AMD launches the RX 5000 series graphics card with 7nm Navi GPUs




AMD has plagued its next generation graphics card using the Navi GPU as the RX 5000 series, which provides performance and power enhancements over the Graphics Core Next offers, with the first RX 5700 card within range to arrive in July.

Reported on Computex on Monday under AMD's keynote, the RX 5000 series uses a new architecture called Radeon DNA (RDNA), which will be used with the more established Graphics Core Next architecture. As part of the architecture change, the new GPU called Navi will be used, which is said to offer significant improvements over its predecessors.

The Navi Compute units have been refined from the versions used for Vega to make each individual as effective as possible. In theory, a Navi calculator will be 25% faster than a Vega equivalent per clock, with a 50% improvement per watt current being used, partly due to AMD's switch to using the TSMC's 7-nanometer production process.

At the same time, AMD has performed more refinement of its graphics pipeline to handle high clock speeds while presenting a multi-level cache to minimize bottlenecks.

To follow the new architecture, AMD also adds support for GDDR6 memory to the platform, and further improves the memory bandwidth than that offered by GDDR5-based cards. Finally, GPU supports PCIe 4.0, which promises increased bandwidth on systems that support that connection.

AMD's first card with the Navi GPU will be the RX 5700, which it will launch in July. Details of the card were not informed, but more information will apparently be offered under E3 on 10 June.

While AMD is one of the two largest companies in the graphics card industry worth seeing, it's basically the only interest for Mac users. Modern Nvidia GPUs cannot be used on macOS without any significant effort, as Apple has decided not to approve Nvidia's drivers, and makes AMD cards the default option.
