Intel Core 3 N350 vs Intel Core Ultra 5 225T Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the Intel Core Ultra 5 225T across every benchmark in the comparison. The Core 3 N350 does not win a single test. The most lopsided result appears in PassMark's find prime numbers test, where the Core Ultra 5 225T scores 284 versus just 20 for the Core 3 N350, a gap of 93 percent in favor of the larger chip.

Cinebench results follow the same pattern. In Cinebench R23 multicore, the Core Ultra 5 225T records 21,971 points while the Core 3 N350 manages 6,274 points, a 71.4 percent difference. The single-core variant shows a similar margin: 3,101 points versus 885 points, a 71.5 percent delta. The consistency of this 71 percent gap across all three Cinebench versions (R15, R20, and R23) indicates that the performance difference scales uniformly with the workload, rather than being specific to one benchmark revision.

PassMark integer math narrows the gap somewhat. The Core Ultra 5 225T scores 59,543 against 27,669 for the Core 3 N350, a 53.5 percent difference. Single-thread performance also shows a smaller relative gap: 4,348 versus 1,974, a 54.6 percent delta. These two results suggest that the Core 3 N350's single-core efficiency is comparatively less disadvantaged than its multicore throughput, although still far behind.

The widest performance chasm outside of prime numbers appears in extended instructions, where the Core Ultra 5 225T scores 20,083 and the Core 3 N350 scores 3,981, an 80.2 percent difference. Floating point math shows a 78.5 percent gap (82,751 versus 17,781), and physics follows at 78.3 percent (2,053 versus 446). Data encryption shows a 68.9 percent delta (18,289 versus 5,693), while data compression is closer at 65.6 percent (233,998 versus 80,444). Random string sorting shows a 64.9 percent difference (28,774 versus 10,102). Multithread performance arrives at 25,358 versus 7,382, a 70.9 percent gap.

The average benchmark score places the Core Ultra 5 225T at 30,468, which puts it in the 82nd percentile of all CPUs in the database. The Core 3 N350's average score is 9,903, placing it in the 66th percentile. The nearest rivals for the Core Ultra 5 225T include the Intel Core i9-11980HK (30,422 average, 0.2 percent lower), the AMD Ryzen 5 7640HS (30,390, 0.3 percent lower), the Intel Core i5-13600H (30,548, 0.3 percent higher), and the AMD Ryzen 7 7736U (30,364, 0.3 percent lower). The Core 3 N350's nearest rivals include the Intel Core i7-3770 (9,706, 2 percent lower), the Intel Core i5-1035G1 (9,684, 2.3 percent lower), the AMD EPYC 7F52 (10,159, 2.5 percent higher), and the Intel Xeon Platinum 8280 (10,230, 3.2 percent higher). This places the Core 3 N350 in the company of older desktop and mobile parts, while the Core Ultra 5 225T trades blows with modern high-end mobile processors.

The Verdict

The data points to a straightforward distinction. The Intel Core Ultra 5 225T is the superior processor in every measured dimension, with a 71.5 percent advantage in Cinebench single-core workloads and a 71.4 percent advantage in multicore Cinebench tests. Its average benchmark score of 30,468 is more than three times the Core 3 N350's 9,903. The percentile ranking reinforces this: 82nd versus 66th.

The Core 3 N350 belongs in scenarios where its 7-watt thermal design power and mobile market segment matter more than raw throughput. It is an 8-core, 8-thread Twin Lake part built for low-power mobile devices, and its benchmark profile aligns with that positioning. The Core Ultra 5 225T, by contrast, is a desktop Arrow Lake-S part with a 65-watt TDP, 10 cores, and 10 threads, and it delivers performance that rivals the Intel Core i9-11980HK and the AMD Ryzen 5 7640HS.

For workloads dominated by single-threaded responsiveness, the Core Ultra 5 225T's 3,101 Cinebench R23 single-core score versus 885 for the Core 3 N350 makes the choice unambiguous. For heavily threaded rendering or physics simulation, the multicore results are equally decisive. The Core 3 N350 only makes sense where power constraints and the mobile form factor are the primary considerations, since the benchmark data shows no workload category where it gains ground.

