Intel Core 7 251TE vs Intel Core Ultra 7 258V Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the Intel Core 7 251TE, which wins 14 of the 17 head-to-head comparisons against the Intel Core Ultra 7 258V. The largest margin comes in PassMark integer math, where the 251TE scores 125739 against 42889, a 193.2% advantage. That result reflects a processor with far more physical resources available for sustained compute. Cinebench R23 multi-core shows the same trend on a larger scale: the 251TE posts 25518 versus 10301, a 147.7% lead. These two figures alone establish the 251TE as the clear choice for heavily threaded workloads.

The 251TE also wins every Cinebench test in the dataset. In Cinebench R15 multi-core it scores 2572 against 1596.5, a 61.1% margin. Single-core R15 goes to the 251TE by 27%, with 362 versus 285. Cinebench R20 repeats the pattern: the 251TE leads by 59% in both multi-core (10717 versus 6739) and single-core (1512 versus 951). Cinebench R23 single-core shows a 92.4% gap, with 3602 versus 1872. These results indicate that the 251TE delivers substantially higher per-thread performance in the Cinebench suite, not just a raw core-count advantage.

PassMark tests reinforce the same hierarchy. Data compression favors the 251TE by 89.3% (334399 versus 176686). Data encryption goes to the 251TE by 63.9% (22176 versus 13534). Floating point math shows a 49.2% lead for the 251TE (85607 versus 57372). The multithread score favors the 251TE by 59% (30022 versus 18887), and random string sorting shows an 83.7% gap (39643 versus 21580). Even extended instructions, the closest PassMark result, still favors the 251TE by 15.3% (16974 versus 14717). Physics simulation also goes to the 251TE, with a 23.8% margin (1938 versus 1565).

The Core Ultra 7 258V wins only three comparisons, all in PassMark. Its single-thread score of 4018 beats the 251TE's 3568, an 11.2% advantage. That is its strongest result and appears twice in the dataset under both PassMark single-thread naming conventions. The 258V also wins the find prime numbers test, scoring 185 against 140, a 24.3% edge for the Ultra part. These wins are narrow in scope but consistent: the 258V shows better lightweight single-thread throughput in PassMark, while the 251TE dominates everywhere else.

The average benchmark score tells the same story from a different angle. The 251TE averages 41650 across its benchmark set, placing it in the 88th percentile of all CPUs in the database. The 258V averages 20454, which puts it in the 74th percentile. That is a roughly twofold gap in average score, consistent with the head-to-head deltas. The 251TE's nearest rivals in the database are the Intel Core Ultra 7 265H (delta 0.1%), the Intel Core i7-14650HX (delta 0.2%), the Intel Core i7-12850HX (delta -0.3%), and the Intel Core i7-14700T (delta -0.6%). All four sit within a fraction of a percent, meaning the 251TE is positioned in a competitive desktop-class band. The 258V's nearest rivals are the AMD Ryzen 5 5600 (delta -0.1%), the AMD Ryzen 5 8500G (delta 0.1%), the AMD EPYC 9454P (delta 0.2%), and the AMD EPYC 7713 (delta 0.4%). Those rivals span desktop and server parts, reflecting the 258V's mid-range placement.

Architecture Differences

The two processors come from different Intel design lines. The Intel Core 7 251TE uses the Bartlett Lake codename and belongs to the Core 7 (Bartlett Lake) generation. It is built on a 10 nm process at Intel's own foundry. The die size is recorded at 215 mm². The Intel Core Ultra 7 258V uses the Lunar Lake architecture and belongs to the Core Ultra Series 2 family. It is built on a 3 nm process at TSMC. The process node difference is substantial: 10 nm versus 3 nm, and the foundries differ as well.

Core counts diverge sharply. The 251TE has 24 cores and 32 threads. The 258V has 8 cores and 8 threads. That is a 16-core and 24-thread difference in favor of the 251TE. Cache layouts also differ. The 251TE carries 80 KB of L1 per core, 1.25 MB of L2 per core, and 36 MB of shared L3. The 258V carries 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3. Per-core cache is larger on the 258V, but total L3 is three times larger on the 251TE.

