AMD Ryzen 9 8940HX
The AMD Ryzen 9 8940HX is a flagship 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 2.4 GHz to 5.3 GHz, along with a rather basic Radeon 610M RDNA 2 architecture iGPU. This Ryzen 9 8000 APU is essentially a Ryzen 9 7940HX with the Turbo clock speed increased by 100 MHz.
The 8940HX 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 8940HX as of April 2025, we do have some Cinebench benchmark scores for the 7940HX. Based on those, the newer Ryzen 9 should have no trouble beating the Core i9-13950HX, Core i9-13980HX and Core i9-14900HX.
That being said, with this many cores the APU will probably do a much better job serving content creators rather than gamers.
Power consumption
Much like the 7940HX, the 8940HX has a base TDP (long-term power limit) of 55 watts that can officially be jacked up to as high as 75 watts. To dissipate 50+ watts, at least one high-RPM fan is needed.
