Intel Core Ultra X7 358H vs Intel Processor U301L Comparison

The Verdict

The Intel Core Ultra X7 358H is the clear performance leader in this comparison. The recorded data shows it scoring in the 87th percentile among all CPUs, while the Intel Processor U301L sits at the 50th percentile. The Ultra X7 358H delivers 16 cores and 16 threads, compared to 5 cores and 6 threads on the U301L, and the benchmark results confirm a massive gap in both multi-threaded and single-threaded workloads.

The Ultra X7 358H is the choice for anyone running heavy multi-threaded tasks like video encoding, 3D rendering, or software compilation. Its Cinebench R23 multi-core score of 18,747 points indicates strong sustained throughput. The U301L, with no recorded benchmark scores in the database, cannot match this level of performance, and its lower core count and clock speeds place it firmly in the entry-level segment.

The U301L does have one clear advantage: power consumption. Its 15 W TDP is significantly lower than the 25 W TDP of the Ultra X7 358H. For fanless or ultra-low-power designs where absolute performance is secondary, the U301L fits that role. However, the data shows no scenario where the U301L wins on raw performance.

Architecture Differences

The two processors come from different design eras and process nodes. The Intel Core Ultra X7 358H uses the Panther Lake codename, built on a 3 nm process, and belongs to the Core Ultra Series 3 generation. The Intel Processor U301L uses Raptor Lake architecture, built on a 10 nm process, and belongs to the Intel Processor (Raptor Lake) generation.

The core configuration differs substantially. The Ultra X7 358H has 16 cores and 16 threads, while the U301L has 5 cores and 6 threads. This means the Ultra X7 358H has no hyperthreading, as core count equals thread count, while the U301L gains one extra thread from its 5 cores. The cache hierarchy also differs: the Ultra X7 358H has 192 KB L1 per core, 3 MB L2 per core, and 18 MB shared L3, whereas the U301L has 80 KB L1 per core, 1.25 MB L2 per core, and 8 MB shared L3.

Clock speeds are another major divider. The Ultra X7 358H runs at a 1.90 GHz base clock and boosts to 4.80 GHz. The U301L runs at a 1.20 GHz base clock and boosts to 2.20 GHz. The boost differential alone, 4.80 GHz versus 2.20 GHz, explains much of the single-thread performance gap.

Memory support also separates the two. The Ultra X7 358H supports LPDDR5X memory with dual-channel configuration and 153.6 GB/s bandwidth. The U301L supports DDR4 and DDR5 memory in dual-channel configuration, but the database lists no memory bandwidth figure. Neither processor supports ECC memory.

The integrated graphics differ as well. The Ultra X7 358H carries Arc B390 graphics, while the U301L uses UHD Graphics 64EU. PCIe support also differs: the Ultra X7 358H provides Gen 5 with 4 CPU lanes, and the U301L provides Gen 4 with 8 CPU lanes.

The Ultra X7 358H uses the Intel BGA 2540 socket, while the U301L uses Intel Socket 1700. Both are mobile market segment parts, both are in active production, and both have locked multipliers. The Ultra X7 358H was released in January 2026, while the U301L was released in April 2024.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two processors. The Ultra X7 358H has a full suite of recorded benchmark scores, while the U301L has zero recorded benchmarks. This absence of data for the U301L means comparisons must rely on the Ultra X7 358H's absolute scores and its percentile standing.

The Ultra X7 358H's Cinebench scores show its capability. In Cinebench R15, it scores 3,027 multi-core and 301.5 single-core. In Cinebench R20, it scores 12,011 multi-core and 1,695 single-core. In Cinebench R23, it scores 18,747 multi-core and 2,080 single-core. These numbers indicate a processor that scales well with thread count, as the multi-core scores are roughly 9 to 10 times the single-core scores, consistent with a 16-core design.

PassMark results reinforce this picture. The multi-thread score is 33,802, while the single-thread score is 4,124. Integer math scores 83,147, floating point math scores 103,842, and extended instructions scores 27,274. Data compression scores 332,508, and data encryption scores 26,046. Physics scores 3,021, random string sorting scores 40,357, and find prime numbers scores 337.

The average benchmark score for the Ultra X7 358H is 40,967. Its nearest rivals in the database include the AMD Ryzen AI 5 PRO 440 with an average score of 41,208 and a delta of -0.6%, the Intel Core Ultra 7 356H with 41,215 and -0.6%, the AMD Ryzen AI 5 PRO 435G with 40,718 and +0.6%, and the Intel Core Ultra 7 366H with 41,263 and -0.7%. The Ultra X7 358H sits essentially level with these parts, within roughly a percentage point in either direction.

The U301L has no such data. Its average benchmark score is listed as 0, and it has no nearest rivals recorded. The database cannot show any benchmark where the U301L outpaces the Ultra X7 358H, because no U301L results exist.

The core count difference is the most consequential specification gap. The Ultra X7 358H has more than three times the cores of the U301L. The clock speed gap is also large, with the Ultra X7 358H boosting to more than double the U301L's boost clock. The cache allocation favors the Ultra X7 358H in both per-core and shared capacities. The process node advantage, 3 nm versus 10 nm, explains how the Ultra X7 358H delivers far more performance within a modest TDP increase from 15 W to 25 W.

The PCIe configuration differs in an interesting way: the U301L offers 8 Gen 4 lanes, while the Ultra X7 358H offers only 4 Gen 5 lanes. The Gen 5 lanes on the Ultra X7 358H carry more bandwidth per lane, but the U301L has more total lanes.

Where Each One Wins

The Intel Core Ultra X7 358H wins in every performance category with recorded data. Its 16 cores and 4.80 GHz boost clock make it the pick for multi-threaded rendering, video encoding, and any workload that scales across cores. The Cinebench R23 multi-core score of 18,747 and PassMark multi-thread score of 33,802 confirm this. Its 87th percentile ranking places it among capable mobile processors, essentially tied with the AMD Ryzen AI 5 PRO 440 and Intel Core Ultra 7 356H.

The Intel Processor U301L wins on power efficiency and platform cost. Its 15 W TDP is 10 W lower than the Ultra X7 358H, making it the better fit for passively cooled or battery-critical designs. Its launch MSRP of $107, stated once here, also positions it as a lower-cost entry point, though the database does not list a price for the Ultra X7 358H. The U301L additionally offers 8 PCIe Gen 4 lanes, which may suit systems needing more total expansion lanes rather than the 4 Gen 5 lanes of the Ultra X7 358H.

For users who need a compact, low-power mobile processor for basic tasks, the U301L delivers the necessary essentials at reduced power. For users who need serious compute throughput, the Ultra X7 358H is the only one of the two with any recorded performance data, and that data is strong. The choice comes down to power budget versus compute demand, and the recorded benchmarks leave no ambiguity about which part is faster.
