Listed on HIS' own website, the RX 460 Slim-iCooler OC 4GB is based on AMD's smaller Polaris 11 GPU with 14 compute Units or 896 Stream Processors.
Despite using a slimmer single-slot cooler with metallic fan shroud and 50mm fan that does not spin up before GPU hits 60 C, HIS even manage to include a small factory-overclock, pushing the GPU to 1,220MHz while 4GB of GDDR5 memory with 128-bit memory interface remained at reference 7,000MHz.
While it won't run a lot of games at maximum settings and high resolution, the HIS RX 460 Slim-iCooler OC 4GB does not need additional PCIe power connector and should deal with most MOBA games quite well.
Unfortunately, we could not find the HIS RX 460 Slim-iCooler OC 4GB listed and the company did not provide any details regarding the price or the availability date.
