Intel Core 7 251TE vs Intel Core Ultra 5 235HX Comparison

Where Each One Wins

The benchmark data splits these two Intel processors into a clear primary role and a single specialized secondary role. The Intel Core Ultra 5 235HX wins 16 of the 17 recorded head-to-head comparisons, establishing itself as the dominant performer across rendering, encryption, compression, and general multi-threaded workloads. The Intel Core 7 251TE wins exactly one test: PassMark integer math, where it leads by 29.4%. That single victory, however, is substantial enough to define a narrow niche.

The Core Ultra 5 235HX excels in every Cinebench test, which measures both multi-core and single-core rendering capability. Its multi-core scores in Cinebench R23 (34731) and R20 (14587) are roughly 36% higher than the Core 7 251TE's corresponding results. Single-core performance also favors the Ultra 5, with a Cinebench R23 single-core score of 4903 versus 3602. This pattern repeats across PassMark's data compression, encryption, extended instructions, prime number finding, floating point math, multithread, physics, random string sorting, and single-thread tests.

For users whose workloads primarily involve integer arithmetic, the Core 7 251TE offers a measurable advantage. Its PassMark integer math score of 125739 exceeds the Ultra 5's 97177 by 29.4%. This is the only metric where the 251TE's higher core count (24 versus 14) translates into a clear win, likely reflecting the efficiency of its core arrangement for that specific instruction pattern. Outside that test, the Ultra 5's architectural advantages consistently overcome the core count difference.

The percentile rankings reflect this overall dominance: the Core Ultra 5 235HX sits at the 91st percentile among all CPUs in the database, while the Core 7 251TE is at the 88th. The average benchmark scores tell the same story, with the Ultra 5 averaging 52073 and the 251TE averaging 41650.

Head-to-Head Benchmarks

The most consistent pattern in the head-to-head data is the 26.5% delta that repeats across all six Cinebench tests. The Core Ultra 5 235HX scores 3500 vs 2572 in Cinebench R15 multi-core, 494 vs 362 in R15 single-core, 14587 vs 10717 in R20 multi-core, 2059 vs 1512 in R20 single-core, 34731 vs 25518 in R23 multi-core, and 4903 vs 3602 in R23 single-core. The uniformity of this 26.5% gap suggests a fundamental architectural efficiency advantage rather than a workload-specific quirk.

The largest margin in either direction appears in PassMark extended instructions, where the Core Ultra 5 235HX scores 34808 versus the Core 7 251TE's 16974, a 51.2% advantage. This is followed closely by PassMark find prime numbers, where the Ultra 5 leads by 61.2% (361 vs 140). These two tests highlight the Ultra 5's superior throughput for specialized instruction sets and algorithmic workloads.

PassMark data encryption shows a 32.2% gap (32697 vs 22176), while floating point math shows a 34.1% difference (129819 vs 85607). The Ultra 5 also leads by 24% in PassMark physics (2550 vs 1938), by 21.6% in data compression (426417 vs 334399), and by 22.2% in random string sorting (50929 vs 39643). The multithread test shows a 26.5% gap (40849 vs 30022), matching the Cinebench pattern.

The single counter-example is PassMark integer math. The Core 7 251TE scores 125739, which is 29.4% higher than the Ultra 5's 97177. This is the only test where the 251TE's 24-core configuration outperforms the Ultra 5's 14 cores.

Specification Differences

The two processors differ across nearly every core specification. The Core 7 251TE has 24 cores and 32 threads, while the Core Ultra 5 235HX has 14 cores and 14 threads. The 251TE's base clock is 1.40 GHz with a boost clock of 5.40 GHz; the Ultra 5 runs at 2.90 GHz base and 5.10 GHz boost. The 251TE has a 45 W TDP, the Ultra 5 has a 55 W TDP.

Memory support diverges: the 251TE supports both DDR4 and DDR5, while the Ultra 5 supports only DDR5. Both use dual-channel memory, but the memory bandwidth differs: 89.6 GB/s for the 251TE versus 102.4 GB/s for the Ultra 5. ECC memory is supported on the 251TE but not on the Ultra 5.

PCIe lane counts also differ, with the 251TE providing Gen 5, 16 lanes (CPU only) and the Ultra 5 providing Gen 5, 20 lanes (CPU only). The integrated graphics are different as well: the 251TE has UHD Graphics 770, while the Ultra 5 has Arc Xe-LPG Graphics 48EU. The 251TE has a locked multiplier; the Ultra 5 is multiplier unlocked. The 251TE has a launch MSRP of $384; the Ultra 5 has no recorded launch MSRP.

Architecture Differences

The Core 7 251TE is built on the Bartlett Lake architecture using Intel's 10 nm process with a die size of 215 mm². The Core Ultra 5 235HX uses the Arrow Lake architecture (codename Arrow Lake-HX) on TSMC's 3 nm process with a die size of 243 mm² and 17,800 million transistors. The 3 nm process node gives the Ultra 5 a significant density and efficiency advantage, which shows in its benchmark performance despite having fewer cores.

Cache configurations differ substantially. The 251TE has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 36 MB of shared L3 cache. The Ultra 5 has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The Ultra 5's larger per-core L1 and L2 caches likely contribute to its strong single-core performance, while the 251TE's larger L3 pool supports its higher core count.

The market segments differ: the 251TE is a desktop processor on Intel Socket 1700, while the Ultra 5 is a mobile processor on Intel BGA 2114. The socket difference alone means these are not interchangeable in any system. The Ultra 5's Arrow Lake-HX codename indicates its high-performance mobile positioning, while Bartlett Lake targets desktop deployments.

Both processors were released on the same date and are marked as Active in production status. The Ultra 5 belongs to the Core Ultra Series 2 family, while the 251TE does not have a series designation listed.

The Verdict

The benchmark data indicates the Intel Core Ultra 5 235HX is the stronger processor in nearly every measurable workload. It wins 16 of 17 head-to-head comparisons, including all six Cinebench tests, all PassMark encryption and compression tests, and all but one of the PassMark math and sorting tests. Its average benchmark score of 52073 places it 25% above the Core 7 251TE's 41650. The 91st percentile ranking versus the 88th confirms its overall position in the database.

The Core 7 251TE's single winning metric, PassMark integer math at 125739 versus 97177, gives it a clear niche for integer-heavy applications. Its 24-core, 32-thread configuration also offers more parallel threads for workloads that scale with thread count, even though the Ultra 5's architecture delivers higher throughput per thread across most tests.

Users who need ECC memory support and a desktop socket with DDR4 or DDR5 compatibility will find the 251TE suitable. Users who prioritize raw performance across rendering, encryption, physics, and general compute should select the Ultra 5. The Ultra 5 also provides more PCIe lanes (20 versus 16) and higher memory bandwidth (102.4 GB/s versus 89.6 GB/s). For mobile deployments requiring the highest available compute density, the Ultra 5's 3 nm process and unlocked multiplier make it the data-supported choice.
