Where Each One Wins

The benchmark data in this database is one-sided for this comparison, as the Qualcomm Snapdragon X1P-66-100 has no recorded benchmark scores. All performance measurements come from the AMD Ryzen 5 PRO 5655G, which has 17 benchmark entries across Cinebench and Passmark suites.

For desktop productivity workloads, the AMD Ryzen 5 PRO 5655G shows strength in multi-threaded tasks. Its Cinebench R23 multi-core score of 17,249 and Passmark multithread score of 19,129 indicate solid rendering and parallel processing capability for a 6-core part. The single-core scores are also competitive: 2,435 in Cinebench R23 single-core and 3,241 in Passmark single-thread, which positions it well for everyday responsive tasks.

The Qualcomm Snapdragon X1P-66-100, by contrast, has no recorded benchmark results in the database. Its 10 cores and 10 threads suggest potential in multi-threaded workloads, but without measured data, its performance relative to the AMD part cannot be quantified. The Qualcomm chip's lower TDP of 35 W and mobile market segment indicate a design focus on power efficiency rather than raw throughput, but the database lacks scores to confirm any win in efficiency-oriented scenarios.

The AMD processor's percentile rank of 80 among all CPUs places it in the upper tier of processors tested in this database. The Qualcomm chip sits at the 50th percentile, though this ranking may reflect incomplete data rather than actual performance parity. The wins are entirely on the AMD side for measured benchmarks, while the Qualcomm side has no verified victories in the recorded data.

Architecture Differences

The AMD Ryzen 5 PRO 5655G is based on the Zen 3 architecture, codenamed Cezanne, and belongs to the Ryzen 5 generation within the 5000 series. It uses a 7 nm process from TSMC, with a transistor count of 10,700 million and a die size of 180 mm². The cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of L3 shared across the chip.

The Qualcomm Snapdragon X1P-66-100 uses the Oryon codename and belongs to the Snapdragon X generation, specifically the Plus variant. It is built on TSMC's 4 nm process node. Its cache structure is notably different: 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3. The L2 configuration suggests a modular layout where groups of cores share a larger L2 pool, unlike the AMD design which gives each core a dedicated 512 KB L2.

The AMD processor supports ECC memory, a feature absent on the Qualcomm part. Memory technology also diverges: the AMD chip uses DDR4, while the Qualcomm chip uses LPDDR5X, which is optimized for lower power in mobile environments. The memory bandwidth difference is substantial, with the Qualcomm part reaching 135.2 GB/s versus 51.2 GB/s for the AMD chip, a gap that reflects the newer memory standard.

PCIe capabilities differ as well. The AMD Ryzen 5 PRO 5655G provides PCIe Gen 3 with 16 lanes from the CPU. The Qualcomm Snapdragon X1P-66-100 offers PCIe Gen 4 with 12 lanes. The newer PCIe generation on the Qualcomm side provides higher per-lane bandwidth, though the AMD part has more total lanes.

The AMD chip uses the AMD Socket AM4, a standard desktop socket that allows for broad motherboard compatibility. The Qualcomm chip uses Qualcomm BGA 2073, a ball-grid array package typical of mobile soldered processors. This difference in socket type reflects their different market segments: desktop for AMD, mobile for Qualcomm.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons are impossible in this database because the Qualcomm Snapdragon X1P-66-100 has no recorded scores. The head-to-head benchmark array is empty, and the win counts for both processors are zero. All performance data belongs exclusively to the AMD Ryzen 5 PRO 5655G.

The AMD processor's Cinebench scores show a consistent pattern. In Cinebench R15, it records 1,738 for multi-core and 245 for single-core. In Cinebench R20, the scores are 7,244 multi-core and 1,022 single-core. Cinebench R23 yields 17,249 multi-core and 2,435 single-core. These results indicate a multi-core advantage that scales with the workload intensity, roughly doubling from R15 to R23, while single-core scores scale modestly.

The Passmark suite provides additional detail on the AMD chip's capabilities. The multithread score is 19,129, while the single-thread score is 3,241. In specific math workloads, the integer math score reaches 67,561, floating point math reaches 38,649, and extended instructions score 17,944. The data compression score is 255,608, random string sorting scores 25,253, and data encryption scores 15,253. The find prime numbers test scores 49, and the physics test scores 686.

For context, the AMD Ryzen 5 PRO 5655G holds an average benchmark score of 28,032 across all its tested workloads. Its nearest rivals in the database include the AMD Ryzen 5 PRO 8500GE with an average score of 28,054, a delta of -0.1%, and the Intel Core i9-12900H with an average score of 28,003, a delta of 0.1%. The Intel Core i5-14500T scores 28,065, a delta of -0.1%, and the AMD Ryzen AI 5 435 scores 28,128, a delta of -0.3%. These deltas place the AMD Ryzen 5 PRO 5655G within a tight 0.4% band of its closest competitors, indicating that its measured performance is closely matched by those four processors.

The Qualcomm Snapdragon X1P-66-100, with no benchmark scores, has an average benchmark score of 0 and no nearest rivals recorded. Its 50th percentile ranking among all CPUs in the database reflects the absence of measured performance data, not a verified performance level. The AMD part's 80th percentile ranking is based on its full set of recorded scores.

Given the missing data for the Qualcomm chip, the analysis must conclude that the AMD Ryzen 5 PRO 5655G is the only processor in this comparison with verified benchmark results. The Qualcomm Snapdragon X1P-66-100 presents a specification profile with higher core count, newer process node, faster memory bandwidth, and lower TDP, but the database contains no scores to validate its performance in actual workloads. The AMD chip's measured results show a capable desktop processor with strong multi-threaded output and a competitive standing among its nearest rivals.
