Where Each One Wins

The Core Ultra 7 258V wins across the breadth of multi-threaded and compute-heavy workloads. Cinebench multi-core tests, Passmark physics, floating point math, integer math, data compression, encryption, extended instructions, prime number finding, multithread, and random string sorting all go to the Ultra 7 258V. The margins range from 18.2% to 42.2%, with most falling in the 19% to 25% band. This makes the Ultra 7 258V the stronger choice for rendering, scientific computation, compression workloads, and any task that can use more than a couple of threads.

The Core 7 350 wins in four tests: cinebench_r15_singlecore, cinebench_r23_singlecore, passmark_single_thread, and passmark_singlethread. The last two are duplicates of the same measurement, both showing 4100 versus 4018. The Core 7 350's margins are much smaller than the Ultra 7 258V's margins. The largest single-core win is 9.3% in cinebench_r23_singlecore; the other three wins are 2.5%, 2%, and 2%. In single-threaded legacy workloads, the Core 7 350 holds a modest but consistent edge, with the exception of cinebench_r20_singlecore where the Ultra 7 258V wins by a wide 20.3%.

For users focused on lightly threaded applications, the Core 7 350 offers a slight advantage in most single-core measurements. For users whose workloads scale across cores, the Ultra 7 258V is clearly faster in every multi-core test in the dataset. The single-core wins for the Core 7 350 do not offset the multi-core losses in terms of raw score differences. The largest single-core gap in favor of the Core 7 350 is 174 points in cinebench_r23_singlecore (2046 versus 1872), while the largest multi-core gap in favor of the Ultra 7 258V is 2271 points in cinebench_r23_multicore (10301 versus 8030).

Architecture Differences

The two processors come from different Intel design families. The Core 7 350 uses the Wildcat Lake codename and is listed under the Core 5 (Wildcat Lake) generation. The Core Ultra 7 258V belongs to the Core Ultra Series 2, with the Lunar Lake codename and architecture. Both are built on a 3 nm process node, but the foundries differ: Intel fabricates the Core 7 350, while TSMC fabricates the Core Ultra 7 258V.

Core counts differ. The Core 7 350 has 6 cores and 6 threads, while the Core Ultra 7 258V has 8 cores and 8 threads. Neither processor uses simultaneous multithreading, so threads equal cores in both cases. The base clock of the Core 7 350 is 1.50 GHz, while the Core Ultra 7 258V runs at 2.20 GHz. Both boost to 4.80 GHz. The Core 7 350 has a 15 W TDP, and the Core Ultra 7 258V has a 17 W TDP.

Cache configurations share some traits but diverge in L3. Both have 192 KB of L1 per core and 2.5 MB of L2 per core. The shared L3 cache differs: the Core 7 350 has 6 MB, while the Core Ultra 7 258V has 12 MB, exactly double. This larger L3 cache likely contributes to the Ultra 7 258V's advantage in data-heavy workloads.

Memory support also differs. The Core 7 350 supports DDR5 and LPDDR5X over a single-channel memory bus, with 59.7 GB/s of memory bandwidth. The Core Ultra 7 258V supports LPDDR5X only, over a dual-channel bus, with 136.5 GB/s of memory bandwidth. That is more than double the bandwidth of the Core 7 350. The memory bus difference is significant: single-channel versus dual-channel explains part of the performance gap in memory-sensitive benchmarks like prime number finding and compression.

PCIe connectivity differs as well. The Core 7 350 provides Gen 4 with 6 lanes (CPU only), while the Core Ultra 7 258V provides Gen 5 with 4 lanes (CPU only). Integrated graphics differ: the Core 7 350 uses Intel Xe3 Graphics with 2 Xe cores, while the Core Ultra 7 258V uses Arc 140V. Neither processor supports ECC memory, and neither has an unlocked multiplier.

Sockets and release dates separate the two platforms. The Core 7 350 uses Intel BGA 1516 and was released on 2026-04-15. The Core Ultra 7 258V uses Intel BGA 2833 and was released on 2024-09-23. The Core 7 350 has a launch MSRP of $469; the Core Ultra 7 258V has no recorded launch MSRP in the database. Both are marked as Active in production status and target the mobile market segment.

The Verdict

The recorded data indicates that the Intel Core Ultra 7 258V is the faster processor in the majority of benchmark scenarios. It wins 13 of 17 head-to-head comparisons, holds a higher average benchmark score (20454 versus 17779), and sits at a higher percentile (74th versus 71st). Its multi-core advantage is consistent across Cinebench and Passmark workloads, with margins typically between 18% and 25%. The largest gap, 42.2% in prime number finding, shows that the Ultra 7 258V is particularly strong in workloads that combine high thread counts with memory bandwidth.

The Intel Core 7 350 wins four comparisons, all in single-threaded tests, with margins between 2% and 9.3%. These wins are real but narrow. The Core 7 350 also has a lower TDP (15 W versus 17 W) and a lower base clock (1.50 GHz versus 2.20 GHz), yet it still manages to edge ahead in most single-core measurements, with the notable exception of cinebench_r20_singlecore where it loses by 20.3%.

The architecture differences explain much of the performance split. The Ultra 7 258V has two additional cores, double the L3 cache (12 MB versus 6 MB), dual-channel memory with 136.5 GB/s of bandwidth versus 59.7 GB/s, and a higher base clock. The Core 7 350 counters with a higher boost clock in some scenarios and a different graphics solution, but the benchmark data does not show those factors overcoming the Ultra 7 258V's structural advantages.

For workloads that use multiple threads, the Core Ultra 7 258V is the clear choice based on the data. For workloads that are strictly single-threaded and legacy, the Core 7 350 holds a slight edge in most recorded tests. The Core 7 350's wins are concentrated in single-core Cinebench and Passmark, while the Ultra 7 258V wins across every multi-core category in the dataset.
