There are already G4XEs out there.
Undoubtedly, but more and more it appears from the various websites
and MLs that the Articia-S is still too buggy to let the G4 perform
optimally. Which makes Genesi's decision very plausible. If they had
to design, produce and mount a new April-2/3 for the newer Articia's
also, it's better to change for a new, bug-free chip.
As soon as someone does have an Amiga-One-G4, could (s)he please post
some real-life values of its performance? At ANN.lu for example
someone claims the L2-cache wouldn't work with the G4 and the current
Articia on the AmigaOne, only with the G3.
