Analysis: Intel Core 7 350 vs Intel Core Ultra 7 155UL
Where Each One Wins
The Intel Core 7 350 and the Intel Core Ultra 7 155UL are both 15W parts, but they target different segments of the mobile and desktop market. The recorded data shows a clear split: the Core 7 350 is a mobile processor with a substantial benchmark profile, while the Core Ultra 7 155UL is a desktop-oriented chip with no recorded benchmark scores in the database. This absence of measurements for the Ultra 7 155UL is itself the defining differentiator.
The Core 7 350 wins every measurable category because it is the only one with data. It posts a Cinebench R23 multi-core score of 8030 and a single-core score of 2046. The Ultra 7 155UL has no benchmark entries, meaning no direct comparison can be made from recorded results. In terms of market presence, the Core 7 350 sits in the mobile segment with a 71st percentile ranking among all CPUs, while the Ultra 7 155UL sits in the desktop segment with a 50th percentile ranking. The percentile gap, 71 versus 50, suggests the Core 7 350 outperforms a larger share of the overall CPU pool, but the Ultra 7 155UL's lack of scores means this is not a direct head-to-head result.
For single-threaded work, the Core 7 350 shows a PassMark single-thread score of 4100. For multi-threaded workloads, it delivers a PassMark multi-thread score of 15170. The Ultra 7 155UL offers no such figures. The nearest rivals for the Core 7 350 include the Intel Core 5 221TE with an average score of 17860 and a delta of -0.5%, the AMD EPYC 9374F at 17693 with a delta of 0.5%, and the AMD Ryzen 5 3600XT at 17891 with a delta of -0.6%. These deltas place the Core 7 350 within a tight performance band around those parts, none of which are the Ultra 7 155UL.
The use-case split is therefore defined by the data's absence. The Core 7 350 is the only chip here with measured performance. The Ultra 7 155UL, lacking any recorded scores, cannot claim a win in any benchmark category. The Core 7 350 wins on available evidence alone.
Architecture Differences
The two processors use fundamentally different silicon. The Core 7 350 is built on a 3 nm process node, while the Ultra 7 155UL uses a 7 nm node. Both are manufactured by Intel, but the Core 7 350 belongs to the Wildcat Lake codename family, and the Ultra 7 155UL is a Meteor Lake-PS part under the Meteor Lake architecture. The Core 7 350 is part of the Core 5 generation, specifically the Wildcat Lake variant, while the Ultra 7 155UL is part of the Core Ultra Series 1.
Core counts differ sharply. The Core 7 350 has 6 cores and 6 threads, a configuration with no hyperthreading. The Ultra 7 155UL has 12 cores and 14 threads, indicating a hybrid arrangement with more execution resources. The Ultra 7 155UL's thread count of 14 exceeds its core count of 12, which implies some cores support additional threads. The Core 7 350's thread count equals its core count.
Cache hierarchies also diverge. The Core 7 350 has 192 KB of L1 cache per core, 2.5 MB of L2 per core, and 6 MB of shared L3 cache. The Ultra 7 155UL has 112 KB of L1 per core, 2 MB of L2 per core, and 12 MB of shared L3. The Ultra 7 155UL doubles the L3 capacity, 12 MB versus 6 MB, but has smaller per-core L1 and L2 allocations. This suggests the Ultra 7 155UL relies on a larger shared cache to feed its additional cores.
Memory support differs as well. The Core 7 350 uses DDR5 and LPDDR5X memory with a single-channel bus and 59.7 GB/s of bandwidth. The Ultra 7 155UL uses DDR5 with support that depends on the motherboard, a dual-channel bus, and 89.6 GB/s of bandwidth. The Ultra 7 155UL offers higher memory bandwidth, 89.6 GB/s versus 59.7 GB/s, which aligns with its desktop positioning. The Core 7 350's PCIe implementation is Gen 4 with 6 lanes from the CPU, while the Ultra 7 155UL provides Gen 4 with 8 lanes.
