Intel Core 7 251TE vs Intel Core Ultra 7 155HL Comparison

Intel Core 7 251TE vs Intel Core Ultra 7 155HL

The Intel Core 7 251TE and Intel Core Ultra 7 155HL are both active desktop processors from Intel, but they represent distinct design philosophies and performance tiers. The Core 7 251TE, built on the Bartlett Lake architecture with a 10 nm process, offers 24 cores and 32 threads, while the Core Ultra 7 155HL, based on Meteor Lake with a 7 nm process, provides 16 cores and 22 threads. Benchmark data from the database shows a substantial performance gap between the two, with the Core 7 251TE posting an average benchmark score of 41650 and ranking in the 88th percentile of all CPUs, while the Core Ultra 7 155HL has no recorded benchmark scores and sits in the 50th percentile. This disparity in measured performance forms the foundation of the comparison.

Head-to-Head Benchmarks

The database does not include direct head-to-head benchmark results for these two processors. Instead, the analysis relies on the recorded scores for the Core 7 251TE and the absence of scores for the Core Ultra 7 155HL. The Core 7 251TE delivers strong multi-threaded performance, as indicated by its Cinebench R23 multicore score of 25518 and Cinebench R20 multicore score of 10717. Single-thread performance is also notable, with Cinebench R23 single-core scoring 3602 and Cinebench R15 single-core scoring 362. PassMark results further illustrate the processor's capabilities: integer math scores 125739, floating point math scores 85607, and multithread score reaches 30022. Data compression, a common workstation workload, scores 334399, while encryption and extended instructions register 22176 and 16974, respectively. Random string sorting completes at 39643, and find prime numbers scores 140.

The Core Ultra 7 155HL, however, has no benchmark entries in the database. This absence means that no direct comparison of individual test scores is possible. The Core 7 251TE's nearest rivals, as recorded in the database, include the Intel Core Ultra 7 265H with an average score of 41621 and a delta of 0.1 percent, the Intel Core i7-14650HX at 41576 with a delta of 0.2 percent, the Intel Core i7-12850HX at 41779 with a delta of -0.3 percent, and the Intel Core i7-14700T at 41914 with a delta of -0.6 percent. These figures show the Core 7 251TE performing within a narrow band of these comparable processors, slightly ahead of the Core Ultra 7 265H and Core i7-14650HX, and slightly behind the Core i7-12850HX and Core i7-14700T. The margins are small, all under one percent, indicating that the Core 7 251TE competes closely with these established parts.

In contrast, the Core Ultra 7 155HL lacks any rival data, and its average benchmark score is recorded as zero. This does not imply the processor is incapable, but rather that the database has not captured performance measurements for it. The percentile ranking of 50 places it at the median of all CPUs, which is a default or unmeasured position rather than a tested outcome. Therefore, the head-to-head comparison is one-sided: the Core 7 251TE has a rich set of benchmark results, while the Core Ultra 7 155HL has none. The data indicates that the Core 7 251TE is the only one of the two with verified performance numbers, and those numbers position it in the upper tier of processors, above the 88th percentile of all CPUs.

Architecture Differences

The two processors diverge significantly in their underlying architectures. The Intel Core 7 251TE uses the Bartlett Lake codename and belongs to the Core 7 generation, fabricated on a 10 nm process node at Intel's foundry. Its die size is recorded as 215 mm². The Core Ultra 7 155HL, meanwhile, uses the Meteor Lake architecture with the Meteor Lake-PS codename, belongs to the Ultra 7 generation, and is built on a 7 nm process, also at Intel. No die size is recorded for the Core Ultra 7 155HL.

Core and thread counts differ markedly. The Core 7 251TE has 24 cores and 32 threads, while the Core Ultra 7 155HL has 16 cores and 22 threads. Cache hierarchies also differ. The Core 7 251TE has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 36 MB of shared L3 cache. The Core Ultra 7 155HL has larger per-core caches, with 112 KB of L1 per core and 2 MB of L2 per core, but a smaller shared L3 cache at 24 MB. This means the Core 7 251TE offers more total L3 cache, which can benefit workloads that rely on large shared data sets, while the Core Ultra 7 155HL provides more L1 and L2 per core, which can reduce latency for per-thread data.

