Intel Core 7 253PQE vs Intel Core Ultra 5 135UL Comparison

Intel Core 7 253PQE vs Intel Core Ultra 5 135UL

The database shows a clear performance hierarchy between these two Intel desktop processors. The Intel Core 7 253PQE, a Bartlett Lake part with 10 cores and 20 threads, delivers substantially higher raw performance than the Intel Core Ultra 5 135UL, a Meteor Lake-PS part with 12 cores and 14 threads. The Core 7 253PQE sits at the 91st percentile among all CPUs with an average benchmark score of 55919, while the Core Ultra 5 135UL is at the 50th percentile with no recorded benchmark scores in the database. The Core 7 253PQE is the decisive choice for compute-heavy workloads, while the Core Ultra 5 135UL competes on efficiency and platform features.

Where Each One Wins

The Intel Core 7 253PQE wins every performance category where data exists. Its Cinebench R23 multi-core score of 31390 indicates strong sustained throughput for rendering, compilation, and other parallel workloads. Single-core performance is equally dominant, with a Cinebench R23 single-core score of 4431, a PassMark single-thread score of 4389, and a PassMark single_thread score of 4389. The Core 7 253PQE also leads in PassMark multi-thread performance at 41656, integer math at 137795, floating-point math at 105279, and data compression at 487335. These results place it among the top 9 percent of all CPUs in the database.

The Intel Core Ultra 5 135UL has no benchmark entries in the database, so its wins are limited to platform characteristics. It uses the Intel Socket 1851, a newer socket than the Core 7 253PQE's Intel Socket 1700. It also features a smaller process node at 7 nm versus 10 nm for the Core 7 253PQE, which supports its lower power envelope. The Core Ultra 5 135UL integrates Arc Xe-LPG 64EU graphics, which is a distinct feature set compared to the UHD Graphics 770 in the Core 7 253PQE. For workloads that rely on the integrated GPU, the Core Ultra 5 135UL holds the advantage on paper.

Architecture Differences

The two processors come from different architectural lineages. The Intel Core 7 253PQE is based on Bartlett Lake, part of the Core 7 generation, and uses a 10 nm process node fabricated by Intel. The Intel Core Ultra 5 135UL is based on Meteor Lake, specifically the Meteor Lake-PS variant, part of the Core Ultra Series 1, and uses a 7 nm process node also from Intel. The Core 7 253PQE has 10 cores and 20 threads, while the Core Ultra 5 135UL has 12 cores but only 14 threads, indicating a different core topology where not all cores are hyper-threaded.

Cache configurations differ significantly. The Core 7 253PQE 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 5 135UL carries 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 253PQE therefore has nearly three times the L3 cache, which supports its higher multi-core scores. The Core Ultra 5 135UL compensates with a larger per-core L1 cache, but this does not translate into benchmark wins in the recorded data.

Memory support also separates the two. The Core 7 253PQE supports both DDR4 and DDR5 memory, while the Core Ultra 5 135UL supports DDR5 with the specific configuration depending on the motherboard. Both use dual-channel memory buses with identical memory bandwidth of 89.6 GB/s. The Core 7 253PQE supports ECC memory, while the Core Ultra 5 135UL does not. PCIe connectivity differs as well: the Core 7 253PQE offers Gen 5 with 16 lanes from the CPU, while the Core Ultra 5 135UL offers Gen 4 with 8 lanes from the CPU.

The Verdict

The data indicates that the Intel Core 7 253PQE is the stronger processor for performance-sensitive desktop workloads. Its average benchmark score of 55919 places it just 0.2 percent behind the Intel Core i9-14900HX, 0.6 percent behind the AMD Ryzen AI Max 390, 0.7 percent behind the AMD Ryzen AI 9 HX PRO 470, and 1.1 percent behind the AMD Ryzen Threadripper PRO 3955WX. These rivals are all high-end parts, and the Core 7 253PQE matches their output within a narrow margin. Its Cinebench R23 multi-core score of 31390 and PassMark multi-thread score of 41656 confirm that it handles heavy parallel workloads with authority.

The Intel Core Ultra 5 135UL, by contrast, has no recorded benchmark scores and an average benchmark score of zero. Its 50th percentile ranking means it sits at the median of all CPUs, which is a far lower standing than the Core 7 253PQE's 91st percentile. The Core Ultra 5 135UL does offer a lower TDP of 15 watts versus 125 watts for the Core 7 253PQE, which is a notable efficiency advantage. It also uses a newer socket and a smaller process node, which may appeal to users planning a platform upgrade path. However, from a pure performance standpoint, the Core 7 253PQE is the clear selection.

Users who need maximum compute throughput for rendering, simulation, or content creation should choose the Intel Core 7 253PQE based on its benchmark dominance. Users who prioritize power efficiency, a newer platform, or the integrated Arc graphics should consider the Intel Core Ultra 5 135UL, but they must accept the lack of recorded performance data and the lower percentile ranking.
