Intel Core 5 120U vs Intel Core 7 253PQE Comparison

Head-to-Head Benchmarks

The benchmark data records a complete sweep for the Intel Core 7 253PQE across all 17 head-to-head comparisons, with zero wins recorded for the Intel Core 5 120U. The largest single margin appears in Cinebench R23 multi-core, where the Core 7 253PQE scores 31390 against the Core 5 120U's 6659, a delta of -78.8% from the perspective of the smaller chip. That 78.8% gap is the widest observed in the entire comparison set, indicating a fundamental difference in sustained multi-threaded capability rather than a marginal edge.

Single-core results tell a similar story, though with a narrower spread. In Cinebench R23 single-core, the Core 7 253PQE posts 4431 versus 1756.5 for the Core 5 120U, a -60.4% delta. The PassMark single-thread test shows the smallest relative difference of any benchmark in the set: 4389 against 3479, a -20.7% delta. This suggests that while the Core 7 253PQE holds a clear lead in per-thread performance, the advantage is more pronounced in workloads that scale across cores.

The Cinebench R15 multi-core test shows the Core 7 253PQE at 3163 against 1150.5, a -63.6% delta. In Cinebench R20 multi-core, the scores are 13183 versus 5349, a -59.4% delta, identical in percentage terms to the R20 single-core comparison where 1861 beats 755, also -59.4%. This consistency across the R20 suite indicates a uniform scaling factor between the two processors in that benchmark family.

PassMark integer math results show 137795 for the Core 7 253PQE versus 52280 for the Core 5 120U, a -62.1% delta. Floating-point math posts 105279 versus 36026, a -65.8% delta. Data compression shows 487335 versus 166432, also -65.8%, while data encryption records 25515 versus 10453, a -59% delta. Extended instructions (SIMD-heavy workloads) show 32390 versus 9299, a -71.3% delta, the second-largest gap after the R23 multi-core result. Prime number finding shows 206 versus 53, a -74.3% delta, meaning the Core 7 253PQE finds roughly four times as many primes in the same time window. Physics simulation via PassMark shows 2970 versus 937, a -68.5% delta. Random string sorting completes at 54222 versus 19060, a -64.8% delta.

The PassMark multithread composite confirms the overall pattern: 41656 versus 15042, a -63.9% delta. Across the full benchmark suite, no workload inverts the ordering, and no test comes within striking distance of parity. The closest margin remains single-threaded PassMark at -20.7%, while the median delta across all 17 tests sits near -64%, indicating that the Core 7 253PQE delivers roughly 2.7 to 3 times the throughput in most multi-threaded scenarios.

The Verdict

The recorded data supports only one conclusion for raw performance: the Intel Core 7 253PQE is decisively faster in every measured category. Its average benchmark score of 55919 places it in the 91st percentile of all CPUs in the database, while the Intel Core 5 120U averages 17898 and sits in the 72nd percentile. The nearest rivals for the Core 7 253PQE include the Intel Core i9-14900HX with an average score of 56004 and a delta of -0.2%, the AMD Ryzen AI Max 390 at 56273 (-0.6%), and the AMD Ryzen AI 9 HX PRO 470 at 56306 (-0.7%). These deltas are all within 1.1% of the Core 7 253PQE's average, meaning it competes at the very top of the desktop and high-end mobile performance tiers.

For the Core 5 120U, the nearest rivals are the AMD Ryzen 5 3600XT at 17891 (0% delta), the Intel Core 5 221TE at 17860 (+0.2%), the AMD Ryzen 5 1600 at 17994 (-0.5%), and the Intel Core 7 350 at 17779 (+0.7%). All four rivals sit within 0.7% of the Core 5 120U's average score, confirming that it occupies a mainstream performance band well below the Core 7 253PQE.

Given the benchmark record, the Core 7 253PQE is the appropriate selection for any workload where compute throughput determines completion time. The Core 5 120U remains functional for lighter tasks, but its 15 watt TDP and lower core clock configuration place it in a different performance class. The data shows no scenario where the Core 5 120U outperforms the Core 7 253PQE, so the decision rests on platform constraints rather than performance trade-offs.

