Intel Core 7 253PTE vs Intel Core Ultra 9 285HX Comparison

The Verdict

The benchmark data is unambiguous: the Intel Core Ultra 9 285HX is the dominant processor in this comparison, winning 16 of 17 head-to-head tests. The Core 7 253PTE takes a single victory, in Cinebench R23 single-core, where it leads by 37.3%. The Ultra 9 285HX also sits at the 95th percentile of all CPUs in the database, while the Core 7 253PTE ranks at the 84th percentile. The average benchmark score gap is substantial: 76,155 for the Ultra 9 285HX versus 34,962 for the Core 7 253PTE. The Ultra 9 285HX is the choice for any workload that scales with core count, memory bandwidth, or sustained multithreaded throughput. The Core 7 253PTE appeals only to the narrow use case where its single-core Cinebench R23 result matters more than everything else, and where the desktop Socket 1700 platform is a requirement.

Architecture Differences

The two processors come from different Intel design lines. The Core 7 253PTE uses the Bartlett Lake codename, built on Intel's 10 nm process, and is classified as a desktop part. The Core Ultra 9 285HX uses the Arrow Lake architecture, specifically Arrow Lake-HX, built on a 3 nm process at TSMC, and is a mobile part. The Ultra 9 285HX contains 17,800 million transistors on a 243 mm² die. The Core 7 253PTE has no transistor or die size figures in the database.

Core and thread counts diverge sharply. The Core 7 253PTE has 10 cores and 20 threads, indicating hyperthreading support. The Core Ultra 9 285HX has 24 cores and 24 threads, meaning no hyperthreading. Despite the lack of simultaneous multithreading, the Ultra 9's additional 14 physical cores give it a massive parallel advantage. Base clocks are 1.80 GHz for the Core 7 253PTE and 2.80 GHz for the Ultra 9 285HX. Boost clocks are close: 5.40 GHz versus 5.50 GHz.

Cache hierarchies also differ. The Core 7 253PTE has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Ultra 9 285HX has 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The Ultra 9 leads in every cache level. Memory support differs as well: the Core 7 253PTE supports DDR4 and DDR5, while the Ultra 9 285HX supports DDR5 only. Both are dual-channel. Memory bandwidth is 89.6 GB/s for the Core 7 253PTE versus 102.4 GB/s for the Ultra 9 285HX. Both support ECC memory. PCIe connectivity differs: the Core 7 253PTE has Gen 5 with 16 CPU lanes, the Ultra 9 285HX has Gen 5 with 20 CPU lanes.

Integrated graphics are not equal. The Core 7 253PTE uses UHD Graphics 730. The Ultra 9 285HX uses Arc Xe-LPG Graphics 64EU, a more capable GPU. The Core 7 253PTE is socketed (Intel Socket 1700), while the Ultra 9 285HX is a BGA 2114 mobile package. The Core 7 253PTE has a locked multiplier; the Ultra 9 285HX has an unlocked multiplier. The Core 7 253PTE launched with a $384 MSRP on 2026-03-08. The Ultra 9 285HX launched on 2025-01-12 with no MSRP recorded.

Where Each One Wins

The Core Ultra 9 285HX wins in every multithreaded category. Cinebench R15 multicore is 5656.5 versus 2144, a 62.1% advantage. Cinebench R20 multicore is 20236 versus 8935, a 55.8% lead. Cinebench R23 multicore is 36429.5 versus 21276, a 41.6% margin. PassMark multithread is 56902 versus 25031, a 56% lead. PassMark physics is 3476 versus 1318, a 62.1% advantage. The Ultra 9 also wins all integer, floating point, encryption, compression, instruction, and sorting workloads. PassMark data encryption shows a 68.1% lead, extended instructions a 65.2% lead, floating point math a 65.5% lead, and random string sorting a 63.4% lead. Find prime numbers is the largest gap: 460 versus 82, an 82.2% deficit for the Core 7 253PTE.

Single-thread performance is split. The Ultra 9 285HX wins PassMark single-thread by 17.8% (4618 versus 3794) and Cinebench R15 single-core by 6.6% (323.5 versus 302). The Core 7 253PTE wins Cinebench R20 single-core by 55.8% (2856 versus 1261) and Cinebench R23 single-core by 37.3% (3003 versus 2187.5). This creates a peculiar pattern: the Core 7 253PTE shows very strong results in newer Cinebench single-core tests, while the Ultra 9 285HX leads in the legacy R15 single-core test and in PassMark single-thread. The practical interpretation is that the Core 7 253PTE has excellent single-core burst performance in Cinebench's modern rendering pipeline, while the Ultra 9 285HX is better in other single-threaded measures.

For integer math, the Ultra 9 wins but by the smallest margin of any multithreaded test: 155076 versus 119552, a 22.9% lead. This suggests the Core 7 253PTE is relatively stronger in integer work than in floating point or encryption, though still behind.
