AMD Ryzen 5 PRO 8640U vs Qualcomm Snapdragon X1P-64-100 Comparison

The Verdict

The recorded data positions the AMD Ryzen 5 PRO 8640U as the significantly stronger processor for raw performance. Its average benchmark score of 30254 places it in the 81st percentile of all CPUs, while the Qualcomm Snapdragon X1P-64-100 sits at the 50th percentile with an average benchmark score of zero, indicating no recorded benchmark results in the database. The AMD part delivers 6 cores and 12 threads, while the Qualcomm offers 10 cores and 10 threads, yet the AMD chip's benchmark suite shows substantial measured output across Cinebench and Passmark workloads. For any workload requiring verified multi-threaded performance, the AMD Ryzen 5 PRO 8640U is the only option with data supporting its capabilities. The Snapdragon X1P-64-100, despite its higher core count, has no measured scores to validate its performance profile, making it unquantifiable in this comparison.

The AMD chip also offers practical advantages in platform compatibility. It uses AMD Socket FP7 with a 28 W TDP, whereas the Snapdragon requires Qualcomm BGA 2073 with a 35 W TDP. The AMD part supports ECC memory and DDR5, while the Snapdragon lacks ECC support and uses LPDDR5X. The AMD processor's 4 nm TSMC process node, 25,000 million transistors, and 178 mm² die size are recorded, while the Snapdragon's transistor count and die size are absent from the data. The AMD processor is the clear choice for users who need verified performance data, established x86 software compatibility through Zen 4 architecture, and lower power draw. The Snapdragon's role in this comparison is limited by the absence of any benchmark measurements, so it cannot be recommended based on the current database record.

Architecture Differences

The AMD Ryzen 5 PRO 8640U is built on the Zen 4 architecture with the codename Hawk Point, part of the 8000 series and the Ryzen 5 generation. It uses a 4 nm process node from TSMC, integrates 25,000 million transistors on a 178 mm² die, and features 6 cores with 12 threads. Its cache hierarchy consists of 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The base clock is 3.50 GHz with a boost clock of 4.90 GHz, and the TDP is rated at 28 W.

The Qualcomm Snapdragon X1P-64-100 uses the Oryon codename, part of the Snapdragon X (Plus) generation. It also uses a 4 nm TSMC process node, but its transistor count and die size are not recorded in the database. It has 10 cores and 10 threads, meaning no simultaneous multithreading. The base clock is 3.40 GHz with no boost clock recorded. The cache configuration differs substantially: 288 KB L1 per core, 12 MB L2 per module, and 6 MB shared L3. The TDP is 35 W.
