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

Where Each One Wins

The benchmark data for these two processors is one-sided: every recorded performance result belongs to the Intel Core 7 253PTE. The Intel Core 7 251E has no benchmark entries in the database, meaning its win count sits at zero, while the 253PTE accounts for all measured scores across Cinebench and Passmark workloads. This is not a case of close margins; the 253PTE establishes a clear performance lead in every available test, from single-threaded operations to heavily threaded multi-core workloads.

The 253PTE's dominance is most pronounced in multi-threaded scenarios. In Cinebench R23 multi-core, it scores 21,276 points, a figure that places it in the 84th percentile of all CPUs tracked by the database. Its nearest rivals include the Intel Core i7-13800H (average score 34,988, delta -0.1%) and the Intel Core i9-12900HX (average score 35,003, delta -0.1%), showing that the 253PTE sits within a tight performance cluster at the top of the current field. The single-core results follow a similar pattern: Cinebench R23 single-core returns 3,003 points, and Passmark single-thread returns 3,794, both indicating strong per-thread efficiency.

For the 251E, the absence of recorded benchmarks means no performance claims can be made from the database. The data cannot confirm whether it wins or loses in any specific test. However, the specification differences between the two parts (detailed later) suggest the 251E is configured for a different role, one that does not prioritize raw throughput in the same way as the 253PTE.

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark comparisons between the two processors. All measured scores come from the 253PTE, and the 251E has no entries in any benchmark category. This makes a side-by-side numerical comparison impossible from the recorded data alone. What can be stated is the absolute performance level of the 253PTE and how it stands against its nearest rivals.

Starting with Cinebench R15, the 253PTE delivers 2,144 points in multi-core and 302 points in single-core. Moving to Cinebench R20, the multi-core score rises to 8,935 and single-core to 1,261. In Cinebench R23, the multi-core result reaches 21,276 and single-core reaches 3,003. These three Cinebench generations show a consistent scaling pattern: the multi-core scores improve substantially with each newer version, while single-core gains are more modest but still positive.

The Passmark suite adds further detail. The 253PTE scores 275,828 in data compression, 15,500 in data encryption, 17,099 in extended instructions, and 82 in find prime numbers. Floating-point math returns 67,209, integer math returns 119,552, and multithread returns 25,031. Physics scores 1,318, random string sorting scores 28,227, and single-thread scores 3,794 (reported twice under slightly different test names).

Against its nearest rivals, the 253PTE's average benchmark score is 34,962. The Intel Core i7-13800H averages 34,988 (a delta of -0.1%, meaning the rival is effectively tied), and the Intel Core i9-12900HX averages 35,003 (also -0.1%). On the other side, the Intel Xeon 6349P averages 34,890 (delta +0.2%, meaning the 253PTE is ahead by that margin), and the AMD Ryzen 5 150 averages 34,881 (delta +0.2%). These deltas are all within a fraction of a percent, so the 253PTE sits in a crowded performance band rather than standing alone at the top.

Specification Differences

The two processors share several fundamentals: both use Intel Socket 1700, both are built on Intel's 10 nm process, both come from the Bartlett Lake codename family, and both are listed as Active production parts. They also share the same PCIe configuration (Gen 5, 16 lanes CPU-only), the same dual-channel memory bus, the same 89.6 GB/s memory bandwidth, and identical ECC memory support.

The differences begin with core and thread counts. The 251E has 24 cores and 32 threads; the 253PTE has 10 cores and 20 threads. Base clocks differ as well: the 251E runs at 2.10 GHz, the 253PTE at 1.80 GHz. Boost clocks are closer, with the 251E reaching 5.60 GHz and the 253PTE reaching 5.40 GHz. TDP splits them further: 65 W for the 251E versus 45 W for the 253PTE.

Cache configurations also diverge. Both have 80 KB of L1 per core and 2 MB of L2 per core, but the shared L3 cache is 36 MB on the 251E and 33 MB on the 253PTE. The integrated graphics differ: UHD Graphics 770 on the 251E, UHD Graphics 730 on the 253PTE. Die size is listed only for the 251E at 257 mm²; no die size is recorded for the 253PTE. Release dates differ by over a year: the 251E launched on 2025-01-12, the 253PTE on 2026-03-08. Both carry the same launch MSRP of $384, and neither has an unlocked multiplier.

Architecture Differences

Both processors are based on the Bartlett Lake architecture, Intel's 10 nm process, and the Socket 1700 platform. The architectural relationship is therefore close, but the implementation details create distinct profiles.

The 251E is clearly built for higher core counts. With 24 cores and 32 threads, it presents a 2.4x core advantage over the 253PTE's 10 cores and 20 threads. The thread count advantage is 1.6x. This suggests the 251E targets workloads that scale with parallel execution, such as multi-threaded rendering, compilation, or scientific computation. Its higher base clock (2.10 GHz versus 1.80 GHz) and higher boost clock (5.60 GHz versus 5.40 GHz) reinforce a performance-first orientation, though at a higher TDP of 65 W.

The 253PTE, by contrast, uses fewer cores but still maintains high boost capability. Its 5.40 GHz boost clock is only 0.20 GHz below the 251E, and its 45 W TDP indicates a more power-conscious design. The smaller L3 cache (33 MB versus 36 MB) and the lower-end UHD Graphics 730 (versus UHD Graphics 770) further position it as a mid-range part within the same architecture.

The shared L1 and L2 cache sizes per core (80 KB and 2 MB respectively) indicate that both chips use the same core design; the difference lies in how many cores are instantiated and how the shared L3 is sized. The 251E's larger die (257 mm²) aligns with its higher core count, while the 253PTE's die size is unlisted, so no direct comparison can be made from the data.

Both support the same memory types (DDR4 and DDR5), the same dual-channel bus, and the same memory bandwidth. Both also support ECC memory, which is notable for workstation or server-adjacent usage. The PCIe configuration is identical at Gen 5 with 16 CPU lanes, so expansion capability does not differentiate them.

The Verdict

The recorded data points in one direction: the Intel Core 7 253PTE is the only one of the two with any benchmark results, and those results are strong. Its Cinebench R23 multi-core score of 21,276 and single-core score of 3,003, combined with a Passmark multithread score of 25,031 and a single-thread score of 3,794, place it in the 84th percentile of all CPUs. Its average benchmark score of 34,962 sits within 0.2% of its nearest rivals, meaning it performs on par with the Intel Core i7-13800H, Intel Core i9-12900HX, Intel Xeon 6349P, and AMD Ryzen 5 150.

The Intel Core 7 251E has no benchmark entries, so the database cannot substantiate any performance claim for it. What the specifications do show is a different design philosophy: 24 cores versus 10, 32 threads versus 20, a higher base clock (2.10 GHz versus 1.80 GHz), a slightly higher boost clock (5.60 GHz versus 5.40 GHz), a larger L3 cache (36 MB versus 33 MB), and a higher TDP (65 W versus 45 W). These numbers suggest the 251E is configured for heavily parallel workloads where core count matters more than per-thread speed, and its larger die size of 257 mm² supports that interpretation.

For a user choosing strictly from the data, the 253PTE is the part with proven performance, particularly for tasks that benefit from strong multi-threading and single-thread responsiveness. The 251E, without any measured benchmarks, cannot be recommended on the basis of performance evidence; its appeal would have to rest on its core and thread advantages, which the database does not currently validate with scores. The 253PTE's lower TDP also makes it the more power-efficient choice on paper, and its identical launch MSRP of $384 means no price-based differentiation exists between the two.
