It's an update to Zen+, though a pretty big one. The last few "new" AMD designs were K10 in 2007, Bulldozer in 2011, Zen in 2017. Intel hasn't done a ground-up redesign in over a decade.
- amaranth 7y agoHaswell was a pretty major change though, even if it wasn't from scratch. If it ain't broke, don't fix it. Although with Meltdown and L1TF and ZombieLoad clearly, it is kind of broken...
- opencl 7y agoYeah there's not really a hard line between "improved version of old architecture" and "new architecture". Zen 2 seems to be about as big a change from Zen+ as Haswell was from Ivy Bridge. Ultimately what matters is how much they improved from the old versions. Supposedly Ice Lake is going to have 18% higher IPC than Skylake which seems like it will involve some pretty radical changes. Will certainly be interesting to see how that and Zen 3 turn out.
