The first Mini PC featuring AMD Ryzen AI 9 HX 370 APU has been tested and its Radeon 890M iGPU shines in gaming benchmarks.
AMD Ryzen AI 300 Mini PCs Deliver Much Capable Gaming Performance Thanks To Radeon 890M iGPU
It has been a few weeks since AMD launched its Zen 5-based Ryzen AI 300 APUs aka Strix-Point for gaming laptops and mobile platforms. Several notebook manufacturers have already announced new gaming laptops with the latest Strix APUs but we haven't seen a mini-PC being announced with one of these chips. Although the estimated date for these mini-PCs is early October, ETA Prime has showcased the first benchmarks for one of these Mini PCs before its official launch.
ETA Prime has recently uploaded a video reviewing an early sample of the SOUYO S9 mini-PC based on the latest A<D Ryzen AI HX 370 APU with a clock speed of 2.0/5.1GHz(Base/Boost). The SOUYO S9 is a compact box, featuring the Zen 5 and Zen 5c architecture-based processor with 12 cores and 24 threads.
The AMD Ryzen AI HX 370 has 4 Zen 5 and 8 Zen 5c cores and a Radeon 890M "RDNA 3" iGPU based on the RDNA 3.5 architecture overclockable up to 2900MHz. The RDNA 3.5 architecture brings 16 Compute Units for the Radeon 890M GPU, which makes it the current fastest iGPU in the market. This Mini PC will also be available with the standard Ryzen AI 9 365 configuration.
Other specs include a non-upgradeable LPDDR5X memory and three slots for PCI-E 4.0 NVMe SSDs. The SOUYO S9 can have three different memory configurations: 16 GB, 32 GB, or 64 GB sizes, and can feature either 6400 MT/s or 7500 MT/s clock speed (the tested configuration features 7500 MT/s speeds).
On the other hand, storage upgradeability is surprisingly good for a mini-PC as usually, most mini-PCs don't offer three M.2 slots. This early unit had problems with the middle M.2 slot and the front USB4 port was also not working but this is to be expected from early samples.
ETA Prime benchmarked the mini-PC in several synthetic software as well as modern titles to test the capability of the mini-machine. Thankfully, the mini-PC didn't lack anywhere and had stable performance across all the apps and video games. The power numbers during gaming ranged between 50-70W.
The performance was greatly improved over the last-gen Radeon 780M "RDNA 3" iGPU thanks to the new Radeon 890M "RDNA 3.5" graphics, which makes it a good fit for gaming without a discrete GPU. Here are the benchmark results of the synthetic apps and games (Credits: Videocardz):
| Apps/Games | Score/Avg FPS | Graphics Presets |
| Fire Strike | 10319 (Graphics) | - |
| Steel Nomad(DX12) | 625 | - |
| Time Spy | 3792 (Graphics) | - |
| CyberPunk 2077 | 80+ | 1080p, Low, FSR Balanced |
| Starfield | 78 | 1080p, Low, 50% RES, Frame Gen On |
| Hogwarts Legacy | 72 | 1080p, Low, FSR Balanced |
| Mortal Kombat 1 | 60 | 1080p, Med, FSR Balanced |
| Horizon Forbidden West | 60+ | 1080p, Low, Frame Gen On |
| Ghost of Tsushima | ~70 | 1080p, Med, FSR 3.1 Balanced, AMD Frame Gen On |
| Red Dead Redemption 2 | 76 | 1080p, Low, FSR Balanced |
The performance is noticeably better than the Radeon 780M since the architecture is better as well as the Compute Units are increased from 12CU to 16CU. The Mini PC can play modern titles at 1080p with 60+ fps using low to medium-quality settings, which is a remarkable performance for a mini-PC since you can only expect this level of performance with something like a GTX 1650 or similar GPUs.
The SOUYO S9 isn't yet officially available for purchase nor do we know its official price. Nonetheless, we can expect more such mini-PCs in October and possibly some handhelds based on the Ryzen AI 300 Strix Point CPUs pretty soon.
