Architecture Differences

The two processors represent distinct architectural approaches within Intel's mobile lineup. The Intel Core 7 350 is built on the Wildcat Lake architecture, while the Intel Core Ultra 7 256V uses the Lunar Lake architecture and belongs to the Core Ultra Series 2. Despite sharing the same 3 nm process node, their physical designs differ substantially.

The core counts are not identical. The Intel Core 7 350 has 6 cores and 6 threads, meaning it does not use simultaneous multithreading. The Intel Core Ultra 7 256V has 8 cores and 8 threads, also without SMT, but provides two additional physical cores for parallel workloads. Both have the same L1 cache structure at 192 KB per core and the same L2 cache at 2.5 MB per core.

The shared L3 cache is a major differentiator. The Intel Core 7 350 has 6 MB of shared L3 cache, while the Intel Core Ultra 7 256V doubles that to 12 MB. This larger cache pool benefits the Ultra part in repeated data access patterns and larger working sets, which the benchmark data partially reflects.

The integrated graphics differ as well. The Intel Core 7 350 uses Intel Xe3 Graphics with 2 Xe cores. The Intel Core Ultra 7 256V uses Arc 140V graphics, a higher-tier solution. The database does not record graphics benchmark scores for either part, so the comparison here is limited to specification presence.

Memory support also diverges. The Intel Core 7 350 officially supports DDR5 and LPDDR5X over a single-channel bus, with a measured bandwidth of 59.7 GB/s. The Intel Core Ultra 7 256V lists memory support as dependent on the motherboard, uses a dual-channel bus, and has no recorded bandwidth figure. The dual-channel configuration gives the Ultra part a structural memory bandwidth advantage, though the exact numeric benefit is not in the recorded data.

PCIe connectivity differs by generation and lane count. The Intel Core 7 350 provides PCIe Gen 4 with 6 CPU-only lanes. The Intel Core Ultra 7 256V provides PCIe Gen 5 with 4 CPU-only lanes. This means the Core 7 350 has more lanes for attached devices, while the Ultra part uses a faster interface standard per lane.

The sockets are incompatible. The Intel Core 7 350 uses Intel BGA 1516, while the Intel Core Ultra 7 256V uses Intel BGA 2833. The production status for both is listed as Active. The Core 7 350 has a launch MSRP of $469 and was released in 2026-04-15, while the Core Ultra 7 256V has no recorded launch MSRP and was released in 2024-09-23.

Head-to-Head Benchmarks

The benchmark record shows a consistent pattern: the Intel Core Ultra 7 256V dominates multi-threaded and compute-heavy workloads, while the Intel Core 7 350 wins narrowly in a few single-threaded tests.

Starting with Cinebench R15, the Ultra part scores 1583.5 in multi-core versus 1220 for the Core 7 350, a 23% deficit for the Core 7 350. In single-core R15, the tables turn slightly: the Core 7 350 scores 292 versus 285.5, a 2.3% edge.

Cinebench R20 shows a larger multi-core gap. The Ultra part scores 6958, and the Core 7 350 scores 5373, a 22.8% difference. The single-core R20 result also favors the Ultra part: 982 versus 758, again a 22.8% gap. This is notable because in R15 single-core the Core 7 350 won, but in R20 single-core the Ultra part wins by a wide margin.

Cinebench R23 repeats the pattern. Multi-core: 10399 for the Ultra part versus 8030 for the Core 7 350, a 22.8% lead. Single-core R23, however, reverses: the Core 7 350 scores 2046 versus 1877.5, a 9% win. This single-core R23 result is the largest win for the Core 7 350 in any Cinebench test.

The PassMark suite reinforces the Ultra part's dominance. In data compression, the Ultra part scores 184985 versus 143123, a 22.6% lead. Data encryption shows 13998 versus 10933, a 21.9% advantage. Extended instructions: 15643 versus 12045, a 23% gap. Integer math: 43358 versus 33734, a 22.2% lead. Floating point math: 58576 versus 42809, a 26.9% gap. Physics: 1595 versus 1173, a 26.5% lead. Random string sorting: 22481 versus 17238, a 23.3% gap. Multithread score: 19530 versus 15170, a 22.3% difference.

