At AMD's Capsaicin & Cream event at the Game Developers Conference 2017, the company unveiled that their next-generation line of graphics cards will officially be called Radeon RX Vega. Presumably each Vega model will come with some additional numbers and letters to denote how powerful it is.
If you were expecting any other news about Vega at the event, you'll be disappointed to hear that this is basically all AMD announced. Most of the information AMD 'revealed' at the event about Vega we already reported on back in January.
There were two small tidbits of additional information though, as spotted by The Tech Report. AMD demonstrated how Vega's High-Bandwidth Cache Controller improves performance in real-world games: it doubled the minimum framerate in Deus Ex: Mankind Divided compared to a "traditional VRAM mode".
AMD also showed how Vega's increased FP16 capabilities - double the throughput of FP32 - allow the GPU to render twice as many hair strands in a particular scene.
For more information on Vega, you'll have to wait until closer to its launch. At this stage we expect AMD to properly introduce Vega around Computex in the middle of the year, which would just scrape inside AMD's stated first half of 2017 launch window.
