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

Head-to-Head Benchmarks

The Intel Core 7 253PTE and Intel Core Ultra 7 155UL present a lopsided comparison in the recorded database. The Core 7 253PTE has a full set of benchmark results across Cinebench and Passmark suites, while the Core Ultra 7 155UL has no recorded benchmark scores in the database. Consequently, every measurable performance comparison favors the Core 7 253PTE by default, though the absence of data for the Ultra 7 155UL limits direct head-to-head analysis.

The Core 7 253PTE delivers a Cinebench R23 multi-core score of 21276 and a single-core score of 3003. Its Cinebench R20 results are 8935 multi-core and 1261 single-core, and Cinebench R15 shows 2144 multi-core and 302 single-core. In Passmark tests, the Core 7 253PTE records 25031 for multithread, 3794 for single thread, 119552 for integer math, 67209 for floating point math, 275828 for data compression, and 15500 for data encryption. These scores place the processor at the 84th percentile among all CPUs in the database, with an average benchmark score of 34962.

The percentile ranking provides context for the Core 7 253PTE's standing. Its nearest rival in average score is the Intel Core i9-12900HX at 35003, which is 0.1% ahead. The Intel Core i7-13800H scores 34988, also 0.1% ahead. On the other side, the Intel Xeon 6349P scores 34890, putting the Core 7 253PTE 0.2% ahead, and the AMD Ryzen 5 150 scores 34881, also 0.2% behind the Core 7 253PTE. These deltas are tiny, indicating that the Core 7 253PTE sits in a tightly contested performance band where a few points separate it from its immediate competitors.

For the Core Ultra 7 155UL, the database contains no benchmark entries, no average score, and no nearest rivals. Its percentile ranking is 50, which is the median by definition, but this figure carries no performance weight without actual test data. The practical implication is that any performance comparison between these two processors cannot be made from measured results, only from architectural specifications.

Architecture Differences

The two processors diverge significantly in their underlying designs. The Intel Core 7 253PTE uses the Bartlett Lake codename and belongs to the Core 7 generation. It is built on a 10 nm process node at Intel's foundry. The processor has 10 cores and 20 threads, with a base clock of 1.80 GHz and a boost clock of 5.40 GHz. Its thermal design power is 45 watts. The cache hierarchy consists of 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. Memory support includes DDR4 and DDR5 across a dual-channel bus with 89.6 GB/s of bandwidth. ECC memory is supported. The PCIe implementation is Gen 5 with 16 lanes available from the CPU. Integrated graphics come as UHD Graphics 730. It uses Intel Socket 1700 and was released on 2026-03-08 with a launch MSRP of $384.

The Intel Core Ultra 7 155UL uses the Meteor Lake architecture with the Meteor Lake-PS codename, part of the Core Ultra Series 1 generation. It is fabricated on a 7 nm process node at Intel's foundry. The processor has 12 cores and 14 threads, with a base clock of 1.70 GHz and a boost clock of 4.80 GHz. Its thermal design power is 15 watts, which is one-third of the Core 7 253PTE's 45-watt TDP. The cache layout includes 112 KB of L1 per core, 2 MB of L2 per core, and 12 MB of shared L3 cache. Memory support is DDR5, with capacity depending on the motherboard, across a dual-channel bus with 89.6 GB/s of bandwidth. ECC memory is not supported. The PCIe implementation is Gen 4 with 8 lanes from the CPU. Integrated graphics are Arc Xe-LPG with 64 execution units. It uses Intel Socket 1851 and was released on 2024-04-07 with a launch MSRP of $426.

The core count and thread count relationship reveals a fundamental design difference. The Core 7 253PTE has 10 cores and 20 threads, indicating hyperthreading where each core supports two threads. The Core Ultra 7 155UL has 12 cores but only 14 threads, which implies a mix of performance and efficiency cores where some cores do not support hyperthreading. The Core 7 253PTE has a higher boost clock by 0.60 GHz, which contributes to its stronger single-thread performance in the recorded benchmarks. The Core Ultra 7 155UL has a higher L1 cache per core at 112 KB versus 80 KB, but the Core 7 253PTE has substantially more shared L3 cache at 33 MB versus 12 MB.

