Intel Core 5 120 vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The recorded database currently contains no head-to-head benchmark entries between the Intel Core 5 120 and the Intel Core 7 251E. The head-to-head section lists zero wins for either part, and the Core 7 251E has no benchmark scores populated at all. This makes a direct numerical comparison impossible from the measured data available.

What can be analyzed is the Intel Core 5 120's position within the broader database. Its Cinebench R23 multicore score sits at 18255, with a single-core score of 2577. In Cinebench R20, the multicore result is 7667 and single-core is 1082. The older Cinebench R15 tests show 1840 multicore and 259 single-core. PassMark results for the Core 5 120 include a multithread score of 18597, a single-thread score of 3595, integer math at 60462, floating point math at 45383, data compression at 219535, data encryption at 11131, extended instructions at 14264, find prime numbers at 77, physics at 1333, and random string sorting at 21499.

The Core 5 120 holds a 77th percentile ranking among all CPUs tested in the database. Its average benchmark score is 25362. The nearest rivals in the database provide context: the AMD Ryzen 5 5600X3D averages 25365, which is a 0 percent delta, effectively a tie. The Intel Core i7-11700KF averages 25423, placing the Core 5 120 at 0.2 percent behind. The Intel Core i5-13400F averages 25292, with the Core 5 120 0.3 percent ahead. The AMD Ryzen 7 7840U averages 25432, leaving the Core 5 120 0.3 percent behind.

For the Core 7 251E, the database records no benchmark scores, no nearest rivals, and an average score of 0. Its percentile ranking is 50, but this figure is not supported by any measured data in the current records. The Core 5 120 therefore has a complete benchmark profile, while the Core 7 251E has none.

The Verdict

Benchmark results indicate that the Intel Core 5 120 delivers a fully measured performance profile, landing in the 77th percentile of all CPUs. Its average score of 25362 places it within a tight cluster of rivals, all within 0.3 percent of each other. The data shows no single dominant win for the Core 5 120 against any of its nearest rivals, as the deltas are essentially noise-level.

The Intel Core 7 251E cannot be positioned in any performance ranking from the recorded data. Since the database contains no benchmark entries for this processor, any claim about its relative speed would be unsupported. The 50th percentile figure appears in the records, but with an average score of 0 and no rival comparisons, this percentile lacks the backing of actual test results.

From the data alone, the Core 5 120 is the only part with a verifiable performance footprint. Users who require measured benchmark evidence should rely on the Core 5 120's results. The Core 7 251E's specifications suggest a very different part, but the database does not confirm how it performs.

Where Each One Wins

The Core 5 120 wins in the only category where data exists: measured benchmarks. It has 16 recorded test results across Cinebench and PassMark suites, covering multicore, single-core, math, encryption, compression, and sorting workloads. Its scores show balanced performance across integer math (60462), floating point math (45383), and data compression (219535) in PassMark tests.

The Core 7 251E has no recorded wins because it has no recorded scores. Its specification sheet indicates a larger configuration, with 24 cores and 32 threads versus the Core 5 120's 6 cores and 12 threads. The cache hierarchy differs substantially, with the Core 7 251E featuring 36 MB of shared L3 cache and 2 MB of L2 per core, compared to 18 MB of L3 and 1.25 MB of L2 per core on the Core 5 120. The boost clock on the Core 7 251E reaches 5.60 GHz versus 4.50 GHz on the Core 5 120. These specifications imply potential advantages in heavily threaded workloads, but the database does not contain measurements to confirm any win.

The Core 5 120 wins on benchmark availability and completeness. The Core 7 251E wins on specification breadth, but only on paper.
