Intel Core 5 120 vs Qualcomm Snapdragon X2E-78-100 Comparison

Head-to-Head Benchmarks

The recorded data does not contain any direct head-to-head benchmark comparisons between the Intel Core 5 120 and the Qualcomm Snapdragon X2E-78-100. The head-to-head benchmark array is empty, and neither processor has a wins count assigned in the comparison table. This means there are no direct performance deltas to report from side-by-side testing.

What the database does provide is a complete benchmark profile for the Intel Core 5 120 and a set of aggregate characteristics for the Qualcomm part. The Intel chip has a full suite of Cinebench and PassMark results, while the Snapdragon X2E-78-100 has no recorded benchmark scores at all. Its average benchmark score is listed as 0, and it holds a 50th percentile position among all CPUs. The Intel Core 5 120, by contrast, sits at the 77th percentile with an average benchmark score of 25362.

Without head-to-head scores, the only numerical comparison available comes from the Intel chip's nearest rivals. The Core 5 120 lands within a tight cluster: it matches the AMD Ryzen 5 5600X3D at a 0% delta, trails the Intel Core i7-11700KF by 0.2%, leads the Intel Core i5-13400F by 0.3%, and trails the AMD Ryzen 7 7840U by 0.3%. These deltas are effectively negligible, indicating that the Core 5 120 performs at parity with a well-known set of mid-range desktop and mobile parts.

For the Qualcomm Snapdragon X2E-78-100, the absence of benchmark data means no score-based wins or losses can be established. The database records its percentile at 50, which places it at the median of all tested CPUs, but without actual scores, no further quantitative interpretation is possible. The Intel part's 77th percentile clearly outranks the Qualcomm chip's 50th percentile, but this is a positional metric rather than a direct benchmark result.

Architecture Differences

The two processors diverge sharply in nearly every architectural parameter. The Intel Core 5 120 uses a Raptor Lake design on a 10 nm process at Intel's foundry, while the Qualcomm Snapdragon X2E-78-100 uses the Glymur codename on a 3 nm process fabricated by TSMC. The process node difference is substantial: 10 nm versus 3 nm, which typically implies significant differences in transistor density and power efficiency, though the database does not provide transistor counts for either chip.

Core counts favor the Qualcomm part. The Snapdragon X2E-78-100 has 12 cores and 12 threads, meaning it offers no simultaneous multithreading. The Intel Core 5 120 has 6 cores and 12 threads, using hyperthreading to reach the same thread count. Clock speeds also differ: the Qualcomm chip has a 4.00 GHz base clock with no recorded boost clock, while the Intel part has a 2.50 GHz base clock and a 4.50 GHz boost clock. The Intel chip's boost capability is notable, but the Qualcomm part's higher base clock suggests a different performance profile.

Cache hierarchies are structured differently. The Intel Core 5 120 uses per-core L1 cache at 80 KB per core, per-core L2 at 1.25 MB per core, and a shared 18 MB L3 cache. The Snapdragon X2E-78-100 has 288 KB of L1 per core, a shared 16 MB L2, and no recorded L3 cache. The total cache footprint differs in organization: Intel concentrates L2 per core and adds a large shared L3, while Qualcomm uses a larger per-core L1 and a shared L2 without L3.

Memory support diverges completely. The Intel chip supports DDR4 and DDR5 memory over a dual-channel bus, with no recorded memory bandwidth figure. The Qualcomm chip supports LPDDR5X memory over a dual-channel bus with a recorded memory bandwidth of 152.4 GB/s. Neither part supports ECC memory. PCIe capabilities are similar in generation but differ in lane count: the Intel part offers Gen 5 with 16 CPU lanes, while the Qualcomm part offers Gen 5 with 12 CPU lanes.

Integrated graphics differ as well. The Intel Core 5 120 uses UHD Graphics 730, while the Qualcomm Snapdragon X2E-78-100 uses an Adreno X2-85. The Intel part is a desktop processor on Intel Socket 1700 with a 65 W TDP, while the Qualcomm part is a mobile processor on Qualcomm BGA 2343 with no recorded TDP. The Intel chip has a die size of 163 mm², while the Qualcomm chip measures 220 mm². The Intel part is unlocked? The database records multiplierUnlocked as false for both. The Intel chip's launch MSRP is $211; the Qualcomm part has no recorded launch MSRP.

The Intel Core 5 120 belongs to the Core 5 (Raptor Lake Refresh) generation and was released in 2025. The Qualcomm Snapdragon X2E-78-100 belongs to the Snapdragon X2 (Elite) generation and was released in 2026. Both are marked as Active in production status.

The Verdict

The data supports a clear split: the Intel Core 5 120 is the only one of the two with measurable benchmark performance, and it ranks at the 77th percentile among all CPUs with an average score of 25362. The Qualcomm Snapdragon X2E-78-100 has no recorded benchmarks, an average score of 0, and sits at the 50th percentile. On the basis of recorded performance data alone, the Intel part is the only chip with evidence of competitive execution.

However, the architectural records tell a different story for different workloads. The Snapdragon X2E-78-100 has 12 cores versus the Intel chip's 6, and a 4.00 GHz base clock versus 2.50 GHz. Its 3 nm process and 152.4 GB/s memory bandwidth indicate a design aimed at sustained throughput in a mobile envelope. The Intel part counters with a 4.50 GHz boost clock, per-core L2 cache, and a shared 18 MB L3.

For desktop users requiring proven multi-threaded and single-threaded scores, the Intel Core 5 120 is the only option with numbers. Its nearest rival deltas show it trading blows with the AMD Ryzen 5 5600X3D, Intel Core i7-11700KF, Intel Core i5-13400F, and AMD Ryzen 7 7840U, all within 0.3% of its average score. That places it in a well-established performance tier.

For mobile users prioritizing core count, higher base clock, and memory bandwidth, the Snapdragon X2E-78-100 presents a different specification, but the database cannot confirm its real-world performance because no benchmark scores are recorded. The verdict from the data is therefore conditional: the Intel chip has demonstrated performance, while the Qualcomm chip has unverified capabilities.

Where Each One Wins

The Intel Core 5 120 wins in scenarios where recorded benchmark data matters. Its Cinebench R23 multicore score of 18255 and single-core score of 2577, along with a PassMark single-thread score of 3595, provide concrete evidence of performance. Its 77th percentile ranking and average score of 25362 place it above the median of all CPUs. The chip also offers a higher boost clock at 4.50 GHz, a larger shared L3 cache at 18 MB, and a desktop socket with a 65 W TDP. For users running desktop workloads that rely on proven multi-threaded and single-threaded execution, the data supports the Intel part.

The Qualcomm Snapdragon X2E-78-100 wins on architectural specifications that are absent from the Intel chip. It has 12 cores versus 6, a 4.00 GHz base clock versus 2.50 GHz, a 3 nm process versus 10 nm, and 152.4 GB/s memory bandwidth versus no recorded figure. Its 16 MB shared L2 cache and 288 KB per-core L1 cache indicate a different cache strategy. For mobile workloads where core count, base clock, and memory bandwidth are primary factors, the Qualcomm part's specification sheet is stronger. However, the lack of any benchmark scores means these advantages remain unverified in measured performance.

The Intel chip's nearest rival comparisons show it performing at parity with the AMD Ryzen 5 5600X3D, Intel Core i7-11700KF, Intel Core i5-13400F, and AMD Ryzen 7 7840U. This positions it as a consistent performer within a known tier. The Qualcomm part has no rival data, so its competitive standing cannot be assessed. In use cases where the database's measured results are the deciding factor, the Intel Core 5 120 is the only chip with wins to show.
