, sit within 1.2% of its average score, placing it in the high-end desktop tier.

The AMD Ryzen 3 3100U, by contrast, is a low-power mobile part. Its 15 W TDP, 2 cores, and 2 threads position it for efficiency-constrained environments. Its nearest rivals, including the AMD Ryzen Threadripper 1950X and AMD EPYC 7272, sit within 1.6% of its average score, which places it in a completely different performance class. The data shows no scenario in the shared benchmark set where the AMD chip wins.

Where Each One Wins

The Intel Core 9 273PE wins in every category where both chips have recorded scores. In compression, encryption, extended instructions, prime number finding, floating point math, integer math, multithreaded work, physics, random string sorting, and single-thread tests, the Intel part leads by at least 89.7% and by as much as 94.6%.

The AMD Ryzen 3 3100U has no benchmark wins in the head-to-head set. Its strengths are structural rather than performance-based: the 15 W TDP makes it suitable for low-power mobile designs, and its Radeon Vega 8 integrated graphics provide a different visual output path than the Intel UHD Graphics 730. The AMD chip's smaller die, at 210 mm², and its 12 nm process from GlobalFoundries are recorded facts, but they do not translate into any measured performance advantage in the database.

For users selecting on measured outcomes, the Intel Core 9 273PE is the only option with a winning record. For users constrained by power envelopes or mobile form factors, the AMD Ryzen 3 3100U occupies that niche, but the recorded benchmarks give no indication that it competes on speed with the Intel part.
