Intel Processor U302L vs Qualcomm Snapdragon X1E-78-100 Comparison

The Verdict

The data positions the Intel Processor U302L as a low-power, entry-level mobile part with 5 cores and 6 threads, while the Qualcomm Snapdragon X1E-78-100 is a higher-end 12-core processor with a 35 W TDP. Benchmark results indicate that the Snapdragon X1E-78-100 is intended for workloads that scale across many cores, whereas the Intel U302L targets efficiency and basic productivity. The Qualcomm part uses a 4 nm TSMC process, a newer node than Intel's 10 nm process, which suggests better transistor density and power efficiency per clock. The Intel U302L has a launch MSRP of $285; the Snapdragon X1E-78-100 has no recorded launch MSRP.

The recorded data shows that the Snapdragon X1E-78-100 delivers a 3.40 GHz base clock, while the Intel U302L operates at a 1.20 GHz base clock and a 2.40 GHz boost clock. The Qualcomm part has no listed boost clock, which limits direct comparison on peak frequency. The Intel part has a 15 W TDP, which is less than half of the Qualcomm's 35 W TDP, making it the lower-power option. The Snapdragon X1E-78-100 supports LPDDR5X memory with a dual-channel bus and a recorded memory bandwidth of 135.2 GB/s; the Intel U302L supports DDR4 and DDR5 with no memory bandwidth figure in the database.

For users prioritizing battery life and moderate workloads, the Intel U302L is the appropriate choice based on its lower TDP. For users needing many cores and high memory bandwidth, the Snapdragon X1E-78-100 is the stronger option. Both parts are active in production and target the mobile segment.

Architecture Differences

The Intel Processor U302L uses the Raptor Lake architecture with the codename Raptor Lake-PS and belongs to the Intel Processor (Raptor Lake) generation. It is built on a 10 nm process node at Intel's foundry. The Snapdragon X1E-78-100 uses the Oryon codename, belongs to the Snapdragon X (Elite) generation, and is fabricated on a 4 nm process at TSMC. The process node difference is significant: 10 nm versus 4 nm indicates a generational gap in manufacturing technology.

The Intel U302L has 5 cores and 6 threads, which implies a hybrid or asymmetric core arrangement, though the database does not specify core types. The Snapdragon X1E-78-100 has 12 cores and 12 threads, indicating no hyperthreading or equivalent technology. The Intel part has a 1.20 GHz base clock and a 2.40 GHz boost clock; the Qualcomm part has a 3.40 GHz base clock and no boost clock listed.

Cache configurations differ substantially. The Intel U302L has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 10 MB of shared L3 cache. The Snapdragon X1E-78-100 has 288 KB of L1 cache per core, 12 MB of L2 cache per module, and 6 MB of shared L3 cache. The Qualcomm part's L2 cache structure is per module rather than per core, which reflects a different cache hierarchy design. The Intel part has a larger shared L3 cache (10 MB vs 6 MB), but the Qualcomm part has larger per-core L1 and per-module L2 caches.

Memory support differs: the Intel U302L supports DDR4 and DDR5, while the Snapdragon X1E-78-100 supports LPDDR5X only. Both use a dual-channel memory bus. The Qualcomm part has a recorded memory bandwidth of 135.2 GB/s; no bandwidth figure exists for the Intel part. The Intel U302L has 8 PCIe Gen 4 lanes (CPU only), while the Snapdragon X1E-78-100 has 12 PCIe Gen 4 lanes (CPU only). Neither part supports ECC memory.

Integrated graphics also differ. The Intel U302L uses UHD Graphics 80EU, while the Snapdragon X1E-78-100 uses Adreno X1-85. The database does not provide performance metrics for either iGPU. Sockets differ as well: the Intel part uses Intel Socket 1700, and the Qualcomm part uses Qualcomm BGA 2073. The Intel part has a part number of SRPKGQ5CX, while the Qualcomm part has X1E78100. The Intel U302L was released on 2024-04-07, and the Snapdragon X1E-78-100 was released on 2024-04-23.

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either processor, and the head-to-head benchmark array is empty. Both processors have an average benchmark score of 0 and a percentile rank of 50 against all CPUs. The winsA and winsB fields are both 0, meaning no competitive benchmark wins are recorded for either part.

The lack of benchmark data means the analysis must rely on architectural and specification differences. The Snapdragon X1E-78-100 has a base clock of 3.40 GHz, which is 2.20 GHz higher than the Intel U302L's 1.20 GHz base clock. The Intel U302L has a boost clock of 2.40 GHz, which the database lists, while the Qualcomm part has no boost clock entry. The Intel part's boost clock is 1.00 GHz higher than its own base clock, but it still trails the Qualcomm part's base clock by 1.00 GHz.

Core count favors the Qualcomm part: 12 cores versus 5 cores, a difference of 7 cores. Thread count also favors Qualcomm: 12 threads versus 6 threads, a difference of 6 threads. For multi-threaded workloads, the Qualcomm part has a clear structural advantage. The Intel part's 6 threads on 5 cores suggests some form of simultaneous multithreading, while the Qualcomm part's 12 threads on 12 cores indicates a flat 1:1 ratio.

Memory bandwidth strongly favors the Qualcomm part. The Snapdragon X1E-78-100 records 135.2 GB/s, while the Intel U302L has no bandwidth figure in the database. The Qualcomm part also has more PCIe lanes: 12 versus 8. The Intel part supports DDR4 and DDR5, which could be an advantage for platforms needing legacy memory compatibility, but the Qualcomm part's LPDDR5X support aligns with low-power mobile designs.

The TDP difference is notable: 15 W for Intel versus 35 W for Qualcomm. The Intel part consumes less than half the power of the Qualcomm part, which suggests lower sustained performance but better thermal characteristics for thin-and-light designs. The Qualcomm part's higher TDP likely enables sustained multi-core performance, but the database does not provide measured power or thermal data.
