AMD Ryzen 9 8945HX

The AMD Ryzen 9 8945HX is the top 16-core Dragon Range refresh lineup laptop processor that debuted in April 2025. The product offers 16 SMT-enabled Zen 4 cores (32 threads) running at 2.5 GHz to 5.4 GHz, along with a rather basic Radeon 610M RDNA 2 architecture iGPU. This Ryzen 9 8000 APU is essentially a rebadged Ryzen 9 7945HX.
The 8945HX is composed of three 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 8945HX as of April 2025, we have reviewed multiple systems built around the 7945HX. In Cinebench benchmarks, it has no trouble leaving the mighty Ryzen AI Max+ 395 behind by a few percentage points.
With this many cores, the APU will probably do a much better job serving content creators rather than gamers.
Power consumption
Much like the 7945HX, the 8945HX has a base TDP (long-term power limit) of 55 watts that can officially be jacked up to as high as 75 watts. However, most of the 7945HX systems tested by Notebookcheck had an even higher value of 100+ watts. To dissipate this much heat, a couple of high-RPM fans are a must.
