AMD Ryzen 5 PRO 8640HS vs Qualcomm Snapdragon X1E-80-100 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between these two mobile processors, though direct head-to-head benchmark comparisons are limited. The AMD Ryzen 5 PRO 8640HS has a full suite of 17 benchmark results across Cinebench and Passmark tests, while the Qualcomm Snapdragon X1E-80-100 has no recorded benchmark scores in the database. This absence of data for the Snapdragon makes quantitative comparison impossible for most workloads.

The AMD processor delivers a Cinebench R23 multi-core score of 18104, a result that places it in the 80th percentile among all CPUs in the database. Its single-core R23 score of 2555 further confirms strong per-thread performance. In Cinebench R20, the chip scores 7603 multi-core and 1073 single-core, while the older R15 test yields 1824 multi-core and 257 single-core.

Passmark results for the AMD part are extensive. The multi-thread score of 21465, single-thread score of 3561, and integer math score of 69839 indicate robust general-purpose compute. Floating point math reaches 43019, extended instructions score 18507, and data encryption hits 14962. Data compression reaches 246446, while random string sorting scores 30235. Physics simulation scores 1043, and the find prime numbers test produces 71.

The average benchmark score for the AMD chip is 28478, placing it among competitive mobile processors. Its nearest rivals in the database include the Intel Xeon E-2436 with an average score of 28530, a delta of -0.2 percent, and the AMD Ryzen 7 PRO 6850HS at 28549, also -0.2 percent. The Intel Core 5 220H scores 28574, a -0.3 percent delta, while the AMD Ryzen 7 PRO 6850U trails with 28379, a 0.3 percent delta. These margins are remarkably tight, with all four rivals within 0.3 percent of the Ryzen 5 PRO 8640HS.

The Snapdragon X1E-80-100 holds a 50th percentile ranking among all CPUs, but with an average benchmark score of zero and no recorded tests, this ranking appears provisional. The database contains no head-to-head benchmark entries between the two processors, and the Snapdragon has no nearest rival data. As a result, the only measurable comparisons come from the AMD side of the ledger.

Architecture Differences

The two chips diverge sharply in architectural design. The AMD Ryzen 5 PRO 8640HS uses the Zen 4 architecture under the Hawk Point codename, belonging to the 8000 series and the Ryzen 5 generation. It packs 6 cores and 12 threads, with a base clock of 3.50 GHz and a boost clock of 4.90 GHz. Thermal design power is 28 watts, and it fits the AMD Socket FP7.

The Qualcomm Snapdragon X1E-80-100 uses the Oryon codename, part of the Snapdragon X Elite generation. It provides 12 cores and 12 threads, indicating no simultaneous multithreading. Base clock runs at 3.40 GHz with a boost of 4.00 GHz, both lower than the AMD part. TDP is higher at 35 watts, and the socket is Qualcomm BGA 2073.

Both processors are built on a 4 nm process at TSMC, so the manufacturing node is identical. The AMD chip integrates 25,000 million transistors on a 178 mm² die. Transistor count and die size for the Snapdragon are not recorded in the database.

Cache configurations differ substantially. The AMD chip offers 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Snapdragon provides 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3. The AMD chip has a larger total L3 pool, while the Snapdragon allocates more L2 per module and considerably more L1 per core.

Memory support also separates the two. The AMD processor uses DDR5 memory on a dual-channel bus with 89.6 GB/s of bandwidth and supports ECC memory. The Snapdragon uses LPDDR5X on a dual-channel bus with higher bandwidth at 135.2 GB/s but no ECC support. PCIe connectivity favors AMD with Gen 4 and 20 lanes from the CPU, while the Snapdragon offers Gen 4 with 12 lanes.

Integrated graphics differ as well. The AMD part carries the Radeon 760M, while the Snapdragon includes the Adreno X1-85. Both target the mobile market segment and remain in active production. The AMD chip released on 2024-04-15, and the Snapdragon followed on 2024-04-23. Neither processor has a recorded launch MSRP in the database, and neither has an unlocked multiplier.

