Vega

Vega, also known as RX Vega, is a microarchitecture for GPUs (graphics processing unit) and APUs manufactured by AMD. It is the fifth generation of AMD's GCN (Graphics Core Next) microarchitecture.

Vega features

• Support for HBM2 (second-generation High Bandwidth Memory), a stacked memory technology similar to 3D XPoint. HBM2 can double the bandwidth per pin of first-generation HBM.
• NGU (Next-Gen Compute Unit), a processor capable of performing multiple logical operations on data of varying bit lengths in a single clock cycle. For example, the processor can perform 512 8-bit operations, 256 16-bit, 128 32-bit, or 64 64-bit operations in a clock cycle, depending on the needs of the application.
• "Primitive shader" technology, a programmable single-stage geometry shader that is more efficient than traditional multi-stage shader pipelines.
• Manufactured using a 14 nm fabrication process, which results in faster processing speeds and greater energy efficiency.

Announcements and releases

Vega was announced on January 5, 2017. The first Vega GPUs, the Radeon RX Vega⁵⁶ and RX Vega⁶⁴, were launched in August 2017.

In June 2018, AMD announced the Vega Instinct, the first GPU manufactured with a 7 nm fabrication process.
