Intel Core 7 251TE vs Intel Core 7 253PQE Comparison

Head-to-Head Benchmarks

The benchmark data presents an unambiguous picture: the Intel Core 7 253PQE wins every single recorded comparison against the Intel Core 7 251TE, taking all 17 head-to-head tests. The closest margins appear in integer and encryption workloads, while the widest gaps show up in extended instruction processing and physics simulations.

In Cinebench testing, the 253PQE leads by nearly identical margins across all versions. The R15 multicore test shows 3163 versus 2572, a delta of 18.7 percent. R20 multicore follows the same pattern: 13183 versus 10717, again 18.7 percent. R23 multicore delivers 31390 versus 25518, also an 18.7 percent gap. Single-core results mirror this trend, with the 253PQE posting 446, 1861, and 4431 in R15, R20, and R23 respectively, while the 251TE manages 362, 1512, and 3602. The deltas here are 18.8, 18.8, and 18.7 percent.

PassMark workloads show more variation. The largest single advantage for the 253PQE is in extended instructions, where it scores 32390 against 16974, a 47.6 percent lead. Physics testing also favors the 253PQE heavily: 2970 versus 1938, a 34.7 percent margin. Data compression shows a 31.4 percent gap, with scores of 487335 versus 334399. Multi-threaded performance in PassMark gives the 253PQE a 27.9 percent edge, 41656 versus 30022. Random string sorting follows at 26.9 percent, 54222 versus 39643.

The narrower margins are still decisive. Data encryption sees the 253PQE at 25515 against 22176, a 13.1 percent win. Integer math produces 137795 versus 125739, an 8.7 percent advantage, the closest result in the entire comparison. Floating-point math lands at 105279 versus 85607, an 18.7 percent gap. Prime number finding shows 206 versus 140, a 32 percent difference.

The 251TE records zero wins across all tests. Its average benchmark score sits at 41650, placing it in the 88th percentile of all CPUs. The 253PQE averages 55919, which puts it in the 91st percentile. That average score places the 253PQE within 0.2 percent of the Intel Core i9-14900HX, 0.6 percent of the AMD Ryzen AI Max 390, 0.7 percent of the AMD Ryzen AI 9 HX PRO 470, and 1.1 percent of the AMD Ryzen Threadripper PRO 3955WX. The 251TE, by comparison, sits within 0.1 percent of the Intel Core Ultra 7 265H, 0.2 percent of the Intel Core i7-14650HX, 0.3 percent of the Intel Core i7-12850HX, and 0.6 percent of the Intel Core i7-14700T.

Architecture Differences

Both processors share the Bartlett Lake codename, the 10 nm process node, and Intel as the foundry. Both are desktop parts with the same socket, memory support, PCIe configuration, and integrated graphics. The structural differences lie in core layout and cache distribution.

The 251TE packs 24 cores and 32 threads, indicating a hybrid arrangement where not every core contributes a thread. Its L2 cache is 1.25 MB per core, and its L3 totals 36 MB. The die size is listed at 215 mm². The 253PQE uses 10 cores and 20 threads, meaning every core provides two threads. Its L2 cache is larger per core at 2 MB, while its L3 is slightly smaller at 33 MB. No die size is recorded for the 253PQE.

Base clocks differ substantially. The 251TE runs at 1.40 GHz base, while the 253PQE starts at 3.50 GHz. Boost clocks are closer: 5.40 GHz for the 251TE and 5.70 GHz for the 253PQE. The thermal design power reflects this, with the 251TE rated at 45 watts and the 253PQE rated at 125 watts. This explains why the 253PQE sustains higher clocks under load despite having fewer cores.

The 251TE launched on 2025-01-12 with a launch MSRP of $384 and part number SRQAXQ5ZG. The 253PQE launched on 2026-03-08 with a launch MSRP of $409 and part number SA4QA. Both are marked as Active in production.

The 251TE's 24-core design with low base clock and 45 watt TDP suggests a power-conscious configuration with many efficiency-oriented cores. The 253PQE's 10-core, 20-thread layout with high base clock and 125 watt TDP points toward a smaller number of performance-focused cores running at higher sustained rates. The benchmark results confirm that the 253PQE's approach delivers substantially better throughput in every measured workload.

The Verdict

The data leaves no room for ambiguity. The Intel Core 7 253PQE outperforms the Intel Core 7 251TE in all 17 recorded benchmarks. The smallest margin is 8.7 percent in integer math, and the largest is 47.6 percent in extended instructions. The 253PQE also holds a higher percentile ranking, 91st versus 88th, and its average benchmark score of 55919 exceeds the 251TE's 41650 by roughly 34 percent.

The 251TE does have advantages in the specification sheet. It offers more cores, more threads, more L3 cache, lower power draw, a smaller die, and an earlier release date. It also carries a lower launch MSRP: $384 versus $409. However, none of those specification advantages translate into a single benchmark victory. The 253PQE wins every test despite having 14 fewer cores and 12 fewer threads.

For workloads that stress extended instruction sets, physics calculations, data compression, or multi-threaded throughput, the 253PQE is the clear choice. Its margins in those areas range from roughly 27 to 48 percent. For workloads that depend on integer math, the gap narrows to 8.7 percent, but the 253PQE still wins. There is no recorded workload where the 251TE takes the lead.

The 251TE remains a capable processor in absolute terms, sitting in the 88th percentile of all CPUs and trading blows with the Intel Core Ultra 7 265H and Core i7-14650HX within a fraction of a percent. But in a direct comparison with the 253PQE, its performance profile does not compete. The 253PQE performs like a much higher-tier part, matching the Intel Core i9-14900HX within 0.2 percent.

Where Each One Wins

The Intel Core 7 253PQE wins every benchmark category in the database. Its strongest relative performance comes in PassMark extended instructions, where it leads by 47.6 percent. It also excels in physics simulation with a 34.7 percent margin, data compression at 31.4 percent, and multi-threaded workloads at 27.9 percent. These results indicate a processor that handles mathematically intensive and parallel tasks with ease.

The 253PQE also dominates single-thread performance, posting an 18.7 percent lead in PassMark single-thread testing and 18.8 percent in Cinebench R15 single-core. Its boost clock of 5.70 GHz, combined with a 3.50 GHz base, gives it a substantial clock advantage that shows up across all single-threaded measurements.

The Intel Core 7 251TE has no benchmark wins to claim. Its best relative showing is in integer math, where it trails by only 8.7 percent, and data encryption, where the gap narrows to 13.1 percent. These are the workloads where the 251TE comes closest to matching the 253PQE, but it still loses both tests.

Where the 251TE does hold an edge is in the specification sheet alone. It offers more cores and threads, more L3 cache, lower power consumption at 45 watts versus 125 watts, and a smaller die at 215 mm². For a builder prioritizing core count, cache capacity, or power draw over measured performance, the 251TE has those attributes. But the recorded data shows that those attributes do not produce superior results in any of the 17 tested workloads. The 253PQE is the faster processor in every measurable category.
