Other wins for the Ryzen AI 9 HX 375 include data compression (404,918 versus 386,811, a 4.5% edge), physics (1,819 versus 1,647, a 9.5% edge), prime numbers (122 versus 103, a 15.6% edge), and extended instructions (29,269 versus 29,067, a narrow 0.7% edge). The multi-thread PassMark score also favors the mobile chip, 32,916 versus 31,690, a 3.7% margin.

The overall average benchmark scores reflect these results. The Ryzen AI 9 HX 375 averages 46,030 across all recorded tests, placing it in the 89th percentile of all CPUs. The Ryzen 7 8700G averages 33,089, sitting in the 83rd percentile. Notably, the 8700G's nearest rivals include the Intel Core i7-13650HX and AMD Ryzen 7 7745HX, both with an average score of 33,089 (0% delta), plus the AMD Ryzen 7 7800X3D at 33,079 (0% delta). The Ryzen AI 9 HX 375's nearest rivals are the Intel Core Ultra 5 235 (46,062, -0.1% delta), Intel Core i9-13900HX (46,098, -0.1% delta), and two AMD EPYC server parts within 0.2%.

Where Each One Wins

The Ryzen AI 9 HX 375 dominates in workloads that scale with core count and sustained multi-thread throughput. Its 12 cores and 24 threads, combined with a Zen 5 architecture, deliver consistently higher scores in Cinebench multi-core tests, integer and floating-point math, data compression, physics simulation, and prime number calculation. These results point to productivity tasks, content creation, and heavy parallel processing as its natural territory.

The Ryzen 7 8700G wins in several single-thread and latency-sensitive workloads. Its Geekbench single-core advantage of 12.1% is the largest single-thread margin recorded in this comparison. It also holds the edge in PassMark single-thread tests and random string sorting, which often responds to memory latency and per-core efficiency. The data encryption win of 9.8% suggests the desktop part's memory subsystem handles certain cryptographic operations more effectively despite the mobile chip's higher memory bandwidth rating of 89.6 GB/s versus 83.2 GB/s.

The split in Geekbench results is worth noting: the 8700G wins both single-core and multi-core there, while the Ryzen AI 9 HX 375 wins both Cinebench multi-core tests and most PassMark multi-thread tests. This divergence suggests the two processors respond differently to the specific instruction mixes and threading patterns of each benchmark suite. The Ryzen 7 8700G's unlocked multiplier, a feature absent on the Ryzen AI 9 HX 375, could allow users to further adjust performance on the desktop platform, though the recorded data does not quantify such overclocking gains.

Specification Differences

The two processors differ in several core specifications. The Ryzen 7 8700G uses 8 cores and 16 threads, while the Ryzen AI 9 HX 375 uses 12 cores and 24 threads. Base clocks differ substantially: 4.20 GHz for the desktop part versus 2.00 GHz for the mobile part, though both boost to 5.10 GHz. The TDP ratings are 65 watts for the 8700G and 28 watts for the Ryzen AI 9 HX 375.

The socket types are incompatible: the 8700G mounts on AMD Socket AM5, while the Ryzen AI 9 HX 375 uses AMD Socket FP8. The market segments also differ, with the 8700G classified as Desktop and the Ryzen AI 9 HX 375 as Mobile. The desktop chip has an unlocked multiplier, while the mobile chip does not. The 8700G carries a launch MSRP of $329; no launch MSRP is recorded for the Ryzen AI 9 HX 375.

Memory support differs in scope. The 8700G supports DDR5, while the Ryzen AI 9 HX 375 supports both DDR5 and LPDDR5X. Memory bandwidth ratings show 83.2 GB/s for the desktop part and 89.6 GB/s for the mobile part. PCIe lane counts also differ: the 8700G provides 20 Gen 4 lanes (CPU only), while the Ryzen AI 9 HX 375 provides 16 Gen 4 lanes (CPU only). Integrated graphics differ as well, with the 8700G using Radeon 780M and the Ryzen AI 9 HX 375 using Radeon 890M.

The die size and cache structures show notable differences. The 8700G has a die size of 178 mm², while the Ryzen AI 9 HX 375 measures 233 mm². L1 cache is 64 KB per core on the 8700G and 80 KB per core on the Ryzen AI 9 HX 375. Both have 1 MB L2 per core and 16 MB shared L3. The transistor count is recorded as 25,000 million for the 8700G; no transistor count is recorded for the Ryzen AI 9 HX 375. Release dates differ, with the 8700G launching earlier and the Ryzen AI 9 HX 375 following later in 2024.

Architecture Differences

The architectures diverge at the generation level. The Ryzen 7 8700G belongs to the 8000 series and uses Zen 4 architecture under the Phoenix codename. The Ryzen AI 9 HX 375 belongs to the Ryzen AI 300 generation and uses Zen 5 architecture under the Strix Point codename, specifically a hybrid arrangement of Zen 5 and Zen 5c cores. Both processors are manufactured on a 4 nm process node by TSMC.

The cache hierarchy reflects the architectural shift. The Zen 5-based chip increases L1 per core from 64 KB to 80 KB, while keeping L2 at 1 MB per core and L3 at 16 MB shared. The die size grows from 178 mm² to 233 mm², accommodating the additional cores and the larger L1 allocation. The mobile chip's hybrid core design, combining Zen 5 and Zen 5c, explains its higher core count of 12 versus 8 while maintaining a lower base clock of 2.00 GHz.

The integrated graphics also differ by generation. The 8700G uses Radeon 780M, while the Ryzen AI 9 HX 375 uses Radeon 890M. The memory controller on the mobile chip adds LPDDR5X support, which the desktop part lacks. The PCIe implementation is slightly reduced on the mobile chip, with 16 Gen 4 lanes compared to 20 on the desktop part. The unlocked multiplier on the 8700G reflects its desktop positioning, while the locked multiplier on the Ryzen AI 9 HX 375 aligns with mobile platform constraints. Both chips lack 3D V-Cache and ECC memory support, and both are currently in active production.
