provide more flexible geometry processing and replace the vertex and geometry shaders in a rendering pipeline. As of December 2018, the Primitive shaders can't be used because required API changes are yet to be done. Vega 10 and Vega 12 use the 14 nm FinFET process, developed by Samsung Electronics and licensed to GlobalFoundries. Vega 20 uses the 7 nm FinFET process developed by TSMC. Chips discrete GPUs: Vega 10 (14 nm Samsung/GloFo FinFET process) (also codenamed Greenland) found on "Radeon RX Vega 64", "Radeon RX Vega 56", "Radeon Vega Frontier Edition", "Radeon Pro V340", Radeon Pro WX 9100, and Radeon Pro WX 8200 graphics cards Vega 12 (14 nm Samsung/GloFo FinFET process) found on "Radeon Pro Vega 20" and "Radeon Pro Vega 16"-branded mobile graphics cards Vega 20 (7 nm TSMC FinFET process) found on "Radeon Instinct MI50" and "Radeon Instinct MI60"-branded accelerator cards, "Radeon Pro Vega II", and "Radeon VII"-branded graphics cards. integrated into APUs: Raven Ridge came with VCN 1 which supersedes VCE and UVD and allows full fixed-function VP9 decode. Precision performance Double-precision floating-point (FP64) performance of all GCN 5th generation GPUs, except for Vega 20, is 1/16 of FP32 performance. For Vega 20 with Radeon Instinct this is 1/2 of FP32 performance. For Vega 20 with Radeon VII this is 1/4 of FP32 performance. All GCN 5th generation GPUs support half-precision floating-point (FP16) calculations which is double of FP32 performance. Comparison of GCN chips Table contains only discrete GPU chips (including mobile). APU(IGP) and console chips are not listed. 1 Old code names such as Treasure (Lexa) or Hawaii Refresh (Ellesmere) are not listed. 2 Initial launch date. Launch dates of variant chips such as Polaris 20 (April 2017) are not listed.
