Intel Core 5 120 vs Intel Core 7 253PE Comparison

The Verdict

The benchmark data presents a clear hierarchy between these two Intel desktop processors. The Intel Core 7 253PE wins every single recorded benchmark comparison, 17 out of 17 head-to-head tests. The Core 5 120 does not secure a single victory in any workload category, whether single-threaded, multi-threaded, or specialized instruction tests.

The Core 7 253PE operates in a different performance class entirely. Its average benchmark score of 40557 places it at the 87th percentile of all CPUs in the database, while the Core 5 120 achieves an average score of 25362 and sits at the 77th percentile. The Core 5 120's nearest rivals include the AMD Ryzen 5 5600X3D with a nearly identical average score of 25365 and the Intel Core i5-13400F at 25292, confirming that the Core 5 120 competes in the upper mid-range tier. The Core 7 253PE, by contrast, sits alongside the Intel Core 5 223PE at 40585 and the AMD Ryzen 9 7940H at 40431.

For users whose workloads align with the benchmark suite, the Core 7 253PE is the straightforward choice. The data shows no scenario where the Core 5 120 offers a performance advantage. The Core 5 120 remains a relevant option specifically for systems where the lower launch MSRP of $211 versus $384 for the Core 7 253PE is the deciding factor, though pricing analysis is outside the scope of this benchmark review. The Core 5 120 also carries a 65 TDP identical to the Core 7 253PE, so power consumption does not differentiate them.

Architecture Differences

The two processors share several foundational characteristics. Both use the Intel Socket 1700, a 10 nm process node from Intel's own foundry, dual-channel memory support for DDR4 and DDR5, and PCIe Gen 5 with 16 CPU lanes. Both integrate UHD Graphics 730 and are locked processors with no unlocked multiplier. Both are active production parts aimed at the desktop market segment.

The Core 5 120 belongs to the Raptor Lake architecture, specifically the Raptor Lake-R die with a die size of 163 mm². It provides 6 cores and 12 threads. Its cache layout includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache. The base clock is 2.50 GHz with a boost clock of 4.50 GHz. It does not support ECC memory. Its release date is recorded as 2025-07-30.

The Core 7 253PE uses the Bartlett Lake codename and provides 10 cores and 20 threads. The L1 cache remains 80 KB per core, but L2 expands to 2 MB per core, and L3 grows to 33 MB shared. The base clock matches at 2.50 GHz, but the boost clock reaches 5.50 GHz, a full 1 GHz higher than the Core 5 120. The Core 7 253PE supports ECC memory and records a memory bandwidth of 89.6 GB/s, a figure not listed for the Core 5 120. Its release date is recorded as 2026-03-08.

The core count difference of 10 versus 6, combined with 20 threads versus 12, explains much of the multi-threaded performance gap. The larger 33 MB L3 cache on the Core 7 253PE provides additional headroom for cache-sensitive workloads. The higher boost clock of 5.50 GHz versus 4.50 GHz contributes to its single-thread advantage.

Head-to-Head Benchmarks

The Core 7 253PE dominates every recorded benchmark, but the margin varies significantly by workload type. The narrowest gap appears in single-threaded PassMark tests, where the Core 7 253PE scores 3955 against 3595 for the Core 5 120, a 9.1% advantage. This is the closest result in the entire comparison and indicates that the Core 5 120's single-core performance remains respectable relative to its larger sibling.

The Cinebench suite shows consistent deltas across all tested versions. In Cinebench R15, the Core 7 253PE scores 2507 multi-core versus 1840 for the Core 5 120, a 26.6% lead. Single-core R15 shows 354 versus 259, also a 26.8% gap. Cinebench R20 repeats the pattern: 10449 versus 7667 multi-core and 1475 versus 1082 single-core, both at 26.6%. Cinebench R23 follows with 24880 versus 18255 multi-core and 3512 versus 2577 single-core, again 26.6%. The consistency of the 26.6% delta across all six Cinebench results suggests a scaling factor tied directly to the core and thread count difference rather than workload-specific behavior.

The PassMark suite reveals larger divergences in specialized workloads. Integer math shows the biggest gap: the Core 7 253PE scores 114158 against 60462 for the Core 5 120, a 47% advantage. Floating point math follows closely with 80870 versus 45383, a 43.9% lead. Prime number finding shows 138 versus 77, a 44.2% delta. Data encryption shows 18385 versus 11131, a 39.5% gap, while data compression shows 339133 versus 219535, a 35.3% difference. Extended instructions score 21806 versus 14264, a 34.6% lead. Random string sorting shows 32777 versus 21499, a 34.4% gap. PassMark multithread scores 29271 versus 18597, a 36.5% difference, and physics scores 1845 versus 1333, a 27.8% gap.

The pattern is clear: integer-heavy and math-heavy workloads amplify the Core 7 253PE's advantage beyond the baseline 26.6% seen in Cinebench, while single-threaded tests compress the gap to 9.1%. The Core 5 120's relative strength appears in single-threaded scenarios, where the 4.50 GHz boost clock partially compensates for the architectural differences.

Where Each One Wins

The Core 7 253PE wins in every measured category, so the analysis shifts to which workloads show the largest and smallest margins. The Core 5 120's best relative showing comes in PassMark single-thread performance, where the 9.1% gap is the only result below double digits. This indicates that lightly threaded applications, such as older games or basic productivity tasks that depend on a single core, would see the least difference between the two processors.

The Core 7 253PE shows its largest advantage in PassMark integer math at 47%, followed by floating point math at 43.9% and prime number finding at 44.2%. These results point to compute-heavy workloads, including scientific calculations, financial modeling, and any application that stresses arithmetic units, as the clearest beneficiaries of the Core 7 253PE's additional cores and higher boost clock.

Data encryption shows a 39.5% gap, making the Core 7 253PE substantially stronger for encryption-heavy tasks such as database encryption, VPN gateways, or secure file operations. Data compression shows a 35.3% gap, relevant for archiving, backup systems, and file server workloads. The extended instructions test shows a 34.6% gap, covering SIMD and specialized instruction set workloads.

The Cinebench suite consistently shows a 26.6% gap across all versions and both single and multi-core tests. This consistency suggests that Cinebench's rendering workload scales predictably with the core and thread count difference, making it a reliable baseline for general CPU performance expectations.

The PassMark multithread score shows a 36.5% gap, while physics shows 27.8%. The random string sorting test shows 34.4%. These results confirm that the Core 7 253PE's advantage persists across diverse workload types, from memory-heavy sorting to physics simulation.

For the Core 5 120, the data shows no workload where it leads. Its role in the product stack is defined by its lower launch MSRP of $211 and identical 65 TDP, making it a candidate for systems where the additional performance of the Core 7 253PE is not required. The Core 7 253PE, at the 87th percentile of all CPUs, delivers benchmark results that place it among significantly more capable processors, with nearest rivals including the Intel Core 5 223PE and AMD Ryzen 9 7940H. The Core 5 120, at the 77th percentile, aligns with the AMD Ryzen 5 5600X3D and Intel Core i5-13400F. Users targeting the higher performance tier should select the Core 7 253PE; those constrained to the lower tier will find the Core 5 120's single-thread performance within 9.1% of the larger chip, though multi-threaded workloads will show far larger differences.
