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

The Intel Core 5 120U and Intel Core 7 253PTE are both 10-core Intel processors, but they are engineered for entirely different segments of the market. The recorded data shows the Core 7 253PTE winning all 17 head-to-head benchmark comparisons, making the analysis a clear case of performance stratification rather than a competitive tie. The Core 5 120U is a mobile-focused chip with a 15 TDP, while the Core 7 253PTE is a desktop part with a 45 TDP and a 2026 release date, which explains the significant performance gap.

Where Each One Wins

The benchmark results are unambiguous: the Intel Core 7 253PTE wins every single recorded test. The Intel Core 5 120U does not register a single victory across the 17 head-to-head comparisons. This makes the use-case split straightforward. The Core 5 120U is positioned for thin-and-light mobile devices where power efficiency and adequate performance for daily tasks are the priorities, while the Core 7 253PTE is designed for desktop workloads that demand sustained multi-core throughput.

The Core 5 120U sits in the 72nd percentile of all CPUs, with an average benchmark score of 17898. Its nearest rivals include the AMD Ryzen 5 3600XT (average score 17891, delta 0 percent) and the Intel Core 5 221TE (average score 17860, delta 0.2 percent). This places it in a competitive range with older desktop parts, but its 15 TDP and mobile socket (Intel BGA 1744) indicate its role is to deliver that level of performance in a power-constrained environment.

The Core 7 253PTE, by contrast, reaches the 84th percentile of all CPUs with an average benchmark score of 34962. Its nearest rivals are high-end mobile and desktop chips like the Intel Core i7-13800H (average score 34988, delta -0.1 percent) and the Intel Core i9-12900HX (average score 35003, delta -0.1 percent). This places it in the same performance class as flagship laptop processors from a previous generation. The 253PTE is the clear choice for desktop users who need maximum compute capability, particularly for multi-threaded applications that can leverage its 20 threads.

Architecture Differences

The two processors share the same 10 nm process node and are both built by Intel, but they diverge significantly in architecture and platform support. The Core 5 120U uses the Raptor Lake architecture with the Raptor Lake-U codename, and it has 10 cores and 12 threads. The Core 7 253PTE uses the Bartlett Lake codename and has 10 cores and 20 threads, indicating a different core configuration that doubles the thread count through hyper-threading across all cores.

Cache hierarchies differ substantially. The Core 5 120U has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 12 MB of shared L3 cache. The Core 7 253PTE also has 80 KB of L1 per core, but its L2 is 2 MB per core and its L3 is 33 MB shared. This larger cache allocation on the 253PTE contributes to its higher performance in data-heavy workloads, as indicated by the PassMark data compression and integer math tests.

The sockets are incompatible: the Core 5 120U uses Intel BGA 1744 (a soldered mobile package), while the Core 7 253PTE uses Intel Socket 1700 (a desktop LGA socket). The Core 5 120U has a base clock of 1.40 GHz and a boost clock of 5.00 GHz, whereas the Core 7 253PTE has a base clock of 1.80 GHz and a boost clock of 5.40 GHz. The 253PTE also supports ECC memory and has a dual-channel memory bus with 89.6 GB/s of memory bandwidth, features that are absent or unspecified for the 120U.

PCIe support is another differentiator. The Core 5 120U offers PCIe Gen 4 with 8 lanes (CPU only), while the Core 7 253PTE provides PCIe Gen 5 with 16 lanes (CPU only). The integrated graphics also differ: the 120U uses Iris Xe Graphics 80EU, while the 253PTE uses UHD Graphics 730. The 253PTE is a desktop part with a 45 TDP, while the 120U is a mobile part with a 15 TDP, reflecting the power envelope required for each platform.

Head-to-Head Benchmarks

The performance gap is most dramatic in multi-core workloads. In Cinebench R23 multi-core, the Core 7 253PTE scores 21276 against the Core 5 120U's 6659, a delta of -68.7 percent from the 120U's perspective. This is the largest single win for the 253PTE. In Cinebench R20 multi-core, the 253PTE scores 8935 versus 5349, a -40.1 percent delta. The R15 multi-core test shows 2144 versus 1150.5, a -46.3 percent delta. These results indicate that the 253PTE delivers more than three times the multi-threaded performance of the 120U in the most demanding rendering workload.

Single-core performance also favors the 253PTE, though by a smaller margin. In Cinebench R23 single-core, the 253PTE scores 3003 against 1756.5, a -41.5 percent delta. Cinebench R20 single-core shows 1261 versus 755, a -40.1 percent delta. The PassMark single-thread test shows 3794 versus 3479, a delta of -8.3 percent, which is the smallest margin in the entire comparison. This suggests that the 253PTE's higher boost clock of 5.40 GHz provides a modest but consistent advantage in lightly threaded tasks.

The PassMark suite reveals where the 253PTE's larger cache and higher thread count pay off. In integer math, the 253PTE scores 119552 versus 52280, a -56.3 percent delta. Floating point math shows 67209 versus 36026, a -46.4 percent delta. Extended instructions show 17099 versus 9299, a -45.6 percent delta. Data compression scores 275828 versus 166432, a -39.7 percent delta. Data encryption shows 15500 versus 10453, a -32.6 percent delta. The 253PTE also wins in PassMark physics (1318 versus 937, -28.9 percent), random string sorting (28227 versus 19060, -32.5 percent), and find prime numbers (82 versus 53, -35.4 percent). The multithread score is 25031 versus 15042, a -39.9 percent delta. Every metric confirms the 253PTE's dominance, with the smallest gap being the 8.3 percent difference in single-threaded PassMark performance.
