Alienware started soldering components onto the boards so you cannot replace the CPU or GPU. To do any upgrades you have to replace the entire motherboard but only with one from the same series. The R4 was released with the 8000 series CPUs.
Even if they used a socket CPU, they would not be compatible between the 7th and 8th gen CPUs.
