AMD Ryzen 5 PRO 8540U vs Qualcomm Snapdragon X1P-64-100 Comparison

Head-to-Head Benchmarks

The AMD Ryzen 5 PRO 8540U and the Qualcomm Snapdragon X1P-64-100 take very different paths to mobile computing performance. The database contains a full set of benchmark results for the AMD part, while the Qualcomm part currently has no recorded benchmark scores. This makes a direct numerical comparison impossible, but the available data still reveals a clear performance hierarchy based on the AMD processor's recorded results and its position in the global percentile rankings.

The AMD Ryzen 5 PRO 8540U delivers a Cinebench R23 multi-core score of 15,456 points and a single-core score of 2,182 points. In Cinebench R20, it records 6,491 multi-core and 916 single-core. The older R15 test shows 1,557 multi-core and 219 single-core. These scores place the chip at the 76th percentile among all CPUs in the database, with an average benchmark score of 23,709 across all recorded tests.

The Qualcomm Snapdragon X1P-64-100 carries a 50th percentile ranking among all CPUs, but its average benchmark score is recorded as zero because no individual test results exist in the database. Without any measured scores, the database cannot establish a head-to-head delta between the two processors. What can be stated is that the AMD part sits well above the midpoint of the database's CPU population, while the Qualcomm part sits exactly at the midpoint based on its percentile field, but with no empirical measurements to confirm that placement.

The AMD processor's nearest rivals in the database provide context for its performance tier. The Intel Core i5-11500 scores an average of 23,718, which is essentially identical to the AMD chip's 23,709 average (a 0% delta). The Intel Xeon 6333P averages 23,823, putting it 0.5% ahead of the AMD part. The Intel Core 3 100HL averages 23,545, which is 0.7% behind. The AMD Ryzen 7 8840U averages 23,982, landing 1.1% ahead. These deltas are all small, indicating that the Ryzen 5 PRO 8540U sits in a tightly contested performance band. The Qualcomm chip has no nearest rivals listed, so it cannot be placed relative to any other processor in the database.

Where Each One Wins

The AMD Ryzen 5 PRO 8540U wins in every workload category where data exists, simply because it is the only one of the two with recorded scores. Its PassMark results show a strong all-round profile: 56,738 in integer math, 34,865 in floating point math, 18,218 in multithread, and 3,563 in single-thread. Data compression scores 205,703, data encryption scores 12,319, extended instructions score 15,410, and random string sorting scores 24,797. Physics tests record 983, and prime number finding records 66. These numbers indicate a processor that handles both integer-heavy and floating-point-heavy workloads competently, with particularly strong throughput in compression and encryption tasks.

The Qualcomm Snapdragon X1P-64-100 has no wins in any category because no benchmark results are recorded. Its architecture suggests certain strengths, but the database cannot confirm them with measurements. The chip uses 10 cores with 10 threads, a base clock of 3.40 GHz, and a 35 W TDP. It supports LPDDR5X memory with a dual-channel bus and 135.2 GB/s of bandwidth, which is notably higher than the AMD part's 89.6 GB/s. That memory bandwidth advantage could theoretically benefit memory-bound workloads, but without scores, it remains theoretical.

For users looking at the recorded data, the AMD chip is the only one with proven performance. The Qualcomm part is an unmeasured quantity in this database. The AMD processor's 76th percentile ranking means it outperforms roughly three-quarters of all CPUs tracked, a solid mid-to-upper tier position. The Qualcomm chip's 50th percentile ranking, if accurate, would place it at the median, but the absence of any test scores makes that ranking unverifiable.

Architecture Differences

The two processors diverge sharply in their internal designs. The AMD Ryzen 5 PRO 8540U is built on Zen 4 architecture with the Hawk Point codename, part of the 8000 series. It uses a 4 nm process from TSMC, with 20,900 million transistors on a 137 mm² die. It has 6 cores and 12 threads, enabled by simultaneous multithreading. Base clock is 3.20 GHz and boost clock reaches 4.90 GHz. The TDP is rated at 28 W. It uses the AMD Socket FP7.

