Architecture Differences

The two processors come from entirely different Intel design families and manufacturing generations. The Core 3 N350 uses the Twin Lake architecture, part of the Core 3 generation based on Alder Lake-N, and is fabricated on a 10 nm process at Intel's own foundry. The Core Ultra 7 270HX Plus belongs to the Core Ultra Series 2, uses the Arrow Lake-HX Refresh codename from the Ultra 7 generation, and is built on a 3 nm process at TSMC. The Core Ultra 7 270HX Plus integrates 17,800 million transistors on a 243 mm² die; the Core 3 N350 does not have transistor count or die size data recorded in the database.

Core and thread counts differ substantially. The Core 3 N350 provides 8 cores and 8 threads, while the Core Ultra 7 270HX Plus provides 20 cores and 20 threads. Neither processor uses simultaneous multithreading according to the recorded thread counts. The Core Ultra 7 270HX Plus has a base clock of 2.40 GHz and a boost clock of 5.30 GHz.

The Core Ultra 7 270HX Plus has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 30 MB of shared L3 cache. The Core Ultra 7 270HX Plus's per-core L2 allocation is notably larger, which contributes to its higher single-thread scores.

Memory support also differs. The Core 3 N350 supports DDR4, DDR5, and LPDDR5 memory across a single-channel bus with 38.4 GB/s of bandwidth. The Core Ultra 7 270HX Plus supports only DDR5 across a dual-channel bus with 102.4 GB/s of bandwidth. Neither CPU supports ECC memory. PCIe connectivity is another differentiator: the Core 3 N350 offers PCIe Gen 3 with 9 CPU lanes, while the Core Ultra 7 270HX Plus offers PCIe Gen 5 with 20 CPU lanes.

Integrated graphics differ as well. The Core 3 N350 uses UHD Graphics 770, while the Core Ultra 7 270HX Plus uses Arc Xe-LPG Graphics with 64 execution units. The thermal design power is substantially different: the Core 3 N350 is rated at 7 watts, while the Core Ultra 7 270HX Plus is rated at 55 watts. This power envelope difference explains part of the performance gap, as the Core Ultra 7 270HX Plus has far more thermal headroom for sustained high-frequency operation.

The Verdict

The recorded data presents a straightforward hierarchy. The Intel Core Ultra 7 270HX Plus is the dominant processor in every measured workload, with deltas ranging from 58.6 percent in PassMark single-thread to 95.9 percent in PassMark find prime numbers. The Core 3 N350 does not win a single benchmark in the head-to-head comparison. For any application that benefits from multi-core throughput, rendering performance, or sustained compute, the Core Ultra 7 270HX Plus is the clear choice based on the data.

The Core 3 N350's strongest showing relative to the Core Ultra 7 270HX Plus appears in single-threaded PassMark testing, where its 1974 score trails by 58.6 percent rather than the 80 to 90 percent gaps seen in most other tests. This indicates that the Core 3 N350's per-core efficiency is its least disadvantageous attribute, though it still falls far short of the Core Ultra 7 270HX Plus's 4764 score.

The Core Ultra 7 270HX Plus's 93rd percentile ranking among all CPUs in the database places it in the company of desktop flagship-class parts. Its nearest rivals include the Intel Core i9-13900KF, Core i9-13900K, and Core i9-13900T, all with average scores within 0.2 percent of the Core Ultra 7 270HX Plus. The Core 3 N350's 66th percentile ranking places it near the Intel Core i7-3770 and Core i5-1035G1, with the AMD EPYC 7F52 trailing by 2.5 percent.

The power envelope difference is a key consideration in the data. The Core 3 N350 operates at 7 watts TDP versus 55 watts for the Core Ultra 7 270HX Plus. The Core Ultra 7 270HX Plus consumes roughly 8 times the power budget, which aligns with its roughly 6.2 times higher average benchmark score. The Core 3 N350's low power draw and modest performance profile suggest it is designed for power-constrained mobile applications where battery life takes priority over throughput. The Core Ultra 7 270HX Plus's higher power budget buys substantially more performance, particularly in multi-threaded workloads.

For users prioritizing maximum compute capability in a mobile platform, the Core Ultra 7 270HX Plus is the only rational choice based on the benchmark data. For users prioritizing minimal power consumption with acceptable basic performance, the Core 3 N350 offers a much lower TDP at the cost of significantly lower scores across every recorded test.
