Intel Core 3 N355 vs Intel Core 5 223PE Comparison

The Intel Core 3 N355 and Intel Core 5 223PE represent two very distinct approaches to Intel’s processor lineup. The data shows the Core 5 223PE is overwhelmingly faster, but the Core 3 N355 occupies a completely different power and efficiency class. This analysis compares the recorded benchmark scores and architectural specifications to clarify where each processor stands.

Head-to-Head Benchmarks

The benchmark results are one-sided. The Intel Core 5 223PE wins all 17 recorded head-to-head tests, with no wins for the Intel Core 3 N355. The margins are substantial across every category, from single-threaded tasks to heavy multi-core workloads.

In Cinebench testing, the Core 5 223PE delivers massive leads. In Cinebench R23 multi-core, it scores 26455 against 5262 for the Core 3 N355, a delta of -80.1%. The single-core R23 result shows a similar pattern: 3734 versus 1039, a -72.2% delta. Cinebench R20 multi-core shows 11111 against 3612 (-67.5%), and R20 single-core shows 1568 versus 509 (-67.5%). Cinebench R15 multi-core shows 2666 versus 822 (-69.2%), while R15 single-core shows 376 versus 168 (-55.3%).

The PassMark suite confirms the trend. In integer math, the Core 5 223PE scores 99819 against 33894, a -66% delta. Floating point math shows 76468 versus 22695 (-70.3%).

Single-thread performance is the closest contest, but the Core 5 223PE still leads significantly. PassMark single-thread shows 4219 versus 2153, a -49% delta. This is the smallest margin in the entire dataset, which indicates that the Core 3 N355’s architecture is relatively competitive in lightly threaded work, but the Core 5 223PE’s higher clock speed still dominates.

The average benchmark score tells the broader story. The Core 5 223PE averages 40585 points, while the Core 3 N355 averages 13492 points. This places the Core 5 223PE at the 87th percentile of all CPUs, while the Core 3 N355 sits at the 68th percentile. The nearest rivals corroborate these positions: the Core 5 223PE trades within 0.3% of the Intel Core 7 253PE and the AMD Ryzen AI 5 PRO 435G, while the Core 3 N355 sits within 1.1% of the Intel Core i7-1250U.

Architecture Differences

The architectural gap explains the performance chasm. The Intel Core 3 N355 uses the Twin Lake architecture, also known by the codename Twin Lake, and is part of the Alder Lake-N generation. It is built on Intel’s 10 nm process. The Intel Core 5 223PE uses the Bartlett Lake codename and belongs to the Core 5 generation, also built on a 10 nm process, but with a different design philosophy.

Core counts are identical at 8 cores, but thread counts differ. The Core 3 N355 has 8 threads, meaning no simultaneous multithreading. The Core 5 223PE has 16 threads, enabling full hyperthreading. This doubles the logical processing capacity and is a primary driver of the multi-core benchmark gaps.

Clock speeds differ dramatically. The Core 3 N355 has a base clock of 1.90 GHz and a boost clock of 3.90 GHz. The Core 5 223PE has a base clock of 2.90 GHz and a boost clock of 5.20 GHz. The higher boost clock directly explains the single-thread advantage.

Cache hierarchies are entirely different. The Core 3 N355 has 96 KB of L1 cache per core, 2 MB of shared L2 cache, and 6 MB of shared L3 cache. The Core 5 223PE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The much larger L3 cache on the Core 5 223PE supports its heavier workloads.

Memory support also diverges. The Core 3 N355 supports DDR4, DDR5, and LPDDR5, but only on a single-channel memory bus with 38.4 GB/s bandwidth. The Core 5 223PE supports DDR4 and DDR5 on a dual-channel bus with 89.6 GB/s bandwidth. The Core 5 223PE also supports ECC memory, which the Core 3 N355 does not.

PCIe connectivity differs. The Core 3 N355 provides PCIe Gen 3 with 9 lanes, while the Core 5 223PE provides PCIe Gen 5 with 16 lanes. The newer and wider PCIe implementation on the Core 5 223PE allows for faster expansion devices.

Integrated graphics differ. The Core 3 N355 uses UHD Graphics 770, while the Core 5 223PE uses UHD Graphics 730. The Core 3 N355 targets mobile platforms with an Intel BGA 1264 socket, while the Core 5 223PE targets desktop platforms with an Intel Socket 1700. The Core 3 N355 has a 15 W TDP, while the Core 5 223PE has a 65 W TDP, reflecting the mobile versus desktop positioning.

The Verdict

The data indicates a clear performance hierarchy. The Intel Core 5 223PE is the superior processor for almost all compute tasks. Its 16 threads, 5.20 GHz boost clock, 24 MB L3 cache, and dual-channel memory with 89.6 GB/s bandwidth deliver benchmark scores that are multiple times higher than the Core 3 N355 across every test. The 87th percentile ranking versus the 68th percentile ranking confirms the placement.

The Intel Core 3 N355 is not without merit, but its role is different. It uses a 15 W TDP, a single-channel memory bus, and a mobile BGA socket. It is designed for compact, low-power systems where the 38.4 GB/s bandwidth and 8 threads are acceptable. Its benchmark scores, such as 5262 in Cinebench R23 multi-core and 2153 in PassMark single-thread, indicate modest capability.

For anyone building a desktop system that requires throughput, the Core 5 223PE is the only rational choice. The benchmark margins are so large that no workload in the dataset favors the Core 3 N355. For a fanless or battery-powered mobile device, the Core 3 N355’s lower TDP is relevant, but the performance sacrifice is severe.

The launch MSRP of the Core 5 223PE is $232, which reflects its higher positioning. The Core 3 N355 has no recorded launch MSRP.

Where Each One Wins

The Intel Core 5 223PE wins in every measured workload. It excels in multi-threaded rendering, as shown by the Cinebench R23 multi-core score of 26455, which is 80.1% ahead of the Core 3 N355. It wins in integer and floating point math, data compression, encryption, and physics simulations. Its single-thread performance is also superior, with a PassMark single-thread score of 4219 versus 2153. The dual-channel memory and 89.6 GB/s bandwidth support memory-intensive tasks, and the PCIe Gen 5 interface enables high-speed storage and graphics.

The Intel Core 3 N355 has no benchmark wins. Its strengths are structural rather than performance-based. It has a 15 W TDP, making it suitable for thermally constrained mobile designs. It supports LPDDR5 memory, which is common in low-power laptops. Its integrated UHD Graphics 770 is present, though its performance is not benchmarked here. The single-channel memory bus is a limitation, but it aligns with the processor’s low-power intent.

The data shows that the Core 5 223PE is the processor for compute-heavy desktop workloads. The Core 3 N355 is the processor for minimal-power mobile systems where the benchmark deficit is an acceptable trade-off for its efficiency profile.
