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

The AMD Ryzen 3 3100U and the Intel Core 7 253PTE occupy very different corners of the processor landscape, and the benchmark data reflects that divide clearly. The Ryzen 3 3100U is a 2-core, 2-thread mobile part built on the older Picasso architecture, while the Core 7 253PTE is a 10-core, 20-thread desktop processor from the Bartlett Lake generation. The recorded measurements show a consistent and substantial performance gap across every single test, with the Intel part winning all 11 head-to-head benchmarks. The average benchmark score for the AMD chip is 6247, placing it at the 62nd percentile of all CPUs, while the Intel chip averages 34962, which lands it at the 84th percentile.

Head-to-Head Benchmarks

The most lopsided result in the comparison is in PassMark integer math, where the Intel Core 7 253PTE scores 119552 against the AMD Ryzen 3 3100U's 8873, a delta of -92.6%. That is the largest percentage gap in the entire head-to-head set, and it reflects the massive difference in core count and thread count. Floating point math tells a similar story: Intel scores 67209 versus AMD's 5854, a delta of -91.3%. These two workloads are heavily parallel, so the Intel part's 10 cores and 20 threads give it an overwhelming advantage over the AMD chip's 2 cores and 2 threads.

The gap narrows somewhat in single-threaded workloads, but it remains decisive. In PassMark single-thread, the Intel part scores 3794 while the AMD chip scores 1592, a delta of -58%. That is the smallest percentage difference in the entire set, but it still represents Intel delivering more than double the single-core performance. The same scores appear under the PassMark singlethread test name, confirming the result. This single-thread advantage is important because it indicates that the Intel part is not just winning through raw core count; its per-core performance is also significantly stronger.

Data compression and encryption workloads follow the same pattern. In data compression, Intel scores 275828 against AMD's 38455, a delta of -86.1%. In data encryption, Intel scores 15500 against AMD's 1972, a delta of -87.3%. Extended instructions show Intel at 17099 versus AMD's 2116, a delta of -87.6%. The prime number finding test has Intel at 82 versus AMD's 18, a delta of -78%. Random string sorting shows Intel at 28227 versus AMD's 4666, a delta of -83.5%. The physics test has Intel at 1318 versus AMD's 232, a delta of -82.4%. The multithread test rounds out the set with Intel at 25031 against AMD's 3348, a delta of -86.6%.

Across all 11 head-to-head benchmarks, the Intel Core 7 253PTE wins every one. The AMD Ryzen 3 3100U records zero wins. The deltas range from -58% in single-threaded work to -92.6% in integer math, meaning the smallest Intel advantage is still a 58% lead. The data shows no workload category where the AMD chip comes out ahead, even in the tests that typically favor lower-power or older architectures.

Where Each One Wins

The Intel Core 7 253PTE wins in every measured category, so the question of where each one wins is really a question of degree. In heavily parallel workloads like integer math, floating point math, and multithreaded tests, the Intel part's advantage is extreme, with deltas of -92.6%, -91.3%, and -86.6% respectively. These are workloads that can use all 20 threads, and the Intel part's 10 cores and 20 threads dominate the AMD chip's 2 cores and 2 threads.

In memory-sensitive workloads like data compression and random string sorting, the Intel part also leads by wide margins, with deltas of -86.1% and -83.5%. The Intel part supports both DDR4 and DDR5 memory with a memory bandwidth of 89.6 GB/s, compared to the AMD part's DDR4-only support with 38.4 GB/s of bandwidth. That bandwidth advantage likely contributes to the strong showing in these data-heavy tests.

In single-threaded workloads, the Intel part's lead narrows but remains substantial. The -58% delta in PassMark single-thread means the Intel part still delivers more than double the performance. This is notable because it shows the Intel architecture's higher boost clock of 5.40 GHz, compared to the AMD part's 3.20 GHz boost, translates directly into faster per-core execution.

