AMD Ryzen 5 PRO 8645HS vs Qualcomm Snapdragon X1P-66-100 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance advantage for the AMD Ryzen 5 PRO 8645HS across all measured workloads. The Qualcomm Snapdragon X1P-66-100 has no benchmark entries in the database, meaning direct numerical comparisons are only possible in one direction. The AMD processor delivers a Cinebench R23 multi-core score of 19742 and a single-core score of 2787. In Cinebench R20, it reaches 8291 multi-core and 1170 single-core. The older Cinebench R15 test shows 1989 multi-core and 280 single-core.

PassMark results further establish the AMD part's capabilities. The multi-thread score sits at 23569, while single-thread performance records 3858. Integer math completes at 72740, floating point math at 45481, and extended instructions at 21212. Data compression scores 265826, data encryption scores 17387, and random string sorting scores 35472. Prime number finding returns 73, and physics simulation scores 1208.

Because the Qualcomm Snapdragon X1P-66-100 has no recorded benchmarks, the database cannot assign any head-to-head wins to it. All wins in the comparison default to the AMD processor by virtue of having measurable results. The average benchmark score for the AMD part is 30879, placing it in the 82nd percentile of all CPUs. The Qualcomm chip sits in the 50th percentile with an average score of zero, reflecting the absence of test data. The nearest rivals to the AMD processor include the AMD Ryzen 7 8700F with an average score of 30746, the Intel Core i7-13700TE at 31028, the AMD Ryzen 9 8945HS at 31074, and the Intel Core i7-12700F at 31081. The AMD Ryzen 5 PRO 8645HS sits within 0.6% of all four of those parts, indicating it performs in the same tier as higher-tier desktop and mobile processors despite its lower core count.

Architecture Differences

The two processors diverge fundamentally in their architectural approach. The AMD Ryzen 5 PRO 8645HS uses the Zen 4 architecture under the Hawk Point codename, part of the 8000 series. It is built on a 4 nm process at TSMC with 25,000 million transistors on a 178 mm² die. The Qualcomm Snapdragon X1P-66-100 uses the Oryon codename, belongs to the Snapdragon X Plus generation, and is also fabricated on a 4 nm process at TSMC, though its transistor count and die size are not recorded in the database.

Core configuration differs sharply. The AMD chip has 6 cores and 12 threads, enabling simultaneous multithreading. The Qualcomm chip has 10 cores and 10 threads, meaning each core handles a single thread with no SMT support. Base clock speeds favor AMD at 4.30 GHz versus 3.40 GHz for Qualcomm. Boost clocks also favor AMD at 5.00 GHz versus 4.00 GHz. Thermal design power stands at 45 watts for AMD and 35 watts for Qualcomm, reflecting different power envelopes.

Cache layouts show distinct design philosophies. AMD allocates 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3. Qualcomm allocates 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3. The Qualcomm design concentrates more L2 capacity per module, while AMD spreads L2 across individual cores and provides a larger shared L3 pool.

Memory support also separates the two. AMD uses DDR5 with dual-channel configuration and a bandwidth of 89.6 GB/s. Qualcomm uses LPDDR5X with dual-channel configuration and a higher bandwidth of 135.2 GB/s. ECC memory support exists on the AMD part but is absent on the Qualcomm chip. PCIe lanes differ as well: AMD provides Gen 4 with 20 lanes, while Qualcomm provides Gen 4 with 12 lanes. Both integrate graphics, with AMD using the Radeon 760M and Qualcomm using the Adreno X1-85. The AMD processor uses the AMD Socket FP7, while Qualcomm uses the Qualcomm BGA 2073 socket. Neither chip has an unlocked multiplier.

The Verdict

The database contains only one side of the comparison. The AMD Ryzen 5 PRO 8645HS has a full suite of benchmark results, while the Qualcomm Snapdragon X1P-66-100 has none. This makes any performance verdict one-sided: the AMD processor demonstrably executes workloads with scores recorded across Cinebench and PassMark tests, while the Qualcomm processor's performance remains unmeasured in the database.

The AMD part's 82nd percentile standing among all CPUs confirms it sits above the median. Its average benchmark score of 30879 puts it within 0.6% of the Ryzen 7 8700F, Core i7-13700TE, Ryzen 9 8945HS, and Core i7-12700F. Those rivals are all higher-tier parts, which indicates the 6-core AMD chip competes effectively against chips with more cores or higher nominal positioning.

The Qualcomm chip's 50th percentile reflects its zero benchmark score rather than measured performance. Its 10 cores and 10 threads, higher memory bandwidth of 135.2 GB/s, and lower 35 watt TDP suggest a design aimed at efficiency, but the database cannot confirm how that translates into application performance. Until benchmark data exists for the Snapdragon X1P-66-100, the AMD Ryzen 5 PRO 8645HS stands as the only part in this comparison with verifiable performance metrics.

Users requiring a processor with documented multi-threaded and single-threaded capabilities should look at the AMD part. Users considering the Qualcomm chip should note that no performance measurements are available in the database, making direct comparisons impossible.

Where Each One Wins

The AMD Ryzen 5 PRO 8645HS wins in every category with recorded data. Its 12 threads versus 10 threads gives it an advantage in heavily threaded workloads that can utilize simultaneous multithreading. The Cinebench R23 multi-core score of 19742 demonstrates strong sustained multi-threaded throughput. The single-core score of 2787 in the same test shows that its 5.00 GHz boost clock translates into competitive single-thread responsiveness. PassMark integer math at 72740 and floating point math at 45481 indicate robust general-purpose compute capability. Data compression at 265826 and encryption at 17387 confirm that the AMD part handles real-world productivity tasks effectively.

The Qualcomm Snapdragon X1P-66-100 cannot be assigned wins in any category because the database contains no benchmark results for it. Its architectural specifications point to certain strengths: 10 physical cores provide raw parallel capacity, the 135.2 GB/s memory bandwidth exceeds the AMD part by 45.6 GB/s, and the 35 watt TDP suggests lower power draw. The larger L2 cache at 12 MB per module may benefit workloads that fit within that cache tier. However, none of these specifications have been validated through recorded performance measurements.

For users prioritizing documented performance, the AMD Ryzen 5 PRO 8645HS is the only part with verified scores. Its 82nd percentile ranking places it ahead of the majority of CPUs in the database. The nearest rival data shows it within 0.6% of the Ryzen 7 8700F, Core i7-13700TE, Ryzen 9 8945HS, and Core i7-12700F, which contextualizes its performance against more expensive or higher-tier parts. For users prioritizing efficiency specifications, the Qualcomm chip presents a lower TDP and higher memory bandwidth, but the absence of benchmark data means those specifications remain unvalidated. The database can only state what it has measured, and it has measured nothing for the Snapdragon X1P-66-100.
