AMD Ryzen AI 9 465 vs Intel Core 3 N355 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep: the AMD Ryzen AI 9 465 wins all 15 head-to-head benchmark comparisons against the Intel Core 3 N355, with zero wins for Intel in the tested suite. The magnitude of the victories varies widely, from a relatively modest single-core margin to enormous multi-core and instruction-level gaps.

The largest single delta appears in the PassMark find prime numbers test, where AMD scores 124 against Intel's 27, a 359.3% advantage. This is a highly parallel workload that benefits from the AMD's 10 cores and 20 threads, but the scale of the gap suggests architectural efficiency differences beyond raw core count. Extended instructions show a similar pattern: AMD scores 24773, Intel scores 5968, a 315.1% delta. That test isolates SIMD and newer instruction set capabilities, and the 4 nm Zen 5 implementation clearly executes these far more efficiently than the 10 nm Twin Lake design.

Multi-core rendering benchmarks reinforce the pattern. In Cinebench R23 multicore, AMD posts 17462.5 against Intel's 5262, a 231.9% advantage. Cinebench R15 multicore shows 2672.5 versus 822, a 225.1% delta. These are among the largest multicore deltas in the dataset, indicating that heavily threaded content creation workloads will see roughly three times the throughput on the AMD part. Data compression tells a similar story: 349463 versus 117435, a 197.6% delta. Integer math shows 99156 versus 33894, a 192.5% advantage, while floating point math delivers 62411 versus 22695, a 175% delta. The PassMark multithread score lands at 28986 versus 10174, a 184.9% gap.

The single-core results are narrower but still clearly favor AMD. Cinebench R23 single core shows 1996.5 versus 1039, a 92.2% delta. Cinebench R15 single core gives 247 versus 168, a 47% delta. PassMark single thread records 3750 versus 2153, a 74.2% advantage. Even the smallest delta in the entire suite, the 47% lead in Cinebench R15 single core, represents a substantial per-thread performance edge. This matters for lightly threaded applications where the Intel part might otherwise compete on efficiency.

Other workloads follow the same direction. Data encryption shows 17601 versus 8121, a 116.7% delta. Physics simulation records 1689 versus 625, a 170.2% gap. Random string sorting lands at 37379 versus 14706, a 154.2% delta. In every case, the AMD processor at least doubles the Intel score, and in several tests it more than triples it. The consistency of these results, across rendering, encryption, compression, math, and sorting, indicates a broad performance advantage rather than a workload-specific quirk.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 9 465 uses the Zen 5 architecture with the Gorgon Point codename, built on a 4 nm process at TSMC. The Intel Core 3 N355 uses the Twin Lake architecture, which the database records as part of the Alder Lake-N generation, manufactured on Intel's 10 nm process. The process node gap alone, 4 nm versus 10 nm, explains part of the efficiency and clock headroom differences.

Core and thread configurations diverge sharply. AMD provides 10 cores and 20 threads, while Intel provides 8 cores and 8 threads. The Intel part has no simultaneous multithreading, so its thread count equals its core count. AMD's 20 threads give the scheduler twice as many logical processors to fill, which directly contributes to the multicore benchmark results. The cache hierarchy also differs. AMD allocates 80 KB of L1 per core and 1 MB of L2 per core, with a shared 16 MB L3 cache. Intel allocates 96 KB of L1 per core, a shared 2 MB L2, and a shared 6 MB L3. AMD's larger total L2 and L3 capacities provide more on-die data for frequently accessed working sets.

Clock speeds favor AMD as well. The AMD base clock is 2.00 GHz with a boost of 5.00 GHz. The Intel base clock is 1.90 GHz with a boost of 3.90 GHz. The 1.1 GHz boost advantage helps explain the single-core deltas. Power envelopes differ: AMD is rated at 28 W TDP, Intel at 15 W TDP. Despite the higher TDP, AMD's 4 nm process allows higher clocks while remaining in a mobile-class power range.

