AMD Ryzen 5 7500X3D vs Qualcomm Snapdragon X2E-78-100 Comparison

The Verdict

The AMD Ryzen 5 7500X3D is a desktop processor built around a 6-core, 12-thread configuration with a 65 W TDP. Its recorded data shows a PassMark average benchmark score of 44,573, placing it in the 89th percentile of all CPUs in the database. The Qualcomm Snapdragon X2E-78-100 is a mobile chip with 12 cores and 12 threads, a 3 nm process node, and a 50th percentile standing, but it has no recorded benchmark scores and an average score of zero. The data indicates that the AMD part is the only one of the two with measurable performance data, so any selection based on benchmark results must favor the Ryzen 5 7500X3D.

For users whose workloads rely on established x86 desktop software, the AMD processor is the clear choice from the recorded metrics. Its 96 MB of shared L3 cache and 5 nm process node, paired with a 4.50 GHz boost clock, position it as a capable desktop part. The Qualcomm chip, by contrast, targets the mobile segment with a 3 nm node and 152.4 GB/s memory bandwidth, but without any benchmark scores in the database, its performance cannot be quantified. The data shows no head-to-head benchmark wins for either part, and the Qualcomm part has zero wins recorded, which further emphasizes that the AMD processor is the only one with substantiated performance.

The verdict from the data is straightforward: the AMD Ryzen 5 7500X3D is the only chip with measurable results, so it is the one to choose for any performance-sensitive application. The Qualcomm Snapdragon X2E-78-100 may appeal to mobile system designers due to its 12 cores and higher memory bandwidth, but the absence of scores means it cannot be recommended on the basis of benchmark data.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for these two processors, and the Qualcomm part has no individual benchmark scores at all. However, the AMD Ryzen 5 7500X3D has 11 recorded PassMark tests, and these scores can be interpreted against its nearest rivals to show where it stands.

The AMD chip's strongest recorded result is in data compression, where it scores 271,649. Its nearest rival, the Intel Core Ultra X9 388H, has an average score of 44,466, and the AMD chip is 0.2% ahead of that rival in average terms. The data compression score is the highest individual number in the AMD benchmark set, indicating a strong showing in compression workloads. In data encryption, the AMD chip scores 15,797, which is a lower figure but still reflects a specific workload result. The extended instructions test yields 20,455, and floating point math scores 43,594.

The single-thread score for the AMD chip is 3,494, which appears in two separate test entries with identical values. The multithread score is 25,047, and the integer math score is 70,774. The find prime numbers test returns 221, which is the lowest individual score, while random string sorting scores 32,999. The physics test scores 2,779.

Relative to its nearest rivals, the AMD Ryzen 5 7500X3D sits within a tight cluster. It is 0.2% ahead of the Intel Core Ultra X9 388H, 0.5% ahead of the Intel Core i9-13950HX, and 0.6% ahead of the AMD Ryzen AI Max 385. It trails the Intel Core i5-14600 by 0.7%. These deltas are small, meaning the AMD chip's average score of 44,573 is nearly identical to its closest competitors, with the largest gap being less than one percentage point in either direction.

Because the Qualcomm Snapdragon X2E-78-100 has no benchmark scores, no wins can be attributed to it. The AMD part has zero recorded wins in head-to-head comparisons as well, but its individual test scores provide the only quantitative performance data between the two. The data shows that the AMD chip's multithread score of 25,047 and its integer math score of 70,774 are substantial figures, while its single-thread score of 3,494 indicates moderate per-core performance. The 96 MB L3 cache likely contributes to the high data compression result, though the database does not explicitly link cache size to test outcomes. The Qualcomm chip's 16 MB shared L2 cache and 152.4 GB/s bandwidth suggest a memory-oriented design, but without scores, any performance claim remains unverified.