The process node difference is notable: 10 nm for the Core 7 253PTE versus 7 nm for the Core Ultra 7 155UL. The smaller process node typically enables better power efficiency, which aligns with the Core Ultra 7 155UL's 15-watt TDP. The Core 7 253PTE's higher TDP of 45 watts allows for higher clock speeds and more sustained performance under load.

Socket compatibility differs completely. The Core 7 253PTE uses Intel Socket 1700, while the Core Ultra 7 155UL uses Intel Socket 1851. These sockets are not interchangeable, so platform choice is dictated by the processor. PCIe generation also differs, with the Core 7 253PTE offering Gen 5 with 16 lanes versus Gen 4 with 8 lanes on the Core Ultra 7 155UL. This affects expansion bandwidth for graphics cards and NVMe storage.

The Verdict

The recorded data shows a clear situation: the Intel Core 7 253PTE has comprehensive benchmark results, while the Intel Core Ultra 7 155UL has none. For users seeking measured performance, the Core 7 253PTE is the only option with verified scores. Its 84th percentile ranking and average benchmark score of 34962 place it among capable desktop processors, with its nearest rivals within 0.2% either direction.

The Core Ultra 7 155UL's 50th percentile ranking is not a measured performance level but a default median value, since it has no recorded benchmarks. Its architecture suggests a power-leaning design with a 15-watt TDP, 12 cores, and 14 threads, but without test data, its actual performance cannot be quantified.

The Core 7 253PTE targets users who need high boost clocks, a large shared L3 cache, ECC memory support, Gen 5 PCIe connectivity, and a higher thread count. The Core Ultra 7 155UL targets users who prioritize lower power consumption, a smaller process node, and a newer socket, with the tradeoff of fewer threads, no ECC support, and lower PCIe generation.

The multithread score of 25031 and single-thread score of 3794 round out the profile.

The Core 7 253PTE's 33 MB of shared L3 cache versus 12 MB on the Core Ultra 7 155UL suggests an advantage in workloads that benefit from large cache residency. Its higher boost clock of 5.40 GHz versus 4.80 GHz indicates stronger single-threaded responsiveness. The Gen 5 PCIe implementation with 16 lanes provides more expansion bandwidth than the Gen 4 with 8 lanes on the Core Ultra 7 155UL.

The Core Ultra 7 155UL wins on power efficiency, with a 15-watt TDP versus 45 watts for the Core 7 253PTE. Its 7 nm process node is smaller than the 10 nm node of the Core 7 253PTE, which typically corresponds to lower power draw per transistor. The Core Ultra 7 155UL also has more physical cores at 12 versus 10, and a higher L1 cache per core at 112 KB versus 80 KB. Its integrated graphics, Arc Xe-LPG with 64 execution units, is a different class of GPU compared to the UHD Graphics 730 on the Core 7 253PTE, though neither has benchmark scores in the database.

The Core Ultra 7 155UL uses the newer Intel Socket 1851, while the Core 7 253PTE uses Intel Socket 1700. For users building on a newer platform, the Core Ultra 7 155UL offers compatibility with that socket generation. The Core Ultra 7 155UL also has a lower launch MSRP of $426 compared to $384 for the Core 7 253PTE, though the Core 7 253PTE's higher price corresponds to its measured performance advantage.

For workloads that depend on measured multi-threaded performance, high boost clocks, large shared cache, ECC memory, and Gen 5 PCIe bandwidth, the Intel Core 7 253PTE is the clear choice from the available data. For workloads that prioritize low power consumption, a smaller process node, and a newer socket platform, the Intel Core Ultra 7 155UL has architectural advantages, but its lack of recorded benchmarks means its actual performance remains unverified in the database.
