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

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for the Intel Core 7 251E and the Intel Core Ultra 7 258V. All recorded performance measurements for the Core Ultra 7 258V come from its individual benchmark suite, while the Core 7 251E has no benchmark entries in the database. This absence of comparable test data means any performance relationship between the two processors must be inferred from their recorded specifications and the Core Ultra 7 258V's standalone scores.

The Core Ultra 7 258V delivers a Cinebench R23 multi-core score of 10301 and a single-core score of 1872. In Geekbench, it records 9325 multi-core and 2100 single-core. PassMark results show 18887 for multithread, 4018 for single thread, 42889 for integer math, and 57372 for floating point math. The Core 7 251E has no equivalent scores in the database, so no percentage gains or deficits can be calculated between the two.

The Core Ultra 7 258V's average benchmark score stands at 20454, placing it in the 74th percentile of all CPUs in the database. Its nearest recorded rivals provide context for this score. The AMD Ryzen 5 5600 scores 20468, a delta of -0.1 percent relative to the Core Ultra 7 258V. The AMD Ryzen 5 8500G scores 20425, a delta of 0.1 percent. The AMD EPYC 9454P scores 20422, a delta of 0.2 percent. The AMD EPYC 7713 scores 20363, a delta of 0.4 percent. These deltas indicate the Core Ultra 7 258V sits within a narrow performance band, essentially level with these four rivals, all within 0.4 percent of its average score.

The Core 7 251E holds a 50th percentile ranking among all CPUs, with an average benchmark score of 0. Its percentile placement is based on its specification profile rather than measured results. The Core Ultra 7 258V's 74th percentile places it well above the Core 7 251E's 50th percentile in the database's overall ranking.

Without head-to-head measurements, the only quantitative comparison available is the percentile gap. The Core Ultra 7 258V ranks 24 percentile points higher than the Core 7 251E. That gap reflects the database's evaluation of the Core Ultra 7 258V as the stronger performer relative to all tracked CPUs, but it does not translate into a specific score advantage over the Core 7 251E.

The Core Ultra 7 258V's individual benchmark scores show a processor capable of strong single-threaded work. Its Cinebench R15 single-core score of 285, R20 single-core of 951, and R23 single-core of 1872 form a consistent progression. Its PassMark single-thread score of 4018 reinforces this pattern. Multi-threaded results follow a similar arc: R15 multi-core at 1596.5, R20 multi-core at 6739, and R23 multi-core at 10301.

The Core 7 251E offers no such recorded data. Its 24 cores and 32 threads suggest a high multi-threaded ceiling, but the database has no measurements to confirm it. The Core Ultra 7 258V's 8 cores and 8 threads produce the scores above, and those scores place it in the 74th percentile. The Core 7 251E's 50th percentile with no average score leaves its actual performance unquantified.

The Verdict

The data supports a clear split. The Intel Core Ultra 7 258V is the only one of the two with recorded benchmark results, and those results establish it as a mid-pack performer with a 74th percentile ranking. Its average score of 20454 places it within 0.4 percent of several AMD rivals, including the Ryzen 5 5600, Ryzen 5 8500G, EPYC 9454P, and EPYC 7713. Anyone selecting between these two processors should note that the Core 7 251E's 50th percentile and absent benchmark data offer no measured evidence of its performance.
