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

Head-to-Head Benchmarks

The benchmark data records a complete sweep for the Intel Core 7 253PE across all 11 shared tests. The AMD Ryzen 3 3100U does not win a single head-to-head comparison. The margins are substantial, starting with the smallest gap in single-thread performance and widening dramatically in multi-threaded workloads.

In single-thread tests, the Intel part scores 3955 against 1592 for the AMD chip, a delta of -59.7%. This means the Intel processor delivers more than double the per-core throughput in the recorded Passmark single-thread workload. The gap is consistent across both the passmark_single_thread and passmark_singlethread entries, which are duplicate measurements.

The multi-threaded results show an even larger divide. In passmark_multithread, the Intel Core 7 253PE records 29271 while the Ryzen 3 3100U manages 3348, a delta of -88.6%. The Intel processor is roughly 8.7 times faster in this aggregate workload, reflecting its 10 cores and 20 threads against the AMD chip's 2 cores and 2 threads.

Data compression follows a similar pattern. The Intel part scores 339133 versus 38455 for the AMD, a delta of -88.7%. The AMD chip's score is about 11% of the Intel result. Integer math shows a -92.2% delta, with scores of 114158 and 8873 respectively. Floating point math records 80870 for Intel and 5854 for AMD, a -92.8% delta, the largest percentage gap in the entire comparison.

The encryption workload delivers 18385 for Intel versus 1972 for AMD, a -89.3% delta. Extended instructions follow at 21806 versus 2116, a -90.3% delta. Prime number finding shows 138 versus 18, a -87% delta. Random string sorting records 32777 versus 4666, a -85.8% delta. Physics simulation completes the set with 1845 versus 232, a -87.4% delta.

The average benchmark score in the database places the Intel Core 7 253PE at 40557, while the AMD Ryzen 3 3100U sits at 6247. The Intel processor's nearest rivals include the Intel Core 5 223PE at 40585 (-0.1% delta), the Intel Core Ultra X7 368H at 40518 (+0.1% delta), the Intel Xeon 6357P at 40630 (-0.2% delta), and the AMD Ryzen 9 7940H at 40431 (+0.3% delta). The AMD Ryzen 3 3100U's nearest rivals include the AMD Ryzen Threadripper 1950X at 6231 (+0.3% delta), the AMD EPYC 7272 at 6186 (+1% delta), the Intel Core i9-10920X at 6347 (-1.6% delta), and the Intel Core i9-7940X at 6147 (+1.6% delta).

Where Each One Wins

The recorded data shows no benchmark category where the AMD Ryzen 3 3100U outperforms the Intel Core 7 253PE. Every single test in the head-to-head list favors the Intel part. The closest relative margin is in single-thread performance, where the Intel chip still leads by 59.7%. The largest margin is in floating point math, where the Intel chip leads by 92.8%.

The AMD Ryzen 3 3100U does hold a meaningful position within its own performance tier. Its average benchmark score of 6247 places it in the 62nd percentile of all CPUs in the database. Its nearest rivals are all high-core-count desktop parts, including the 16-core AMD Ryzen Threadripper 1950X and the 10-core Intel Core i9-10920X, with deltas under 2%. This indicates the Ryzen 3 3100U's recorded scores position it competitively against much larger processors, despite its modest 2-core configuration.

The Intel Core 7 253PE sits in the 87th percentile of all CPUs, with an average score of 40557. Its nearest rivals are all modern high-end parts, including the AMD Ryzen 9 7940H and Intel's own Core Ultra X7 368H, with deltas under 0.5%. The Intel part's scores cluster tightly with these competitors, suggesting it delivers performance in the same bracket as flagship mobile and desktop processors from the same generation.

For use-case analysis, the data supports a clear split. The Intel Core 7 253PE is suited for workloads that scale with core count and thread count: the multithread, integer math, floating point math, and data compression tests all show gains above 85% over the AMD chip. The AMD Ryzen 3 3100U, with its 2 cores and 2 threads, is positioned for basic single-threaded tasks, though even there the Intel part leads by nearly 60%. The AMD chip's 15-watt TDP and 12 nm process suggest a low-power mobile design, while the Intel part's 65-watt TDP and 10 nm process indicate a desktop-oriented part.

Architecture Differences

The two processors come from different design generations and market segments. The AMD Ryzen 3 3100U uses the Picasso codename, which the database lists as a Zen+ (Picasso) generation part. It is built on a 12 nm process at GlobalFoundries, with 4,940 million transistors on a 210 mm² die. The Intel Core 7 253PE uses the Bartlett Lake codename, a Core 7 generation part built on a 10 nm process at Intel. The database records no transistor count or die size for the Intel chip.

Core and thread counts differ fundamentally. The AMD part has 2 cores and 2 threads, with no simultaneous multithreading. The Intel part has 10 cores and 20 threads, doubling its thread count through hyper-threading. Base clocks are 1.90 GHz for the AMD chip and 2.50 GHz for the Intel chip. Boost clocks are 3.20 GHz and 5.50 GHz respectively.

Cache hierarchies also differ. The AMD Ryzen 3 3100U has 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Intel Core 7 253PE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The Intel part's L3 cache is more than eight times larger than the AMD part's total L3 allocation.

Memory support diverges as well. The AMD chip supports DDR4 only, with dual-channel memory and a recorded bandwidth of 38.4 GB/s. The Intel chip supports both DDR4 and DDR5, also dual-channel, with a recorded bandwidth of 89.6 GB/s. The Intel part supports ECC memory, while the AMD part does not. PCIe capabilities differ: the AMD chip uses Gen 3, while the Intel chip uses Gen 5 with 16 lanes from the CPU.

Integrated graphics are present on both parts. The AMD Ryzen 3 3100U uses Radeon Vega 8, while the Intel Core 7 253PE uses UHD Graphics 730. The AMD part targets the mobile segment with an AMD Socket FP5, while the Intel part targets the desktop segment with an Intel Socket 1700. The Intel part's launch MSRP is $384, recorded once here.

The Verdict

The data supports only one conclusion for performance: the Intel Core 7 253PE dominates the AMD Ryzen 3 3100U in every recorded benchmark. The smallest gap is 59.7% in single-thread performance, and the largest is 92.8% in floating point math. The Intel part's average score of 40557 is roughly 6.5 times the AMD part's 6247. The Intel chip sits in the 87th percentile of all CPUs, while the AMD chip sits in the 62nd percentile.

For a user choosing between these two based strictly on benchmark results, the Intel Core 7 253PE is the clear choice for any workload involving multi-threading, data compression, encryption, mathematical computation, or physics simulation. Its 10 cores and 20 threads, 33 MB of L3 cache, DDR5 memory support, and 89.6 GB/s memory bandwidth all contribute to the recorded performance advantage.

The AMD Ryzen 3 3100U does have a role in the database's performance landscape. Its 62nd percentile ranking and close scores to much larger processors like the Threadripper 1950X and Core i9-10920X indicate that it punches above its core count in some respects. Its 15-watt TDP and mobile socket suggest a low-power design suited for compact or battery-driven systems. For a user prioritizing power efficiency over raw performance, the AMD part's specifications are relevant. However, the recorded benchmarks do not show any workload where the AMD chip wins.
