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

The AMD Ryzen 5 PRO 8640U and Qualcomm Snapdragon X1E-80-100 are both active mobile processors built on TSMC's 4 nm node. The Ryzen has a full benchmark record and an 81st percentile ranking, while the Snapdragon has no recorded benchmark scores and sits at the 50th percentile with an average score of 0.

Head-to-Head Benchmarks

The head-to-head table for this pair is empty. No shared test runs are recorded, and neither processor has a direct win against the other. The comparison therefore relies on the Ryzen's standalone results and on the Snapdragon's absent benchmark list.

The Ryzen 5 PRO 8640U delivers a Cinebench R23 multicore score of 19982 and a single-core score of 2821. In Cinebench R20 it scores 8392 multicore and 1184 single-core. In Cinebench R15 it scores 2014 multicore and 284 single-core. Passmark results include a multithread score of 22795, a single-thread score of 3732, integer math at 74875, floating point math at 45265, data compression at 260925, data encryption at 15843, extended instructions at 19130, physics at 1154, random string sorting at 32114, and find prime numbers at 78.

The Snapdragon X1E-80-100 has no recorded Cinebench or Passmark score. Its average benchmark score is 0, and its percentile against all CPUs is 50. No direct performance delta can be computed between the two processors.

For context, the Ryzen's average benchmark score of 30254 places it near a tight group of rivals. It is 0.1% above the AMD Ryzen 7 2700X, which averages 30213. It is 0.4% below the AMD Ryzen 7 7736U (30364) and the AMD Ryzen 5 7640HS (30390), and 0.6% below the Intel Core i9-11980HK (30422). The rival average scores range from 30213 to 30422, so the Ryzen sits in a narrow band around those parts.

Architecture Differences

Both processors use TSMC's 4 nm process, but their internal designs diverge. The Ryzen uses Zen 4 under the Hawk Point codename and is listed in the Ryzen 5 generation. The Snapdragon uses the Oryon codename and is listed in the Snapdragon X (Elite) generation, but the database does not record an architecture name for it.

The Ryzen has 6 cores and 12 threads, so each core supports two threads. The Snapdragon has 12 cores and 12 threads, so its thread count equals its core count. Core counts differ, but thread counts are the same.

Cache layouts differ substantially. The Ryzen has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Snapdragon has 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3. The Ryzen's L3 is larger, while the Snapdragon's L1 and L2 allocations are larger, with the L2 organized per module rather than per core.

Memory support also differs. The Ryzen uses DDR5 on a dual-channel bus with 89.6 GB/s of bandwidth and supports ECC. The Snapdragon uses LPDDR5X on a dual-channel bus with 135.2 GB/s of bandwidth and does not support ECC. The Snapdragon's recorded memory bandwidth is higher.

PCIe connectivity differs: the Ryzen has Gen 4 with 20 lanes, while the Snapdragon has Gen 4 with 12 lanes. The integrated GPUs are the Radeon 760M on the Ryzen and the Adreno X1-85 on the Snapdragon. The Ryzen uses AMD Socket FP7, while the Snapdragon uses Qualcomm BGA 2073. The Ryzen's TDP is 28, and the Snapdragon's TDP is 35.

Clock speeds differ as well. The Ryzen has a base clock of 3.50 and a boost clock of 4.90. The Snapdragon has a base clock of 3.40 and a boost clock of 4.00. Both processors are listed as active mobile parts with locked multipliers, and neither has a recorded 3D V-Cache.

The Ryzen lists 25,000 million transistors and a 178 mm² die. The Snapdragon has no recorded transistor count or die size. The Ryzen's part numbers are 100-000001318 (FP7r2) and 100-000001378 (FP7), while the Snapdragon's part number is X1E80100. Release dates are also close: the Ryzen is dated 2024-04-15, and the Snapdragon is dated 2024-04-23.

Where Each One Wins

Because the head-to-head table is empty, the database records no direct wins for the Ryzen and no direct wins for the Snapdragon. In standalone benchmarks, however, the Ryzen posts measurable results in every workload it was tested on. Its Cinebench R23 multicore score is 19982, its Passmark multithread score is 22795, and its single-thread score is 3732. These are the only benchmark wins available for this comparison.

The Snapdragon cannot be assigned a benchmark win in any workload, because no benchmark scores are recorded. Its specification sheet does show differences: 12 cores versus 6, 135.2 GB/s memory bandwidth versus 89.6 GB/s, and a 35 TDP versus 28. Those are not measured wins, and the database does not translate them into benchmark performance.

For workloads covered by Cinebench and Passmark, the Ryzen is the only part with recorded data. The Snapdragon's higher memory bandwidth and larger core count remain specification advantages, but no benchmark result confirms them.

The Verdict

Strictly from the recorded data, the AMD Ryzen 5 PRO 8640U is the only part in this pairing with measurable performance. It has an average benchmark score of 30254, an 81st percentile ranking, and a complete set of Cinebench and Passmark results. The Qualcomm Snapdragon X1E-80-100 has an average score of 0, a 50th percentile ranking, and no recorded benchmark runs.

The data points to the Ryzen for the workloads covered by Cinebench and Passmark. The Snapdragon's 12 cores, 135.2 GB/s memory bandwidth, and 35 TDP are specification differences, but the database provides no benchmark evidence that they translate into a win in any test.
