AMD Ryzen 5 3501U vs Qualcomm Snapdragon X2E-78-100 Comparison

Head-to-Head Benchmarks

The database currently lists no direct head-to-head benchmark comparisons between the AMD Ryzen 5 3501U and the Qualcomm Snapdragon X2E-78-100. The head-to-head results array is empty, and neither processor records any wins in direct matchups. However, the available individual benchmark data for the AMD Ryzen 5 3501U provides a useful baseline for understanding its measured performance profile, while the Qualcomm part has no recorded benchmark scores in the database at this time.

For the AMD Ryzen 5 3501U, the recorded PassMark results show a multi-thread score of 7071 and a single-thread score of 2136. Its strongest relative showing comes in data compression, where it scores 87380, and integer math, where it records 26321. Floating point math reaches 12707, while random string sorting posts 10414. The extended instructions test yields 3274, and data encryption produces 5580. The find prime numbers test records a score of 21, and the physics test registers 483. These figures place the Ryzen 5 3501U at the 69th percentile among all CPUs in the database, with an average benchmark score of 14320.

The Qualcomm Snapdragon X2E-78-100 has no benchmark scores recorded in the database. Its percentile versus all CPUs stands at 50, and its average benchmark score is listed as zero. This means any head-to-head comparison must rely on architectural specifications rather than measured performance data. The absence of scores for the Qualcomm part makes direct numerical comparisons impossible; the analysis must instead focus on what each processor brings to the table in terms of design, memory support, and connectivity.

Architecture Differences

The two processors diverge sharply in almost every architectural dimension. The AMD Ryzen 5 3501U belongs to the 3000 series and uses the Picasso codename, built on the Zen+ microarchitecture. It is manufactured on a 12 nm process at GlobalFoundries, with 4,940 million transistors on a 210 mm² die. The Qualcomm Snapdragon X2E-78-100, by contrast, uses the Glymur codename and belongs to the Snapdragon X2 series under the Elite generation. It is fabricated on a 3 nm process at TSMC, with a die size of 220 mm². The transistor count for the Qualcomm part is not recorded in the database.

Core and thread counts differ substantially. The AMD processor has 4 cores and 4 threads, meaning it does not use simultaneous multithreading. The Qualcomm processor has 12 cores and 12 threads, tripling the core count. Clock speeds also diverge: the AMD part runs at a base clock of 2.10 GHz and a boost clock of 3.70 GHz. The Qualcomm part has a base clock of 4.00 GHz, while its boost clock is not listed in the database. The AMD processor carries a TDP of 15 watts; the Qualcomm processor has no TDP value recorded.

Cache hierarchies are structured very differently. The AMD Ryzen 5 3501U provides 96 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The Qualcomm Snapdragon X2E-78-100 provides 288 KB of L1 per core and 16 MB of shared L2 cache, with no L3 cache listed. This means the Qualcomm part relies on a much larger L2 pool shared across all 12 cores, while the AMD part uses a more conventional per-core L1 and L2 arrangement with a separate shared L3 tier.

Memory support further separates the two. The AMD processor uses DDR4 memory on a dual-channel bus with a memory bandwidth of 38.4 GB/s. The Qualcomm processor uses LPDDR5X memory on a dual-channel bus with a memory bandwidth of 152.4 GB/s, which is roughly four times higher. Neither processor supports ECC memory. PCIe connectivity also differs: the AMD part uses PCIe Gen 3, while the Qualcomm part uses PCIe Gen 5 with 12 lanes available to the CPU only.

Integrated graphics present another clear distinction. The AMD Ryzen 5 3501U includes Radeon Vega 8 graphics, while the Qualcomm Snapdragon X2E-78-100 includes Adreno X2-85 graphics. Both target the mobile market segment, and both are listed as active in production. The AMD processor uses the AMD Socket FP5, while the Qualcomm processor uses Qualcomm BGA 2343. Neither processor has an unlocked multiplier. The AMD part numbers as YM3501C4T4MFG, and the Qualcomm part numbers as X2E78100.

Where Each One Wins

Given the lack of direct benchmark results for the Qualcomm Snapdragon X2E-78-100, any assessment of where each processor wins must derive from architectural characteristics and the recorded scores of the AMD part.

The AMD Ryzen 5 3501U demonstrates measurable strengths in the database. Its average benchmark score of 14320 places it at the 69th percentile among all CPUs, which indicates solid performance relative to the broader field. Its nearest rivals in the database include the AMD Ryzen Embedded V2546 with an average score of 14336 and a delta of -0.1 percent, the AMD Ryzen 3 7320C with an average score of 14277 and a delta of 0.3 percent, the Intel Core 7 160UL with an average score of 14232 and a delta of 0.6 percent, and the Intel Core i5-10400F with an average score of 14185 and a delta of 1 percent. This places the Ryzen 5 3501U within a narrow performance band around those processors, within roughly one percentage point of each.

The Qualcomm Snapdragon X2E-78-100, with no recorded benchmarks, cannot claim any measured wins in the database. Its architectural advantages are clear on paper: 12 cores versus 4, a 4.00 GHz base clock versus 2.10 GHz, 16 MB of shared L2 versus 4 MB of shared L3 plus per-core L2, and 152.4 GB/s of memory bandwidth versus 38.4 GB/s. The 3 nm process node also suggests a more modern manufacturing approach compared to the 12 nm node of the AMD part. These specifications indicate that the Qualcomm processor would likely outperform the AMD processor in heavily threaded workloads and memory-bandwidth-sensitive tasks, but the database contains no measured scores to confirm this.

For the AMD processor, the recorded benchmark results show particular strengths in data compression, where the score of 87380 far exceeds its other results, and integer math at 26321. The single-thread score of 2136 and multi-thread score of 7071 indicate moderate performance for a 4-core, 4-thread part. The physics score of 483 and the find prime numbers score of 21 are lower relative to the other tests, suggesting weaker performance in those specific workloads.

The Verdict

The recorded data points in one clear direction. The AMD Ryzen 5 3501U has a full set of benchmark scores, an average score of 14320, and a 69th percentile ranking. The Qualcomm Snapdragon X2E-78-100 has no benchmark scores at all, an average score of zero, and a 50th percentile ranking that appears based on incomplete information.

For users selecting between these two mobile processors, the AMD Ryzen 5 3501U offers verified performance across a range of tests, including data compression, integer math, and floating point math. Its 15 watt TDP and dual-channel DDR4 support with 38.4 GB/s bandwidth define a modest power envelope. The Qualcomm Snapdragon X2E-78-100 promises substantially higher theoretical capability through 12 cores, a 4.00 GHz base clock, 16 MB of shared L2 cache, and 152.4 GB/s of LPDDR5X bandwidth, but the database cannot confirm any of that promise with measured results.

The choice depends on whether the user prioritizes verified performance or unverified specifications. The AMD part delivers known results at the 69th percentile, with nearest rivals within one percentage point of its average score. The Qualcomm part, despite its architectural advantages on paper, presents no data to substantiate its capabilities. In the absence of benchmarks for the Qualcomm processor, the AMD Ryzen 5 3501U stands as the only option with measurable performance evidence in the database.
