AMD Ryzen 5 5500X3D vs Qualcomm Snapdragon X2E-78-100 Comparison

Head-to-Head Benchmarks

The data available for this comparison is limited to a single side. The AMD Ryzen 5 5500X3D has a full set of PassMark benchmark records, while the Qualcomm Snapdragon X2E-78-100 has no recorded benchmark scores in the database. Consequently, a direct head-to-head numerical comparison across identical tests is not possible from the recorded data.

The AMD Ryzen 5 5500X3D posts an average benchmark score of 37018. This places it at the 85th percentile of all CPUs in the database. Its nearest rivals in the database include the AMD Ryzen 5 5600F with an average score of 36945, which is a 0.2% delta, and the Intel Core Ultra 5 225 with an average score of 36938, also a 0.2% delta. The AMD Ryzen AI 7 PRO 450 scores 37093, a -0.2% delta relative to the 5500X3D, and the Intel Core i9-12900T scores 37112, a -0.3% delta. These figures indicate that the 5500X3D sits in a tightly packed performance band, effectively trading places with these rivals within a fraction of a percent.

Looking at individual benchmark workloads for the 5500X3D, the strongest results appear in data compression with a score of 230392, and integer math with a score of 60033. Floating point math delivers 34511, and extended instructions score 15925. Data encryption records 13967, while random string sorting scores 23675. The multithread score is 20363, and the single-thread score is 2941. Physics performance records 2282, and find prime numbers scores 170.

Because the Qualcomm Snapdragon X2E-78-100 has no benchmark entries, its performance cannot be quantified against the AMD part. The database records its percentile as 50 and its average benchmark score as 0, which reflects the absence of data rather than an actual performance result.

The Verdict

The database contains no recorded performance measurements for the Qualcomm Snapdragon X2E-78-100. The AMD Ryzen 5 5500X3D has a complete benchmark profile, an average score of 37018, and an 85th percentile ranking. Any performance-based selection between these two parts can only be made for the AMD processor, since the Qualcomm part lacks any measured data.

The Ryzen 5 5500X3D is a desktop processor with a 105 TDP, designed for AMD Socket AM4. The Snapdragon X2E-78-100 is a mobile processor using Qualcomm BGA 2343, with no TDP recorded. These are fundamentally different market segments. The data supports choosing the AMD part where verified benchmark results are required. The Qualcomm part has no data to support a performance claim.

Where Each One Wins

The AMD Ryzen 5 5500X3D wins in the only category where measured data exists: verified performance. Its average benchmark score of 37018 places it at the 85th percentile of all CPUs, and its individual benchmarks cover data compression, encryption, integer math, floating point math, and multithread workloads. Desktop users on AMD Socket AM4 with DDR4 memory and ECC support can rely on these recorded results.

The Qualcomm Snapdragon X2E-78-100 wins on specification-level attributes recorded in the database. It has more cores (12 versus 6), a higher base clock (4.00 GHz versus 3.00 GHz), a smaller process node (3 nm versus 7 nm), higher memory bandwidth (152.4 GB/s versus 51.2 GB/s), PCIe Gen 5 versus Gen 4, and integrated graphics. Its mobile market segment and LPDDR5X memory support indicate a platform designed for portable systems, though no benchmark data exists to confirm actual performance.

The AMD part is the only one of the two with any recorded benchmark results, making it the only processor in this comparison with measurable performance evidence. The Snapdragon part remains an unverified entry in the database, with its 50th percentile ranking reflecting no data rather than a computed standing.
