Intel Core 7 150UL vs Intel Core 7 251TE Comparison

Head-to-Head Benchmarks

The Intel Core 7 251TE delivers substantially higher measured performance across every recorded benchmark in the database. Its average benchmark score of 41,650 places it in the 88th percentile of all CPUs tracked, while the Core 7 150UL has a percentile score of 50 and an average benchmark score of zero, indicating no benchmark results were recorded for that processor.

The 251TE posts a Cinebench R23 multicore score of 25,518, which is the strongest multi-threaded result in its recorded profile. Its single-core Cinebench R23 score of 3,602 shows a balanced capability between lightly threaded and heavily threaded workloads. In Cinebench R20, the 251TE scores 10,717 multicore and 1,512 single-core, while in the older Cinebench R15 test it records 2,572 multicore and 362 single-core.

PassMark results for the 251TE further reinforce its positioning. The multithread score of 30,022 and single-thread score of 3,568 indicate consistent throughput across both parallel and serial tasks. Integer math reaches 125,739, floating point math hits 85,607, and extended instructions score 16,974. Data compression scores 334,399, data encryption scores 22,176, and random string sorting completes at 39,643. Physics processing records 1,938, while prime number finding scores 140.

The nearest rivals in the database help contextualize the 251TE's standing. The Intel Core Ultra 7 265H scores 41,621, which is 0.1% behind the 251TE. The Intel Core i7-14650HX scores 41,576, trailing by 0.2%. The Intel Core i7-12850HX scores 41,779, which is 0.3% ahead of the 251TE, and the Intel Core i7-14700T scores 41,914, leading by 0.6%. This cluster of results shows the 251TE sitting within a narrow competitive band, effectively tied with several strong desktop and mobile processors.

The 150UL has no recorded benchmark scores in the database, so direct numerical comparisons between the two processors cannot be established from measured data. The available information shows a 14-point difference in percentile ranking (50 versus 88), which indicates the 251TE occupies a much higher performance tier among all CPUs in the database.

Architecture Differences

The two processors belong to different architectural families despite sharing the same Intel Socket 1700. The Core 7 150UL is based on the Raptor Lake architecture, specifically the Raptor Lake-PS codename, while the Core 7 251TE uses the Bartlett Lake codename. Both are manufactured on Intel's 10 nm process node and built by Intel's foundry.

Core counts differ considerably. The 150UL has 10 cores and 12 threads, whereas the 251TE has 24 cores and 32 threads. This 14-core and 20-thread difference accounts for the large multicore performance gap expected between the two parts. Base clocks are 1.70 GHz for the 150UL versus 1.40 GHz for the 251TE, but boost clocks reverse the order: the 251TE boosts to 5.40 GHz while the 150UL reaches 5.00 GHz. Thermal design power also differs, with the 150UL rated at 15 watts and the 251TE at 45 watts.

Cache hierarchies share per-core allocations: both have 80 KB of L1 cache per core and 1.25 MB of L2 cache per core. The shared L3 cache, however, is three times larger on the 251TE at 36 MB versus 12 MB on the 150UL. The 251TE also has a recorded die size of 215 mm².

Memory support is identical in type: both support DDR4 and DDR5 in a dual-channel configuration. The 251TE lists a memory bandwidth of 89.6 GB/s, while the 150UL has no bandwidth figure recorded. ECC memory support differs, with the 251TE supporting ECC and the 150UL not supporting it.

PCIe capabilities differ substantially. The 251TE provides Gen 5 with 16 lanes from the CPU, while the 150UL provides Gen 4 with 8 lanes from the CPU. Integrated graphics also differ: the 150UL uses Iris Xe Graphics with 96 execution units, while the 251TE uses UHD Graphics 770.

Release timing shows the 150UL launched on April 7, 2024, while the 251TE launched on January 12, 2025. The 251TE has a recorded launch MSRP of $384 and a part number of SRQAXQ5ZG, while the 150UL has no recorded MSRP or part number. Neither processor has an unlocked multiplier.

The Verdict

The Intel Core 7 251TE is the stronger performer based on recorded data. Its 24 cores, 32 threads, 36 MB of L3 cache, and 5.40 GHz boost clock combine to produce benchmark results that place it in the 88th percentile. The 150UL, with 10 cores, 12 threads, 12 MB of L3 cache, and a 5.00 GHz boost clock, holds a 50th percentile position but has no recorded benchmark scores to verify its real-world standing.

The 251TE's nearest rivals in the database all cluster within 0.6% of its average score, which indicates it performs competitively against well-known desktop processors like the Intel Core i7-14700T and Intel Core i7-12850HX. The 150UL cannot be compared directly through measured benchmarks, but its lower core count, smaller cache, and reduced PCIe capability suggest a more modest performance envelope.

For workloads that benefit from many cores and threads, the 251TE is clearly positioned as the more capable part. Its 36 MB of shared L3 cache and 89.6 GB/s memory bandwidth support data-intensive tasks. The 150UL's 15-watt TDP and smaller footprint make it suitable for lower-power configurations, though no benchmark data confirms its performance level.

Where Each One Wins

The Intel Core 7 251TE wins in every category where recorded data exists. Its 24 cores and 32 threads give it a decisive advantage in multi-threaded workloads such as rendering, compilation, and data processing. The Cinebench R23 multicore score of 25,518 and PassMark multithread score of 30,022 confirm strong parallel throughput. The 36 MB of shared L3 cache and 89.6 GB/s memory bandwidth support workloads that repeatedly access large datasets.

The 251TE also leads in single-thread performance with a Cinebench R23 single-core score of 3,602 and a PassMark single-thread score of 3,568. Its 5.40 GHz boost clock and larger cache hierarchy contribute to this result. The PCIe Gen 5 interface with 16 lanes provides more bandwidth for expansion devices such as graphics cards and NVMe storage compared to the 150UL's Gen 4 with 8 lanes.

ECC memory support on the 251TE makes it suitable for error-sensitive computing environments where data integrity is critical. The 150UL lacks this capability.

The Intel Core 7 150UL holds advantages only in areas unrelated to raw performance. Its 15-watt TDP is one-third of the 251TE's 45-watt rating, which suggests lower power consumption in lightly loaded scenarios. Its 1.70 GHz base clock is higher, which could reduce latency when transitioning from idle states. The Iris Xe Graphics with 96 execution units provides a different integrated graphics option compared to the 251TE's UHD Graphics 770, though neither is a dedicated GPU replacement.

The 150UL's smaller core count and lower TDP make it better suited for compact or thermally constrained desktop builds where space and cooling are limited. The 251TE, with its higher TDP and larger die, requires more substantial cooling but delivers far more compute capability. For users who need maximum throughput from a Socket 1700 processor, the 251TE is the data-backed choice. For users prioritizing low power draw and modest performance demands, the 150UL remains an option, though its lack of recorded benchmarks leaves its actual performance unverified.
