Q: Which processor uses a smaller manufacturing process?

A: Both processors are built on a 4 nm process node at TSMC. The AMD Ryzen 7 PRO 8840U has a die size of 178 mm² and 25,000 million transistors, while the die size and transistor count for the Qualcomm Snapdragon X1P-66-100 are not recorded in the database.

Architecture Differences

The AMD Ryzen 7 PRO 8840U is built on the Zen 4 architecture with the codename Hawk Point, part of the 8000 series. It is a Ryzen 7 generation processor. The Qualcomm Snapdragon X1P-66-100 uses the Oryon codename and belongs to the Snapdragon X (Plus) generation. The AMD chip has a known architecture designation, while the Qualcomm processor's architecture field is not recorded.

The manufacturing process is identical at 4 nm, with both chips produced by TSMC. However, the AMD processor has a recorded die size of 178 mm² and a transistor count of 25,000 million, whereas the Qualcomm chip's die size and transistor count are absent from the database.

Cache organization differs substantially. AMD uses a traditional per-core design: 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Qualcomm uses a hybrid layout: 288 KB L1 per core, 12 MB L2 per module, and 6 MB shared L3. The larger L1 and module-based L2 suggest a different approach to data locality, while the AMD chip's shared L3 is more than double the Qualcomm's.

Memory support also diverges. The AMD Ryzen 7 PRO 8840U supports DDR5 with dual-channel memory and 89.6 GB/s bandwidth. The Qualcomm Snapdragon X1P-66-100 supports LPDDR5X with dual-channel memory and 135.2 GB/s bandwidth. The Qualcomm chip also has ECC memory disabled, while the AMD chip supports ECC.

PCIe lanes differ: the AMD processor provides Gen 4 with 20 lanes (CPU only), while the Qualcomm provides Gen 4 with 12 lanes (CPU only). Integrated graphics also differ: AMD uses the Radeon 780M, while Qualcomm uses the Adreno X1-85.

The AMD chip uses AMD Socket FP7, while the Qualcomm uses Qualcomm BGA 2073. Both are active production parts with locked multipliers. The AMD part numbers are 100-000001317 (FP7r2) and 100-000001377 (FP7), while the Qualcomm part number is X1P66100.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the AMD Ryzen 7 PRO 8840U and the Qualcomm Snapdragon X1P-66-100. The Qualcomm chip has an empty benchmark list and an average benchmark score of zero, while the AMD chip has a full suite of scores.

The AMD Ryzen 7 PRO 8840U's average benchmark score is 32233, placing it at the 83rd percentile. Its nearest rivals include the Intel Core i9-11900 with an average score of 32226 (0% delta), the Intel Core i5-14400F at 32279 (-0.1% delta), the Intel Core i7-12800H at 32121 (0.3% delta), and the Intel Core i5-14400 at 32115 (0.4% delta). These comparisons show the AMD chip sits in a tight cluster around the 32200-32280 range.

In Cinebench tests, the AMD processor scores 2041 in R15 multicore and 288 in R15 single-core. In R20, it scores 8506 multicore and 1200 single-core. In R23, the multicore score is 20254 and single-core is 2859. These numbers indicate strong multi-threaded performance due to the 16 threads.

PassMark results for the AMD chip include multithread at 23850, single-thread at 3641, integer math at 88339, floating point math at 50746, data compression at 272664, data encryption at 16441, extended instructions at 19132, find prime numbers at 76, physics at 1174, and random string sorting at 33109.

Without any recorded benchmark scores for the Qualcomm Snapdragon X1P-66-100, the data cannot support a direct performance comparison. The head-to-head benchmark list is empty, and the wins counters are both zero.

The Verdict

The recorded data shows a clear performance hierarchy. The AMD Ryzen 7 PRO 8840U has a substantial benchmark presence with an average score of 32233 and an 83rd percentile ranking. Its nearest rivals are all Intel desktop and mobile processors with scores within a narrow 0.4% range, indicating the AMD chip performs at a mainstream desktop level.

The Qualcomm Snapdragon X1P-66-100 has no recorded benchmarks, an average score of zero, and a 50th percentile ranking. The 50th percentile is based on its specifications, not on measured performance. The lack of benchmark data means the database cannot establish its real-world standing.

For users who rely on measured performance data, the AMD Ryzen 7 PRO 8840U is the only chip with verified results. Its 16 threads and 5.10 GHz boost clock contribute to strong multi-threaded scores, as seen in the Cinebench R23 multicore result of 20254.

The Qualcomm Snapdragon X1P-66-100 offers a higher memory bandwidth of 135.2 GB/s and a larger per-core L1 cache, but these specifications do not translate into recorded benchmark scores. The database shows no evidence of its computational capabilities.

Where Each One Wins

The AMD Ryzen 7 PRO 8840U wins in all recorded benchmark categories because the Qualcomm Snapdragon X1P-66-100 has no benchmark entries. The AMD chip's 16 threads give it a clear advantage in multi-threaded workloads, as evidenced by the Cinebench R23 multicore score of 20254 and the PassMark multithread score of 23850.

The AMD processor is also the only one with verified single-thread performance. The PassMark single-thread score of 3641 and the Cinebench R23 single-core score of 2859 provide measurable data for tasks that depend on single-core speed, such as legacy applications or lightly threaded software.

The Qualcomm Snapdragon X1P-66-100 wins on paper in memory bandwidth, offering 135.2 GB/s versus the AMD chip's 89.6 GB/s. This specification advantage could benefit memory-intensive workloads, but the database contains no benchmark results to confirm this.

The Qualcomm chip also has a larger per-core L1 cache at 288 KB, compared to 64 KB on the AMD chip. The L2 cache is organized per module at 12 MB, which is larger than the AMD's 1 MB per core. These cache advantages are structural, not measured.

The AMD chip wins on PCIe lane count with 20 lanes versus 12 lanes on the Qualcomm chip. This gives the AMD processor more bandwidth for connected devices. The AMD chip also supports ECC memory, which the Qualcomm chip does not.

For users who need ECC memory support, the AMD Ryzen 7 PRO 8840U is the only option. For users who prioritize higher memory bandwidth and lower power consumption on paper, the Qualcomm Snapdragon X1P-66-100 has a nominal advantage, but the absence of benchmark data leaves that advantage unverified.
