Towards the end of 2016, French publication Canard PC reported that AMD may have been planning hexa-core Ryzen processors for a 2017 launch. Now, Thai website Zolkorn is refuting these claims saying that AMD will not be releasing any hexa-core Ryzen CPUs for the mainstream market. Instead, AMD will be launching quad-core and octa-core variants without the equivalent Hyper-Threading technology in its place.
Furthermore, the previously known SR3, SR5, and SR7 model abbreviations are believed to be referring to entry-level quad-core CPUs with Hyper-Threading, mainstream octa-core CPUs without Hyper-Threading, and enthusiast-level octa-core CPUs with Hyper-Threading, respectively. These are still rumors for now and continue to be just speculation based on the single source.
AMD is hoping to make a comeback in the desktop space with the upcoming launch of Ryzen and the overarching Zen architecture. Leaked benchmarks show a supposedly high-end Ryzen CPU rivaling the expensive Core i7-6800K. The new Zen and Vega announcements should give AMD the performance boosts it needs in the processor and GPU markets against Intel and Nvidia, respectively.