The Qualcomm Snapdragon X1P-64-100 uses the Oryon codename under the Snapdragon X (Plus) generation. It also uses a 4 nm process from TSMC, but the database lists no transistor count or die size. It has 10 cores and 10 threads, meaning no simultaneous multithreading. Base clock is 3.40 GHz, with no boost clock recorded. TDP is rated higher at 35 W. It uses the Qualcomm BGA 2073 socket.

Cache layouts differ substantially. The AMD chip allocates 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Qualcomm chip uses 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3 cache. The AMD part's larger shared L3 pool could benefit workloads that repeatedly access a working set of data, while the Qualcomm part's larger per-core L1 and per-module L2 might help with more localized data access patterns.

Memory support also separates the two. The AMD processor supports DDR5 memory on a dual-channel bus, with 89.6 GB/s of bandwidth and ECC support enabled. The Qualcomm processor supports LPDDR5X memory on a dual-channel bus, with 135.2 GB/s of bandwidth and no ECC support. The Qualcomm chip's memory bandwidth advantage is substantial, 45.6 GB/s higher than the AMD part, which could matter for workloads that stream large amounts of data.

PCIe connectivity is similar in generation but differs in lane count. The AMD chip provides Gen 4 with 14 lanes from the CPU, while the Qualcomm chip provides Gen 4 with 12 lanes. Integrated graphics also differ: the AMD chip uses the Radeon 740M, while the Qualcomm chip uses the Adreno X1-85. Both are mobile processors with active production status. The AMD chip released on April 15, 2024, and the Qualcomm chip released on April 23, 2024, a separation of eight days.

Q: Does either processor support ECC memory?

The AMD Ryzen 5 PRO 8540U supports ECC memory. The Qualcomm Snapdragon X1P-64-100 does not support ECC memory.

Q: What is the TDP of each chip?

The AMD Ryzen 5 PRO 8540U has a TDP of 28 W. The Qualcomm Snapdragon X1P-64-100 has a TDP of 35 W, which is 7 W higher.

Q: Which processor has a higher percentile ranking in the database?

The AMD Ryzen 5 PRO 8540U ranks at the 76th percentile among all CPUs. The Qualcomm Snapdragon X1P-64-100 ranks at the 50th percentile. However, the Qualcomm chip has no recorded benchmark scores, so its percentile is not backed by measurements.

The Verdict

The database presents a lopsided comparison. The AMD Ryzen 5 PRO 8540U has a full set of benchmark results across Cinebench R15, R20, R23, and multiple PassMark tests. These scores place it at the 76th percentile, with an average benchmark score of 23,709. Its nearest rivals all cluster within 1.1% of its average score, confirming that it performs in line with established mid-range desktop and mobile processors like the Intel Core i5-11500 and the AMD Ryzen 7 8840U.

The Qualcomm Snapdragon X1P-64-100 has no recorded benchmark scores. Its 50th percentile ranking and zero average benchmark score mean the database cannot confirm any level of performance. The chip's specifications show 10 cores, 10 threads, a 3.40 GHz base clock, 35 W TDP, and 135.2 GB/s memory bandwidth, but none of these specifications translate into measured results.

For anyone relying on the database, the AMD Ryzen 5 PRO 8540U is the only processor with verified performance data. Its multi-core Cinebench R23 score of 15,456 and single-core score of 2,182 represent concrete, reproducible measurements. The Qualcomm chip remains an unverified entry, with architectural promise but no empirical evidence in the records.

The choice is therefore straightforward based on available data. The AMD processor delivers proven performance across a wide range of workloads, sits at the 76th percentile, and has nearest rivals that validate its positioning. The Qualcomm processor offers higher memory bandwidth and more cores, but the absence of any benchmark results means its actual performance cannot be assessed. The data supports selecting the AMD Ryzen 5 PRO 8540U for any application where measured performance is required. The Qualcomm Snapdragon X1P-64-100 would only be a consideration if its specifications alone, particularly the 135.2 GB/s memory bandwidth and 10-core layout, were deemed sufficient without test scores. The database, as it stands, provides no evidence that the Qualcomm chip outperforms the AMD chip in any workload.
