Computex 2019 | AMD previews new Navi graphics architecture
Navi will power a lot of midrange graphics cards in consoles (next-generation PlayStation), desktops and laptops. Navi features a new microarchitecture called RDNA (Radeon DNA) that is a complete redesign and not just a small update from GCN. The three new key features of the graphics solution are:
- New compute unit design: Improved efficiency and increased IPC
- Multi-level cache hierarchy: Reduced latency, higher bandwidth and lower power
- Streamlined graphics pipeline: Optimized for performance and high clock speed
Compared to the previous Vega architecture, Navi should offer 1.25x performance per clock and 1.5x performance per Watt. Instead of the fast and expensive HBM graphics memory, Navi (on desktop computers at least) will use cheaper GDDR6 chips.
Navi will launch the first desktop graphics card of the RX 5000 / 5700 series (named after AMD's 50th anniversary) in July. A first benchmark shows an unnamed RX 5000-series card performing against an RTX 2070 desktop GPU in the Strange Brigade benchmarks, which it could beat by 20% according to AMD. Therefore, we expect the fastest RX 5000-series GPU to be at the level of Nvidia's GeForce RTX 2070.
More information on the RX 5700 series (models, prices, and performance) will be shown during the E3 livestream on June 10, 2019, 3 PM PST.
