Intel Core 7 253PE vs Intel Core Ultra 7 165UL Comparison

Head-to-Head Benchmarks

The benchmark database contains no direct head-to-head measurements between the Intel Core 7 253PE and the Intel Core Ultra 7 165UL. The head-to-head benchmark array is empty, and the Core Ultra 7 165UL has no recorded benchmark scores in the database at all. Its average benchmark score is listed as 0, and its percentile rank among all CPUs is 50.

What the database does provide is a full benchmark profile for the Core 7 253PE. In Cinebench R23 multi-core, it scores 24880 points, while its single-core score is 3512. In Cinebench R20, the multi-core result is 10449 and single-core is 1475. The Cinebench R15 run yields 2507 multi-core and 354 single-core. PassMark results include a multi-thread score of 29271, a single-thread score of 3955, integer math at 114158, floating point math at 80870, extended instructions at 21806, data compression at 339133, data encryption at 18385, physics at 1845, random string sorting at 32777, and prime number finding at 138.

Without any scores recorded for the Core Ultra 7 165UL, the database cannot establish which part wins any specific workload. The comparison must rely on architectural differences, core and thread counts, clock ranges, cache sizes, and platform features.

Architecture Differences

The two processors come from different Intel families and are built on different process nodes. The Core 7 253PE uses the Bartlett Lake codename, is fabricated on a 10 nm process at Intel, and belongs to the Core 7 generation. The Core Ultra 7 165UL uses the Meteor Lake architecture, specifically the Meteor Lake-PS codename, is built on a 7 nm process at Intel, and belongs to the Core Ultra Series 1 generation.

Core and thread counts differ substantially. The Core 7 253PE has 10 cores and 20 threads, taking advantage of simultaneous multithreading. The Core Ultra 7 165UL has 12 cores but only 14 threads, which suggests its core configuration is not purely symmetrical and does not fully double thread count per core. The Core 7 253PE therefore presents more logical processors to the operating system, which can benefit heavily threaded workloads that scale with thread count.

Clock speeds also differ. The Core 7 253PE has a base clock of 2.50 GHz and a boost clock of 5.50 GHz, while the Core Ultra 7 165UL runs at 1.70 GHz base and 4.90 GHz boost. The Core 7 253PE holds a clear frequency advantage in both base and boost operation.

Cache layouts differ in size and allocation. The Core 7 253PE carries 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The Core Ultra 7 165UL has 112 KB of L1 cache per core, 2 MB of L2 cache per core, and only 12 MB of shared L3 cache. The Core 7 253PE has nearly three times the L3 capacity, which can improve performance in workloads that cycle through large data sets.

Power envelopes are very different. The Core 7 253PE is rated at 65 W TDP, while the Core Ultra 7 165UL is rated at 15 W TDP. That 15 W rating indicates a low-power design intended for thermally constrained systems.

Memory support differs in one important respect. Both parts support dual-channel memory with a memory bandwidth of 89.6 GB/s. The Core 7 253PE supports DDR4 and DDR5, while the Core Ultra 7 165UL supports DDR5 with the note that support depends on the motherboard. ECC memory is supported on the Core 7 253PE but not on the Core Ultra 7 165UL.

Platform connectivity differs as well. The Core 7 253PE uses Intel Socket 1700 and provides PCIe Gen 5 with 16 lanes from the CPU. The Core Ultra 7 165UL uses Intel Socket 1851 and provides PCIe Gen 4 with 8 lanes from the CPU.

Integrated graphics also differ. The Core 7 253PE includes UHD Graphics 730, while the Core Ultra 7 165UL includes Arc Xe-LPG 64EU, which is a different and newer graphics architecture.

Release timing is not identical. The Core Ultra 7 165UL was released in April 2024, while the Core 7 253PE was released in March 2026. The Core 7 253PE lists a launch MSRP of $384. The Core Ultra 7 165UL lists a launch MSRP of $447.

The Verdict

The database contains benchmark results for only one of these two processors. The Intel Core 7 253PE has a full set of Cinebench and PassMark scores, a percentile rank of 87 among all CPUs, and an average benchmark score of 40557. The Intel Core Ultra 7 165UL has no recorded benchmark scores and an average benchmark score of 0, with a percentile rank of 50.

From the recorded data, the Core 7 253PE is the only part with measurable performance evidence. Its nearest rivals in the database are the Intel Core 5 223PE with an average score of 40585 and a delta of -0.1%, the Intel Core Ultra X7 368H with 40518 and a delta of 0.1%, the Intel Xeon 6357P with 40630 and a delta of -0.2%, and the AMD Ryzen 9 7940H with 40431 and a delta of 0.3%. The Core 7 253PE sits within a narrow band of these processors, all within roughly a third of a percent of each other.

For the Core Ultra 7 165UL, the lack of recorded scores means the database cannot place it against any rival. Its 12 physical cores might help in some parallel workloads, but its 14 threads are fewer than the 20 threads of the Core 7 253PE. Its 4.90 GHz boost clock is lower, its 12 MB L3 cache is smaller, and its PCIe Gen 4 with 8 lanes is narrower than PCIe Gen 5 with 16 lanes. Its main advantages are the 7 nm process node, the lower 15 W TDP, and the Arc Xe-LPG 64EU integrated graphics.

The data supports selecting the Core 7 253PE for any workload where the recorded benchmarks are relevant. The Core Ultra 7 165UL may suit a system where low power draw is the priority, but no benchmark evidence in the database backs that choice.

Where Each One Wins

The Intel Core 7 253PE wins in every category where the database has recorded measurements. Its 20 threads, 5.50 GHz boost clock, 33 MB L3 cache, DDR4 and DDR5 support, ECC capability, and PCIe Gen 5 with 16 lanes give it the measurable edge. The recorded PassMark multi-thread score of 29271 and Cinebench R23 multi-core score of 24880 demonstrate strong parallel throughput. Its single-thread PassMark score of 3955 and Cinebench R23 single-core score of 3512 show it also handles lightly threaded work well.

The Intel Core Ultra 7 165UL wins only in areas that do not require benchmark scores. Its 15 W TDP is far lower than 65 W, making it the better choice for a system with strict power or thermal limits. Its 12 physical cores exceed the 10 of the Core 7 253PE, which might help in specific workloads that favor many physical cores over thread count, although the database has no scores to confirm this. Its 7 nm process node is more advanced than the 10 nm node of the Core 7 253PE. Its Arc Xe-LPG 64EU integrated graphics is a different architecture than UHD Graphics 730 and may offer different media or display capabilities.

The Core Ultra 7 165UL also uses Intel Socket 1851, while the Core 7 253PE uses Intel Socket 1700, meaning the two parts require different motherboards. The Core Ultra 7 165UL has a higher launch MSRP of $447 compared to $384 for the Core 7 253PE. For any workload measured in the database, the Core 7 253PE is the only one with recorded evidence of performance.
