Intel Core 7 253PTE vs Intel Core Ultra 7 155HL Comparison

Head-to-Head Benchmarks

The Intel Core 7 253PTE and the Intel Core Ultra 7 155HL are both 45 W desktop processors, but the data available for comparison is heavily weighted toward one side. The Core 7 253PTE has a complete set of benchmark results recorded in the database, while the Core Ultra 7 155HL has no recorded benchmark scores. This asymmetry means the quantitative analysis is limited to the Core 7 253PTE's absolute performance and its standing against other processors in the database, rather than a direct core-by-core comparison between these two specific CPUs.

The Core 7 253PTE posts an average benchmark score of 34,962, which places it in the 84th percentile of all CPUs tracked by the database. Its nearest rivals in the overall standings are the Intel Core i7-13800H with an average score of 34,988 (0.1% higher), the Intel Core i9-12900HX with 35,003 (0.1% higher), the Intel Xeon 6349P with 34,890 (0.2% lower), and the AMD Ryzen 5 150 with 34,881 (0.2% lower). These margins are extremely tight, all within two tenths of a percentage point, indicating that the Core 7 253PTE sits in a densely packed performance band where no single processor in its immediate vicinity holds a decisive advantage.

Looking at individual workload types, the Core 7 253PTE shows its strongest results in multi-threaded rendering. In Cinebench R23 multi-core, it scores 21,276 points, while its single-core score in the same test is 3,003 points. The R20 results follow a similar pattern: 8,935 multi-core and 1,261 single-core. The R15 test yields 2,144 multi-core and 302 single-core. The single-core to multi-core scaling across these Cinebench versions is consistent with a processor that scales well when all threads are active.

In PassMark tests, the Core 7 253PTE records 25,031 in the multithread test and 3,794 in single-thread. Integer math scores 119,552, floating point math scores 67,209, and extended instructions score 17,099. Data compression reaches 275,828, while data encryption scores 15,500. Random string sorting produces 28,227, and find prime numbers returns 82. Physics simulation records 1,318.

Where Each One Wins

The Core 7 253PTE wins on raw performance across every metric where the database has recorded data. With 10 cores and 20 threads, it delivers strong multi-threaded throughput, as shown by its Cinebench R23 multi-core score of 21,276 and its PassMark multithread score of 25,031. Its boost clock of 5.40 GHz also gives it a clear advantage in single-threaded workloads, reflected in the 3,794 PassMark single-thread score and the 3,003 Cinebench R23 single-core result.

The Core Ultra 7 155HL has no benchmark results in the database, so there is no recorded data to demonstrate any workload where it wins. The database shows zero average benchmark score for this processor, which means the analysis cannot assign it a victory in any specific application category. Its specifications indicate a different design direction: 16 cores and 22 threads, a lower boost clock of 4.80 GHz, and a smaller 24 MB shared L3 cache compared to the Core 7 253PTE's 33 MB. Without benchmark data, however, these specifications cannot be translated into measured performance advantages.

The Core 7 253PTE also holds the advantage in memory support flexibility, as it supports both DDR4 and DDR5, while the Core Ultra 7 155HL supports DDR5 only, with compatibility depending on the motherboard. The Core 7 253PTE includes ECC memory support, which the Core Ultra 7 155HL does not offer. For workloads that depend on ECC reliability, such as data integrity sensitive tasks, the Core 7 253PTE is the only one of the two that provides this capability.

The Core 7 253PTE's PCIe implementation is also more expansive: it uses Gen 5 with 16 lanes from the CPU, while the Core Ultra 7 155HL uses Gen 4 with 8 lanes. This gives the Core 7 253PTE a wider and faster connection path for expansion devices and GPUs, a meaningful difference in systems where bandwidth to peripherals matters.

Neither processor has an unlocked multiplier.

Architecture Differences

The Core 7 253PTE is built on Bartlett Lake architecture, which is part of the Core 7 generation, while the Core Ultra 7 155HL uses Meteor Lake architecture, specifically the Meteor Lake-PS codename, and belongs to the Core Ultra Series 1 generation. The Core 7 253PTE uses a 10 nm process node, and the Core Ultra 7 155HL uses a 7 nm process node. Both are fabricated by Intel.

The production status for both processors is Active, and both target the desktop market segment. The Core Ultra 7 155HL has a Series designation of Core Ultra Series 1, whereas the Core 7 253PTE has no series designation recorded. The codename for the Core 7 253PTE is Bartlett Lake, and for the Core Ultra 7 155HL it is Meteor Lake-PS.

The generation labels in the database reflect the different naming structures: the Core 7 253PTE is listed as Core 7 (Bartlett Lake), and the Core Ultra 7 155HL is listed as Ultra 7 (Meteor Lake-PS). These architecture differences align with the different socket requirements, with the Core 7 253PTE using Socket 1700 and the Core Ultra 7 155HL using Socket 1851, meaning the two processors are not interchangeable on the same motherboard.

The Core Ultra 7 155HL's higher core count of 16 versus 10, combined with its lower 7 nm process node, suggests a design focused on parallelism and efficiency, while the Core 7 253PTE's higher boost clock of 5.40 GHz and larger 33 MB L3 cache suggest a design emphasizing single-thread speed and larger shared cache pools. The benchmark data confirms the Core 7 253PTE's strong performance in both single and multi-threaded workloads, with its Cinebench R23 single-core score of 3,003 and multi-core score of 21,276 placing it in the 84th percentile overall. The Core Ultra 7 155HL, lacking recorded benchmark scores, cannot be evaluated on the same terms, leaving its architectural advantages unmeasured in the database.