The AMD Ryzen 3 3100U has no benchmark category where it wins. Its only relative strength is that its single-thread deficit is smaller than its multi-thread deficit, meaning the gap is least severe in lightly threaded work. The AMD part's 15W TDP is much lower than the Intel part's 45W TDP, but the benchmark data does not show any performance benefit from that lower power draw. In every recorded test, the Intel part delivers higher scores.

The sockets are different as well: the AMD part uses AMD Socket FP5, and the Intel part uses Intel Socket 1700. The AMD part is a mobile segment processor, while the Intel part is a desktop segment processor.

Cache configurations diverge. The AMD part has 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Intel part has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. Memory support differs, with the AMD part limited to DDR4 and the Intel part supporting DDR4 and DDR5. Memory bandwidth is higher on the Intel part at 89.6 GB/s versus 38.4 GB/s. The AMD part does not support ECC memory, while the Intel part does.

PCIe support also differs by generation. The AMD part uses PCIe Gen 3, while the Intel part uses PCIe Gen 5 with 16 lanes on the CPU. The integrated graphics are different: the AMD part uses Radeon Vega 8, and the Intel part uses UHD Graphics 730. The release dates are close, with the AMD part launching on 2026-05-31 and the Intel part on 2026-03-08. The Intel part has a launch MSRP of $384. The AMD part has no listed launch MSRP. The AMD part has 4,940 million transistors on a 210 mm² die, while the Intel part has no transistor count or die size recorded.

Architecture Differences

The AMD Ryzen 3 3100U is built on the Picasso architecture, which is part of the Ryzen 3 generation using the Zen+ microarchitecture. It is manufactured on a 12 nm process at GlobalFoundries. The Intel Core 7 253PTE uses the Bartlett Lake architecture, part of the Core 7 generation, and is manufactured on a 10 nm process at Intel.

The process node difference is notable: 12 nm for AMD versus 10 nm for Intel. The AMD part's Picasso architecture is an older design, while Bartlett Lake is a newer Intel generation. The transistor counts reflect the design scale, with the AMD part packing 4,940 million transistors into a 210 mm² die. The Intel part does not have transistor or die size data recorded in the database.

Cache architecture differs in both size and organization. The AMD part uses 96 KB of L1 per core and 512 KB of L2 per core, with a shared 4 MB L3 pool. The Intel part uses 80 KB of L1 per core and 2 MB of L2 per core, with a much larger shared 33 MB L3 cache. The larger L3 cache on the Intel part is consistent with its higher thread count and more demanding desktop workloads.

The memory controller is another architectural split. The AMD part supports only DDR4, while the Intel part supports both DDR4 and DDR5. The Intel part also enables ECC memory support, which the AMD part lacks. PCIe capability is also a generation apart: AMD has Gen 3, while Intel has Gen 5 with 16 CPU lanes. The integrated graphics differ as well, with AMD using Radeon Vega 8 and Intel using UHD Graphics 730.

The Verdict

The benchmark data is unambiguous. The Intel Core 7 253PTE outperforms the AMD Ryzen 3 3100U in every single recorded test, with deltas ranging from -58% in single-thread to -92.6% in integer math. The Intel part's average benchmark score of 34962 is more than five times the AMD part's 6247, and its 84th percentile ranking versus the AMD part's 62nd percentile confirms the overall performance hierarchy.

The AMD Ryzen 3 3100U is a 15W mobile processor with 2 cores and 2 threads, designed for low-power systems. Its benchmark results place it in the lower half of the performance distribution, and it offers no workload category where it beats the Intel part. Its smaller single-thread deficit, -58%, means it is least disadvantaged in lightly threaded tasks, but it still loses those by a wide margin.

The Intel Core 7 253PTE is a 45W desktop processor with 10 cores, 20 threads, a 5.40 GHz boost clock, and support for DDR5 memory and PCIe Gen 5. Its benchmark results place it near the top of the database, and it wins every head-to-head test by a significant margin. The data shows that this is not a close comparison: the Intel part is faster in every measurable way, and the AMD part has no benchmark-based case for selection over it.
