Architecture Differences

The AMD Ryzen 7 PRO 8840HS uses the Zen 4 architecture under the Hawk Point codename, manufactured on a 4 nm process at TSMC. It integrates 25,000 million transistors on a die size of 178 mm². The Qualcomm Snapdragon X1E-78-100 uses the Oryon codename, part of the Snapdragon X (Elite) generation, also built on a 4 nm process at TSMC, but the database records no transistor count or die size for it.

The AMD chip belongs to the 8000 series and uses AMD Socket FP7. The Qualcomm part uses Qualcomm BGA 2073. Core organization differs substantially: the AMD processor provides 8 cores with 16 threads, while the Qualcomm processor provides 12 cores with 12 threads. This means the AMD part can process two threads per core, whereas the Qualcomm part operates with one thread per core.

Cache design is not directly comparable. The AMD Ryzen 7 PRO 8840HS allocates 64 KB of L1 per core and 1 MB of L2 per core, with a shared 16 MB L3 pool. The Qualcomm Snapdragon X1E-78-100 allocates 288 KB of L1 per core and 12 MB of L2 per module, with a smaller shared 6 MB L3. The larger per-core L1 on the Qualcomm part suggests a different latency strategy, while the AMD part has a larger shared L3.

Memory support differs by type and bandwidth. The AMD processor uses DDR5 in a dual-channel configuration, achieving 89.6 GB/s. The Qualcomm processor uses LPDDR5X, also dual-channel, but achieves 135.2 GB/s, which is a 51% higher theoretical memory bandwidth. The Qualcomm part does not support ECC memory, while the AMD part does.

PCIe connectivity also differs. The AMD Ryzen 7 PRO 8840HS provides Gen 4 with 20 lanes from the CPU, while the Qualcomm Snapdragon X1E-78-100 provides Gen 4 with 12 lanes from the CPU. Integrated graphics differ as well: the AMD part includes Radeon 780M graphics, while the Qualcomm part includes Adreno X1-85.

The AMD processor has a base clock of 3.30 GHz and a boost clock of 5.10 GHz. The Qualcomm processor has a base clock of 3.40 GHz and no recorded boost clock. The AMD part has a TDP of 28 watts, while the Qualcomm part has a TDP of 35 watts. Both are active production parts for the mobile market, and both were released in April 2024, with the AMD part dated April 15 and the Qualcomm part dated April 23.

The Verdict

The recorded data shows a clear separation between the two processors. The AMD Ryzen 7 PRO 8840HS has benchmark results across 15 tests, an average benchmark score of 39,603, and a percentile rank of 87 among all CPUs. The Qualcomm Snapdragon X1E-78-100 has no recorded benchmark scores in the database, an average benchmark score of 0, and a percentile rank of 50.

For users who need documented single-thread and multi-thread performance, the AMD processor is the only one with measured data. Its nearest rivals in the database include the AMD Ryzen AI 7 450 with an average score of 39,485, which is 0.3% below the 8840HS, and the AMD Ryzen 7 9800X3D with an average score of 39,768, which is 0.4% above it. These close margins place the 8840HS directly in the middle of a tight performance cluster.

The Qualcomm Snapdragon X1E-78-100 cannot be evaluated on the same basis because the database contains no benchmark records for it. Its 50th percentile rank and zero average score indicate an absence of measured data rather than a measured performance level. The AMD part also has a higher percentile rank, 87 versus 50, which reflects its position among all CPUs that have been tested.

Choosing between them depends on whether benchmark evidence matters. The AMD Ryzen 7 PRO 8840HS has a full suite of scores, a defined boost clock, ECC memory support, and a lower TDP of 28 watts. The Qualcomm part offers more cores, higher base clock, and higher memory bandwidth, but none of those advantages are backed by recorded benchmark scores. The data supports the AMD processor for anyone who needs verified performance metrics.

Specification Differences

The two processors differ in nearly every major specification category. The AMD Ryzen 7 PRO 8840HS has 8 cores and 16 threads; the Qualcomm Snapdragon X1E-78-100 has 12 cores and 12 threads. Base clocks are 3.30 GHz for the AMD part and 3.40 GHz for the Qualcomm part. The AMD part has a boost clock of 5.10 GHz; the Qualcomm part has none recorded. TDP is 28 watts versus 35 watts.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Ryzen 7 PRO 8840HS and the Qualcomm Snapdragon X1E-78-100. The head-to-head field is empty, and neither processor records a win in a direct comparison. However, the AMD processor has 15 individual benchmark scores, while the Qualcomm processor has none.

The AMD Ryzen 7 PRO 8840HS scores 14,784 in Cinebench R23 multi-core and 1,724 in Cinebench R23 single-core. In Cinebench R15, it scores 2,458 multi-core and 271.5 single-core. PassMark results include 266,46 in multithread, 3,692 in single thread, 93,342 in integer math, 55,739 in floating point math, 22,298 in extended instructions, and 18,838 in data encryption. It also records 311,199 in data compression, 37,922 in random string sorting, 1,351 in physics, and 84 in find prime numbers.

The average benchmark score for the AMD processor is 39,603. Its nearest rivals show how tightly grouped this performance tier is: the AMD Ryzen AI 7 450 averages 39,485, which is 0.3% lower; the AMD Ryzen 7 PRO 8845HS averages 39,325, which is 0.7% lower; and the AMD EPYC 4245P averages 39,215, which is 1% lower. The AMD Ryzen 7 9800X3D averages 39,768, which is 0.4% higher.

The Qualcomm Snapdragon X1E-78-100 has no recorded scores in any test category. Its average benchmark score is 0, and it has no nearest rivals listed. The absence of data is the defining feature of its benchmark profile. Without recorded measurements, no direct comparison of performance deltas is possible.

Where Each One Wins

The AMD Ryzen 7 PRO 8840HS wins in every category where recorded data exists. It has a full benchmark suite, a 5.10 GHz boost clock, ECC memory support, 20 PCIe Gen 4 lanes, a lower TDP of 28 watts, and an 87th percentile ranking. Its nearest rival comparisons show it performs within 1% of several other AMD processors, including the Ryzen AI 7 450, Ryzen 7 9800X3D, Ryzen 7 PRO 8845HS, and EPYC 4245P, which situates it in a competitive performance band.

The Qualcomm Snapdragon X1E-78-100 wins on specification points that do not require benchmark data. It has 12 cores versus 8, a base clock of 3.40 GHz versus 3.30 GHz, and memory bandwidth of 135.2 GB/s versus 89.6 GB/s. It also has a larger L1 cache per core at 288 KB versus 64 KB. These are raw architectural advantages, but they are unverified by any recorded performance test.

The AMD processor wins for users who require measured performance evidence, multithreading capability, ECC memory, or a lower power envelope. The Qualcomm processor wins for users who prioritize core count, memory bandwidth, or base clock speed on paper. The database records no benchmark results for the Qualcomm part, so its specification advantages cannot be confirmed in practice. The AMD Ryzen 7 PRO 8840HS is the only one of the two with recorded data supporting its performance claims.