Where Each One Wins

The Intel Core 7 253PQE wins every head-to-head benchmark in the database. That includes all Cinebench versions (R15, R20, R23) in both single-core and multi-core modes, all PassMark sub-tests (compression, encryption, extended instructions, prime finding, floating-point math, integer math, multithread, physics, random string sorting, single-thread), and the composite multithread score. There is no recorded category where the Intel Core 5 120U takes a win.

The Core 5 120U's closest relative performance appears in PassMark single-thread, where it trails by only 20.7%. This indicates that for simple single-threaded tasks, the performance gap narrows to roughly one-fifth, which could make the lower-power chip acceptable for lightweight interactive workloads. However, even this result does not constitute a win; it merely reduces the margin.

The Core 7 253PQE shows its largest advantages in Cinebench R23 multi-core (-78.8%), PassMark prime number finding (-74.3%), and PassMark extended instructions (-71.3%). These three tests emphasize sustained multi-core execution, integer-heavy loops, and SIMD throughput, respectively. Users running video rendering, scientific simulations, or encryption workloads would see the biggest time savings from the Core 7 253PQE.

The Core 5 120U offers no benchmark wins, but its platform characteristics (15 watt TDP, BGA 1744 socket, integrated Iris Xe Graphics 80EU) suggest it targets thin-and-light mobile designs where power draw and heat dissipation take priority over maximum throughput. The data does not quantify those trade-offs, but the performance record makes clear that the Core 5 120U trades compute capability for a lower power envelope.

Architecture Differences

The two processors diverge substantially in platform design despite both being Intel 10 nm parts. The Intel Core 5 120U uses the Raptor Lake architecture with the Raptor Lake-U codename, while the Intel Core 7 253PQE uses the Bartlett Lake codename. The Core 5 120U has 10 cores and 12 threads, while the Core 7 253PQE also has 10 cores but 20 threads, indicating that the Bartlett Lake part enables simultaneous multithreading on all cores whereas the Raptor Lake-U part limits thread count to 12.

Base and boost clocks differ sharply. The Core 5 120U runs at 1.40 GHz base and 5.00 GHz boost. The Core 7 253PQE runs at 3.50 GHz base and 5.70 GHz boost. The higher base clock of the Core 7 253PQE, combined with a 125 watt TDP against the Core 5 120U's 15 watts, explains the large multi-core performance margins. The 15 watt part must aggressively throttle to stay within its power envelope, while the 125 watt part can sustain high frequencies across all cores.

Cache hierarchy differs in size. Both parts share 80 KB of L1 per core, but the L2 cache is 1.25 MB per core on the Core 5 120U versus 2 MB per core on the Core 7 253PQE. The L3 cache is 12 MB shared on the Core 5 120U versus 33 MB shared on the Core 7 253PQE, a nearly threefold increase. Larger caches reduce memory traffic and benefit workloads with reusable data sets.

Memory support includes DDR4 and DDR5 for both, and both use dual-channel memory buses. The Core 7 253PQE lists a memory bandwidth of 89.6 GB/s, while the Core 5 120U does not have a recorded bandwidth figure. ECC memory support appears only on the Core 7 253PQE.

PCIe connectivity differs by generation and lane count. The Core 5 120U provides PCIe Gen 4 with 8 lanes (CPU only), while the Core 7 253PQE provides PCIe Gen 5 with 16 lanes (CPU only). This gives the desktop part twice the lane count and a newer generation, enabling faster data transfer to GPUs and NVMe storage.

The integrated graphics also differ. The Core 5 120U uses Iris Xe Graphics with 80 execution units, while the Core 7 253PQE uses UHD Graphics 770. The Core 5 120U targets mobile platforms with its BGA 1744 socket, while the Core 7 253PQE uses Intel Socket 1700 for desktop builds. Release dates place the Core 5 120U at 2024-01-07 and the Core 7 253PQE at 2026-03-08, with both listed as active production parts. The Core 7 253PQE has a launch MSRP of $409, while no launch MSRP is recorded for the Core 5 120U.
