Where Each One Wins

The recorded data shows a one-sided contest. The AMD Ryzen AI 5 PRO 440 takes every measurable benchmark in the head-to-head set, so the practical question is not which chip wins a given test, but rather what kind of workload each processor can handle acceptably given its other characteristics.

The AMD chip wins heavily in processor-heavy tasks. Its largest margin comes in extended instructions where it scores 18456 against 5968 for Intel, a 209.2% lead. That result points to workloads using modern SIMD or cryptographic instruction sets. The AMD part also dominates prime-number finding with a 185.2% delta, indicating strong integer execution per cycle. Data compression shows a 118.4% advantage, and multithread performance is 106.9% ahead.

The Intel Core 3 N355 wins no benchmarks, but its 8 physical cores without hyperthreading still deliver a usable baseline for light parallel work. Its 15 W TDP and single-channel memory support suggest a power-lean platform. The database shows the Intel chip sitting at the 68th percentile overall, which puts it ahead of many older desktop parts but far behind the AMD processor's 87th percentile ranking.

For workloads where the AMD chip's advantages matter most, such as content creation, code compilation, or data processing, the choice is clear from the benchmark data. For basic office tasks, web browsing, or fanless or low-power designs where the Intel processor's lower TDP and simpler memory topology fit, the Intel part remains a functional option, though it will trail in every measured metric.

Architecture Differences

The AMD Ryzen AI 5 PRO 440 uses the Zen 5 architecture under the Gorgon Point codename, part of the Ryzen AI PRO 400 generation that combines Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC with a die size of 195 mm². The Intel Core 3 N355 uses the Twin Lake architecture, which belongs to the Core 3 generation based on Alder Lake-N heritage, and is fabricated on Intel's 10 nm process.

Cache layouts differ substantially. AMD allocates 80 KB of L1 cache per core, 1 MB of L2 per core, and 8 MB of L3 cache. Intel gives each core 96 KB of L1, but uses a shared 2 MB L2 and a shared 6 MB L3. The per-core L2 allocation for AMD means 6 MB total L2 across six cores, while Intel's shared 2 MB L2 must serve all eight cores. This difference helps explain AMD's large leads in latency-sensitive integer workloads.

Memory architecture also diverges. AMD runs a dual-channel memory bus with 89.6 GB/s bandwidth and supports DDR5 and LPDDR5X. Intel runs a single-channel bus with 38.4 GB/s and supports DDR4, DDR5, and LPDDR5. The bandwidth gap is more than 2-to-1 in AMD's favor. AMD also supports ECC memory, while Intel does not.

PCIe connectivity differs as well. AMD provides Gen 4 with 16 CPU lanes, while Intel provides Gen 3 with 9 CPU lanes. AMD's integrated graphics is the Radeon 840M, while Intel uses UHD Graphics 770. Both processors target the mobile market segment and are currently in active production.

Specification Differences

The two processors differ across nearly every specification field. The AMD Ryzen AI 5 PRO 440 has 6 cores and 12 threads, while the Intel Core 3 N355 has 8 cores and 8 threads. AMD's base clock is 2.00 GHz with a boost of 4.80 GHz, compared to Intel's 1.90 GHz base and 3.90 GHz boost.

Thermal design power separates the two clearly. AMD runs at 28 W TDP, while Intel runs at 15 W TDP. That makes the Intel part more suitable for passively cooled or very low-power chassis, though the AMD part still fits within thin-and-light mobile designs given its modest 28 W envelope.

Sockets are incompatible. AMD uses AMD Socket FP8, while Intel uses Intel BGA 1264. The process node differs: AMD is on 4 nm at TSMC, Intel is on 10 nm at Intel. AMD's die size is 195 mm²; Intel's die size is not recorded in the database.

Memory support shows the widest functional gap. AMD supports DDR5 and LPDDR5X over dual-channel with 89.6 GB/s, while Intel supports DDR4, DDR5, and LPDDR5 over single-channel with 38.4 GB/s. AMD also supports ECC memory, which Intel does not. PCIe generation and lane counts favor AMD: Gen 4 with 16 lanes versus Gen 3 with 9 lanes.

