It's merely a tweet with no source, however, Tum Apisak once again threw some interesting information online. This round it's AMD in the spitlight, who seems to be working on two new Athlon processors. Of course, the Athlon procs are APUs, but the names would be Athlon 300GE and Athlon 320GE.
In his tweet he mentions that the Athlon 300GE would get a clock frequency at 3.4 GHz where the Athlon 320GE would do 3.5 GHz. The clocks would be really close to what they were for the 200Ge series. It is assumed that the underlying microarchitecture used for the 300GE and 320GE is Zen+. What would differentiate the APUs would be a stronger VEGA IGP based on Vega 9, but that last bit is a rumor.
