Intel Core 7 251TE vs Qualcomm Snapdragon X2E-78-100 Comparison

Head-to-Head Benchmarks

The database contains no overlapping benchmark records for the Intel Core 7 251TE and the Qualcomm Snapdragon X2E-78-100. The Intel part has 17 recorded benchmark scores across Cinebench R15, R20, R23, and Passmark tests. The Snapdragon X2E-78-100 has zero recorded benchmark scores in the database.

Because head-to-head results are unavailable, direct score comparisons cannot be constructed. The Intel Core 7 251TE posts an average benchmark score of 41650 across its suite, placing it at the 88th percentile of all CPUs tracked in the database. The Snapdragon X2E-78-100 holds a 50th percentile placement with an average benchmark score of 0, reflecting the absence of measured data rather than a performance verdict.

The Intel part shows notable strength in multithreaded workloads from its recorded tests. Cinebench R23 multicore reaches 25518 points, while the Passmark multithread score is 30022. Single-thread performance is comparatively strong as well: Cinebench R23 single-core scores 3602, and Passmark single-thread scores 3568. Passmark integer math reaches 125739, floating-point math hits 85607, and data compression scores 334399. Data encryption records 22176, extended instructions score 16974, and random string sorting reaches 39643. Physics simulation scores 1938, and prime number finding scores 140.

The Snapdragon part cannot be evaluated on any of these metrics, since no benchmark entries exist for it in the database. Its percentile rank of 50 is a placeholder derived from the absence of scores, not a measured position.

Where Each One Wins

The Intel Core 7 251TE wins on core count, thread count, and cache hierarchy depth. Its 24 cores and 32 threads provide a substantial advantage in heavily parallel workloads, and the 36 MB of shared L3 cache offers a large pool for data reuse across cores. The 5.40 GHz boost clock gives it a strong single-thread ceiling, and its 45 W TDP is explicitly recorded. The recorded benchmark scores, including a Cinebench R23 multicore score of 25518 and a Passmark multithread score of 30022, confirm its capability in multithreaded tasks. The 88th percentile ranking among all CPUs in the database reflects that measured strength.

The Qualcomm Snapdragon X2E-78-100 wins on process technology and memory bandwidth. Its 3 nm process at TSMC represents a more advanced manufacturing node than Intel's 10 nm process, which typically enables better power efficiency per operation. The 152.4 GB/s memory bandwidth is roughly 70% higher than the Intel part's 89.6 GB/s, and the LPDDR5X support is tailored for mobile platforms where power and bandwidth balance matter. Its 4.00 GHz base clock is considerably higher than the Intel part's 1.40 GHz base clock, indicating a different operating profile. The 12-core, 12-thread configuration with 288 KB of L1 per core and 16 MB of shared L2 suggests a design focused on responsiveness and efficiency rather than raw thread scaling. The mobile market segment and 2026 release date position it for a different usage context than the desktop-oriented Intel part.

The data shows no direct head-to-head wins for either processor, since the benchmark suites do not overlap. The Intel part has comprehensive measured results; the Snapdragon part has none. Consequently, any performance-based win assignment rests solely on the Intel side, while the Snapdragon side wins on specification advantages in process node, memory bandwidth, and base clock. The Intel part holds the advantage in core count, thread count, cache size, PCIe lane count, ECC support, and recorded benchmark performance. The Snapdragon part holds the advantage in process node, memory bandwidth, base clock, and L1 cache per core.
