Architecture Differences

The AMD Ryzen 5 PRO 8640U and Qualcomm Snapdragon X1E-84-100 represent fundamentally different design philosophies despite sharing the same 4 nm TSMC process node. AMD's chip uses the Zen 4 architecture under the Hawk Point codename, belonging to the 8000 series. Qualcomm's part uses the Oryon codename under the Snapdragon X (Elite) generation. Both are active mobile processors released within days of each other, with AMD launching on April 15, 2024, and Qualcomm on April 23, 2024.

The core configurations differ sharply. AMD provides 6 cores and 12 threads, enabling simultaneous multithreading to extract more work from each physical core. Qualcomm provides 12 physical cores but only 12 threads, meaning no multithreading per core. This gives Qualcomm a raw core count advantage, but AMD relies on thread duplication to improve throughput in multithreaded workloads.

Cache hierarchies are organized differently. AMD allocates 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. Qualcomm allocates 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3 cache. The Qualcomm L1 allocation is substantially larger per core, while AMD's L3 cache is larger overall. AMD's transistor count stands at 25,000 million on a 178 mm² die, while Qualcomm's transistor count and die size are not recorded in the database.

Memory support diverges as well. AMD uses DDR5 with dual-channel access and 89.6 GB/s of bandwidth, plus ECC support. Qualcomm uses LPDDR5X with dual-channel access and a higher 135.2 GB/s bandwidth, but no ECC. PCIe connectivity also differs, with AMD offering Gen 4 with 20 lanes (CPU only) versus Qualcomm's Gen 4 with 12 lanes (CPU only). Both integrate graphics, with AMD using the Radeon 760M and Qualcomm using the Adreno X1-85. AMD's socket is FP7 (with part numbers for both FP7r2 and FP7 variants), while Qualcomm uses BGA 2073. Neither processor has an unlocked multiplier, and neither has a recorded launch MSRP.

Head-to-Head Benchmarks

The head-to-head benchmark data between these two processors is empty in the database, meaning no direct comparative test results exist for this specific pairing. However, the AMD Ryzen 5 PRO 8640U has a full suite of individual benchmark scores across multiple test families, while the Qualcomm Snapdragon X1E-84-100 has no recorded benchmark scores at all.

The AMD processor's Cinebench results show strong multithreaded performance. It scores 2014 in Cinebench R15 multicore and 284 in single-core. In Cinebench R20, it scores 8392 multicore and 1184 single-core. Cinebench R23 results are 19982 multicore and 2821 single-core. These figures indicate a balanced capability across rendering workloads, with the single-core scores representing roughly 14% of the multicore totals in each version.

PassMark results for the AMD chip span multiple specialized tests. Data compression scores 260925, data encryption scores 15843, and extended instructions score 19130. Finding prime numbers yields a score of 78, while floating point math scores 45265 and integer math scores 74875. The multithread score is 22795, physics scores 1154, and random string sorting scores 32114. Single-thread performance is recorded at 3732 in both the "single_thread" and "singlethread" test fields.

Because the Qualcomm part has zero benchmark entries, the database cannot show any comparative wins or losses. The wins counters for both processors in the head-to-head section are zero. The average benchmark score for Qualcomm is listed as 0, which places it at the 50th percentile solely due to the lack of data rather than measured performance. In contrast, AMD's average benchmark score of 30254 places it at the 81st percentile.

The Verdict

The recorded data supports a clear choice for users who need verified performance numbers: the AMD Ryzen 5 PRO 8640U is the only processor in this comparison with any benchmark results. Its 81st percentile standing among all CPUs indicates it delivers above-average performance in the database's measurements. The Qualcomm Snapdragon X1E-84-100, despite having 12 cores and a higher memory bandwidth, offers no recorded benchmark scores to evaluate its real-world performance.

