Minisforum BD795i SE review: The Mini-ITX desktop mainboard with an AMD Ryzen 9 CPU as a DIY solution for gaming mini PCs
AMD Ryzen 9 7945HX | AMD Radeon 610M
The AMD Ryzen 9 7945HX is a fast high-end laptop processor of the Dragon Range series. It offers 16 cores based on the Zen 4 architecture that supports hyperthreading (32 threads). The cores clock from 2.5 (base) up to 5.4 GHz (single core boost). The 7945HX is the fastest mobile Ryzen CPU at launch and derived from the desktop Ryzen 9 7950X.
The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible cores) in 5nm and an IO-die (including the memory controller and the Radeon 610M iGPU) in 6nm. The chip integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB4), 28 PCIe 5.0 lanes (for GPU and SSDs) and a dual-channel DDR5-5200 memory controller.
Performance
The Ryzen 9 7945HX is among the fastest processors in our database, as of August 2023. It is in the same league as the Ryzen 9 7945HX3D and noticeably ahead of the Core i9-13980HX, as far as multi-thread benchmark scores are concerned. It is outrageously, unbelievably fast, and those fortunate enough to purchase a laptop built around this CPU will have no performance issues for at least three years.
Thanks to its powerful cooling solution and a long-term CPU power limit of 128 W, the ROG Strix Scar 17 G733PY-XS96 is one of the fastest laptops built around the 7945HX that we know of.
The R9 7945HX is rated at a TDP of 55 Watt and can be configured up to 75 Watt (cTDP).