Memory support separates the two meaningfully. AMD supports DDR5 and LPDDR5X over a dual-channel bus, delivering 89.6 GB/s of bandwidth. Intel supports DDR4, DDR5, and LPDDR5, but only over a single-channel bus, capping bandwidth at 38.4 GB/s. That 51.2 GB/s difference, more than double Intel's available bandwidth, feeds the AMD's larger cache and higher core count in memory-intensive tests. PCIe connectivity also differs: AMD provides Gen 4 with 16 lanes, Intel provides Gen 3 with 9 lanes. Both are mobile parts with integrated graphics: AMD uses the Radeon 880M, Intel uses UHD Graphics 770. Neither supports ECC memory, and neither has an unlocked multiplier.

The sockets are incompatible: AMD uses Socket FP8, Intel uses BGA 1264. Release dates in the database show Intel launched on 2025-01-06 while AMD launched on 2025-12-31, placing the AMD part nearly a year later in the product cycle.

Where Each One Wins

The AMD Ryzen AI 9 465 wins in every recorded benchmark category. For heavily threaded workloads, the lead is massive. Cinebench R23 multicore, Cinebench R15 multicore, PassMark multithread, integer math, floating point math, data compression, and extended instructions all show AMD at least 175% ahead, with extended instructions and prime number finding exceeding 300%. Content creation, 3D rendering, video encoding, scientific computation, and any workload that scales across 20 threads will favor the AMD part decisively.

For single-threaded tasks, AMD still leads, but by a smaller margin. Cinebench R23 single core shows a 92.2% advantage, PassMark single thread shows 74.2%, and Cinebench R15 single core shows 47%. Applications that rely on one or two threads, such as older games, lightweight office tasks, or scripted automation, will still run faster on AMD, though the gap narrows to under double in some tests.

The Intel Core 3 N355 has no benchmark victories in the recorded data. Its advantages are structural rather than performance-based. At 15 W TDP versus 28 W, it draws less power. It supports DDR4 in addition to DDR5 and LPDDR5, which could allow lower-cost memory configurations. Its BGA 1264 socket and 9 PCIe Gen 3 lanes target compact, low-power designs. For fanless or ultra-low-power systems where absolute performance is secondary, the Intel part offers a lower power envelope. But in every measured workload, the AMD processor delivers higher scores, often by a factor of two to four.

The Verdict

The data presents an unambiguous result. The AMD Ryzen AI 9 465 outperforms the Intel Core 3 N355 in every benchmark recorded in the database, with an average benchmark score of 43431 against Intel's 13492. The AMD part sits at the 88th percentile among all CPUs, while Intel sits at the 68th percentile. The nearest rivals for AMD include the AMD Ryzen AI Max PRO 385 at 43326 (0.2% behind) and the Intel Core Ultra 9 386H at 43210 (0.5% behind), placing the Ryzen AI 9 465 in the upper tier of mobile processors. Intel's nearest rivals include the Intel Core i3-12100F at 13494 (0% delta) and the Intel Core i5-9500 at 13452 (0.3% ahead), showing the Core 3 N355 competes with desktop chips from several generations ago.

For users who need multicore throughput, the choice is clear. The AMD part delivers 231.9% higher Cinebench R23 multicore scores and 184.9% higher PassMark multithread scores. For single-thread responsiveness, AMD leads by 74.2% in PassMark single thread. Memory bandwidth favors AMD by a factor of more than two, and the PCIe Gen 4 interface doubles Intel's Gen 3 lane count.

The Intel Core 3 N355 remains an option only for designs where the 15 W TDP and BGA 1264 socket fit a specific low-power footprint. Its support for DDR4 memory and its earlier release date may suit cost-constrained embedded or entry-level mobile systems. But the benchmark data provides no performance scenario where Intel wins. Anyone selecting between these two processors on the basis of measured capability should choose the AMD Ryzen AI 9 465, which dominates the recorded suite across rendering, encryption, compression, math, sorting, and single-thread tests alike.
