AMD Ryzen 7 5800XT vs Qualcomm Snapdragon X1P-66-100 Comparison

Head-to-Head Benchmarks

The recorded data contains a complete benchmark profile for the AMD Ryzen 7 5800XT, while the Qualcomm Snapdragon X1P-66-100 has no recorded benchmark scores in the database. This makes a direct numerical comparison impossible for any workload. The Ryzen 7 5800XT holds a percentile rank of 81 among all CPUs, while the Snapdragon X1P-66-100 sits at the 50th percentile. The average benchmark score for the AMD part is 29,879, whereas the Qualcomm part has an average score of zero in the database due to the absence of test results.

The Ryzen 7 5800XT delivers a single-thread score of 959 in 3dMark, with multi-thread scaling visible across the 2-thread, 4-thread, 8-thread, and max-thread tests at 1,879, 3,603, 6,141, and 7,680 respectively. The 16-thread test records 7,683, nearly identical to the max-thread result, indicating the processor reaches its peak throughput with all 16 threads active. In Cinebench, the R23 multi-core score reaches 23,794, with a single-core score of 3,359. The R20 multi-core result stands at 9,993, and the R15 multi-core at 2,398. Passmark tests show an integer math score of 93,942, floating point math at 53,808, and data compression at 352,002. The single-thread Passmark score is 3,535.

Without any benchmark entries for the Snapdragon X1P-66-100, the head-to-head comparison is limited to architectural and specification differences rather than measured performance. The database shows zero wins for either processor in head-to-head tests, which reflects the missing Qualcomm data rather than any actual performance parity.

Architecture Differences

The two processors come from different design philosophies and market segments. The AMD Ryzen 7 5800XT uses the Zen 3 architecture under the Vermeer codename, while the Qualcomm Snapdragon X1P-66-100 uses the Oryon codename in the Snapdragon X Plus generation. The AMD chip is built on a 7 nm process at TSMC with 4,150 million transistors on a 74 mm² die. The Qualcomm chip uses a 4 nm process, also at TSMC, though transistor count and die size are not recorded.

Core configurations differ significantly. The Ryzen 7 5800XT has 8 cores and 16 threads, while the Snapdragon X1P-66-100 has 10 cores and 10 threads, meaning the Qualcomm part lacks simultaneous multithreading. Base clocks are 3.80 GHz for AMD and 3.40 GHz for Qualcomm, with boost clocks at 4.80 GHz and 4.00 GHz respectively. The AMD processor carries a 105 W TDP, while the Qualcomm part is rated at 35 W, reflecting its mobile orientation.

Cache hierarchies are structured differently. The Ryzen 7 5800XT provides 64 KB of L1 cache per core, 512 KB of L2 per core, and 32 MB of shared L3 cache. The Snapdragon X1P-66-100 has 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3. This gives the AMD processor substantially more aggregate L3 capacity, while the Qualcomm part has a larger per-core L1 allocation.

Memory support also diverges. The Ryzen 7 5800XT uses DDR4 in a dual-channel configuration with 51.2 GB/s of bandwidth and supports ECC memory. The Snapdragon X1P-66-100 uses LPDDR5X in dual-channel with 135.2 GB/s of bandwidth and no ECC support. The Qualcomm part also integrates an Adreno X1-85 GPU, whereas the AMD processor has no integrated graphics. PCIe lanes differ as well, with the AMD chip offering Gen 4 with 20 lanes versus Gen 4 with 12 lanes for Qualcomm.

The Ryzen 7 5800XT fits the AMD Socket AM4, has an unlocked multiplier, and was released on 2024-07-30 with a launch MSRP of $249. The Snapdragon X1P-66-100 uses Qualcomm BGA 2073, has a locked multiplier, and was released on 2024-04-23. The AMD part is a desktop segment product, while the Qualcomm chip targets mobile.

Where Each One Wins

The Ryzen 7 5800XT shows clear strengths in multi-threaded workloads based on its benchmark results. The 16-thread 3dMark score of 7,683 and the Cinebench R23 multi-core result of 23,794 indicate strong scaling across all 16 threads. Passmark multithread scoring at 28,053, integer math at 93,942, and floating point math at 53,808 all point to sustained throughput in compute-heavy tasks. The 32 MB shared L3 cache and 4,150 million transistors support these results.

The Snapdragon X1P-66-100, despite having no benchmark scores, offers architectural advantages in specific areas based on its specification sheet. The 135.2 GB/s memory bandwidth is more than double the AMD part's 51.2 GB/s, which can benefit memory-bound applications. The LPDDR5X support and integrated Adreno X1-85 GPU give it capabilities for compact mobile systems where discrete components are impractical. The 35 W TDP makes it suitable for thin-and-light devices, while the 10-core configuration with larger L1 cache per core (288 KB versus 64 KB) may aid certain single-threaded latency-sensitive tasks.

The AMD processor wins on core count parity with multithreading, higher clock speeds, ECC memory support, unlocked multiplier for overclocking, and a larger L3 cache. The Qualcomm processor wins on power efficiency, memory bandwidth, integrated graphics, and process node advantage at 4 nm versus 7 nm.

The Verdict

The data presents an asymmetric comparison. The AMD Ryzen 7 5800XT has a full benchmark profile with strong multi-threaded results, an 81st percentile ranking, and an average benchmark score of 29,879. Its nearest rivals in the database include the AMD Ryzen 7 7840H with an average score of 29,868, the AMD Ryzen 7 8845HS and Ryzen 7 7840HS at 29,955, and the AMD Ryzen 5 9600X at 29,713. The 5800XT sits within 0.6 percent of these parts, confirming its competitive position among desktop and high-performance mobile processors.

The Qualcomm Snapdragon X1P-66-100 has no recorded benchmarks, an average score of zero, and a 50th percentile ranking. Its specifications indicate a mobile-focused design with lower power draw, higher memory bandwidth, and integrated graphics, but the database contains no measured performance evidence to validate its capabilities.

Users requiring a desktop processor for multi-threaded workloads, ECC memory support, or overclocking flexibility should select the AMD Ryzen 7 5800XT. The data supports its performance across Cinebench, 3dMark, and Passmark tests. Users needing a mobile processor with integrated graphics, lower power consumption, and higher memory bandwidth should consider the Qualcomm Snapdragon X1P-66-100, but they must accept that no benchmark data exists to quantify its performance relative to the AMD part. The absence of test results for the Qualcomm chip means any performance comparison rests entirely on architectural specifications rather than measured outcomes.
