Intel Core i5-14400F vs Qualcomm Snapdragon X2E-78-100 Comparison

Where Each One Wins

The Intel Core i5-14400F has a complete set of recorded benchmark data, while the Qualcomm Snapdragon X2E-78-100 has no recorded benchmark scores in the database. This makes the comparison one-sided in terms of measured performance. The Intel part sits at the 83rd percentile against all CPUs, with an average benchmark score of 32,279. The Snapdragon X2E-78-100 is at the 50th percentile, but its average benchmark score is recorded as 0, meaning no performance data has been collected for it yet.

With no benchmark entries for the Snapdragon, the Intel Core i5-14400F wins every measured category by default. The Intel chip delivers 10 cores and 16 threads, a configuration that supports simultaneous multithreading. The Snapdragon X2E-78-100 offers 12 cores and 12 threads, meaning it has no multithreading capability. In workloads that scale with thread count, the Intel part has a structural advantage: 16 threads versus 12. However, the Snapdragon has a higher base clock at 4.00 GHz versus 2.50 GHz, which could give it an edge in lightly threaded tasks if benchmark data existed to confirm that.

The Intel Core i5-14400F is a desktop part, while the Snapdragon X2E-78-100 targets mobile. This alone changes the expected use case. The Intel chip is designed for desktop workloads, where sustained power delivery and high thread counts matter. The Snapdragon is a mobile processor, which typically prioritizes efficiency and integration. Without benchmark data for the Snapdragon, the database records no wins for either side in head-to-head comparisons, but the Intel part has all 19 individual benchmark scores available for analysis.

Architecture Differences

The two processors come from different manufacturing and design philosophies. The Intel Core i5-14400F uses the Raptor Lake architecture, specifically Raptor Lake-R, and is built on a 10 nm process at Intel's foundry. The die size is 215 mm². The Qualcomm Snapdragon X2E-78-100 uses the Glymur codename, belongs to the Snapdragon X2 Elite generation, and is fabricated by TSMC on a 3 nm process with a die size of 220 mm². The Snapdragon's process node is significantly more advanced, which typically enables higher efficiency, but the database does not include power consumption figures for the Snapdragon to confirm this.

Cache layouts differ substantially. The Intel chip has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. The Snapdragon has 288 KB of L1 per core and 16 MB of shared L2, with no L3 cache listed. The Snapdragon's larger L1 per core could benefit single-threaded latency-sensitive workloads, while the Intel chip's L3 cache provides a shared pool for all cores.

Memory support diverges completely. The Intel Core i5-14400F supports both DDR4 and DDR5 memory over a dual-channel bus, and it supports ECC memory. The Snapdragon X2E-78-100 supports only LPDDR5X memory over a dual-channel bus, with no ECC support. The Snapdragon does list a memory bandwidth figure of 152.4 GB/s, which the Intel part does not have recorded. This suggests the Snapdragon is optimized for high-bandwidth, low-power memory typical of mobile platforms.

PCIe connectivity also differs. The Intel chip offers Gen 5 with 16 lanes (CPU only). The Snapdragon offers Gen 5 with 12 lanes (CPU only). Both use PCIe Gen 5, but the Intel part has more available lanes for expansion. The Snapdragon includes integrated graphics, specifically an Adreno X2-85, while the Intel Core i5-14400F has no integrated graphics at all, listed as N/A.

Socket and market segment reinforce the architectural split. The Intel part uses Intel Socket 1700 and is a desktop processor. The Snapdragon uses Qualcomm BGA 2343 and is a mobile processor. The Intel chip has a launch MSRP of $196, while the Snapdragon has no launch MSRP recorded. Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

The database records no head-to-head benchmark comparisons between the Intel Core i5-14400F and the Qualcomm Snapdragon X2E-78-100. The headToHeadBenchmarks field is empty. The winsA and winsB fields are both 0. This means there are no direct side-by-side measurements in the database.

However, the Intel Core i5-14400F has a full suite of individual benchmark scores. In Cinebench R23, the Intel part scores 21,645 in multi-core and 3,055 in single-core. In Cinebench R20, it scores 9,090 multi-core and 1,283 single-core. In Cinebench R15, it scores 2,181 multi-core and 307 single-core. In Geekbench, it scores 11,268 multi-core and 2,058 single-core.

PassMark results for the Intel chip include a multithread score of 25,470 and a single-thread score of 3,701. Specific workload tests show 31,5521 in data compression, 16,949 in data encryption, 19,937 in extended instructions, 86 in finding prime numbers, 61,319 in floating point math, 81,524 in integer math, 1,523 in physics, and 32,680 in random string sorting. These scores place the Intel part at the 83rd percentile against all CPUs.

Nearest rivals in the database for the Intel Core i5-14400F include the AMD Ryzen 7 PRO 8840U with an average score of 32,233 and a delta of 0.1%, the Intel Core i9-11900 with an average score of 32,226 and a delta of 0.2%, the AMD Ryzen 7 6800HS with an average score of 32,354 and a delta of -0.2%, and the Intel Core i7-12800H with an average score of 32,121 and a delta of 0.5%. These deltas are all within half a percent, meaning the Intel Core i5-14400F performs essentially on par with these four processors in average benchmark score.

The Snapdragon X2E-78-100 has no benchmark scores, no average benchmark score, and no nearest rivals recorded. The database shows its percentile as 50, but this is based on no measured data. Any performance comparison between the two processors in the database is therefore limited to architectural differences and the Intel part's recorded performance.