The AMD chip's nearest rivals in the database include the AMD Ryzen 7 2700X with an average score of 30213 and a delta of 0.1%, the AMD Ryzen 7 7736U at 30364 with a delta of -0.4%, the AMD Ryzen 5 7640HS at 30390 with a delta of -0.4%, and the Intel Core i9-11980HK at 30422 with a delta of -0.6%. These tight deltas, all within 0.6 percentage points, show that the Ryzen 5 PRO 8640U sits in a competitive performance band around the 30000 average score mark.

For users who prioritize verified results and a known performance position, the AMD processor is the only one with data to support a decision. The Qualcomm chip's absence of benchmark data means it cannot be recommended based on measured performance, only on its listed specifications. Those specifications include a higher core count and greater memory bandwidth, but without test scores, the practical impact of those features remains unquantified.

Specification Differences

The two processors differ across nearly every major specification category recorded in the database. Clock speeds show a split: AMD has a 3.50 GHz base and 4.90 GHz boost, while Qualcomm has a 3.80 GHz base and 4.20 GHz boost. AMD leads in boost, Qualcomm leads in base. Thermal design power differs, with AMD at 28 watts and Qualcomm at 35 watts. The AMD socket is FP7, while Qualcomm uses BGA 2073.

Architecture and generation labels are distinct. AMD uses Zen 4 with the Hawk Point codename under the "Ryzen 5 (Zen 4 (Hawk Point))" generation. Qualcomm's architecture field is empty, with the Oryon codename under the "Snapdragon X (Elite)" generation. AMD's process node is 4 nm at TSMC with 25,000 million transistors and a 178 mm² die size. Qualcomm also uses 4 nm at TSMC, but its transistor count and die size are not recorded.

Cache configurations differ in every level. AMD has 64 KB L1 per core, 1 MB L2 per core, and 16 MB L3 shared. Qualcomm has 288 KB L1 per core, 12 MB L2 per module, and 6 MB L3 shared. Memory support differs by type, with AMD on DDR5 and Qualcomm on LPDDR5X, though both use dual-channel buses. Bandwidth favors Qualcomm at 135.2 GB/s versus AMD's 89.6 GB/s. ECC support exists only on AMD. PCIe lanes favor AMD with 20 Gen 4 lanes versus Qualcomm's 12 Gen 4 lanes. Integrated graphics differ, with AMD's Radeon 760M versus Qualcomm's Adreno X1-85. AMD's part number is listed as 100-000001318 (FP7r2) and 100-000001378 (FP7), while Qualcomm's is X1E84100. Both are active mobile parts with locked multipliers and no launch MSRP.

Where Each One Wins

Based strictly on recorded data, the AMD Ryzen 5 PRO 8640U wins every measurable category because it is the only processor with benchmark results. It demonstrates strong multithreaded rendering capability with a Cinebench R23 multicore score of 19982, which is particularly relevant for content creation workloads that scale across cores. Its Cinebench R23 single-core score of 2821 indicates solid responsiveness in lightly threaded tasks. PassMark results show particular strength in data compression at 260925, integer math at 74875, and floating point math at 45265, making it suitable for scientific calculations and data processing. The 81st percentile ranking confirms it outperforms the majority of CPUs in the database.

The Qualcomm Snapdragon X1E-84-100 wins on paper specifications that could translate to advantages in certain scenarios, though no benchmark data confirms this. Its 12 cores and 12 threads provide a larger physical core pool than AMD's 6 cores and 12 threads, which could benefit workloads that scale linearly with core count but do not benefit from simultaneous multithreading. Its memory bandwidth of 135.2 GB/s is 45.6 GB/s higher than AMD's 89.6 GB/s, which could improve performance in memory-bandwidth-sensitive tasks such as large data transfers or certain scientific simulations. The higher base clock of 3.80 GHz may provide better sustained performance in power-constrained scenarios. However, none of these theoretical advantages are verified by recorded scores, so the database cannot confirm any actual wins for the Qualcomm part.