The prime numbers test shows the most extreme divergence. The Ultra part scores 192, while the Core 7 350 scores only 107, a 44.3% gap. This workload likely benefits from the additional cores and the larger L3 cache.

The single-threaded PassMark results favor the Core 7 350. It scores 4100 in both passmark_single_thread and passmark_singlethread, while the Ultra part scores 4029 in both. That gives the Core 7 350 a 1.8% edge in each.

The wins tally is 13 for the Ultra part and 4 for the Core 7 350. The Core 7 350's wins are all in single-threaded tests: Cinebench R15 single-core, Cinebench R23 single-core, and the two PassMark single-thread records. The Ultra part wins every multi-threaded test and also wins Cinebench R20 single-core, which is an outlier in the single-thread category.

The two chips share several characteristics: both are mobile segments, 3 nm process node, 192 KB L1 per core, 2.5 MB L2 per core, no ECC support, locked multipliers, and both are Active production. The boost clocks are identical at 4.80 GHz. The base clocks differ, with the Ultra part starting at 2.20 GHz versus 1.50 GHz for the Core 7 350. The TDP difference is small, 17 W versus 15 W.

The Verdict

The benchmark data indicates a clear performance hierarchy. The Intel Core Ultra 7 256V is the stronger processor for almost all recorded workloads. Its average benchmark score of 21112 is roughly 18.7% higher than the Core 7 350's 17779, and its percentile ranking of 75 versus 71 confirms a higher overall standing in the database.

The head-to-head results are decisive. The Ultra part wins 13 of 17 tests, including all multi-threaded tests and the majority of PassMark workloads. The margins are typically in the 22% to 27% range, with a peak of 44.3% in prime number finding. This suggests the 8-core configuration and 12 MB L3 cache provide a meaningful advantage in parallel execution.

The Core 7 350 does not cede every category. It wins Cinebench R23 single-core by 9% and edges out the Ultra part in Cinebench R15 single-core and both PassMark single-thread tests. These wins are narrow, ranging from 1.8% to 9%. The Core 7 350 also carries a higher launch MSRP of $469, while the Ultra part has no recorded launch MSRP, so a price comparison cannot be made from the data.

For a buyer prioritizing single-thread responsiveness in legacy workloads, the Core 7 350 shows a small advantage. For everything else, the Core Ultra 7 256V is the recommended choice based on the recorded scores.

Where Each One Wins

The Intel Core Ultra 7 256V wins in every multi-threaded benchmark category. This includes all three Cinebench multi-core tests (R15, R20, R23), where it leads by 22.8% to 23%. It also wins all PassMark compute tests: data compression, data encryption, extended instructions, find prime numbers, floating point math, integer math, multithread, physics, and random string sorting. The margins range from 21.9% to 44.3%, with most clustering near 22% to 27%. This makes the Ultra part the clear choice for rendering, video encoding, scientific computation, and any workload that scales with core count and cache size.

The Intel Core 7 350 wins in a narrow set of single-threaded conditions. It takes Cinebench R15 single-core by 2.3%, Cinebench R23 single-core by 9%, and both PassMark single-thread tests by 1.8%. These wins are consistent in direction but small in magnitude. The Core 7 350 also wins Cinebench R20 single-core by a wide margin, but that result is contradicted by the head-to-head data, which records the Ultra part winning that specific test by 22.8%. The database records the Core 7 350 as the winner in R20 single-core in its own benchmark list, but the head-to-head comparison shows the opposite. The head-to-head record is the authoritative pairwise result.

For users running older or single-threaded applications, the Core 7 350 offers a modest edge in some tests. For users running modern multi-threaded software, the Core Ultra 7 256V is the stronger part by a substantial margin. The data does not support any workload category where the Core 7 350 leads by more than 9%, while the Ultra part leads by more than 20% in most categories. The overall winner is the Intel Core Ultra 7 256V.
