It rocks 8 cores, 16 threads, 16 MB of L3 cache and the Radeon RX 680M iGPU. The clock speeds are also the same, rated at 3.3 GHz base and 4.9 GHz boost but there's one difference and that's the TDP. The HS parts come with a 35W TDP while the HX parts are suited for 45W+. This means that the HX parts will have a slight advantage when it comes to clock stability while HS parts are usually thermally-constrained and will have to divide that power budget between the iGPU and the CPU.
