Radeon RX 7000 series
Architecture and Features
The Radeon RX 7000 series is based on the RDNA 3 architecture, which provides several key improvements over the previous RDNA 2 architecture. The RDNA 3 architecture features a dual-issue shader ALU, which allows for the execution of two instructions per cycle. This results in improved performance and increased efficiency. The series also includes a second-generation Ray tracing accelerator, which provides enhanced support for real-time Ray tracing and other advanced graphics features. The Radeon RX 7000 series supports up to 96 Compute Units (CU), each with 64 stream processors, resulting in a total of 6144 stream processors. The Radeon RX 7000 series also features a range of other innovations, including a chiplet design, a second-generation Infinity Cache, and support for AV1 hardware encoding and decoding. The series also includes a new "Radiance Display" Engine, which provides support for DisplayPort 2.1 and HDMI 2.1a, as well as 12-bit color and Rec. 2020 support for HDR.Specifications
