AMD Ryzen 5 PRO 8540U vs Qualcomm Snapdragon X1E-78-100 Comparison

AMD Ryzen 5 PRO 8540U vs Qualcomm Snapdragon X1E-78-100

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen 5 PRO 8540U and the Qualcomm Snapdragon X1E-78-100. For the AMD processor, a full suite of 17 benchmark scores is recorded across Cinebench and Passmark tests. For the Qualcomm Snapdragon X1E-78-100, no benchmark scores are recorded in the database, resulting in an average benchmark score of zero and a wins count of zero for both processors in direct comparisons.

The AMD Ryzen 5 PRO 8540U produces a multi-threaded Cinebench R23 score of 15456 and a single-core score of 2182. In Cinebench R20, it scores 6491 multi-core and 916 single-core, while in Cinebench R15 it reaches 1557 multi-core and 219 single-core. These results indicate a processor that scales well from single-threaded workloads to heavily threaded tasks, with the multi-core score roughly seven times the single-core score in R23.

Passmark results for the AMD chip show strong integer math performance at 56738, floating point math at 34865, and extended instructions at 15410. Data compression reaches 205703, while data encryption hits 12319. The processor achieves a multi-thread score of 18218 and a single-thread score of 3563. Random string sorting scores 24797, physics processing scores 983, and find prime numbers scores 66.

The absence of benchmark data for the Qualcomm Snapdragon X1E-78-100 means the database cannot establish a direct performance delta between the two mobile processors. The AMD part holds a recorded percentile rank of 76 among all CPUs, while the Qualcomm part sits at percentile 50, though that figure reflects the lack of recorded measurements rather than a tested performance level. The nearest rivals to the AMD processor in the database include the Intel Core i5-11500 with an average score of 23718 and a delta of 0 percent, the Intel Xeon 6333P at 23823 with a delta of -0.5 percent, the Intel Core 3 100HL at 23545 with a delta of 0.7 percent, and the AMD Ryzen 7 8840U at 23982 with a delta of -1.1 percent. These comparisons place the Ryzen 5 PRO 8540U within a tight performance cluster, within roughly one percent of each listed rival.

The Verdict

The data favors the AMD Ryzen 5 PRO 8540U for any user who relies on measurable benchmark results, simply because it is the only one of the two with recorded scores. The Qualcomm Snapdragon X1E-78-100 has no benchmark entries, so any performance conclusion about it would lack the support of the database. The AMD processor delivers a Cinebench R23 multi-core score of 15456 and a Passmark single-thread score of 3563, which places it in the 76th percentile of all CPUs. The Qualcomm part is listed in the 50th percentile, but that rank corresponds to an average benchmark score of zero, so it does not represent tested capability.

The AMD chip offers 6 cores and 12 threads, while the Qualcomm chip offers 12 cores and 12 threads. Core count alone does not determine performance, and with no benchmark data for the Qualcomm part, the database cannot confirm whether its additional cores translate into higher throughput. The Ryzen 5 PRO 8540U shows consistent scores across both Cinebench and Passmark suites, indicating a balanced design for single-threaded responsiveness and multi-threaded workloads. The processor also records a data compression score of 205703 and an integer math score of 56738, both strong figures for productivity-oriented mobile computing.

For users selecting strictly from the recorded data, the AMD Ryzen 5 PRO 8540U is the only option with verified results. The Qualcomm Snapdragon X1E-78-100 remains a processor without measurable output in this database, so no performance verdict can be assigned to it. The AMD part also carries a higher percentile ranking, a full suite of benchmark scores, and a lower thermal design point of 28 watts compared to the Qualcomm part's 35 watts, which suggests potentially better efficiency for mobile chassis designs.

Architecture Differences

The AMD Ryzen 5 PRO 8540U uses the Zen 4 architecture under the codename Hawk Point, belonging to the 8000 series and the Ryzen 5 generation.

Where Each One Wins

The AMD Ryzen 5 PRO 8540U wins in any workload where recorded benchmark data matters, because it is the only processor in this comparison with scores in the database. Its Cinebench R23 multi-core score of 15456 and single-core score of 2182 indicate strong performance across both parallel and single-threaded tasks. Passmark results support this, with a multi-thread score of 18218 and a single-thread score of 3563. The AMD part also wins on thermal design, with a 28 watt TDP compared to the Qualcomm part's 35 watts, which favors thinner mobile designs with limited cooling capacity.

The AMD processor wins on ECC memory support, a feature absent from the Qualcomm chip, and on PCIe lane count, with 14 lanes versus 12 lanes. Its L3 cache of 16 MB shared exceeds the Qualcomm part's 6 MB shared L3 cache. The AMD chip also has a recorded boost clock of 4.90 GHz, while the Qualcomm part has no boost clock listed. The AMD processor's percentile rank of 76 versus the Qualcomm part's 50 further reinforces its standing in the database, though that Qualcomm rank reflects missing data.

The Qualcomm Snapdragon X1E-78-100 wins on core count with 12 cores versus 6, and on memory bandwidth with 135.2 GB/s versus 89.6 GB/s. Its LPDDR5X memory support is a different memory type than the AMD part's DDR5, and its L1 cache of 288 KB per core and L2 cache of 12 MB per module are larger per unit than the AMD part's 64 KB and 1 MB figures. The Qualcomm chip also has a higher base clock of 3.40 GHz versus 3.20 GHz. These specification advantages lack benchmark verification, so the database cannot confirm whether they produce real-world performance gains. The Qualcomm processor's integrated Adreno X1-85 graphics and the AMD processor's Radeon 740M are both recorded, but no graphics benchmarks exist for either chip.
