Intel Core 3 N355 vs Intel Core 7 253PE Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep: the Intel Core 7 253PE wins all 17 head-to-head benchmark comparisons, with the Intel Core 3 N355 failing to claim a single victory. The margin of separation is substantial across every workload category, though the magnitude of the gap varies considerably by test type.

The largest single-core advantage appears in Cinebench R23 single-core, where the Core 7 253PE scores 3512 against the Core 3 N355's 1039, a delta of -70.4% for the N355. In Cinebench R20 single-core, the Core 7 253PE delivers 1475 versus 509, a -65.5% gap. Cinebench R15 single-core shows a smaller but still pronounced difference: 354 versus 168, or -52.5%. PassMark single-thread results indicate 3955 for the Core 7 253PE against 2153 for the Core 3 N355, a -45.6% delta, the narrowest single-core margin in the entire dataset.

Multi-core workloads amplify the separation further. Cinebench R23 multicore gives the Core 7 253PE a score of 24880 versus 5262, a -78.9% delta, the largest percentage gap recorded in any benchmark. Cinebench R20 multicore shows 10449 against 3612, a -65.4% difference, while Cinebench R15 multicore records 2507 versus 822, a -67.2% gap. PassMark multithread scores 29271 for the Core 7 253PE and 10174 for the Core 3 N355, a -65.2% delta.

Specialized compute workloads follow the same pattern. PassMark integer math shows 114158 versus 33894, a -70.3% gap. Floating-point math records 80870 versus 22695, a -71.9% delta. Extended instructions deliver 21806 versus 5968, a -72.6% difference. Prime number finding produces the second-largest gap: 138 versus 27, a -80.4% delta. Physics scores 1845 versus 625, a -66.1% difference. Data compression shows 339133 versus 117435, a -65.4% gap. Data encryption records 18385 versus 8121, or -55.8%. Random string sorting yields 32777 versus 14706, a -55.1% delta, the second-narrowest margin after single-thread performance.

The narrowest gaps, around -45% to -55%, appear in single-thread tests and encryption, indicating that per-core efficiency differences are smaller than scaling differences. The widest gaps, above -70%, cluster in heavily multi-threaded and compute-intensive workloads, consistent with the Core 7 253PE's larger core and thread count.

Architecture Differences

The two processors diverge sharply in their fundamental design. The Intel Core 3 N355 uses 8 cores and 8 threads with no hyper-threading, while the Intel Core 7 253PE provides 10 cores and 20 threads, doubling thread count through simultaneous multithreading. Core counts differ by 2, but thread counts differ by 12.

Clock speeds show a significant separation. The Core 3 N355 bases at 1.90 GHz and boosts to 3.90 GHz. The Core 7 253PE bases at 2.50 GHz and boosts to 5.50 GHz, a 1.60 GHz higher boost ceiling. Thermal design power differs by 50 watts: 15 W for the Core 3 N355 versus 65 W for the Core 7 253PE, reflecting the latter's desktop orientation and higher sustained power envelope.

Cache hierarchies are structured differently. The Core 3 N355 allocates 96 KB of L1 per core, a 2 MB shared L2, and a 6 MB shared L3. The Core 7 253PE uses 80 KB of L1 per core, a 2 MB per-core L2, and a 33 MB shared L3. The total L3 advantage for the Core 7 253PE is 27 MB, and its per-core L2 allocation scales with core count rather than being pooled.

Process nodes both list as 10 nm from Intel's foundry, so the manufacturing process is identical. The architectural codenames differ: Twin Lake for the Core 3 N355 versus Bartlett Lake for the Core 7 253PE. The Core 3 N355 is categorized under the Core 3 (Alder Lake-N) generation, while the Core 7 253PE belongs to the Core 7 (Bartlett Lake) generation.

Memory support diverges. The Core 3 N355 supports DDR4, DDR5, and LPDDR5 across a single-channel memory bus with 38.4 GB/s bandwidth. The Core 7 253PE supports DDR4 and DDR5 across a dual-channel bus with 89.6 GB/s bandwidth, over twice the memory throughput. The Core 7 253PE also supports ECC memory; the Core 3 N355 does not.

PCIe capabilities differ substantially. The Core 3 N355 provides PCIe Gen 3 with 9 CPU lanes, while the Core 7 253PE provides PCIe Gen 5 with 16 CPU lanes. Integrated graphics also differ: the Core 3 N355 uses UHD Graphics 770, while the Core 7 253PE uses UHD Graphics 730.

Sockets and market segments reflect intended use cases. The Core 3 N355 fits Intel BGA 1264 and targets mobile. The Core 7 253PE fits Intel Socket 1700 and targets desktop. Release dates differ by over a year: the Core 3 N355 launched on 2025-01-06, while the Core 7 253PE launched on 2026-03-08. Both carry active production status, and neither has an unlocked multiplier.

The Verdict

The data supports a clear performance hierarchy. The Intel Core 7 253PE dominates every measured workload, with its smallest advantages appearing in single-thread tests and its largest in multi-threaded and compute-heavy tasks. The average benchmark score of 40557 versus 13492 places the Core 7 253PE at the 87th percentile against the Core 3 N355's 68th percentile, a 19-point percentile separation.

The Core 7 253PE's nearest rivals include the Intel Core 5 223PE with an average score of 40585 (-0.1% delta), the Intel Core Ultra X7 368H at 40518 (+0.1%), the Intel Xeon 6357P at 40630 (-0.2%), and the AMD Ryzen 9 7940H at 40431 (+0.3%). These near-identical scores indicate the Core 7 253PE sits in a tightly contested performance tier, matching or slightly trailing its closest competitors.

The Core 3 N355's nearest rivals are the Intel Core i3-12100F at 13494 (0% delta), the Intel Core i5-9500 at 13452 (+0.3%), the Intel Core 5 120UL at 13594 (-0.8%), and the Intel Core i7-1250U at 13351 (+1.1%). Its average score aligns closely with this group, placing it in a lower-performance mobile tier.

For mobile, low-power applications, the Core 3 N355's 15 W TDP, BGA 1264 socket, and LPDDR5 support fit a compact, power-conscious design. For desktop workloads requiring maximum throughput, the Core 7 253PE's 65 W TDP, dual-channel memory, PCIe Gen 5, and ECC support present a more capable platform. The 5.50 GHz boost clock and 33 MB L3 cache give the Core 7 253PE a clear advantage in latency-sensitive and heavily threaded scenarios. The Core 3 N355's 3.90 GHz boost and 6 MB L3 cache limit its ceiling in sustained compute.

The launch MSRP for the Core 7 253PE is $384, recorded once here; the Core 3 N355 has no recorded launch MSRP. Production status for both is Active, with the Core 7 253PE releasing on 2026-03-08 and the Core 3 N355 on 2025-01-06.
