Intel Core 7 150U vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The recorded database contains a complete benchmark profile for the Intel Core 7 150U across multiple Cinebench, Geekbench, and Passmark tests. The Intel Core 7 251E has no benchmark scores listed in the database, so a direct numerical comparison between the two parts cannot be established from the available data. The 150U posts a multi-threaded Cinebench R23 score of 8883 and a single-core score of 1875.5. In Geekbench, it records 6234 for multi-core and 1857 for single-core. Passmark results for the 150U include a multi-thread score of 14700, single-thread of 3508, floating point math at 34405, integer math at 51057, and data encryption at 10025. The 251E carries an average benchmark score of 0 in the database, which indicates no measured results are currently available for that processor.

The 150U holds a percentile rank of 71 when compared against all CPUs in the database. Its nearest rivals in the database are the AMD Ryzen 5 4500 with an average score of 17333 and a delta of 0.4 percent, the AMD Ryzen 3 210 also at 17321 with a 0.4 percent delta, the AMD Ryzen 3 PRO 5355GE at 17482 with a negative 0.5 percent delta, and the AMD Ryzen 5 4600G at 17507 with a negative 0.6 percent delta. These deltas are narrow, meaning the 150U sits within a tightly clustered performance band among those desktop-oriented chips. The 251E has no nearest rivals listed and no percentile score beyond 50, which is the neutral baseline for unmeasured parts.

Because the head-to-head benchmark array is empty, the data cannot show which chip wins any specific workload. The only quantitative benchmark information available belongs to the 150U. The 251E is a desktop part with a higher power envelope and more cores, but its actual performance in Cinebench, Geekbench, or Passmark has not been recorded. Therefore, any claim about relative speed between the two would be speculation, not analysis of recorded measurements.

Architecture Differences

The Intel Core 7 150U uses the Raptor Lake architecture, specifically the Raptor Lake-U codename, and belongs to the Core 7 generation built on that microarchitecture. It is manufactured on a 10 nm process node at Intel's foundry. The chip integrates 10 cores and 12 threads, with a base clock of 1.80 GHz and a boost clock of 5.40 GHz. Its thermal design power is 15 watts, placing it firmly in the low-power mobile segment. The 150U uses the Intel BGA 1744 socket, which is a soldered mobile package. Cache allocation includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. Memory support covers DDR4 and DDR5 in a dual-channel configuration, with no ECC support. The integrated graphics are Iris Xe Graphics with 96 execution units. PCIe connectivity is Gen 4 with 8 lanes available from the CPU. The part number is SRMYP, and it was released in January 2024.

The Intel Core 7 251E uses the Bartlett Lake codename and is listed as a Core 7 generation part. Its architecture field is null in the database, but the codename indicates a distinct design from Raptor Lake. It is also manufactured on a 10 nm process node at Intel. The 251E contains 24 cores and 32 threads, a substantially higher count than the 150U. Base clock is 2.10 GHz and boost clock is 5.60 GHz. Thermal design power is 65 watts, which is over four times the 150U's 15-watt envelope and reflects its desktop positioning. The socket is Intel Socket 1700, a desktop platform. Die size is recorded at 257 mm². Cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache, triple the L3 capacity of the 150U. Memory support includes DDR4 and DDR5 with dual-channel operation and a memory bandwidth of 89.6 GB/s. ECC memory is supported on the 251E, a feature absent on the 150U. Integrated graphics are UHD Graphics 770, a different GPU block from the Iris Xe in the 150U. PCIe is Gen 5 with 16 lanes from the CPU, a generation and lane-count advantage over the 150U's Gen 4 with 8 lanes. The market segment is desktop, the production status is active, and the release date is January 2025. The part number is SRQDUQ657. The launch MSRP is $384.

The two processors differ fundamentally in target platform and design goals. The 150U is a mobile processor built for low power consumption and compact systems, while the 251E is a desktop processor built for sustained multi-core throughput with a much larger power budget. The core count difference is the most significant architectural gap: 24 cores versus 10 cores. Thread count follows at 32 versus 12. The 251E also has a larger L2 cache per core (2 MB versus 1.25 MB) and more than double the L3 cache (36 MB versus 12 MB). The 251E supports ECC memory, which the 150U does not. PCIe connectivity is also a clear split: Gen 5 with 16 lanes on the 251E versus Gen 4 with 8 lanes on the 150U. The integrated graphics differ as well, with the 150U using a 96EU Iris Xe design and the 251E using UHD Graphics 770. Both chips share the same 10 nm process node, the same L1 cache size per core, and the same dual-channel DDR4/DDR5 memory support.

The Verdict

The data supports a clear distinction based on platform and workload expectations. The Intel Core 7 150U is the only one of the two with measured benchmark results. Its Cinebench R23 multi-core score of 8883 and single-core score of 1875.5, along with a Geekbench multi-core score of 6234, place it in the 71st percentile of all CPUs in the database. The nearest rival deltas show it is within 0.6 percent of several AMD desktop processors, indicating competitive performance for a 15-watt mobile part.

The Intel Core 7 251E has no benchmark data, so its performance cannot be validated from the database. What is known is its specification sheet: 24 cores, 32 threads, a 5.60 GHz boost clock, 36 MB of L3 cache, ECC support, and Gen 5 PCIe with 16 lanes. These are characteristics of a high-throughput desktop processor, but the database does not confirm how those specifications translate into measured scores.

For users who rely on recorded performance data, the 150U is the only chip with evidence of its capabilities. For users who need the features listed for the 251E, such as ECC memory, a desktop socket, and a much higher core count, the specification sheet alone must suffice, since no benchmark verification exists. The choice between the two is therefore a choice between a measured mobile processor and an unmeasured desktop processor with a larger core configuration.

Where Each One Wins

The Intel Core 7 150U wins in the category of measured performance. Every benchmark score in the database belongs to this chip. It demonstrates strong multi-threaded output for its power class, with a Cinebench R23 multi-core result of 8883 and a Passmark multi-thread score of 14700. Its single-thread performance is also recorded, showing a Cinebench R23 single-core score of 1875.5 and a Passmark single-thread score of 3508. The 150U also has the advantage of being a mobile part with a 15-watt TDP, which suits systems where power consumption and heat generation are primary constraints. Its Iris Xe Graphics with 96 execution units provide a more substantial integrated GPU configuration than the 251E's UHD Graphics 770, at least in terms of execution unit count, though no graphics benchmarks are recorded for either chip.

The Intel Core 7 251E wins in the category of specification-driven capability. It offers more than double the core count at 24 cores, a higher thread count at 32, a faster base clock at 2.10 GHz, and a faster boost clock at 5.60 GHz. Its 36 MB L3 cache and 2 MB per-core L2 cache indicate a design aimed at larger working sets and heavily threaded workloads. ECC memory support makes it suitable for environments where data integrity is a requirement. The Gen 5 PCIe interface with 16 lanes provides more bandwidth for expansion devices compared to the 150U's Gen 4 with 8 lanes. The desktop socket and 65-watt TDP allow for sustained operation under load, whereas the 150U's 15-watt envelope is optimized for battery life and low thermal output.

For workloads that depend on measured multi-core throughput, the 150U has the only available data, and it performs respectably relative to its nearest rivals, all of which are within a 0.6 percent delta. For workloads that demand the raw specifications of the 251E, the absence of benchmark scores means no quantitative confirmation exists in the database. The 150U is the recommended choice when the priority is a mobile form factor with verified performance. The 251E is the choice when the priority is a desktop platform with ECC support, a high core count, and the latest PCIe generation, accepting that its performance remains unmeasured in the database.
