Architecture Differences

The Intel Core 7 251TE is built on the Bartlett Lake architecture and belongs to the Core 7 (Bartlett Lake) generation. It uses a 10 nm process node fabricated by Intel, with a die size of 215 mm². The Intel Processor U301L is based on the Raptor Lake architecture, specifically the Raptor Lake-PS codename, and belongs to the Intel Processor (Raptor Lake) generation. It also uses a 10 nm process node from Intel, but its die size is not recorded in the database.

Cache hierarchies differ substantially. The Intel Core 7 251TE has an L1 cache of 80 KB per core, an L2 cache of 1.25 MB per core, and a shared L3 cache of 36 MB. The Intel Processor U301L has the same per-core L1 and L2 cache sizes, 80 KB per core and 1.25 MB per core respectively, but its shared L3 cache is only 8 MB. This represents a 28 MB difference in total L3 capacity, which directly impacts how much data each processor can hold close to the cores for rapid access.

The integrated graphics units differ. The Intel Core 7 251TE uses UHD Graphics 770, while the Intel Processor U301L uses UHD Graphics 64EU. The market segment also differs: the Core 7 251TE is classified as a Desktop processor, while the U301L is classified as Mobile. Both processors are currently listed as Active in production status. The Core 7 251TE was released on 2025-01-12, while the U301L was released earlier on 2024-04-07. Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Intel Core 7 251TE and the Intel Processor U301L. The benchmark array for the U301L is empty, and the headToHeadBenchmarks field contains no entries. Therefore, a direct comparison using identical test runs is not possible from the recorded data.

However, the Intel Core 7 251TE has extensive benchmark data available. In Cinebench R15, it scores 2572 in multicore and 362 in singlecore. In Cinebench R20, it scores 10717 in multicore and 1512 in singlecore. In Cinebench R23, it scores 25518 in multicore and 3602 in singlecore. The PassMark suite shows a multithread score of 30022, a single-thread score of 3568, integer math at 125739, floating point math at 85607, data compression at 334399, data encryption at 22176, extended instructions at 16974, find prime numbers at 140, random string sorting at 39643, and physics at 1938.

The Intel Processor U301L has no recorded benchmark scores in the database, so no wins can be assigned to either processor in a head-to-head context. The winsA and winsB fields are both zero. The Intel Core 7 251TE holds an average benchmark score of 41650 and sits in the 88th percentile among all CPUs. The U301L has an average benchmark score of 0 and sits in the 50th percentile, though this percentile is based on its classification rather than measured performance data.

The Core 7 251TE's nearest rivals in the database provide context for its performance tier. It sits 0.1% above the Intel Core Ultra 7 265H, 0.2% above the Intel Core i7-14650HX, 0.3% below the Intel Core i7-12850HX, and 0.6% below the Intel Core i7-14700T. These are all processors in a similar average score range, from 41576 to 41914. The U301L has no nearest rivals listed.

Both processors share the same L1 cache size of 80 KB per core, the same L2 cache size of 1.25 MB per core, dual-channel memory support, DDR4 and DDR5 memory support, the Intel Socket 1700, the 10 nm process node, the Intel foundry, and a locked multiplier. Both are currently Active in production.

The Core 7 251TE has a significantly higher boost clock, 5.40 GHz versus 2.20 GHz for the U301L, and a higher base clock, 1.40 GHz versus 1.20 GHz. The difference in L3 cache is notable: 36 MB versus 8 MB. The Core 7 251TE also supports PCIe Gen 5 with 16 lanes, while the U301L is limited to PCIe Gen 4 with 8 lanes.

Where Each One Wins

The Intel Core 7 251TE wins on every measurable performance dimension in the database. It offers 24 cores versus 5, 32 threads versus 6, a 5.40 GHz boost clock versus 2.20 GHz, and a 36 MB L3 cache versus 8 MB. Its Cinebench R23 multicore score of 25518 indicates strong parallel throughput, and its PassMark multithread score of 30022 confirms this. The data compression score of 334399 and integer math score of 125739 position it well for workloads that scale across many threads, such as rendering, encoding, and compilation.

The Intel Processor U301L wins on power efficiency. Its 15 W TDP is one-third of the Core 7 251TE's 45 W TDP. This makes it suitable for thermally constrained or battery-powered systems. Its market segment is Mobile, while the Core 7 251TE is Desktop, so the U301L is positioned for low-power mobile deployments. It also has a lower launch MSRP of $107, compared to $384 for the Core 7 251TE, though both figures are stated once here for reference.

The Core 7 251TE's 88th percentile ranking among all CPUs places it well above the U301L's 50th percentile. The Core 7 251TE's average benchmark score of 41650 is substantially higher than the U301L's recorded average of 0, which reflects the absence of benchmark data for the U301L rather than a literal zero-performance result. For applications that require heavy multi-threading, high clock speeds, large cache capacity, or ECC memory support, the Core 7 251TE is the clear choice from the data. For applications that prioritize low power draw, the U301L's 15 W TDP gives it an advantage.

The Verdict

The Intel Core 7 251TE is the stronger processor in nearly every recorded specification. It provides 24 cores, 32 threads, a 5.40 GHz boost clock, 36 MB of L3 cache, PCIe Gen 5 support, ECC memory support, and a 45 W TDP. Its benchmark scores place it in the 88th percentile among all CPUs, with an average score of 41650. The Cinebench R23 multicore score of 25518 and PassMark multithread score of 30022 confirm its capability for demanding parallel workloads. Its nearest rivals, the Intel Core Ultra 7 265H, Core i7-14650HX, Core i7-12850HX, and Core i7-14700T, all sit within 0.6% of its average score, indicating it competes at a high level in the desktop segment.

The Intel Processor U301L is a much more modest part. With 5 cores, 6 threads, a 2.20 GHz boost clock, 8 MB of L3 cache, PCIe Gen 4 support, and no ECC memory support, it is designed for low-power mobile systems. Its 15 W TDP is the key differentiator, making it suitable for power-constrained environments. It has no recorded benchmark scores, which limits direct performance comparison, but its specification profile clearly targets a different use case than the Core 7 251TE.

The data supports a simple split: choose the Intel Core 7 251TE for desktop workloads that benefit from high core counts, high clock speeds, large caches, and ECC memory. Choose the Intel Processor U301L for mobile applications where the 15 W TDP is the primary consideration. The Core 7 251TE is the performance leader in this comparison, while the U301L offers the lowest power draw.
