![]() Many software and BIOS updates as well as improved cache all somewhat aid tessellation performance and extend the staying power of second-generation GCN cards. The theoretical geometry performance was almost doubled with four geometry engines (instead of two in GCN 1) and the number of render output units (ROPs) was also increased. One of the many additions was True Audio, which might as well be called ‘Awesome audio’, even if it is, unfortunately, seeing limited use in current games. Many new features were added and revamped, chip leakage was reduced and die-size optimization reached its peak. GCN is a very complex and powerful architecture, so software-wise it took (and is still taking with each new release) a long time to fully mature. #Dx12 fp64 usage drivers#On release, it was more efficient and faster in every way to Cayman’s VLIW4, but that speed came with a price: drivers couldn’t keep pace, which lessened the anticipated gains. Graphics Core Next, however, fully addressed the compute issues whilst being a great gaming design as well. It also had underutilization issues with some newer game titles (partially solved in its last iteration). #Dx12 fp64 usage serial#Sure, it could do some of them proficiently, but the more serial or complex tasks would run very slowly. The generation that preceded GCN, VLIW was a graphics powerhouse, but it had real issues with compute-heavy workloads. The very core of GCN 1 is still in use in refined form, and can be found in all subsequent versions. It was also the first DX11.1 GPU (which makes it work fine with Vulkan and DX12, might I add) and AMD’s entrance into the Compute market. The chip was manufactured based on a new process, featuring the first entirely new architecture since 2006. Seen in: Oland, Cape Verde, Tahiti, Pitcairnīasically the entire 7000 series from the HD 7730 and up and barring the HD 7790 and then R9 280 and 280X.ĭebuting with the first 28nm video card, the AMD HD 7970, this was a pivotal moment for AMD and GPUs in general. While those matter too, they aren’t strictly architectural per se.Ī good overview of the general improvements GCN has received. So today we will be taking a look at just such improvements, with node shrinks and process optimizations left aside. Obviously, though, no single architecture can survive without refinements and changes being made over time. It has proven itself to be quite the tough and scalable design, and versions of it are in use with the Playstation and Xbox One as well as many computers. Tweet AMD’s Graphics Core Next (shortened to GCN) architecture has been a mainstay for several years now. ![]()
