It seems VIA's subsidary CenTaur
has been cooking up something new in the form of an Isaiah II architecture. Right now their company page links to a teaser site with a count down, set to run out on 31st Aug.
This has all come as a bit of a surprise as I haven't seen any new VIA CPUs for a long time, well since they released the VIA Nano (formerly code-named VIA Isaiah) in 2008. At the time the Nano was a competitive with Intel's Atom performing between 15 - 20 percent faster but not matching it in power efficiency. Linky
Unfortunately Via doesn't have the resources of Intel and wasn't able to make it a widely available success.
What's even more intriguing is that Extremetech
suggest the Isaiah II might be a hybrid x86/ARM processor. Chew on that.
