AMD Ryzen 5 PRO 8640HS vs Qualcomm Snapdragon X1E-84-100 Comparison

Head-to-Head Benchmarks

The database contains a complete benchmark profile for the AMD Ryzen 5 PRO 8640HS, while the Qualcomm Snapdragon X1E-84-100 has no recorded benchmark scores. This asymmetry makes a direct score-for-score comparison impossible. The recorded data for the AMD part, however, places it firmly in the upper half of all CPUs, with a percentile rank of 80. Its average benchmark score of 28,478 sits just 0.2% below the Intel Xeon E-2436 (28,530) and 0.2% below the AMD Ryzen 7 PRO 6850HS (28,549). It is 0.3% behind the Intel Core 5 220H (28,574) and 0.3% ahead of the AMD Ryzen 7 PRO 6850U (28,379).

The AMD part shows its strongest absolute numbers in the Cinebench suite. The multi-core R23 score of 18,104 dwarfs the single-core R23 result of 2,555, indicating strong scaling across the six cores and twelve threads. The R20 multi-core score of 7,603 and the R15 multi-core score of 1,824 follow the same pattern. Single-core performance in R15 reaches 257, while R20 single-core lands at 1,073.

PassMark results add further detail. The data compression score of 246,446 is the largest single value in the entire benchmark set. Integer math scores 69,839, floating point math scores 43,019, and extended instructions score 18,507. Random string sorting delivers 30,235. Data encryption reaches 14,962. The find prime numbers test produces a score of 71, which is the lowest recorded value. The multithread score of 21,465 and the single-thread score of 3,561 complete the PassMark profile. The physics test yields 1,043.

For the Snapdragon X1E-84-100, the database lists no benchmark entries, no average score, and no nearest rivals. Its percentile rank of 50 is the only comparative datum available, and that value reflects a default position rather than a measured performance tier. Any head-to-head statement must therefore rest on the AMD part's measured results alone, with the Qualcomm part serving only as a structural comparison based on specifications.

Where Each One Wins

The AMD Ryzen 5 PRO 8640HS wins in measured performance, since it is the only one of the two with recorded benchmark results. The data shows an 80th percentile ranking among all CPUs, with a multi-core R23 score of 18,104 and a single-core R23 score of 2,555. Its PassMark single-thread score of 3,561 and multithread score of 21,465 give it a complete performance profile. The nearest rival comparisons show it trading fractions of a percent with four other processors, all within 0.3% of its average score, which indicates the AMD part sits in a tightly packed performance cluster.

The Qualcomm Snapdragon X1E-84-100 wins in raw specification counts. Its 12 cores double the AMD part's six cores. Its base clock of 3.80 GHz is higher, and its memory bandwidth of 135.2 GB/s exceeds the AMD part's 89.6 GB/s by a wide margin. The LPDDR5X memory support offers a different memory ecosystem than the AMD part's DDR5. The Snapdragon also carries a larger L1 cache per core at 288 KB and a larger L2 cache per module at 12 MB, compared to the AMD part's 64 KB L1 per core and 1 MB L2 per core.

The specification advantage for the Snapdragon does not translate into measured wins in the database, because no benchmark scores exist for it. The AMD part's wins are all empirical, while the Snapdragon's wins are all theoretical. A system builder choosing between the two would need to weigh the AMD part's verified scores against the Snapdragon's unverified core and bandwidth advantages.

Specification Differences

The two processors differ across nearly every major specification field. The AMD Ryzen 5 PRO 8640HS has 6 cores and 12 threads; the Qualcomm Snapdragon X1E-84-100 has 12 cores and 12 threads. The AMD base clock is 3.50 GHz with a boost of 4.90 GHz; the Snapdragon base clock is 3.80 GHz with a boost of 4.20 GHz. The AMD TDP is 28 watts; the Snapdragon TDP is 35 watts.

The AMD part uses AMD Socket FP7; the Snapdragon uses Qualcomm BGA 2073. The AMD part belongs to the 8000 series, while the Snapdragon has no series designation. The AMD codename is Hawk Point; the Snapdragon codename is Oryon. The AMD generation is listed as Ryzen 5 (Zen 4 (Hawk Point)); the Snapdragon generation is Snapdragon X (Elite). The AMD architecture is Zen 4; the Snapdragon architecture field is null.

Both parts use a 4 nm process from TSMC. The AMD die size is 178 mm² with 25,000 million transistors; the Snapdragon die size and transistor count are not recorded. The L1 cache differs: 64 KB per core for AMD versus 288 KB per core for Qualcomm. The L2 cache differs: 1 MB per core for AMD versus 12 MB per module for Qualcomm. The L3 cache differs: 16 MB shared for AMD versus 6 MB shared for Qualcomm.

Memory support differs: DDR5 for AMD versus LPDDR5X for Qualcomm. Both are dual-channel, but the bandwidth differs at 89.6 GB/s versus 135.2 GB/s. ECC memory is supported on the AMD part only. PCIe lanes differ: Gen 4 with 20 lanes for AMD versus Gen 4 with 12 lanes for Qualcomm. The integrated graphics differ: Radeon 760M for AMD versus Adreno X1-85 for Qualcomm. The release dates are close, with the AMD part on 2024-04-15 and the Snapdragon on 2024-04-23. Both are active in production, both have locked multipliers, and neither has a recorded launch MSRP.

Architecture Differences

The AMD Ryzen 5 PRO 8640HS uses the Zen 4 architecture under the Hawk Point codename. It is built on a 4 nm TSMC process with 25,000 million transistors on a 178 mm² die. The core layout puts 6 cores and 12 threads into a design with 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The memory controller uses DDR5 with a dual-channel bus and 89.6 GB/s of bandwidth, and ECC is enabled. The PCIe interface runs Gen 4 across 20 CPU lanes. The integrated graphics block is the Radeon 760M.

The Qualcomm Snapdragon X1E-84-100 uses the Oryon codename under the Snapdragon X (Elite) generation. The architecture field is not recorded in the database. It is also built on a 4 nm TSMC process, but the transistor count and die size are not listed. The core layout puts 12 cores and 12 threads, meaning each core maps to a single thread with no simultaneous multithreading. The cache hierarchy uses 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3. The memory controller uses LPDDR5X with a dual-channel bus and 135.2 GB/s of bandwidth, and ECC is not supported. The PCIe interface runs Gen 4 across 12 CPU lanes. The integrated graphics block is the Adreno X1-85.

The architectural contrast is sharp. AMD pairs a smaller core count with simultaneous multithreading, a larger L3 pool, and ECC support. Qualcomm pairs a larger core count with a thread-per-core model, a much larger L1 and L2 allocation, and a higher memory bandwidth ceiling. The process node is identical at 4 nm from TSMC, which puts the performance difference on the core designs themselves rather than on the manufacturing process. The AMD part's Zen 4 cores have a higher boost clock, while the Snapdragon's Oryon cores have a higher base clock and more physical cores. The cache strategy also diverges: AMD concentrates shared L3 cache, while Qualcomm puts more cache closer to the cores. The database contains no benchmark results for the Snapdragon, so the architectural differences cannot be validated against measured performance. The AMD part's recorded scores confirm its Zen 4 design delivers competitive results in the 80th percentile of all CPUs.
