Today at the opening of Computex 2019, AMD previewed the highly anticipated Navi family of gaming graphics cards. A series of new products received the marketing name Radeon RX 5000.
It is worth remembering that the question was one of the main intrigues when introducing Navi gaming options. Although AMD was originally supposed to use numbers from the 5000 series, the company ended up betting on the name Radeon RX 50. The idea behind the name is that it plays on the theme of the XNUMXth anniversary that AMD is celebrating this year.
In addition, another intriguing detail emerged. At the heart of the Radeon RX 5000 graphics cards is a new GPU architecture called Radeon DNA (RDNA), which is a further development of the Graphics Core Next (GCN) that appeared seven years ago.
The RDNA architecture appears to offer a new design for the GPU's base unit, the compute unit, resulting in improvements in power efficiency and performance per clock. In addition, AMD has implemented a new multi-level cache hierarchy in RDNA, which should reduce latency, increase throughput, and improve power consumption. The optimized RDNA graphics pipeline, meanwhile, allows the new graphics cards to run at higher clock speeds than before, and ultimately provide higher levels of performance. In addition, compared to chips with the GCN architecture, Navi has a more compact semiconductor chip size, but so far the manufacturer has not disclosed details by how much.
In sum, the RDNA architecture provides greater performance and lower latency with better economy. Compared to the Vega card architecture, AMD promised a 25% increase in specific performance per clock and a 50% increase in specific performance per watt.
As announced at the presentation, the first point of application of the new RDNA architecture will be the Radeon RX 5000 series of graphics cards, in which video cards called the Radeon RX 5700 will be the first to be released. The entire series will be based on Navi chips manufactured using the 7nm process technology at TSMC facilities.
A very remarkable feature of the representatives of the Radeon RX 5000 series will be their support for the PCI Express 4.0 bus. AMD is actively pushing the idea of ββmoving to a new version of the interface with increased bandwidth, and the Radeon RX 5000 will fit perfectly into the ecosystem offered by the company along with third-generation Ryzen processors and motherboards based on the X570 chipset.
In her speech, AMD CEO Lisa Su briefly demonstrated the performance of a gaming graphics card based on the Navi chip. The Radeon RX 5700 graphics card has been benchmarked against the NVIDIA GeForce RTX 2070 in Strange Brigade. At the same time, the expected novelty of AMD turned out to be about 10% faster.
AMD intends to start selling video cards Radeon RX 5700 in July, but a specific date has not yet been announced. However, AMD has promised to reveal more details about Navi's specs, pricing, and performance at the Next Horizon Gaming special event during E3 on June 10, 2019.
