![]() ![]() Tahiti has a maximum ¼ double precision throughput relative to its single precision throughput, while the other two smaller consumer dies can only achieve a 1/16 ratio. While this gives roughly a doubling of single-precision floating point, there is however a significant departure in double-precision compute power. The 28 nm product line is divided in three dies ( Tahiti, Pitcairn, and Cape Verde), each one roughly double in shader units compared to its small brethren (32, 20, and respectively 10 GCN compute units). The die and package of a Radeon HD 7870 graphics card. or 1.2 and higher) will be supported with actual drivers in 2018 (here only HD 7790). Vulkan (API)ĪPI Vulkan 1.0 is supported for all with GCN Architecture. or 1.2 and higher) For OpenCL 2.1 and 2.2 only Driver Updates are necessary with OpenCL 2.0 conformant Cards. OpenCL 2.0 is supported with GCN 2nd Gen. Open CL 1.0 to 1.2 are supported for all Chips with Terascale and GCN Architecture. OpenCL accelerates many scientific Software Packages against CPU up to factor 10 or 100 and more. Video Accelerationīoth Unified Video Decoder (UVD) and Video Coding Engine (VCE) are present on the dies of all products and supported by AMD Catalyst and by the free and open-source graphics device driver#ATI/AMD. The AMD Eyefinity-branded on-die display controllers were introduced in September 2009 in the Radeon HD 5000 Series and have been present in all products since. These are implemented by emulation on some TeraScale (microarchitecture) GPUs. OpenGL 4.x compliance requires supporting FP64 shaders.A GPU implementing TeraScale (microarchitecture) version "Northern Island (VLIW4)" is found on APUs whose GPUs are branded with the Radeon HD 7000 series.A GPU implementing TeraScale (microarchitecture) version "Evergreen (VLIW5)" is found on Radeon HD 7670 and below branded discrete GPUs.A GPU implementing Graphics Core Next is found on the Radeon HD 7730 and above branded discrete GPUs.Graphics Core Next was introduced with the Radeon HD 7000 Series. ![]() This article is about all products under the Radeon HD 7000 Series brand. ![]()
