*** AMD "Zen" thread (inc AM4/APU discussion) ***

[CAT-THE-FIFTH]

It looks like Zen and Vega are moving to an improved GF 12NM next year:

Seeing how semiconductor companies are now using lower numbers to denote performance instead of actual size, I'm guessing this 12nm is actually just an improved version of their 14nm? They compared it to a competitor's 16nm instead of their first 14nm LPP...

Most likely but looking at the bumpf it should mean higher clockspeeds.

 

[DragonQ]

Yeah it's pretty much "14nm+".

Is that what was getting referred to as Vega and Ryzen+

Very Interesting. 15% smaller and 10% more performance in 2018. I think these will be a huge hit.

 

[HeX]

Indeed, if these can reliably hit 4.2+ the single threaded Intel gap closes even more.

 

[jigger]

Well at a 10% increased clock speed on just a straight 1 to 1 shrink that will be mid 4Ghz.

Especially if they can improve the IMC a little bit as well.

 

[jigger]

AMD should probably rename this chip. A 10% jump is about 5-6x what Intel offer. Skylake, Kaby and it seems coffewake managed 1%

 

[chroniclard]

Improvements with drop in replacement CPU's, yes please.

 

[HeX]

Well at a 10% increased clock speed on just a straight 1 to 1 shrink that will be mid 4Ghz.

I was basing on the fact that 3.9GHz all-core seems to be the most common overclock for gen1 Ryzens, 10% on top of that would be 4.29GHz, so if the majority could hit a reliable 4.2+ that's a decent improvement, and totally reasonable taking that those top slice Threadrippers are commonly hitting 4.1+ on the current fab.

 

[opethdisciple]

Yea. This was one of the reasons I went AM4. I'll upgrade the 1700 with the last AM4 compatible chip in a couple of years.

Probably only then need to add another 16Gb of ram and sorted for another 3-4 years. (GPU upgrade permitting)

I'm hoping by that time we have AM4 compatible chips greater than 8core /16thread.

 

[Jokester]

Aye, hoping to get 10 years of decent performance out of it with one of the later CPUs being dropped in there.

Well the XFR chips are 4-4.1Ghz stock.

 

[Orcvader]

Well the XFR chips are 4-4.1Ghz stock.

That's on only a couple of cores, not all of them. When all cores are under load it can't sustain the high speed very well.

 

[jigger]

Any core can run those types of speeds though.

 

[HeX]

Any core can run those types of speeds though.

At very high volts well outside of the efficiency range of the fab process yeah. No doubt everyone could get 4GHz if you were willing to pump the XFR 1.5V+ through your CPU constantly. Realistic all core speeds are 3.9 at reasonable volts. With the fab update that all core speed should shuffle up a few notches while remaining in the 'reasonable' voltage range.

 

[Orcvader]

Any core can run those types of speeds though.

Takes a lot of volts for it to though .

 

[jigger]

Takes a lot of volts for it to though .

Any one core can hit 4.1Ghz at stock volts with XFR. But yeah with performance comes power use. No getting around that.
