Intel Core 7 251TE vs Intel Processor U300L Comparison

The Verdict

The database comparison between the Intel Core 7 251TE and the Intel Processor U300L shows two processors aimed at entirely different segments. The Core 7 251TE is a desktop part with 24 cores, 32 threads, and a boost clock of 5.40 GHz, placing it in the 88th percentile of all CPUs. The U300L is a mobile part with 5 cores, 6 threads, and a boost clock of 4.40 GHz, sitting in the 50th percentile. The data indicates that the Core 7 251TE is the clear choice for workloads requiring substantial parallel processing, while the U300L serves situations where lower power consumption and a smaller footprint take priority.

The Core 7 251TE has a TDP of 45 watts compared to 15 watts for the U300L, confirming that the former draws three times the power budget. This is not a direct fight in the same class. The Core 7 251TE belongs on a desktop motherboard with Socket 1700 and PCIe Gen 5 support, while the U300L targets mobile systems with the same socket but PCIe Gen 4 and 8 lanes. The data shows no benchmark results for the U300L in the database, so the comparison relies on specifications and the Core 7 251TE's recorded scores.

From the recorded measurements, the Core 7 251TE delivers Cinebench R23 multi-core at 25518 and single-core at 3602. The U300L has no recorded scores in the database, so the analysis must rest on the architectural differences and the Core 7 251TE's percentile placement. The Core 7 251TE is the appropriate selection for anyone assembling a desktop system with heavy compute demands. The U300L is the appropriate selection for a low-power mobile or compact system where the 45-watt TDP of the Core 7 251TE would be excessive.

Where Each One Wins

The Core 7 251TE wins in every measurable category because the database contains no benchmark entries for the U300L. The Core 7 251TE shows a PassMark multi-thread score of 30022, a PassMark single-thread score of 3568, and a PassMark data encryption score of 22176. These numbers indicate strong performance in multi-threaded rendering, integer math, and encryption workloads. The PassMark integer math score of 125739 and floating point math score of 85607 further reinforce the Core 7 251TE's capability in compute-heavy tasks.

The U300L wins only in power efficiency and market positioning. Its 15-watt TDP allows deployment in thermally constrained environments, and its mobile segment classification suggests it is designed for systems where the 45-watt TDP of the Core 7 251TE would require more substantial cooling. The U300L has a boost clock of 4.40 GHz, which is lower than the 5.40 GHz of the Core 7 251TE, but the U300L can still handle single-threaded tasks at a reasonable level given its architecture.

The Core 7 251TE shows a Cinebench R20 multi-core score of 10717 and a Cinebench R15 multi-core score of 2572. These results place it near rivals such as the Intel Core Ultra 7 265H, which has an average score of 41621 and a delta of 0.1 percent, and the Intel Core i7-14650HX, with an average score of 41576 and a delta of 0.2 percent. The Core 7 251TE also sits within 0.3 percent of the Intel Core i7-12850HX and 0.6 percent of the Intel Core i7-14700T. This clustering indicates that the Core 7 251TE performs competitively with these established desktop and mobile processors.

Architecture Differences

The Core 7 251TE uses the Bartlett Lake codename and belongs to the Core 7 generation, while the U300L uses the Raptor Lake architecture with the Raptor Lake-PS codename. Both processors are built on a 10 nm process node at Intel's foundry, but the similarities end there. The Core 7 251TE has 24 cores and 32 threads, while the U300L has 5 cores and 6 threads. This difference in core count is the primary architectural separator.

The cache hierarchy differs significantly. The Core 7 251TE has 36 MB of shared L3 cache, while the U300L has 8 MB of shared L3 cache. Both processors use 80 KB of L1 cache per core and 1.25 MB of L2 cache per core. The larger L3 cache on the Core 7 251TE helps with data-heavy workloads, particularly when multiple cores access shared data.

Memory support is similar in type: both support DDR4 and DDR5 with dual-channel memory buses. The Core 7 251TE has a recorded memory bandwidth of 89.6 GB/s, while the U300L has no bandwidth figure in the database. The Core 7 251TE supports ECC memory, while the U300L does not. This makes the Core 7 251TE suitable for error-sensitive workloads such as data processing and server-like applications.

The PCIe configuration differs as well. The Core 7 251TE uses PCIe Gen 5 with 16 lanes (CPU only), while the U300L uses PCIe Gen 4 with 8 lanes (CPU only). The integrated graphics also differ: the Core 7 251TE has UHD Graphics 770, while the U300L has UHD Graphics 48EU. The Core 7 251TE has a die size of 215 mm², while the U300L has no recorded die size.

Head-to-Head Benchmarks

The database has no head-to-head benchmark entries for these two processors, and the U300L has no recorded scores in any test. The comparison therefore relies on the Core 7 251TE's absolute scores and its position relative to nearby rivals.

The Core 7 251TE records a Cinebench R23 multi-core score of 25518 and a single-core score of 3602. In Cinebench R20, the multi-core score is 10717 and the single-core score is 1512. In Cinebench R15, the multi-core score is 2572 and the single-core score is 362. These scores show strong scaling from R15 through R23, with the multi-core results benefiting from the 24-core configuration.

PassMark results for the Core 7 251TE include a multi-thread score of 30022, a single-thread score of 3568, an integer math score of 125739, a floating point math score of 85607, a data compression score of 334399, a data encryption score of 22176, an extended instructions score of 16974, a physics score of 1938, a random string sorting score of 39643, and a find prime numbers score of 140. The data compression score of 334399 stands out as the highest single result, indicating strong performance in compression workloads. The find prime numbers score of 140 is the lowest, reflecting the limitations of integer prime calculations even with 24 cores.

The average benchmark score for the Core 7 251TE is 41650, placing it in the 88th percentile of all CPUs. Its nearest rivals are the Intel Core Ultra 7 265H with an average score of 41621 (0.1 percent lower), the Intel Core i7-14650HX with 41576 (0.2 percent lower), the Intel Core i7-12850HX with 41779 (0.3 percent higher), and the Intel Core i7-14700T with 41914 (0.6 percent higher). The Core 7 251TE sits within 1 percent of all four rivals, indicating that it performs at parity with these processors despite different core counts and power envelopes.

Because the U300L has no recorded benchmarks, the largest win in this comparison is the Core 7 251TE in every measured category. The U300L's lack of data means that any quantitative comparison would be speculative. The only concrete differentiators are the specifications: core count, cache size, memory bandwidth, PCIe generation, ECC support, and TDP.
