Architecture Differences

The AMD Ryzen 7 PRO 8840HS and the Qualcomm Snapdragon X1E-80-100 represent two fundamentally different design approaches. The AMD part uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. It integrates 25,000 million transistors on a 178 mm² die. The Qualcomm Snapdragon X1E-80-100 uses the Oryon codename and belongs to the Snapdragon X Elite generation, also fabricated on a 4 nm process at TSMC, though its transistor count and die size are not recorded in the database.

Core organization differs substantially. The AMD chip provides 8 cores with 16 threads, relying on simultaneous multithreading to double its thread count. The Qualcomm chip provides 12 physical cores with 12 threads, meaning each core operates as a single thread without SMT support. This creates a tradeoff: Qualcomm offers more physical cores, while AMD offers more threads.

Cache hierarchies also diverge. The AMD Ryzen 7 PRO 8840HS uses 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Qualcomm Snapdragon X1E-80-100 uses 288 KB of L1 cache per core, 12 MB of L2 cache per module, and only 6 MB of shared L3 cache. The AMD chip's larger L3 pool benefits workloads that repeatedly access shared data, while the Qualcomm design allocates more cache at the L1 and L2 levels.

Platform support differs significantly. The AMD processor uses AMD Socket FP7, supports dual-channel DDR5 memory with 89.6 GB/s bandwidth, includes ECC memory support, and provides PCIe Gen 4 with 20 CPU lanes. The Qualcomm processor uses Qualcomm BGA 2073, supports dual-channel LPDDR5X memory with 135.2 GB/s bandwidth, lacks ECC support, and provides PCIe Gen 4 with 12 CPU lanes. The higher memory bandwidth on the Qualcomm side could help memory-intensive tasks, while AMD's extra PCIe lanes offer more connectivity headroom.

Both processors are unlocked multipliers set to false, and both target the mobile market segment. Their production status is Active, with release dates roughly one week apart in April 2024.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for these two processors. The AMD Ryzen 7 PRO 8840HS has an extensive benchmark suite, while the Qualcomm Snapdragon X1E-80-100 has no recorded benchmark scores. This absence of comparative data means the head-to-head comparison relies entirely on the AMD processor's measured performance and the architectural differences listed above.

The AMD Ryzen 7 PRO 8840HS achieves notable scores across multiple workloads. In Cinebench R23, it scores 14,784 points in multicore and 1,724 points in single-core. In Cinebench R15, it scores 2,458 points multicore and 271.5 points single-core. PassMark results show 93,342 in integer math, 55,739 in floating point math, 26,646 in multithreaded tests, and 3,692 in single-thread tests. Additional PassMark scores include 311,199 in data compression, 18,838 in data encryption, 22,298 in extended instructions, 84 in find prime numbers, 1,351 in physics, and 37,922 in random string sorting.

The AMD processor's average benchmark score is 39,603, placing it in the 87th percentile of all CPUs tracked in the database. Its nearest rivals include the AMD Ryzen AI 7 450 with an average score of 39,485 (0.3% behind), the AMD Ryzen 7 9800X3D with 39,768 (0.4% ahead), the AMD Ryzen 7 PRO 8845HS with 39,325 (0.7% behind), and the AMD EPYC 4245P with 39,215 (1.0% behind). These tight margins indicate the Ryzen 7 PRO 8840HS sits in a competitive cluster among high-end processors.

The Qualcomm Snapdragon X1E-80-100 has an average benchmark score of 0 and sits at the 50th percentile, with no nearest rivals recorded. This means the database cannot confirm its performance level, and any comparison must acknowledge this lack of measured data.

The Verdict

The AMD Ryzen 7 PRO 8840HS is the only one of these two processors with recorded benchmark data, and that data is strong. Its 87th percentile ranking places it among upper-tier CPUs, and its average score of 39,603 shows consistency across a wide range of tests. The Qualcomm Snapdragon X1E-80-100 has no benchmark scores in the database, so its performance cannot be verified from recorded measurements.

For workloads where raw performance is the priority, the AMD Ryzen 7 PRO 8840HS is the clear choice based on available data. Its 16 threads, 5.10 GHz boost clock, and 16 MB of L3 cache provide a solid foundation for both single-thread and multithreaded tasks. The 28 W TDP also indicates efficient operation for a mobile processor.

The Qualcomm Snapdragon X1E-80-100 offers advantages in specific areas: 12 physical cores, a higher base clock of 3.40 GHz, significantly higher memory bandwidth at 135.2 GB/s, and a larger L1 cache per core. For applications that can use many physical cores without relying on SMT, or that heavily depend on memory bandwidth, this design may have merit. However, without benchmark scores to confirm these theoretical advantages, the recorded data favors the AMD processor.

The choice depends on whether the user prioritizes verified performance or specific architectural features. The AMD Ryzen 7 PRO 8840HS delivers measured results across the board. The Qualcomm Snapdragon X1E-80-100 brings a different core and memory configuration, but its actual performance remains unmeasured in the database.

Where Each One Wins

The AMD Ryzen 7 PRO 8840HS wins in scenarios that benefit from its higher boost clock, SMT support, larger L3 cache, and ECC capability. Its 5.10 GHz boost clock provides strong single-thread performance, which is important for applications like web browsing, office productivity, and lightly threaded creative tools. The 16 threads allow better handling of heavily multithreaded workloads such as video encoding, 3D rendering, and software compilation. The 16 MB L3 cache helps workloads with repeated data access patterns, and ECC support suits reliability-focused environments. The lower 28 W TDP also indicates more efficient operation, which matters for battery life in thin-and-light laptops.

The Qualcomm Snapdragon X1E-80-100 wins in scenarios where its architectural strengths are relevant. The 12 physical cores provide raw core count for workloads that scale with many threads but do not benefit from SMT. The higher base clock of 3.40 GHz gives it a steady operating frequency under sustained loads. The 135.2 GB/s memory bandwidth is substantially higher than AMD's 89.6 GB/s, which can benefit memory-bound workloads such as large data processing, AI inference, and certain scientific computing tasks. The 288 KB L1 cache per core is larger than AMD's 64 KB per core, which can help latency-sensitive single-thread tasks that repeatedly access small data sets. The 6 MB L3 cache is smaller than AMD's 16 MB, but the larger L1 and L2 allocations may compensate in some access patterns.

The database records no benchmark wins for either processor, so these distinctions are based on specification analysis rather than measured performance. The AMD Ryzen 7 PRO 8840HS is the only one of the two with verified scores, and those scores place it in the top tier of CPUs. The Qualcomm Snapdragon X1E-80-100 offers a different feature set, but its performance remains unconfirmed in the database. Users who require verified performance data should select the AMD processor. Users who value the Qualcomm chip's specific memory bandwidth, physical core count, or cache distribution may consider it, but they should be aware that its benchmark results are not recorded.
