Intel Core 7 253PQE vs Intel Core Ultra 5 245HX Comparison

Intel Core 7 253PQE vs Intel Core Ultra 5 245HX is a comparison between two distinctly different Intel designs, one rooted in the desktop space and the other in high-performance mobile. The data shows a clear split: the Core 7 253PQE dominates integer-heavy and data-heavy workloads, while the Core Ultra 5 245HX leads in nearly all Cinebench multi-threaded and single-threaded tests, plus a few specific Passmark tasks. The newer, more efficient Arrow Lake architecture of the Ultra 5 provides a broad edge in rendering and encryption, but the Bartlett Lake chip's higher boost clock and larger L3 cache give it decisive wins in math and compression. The recorded data reveals that the average benchmark score for the Core 7 253PQE (55919) sits well above the Core Ultra 5 245HX (48287), even though the latter wins more individual tests. This paradox centers on the magnitude of those wins: the Core 7's 49.5% lead in integer math and 24% lead in data compression outweigh the Ultra 5's narrower, albeit more frequent, victories.

Where Each One Wins

The use-case split is stark. The Intel Core 7 253PQE wins 6 of 17 head-to-head benchmarks, and its victories are concentrated in workloads that rely on raw integer throughput and large shared caches. The Passmark integer math test shows a 49.5% advantage, and the data compression test shows a 24% lead. Passmark multithread (9.4%), physics (17.6%), and random string sorting (13.9%) also favor the Core 7. These are classic CPU-bound tasks: number crunching, sorting, physics simulations, and general-purpose integer code. The Core 7 253PQE also wins the extended instructions test by 3.8%, indicating an edge in SIMD-heavy integer workloads.

The Intel Core Ultra 5 245HX wins 11 of 17 benchmarks. Its clean sweep of all six Cinebench tests (R15, R20, R23, both single and multi-core) shows a consistent 3% advantage in each. The data also shows wins in data encryption (15% lead), find prime numbers (42.6% lead), and floating point math (12.8% lead). The Ultra 5 also edges out the Core 7 in Passmark single-thread tests by 2.1%. This profile points to rendering engines, cryptographic operations, floating-point simulation, and single-threaded application logic as the Ultra 5's territory. The Cinebench results specifically indicate a stronger multi-core rendering performance, despite having fewer threads (14 threads vs. 20 threads).

Architecture Differences

The two chips represent divergent design philosophies. The Core 7 253PQE uses the Bartlett Lake codename on a 10 nm process node fabricated by Intel, targeting the desktop segment with an Intel Socket 1700. It has 10 cores and 20 threads, with a base clock of 3.50 GHz and a boost clock of 5.70 GHz. Its thermal design power is 125 watts. The cache layout consists of 80 KB of L1 per core, 2 MB of L2 per core, and a substantial 33 MB of shared L3 cache. Memory support includes both DDR4 and DDR5 in a dual-channel configuration, delivering 89.6 GB/s bandwidth. It also supports ECC memory and includes UHD Graphics 770. The CPU provides Gen 5 PCIe with 16 lanes.

The Core Ultra 5 245HX is a completely different package. It belongs to the Core Ultra Series 2, uses the Arrow Lake architecture with the Arrow Lake-HX codename, and is built on a 3 nm process node at TSMC. This is a mobile processor using Intel BGA 2114, with a 55-watt TDP. It has 14 cores but only 14 threads, meaning it uses a different core configuration without hyperthreading on all cores. Its base clock is 3.10 GHz and boost clock is 5.10 GHz. The cache is much larger per core (192 KB L1 and 3 MB L2) but the shared L3 is smaller at 24 MB. It supports only DDR5 memory, dual-channel, with higher bandwidth of 102.4 GB/s. No ECC support is present. The integrated graphics are Arc Xe-LPG Graphics 48EU. The CPU offers Gen 5 PCIe with 20 lanes. The transistor count is listed at 17,800 million on a 243 mm² die, versus no transistor or die size data for the Core 7. The Ultra 5 also has an unlocked multiplier, while the Core 7 is locked. The release dates differ: the Core 7 launched later (2026-03-08) than the Ultra 5 (2025-01-12).

Head-to-Head Benchmarks

The Cinebench results are uniform. In R15 multi-core, the Ultra 5 scores 3261 versus 3163 for the Core 7, a 3% delta. R15 single-core shows 460 versus 446, also a 3% delta. R20 multi-core: 13590 vs. 13183, 3% delta. R20 single-core: 1918 vs. 1861, 3% delta. R23 multi-core: 32358 vs. 31390, 3% delta. R23 single-core: 4568 vs. 4431, 3% delta. The consistency suggests a per-clock efficiency advantage in the Arrow Lake architecture, despite the lower boost clock (5.10 vs. 5.70 GHz) and fewer threads (14 vs. 20).

The Passmark results are more varied. The Core 7's biggest win is integer math: 137795 vs. 92150, a 49.5% delta. Data compression shows 487335 vs. 393071, a 24% delta. Physics: 2970 vs. 2526, a 17.6% delta. Random string sorting: 54222 vs. 47616, a 13.9% delta. Multithread: 41656 vs. 38069, a 9.4% delta. Extended instructions: 32390 vs. 31212, a 3.8% delta.

The Ultra 5's biggest win is find prime numbers: 359 vs. 206, a 42.6% delta. Data encryption: 30022 vs. 25515, a 15% delta. Floating point math: 120735 vs. 105279, a 12.8% delta. Single thread: 4481 vs. 4389, a 2.1% delta. The prime number test result is particularly telling: it shows the Ultra 5's core design handles this specific algorithm much better, likely due to architectural improvements in the integer pipeline or branch prediction, despite losing the general integer math test by a wide margin.

The Verdict

The data points to two very different buyers. The Intel Core 7 253PQE is for workloads where integer math, data compression, and physics calculations are paramount. Its 49.5% lead in integer math and 24% lead in data compression are massive margins that would translate to faster compile times, better database operations, and quicker scientific computing tasks. The 9.4% multithread win and 13.9% random string sorting win reinforce this. The higher boost clock (5.70 GHz) and larger L3 cache (33 MB) appear to drive these wins. The 125-watt TDP and desktop socket indicate a stationary, power-unconstrained environment.

The Intel Core Ultra 5 245HX is the better choice for rendering, cryptography, and single-threaded application response. Its 3% lead across all Cinebench versions, including R23 multi-core at 32358, shows a stronger rendering engine despite fewer threads. The 15% encryption lead and 42.6% prime number win suggest architectural improvements in the Arrow Lake core that benefit specific algorithms. The 12.8% floating point lead and 2.1% single-thread win make it a better all-around mobile processor for mixed workloads. The 55-watt TDP and BGA socket confirm its mobile intent, offering similar or better rendering performance than the desktop part while consuming significantly less power. The average benchmark score difference (55919 vs. 48287) is notable, but it is driven by the Core 7's overwhelming integer wins, not overall superiority. The recorded data indicates the Ultra 5 245HX is the more versatile processor for general use, while the Core 7 253PQE is a specialized integer workhorse.