Clock speeds show a similar pattern. Both processors have the same base clock of 1.40 GHz, but the boost clock differs: the Core 7 251TE reaches 5.40 GHz, while the Core Ultra 7 155HL tops out at 4.80 GHz. This higher boost clock on the Core 7 251TE contributes to its stronger single-thread performance scores, such as the Cinebench R23 single-core result of 3602. The Core Ultra 7 155HL's lower boost clock suggests a more modest single-thread ceiling.

Memory support and PCIe capabilities also differ. The Core 7 251TE supports both DDR4 and DDR5 memory, while the Core Ultra 7 155HL supports DDR5 only, with the note that memory support depends on the motherboard. Both use dual-channel memory buses and have the same memory bandwidth of 89.6 GB/s. The Core 7 251TE supports ECC memory, while the Core Ultra 7 155HL does not. For PCIe, the Core 7 251TE provides Gen 5 with 16 lanes from the CPU, while the Core Ultra 7 155HL provides Gen 4 with 8 lanes from the CPU. This gives the Core 7 251TE a clear advantage in PCIe bandwidth and connectivity options.

Integrated graphics differ as well. The Core 7 251TE uses UHD Graphics 770, while the Core Ultra 7 155HL uses Arc Xe-LPG 128EU. Both are integrated solutions, but they represent different generations and capabilities, with the Arc Xe-LPG likely offering more modern features given its placement in the Ultra 7 series. Sockets also differ: the Core 7 251TE uses Intel Socket 1700, while the Core Ultra 7 155HL uses Intel Socket 1851, which means they are not interchangeable on the same motherboard.

Where Each One Wins

The Intel Core 7 251TE wins in nearly every measurable category due to its superior specifications and verified benchmark results. Its 24 cores and 32 threads give it a clear advantage in multi-threaded workloads, as evidenced by the Cinebench R23 multicore score of 25518 and PassMark multithread score of 30022. The higher boost clock of 5.40 GHz supports strong single-thread performance, with Cinebench R23 single-core reaching 3602. The larger 36 MB L3 cache benefits workloads that use large shared data sets, such as database operations or content creation applications. ECC memory support makes it suitable for workstations that require error correction for data integrity. PCIe Gen 5 with 16 lanes provides higher bandwidth for GPUs and NVMe drives, which is advantageous for high-end desktop builds. The processor's benchmark scores place it in the 88th percentile of all CPUs, and its nearest rivals, all within a 0.6 percent delta, confirm it is a competitive part in its segment.

The Intel Core Ultra 7 155HL has no recorded benchmark wins because the database contains no performance data for it. However, its specifications point to some areas of potential strength. The larger L1 and L2 caches per core (112 KB and 2 MB, respectively) could provide lower latency for per-thread data, which may benefit certain latency-sensitive workloads. The 7 nm process node is more advanced than the 10 nm node of the Core 7 251TE, potentially offering better power efficiency, though both have the same 45 watt TDP. The Arc Xe-LPG 128EU integrated graphics is a more modern integrated solution compared to UHD Graphics 770, which could be useful for systems without a discrete GPU. The Core Ultra 7 155HL also has a lower launch MSRP of $438, though pricing is not a factor in performance analysis. Its release date of April 2024 is earlier than the Core 7 251TE's January 2025, indicating it is a more established product in the market.

In practical terms, the Core 7 251TE is the better choice for compute-heavy tasks, such as rendering, compiling, or scientific simulations, based on its core count, cache size, and verified benchmark scores. The Core Ultra 7 155HL may appeal to systems that prioritize integrated graphics performance or per-core cache efficiency, but without benchmark data, its actual performance cannot be quantified. The database clearly favors the Core 7 251TE in this comparison, with a substantial specification lead and a full suite of measured results that place it in the upper percentile of CPUs.
