Intel Core 3 N355 vs Intel Core 5 223PTE Comparison

Where Each One Wins

The Intel Core 3 N355 and Intel Core 5 223PTE occupy completely different segments of the desktop and mobile spectrum, and the recorded data reflects that split clearly. The Core 3 N355 is a mobile part with a complete benchmark suite on file, while the Core 5 223PTE has no recorded benchmark scores at all in the database. That absence shapes the entire comparison: every measured performance figure belongs to the N355, and the 223PTE must be evaluated through its architectural and specification profile rather than direct test results.

The N355 wins outright on availability of measured data. Its benchmark suite spans Cinebench R15, R20, and R23 in both single-core and multi-core configurations, plus a full Passmark battery covering integer math, floating point math, encryption, compression, physics, and sorting workloads. The highest recorded multi-core result is 5262 points in Cinebench R23, while the single-core result in the same test reaches 1039 points. In Passmark multithread testing, the N355 records 10174 points, and its single-thread Passmark score is 2153 points. These figures place the N355 at the 68th percentile among all CPUs in the database, which means it sits above the median of the entire tracked processor population.

The 223PTE wins on raw specification headroom. It carries a boost clock of 5.40 GHz compared to 3.90 GHz for the N355, a 2 MB per-core L2 cache configuration versus a 2 MB shared L2 on the N355, and a 24 MB shared L3 cache versus 6 MB shared. The 223PTE also supports 16 PCIe Gen 5 lanes from the CPU, while the N355 provides 9 Gen 3 lanes. Dual-channel memory on the 223PTE delivers 89.6 GB/s of bandwidth, versus single-channel 38.4 GB/s on the N355. These are structural advantages that favor the 223PTE for workloads that scale with memory bandwidth, cache capacity, and high clock ceilings, but the database holds no benchmark numbers to confirm how those advantages translate into actual scores.

The N355 wins on power efficiency at the specification level. Its 15 W TDP compares to 45 W for the 223PTE, a threefold difference in thermal design power. The N355 also supports LPDDR5 memory in addition to DDR4 and DDR5, which aligns with its mobile positioning. The 223PTE supports DDR4 and DDR5 but not LPDDR5, and it targets the desktop segment with a locked multiplier.

Architecture Differences

The two processors come from different architectural families. The N355 is built on the Twin Lake architecture, listed in the database under the Alder Lake-N generation, and uses the Twin Lake codename. The 223PTE uses the Bartlett Lake codename and is classified under the Core 5 (Bartlett Lake) generation. Both are fabricated on a 10 nm process at Intel, so the underlying lithography is identical, but the core designs and platform integrations diverge sharply.

Core counts match at 8 physical cores, but thread counts do not. The N355 runs 8 threads with no simultaneous multithreading, while the 223PTE runs 16 threads, indicating hyperthreading support that doubles the logical thread count. The N355 offers 96 KB of L1 cache per core, while the 223PTE offers 80 KB per core. The N355 shares 2 MB of L2 across the chip, but the 223PTE provides 2 MB per core, which for an 8-core part amounts to a much larger aggregate L2. The L3 cache difference is substantial: 6 MB shared on the N355 versus 24 MB shared on the 223PTE.

Memory controllers differ as well. The N355 uses a single-channel memory bus with 38.4 GB/s of bandwidth and supports DDR4, DDR5, and LPDDR5. The 223PTE uses a dual-channel bus with 89.6 GB/s of bandwidth and supports DDR4 and DDR5, but not LPDDR5. ECC memory support is present on the 223PTE and absent on the N355. PCIe connectivity differs by generation and lane count: Gen 3 with 9 lanes on the N355, Gen 5 with 16 lanes on the 223PTE.

The integrated graphics unit is the same on both parts: UHD Graphics 770. Socket and platform targets are entirely different. The N355 uses Intel BGA 1264, a soldered mobile package, while the 223PTE uses Intel Socket 1700, a desktop LGA socket. The N355 is listed as a Mobile segment part, while the 223PTE is listed as Desktop. Both parts are Active in production status, and both have locked multipliers.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, and the 223PTE has no recorded benchmark scores. Direct numerical comparison is therefore impossible for any individual test. The N355's scores stand alone as the only measured data points in this pairing.

The N355's Cinebench R23 multi-core score of 5262 points and single-core score of 1039 points give a rough ratio of about 5.1:1 between multi-threaded and single-threaded throughput. In Cinebench R20, the multi-core score is 3612 points and the single-core score is 509 points. In Cinebench R15, the multi-core score is 822 points and the single-core score is 168 points. The Passmark results show a multithread score of 10174, a single-thread score of 2153, integer math at 33894, floating point math at 22695, data encryption at 8121, data compression at 117435, extended instructions at 5968, physics at 625, random string sorting at 14706, and prime number finding at 27.

The 223PTE's nearest rivals list is empty, and its average benchmark score is recorded as 0, with a percentile of 50. The N355, by contrast, has an average benchmark score of 13492 and sits at the 68th percentile. Its nearest rivals include the Intel Core i3-12100F at 13494 average score with a 0% delta, the Intel Core i5-9500 at 13452 with a 0.3% delta, the Intel Core 5 120UL at 13594 with a -0.8% delta, and the Intel Core i7-1250U at 13351 with a 1.1% delta. The N355 is effectively a statistical tie with the Core i3-12100F, within 0.3% of the Core i5-9500, 0.8% below the Core 5 120UL, and 1.1% above the Core i7-1250U.

Because the 223PTE has no scores, any statement about its performance relative to the N355 must rely on specification-level inference. The 223PTE's higher boost clock, larger caches, dual-channel memory, and higher TDP all point toward higher multi-threaded and memory-sensitive performance, but the database records no confirmation.
