AMD Ryzen AI 7 345 vs Intel Core 3 N355 Comparison

The AMD Ryzen AI 7 345 and Intel Core 3 N355 are both mobile processors, but benchmark data places them in completely different performance tiers. Across all 15 shared head-to-head tests, the AMD Ryzen AI 7 345 records a win, with the Intel Core 3 N355 failing to take a single test. The average benchmark score for the AMD chip is 29461, placing it in the 81st percentile of all CPUs, while the Intel chip averages 13492, sitting in the 68th percentile. This is not a close contest; it is a decisive sweep in favor of the AMD part.

The Verdict

The data shows that the AMD Ryzen AI 7 345 is the clear performance leader in every measured category. Its average benchmark score of 29461 is more than double the Intel Core 3 N355’s 13492. The AMD processor’s nearest rivals include the AMD Ryzen 7 3800X with an average score of 29447, the AMD EPYC 9654 at 29409, and the Intel Core i5-13500HX at 29270, all within a 0.7% delta. This indicates the Ryzen AI 7 345 performs at a level comparable to desktop and higher-end mobile parts.

The Intel Core 3 N355, by contrast, matches the Intel Core i3-12100F (average score 13494) and the Intel Core i5-9500 (13452), with deltas of 0% and 0.3% respectively. Its performance neighborhood consists of older mainstream desktop chips and low-power mobile parts. The N355 is built for efficiency and basic workloads, but the benchmark results confirm it cannot keep pace with the Ryzen AI 7 345 in any shared test.

For users selecting between these two, the Ryzen AI 7 345 is the only choice when performance matters. The Intel Core 3 N355 may suit scenarios where power draw is the primary concern, as its 15 W TDP is lower than the Ryzen’s 28 W, but the recorded performance gap is so large that the AMD part is the default recommendation for any compute-intensive task.

Where Each One Wins

The AMD Ryzen AI 7 345 wins in all 15 head-to-head benchmark comparisons. The largest margins appear in extended instruction workloads, where it scores 17003 against the Intel’s 5968, a 184.9% advantage. Multi-threaded rendering also favors AMD heavily: Cinebench R23 multicore shows 11461 versus 5262, a 117.8% lead. Data compression tests follow the same pattern, with the AMD chip scoring 237484 against 117435, a 102.2% delta.

The Intel Core 3 N355 does not record a single win in the shared test suite. Its best relative showing comes in data encryption, where it scores 8121 against AMD’s 11814, a 45.5% deficit. That is still a substantial loss, but it is the narrowest margin of any test. The Intel part’s single-thread performance is also far behind: PassMark single-thread shows 2153 versus 3875, an 80% gap.

In workloads not covered by the shared tests, the Intel chip has its own benchmarks, such as Cinebench R20 multicore (3612) and single-core (509), which have no AMD counterpart in the data. These scores indicate the N355 is functional for light tasks, but they do not change the overall picture. The recorded data shows the Ryzen AI 7 345 dominates every comparable workload.

Architecture Differences

The AMD Ryzen AI 7 345 uses the Krackan Point codename and belongs to the Ryzen AI 300 generation, built on a hybrid Zen 5 / Zen 5c architecture. It is fabricated on a 4 nm process at TSMC. The Intel Core 3 N355 uses the Twin Lake codename with the Alder Lake-N generation label, built on Intel’s 10 nm process. These process nodes alone explain a large portion of the performance gap, as the denser 4 nm node allows higher efficiency and higher clock speeds.

Core configurations differ significantly. The AMD chip has 6 cores and 12 threads, while the Intel chip has 8 cores and 8 threads. Despite having fewer cores, the AMD part benefits from simultaneous multithreading, which doubles its thread count. The Intel part lacks hyper-threading, so its 8 cores operate as 8 threads. The benchmark results show that AMD’s 6 cores with 12 threads outperform Intel’s 8 cores in every test, confirming that core count alone does not determine performance.

Cache hierarchies also differ. The AMD chip has 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3. The Intel chip has 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. Intel’s larger L3 cache (6 MB versus 4 MB) does not translate into a performance advantage in the recorded tests. Memory support also differs: AMD supports DDR5 and LPDDR5X with dual-channel operation and 89.6 GB/s of bandwidth, while Intel supports DDR4, DDR5, and LPDDR5 with single-channel operation and 38.4 GB/s of bandwidth. The AMD part’s memory bandwidth is more than double Intel’s, which heavily impacts multi-threaded and memory-intensive workloads.

