AMD Ryzen 7 8745HX
The AMD Ryzen 7 8745HX is a higher-end octa-core Dragon Range refresh lineup processor that debuted in April 2025 and is primarily targeted at gaming laptops. This is essentially a rebadged Ryzen 7 7745HX; as such, the product offers 8 SMT-enabled Zen 4 cores (16 threads) running at 3.6 GHz to 5.1 GHz, along with a rather basic Radeon 610M RDNA 2 architecture iGPU.
This Ryzen 7 8000 APU is composed of two dies made on two different nodes (5 nm for CPU cores; 6 nm for other componentry). It features a very healthy 28 PCIe 5 lanes for connecting graphics cards and SSDs as fast as 15.75 GB/s. The RAM controller is limited to DDR5-5200 or slower; there is no NPU and no Thunderbolt support, the product page on amd.com indicates, but the clock multiplier is unlocked for easy overclocking.
Performance
While we have not tested a single system featuring the 8745HX as of April 2025, multi-threaded Cinebench benchmarks put the 7745HX in the same ballpark as the Core Ultra 9 285H, Core Ultra 9 185H and Core i5-13500HX which is fast enough for any 2025 game.
Power consumption
Much like the 7745HX, the 8745HX has a base TDP (long-term power limit) of 55 watts that can officially be jacked up to as high as 75 watts. That's precisely what Minisforum did with only 7745HX system Notebookcheck has tested so far. Either way, to dissipate 50+ watts, at least one high-RPM fan is needed.
