With VR heating up, companies have been looking for ways to provide an affordable entry, but VR requires a very different GPU than gaming on a screen. Meet ARM's new GPU - the Mali-G51 - built specifically for VR. A smaller brother of the G71, this is the second GPU to use the new Bifrost architecture built with Vulkan in mind. This one is more than just a G71 with fewer cores, in fact it's the first to use a dual shader architecture. Basically, traditional shaders process one pixel per clock cycle. Mali-G51's shaders can do two pixels per clock while using fewer resources (both in...
