Intel Core 7 251E vs Intel Processor 300 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores for these two processors. The benchmark arrays for both the Intel Core 7 251E and the Intel Processor 300 are empty, meaning no comparative performance measurements have been logged. The winsA and winsB fields both show zero, confirming that neither processor has a measured victory in any direct comparison.

The Intel Core 7 251E holds a 50th percentile rank among all CPUs in the database, as does the Intel Processor 300. Both processors sit at exactly the same percentile, which indicates their aggregate standing across all recorded processors is identical despite their very different specifications. However, without benchmark scores, the percentile values cannot be translated into specific performance deltas between the two.

The average benchmark score for both is recorded as zero, which reflects the absence of any logged test results rather than an actual performance measurement. This means the database currently offers no numerical basis for declaring either processor faster in single-threaded, multi-threaded, gaming, or productivity workloads.

Architecture Differences

The Intel Core 7 251E uses the Bartlett Lake codename and belongs to the Core 7 (Bartlett Lake) generation. The Intel Processor 300 uses the Raptor Lake architecture with the Raptor Lake-S codename and belongs to the Intel Processor (Raptor Lake) generation. Both processors are built on a 10 nm process node at Intel's foundry.

The core count difference is substantial. The Core 7 251E has 24 cores and 32 threads, while the Processor 300 has 2 cores and 4 threads. This represents a 12x difference in core count and an 8x difference in thread count. The base clock of the Core 7 251E is 2.10 GHz with a boost clock of 5.60 GHz, whereas the Processor 300 has a base clock of 3.90 GHz and no recorded boost clock.

Cache configurations diverge significantly. The Core 7 251E has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Processor 300 also has 80 KB of L1 cache per core, but its L2 cache is 1.25 MB per core and its shared L3 cache is only 6 MB. The total L3 cache difference is 30 MB in favor of the Core 7 251E.

The die size differs as well. The Core 7 251E measures 257 mm², while the Processor 300 measures 163 mm². This 94 mm² difference reflects the larger physical footprint required by the 24-core design.

Thermal design power also separates the two. The Core 7 251E has a TDP of 65 watts, while the Processor 300 has a TDP of 46 watts. The Core 7 251E consumes 19 watts more under its rated thermal envelope.

Memory support shows both processors support DDR4 and DDR5 with dual-channel memory buses. The Core 7 251E has a recorded memory bandwidth of 89.6 GB/s, while the Processor 300 has no recorded memory bandwidth figure. ECC memory support differs: the Core 7 251E supports ECC, while the Processor 300 does not.

Both processors use Intel Socket 1700 and offer PCIe Gen 5 with 16 lanes (CPU only). The integrated graphics differ, with the Core 7 251E featuring UHD Graphics 770 and the Processor 300 featuring UHD Graphics 710. Neither processor has an unlocked multiplier.

The release dates differ by roughly one year. The Processor 300 was released on 2024-01-07, while the Core 7 251E was released on 2025-01-12. Both processors are currently marked as Active in production status.

The Verdict

The data indicates a clear division of roles between these two processors. The Intel Core 7 251E is designed for heavily threaded workloads, evidenced by its 24 cores, 32 threads, 36 MB of L3 cache, and 89.6 GB/s memory bandwidth. The Intel Processor 300 is a minimal dual-core part with 4 threads, 6 MB of L3 cache, and no recorded memory bandwidth, suited for basic computing tasks.

The Core 7 251E also supports ECC memory, which the Processor 300 does not. This positions the Core 7 251E for reliability-sensitive environments such as entry-level servers or workstations where memory errors are a concern. The Processor 300 lacks this capability, limiting its use in those scenarios.

The release timeline shows the Processor 300 arrived first in January 2024, followed by the Core 7 251E in January 2025. Both remain active in production. The launch MSRP for the Core 7 251E is $384, and for the Processor 300 it is $82.

The Core 7 251E uses the Bartlett Lake architecture, while the Processor 300 uses Raptor Lake. The Core 7 251E has a larger die at 257 mm² compared to 163 mm² for the Processor 300. The TDP difference is modest in absolute terms, with the Core 7 251E rated at 65 watts versus 46 watts for the Processor 300.

Neither processor has an unlocked multiplier. Both are locked parts on Intel Socket 1700 with PCIe Gen 5, 16 lanes (CPU only). The Core 7 251E features UHD Graphics 770, and the Processor 300 features UHD Graphics 710.

The absence of benchmark scores means the database does not currently quantify the performance gap. The specification differences, however, strongly suggest the Core 7 251E dominates in multi-threaded throughput, while the Processor 300 offers a much lower base clock advantage of 3.90 GHz versus 2.10 GHz for the Core 7 251E, which could favor lightly threaded tasks before boost behavior is considered.

The parts share these specifications: Intel Socket 1700, DDR4 and DDR5 memory support, dual-channel memory bus, PCIe Gen 5 with 16 lanes (CPU only), 80 KB L1 cache per core, Intel as manufacturer and foundry, locked multiplier, Desktop market segment, and Active production status.

Where Each One Wins

The Intel Core 7 251E wins on raw multi-threading capability. Its 24 cores and 32 threads provide 12 times the core count of the Processor 300. The 36 MB of shared L3 cache versus 6 MB gives it a substantial cache advantage for workloads that repeatedly access large data sets. The 89.6 GB/s memory bandwidth, which the Processor 300 does not record, further supports data-intensive operations. ECC memory support adds reliability for error-sensitive computing environments. The 5.60 GHz boost clock gives it high single-thread headroom when needed, and the UHD Graphics 770 is the more capable integrated graphics solution.

The Intel Processor 300 wins on base clock frequency. Its 3.90 GHz base clock is 1.80 GHz higher than the Core 7 251E's 2.10 GHz base clock. For workloads that run at a fixed frequency without boost engagement, the Processor 300 delivers higher per-core throughput. Its 46 watt TDP is 19 watts lower than the Core 7 251E, making it the more power-efficient part on paper. The smaller die size of 163 mm² versus 257 mm² indicates a simpler and potentially less expensive manufacturing footprint. Its earlier release date in January 2024 means it has been available in the market longer than the Core 7 251E, which arrived in January 2025.

The database records no benchmark wins for either processor. The winsA and winsB fields both show zero, and the head-to-head benchmark array is empty. Therefore, the analysis above is based entirely on the recorded specification differences, not on measured performance outcomes.
