AMD Ryzen 5 PRO 8640HS vs Qualcomm Snapdragon X1P-66-100 Comparison

AMD Ryzen 5 PRO 8640HS and Qualcomm Snapdragon X1P-66-100 are both active mobile processors released in April 2024, but they approach performance from fundamentally different architectures. The Ryzen 5 PRO 8640HS is a 6-core, 12-thread x86 part from AMD, while the Snapdragon X1P-66-100 is a 10-core, 10-thread ARM-based processor from Qualcomm. The database contains complete benchmark records for the AMD processor across a wide range of tests, while the Qualcomm processor has no recorded benchmark scores. This disparity in available data shapes the comparison.

Head-to-Head Benchmarks

The database does not contain any direct head-to-head benchmark comparisons between the AMD Ryzen 5 PRO 8640HS and the Qualcomm Snapdragon X1P-66-100. The `headToHeadBenchmarks` field is empty, meaning no paired test results exist for these two processors.

However, the AMD Ryzen 5 PRO 8640HS has an extensive set of individual benchmark scores recorded. Its average benchmark score is 28478, placing it at the 80th percentile of all CPUs in the database. The Qualcomm Snapdragon X1P-66-100 has no recorded benchmarks, an average score of 0, and sits at the 50th percentile by default.

Examining the AMD processor's recorded performance, its Cinebench R23 multi-core score is 18104, and its single-core score is 2555. In Cinebench R20, the multi-core score is 7603, with a single-core score of 1073. The Cinebench R15 results show 1824 multi-core and 257 single-core. PassMark results include a multi-thread score of 21465, a single-thread score of 3561, floating-point math at 43019, and integer math at 69839.

Without any recorded scores for the Snapdragon X1P-66-100, direct numerical comparisons are impossible. The AMD processor's data can be interpreted on its own merits, but any head-to-head analysis must rely on the architectural specifications rather than measured outcomes.

Where Each One Wins

For the AMD Ryzen 5 PRO 8640HS, the recorded benchmarks show clear strengths in multi-threaded workloads. The Cinebench R23 multi-core score of 18104 is over seven times the single-core score of 2555, indicating strong scaling across its 12 threads. PassMark multi-thread performance at 21465 similarly dwarfs the single-thread score of 3561. This suggests the processor handles parallel tasks such as video encoding, 3D rendering, and scientific computing effectively.

The Qualcomm Snapdragon X1P-66-100 has no benchmark data, so its wins cannot be quantified. Its specification profile points to different strengths. It offers a higher memory bandwidth of 135.2 GB/s compared to 89.6 GB/s for the AMD part, and it supports LPDDR5X memory rather than DDR5. The Snapdragon's cache hierarchy differs substantially, with 288 KB of L1 per core and 12 MB of L2 per module, though its 6 MB of shared L3 is smaller than the AMD's 16 MB shared L3. These differences suggest the Snapdragon may favor memory-bandwidth-intensive workloads, but no measured data confirms this.

The AMD processor also demonstrates strong single-thread performance with a PassMark single-thread score of 3561 and a Cinebench R23 single-core score of 2555. Its boost clock of 4.90 GHz is higher than the Snapdragon's 4.00 GHz boost, and its base clock of 3.50 GHz slightly exceeds the Snapdragon's 3.40 GHz base. These clock advantages give the AMD part an edge in latency-sensitive, lightly threaded applications based on the raw specifications.

Specification Differences

The two processors differ across nearly every major specification category. The AMD Ryzen 5 PRO 8640HS uses 6 cores and 12 threads, while the Qualcomm Snapdragon X1P-66-100 uses 10 cores and 10 threads. Clock speeds differ as well: the AMD part runs at 3.50 GHz base and 4.90 GHz boost, whereas the Qualcomm part runs at 3.40 GHz base and 4.00 GHz boost.

Thermal design power differs, with the AMD processor rated at 28 W and the Qualcomm at 35 W. The socket types are entirely different: AMD uses Socket FP7, while Qualcomm uses BGA 2073. Memory support also diverges, with the AMD supporting DDR5 and the Qualcomm supporting LPDDR5X. Memory bandwidth shows a significant gap, at 89.6 GB/s for the AMD versus 135.2 GB/s for the Qualcomm.

The AMD processor supports ECC memory, while the Qualcomm does not. PCIe lane counts differ, with the AMD offering Gen 4 with 20 lanes (CPU only) and the Qualcomm offering Gen 4 with 12 lanes (CPU only). Integrated graphics are different as well: the AMD uses Radeon 760M, while the Qualcomm uses Adreno X1-85. The AMD has a part number of 100-000001354 (FP7r2) or 100-000001382 (FP7), while the Qualcomm has part number X1P66100.

Architecture Differences

The AMD Ryzen 5 PRO 8640HS is built on the Zen 4 architecture with the codename Hawk Point, belonging to the 8000 series and Ryzen 5 generation. The Qualcomm Snapdragon X1P-66-100 uses the Oryon codename and belongs to the Snapdragon X (Plus) generation. Both are manufactured on a 4 nm process at TSMC, but the AMD processor reports 25,000 million transistors on a 178 mm² die size, while the Qualcomm processor has no recorded transistor count or die size.

Cache hierarchies are markedly different. The AMD processor has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Qualcomm processor has 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3. This means the AMD has a larger L3 cache, while the Qualcomm has substantially larger L1 and per-module L2 allocations.

The AMD processor's market segment is mobile, and it is produced by AMD. The Qualcomm processor's manufacturer is listed as "Unknown" in the database, though it is also a mobile processor. Both are active in production status, and neither has a launch MSRP recorded. Neither processor has an unlocked multiplier.

The Verdict

The data presents a lopsided comparison. The AMD Ryzen 5 PRO 8640HS has a complete set of benchmark results, an average score of 28478, and an 80th percentile ranking. The Qualcomm Snapdragon X1P-66-100 has no recorded benchmarks, an average score of 0, and a default 50th percentile ranking. Any user requiring measured performance data would select the AMD processor, as its performance is documented and verifiable.

The AMD processor's benchmark scores show substantial multi-threaded capability, with a Cinebench R23 multi-core score of 18104 and a PassMark multi-thread score of 21465. Its single-thread performance, with a PassMark score of 3561 and a Cinebench R23 single-core score of 2555, is also strong. The higher boost clock of 4.90 GHz supports these results.

The Qualcomm processor offers a different specification profile. Its higher memory bandwidth of 135.2 GB/s, larger core count of 10, and different cache layout may appeal to workloads that depend on memory throughput. However, without any benchmark data, no performance claims can be substantiated from the database.

For users relying on the database, the AMD Ryzen 5 PRO 8640HS is the only processor with measurable results. Its 80th percentile ranking and complete benchmark suite provide a clear performance picture. The Snapdragon X1P-66-100 remains an unmeasured quantity, and its specifications alone cannot bridge the absence of test data. The choice is straightforward: the AMD processor has proven results, while the Qualcomm processor does not.
