AMD unveils new Ryzen 8040HX laptop CPUs with up to 16 cores at 5.4GHz
AMD's latest Ryzen 8040HX laptop processors succeed the Ryzen 7045HX, also known as "Dragon Range." Although a year and a half have passed since the latter was released, there are hardly any changes. Just like the AMD Ryzen 9 7945HX, the Ryzen 9 8945HX has 16 performance cores based on the Zen 4 architecture, a 80MB cache and adjustable TDP between 55 and 75 watts.
The integrated Radeon 610M iGPU also remains unchanged. This graphics chip isn't powerful enough to smoothly render current games, but AMD's HX chips are typically paired with a dedicated graphics chip anyway. Even the clock speeds remain unchanged. AMD advertises a base clock of 2.5GHz and a boost clock up to 5.4GHz. AMD's latest processor lineup for laptops includes the following four chipsets:
| CPU | Cores / Threads | Base clock | Boost clock | Cache | iGPU | TDP |
|---|---|---|---|---|---|---|
| AMD Ryzen 9 8945HX | 16 / 32 | 2.5GHz | 5.4GHz | 80MB | Radeon 610M | 55W – 75W |
| AMD Ryzen 9 8940HX | 16 / 32 | 2.4GHz | 5.3GHz | 80MB | Radeon 610M | 55W – 75W |
| AMD Ryzen 7 8840HX | 12 / 24 | 2.9GHz | 5.1GHz | 76MB | Radeon 610M | 45W – 75W |
| AMD Ryzen 7 8745HX | 8 / 16 | 3.6GHz | 5.1GHz | 40MB | Radeon 610M | 45W – 75W |
The Ryzen 9 8940HX is basically a rebadged Ryzen 9 7940HX, but with 100MHz higher boost clock speeds that have already been revealed by a listing for the upcoming Asus ROG Strix G16. The Ryzen 7 8840HX is practically identical to the Ryzen 9 7845HX, and the Ryzen 7 8745HX corresponds to the Ryzen 7 7745HX.
All mentioned AMD processors support up to 64GB DDR5-5200 memory and 28 PCIe 5.0 lanes. Consequently, this release doesn't offer any noteworthy innovations apart from new model numbers, as the performance should remain mostly unchanged.
