Intel Core 7 251E vs Intel Core i5-14501E Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the Intel Core 7 251E versus the Intel Core i5-14501E. Both processors show an average benchmark score of 0, and neither has any associated benchmark results in the database. The wins counters for both parts are 0, indicating no measured performance advantage for either CPU in direct comparison tests.

Without benchmark data, the only quantitative performance indicators available are the core counts, thread counts, clock speeds, and cache configurations recorded in the database. The Core 7 251E lists 24 cores and 32 threads, while the Core i5-14501E lists 6 cores and 12 threads. That is a 4x difference in core count and a 2.67x difference in thread count. The base clock of the Core i5-14501E is 3.30 GHz compared to 2.10 GHz for the Core 7 251E, a 1.20 GHz advantage. The boost clock of the Core 7 251E is 5.60 GHz versus 5.20 GHz for the Core i5-14501E, a 0.40 GHz advantage.

Direct benchmark comparison is therefore not possible from the available data. The database shows both CPUs at the 50th percentile among all CPUs, which is a neutral positioning. The absence of measured scores means the relative performance must be inferred from architectural specifications rather than observed results.

Architecture Differences

The Intel Core 7 251E uses the Bartlett Lake codename, while the Intel Core i5-14501E uses the Raptor Lake-R codename and belongs to the Core 14th Gen series. The Core 7 251E is listed under the Core 7 (Bartlett Lake) generation, whereas the Core i5-14501E is listed under the Core i5 (Raptor Lake Refresh) generation. Both are fabricated on a 10 nm process node at Intel foundry.

The die size differs between the two. The Core 7 251E measures 257 mm², while the Core i5-14501E measures 215 mm². That is a 42 mm² difference in silicon area. The larger die of the Core 7 251E aligns with its higher core count.

Cache organization shows notable differences. Both processors list 80 KB of L1 cache per core. The L2 cache per core is 2 MB for the Core 7 251E versus 1.25 MB for the Core i5-14501E. The L3 cache is 36 MB shared for the Core 7 251E versus 24 MB shared for the Core i5-14501E. The Core 7 251E has 0.75 MB more L2 per core and 12 MB more L3 overall.

Memory bandwidth is recorded only for the Core 7 251E at 89.6 GB/s. No memory bandwidth figure is listed for the Core i5-14501E in the database. Both support dual-channel DDR4 and DDR5 memory, and both support ECC memory.

Both processors use Intel Socket 1700, integrate UHD Graphics 770, and support PCIe Gen 5 with 16 lanes (CPU only). Neither processor has an unlocked multiplier. The Core 7 251E has a part number of SRQDUQ657, while the Core i5-14501E has a part number of Q49HSRNJM.

The market segment for both is Desktop, and both have Active production status. The Core 7 251E has a launch MSRP of $384. No launch MSRP is recorded for the Core i5-14501E.

The Verdict

The data indicates two very different processor designs aimed at different workload profiles. The Intel Core 7 251E provides 24 cores and 32 threads, which is a 4x core advantage and a 2.67x thread advantage over the Core i5-14501E. For multi-threaded workloads that scale with core count, the Core 7 251E has the structural advantage based on the recorded specifications.

The Core i5-14501E counters with a higher base clock of 3.30 GHz versus 2.10 GHz. For lightly threaded tasks where single-core frequency dominates, the Core i5-14501E holds the base clock advantage. However, the Core 7 251E has the higher boost clock at 5.60 GHz versus 5.20 GHz, which means the Core 7 251E can reach higher peak frequencies under boost conditions.

The cache hierarchy favors the Core 7 251E in both L2 and L3 capacity. The 36 MB L3 cache versus 24 MB provides 50% more shared cache. The larger per-core L2 of 2 MB versus 1.25 MB also gives the Core 7 251E more local cache per thread.

Both processors share the same socket, memory types, PCIe generation, and integrated graphics. They also both support ECC memory, which positions them for reliability-sensitive applications. The Core 7 251E is the only one with a recorded memory bandwidth figure of 89.6 GB/s.

The release timing shows the Core 7 251E launched approximately six months after the Core i5-14501E. Both are active products in the desktop segment. The Core 7 251E is the newer design with the Bartlett Lake codename, while the Core i5-14501E uses the Raptor Lake-R architecture.

For users prioritizing parallel throughput, the Core 7 251E offers the clear specification advantage with 4x the cores and 2.67x the threads. For users prioritizing base clock frequency in single-threaded scenarios, the Core i5-14501E provides a 1.20 GHz higher base clock. The recorded data does not include benchmark scores, so measured performance cannot be cited for either direction.
