Intel Core 5 315 vs Qualcomm Snapdragon X2E-78-100 Comparison

The Verdict

The recorded data presents an unusual comparison. The Intel Core 5 315 has a full suite of benchmark scores, while the Qualcomm Snapdragon X2E-78-100 has no recorded benchmark results in the database. This means the Intel part’s performance can be analyzed directly, but the Qualcomm part’s performance cannot be quantified from the available information. The Intel Core 5 315 sits at the 72nd percentile among all CPUs, with an average benchmark score of 18,188. Its nearest rivals include the AMD EPYC 9274F at 18,189 (delta 0%), the Intel Core i7-9700 at 18,180 (delta 0%), the Intel Core i7-1365U at 18,177 (delta 0.1%), and the AMD Ryzen 7 5700U at 18,176 (delta 0.1%). These deltas are essentially negligible, meaning the Intel part performs at parity with those established processors.

The Qualcomm Snapdragon X2E-78-100 has a percentile rank of 50 and an average benchmark score of 0, which reflects the absence of test data rather than actual performance. The database shows no head-to-head benchmarks between the two, and no wins for either side. Therefore, the verdict is strictly one-sided: the Intel Core 5 315 is the only part with measured performance data, and the Qualcomm part’s capabilities remain unverified. Users requiring immediate, quantified performance should select the Intel part. Users considering the Qualcomm part must rely on its architectural specifications alone, as the database provides no evidence of its speed.

Architecture Differences

The two processors diverge significantly in their core configurations, foundries, memory pathways, and integrated graphics. The Intel Core 5 315 uses 6 cores and 6 threads, while the Qualcomm Snapdragon X2E-78-100 doubles that to 12 cores and 12 threads. The Intel part has a base clock of 1.50 GHz and a boost clock of 4.40 GHz. The Qualcomm part has a base clock of 4.00 GHz with no boost clock listed. Both are fabricated on a 3 nm process, but Intel uses its own foundry, while Qualcomm relies on TSMC. The Qualcomm die size is recorded as 220 mm²; the Intel die size is not in the database.

Cache hierarchies differ markedly. The Intel Core 5 315 has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Qualcomm Snapdragon X2E-78-100 has 288 KB of L1 cache per core, which is a per-core figure rather than a total, and 16 MB of shared L2 cache; no L3 cache is listed. Memory support also separates them. Intel supports both DDR5 and LPDDR5X over a single-channel memory bus, yielding 59.7 GB/s of bandwidth. Qualcomm supports only LPDDR5X but over a dual-channel bus, delivering 152.4 GB/s. Neither part supports ECC memory. PCIe connectivity differs as well: Intel provides Gen 4 with 6 lanes (CPU only), while Qualcomm provides Gen 5 with 12 lanes (CPU only). Integrated graphics are Intel Xe3 Graphics with 2 Xe cores on the Intel side, versus Adreno X2-85 on the Qualcomm side. The Intel part has a launch MSRP of $340; the Qualcomm part has no launch MSRP recorded. Both are active mobile parts, with the Intel releasing on 2026-04-15 and the Qualcomm on 2026-04-05.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors. The headToHeadBenchmarks array is empty, and both winsA and winsB are zero. This absence of comparative data makes a direct performance walkthrough impossible. The Intel Core 5 315, however, has standalone scores that can be interpreted against its nearest rivals. In Cinebench R23, the Intel part scores 12,981 in multicore and 1,832 in single-core. In Cinebench R20, it scores 5,452 multicore and 769 single-core. In Cinebench R15, it scores 1,308 multicore and 184 single-core. These results place it at parity with the AMD EPYC 9274F, Intel Core i7-9700, Intel Core i7-1365U, and AMD Ryzen 7 5700U, all within a 0.1% delta of each other.

PassMark tests show a wide spread. The Intel part scores 146,143 in data compression, 11,119 in data encryption, 13,143 in extended instructions, 112 in find prime numbers, 42,441 in floating point math, 31,690 in integer math, 15,272 in multithread, 1,163 in physics, 17,551 in random string sorting, and 4,021 in single-thread (with a duplicate entry also at 4,021). These numbers indicate strong integer and floating point throughput, but the lack of Qualcomm data means no comparative statement can be made. The only valid conclusion is that the Intel part’s measured performance matches its closest rivals, while the Qualcomm part has no measured performance to discuss.

Where Each One Wins

Based strictly on the recorded data, the Intel Core 5 315 wins in every category where a win can be assigned, because it has measurable benchmark results and the Qualcomm part has none. The Intel part’s percentile rank of 72 versus the Qualcomm part’s rank of 50 further reinforces this, though the latter rank is based on zero scores. The Intel part also has a confirmed launch MSRP of $340, which is a factual data point, while the Qualcomm part has no MSRP listed.

The Qualcomm Snapdragon X2E-78-100 wins on architectural specifications alone. It has twice the cores and threads (12 versus 6), a higher base clock (4.00 GHz versus 1.50 GHz), a larger shared L2 cache (16 MB versus 2.5 MB), a dual-channel memory bus with more than double the bandwidth (152.4 GB/s versus 59.7 GB/s), and PCIe Gen 5 with 12 lanes versus Gen 4 with 6 lanes. Its die size is recorded at 220 mm², which is a physical attribute, not a performance metric. These specification advantages, however, do not translate into benchmark wins because no benchmark data exists for the Qualcomm part.

For users who prioritize measured performance, the Intel Core 5 315 is the only choice with evidence. For users who prioritize core count, memory bandwidth, and PCIe generation, the Qualcomm part has the superior listed specifications. The database does not support any conclusion about the Qualcomm part’s real-world speed.

Both parts are active, mobile, non-unlocked, non-ECC processors on a 3 nm process. The Intel part supports both DDR5 and LPDDR5X, while the Qualcomm part supports only LPDDR5X. The Qualcomm part’s 12-core configuration and dual-channel memory pathway provide a structural advantage on paper, but the absence of any benchmark results leaves its actual performance unknown. The Intel part’s 6-core, single-channel design is fully characterized by the database, making it the only part with verifiable performance data.
