Intel Core 7 251E vs Intel Core 7 253PE Comparison

Intel Core 7 251E and Intel Core 7 253PE are both desktop processors built on the Bartlett Lake architecture, sharing the same Intel Socket 1700, a 65-watt TDP, and a launch MSRP of $384. Despite these similarities, the recorded data shows two very different performance profiles, driven primarily by core counts and cache allocations. The 251E offers 24 cores and 32 threads, while the 253PE offers 10 cores and 20 threads, a difference that dominates the benchmark results.

Head-to-Head Benchmarks

The benchmark database contains a complete set of measurements for the Intel Core 7 253PE, while the Intel Core 7 251E has no recorded benchmark scores in the database. This asymmetry means the direct comparison relies entirely on the 253PE’s scores and its position relative to other processors. The 253PE achieves an average benchmark score of 40557, placing it in the 87th percentile of all CPUs. Its nearest rivals include the Intel Core 5 223PE with an average score of 40585, a delta of -0.1%, the Intel Core Ultra X7 368H with 40518, a delta of 0.1%, the Intel Xeon 6357P with 40630, a delta of -0.2%, and the AMD Ryzen 9 7940H with 40431, a delta of 0.3%. These deltas indicate the 253PE sits in a tight cluster where performance differences among rivals are negligible, within a range of roughly half a percent.

Looking at the 253PE’s individual benchmark results, the Cinebench R23 multicore score is 24880, while the singlecore score is 3512. The multicore result is approximately seven times the singlecore result, which aligns with the processor’s 10 cores and 20 threads, though the scaling is not perfect. In Cinebench R20, the multicore score is 10449 and the singlecore score is 1475, showing a similar ratio. The Cinebench R15 results continue the pattern with a multicore score of 2507 and a singlecore score of 354.

The Passmark suite reveals specific strengths. The multithread score is 29271, while the single thread score is 3955. The data compression score is 339133, which is a substantial result compared to the integer math score of 114158 and floating point math score of 80870. The extended instructions score is 21806, and data encryption scores 18385. The find prime numbers score is 138, which appears low relative to other integer workloads, and the physics score is 1845, while random string sorting scores 32777.

Since the 251E has no benchmark entries, the database cannot confirm its wins in any specific test. The wins counter shows 0 for the 251E and 0 for the 253PE in head-to-head comparisons, reflecting the absence of paired benchmark data. The available evidence therefore only characterizes the 253PE’s absolute performance and its competitive position against the four listed rivals, not a direct measurement against the 251E.

Architecture Differences

Both processors use the same 10 nm process node from Intel and share the Bartlett Lake codename. The 251E has 24 cores and 32 threads, while the 253PE has 10 cores and 20 threads. This core count difference is the most significant architectural gap, as the 251E provides more than double the cores and a 60% increase in thread count compared to the 253PE.

The cache hierarchy differs as well. Both processors have 80 KB of L1 cache per core and 2 MB of L2 cache per core. The shared L3 cache is 36 MB on the 251E, while the 253PE has 33 MB. The die size is recorded as 257 mm² for the 251E, while the 253PE has no die size listed in the database. The 251E also includes UHD Graphics 770 as its integrated graphics, whereas the 253PE uses UHD Graphics 730.

Memory support is identical across both parts: DDR4 and DDR5 memory with dual-channel bus and 89.6 GB/s bandwidth. Both support ECC memory and use PCIe Gen 5 with 16 lanes from the CPU. Both processors have locked multipliers, are active in production, and target the desktop market segment. The release dates differ, with the 251E released on 2025-01-12 and the 253PE released on 2026-03-08. The part numbers differ as well, with the 251E listed as SRQDUQ657 and the 253PE as SA4QE.

The Verdict

The data indicates that the Intel Core 7 253PE is the only one of the two with recorded performance measurements. Its 87th percentile ranking and average score of 40557 place it among capable desktop processors, closely matched with the AMD Ryzen 9 7940H and several Intel parts. The 251E lacks any benchmark data, so the database cannot substantiate its performance level or compare it directly.

For users selecting between these two processors strictly from the recorded data, the 253PE is the only option with demonstrated scores. Its 10 cores and 20 threads deliver a Cinebench R23 multicore score of 24880, which is a strong result for a 65-watt desktop part. The 251E’s 24 cores and 32 threads suggest a higher theoretical multi-threaded capacity, but without benchmark scores, that capacity remains unverified in this database. The 251E also carries a larger 36 MB L3 cache and a larger die size of 257 mm², which may indicate a more complex design, but the performance implications are not quantified.

The 253PE’s nearest rival comparisons show it trading places with processors within a 0.3% delta, meaning its performance is effectively tied with the AMD Ryzen 9 7940H and Intel Core Ultra X7 368H. The data does not reveal a decisive advantage over these rivals. The choice between the 251E and 253PE hinges on the unmeasured potential of the 251E versus the confirmed results of the 253PE.

Where Each One Wins

The Intel Core 7 253PE wins in the only category with available data: verified performance. Its benchmark suite shows strong multicore throughput with a Cinebench R23 multicore score of 24880, a Cinebench R20 multicore score of 10449, and a Cinebench R15 multicore score of 2507. The Passmark multithread score of 29271 reinforces this strength. The 253PE also demonstrates solid single-thread performance with a Cinebench R23 singlecore score of 3512 and a Passmark single thread score of 3955. Its data compression score of 339133 and integer math score of 114158 indicate heavy lifting in data processing tasks. The 253PE’s percentile ranking of 87 and its tight delta against rivals like the Intel Core 5 223PE and Intel Xeon 6357P confirm it operates in a competitive performance band.

The Intel Core 7 251E wins on paper in architectural capacity. Its 24 cores and 32 threads exceed the 253PE’s 10 cores and 20 threads, and its 36 MB L3 cache is 3 MB larger. The 251E also has a larger die at 257 mm², suggesting a more extensive silicon implementation. The 251E includes UHD Graphics 770, a higher-tier integrated graphics option than the 253PE’s UHD Graphics 730. For workloads that scale with core count, the 251E’s configuration appears positioned for higher multi-threaded output, but the absence of benchmark scores means the database cannot confirm this advantage in practice.
