Both processors hold a percentile rank of 50 against all CPUs in the database, indicating they sit at the median performance tier based on aggregate scores. The wins tally shows zero for each side, reflecting the absence of comparative test data rather than a performance tie. Without measured scores, the analysis shifts to architectural parameters and specification comparisons to infer relative strengths.

The Intel part reaches a boost clock of 4.70 GHz, while the Qualcomm part has no recorded boost clock value. In single-threaded workloads, higher peak frequency typically translates into faster response times, so the Intel processor likely holds an advantage in tasks that rely on one or two cores. The Qualcomm chip has a base clock of 4.00 GHz, which is 1.40 GHz higher than the Intel base clock of 2.60 GHz. This suggests that under sustained all-core loads, the Qualcomm processor may sustain higher minimum throughput per core before any boost behavior engages.

Multi-threaded performance hinges on thread count. The Intel part provides 12 cores and 16 threads, meaning four cores have hyper-threading. The Qualcomm part provides 12 cores and 12 threads, with no simultaneous multi-threading. For workloads that scale with thread count, the Intel processor can schedule 16 threads concurrently, while the Qualcomm processor schedules 12. That 33% thread advantage could translate into meaningful gains in heavily parallel tasks, assuming other factors such as memory bandwidth and cache hierarchy do not bottleneck.

The Qualcomm processor has a process node of 3 nm fabricated by TSMC, whereas the Intel processor uses 10 nm from Intel’s own foundry. The smaller node generally delivers better power efficiency per operation and higher transistor density. The die size for the Qualcomm chip is 220 mm², while no die size is recorded for the Intel chip. The die size, combined with the process node, indicates that the Qualcomm processor packs more transistors into a physically defined area, which may enable higher compute throughput per watt.

Architecture Differences

The Intel Core 5 120HL belongs to the Raptor Lake architecture, specifically the Raptor Lake-PS codename. This is a desktop segment processor using Intel Socket 1700. The Qualcomm Snapdragon X2E-78-100 uses the Glymur codename under the Snapdragon X2 (Elite) generation, targeting the mobile segment with Qualcomm BGA 2343 socket. The Intel architecture is listed as Raptor Lake, while the Qualcomm architecture field is null, indicating the database does not classify its microarchitecture beyond the codename.

Cache hierarchies differ substantially. The Intel processor has an L1 cache of 80 KB per core, an L2 cache of 2 MB per core, and an L3 cache of 18 MB shared. The Qualcomm processor has an L1 cache of 288 KB per core, an L2 cache of 16 MB shared, and no recorded L3 cache. The Qualcomm L1 cache is 3.6 times larger per core than the Intel L1 cache. Larger per-core L1 caches can reduce latency for frequently accessed data, improving single-thread performance. The Intel L2 cache is per core (2 MB per core across 12 cores yields 24 MB total), while the Qualcomm L2 cache is shared (16 MB total). Shared L2 caches allow dynamic allocation across cores, which can benefit bursty workloads but may cause contention under all-core loads.

The Intel processor supports DDR4 and DDR5 memory in a dual-channel configuration. The Qualcomm processor supports LPDDR5X memory in a dual-channel configuration with a recorded memory bandwidth of 152.4 GB/s. No memory bandwidth figure exists for the Intel part in the database. LPDDR5X is optimized for mobile power consumption, while DDR4 and DDR5 are typical desktop memory types. The Qualcomm memory bandwidth number provides a concrete throughput figure, which likely exceeds what a dual-channel DDR4 setup would deliver, though DDR5 dual-channel could approach similar values depending on speed grade.

PCIe support differs: the Intel part offers Gen 4 with 8 lanes (CPU only), while the Qualcomm part offers Gen 5 with 12 lanes (CPU only). The Qualcomm processor provides more PCIe lanes at a newer generation, doubling the per-lane bandwidth compared to Gen 4. This affects connectivity for GPUs, NVMe storage, and other peripherals. The Intel processor’s 8 lanes at Gen 4 may restrict high-bandwidth expansion in desktop builds.

Integrated graphics also diverge. The Intel processor includes Iris Xe Graphics with 80 execution units. The Qualcomm processor includes Adreno X2-85. Both are integrated, but the database provides no performance metrics for either GPU. The Intel graphics targets desktop use, while the Adreno series historically emphasizes power efficiency for mobile.

The manufacturing process shows a clear divide: Intel uses its own 10 nm node, while Qualcomm uses TSMC’s 3 nm node. The foundry difference (Intel vs TSMC) and process node difference (10 nm vs 3 nm) affect thermal density and power scaling. A 3 nm process typically allows lower voltage operation for the same frequency, which could reduce heat generation in sustained workloads.

Where Each One Wins

Based on clock and thread data, the Intel Core 5 120HL likely wins in scenarios that benefit from higher boost frequency and additional threads. The 4.70 GHz boost clock exceeds the Qualcomm base clock of 4.00 GHz, and since no Qualcomm boost clock exists, the Intel part’s peak frequency is the only recorded maximum across both. Single-threaded applications such as older games, spreadsheet calculations, or lightly threaded productivity tools would favor the Intel processor’s ability to reach 4.70 GHz on one core.

The Intel processor also wins in multi-threaded tasks that scale linearly with thread count. With 16 threads versus 12 threads, CPU-bound workloads like video encoding, 3D rendering, or compiling can use four additional threads. The 18 MB shared L3 cache also provides a sizable pool for shared data across cores, which can reduce memory traffic in certain parallel algorithms.

The Qualcomm Snapdragon X2E-78-100 wins in power-sensitive mobile environments. The 3 nm TSMC node and LPDDR5X memory support indicate a design optimized for battery life and thermal constraints. The 4.00 GHz base clock is high for a mobile chip, suggesting it can sustain near-peak performance without relying on boost behavior. The 16 MB shared L2 cache and 288 KB per-core L1 cache provide low-latency access to data, which benefits latency-sensitive workloads such as real-time signal processing or interactive mobile apps.

The Qualcomm processor also wins in memory bandwidth and PCIe connectivity. The recorded 152.4 GB/s memory bandwidth surpasses any figure for the Intel part (none recorded), so heavy data streaming workloads, such as AI inference or large dataset manipulation, would benefit. The Gen 5 PCIe with 12 lanes allows faster attachment of storage and accelerators, making the Qualcomm chip more suitable for platforms that require high-throughput I/O.

The Intel processor’s desktop segment classification means it can pair with DDR4 or DDR5 in a dual-channel setup, offering flexibility in memory choice. The Qualcomm chip’s mobile segment classification ties it to LPDDR5X, which is soldered and less upgradeable. For user-upgradeable desktop systems, the Intel part wins on memory flexibility.