Memory support separates the two as well. The 251TE supports DDR4 and DDR5 memory over a dual-channel bus, with a recorded memory bandwidth of 89.6 GB/s. The 258V supports LPDDR5X over a dual-channel bus, with a recorded memory bandwidth of 136.5 GB/s. The 258V has the higher bandwidth figure, while the 251TE has broader memory compatibility. The 251TE also supports ECC memory; the 258V does not.

PCIe connectivity differs. The 251TE provides Gen 5 with 16 lanes from the CPU. The 258V provides Gen 5 with 4 lanes from the CPU. Integrated graphics also differ: the 251TE uses UHD Graphics 770, while the 258V uses Arc 140V. Clock speeds go in opposite directions depending on the metric. The 251TE has a base clock of 1.40 GHz and a boost clock of 5.40 GHz. The 258V has a base clock of 2.20 GHz and a boost clock of 4.80 GHz. The 258V starts higher but boosts lower.

Thermal and platform characteristics differ as well. The 251TE has a TDP of 45 watts and uses Intel Socket 1700. The 258V has a TDP of 17 watts and uses Intel BGA 2833. The 251TE is classified as a desktop part, while the 258V is classified as mobile. Both are active production parts and both have locked multipliers. The 251TE was released on 2025-01-12; the 258V was released on 2024-09-23.

The Verdict

The data points to a clear split by workload class. The Intel Core 7 251TE is the stronger processor for multi-threaded and most single-threaded tasks. Its 24 cores and 32 threads drive a 147.7% lead in Cinebench R23 multi-core and a 193.2% lead in PassMark integer math. Across the entire Cinebench suite, the 251TE wins every test, including single-core, by margins from 27% to 92.4%. The 251TE also wins 14 of 17 total comparisons, holds an 88th percentile rank, and averages 41650 in the database.

The Intel Core Ultra 7 258V is the stronger processor for two specific PassMark workloads: single-thread and prime number finding. It wins those by 11.2% and 24.3% respectively. It also carries a higher memory bandwidth figure at 136.5 GB/s and a much lower TDP at 17 watts, but the benchmark data does not show those advantages converting into broader performance wins. The 258V averages 20454 and sits in the 74th percentile, roughly half the average score of the 251TE.

For users prioritizing raw compute throughput across Cinebench and PassMark workloads, the 251TE is the clear choice from the recorded data. For users who need a mobile-class part with lower power draw and better PassMark single-thread throughput, the 258V has a defined but narrow role. The benchmark results do not support the 258V as a general performance equal; they support it as a specialist for lightweight single-thread tasks.

Where Each One Wins

The Intel Core 7 251TE wins in every multi-threaded category recorded. Cinebench R15, R20, and R23 multi-core all favor it, with deltas of 61.1%, 59%, and 147.7% respectively. PassMark multithread follows at 59%. The 251TE also wins data compression by 89.3%, data encryption by 63.9%, floating point math by 49.2%, integer math by 193.2%, random string sorting by 83.7%, extended instructions by 15.3%, and physics by 23.8%. In Cinebench single-core tests, the 251TE also leads, with margins of 27% in R15, 59% in R20, and 92.4% in R23. Any workload that scales with core count or with sustained Cinebench-style throughput belongs to the 251TE.

The Intel Core Ultra 7 258V wins in PassMark single-thread and PassMark find prime numbers. The single-thread score of 4018 beats the 251TE's 3568 by 11.2%. The find prime numbers score of 185 beats the 251TE's 140 by 24.3%. These are the only recorded benchmark victories for the 258V. They indicate a niche for tasks that rely on lightweight, per-thread PassMark-style execution rather than broad multi-core scaling. The 258V also holds advantages in non-benchmark specifications: higher memory bandwidth at 136.5 GB/s, a lower TDP at 17 watts, and a smaller 3 nm process node, but those attributes do not translate into wins in the recorded compute tests beyond the two PassMark cases.
