Didnt we get somewhere that ALL SKUs will be unlocked and oc'able?
From an enthusiast standpoint that would argue to get the LP and overclock-away.

Yeah, it would make most sense to do maybe 5 models tops. Two 8 cores, a 6 and two four.

Yes, all are OCble. But, how far they OC will depend on the bin, which is why I propose only 3 bins rather than 5 or 6.

As you and others point out, it may not even be 3 bins. I guess that will depend on what variability of performance across the wafer AMD are seeing.

I have never quite understood the binning process exempt maybe from the very early stages of a new node when everything is still getting sorted at the fab.. we have plenty of history with 'lesser skus' clocking 50%+ right past flagships and hitting same OC territory as said flagships.. Maybe things have changed I dont know.

Clocking right past flagships at what TDP?

For instance, with XFR, a very easy way of AMD to differentiate between Black Edition Ryzen and Standard Edition Ryzen would be to allow the user of BE chips to OC beyond the manufacturer set TDP.

Wouldn't that make them kind of 'locked'?

What are the chances to see Zen (or Zen+/++) on 12nm FDX in 2-3 years? What changes are needed to use different process for this chip?
Papermaster said tock tock tock for zen.
Amd have limited resources so i understand it as proces and arch change at the same time?

The wsa makes it possible for the to pay gf if they use tsmc and it runs to 2020 in the existing form. Here it will be negotiated, probably in a ugly streetfight , and last till 2024 when it ends.

Now tsmc have 15 to 20 7nm tapeouts this year. I would be very surpriced if amd didnt negotiate the wsa to not get the oportunity to use such a low power process for a high margin server cpu like zen. Then keep the cheaper lower margin apu stuff on gf together with low and midrange gpu.

What should 12fdx be used for have you imagined?

Seems the way to accomplish any TDP limited scenario would be in the motherboard, by limiting voltage.

When asked how long Zen would last, compared to Intel’s two-year tick-tock cadence, Papermaster confirmed the four-year lifespan and tapped the table in front of him: “We’re not going tick-tock,” he said. “Zen is going to be tock, tock, tock.”


It's called marketing. What he says is irrelevant, it doesn't tell us anything.

In that case we may have BE without voltage limit and standard edition with a voltage limit. But that would mean that base clocks would mean nothing and only the frequency the processor can reach on the limiting voltage would matter.

They might not need to lock any of them, just bin them for leakage and speed, and only make their top chipsets voltage adjustable.

yeah right. Nothing what the AMD CTO says is relevant just what a random guy on the internet like you says is true. correct. I don't see why AMD cannot make significant architectural improvements on a yearly basis. AMD has already done it in the past with Bulldozer -> Piledriver -> Steamroller -> Excavator . The problem was Bulldozer was a horrible design.

Something keeps nagging at my brain here, folks:

If you're AMD, why limit this upcoming octacore chip to 95 paltry watts?
Why not up the tdp to 110w - 120w and take the fight to BDW-E across the board, out of the gates? OR maybe that's what XFR is for - clocking chips up to 160w under turbo?

AMD has been pushing performance per watt a lot lately.

+1. You have to wonder. They only scenario I can come up with is that this is a server chip and when AMD was taking notes on the wishlist from the potential client pool, perf/watt came up. We have to face that *we* are not the target audience, we just get the scraps.

Not that I think this is the case but remember how Fury was awesome right up to a certain wattage? I wonder...

We know there are 3.6//4.0ghz 95 tdp ES's. People dont need to invent anything. I dont know why people AMD is going to show there hand 1 and a bit months before launch!

Remember the last time AMD had a massively performant product , when did we find out what RV770 looked like? The DAY of launch.
