The memory bus configuration also differs: the Core 7 350 uses a single-channel interface, while the Core Ultra 5 338H uses dual-channel. This translates to a measured memory bandwidth of 59.7 GB/s for the Core 7 350 versus 136.5 GB/s for the Core Ultra 5 338H.

PCIe connectivity varies between the two. The Core 7 350 provides Gen 4 with 6 lanes (CPU only), while the Core Ultra 5 338H provides Gen 5 with 4 lanes (CPU only). The integrated graphics solutions are also distinct: the Core 7 350 uses Intel Xe3 Graphics with 2 Xe cores, and the Core Ultra 5 338H uses Arc B370.

Both processors are mobile market segments, are currently in active production, and do not have an unlocked multiplier. They use different sockets: the Core 7 350 uses Intel BGA 1516, and the Core Ultra 5 338H uses Intel BGA 2540. Neither supports ECC memory.

The Verdict

The recorded data shows a clear performance hierarchy. The Intel Core Ultra 5 338H wins 16 of the 17 head-to-head benchmark comparisons, while the Intel Core 7 350 wins only one. The average benchmark score of the Core Ultra 5 338H is 33989, which is nearly double that of the Core 7 350 at 17779.

For multi-threaded workloads, the Core Ultra 5 338H is the decisive choice. Its 12 cores and 18 MB of L3 cache, combined with dual-channel memory, deliver substantial advantages across Cinebench and PassMark tests. The Core 7 350, with 6 cores and 6 MB of L3 cache, falls behind by roughly half in most multi-core scenarios.

For single-threaded tasks, the two processors are closely matched. The Core 7 350 actually wins the Cinebench R23 single-core test by a margin of 0.1%, scoring 2046 versus 2044. The PassMark single-thread test shows the Core Ultra 5 338H ahead by 1.9% (4180 versus 4100). This indicates that per-core performance is similar, with the Core 7 350 having a slight edge in one specific test.

The Core Ultra 5 338H is the appropriate choice for users who need maximum multi-core throughput, higher memory bandwidth, and larger cache capacity. The Core 7 350 is a more modest option that offers competitive single-core performance and a lower TDP of 15 watts versus 25 watts, which may matter for power-constrained mobile designs.

The Core Ultra 5 338H also holds a higher percentile ranking at 84 versus 71, and its nearest rivals include the Intel Core Ultra 7 165H and Intel Core i7-12800HX, indicating it competes at a higher tier. The Core 7 350's nearest rivals include the AMD Ryzen 5 3600XT and Intel Core 5 120U, placing it in a lower performance class.
