*Looks at Intel.
AMD being cautious makes sense it avoids lawsuits.
AMD has delayed the launch of its Ryzen 9000 desktop processors after discovering that production units initially shipped to channel partners weren't up to snuff. Out of an abundance of caution, AMD said it was holding back the official arrival of its six- and eight-core Ryzen 9600X and 9700X CPUs until August 8, and its 12- …
Watching Intel getting (rightly) raked over the coals for their quality issues, this seems like a no-brainer.
I don't think anyone will complain about the delay, and if they release a non-faulty (acceptably faulty?) line of processors after this then it just further draws favorable comparisons to Intel. This is a huge PR win for them as long as they don't mess it up.
AMD said it wasn't the silicon. Variable quality only affecting some could mean it's happening with chip assembly, the bits you see on the outside, wiring from the pins, IHS or the tiny capacitors around the chip. They've kept it mysterious.
Other chips (incl from Intel) have occasionally had problems with microcode to work around, change in voltage/frequency, repackaged.
My understanding is that first batch aren't hitting their expected out of box rated speeds and boosts... it could be as simple as boosting 100mhz lower... and from what I've read/seen they have a quick and easy test to check them over and can bin or ship them back to vendors... and if they bin them... they'll likely rebrand them as a lower tier later on.
Remember how all those 5800X3D CPU's that didn't quite meet the spec... were rebadged as 5600X3D ones as an exclusive for the US market.
If it's literally in the initial production run after they finalise and are no longer making engineering samples... and they've improved quality since then (happens all the time) and they're producing tens of thousands now as they ramp up production. Then replacing all of the first batch in a couple of weeks with current production makes sense.
The delay is for consumer parts, not channel partner parts... they're already shipping.
The expected consumer rush to buy the latest parts is going to be small in comparison to those channel partners... and could easily be covered in 2 weeks... especially with a staggered launch window now. 2 CPU's on the 8th and the other 2 a week later on the 15th.