Integrated graphics differ as well. The Core 7 350 uses Intel Xe3 Graphics with 2 Xe cores, while the Ultra 7 155UL uses Arc Xe-LPG with 64 execution units. The sockets are not interchangeable: the Core 7 350 uses Intel BGA 1516, and the Ultra 7 155UL uses Intel Socket 1851. The Core 7 350 is a mobile part, and the Ultra 7 155UL is a desktop part.
Head-to-Head Benchmarks
There are no head-to-head benchmark entries in the database for these two processors. The head-to-head list is empty, and the wins counters show zero for both sides. This means the recorded data contains no direct comparison scores, no per-test deltas, and no victory totals.
The Core 7 350 does have a full benchmark suite. Its Cinebench R15 multi-core score is 1220, and its single-core score is 292. In Cinebench R20, it scores 5373 multi-core and 758 single-core. In Cinebench R23, the multi-core score is 8030, and the single-core score is 2046. PassMark results include data compression at 143123, data encryption at 10933, extended instructions at 12045, prime number finding at 107, floating point math at 42809, integer math at 33734, multi-thread at 15170, physics at 1173, random string sorting at 17238, and single-thread at 4100.
The Ultra 7 155UL has no scores in any of these tests. The database records no Cinebench results, no PassMark results, and no other benchmark entries for it. The average benchmark score for the Ultra 7 155UL is 0, which reflects the absence of data rather than a zeroed performance result.
Comparisons to the Core 7 350's nearest rivals provide context. The Intel Core 5 221TE has an average score of 17860 and trails the Core 7 350 by 0.5%. The AMD EPYC 9374F has an average score of 17693 and leads the Core 7 350 by 0.5%. The AMD Ryzen 5 3600XT scores 17891, which is 0.6% behind the Core 7 350, and the Intel Core 5 120U scores 17898, which is 0.7% behind. The Core 7 350's average benchmark score is 17779, placing it in a narrow band around these competitors. None of these rivals is the Ultra 7 155UL, and the Ultra 7 155UL has no rival list of its own.
The biggest win for the Core 7 350 is therefore the existence of measurable results. Without any recorded data for the Ultra 7 155UL, the Core 7 350 stands as the only processor here with a benchmark profile.

The Verdict
The data strongly favors the Intel Core 7 350 on the basis of measured results. It has a complete benchmark profile, a 71st percentile ranking, and an average benchmark score of 17779. The Ultra 7 155UL has no benchmark scores, a 50th percentile ranking, and an average benchmark score of 0. Any user requiring recorded performance data should choose the Core 7 350.
Architecturally, the Ultra 7 155UL offers more cores, 12 versus 6, more threads, 14 versus 6, and more L3 cache, 12 MB versus 6 MB. It also provides higher memory bandwidth, 89.6 GB/s versus 59.7 GB/s, and a dual-channel bus. These specifications suggest the Ultra 7 155UL has more raw resources for parallel workloads, but the absence of benchmark results prevents any performance confirmation.
The Core 7 350 counters with a 3 nm process node versus 7 nm, a higher single-core clock profile with the same 4.80 GHz boost, and a mobile form factor with LPDDR5X support. Its nearest rivals include the Intel Core 5 221TE, AMD EPYC 9374F, AMD Ryzen 5 3600XT, and Intel Core 5 120U, all within a 0.7% performance band. The Core 7 350's 71st percentile ranking indicates it outperforms a majority of recorded CPUs, while the Ultra 7 155UL's 50th percentile ranking places it at the median, though this is based on no measured scores.
The verdict from the recorded data is straightforward: the Core 7 350 is the only processor with demonstrable performance. The Ultra 7 155UL may have a larger core count and cache pool, but without benchmark entries, its real-world standing cannot be assessed. The Core 7 350 is the pick for anyone relying on database measurements.