Specification Differences

The two processors differ across nearly every physical and electrical specification. The Core 3 N350 uses 8 cores and 8 threads, while the Core Ultra 5 225T uses 10 cores and 10 threads. The base clock of the Core 3 N350 is 0.10 GHz, and the Core Ultra 5 225T runs at 2.50 GHz. Boost clocks are 3.90 GHz and 4.90 GHz respectively.

Thermal design power presents a major divergence: 7 watts for the Core 3 N350 versus 65 watts for the Core Ultra 5 225T. The Core 3 N350 uses an Intel BGA 1264 socket, while the Core Ultra 5 225T uses Intel Socket 1851. The Core 3 N350 is a mobile part; the Core Ultra 5 225T is a desktop part.

Memory support differs as well. The Core 3 N350 supports DDR4, DDR5, and LPDDR5 with a single-channel memory bus and 38.4 GB/s bandwidth. The Core Ultra 5 225T supports only DDR5, but uses a dual-channel bus with 102.4 GB/s bandwidth. PCIe connectivity moves from Gen 3 with 9 lanes on the Core 3 N350 to Gen 5 with 20 lanes on the Core Ultra 5 225T. Neither processor supports ECC memory, and neither has an unlocked multiplier. The Core 3 N350 part number is SRPNS; the Core Ultra 5 225T part number is listed as unknown. Both processors are active in production status.

Architecture Differences

The Core 3 N350 is built on Intel's Twin Lake architecture and belongs to the Core 3 generation based on Alder Lake-N. It uses a 10 nm process node fabricated by Intel. The Core Ultra 5 225T uses Arrow Lake architecture, specifically the Arrow Lake-S die, and belongs to the Core Ultra Series 2. It is fabricated by TSMC on a 3 nm process node and contains 17,800 million transistors on a 243 mm² die.

Cache hierarchies differ substantially. The Core 3 N350 has 96 KB of L1 cache per core, 2 MB of shared L2 cache, and 6 MB of shared L3 cache. The Core Ultra 5 225T has 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3 cache. The L2 cache organization alone changes the memory latency profile, since the Core Ultra 5 225T allocates L2 per core rather than sharing it across all cores.

Integrated graphics also differ. The Core 3 N350 uses UHD Graphics 770, while the Core Ultra 5 225T uses Arc Xe-LPG Graphics 16EU. The release dates are close: the Core 3 N350 launched on 2025-01-06 and the Core Ultra 5 225T launched on 2024-12-31. The Core 3 N350 has no transistor count or die size listed in the database.

Where Each One Wins

The Intel Core Ultra 5 225T wins every benchmark category in the recorded data. It dominates Cinebench rendering workloads, PassMark encryption and compression, extended instruction throughput, floating point math, integer math, physics simulation, random string sorting, and single-thread tests. Its largest advantages are in prime number finding (93 percent), extended instructions (80.2 percent), floating point math (78.5 percent), and physics (78.3 percent). Its smallest advantages are in integer math (53.5 percent) and single-thread (54.6 percent), but even those are commanding.

The Intel Core 3 N350 does not win any benchmark, so its use case comes from outside the benchmark suite. Its 7-watt TDP and mobile market segment make it suitable for fanless or passively cooled designs, and its support for DDR4 alongside DDR5 and LPDDR5 offers memory flexibility that the Core Ultra 5 225T lacks. The single-channel memory bus and Gen 3 PCIe lanes limit its throughput in memory-intensive and expansion-heavy workloads, but for basic mobile computing tasks, its 66th percentile ranking shows it keeps pace with older desktop parts like the Intel Core i7-3770.

The Core Ultra 5 225T, by contrast, is for desktop builds where the 65-watt TDP is acceptable. Its dual-channel memory bus provides 102.4 GB/s of bandwidth, and its Gen 5 PCIe with 20 lanes supports high-speed storage and graphics. The 82nd percentile ranking means it sits among the top tier of CPUs in the database, adjacent to the Intel Core i9-11980HK and the AMD Ryzen 5 7640HS. For any workload measured in the database, the Core Ultra 5 225T is the only choice; the Core 3 N350 should be selected only when power draw, socket type, or memory compatibility takes precedence over raw performance.
