FUD Zilla heard from its sources, which prefer to remain anonymous, that there's no 7nm Vega gaming GPU on AMD's roadmap. At investor/press events, AMD presented the 7nm Vega as an artificial intelligence product and it appears this will be the sole target market of this product:
Unfortunately, there is no Vega 7 nm GPU on AMD’s gaming GPU roadmap right, now nor is it planned. Nvidia is expected to launch its Turing GPU later this year, probably for "back to school" or the holiday season and the performance gap will further increase. We had this confirmed from multiple sources close to the matter.
Basically, this implies the next big gaming GPU launch from AMD will be the 7nm Navi lineup sometime in 2019. FUD Zilla speculates AMD isn't making a 7nm Vega gaming GPU because it would be too pricey to be competitive.
The site claims Turing will be the successor to NVIDIA's Pascal, these new gaming GPUs are anticipated before this year's back-to-school season.
