Intel Core i7-14701E vs Qualcomm Snapdragon X2E-78-100 Comparison

Head-to-Head Benchmarks

The Intel Core i7-14701E and Qualcomm Snapdragon X2E-78-100 cannot be compared directly through head-to-head benchmark scores, as the database contains no overlapping benchmark results for these two processors. The Intel part has a comprehensive suite of 17 recorded benchmark scores, while the Qualcomm part has no recorded benchmark entries at all. This absence of data means that any quantitative comparison must rely on the Intel processor's absolute scores and its position among its nearest rivals, rather than a direct matchup.

The Intel Core i7-14701E delivers a Cinebench R23 multicore score of 22195 and a single-core score of 3133. In the older Cinebench R20 test, it records 9321 multicore and 1315 single-core points, while the R15 iteration shows 2237 multicore and 315 single-core points. These results indicate a processor that scales strongly across generations of the Cinebench suite, with multicore performance improving by roughly 2.4 times from R15 to R23.

PassMark results further characterize the Intel part. The multithread score sits at 26112, with single-thread performance at 4305. Integer math reaches 81325, floating point math hits 61873, and extended instructions score 18528. Data compression records 282939, data encryption 14862, and random string sorting 29158. Physics processing scores 2399, while find prime numbers scores 176. The average benchmark score for the Intel processor is 33206, placing it in the 83rd percentile among all CPUs in the database.

The nearest rivals for the Intel part provide context for its standing. The AMD Ryzen 9 PRO 6950H posts an average score of 33201, a delta of 0 percent. The AMD Ryzen 5 8645HS scores 33244, which is 0.1 percent higher. The AMD Ryzen 7 7745HX records 33091, a 0.3 percent deficit, and the Intel Core i7-13650HX scores 33089, also 0.3 percent behind. These margins are minimal, showing that the Core i7-14701E sits in a tightly contested performance band where differences of less than half a percent separate the contenders.

For the Qualcomm Snapdragon X2E-78-100, the database records an average benchmark score of 0, a 50th percentile ranking, and no nearest rivals. Without benchmark data, no wins or losses can be assigned to either processor in a head-to-head sense. The Intel part dominates the available data by default, but this should be read as a data availability gap rather than a performance verdict.

Architecture Differences

The two processors diverge fundamentally in their design targets. The Intel Core i7-14701E is a desktop part built on the Raptor Lake architecture, specifically the Raptor Lake-R codename, and belongs to the Core 14th Gen series. It uses 8 cores and 16 threads, reflecting Hyper-Threading support. The base clock is 2.60 GHz with a boost clock of 5.40 GHz. The process node is 10 nm, fabricated by Intel, with a die size of 257 mm². It uses the Intel Socket 1700.

The Qualcomm Snapdragon X2E-78-100 is a mobile processor with the codename Glymur, part of the Snapdragon X2 (Elite) generation. It uses 12 cores and 12 threads, indicating no simultaneous multi-threading. The base clock is 4.00 GHz with no boost clock recorded. It is built on a 3 nm process node at TSMC, with a die size of 220 mm². The socket is Qualcomm BGA 2343.

Cache hierarchies differ markedly. The Intel part provides 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The Qualcomm part provides 288 KB of L1 cache per core and 16 MB of shared L2 cache, with no L3 cache recorded. This arrangement gives the Qualcomm processor a larger per-core L1 allocation but a smaller shared pool, while the Intel processor relies on a substantial L3 cache for cross-core data sharing.

Memory support also separates the two. The Intel processor supports both DDR4 and DDR5 memory on a dual-channel bus, with ECC memory support enabled. The Qualcomm processor supports LPDDR5X memory on a dual-channel bus with a recorded memory bandwidth of 152.4 GB/s, but no ECC support. The Intel part does not have a recorded memory bandwidth figure in the database.

PCIe connectivity differs as well. The Intel processor provides Gen 5 with 16 lanes (CPU only), while the Qualcomm part provides Gen 5 with 12 lanes (CPU only). Integrated graphics also differ: the Intel part uses UHD Graphics 770, while the Qualcomm part uses Adreno X2-85.

Process node and foundry represent a major architectural split. The 3 nm TSMC fabrication for the Qualcomm part versus the 10 nm Intel fabrication for the Intel part suggests different transistor density and power characteristics, though the database does not record transistor counts for either. The Intel part carries a TDP of 65 watts, while the Qualcomm part has no TDP recorded. Neither processor has an unlocked multiplier. The Intel part is listed as Active in production status with a release date of June 30, 2024; the Qualcomm part is also Active, with a release date of April 5, 2026.

Where Each One Wins

The Intel Core i7-14701E wins in every category where benchmark data exists, simply because the Qualcomm Snapdragon X2E-78-100 has no recorded scores. The Intel part demonstrates strength in multithreaded workloads through its Cinebench R23 multicore score of 22195 and PassMark multithread score of 26112. The 16 threads, despite fewer physical cores than the Qualcomm part, allow it to handle parallel tasks effectively. The 33 MB shared L3 cache and per-core L2 cache of 2 MB support workloads that reuse data across cores.

Single-thread performance for the Intel part is strong as well, with a Cinebench R23 single-core score of 3133 and a PassMark single-thread score of 4305. The 5.40 GHz boost clock drives this result, making the processor well suited for latency-sensitive tasks that depend on a single core's speed. Integer and floating point math scores of 81325 and 61873 respectively indicate broad compute capability across both integer-heavy and floating-point-heavy code paths.

The Qualcomm Snapdragon X2E-78-100 wins only in architectural features that are recorded without benchmark validation. Its 12 cores and 12 threads provide a higher physical core count than the Intel part's 8 cores and 16 threads. The 4.00 GHz base clock is higher than the Intel part's 2.60 GHz base clock, which may benefit sustained workloads that do not rely on boost behavior. The 152.4 GB/s memory bandwidth, tied to LPDDR5X support, exceeds the Intel part's unspecified bandwidth, potentially aiding memory-bound operations.

The 3 nm process node from TSMC gives the Qualcomm part a fabrication advantage in density and efficiency, though the database does not quantify power draw or efficiency. The larger L1 cache of 288 KB per core could reduce latency for frequently accessed data. The 220 mm² die size is smaller than the Intel part's 257 mm², which may influence manufacturing economics, though pricing data is not recorded.

For desktop users, the Intel part offers ECC memory support, a feature absent from the Qualcomm part. For mobile users, the Qualcomm part integrates the Adreno X2-85 GPU and supports LPDDR5X memory, catering to portable designs. The Intel part integrates UHD Graphics 770, which serves desktop display needs without a discrete GPU.
