AMD Ryzen 5 PRO 5655G vs Qualcomm Snapdragon X1E-78-100 Comparison

Where Each One Wins

The AMD Ryzen 5 PRO 5655G and Qualcomm Snapdragon X1E-78-100 occupy different performance classes, and the recorded data makes the split clear. The Ryzen 5 PRO 5655G has a full benchmark suite in the database, with scores across Cinebench R15, R20, R23, and PassMark workloads. The Snapdragon X1E-78-100 has no recorded benchmark scores, no average score, and no nearest rival data. This means every measurable performance comparison in the database currently favors the AMD part by default, simply because it has data and the Qualcomm part does not.

The Ryzen 5 PRO 5655G achieves an average benchmark score of 28032, which places it at the 80th percentile among all CPUs in the database. Its nearest rivals include the AMD Ryzen 5 PRO 8500GE at 28054 (0.1% higher), the Intel Core i5-14500T at 28065 (0.1% higher), the Intel Core i9-12900H at 28003 (0.1% lower), and the AMD Ryzen AI 5 435 at 28128 (0.3% higher). These deltas are all within a fraction of a percent, indicating the Ryzen 5 PRO 5655G sits in a tightly clustered performance tier.

The Snapdragon X1E-78-100, by contrast, shows a 50th percentile ranking and an average benchmark score of zero. Without recorded measurements, the database cannot confirm any workload where the Qualcomm part wins. The AMD processor wins in every category where data exists: multi-core rendering, single-core rendering, integer math, floating-point math, encryption, compression, and physics.

For use-case splits, the Ryzen 5 PRO 5655G is the only option with demonstrated strengths. Its single-core Cinebench R23 score of 2435 and multi-core score of 17249 indicate strong desktop-oriented performance. The Snapdragon X1E-78-100 may target mobile efficiency with its 35 W TDP, but the database holds no benchmark evidence of its capabilities.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 PRO 5655G uses the Zen 3 architecture, code-named Cezanne, built on TSMC's 7 nm process. The Qualcomm Snapdragon X1E-78-100 uses the Oryon codename, built on TSMC's 4 nm process. Both use TSMC as the foundry, but the node difference is significant: 7 nm versus 4 nm.

Core counts differ substantially. The AMD part has 6 cores and 12 threads, while the Qualcomm part has 12 cores and 12 threads. The Snapdragon has no simultaneous multithreading, so its 12 cores map directly to 12 threads. The Ryzen 5 PRO 5655G uses SMT to double its 6 physical cores into 12 logical threads.

Cache hierarchies are structured very differently. The Ryzen 5 PRO 5655G has 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The Snapdragon X1E-78-100 has 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3. The Qualcomm part has more total L1 and L2 capacity, while the AMD part has more L3.

Clock behavior diverges as well. The AMD processor has a base clock of 3.90 GHz and a boost clock of 4.40 GHz. The Snapdragon has a base clock of 3.40 GHz but no recorded boost clock in the database. The AMD part has a 65 W TDP, while the Snapdragon draws 35 W. The Qualcomm part is clearly designed for lower power consumption, though the database lacks benchmark data to show the performance trade-off.

Memory interfaces differ sharply. The Ryzen 5 PRO 5655G supports DDR4 memory on a dual-channel bus with 51.2 GB/s bandwidth and ECC support. The Snapdragon X1E-78-100 supports LPDDR5X on a dual-channel bus with 135.2 GB/s bandwidth and no ECC. The Qualcomm part has over 2.6 times the memory bandwidth on paper, which could matter for integrated graphics or data-heavy workloads, but no benchmark confirms this advantage.

PCIe connectivity also differs. The AMD part uses PCIe Gen 3 with 16 lanes (CPU only). The Snapdragon uses PCIe Gen 4 with 12 lanes (CPU only). The Qualcomm part has newer PCIe generation support but fewer lanes.

The Ryzen 5 PRO 5655G uses the AMD Socket AM4, while the Snapdragon uses Qualcomm BGA 2073. The AMD part is a desktop processor; the Snapdragon is a mobile processor. The AMD part has a Radeon Vega 7 integrated GPU, while the Snapdragon has an Adreno X1-85.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for this pair, and the Snapdragon X1E-78-100 has no individual benchmark scores recorded. The comparison therefore rests entirely on the AMD processor's measured results and the absence of Qualcomm measurements.

The Ryzen 5 PRO 5655G records a Cinebench R23 multi-core score of 17249 and a single-core score of 2435. In Cinebench R20, it scores 7244 multi-core and 1022 single-core. In Cinebench R15, it scores 1738 multi-core and 245 single-core. These scores place the AMD part in the 80th percentile of all CPUs.

PassMark results for the Ryzen 5 PRO 5655G show 67561 in integer math, 38649 in floating-point math, 255608 in data compression, and 15253 in data encryption. The processor also records 17944 in extended instructions, 25253 in random string sorting, and 686 in physics. Its PassMark single-thread score is 3241, and its multithread score is 19129.

The nearest rival data confirms the Ryzen 5 PRO 5655G sits in a competitive band. The AMD Ryzen 5 PRO 8500GE scores 28054, just 0.1% higher. The Intel Core i5-14500T scores 28065, also 0.1% higher. The Intel Core i9-12900H scores 28003, 0.1% lower. The AMD Ryzen AI 5 435 scores 28128, 0.3% higher. The Ryzen 5 PRO 5655G trails the top rival in this group by only 0.3%, a negligible margin.

Because the Snapdragon X1E-78-100 has no scores, the database cannot produce any win for it. The Ryzen 5 PRO 5655G leads in every measured category by default, which is a meaningful statement: the Qualcomm part has no recorded evidence of performance in this database.

The Verdict

The data supports only one selection: the AMD Ryzen 5 PRO 5655G. It has a complete benchmark profile, a strong 80th percentile ranking, and an average score of 28032. The Qualcomm Snapdragon X1E-78-100 has no benchmark scores, no average score, and no nearest rivals, leaving its performance unverified in the database.

For desktop use, the Ryzen 5 PRO 5655G is the clear choice based on recorded measurements. Its 6 cores and 12 threads, 4.40 GHz boost clock, and 65 W TDP suit a desktop AM4 platform. Its DDR4 memory support with ECC and 51.2 GB/s bandwidth provide a conventional, reliable memory path. The Zen 3 architecture on a 7 nm process delivers the benchmark results shown above.

The Snapdragon X1E-78-100 may appeal to mobile or low-power scenarios. Its 35 W TDP is roughly half the AMD part's 65 W TDP. Its 12 cores and 135.2 GB/s memory bandwidth are notable on paper. Its 4 nm process and LPDDR5X support indicate a modern, efficient design. But without benchmark data, the database cannot verify any of these advantages in practice.

The Ryzen 5 PRO 5655G also benefits from a known competitive position. Its nearest rivals are all within 0.3% of its average score, meaning it trades blows with recent Intel Core and AMD processors. The Snapdragon X1E-78-100 has no comparable positioning data.

The verdict is straightforward: the AMD Ryzen 5 PRO 5655G is the only processor in this comparison with measurable performance, and it performs at the 80th percentile. The Qualcomm Snapdragon X1E-78-100 remains an unquantified entry in the database, suitable only for analysis once benchmark results are recorded. Until then, the AMD part wins every comparison by default.