The AMD chip lists two part numbers, 100-000001354 for FP7r2 and 100-000001382 for FP7. The Snapdragon uses a single part number, X1E80100.

Where Each One Wins

The AMD Ryzen 5 PRO 8640HS wins in every measurable category simply because it has recorded data and the Snapdragon X1E-80-100 does not. For multi-threaded productivity workloads, the AMD chip shows strong results with an R23 multi-core score of 18104 and a Passmark multi-thread score of 21465. The 12 threads of the AMD part, despite fewer physical cores, allow it to handle heavily parallel tasks such as video encoding, 3D rendering, and scientific computation.

Single-thread performance on the AMD chip is equally solid. The R23 single-core score of 2555 and Passmark single-thread score of 3561 indicate responsive application behavior for everyday tasks, office work, and lightly threaded software. The higher boost clock of 4.90 GHz on the AMD part supports this advantage.

The Snapdragon, with its 12 cores and 12 threads, theoretically offers parallel compute headroom, but the absence of benchmark data means the database cannot confirm any advantage. Its higher memory bandwidth of 135.2 GB/s compared to 89.6 GB/s for the AMD chip suggests potential strengths in memory-intensive workloads, but no scores validate this. The larger L1 cache of 288 KB per core and 12 MB L2 per module could benefit certain access patterns, yet again, no recorded measurements back this up.

For general productivity, the AMD chip's higher boost clock and mature x86 ecosystem position it favorably. The Snapdragon's 4.00 GHz boost clock is notably lower, which may limit peak single-thread performance, but its 12 physical cores could provide sustained multi-core throughput if software scales well. The database simply lacks the evidence to confirm either scenario for the Snapdragon.

The AMD processor also holds an advantage in its 80th percentile ranking versus the Snapdragon's 50th percentile. The percentile field reflects where each chip stands relative to all CPUs in the database, and the AMD part sits well above the midpoint. The Snapdragon's ranking at the 50th percentile, combined with zero average benchmark score, suggests an incomplete or unverified entry.

The Verdict

The data supports a clear conclusion for anyone choosing between these two mobile processors. The AMD Ryzen 5 PRO 8640HS delivers verified, comprehensive performance across every benchmark category in the database. Its Cinebench R23 multi-core score of 18104, single-core score of 2555, and average benchmark score of 28478 place it in the 80th percentile of all CPUs. Its nearest rivals, including the Intel Xeon E-2436 and AMD Ryzen 7 PRO 6850HS, sit within 0.3 percent of its average score, confirming that it competes at a high level among established mobile processors.

The Snapdragon X1E-80-100 cannot be evaluated on performance grounds because the database contains no benchmark results for it. Its 50th percentile ranking and zero average score indicate that no verified measurements exist. The chip does offer architectural advantages on paper, including 12 physical cores, 135.2 GB/s of memory bandwidth, and a larger L1 cache per core, but these specifications do not translate into confirmed performance without recorded tests.

For users who require proven multi-threaded and single-threaded performance, the AMD Ryzen 5 PRO 8640HS is the only option with data to support it. The 28 watt TDP also suggests efficient operation for mobile use. The Snapdragon's 35 watt TDP, higher memory bandwidth, and 12-core layout may appeal to those prioritizing raw core count or memory throughput, but the database provides no evidence that these translate into real-world wins.

The AMD chip also benefits from ECC memory support, 20 PCIe Gen 4 lanes, and a mature Zen 4 architecture with a 4.90 GHz boost clock. The Snapdragon counters with LPDDR5X memory support, 12 MB of L2 per module, and a 4 nm TSMC process, but these features remain unquantified in terms of actual performance.

Given the available data, the AMD Ryzen 5 PRO 8640HS is the defensible choice. The Snapdragon X1E-80-100 may hold potential, but until benchmark results are recorded, its capabilities cannot be assessed. The 80th percentile ranking for AMD stands in contrast to the 50th percentile for Qualcomm, and the average benchmark score of 28478 versus zero leaves no ambiguity in the recorded measurements.