PCIe support differs as well. The AMD chip provides Gen 4 with 14 lanes, while the Intel chip provides Gen 3 with 9 lanes. Integrated graphics differ: AMD uses the Radeon 840M, Intel uses UHD Graphics 770. Both parts are mobile segments, use sockets that are not interchangeable (AMD Socket FP8 versus Intel BGA 1264), and have locked multipliers, so neither supports overclocking.

Head-to-Head Benchmarks

The largest single win for the AMD Ryzen AI 7 345 comes in PassMark extended instructions, where it scores 17003 against the Intel Core 3 N355’s 5968. This 184.9% delta shows a massive advantage in workloads that use advanced CPU instruction sets, such as AVX or similar extensions. The Intel part’s lower score suggests its Alder Lake-N derived cores are significantly less capable in this area.

Cinebench R23 multicore delivers a 117.8% lead for AMD, with scores of 11461 versus 5262. This test stresses all cores and threads, and the AMD chip’s 12 threads combined with its higher boost clock of 4.60 GHz (versus 3.90 GHz) produce a decisive result. Cinebench R15 multicore shows a similar pattern: 1712 versus 822, a 108.3% delta.

PassMark integer math favors AMD at 63475 versus 33894, an 87.3% advantage. Floating-point math shows 42621 versus 22695, an 87.8% delta. Data compression results are 237484 versus 117435, a 102.2% lead. The AMD chip’s higher memory bandwidth (89.6 GB/s versus 38.4 GB/s) likely contributes to these large margins in data-heavy tests.

PassMark multithread scores 19927 for AMD versus 10174 for Intel, a 95.9% delta. Physics tests show 1089 versus 625, a 74.2% advantage. Random string sorting gives AMD 25435 versus 14706, a 73% lead. Data encryption is the closest test, with AMD at 11814 and Intel at 8121, a 45.5% delta. Prime number finding shows 62 versus 27, a 129.6% gap.

Single-thread tests also favor AMD. Cinebench R15 single-core shows 271 versus 168, a 61.3% delta. Cinebench R23 single-core shows 1818 versus 1039, a 75% lead. PassMark single-thread (recorded as both single_thread and singlethread) shows 3875 versus 2153, an 80% delta. Even in the most efficiency-oriented tests, the Intel part cannot close the gap.

Specification Differences

The two processors differ in nearly every core specification. The AMD Ryzen AI 7 345 has 6 cores and 12 threads, a base clock of 2.00 GHz, and a boost clock of 4.60 GHz. The Intel Core 3 N355 has 8 cores and 8 threads, a base clock of 1.90 GHz, and a boost clock of 3.90 GHz. The AMD part’s boost clock is 0.70 GHz higher, which directly explains its single-thread advantage.

TDP differs: the AMD chip is rated at 28 W, the Intel chip at 15 W. This makes the Intel part more power-efficient on paper, but the performance per watt is not reflected in the benchmark data. The AMD chip’s higher TDP allows it to sustain higher clocks under load.

Process node and foundry differ: AMD uses a 4 nm process at TSMC, Intel uses a 10 nm process at Intel. Cache configurations differ: AMD has 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3. Intel has 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. Despite Intel’s larger L3, AMD’s performance is superior in all tests.

Memory support differs: AMD supports DDR5 and LPDDR5X with dual-channel memory and 89.6 GB/s bandwidth. Intel supports DDR4, DDR5, and LPDDR5 but with single-channel memory and 38.4 GB/s bandwidth. PCIe versions also differ: AMD uses Gen 4 with 14 lanes, Intel uses Gen 3 with 9 lanes. Integrated graphics differ: AMD has Radeon 840M, Intel has UHD Graphics 770.

Sockets are incompatible: AMD uses Socket FP8, Intel uses BGA 1264. Release dates are close, with Intel launching on 2025-01-06 and AMD on 2025-01-14. Both parts are active in production, have no ECC memory support, and have locked multipliers. The AMD part number is 100-000002122, the Intel part number is SRPNT. Neither processor has a recorded launch MSRP in the database.
