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

Head-to-Head Benchmarks

The recorded benchmark data shows a clear overall winner in raw performance terms: the Intel Core Ultra 5 235T takes 14 of the 17 head-to-head comparisons, while the Intel Core 7 251TE wins 3. However, the margins tell a more nuanced story than the win count alone.

Starting with the Cinebench suite, the Core Ultra 5 235T edges ahead consistently but by narrow margins. In Cinebench R15 multicore, it scores 2644 against the Core 7 251TE's 2572, a 2.7% advantage. The single-core R15 result is similar, 373 versus 362, a 2.9% delta. Moving to R20, the pattern holds: 11017 versus 10717 in multicore (2.7% ahead) and 1555 versus 1512 in single-core (2.8% ahead). The R23 results repeat this exactly, with the Ultra 5 leading 26232 to 25518 in multicore and 3703 to 3602 in single-core, both 2.7% gaps. These are consistent, modest wins across the entire Cinebench range.

The Passmark multithread test follows the same trend, with the Ultra 5 scoring 30918 versus 30022, a 2.9% lead. Passmark physics also favors the Ultra 5, 2157 to 1938, a 10.2% margin. The single-thread Passmark tests show a much larger gap: the Ultra 5 scores 4339 against the Core 7's 3568, a 17.8% advantage. This is the single biggest single-threaded performance difference recorded between the two parts.

The Core 7 251TE's wins are concentrated in specific workloads. The largest is Passmark integer math, where it delivers 125739 versus 84244, a massive 49.3% lead. Data compression also goes to the Core 7, 334399 to 295100, a 13.3% margin. Random string sorting is the third win, 39643 to 35377, a 12.1% advantage. These three victories share a common theme: they are throughput-oriented tasks that appear to benefit from the Core 7's higher core and thread counts.

The remaining Passmark tests split heavily toward the Ultra 5. Extended instructions show a 26.9% lead for the Ultra 5, 23212 versus 16974. Floating point math goes to the Ultra 5 by 19.7%, 106546 to 85607. Find prime numbers shows a dramatic 56% advantage for the Ultra 5, 318 to 140.

Architecture Differences

The two processors come from different Intel design families. The Core 7 251TE is based on the Bartlett Lake codename, while the Core Ultra 5 235T uses Arrow Lake-S. These represent separate generations: Core 7 (Bartlett Lake) versus Ultra 5 (Arrow Lake). The process nodes differ substantially, with the Core 7 built on a 10 nm process at Intel's foundry, while the Ultra 5 uses a 3 nm process fabricated by TSMC. The Ultra 5's die size is 243 mm² with 17,800 million transistors, whereas the Core 7's die is 215 mm².

Cache organization diverges as well. The Core 7 provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 36 MB of shared L3. The Ultra 5 uses 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The larger per-core L1 and L2 on the Ultra 5 likely contributes to its single-thread advantage, while the Core 7's larger shared L3 pool may help in certain multi-threaded workloads.

Memory support differs: the Core 7 supports both DDR4 and DDR5, while the Ultra 5 supports DDR5 only. Both use dual-channel memory buses, but the Ultra 5 has a higher memory bandwidth rating at 102.4 GB/s versus 89.6 GB/s for the Core 7. ECC memory is supported on the Core 7 but not on the Ultra 5.

PCIe configuration also differs. The Core 7 offers Gen 5 with 16 lanes (CPU only), while the Ultra 5 offers Gen 5 with 20 lanes (CPU only). Integrated graphics differ as well: the Core 7 uses UHD Graphics 770, while the Ultra 5 uses Arc Xe-LPG Graphics 24EU.

The socket platforms are incompatible. The Core 7 uses Intel Socket 1700, while the Ultra 5 uses Intel Socket 1851. Both are desktop market segments with active production status. Neither processor has an unlocked multiplier.

Specification Differences

The core and thread counts are the most obvious specification gap: the Core 7 251TE delivers 24 cores and 32 threads, while the Core Ultra 5 235T delivers 14 cores and 14 threads. The Core 7 has no hyper-threading overhead in the sense that its 32 threads exceed its core count, while the Ultra 5's thread count equals its core count.

Base clocks differ, with the Core 7 running at 1.40 GHz and the Ultra 5 at 2.20 GHz. Boost clocks reverse this order: the Core 7 boosts to 5.40 GHz, the Ultra 5 to 5.00 GHz. TDP ratings also differ: the Core 7 is rated at 45 watts, the Ultra 5 at 65 watts.

Process node and foundry are different: 10 nm at Intel for the Core 7, 3 nm at TSMC for the Ultra 5. Die size is 215 mm² versus 243 mm². The transistor count is only listed for the Ultra 5 at 17,800 million.

Cache specifications differ across all levels as described above. Memory support, memory bandwidth, ECC support, PCIe lanes, and integrated graphics all differ as previously noted. The launch dates are close: the Core 7 released on 2025-01-12, the Ultra 5 on 2025-01-06. The launch MSRP for the Core 7 is $384, and for the Ultra 5 it is $247.

Where Each One Wins

The Intel Core Ultra 5 235T is the stronger choice for most general computing scenarios based on the data. Its single-thread performance lead of 17.8% in Passmark and consistent 2.7% to 2.9% wins across all Cinebench versions indicate better responsiveness in lightly threaded applications. The Ultra 5 also wins in floating point math, extended instructions, prime number finding, encryption, physics, and the overall multithread Passmark test. Its 86th percentile ranking versus the Core 7's 88th percentile is close, but the Ultra 5's average score of 38561 trails the Core 7's 41650.

The Intel Core 7 251TE wins where raw throughput and integer-heavy workloads dominate. The 49.3% advantage in integer math is substantial, and the 13.3% lead in data compression plus 12.1% in random string sorting suggest workloads involving sorting, compression, or large integer calculations run noticeably better on the Core 7. Its 24 cores and 32 threads provide a structural advantage for highly parallel tasks, even though the Ultra 5 wins the general multithread benchmark by 2.9%.

The Cinebench results, which are often used as a proxy for rendering and 3D workloads, favor the Ultra 5 across the board, albeit by small margins. The Ultra 5 also has higher memory bandwidth (102.4 GB/s versus 89.6 GB/s) and a newer process node, which may explain its efficiency in floating point and encryption tasks.

The Verdict

The benchmark data indicates that the Intel Core Ultra 5 235T is the better processor for users whose workloads resemble the Cinebench suite, Passmark single-thread, floating point math, extended instructions, or encryption. It wins 14 of 17 comparisons, including all six Cinebench tests, and its single-thread Passmark score of 4339 versus 3568 is a decisive margin. Its higher base clock of 2.20 GHz and newer 3 nm TSMC process likely contribute to these results, though the data does not directly measure power efficiency.

The Intel Core 7 251TE is the better choice for integer-heavy, throughput-oriented workloads. The 49.3% integer math advantage and 13.3% data compression lead are the largest margins recorded in either direction. Its 24 cores and 32 threads, combined with 36 MB of shared L3 cache, make it suitable for tasks that scale with core count and benefit from large shared cache. The ECC memory support is an additional differentiator for users requiring error-correcting memory.

Both processors sit in similar competitive positions within their respective classes. The Core 7's nearest rivals are within 0.6% of its average score, while the Ultra 5's nearest rivals are within 0.7%. The Core 7's average benchmark score of 41650 is higher than the Ultra 5's 38561, but the Ultra 5 wins the majority of direct comparisons. The choice ultimately depends on whether the workload aligns with the Ultra 5's strengths in single-thread and floating point performance or the Core 7's strengths in integer throughput and parallel core count.