Cache specifications differ in structure. AMD has 80 KB L1 per core, 1 MB L2 per core, and 8 MB L3. Intel has 96 KB L1 per core, 2 MB shared L2, and 6 MB shared L3. Release dates also differ: Intel launched on 2025-01-06, while AMD launched on 2026-01-04. Neither processor has a recorded launch MSRP in the database.

Head-to-Head Benchmarks

The head-to-head results show AMD winning every test, with margins ranging from 52.9% to 209.2%. The smallest gap is in data encryption, where AMD scores 12418 against Intel's 8121, a 52.9% lead. This still represents a substantial advantage for encrypted storage or secure communications workloads.

The largest gap is in extended instructions. AMD scores 18456, Intel scores 5968, giving AMD a 209.2% advantage. This test typically measures AVX-512 or similar wide vector instruction throughput. The result suggests AMD's Zen 5 implementation executes these instructions far more efficiently than Intel's efficiency-core design in Twin Lake.

Prime-number finding shows a 185.2% lead for AMD, with scores of 77 versus 27. Floating-point math gives AMD an 89.2% edge, with 42934 versus 22695. Integer math shows a 94.7% lead, with 65991 versus 33894. These results indicate that AMD's per-core execution resources are significantly stronger across both integer and floating-point arithmetic.

Multithread performance shows AMD at 21054 versus Intel's 10174, a 106.9% advantage. This is notable because Intel has 8 physical cores while AMD has only 6, yet AMD still more than doubles Intel's multithread score. The combination of simultaneous multithreading, higher clocks, and better memory bandwidth overcomes Intel's two-core advantage.

Physics simulation results follow the same pattern. AMD scores 1119, Intel scores 625, giving AMD a 79% lead. Random string sorting shows AMD at 27252 versus Intel at 14706, an 85.3% advantage. Data compression shows the second-largest margin after extended instructions: AMD at 256420 versus Intel at 117435, a 118.4% lead.

Single-thread performance, which often predicts general responsiveness, gives AMD a 75.8% edge. AMD scores 3785, Intel scores 2153. The database records the same single-thread score under two test labels, both showing identical results.

Comparing to nearest rivals adds context. The AMD Ryzen AI 5 PRO 440 sits within 0.6% of the Intel Core Ultra 7 356H, which scores 41215, and the Intel Core Ultra X7 358H at 40967. The Intel Core 3 N355 matches the Intel Core i3-12100F at 13494 and sits 1.1% above the Intel Core i7-1250U at 13351.

The Verdict

The data directs a clear conclusion. The AMD Ryzen AI 5 PRO 440 outperforms the Intel Core 3 N355 in every recorded benchmark, often by margins exceeding 100%. For any workload measured in this database, the AMD processor delivers substantially higher throughput.

The AMD part wins on architecture fundamentals. Zen 5 on a 4 nm TSMC process, dual-channel memory with 89.6 GB/s bandwidth, 16 PCIe Gen 4 lanes, and ECC support make it the more capable mobile processor for demanding tasks. The 28 W TDP is higher than Intel's 15 W, but the performance return per watt is far better based on the benchmark deltas.

The Intel Core 3 N355 still has a role. Its 15 W TDP, single-channel memory, and 8 efficiency-oriented cores suit low-power designs where battery life and thermals matter more than peak performance. It supports DDR4 in addition to DDR5, which enables cheaper memory configurations in entry-level laptops. Its 68th percentile ranking means it outperforms many older desktop and mobile processors, so it is not a weak chip in absolute terms.

The choice depends on workload and platform constraints. The AMD Ryzen AI 5 PRO 440 is the correct pick for users who need strong multithread performance, fast memory bandwidth, and modern instruction set support. The Intel Core 3 N355 fits systems where 15 W power draw is a hard limit and where the workload stays light enough that the large performance gap does not matter.

The nearest rival data reinforces the separation. The AMD part competes with Intel Core Ultra 7-class processors, while the Intel Core 3 N355 competes with Intel Core i3 and i5 desktop parts from previous generations. That places these two chips in entirely different performance classes despite both being mobile processors.
