History
Predecessor Radeon 500 Series
Successor Navi Architecture

The AMD RX Vega series is a series of consumer graphics processors produced by AMD. These cards use the Vega architecture, feature HBM2 high-speed memory[7] and are based on the 14nm FinFET architecture.[8] Vega is the first to use the new Graphics Core Next 5th generation and was slated to be succeeded by the Navi architecture[9] in 2018, but in the new roadmap, changed to 2019. The lineup was released on the 14th of August 2017. It included the RX Vega 56 and the RX Vega 64, priced at $399 and $499 respectively.[10]

History[edit]

The Vega microarchitecture is AMD's high-end graphics cards line,[11] and is the successor to the R9 300 series enthusiast Fury products. Partial specifications of the architecture and Vega 10 GPU were announced with the Radeon Instinct MI25 in December 2016.[12] AMD later teased details of the Vega architecture.

Announcement[edit]

Vega was originally announced at AMD's CES 2017 presentation on January 5, 2017,[13] alongside the Zen line of CPUs.[14]

New features[edit]

Vega targets increased instructions per clock, higher clock speeds, and support for HBM2.[15][16][17]

AMD's Vega features new memory hierarchy with high-bandwidth cache and its controller

Support for HBM2 featuring double the bandwidth-per-pin over previous generation HBM. HBM2 allows for higher capacities with less than half the footprint of GDDR5 memory. Vega architecture is optimized for streaming very large datasets and can work with a variety of memory types with up to 512TB of virtual address space.

Primitive shader for improved geometry processing. Replaces vertex and geometry shaders in geometry processing pipelines with a more programmable single stage. The primitive shader stage is more efficient, introduces intelligent load balancing technologies and higher throughput.[18]

NCU: Next Compute Unit a Next-generation compute engine. The Vega GPU introduces the Next-Gen Compute Unit. Versatile architecture featuring flexible compute units that can natively process 8-bit, 16-bit, 32-bit or 64-bit operations in each clock cycle. And run at higher frequencies. Vega brings support for Rapid Packed Math, processing two half-precision (16-bit) in the same time as a single 32-bit floating-point operation. Up to 128 32-bit, 256 16-bit or 512 8-bit ops per clock are possible with the Vega architecture.[19]

Draw Stream Binning Rasterizer designed for higher performance and power efficiency. It allows for “fetch once, shade once” of pixels through the use of a smart on-chip bin cache and early culling of pixels invisible in a final scene.

Vega bumps Direct3D feature level support from 12_0 to 12_1.

Vega's rasteriser brings hardware-acceleration support for Rasterizer Ordered Views and Conservative Rasterisation Tier 3.[20]

  1. ^ The Radeon 100 Series has programmable pixel shaders, but do not fully comply with DirectX 8 or Pixel Shader 1.0. See article on R100's pixel shaders.
  2. ^ These series do not fully comply with OpenGL 2+ as the hardware does not support all types of non power of two (NPOT) textures.
  3. ^ OpenGL 4+ compliance requires supporting FP64 shaders and these are emulated on some TeraScale chips using 32-bit hardware.
  4. ^ a b The UVD and VCE were replaced by the Video Core Next (VCN) ASIC in the Raven Ridge APU implementation of Vega.
  5. ^ a b To play protected video content, it also requires card, operating system, driver, and application support. A compatible HDCP display is also needed for this. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.
  6. ^ More displays may be supported with native DisplayPort connections, or splitting the maximum resolution between multiple monitors with active converters.
  7. ^ a b DRM (Direct Rendering Manager) is a component of the Linux kernel. Support in this table refers to the most current version.
