Most recent example is Kaveri Refresh.
See answer by AtenRa. Also, when was the last time Intel released a new CPU on schedule? If anything they have been plagued by delays the last few years, and it continues with Cannonlake and 10 nm.
2012 Trinity
2013 Kabini
2014 with Kaveri
They aren't, which can be a huge problem (for GF and their customers).
Cut and paste would require "copy exact", which is more costly in terms of equipment costs than what GF is attempting.
GF wants to recycle as much of their existing equipment from prior nodes as possible, purely for cost savings (penny wise, pound foolish) which has resulted in them cobbling together something that is similar to Samsung's process ("electrically equivalent" is the vernacular we use) but the pain comes in terms of process variability (parametric yield loss) and defectivity (functional yield loss).
On the flipside though, it is GF's only hope for a future, so eventually they have to get it right or they risk becoming the next Jazz or Tower.
Any insight into whether the DigiTimes report re: GloFo's 14nm yields is true? Thanks!
You're getting defensive again. AMD's release schedule has nothing to do with Intel.
Fixed that for you. Trinity was supposed to be a 2Q2012 product, but didn't ship until October.
Wow, that is a total lack of foresight on AMD and GF for allowing this to happen. Intel generated 13 billion in sales last quarter. If AMD has a competitive product that can recapture even a small portion of that market share, they are losing billions for every quarter they delay.
Is that a new CPU, or a respin of an existing CPU?
As far as i know, GloFo is already producing 14nm LPE wafers in Fab 8 at New York.
What AMD will use for ZEN and any other 14nm products is the 14nm LPP in Fab 1 in Dresden Germany. The 14nm LPP was originally scheduled for late 2015 early 2016 production.
But, ZEN is not the only product for 2016 and we may see 14nm products before ZEN release.
It's a respin with a new stepping. But you asked about when they met their launch date, and they met it, at least with the 7870k anyway.
The 870k, despite having been announced already, is not available for purchase. They may have the 880k out by the time they actually start selling the 870k.
No, I asked when they met their date with a new CPU, not a stepping and a speed bump.
. . . so now there's a difference between a new stepping plus a speed bump and a new CPU? Gotcha.
Good
Supposedly Bristol Ridge could enter on 14 nm instead on 28 nm.. But that seems to be discarded... So AMD will hardly have some performance increase.So will Bristol Ridge count as a new CPU? It's 4 Excavator cores with 512 GCN 1.2 shaders on AM4, and at this rate, AMD might have to launch it and AM4 early to cope with Zen delays. But, you know, we can't give them any credit for launching it on time (or early), since it's just Carrizo in a new package and (probably) without HDL libraries. Right?
Or am I missing something here?

Since we're discussing what Intel CPUs that AMD Zen will compete with, I think it does.
14 nm and using Carrizo improvements... Seems Phenom II all over again.die shrink with same uarch i think is a new CPU. especially with regular rather than HD libraries.
sounds like AMD's kabylake.
No insight as to whether or not GF's 14nm yield is the specific cause of a delay on AMD's part to get Zen off the ground...yes their yields are craptastic but the timeline involved here is nearly 1.5 years out, which makes me suspect the yield argument is a red herring.
What I would be more apt to believe is that AMD has so woefully underfunded the R&D for Zen such that the tapeout date has now been pushed out far enough so as to make a Q4'16 ship date virtually impossible to hit (regardless of yields).
But it is a lot easier to blame the foundry because the foundry can't come back and make a rebuttal to the contrary, bad for business to show-up the customer.
But Sandy Bridge and Sandy Bridge-E were released 4 years ago, so the timing of their release dates vs. projections is somewhat irrelevant at this point.

A few weeks ago I found an AMD'ers LinkedIn profile mentioning, that he works on the next gen x86 arch to arrive in 2017.
Edit:
The exact wording:
System Architect for Carrizo APU (launched in 2015) and AMD's next-generation (to be launched in 2017) mainstream mobile/desktop FX and A-series APU.
If you are using duct tape, clamps and cardboard to align your equipment 1.5 years is not a long time ;-) There's a reason Intel spends so much on R&D and equipment doing it right costs a crap ton of money.
