AMD Ryzen 5 PRO 8645HS vs Qualcomm Snapdragon X1P-64-100 Comparison

The Verdict

The benchmark database places the AMD Ryzen 5 PRO 8645HS and the Qualcomm Snapdragon X1P-64-100 in different performance tiers. The AMD part holds an 82nd percentile ranking among all CPUs, while the Snapdragon sits at the 50th percentile. The Ryzen 5 PRO 8645HS is the clear choice for compute-heavy mobile workloads, as it delivers a fully populated benchmark profile across Cinebench and PassMark suites. The Snapdragon X1P-64-100, with no recorded benchmark scores in the database, cannot be positioned as a performance alternative. Users requiring verified multi-threaded and single-threaded performance data should select the AMD processor. Those prioritizing a lower thermal envelope (35 W TDP versus 45 W) and higher memory bandwidth (135.2 GB/s versus 89.6 GB/s) may consider the Snapdragon, but only if they accept the absence of benchmark validation in this database.

Architecture Differences

The AMD Ryzen 5 PRO 8645HS uses the Zen 4 architecture under the Hawk Point codename, part of the 8000 series. It is built by TSMC on a 4 nm process node, with 25,000 million transistors on a 178 mm² die. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The integrated graphics are the Radeon 760M, and the processor uses the AMD Socket FP7.

The Qualcomm Snapdragon X1P-64-100 uses the Oryon codename and belongs to the Snapdragon X (Plus) generation. It is also built by TSMC on a 4 nm process node, but the database lists no transistor count or die size. Its cache hierarchy differs substantially: 288 KB of L1 per core, 12 MB of L2 per module, and 6 MB of shared L3. The integrated graphics are the Adreno X1-85, and the socket is Qualcomm BGA 2073.

The process node is identical at 4 nm for both, and both use TSMC as the foundry. The architectural split is otherwise wide: Zen 4 with simultaneous multithreading on 6 cores versus Oryon with 10 physical cores and no threading. The AMD design allocates a smaller per-core L1 and L2 but a larger shared L3 pool. The Snapdragon design uses a significantly larger per-core L1 and per-module L2, with a smaller L3. These cache structures point to different design priorities, with AMD favoring a shared pool for thread-rich workloads and Qualcomm emphasizing per-core capacity.

Specification Differences

The two processors differ across nearly every recorded specification field. The AMD Ryzen 5 PRO 8645HS has 6 cores and 12 threads, while the Qualcomm Snapdragon X1P-64-100 has 10 cores and 10 threads. Base clocks are 4.30 GHz for AMD and 3.40 GHz for Qualcomm. The AMD part lists a boost clock of 5.00 GHz; the Qualcomm part lists none.

Thermal design power differs, with AMD at 45 W and Qualcomm at 35 W. The AMD processor uses AMD Socket FP7, while the Qualcomm uses Qualcomm BGA 2073. Memory support diverges: DDR5 for AMD versus LPDDR5X for Qualcomm. Memory bandwidth favors Qualcomm at 135.2 GB/s versus 89.6 GB/s for AMD. ECC memory is supported only on the AMD part. PCIe lanes differ as well, with AMD offering Gen 4 with 20 lanes (CPU only) and Qualcomm offering Gen 4 with 12 lanes (CPU only).

Cache specifications are not shared between the two. AMD provides 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Qualcomm provides 288 KB L1 per core, 12 MB L2 per module, and 6 MB shared L3. The integrated graphics units are the Radeon 760M for AMD and the Adreno X1-85 for Qualcomm. Neither processor has an unlocked multiplier. Release dates are close: AMD on 2024-04-15 and Qualcomm on 2024-04-23. The AMD part has a listed part number of 100-000001315 (FP7r2) and 100-000001388 (FP7), while the Qualcomm part number is X1P64100.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, and the Qualcomm Snapdragon X1P-64-100 has no recorded benchmark scores. As a result, direct comparisons must rely on the AMD processor's measured results and its position among rivals.

The AMD Ryzen 5 PRO 8645HS delivers a Cinebench R23 multi-core score of 19742 and a single-core score of 2787. In Cinebench R20, it scores 8291 multi-core and 1170 single-core. The older Cinebench R15 run shows 1989 multi-core and 280 single-core. PassMark results include a multithread score of 23569, a single-thread score of 3858, integer math at 72740, floating point math at 45481, and extended instructions at 21212. Data compression reaches 265826, data encryption 17387, physics 1208, find prime numbers 73, and random string sorting 35472.

The average benchmark score for the AMD processor is 30879, placing it at the 82nd percentile of all CPUs. Its nearest rivals in the database are the AMD Ryzen 7 8700F with an average score of 30746 (0.4% behind), the Intel Core i7-13700TE with 31028 (0.5% ahead), the AMD Ryzen 9 8945HS with 31074 (0.6% ahead), and the Intel Core i7-12700F with 31081 (0.6% ahead). These deltas are all within one percentage point, indicating that the Ryzen 5 PRO 8645HS sits in a tightly packed performance band around the 31,000 average score mark.

The Qualcomm Snapdragon X1P-64-100 has no recorded scores, an average benchmark score of zero, and no nearest rivals listed. Its 50th percentile ranking appears in the database, but without benchmark entries, there are no wins to attribute to it in any test category.

Where Each One Wins

The AMD Ryzen 5 PRO 8645HS wins every category where measured data exists. It shows strong multi-threaded capability with a Cinebench R23 multi-core score of 19742 and a PassMark multithread score of 23569. Single-thread performance is also solid, with a Cinebench R23 single-core score of 2787 and a PassMark single-thread score of 3858. The processor's nearest rival comparisons show it within 0.6% of the Intel Core i7-12700F and the AMD Ryzen 9 8945HS, confirming that it competes at the upper edge of its class. The 82nd percentile ranking reinforces this position.

The Qualcomm Snapdragon X1P-64-100 wins only in specification-based categories, as no benchmark data exists. It offers a lower TDP of 35 W versus 45 W, which indicates a smaller thermal footprint for system designers. Its memory bandwidth of 135.2 GB/s exceeds the AMD part's 89.6 GB/s by a wide margin, which could benefit memory-bound operations if software is optimized for the platform. The 10-core configuration without simultaneous multithreading provides more physical cores than the AMD's 6, but the database records no tests to show whether that translates into real performance gains.

For users who need verified performance numbers, the AMD Ryzen 5 PRO 8645HS is the only option with data in the database. For users who prioritize the lower thermal design power and the higher memory bandwidth, the Snapdragon X1P-64-100 offers those attributes, but the absence of benchmark scores leaves its actual compute performance unverified. The AMD part also provides ECC memory support, a feature the Qualcomm part lacks, and a higher PCIe lane count at 20 lanes versus 12 lanes, both of which are relevant for workstation-class mobile systems.
