AMD Radeon HD 8000 series

The Radeon HD 8000 series is a graphics card series from AMD . The only new chip is an as Oland designated graphics chip , the others were already in the Radeon HD 7000 series used. Therefore, it is largely a rebranding of the previous series. The graphics cards of the new series are only sold in the OEM market . Oland, like Cape Verde, Pitcairn and Tahiti, is a new 28 nm chip of the first generation of the GCN architecture.

Hardware compatible with OpenCL 2.0 such as AMD GCN architecture 2nd and 3rd generation supports the higher version 2.1 and also the new version 2.2 with updated drivers according to the Khronos Group. Current drivers such as Crimson 16.7.3 currently only support OpenCL 2.0. For the future, AMD also wants to support the first generation of the GCN with OpenCL 2.0. So far it is only enough for 1.2 with partial functions of 2.0.

OpenGL 4.5 is supported for the GCN architecture 1st to 3rd generation since the AMD Catalyst driver 15.30 WHQL. From driver version AMD Crimson 16.3.2, Vulkan 1.0 is also supported. AMD Adrenalin 18.3 and later supports OpenGL 4.6. Linux Mesa 20.0 supports OpenGL 4.6 with the RadeonSI sub-driver. With current drivers, parts of Vulkan 1.1 and 1.2 are also supported depending on the capabilities of the different variants of the first generation of the GCN.

Remarks

1. ↑ OEM products. All cards are not available in the retail market.
2. ↑ The date indicated is the date of the public presentation, not the date of availability of the models.
3. ↑ The specified performance values ​​for the computing power via the stream processors, the pixel and texel fill rate, and the memory bandwidth are theoretical maximum values ​​without "PowerTune", which are not directly comparable with the performance values ​​of other architectures. The overall performance of a graphics card depends, among other things, on how well the available resources can be used or fully utilized. There are also other factors that are not listed here that affect performance.
4. ↑ ^{a b} The specified clock rates are the reference data recommended or specified by AMD, the I / O clock is specified for the memory clock. However, the exact clock rate can deviate by a few megahertz due to different clock generators, and the final definition of the clock rates is in the hands of the respective graphics card manufacturer. It is therefore entirely possible that there are or will be graphics card models that have different clock rates.
