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

[Orangey]

Only 8 coars?

Need moar.

BTW it's being reported that 14nm LPP will be certified Q3 and in volume Q1. Still no sign of anything useful.

 

[humbug]

will be interesting to see a true 8 core chip up against a 4+4HT chip as well on DX12, not that i think its going to make much difference but you never know.

Anyhow, looks like im sticking with my 4770k until Zen and then its back to AMD for me if the Zen is anywhere near the Haswells performance

At the moment it looks like this.

DX12 Draw Calls.

Score: 22,198,217. 4790k @4.8Ghz

Score: 14,970,812. FX-9590 @ 4.7Ghz


DX11

Score: 1,233,983. 4790k @4.8Ghz

Score: 881,618. FX-9590 @ 4.7Ghz

The gains are worse for AMD.

FX and APU replacements on FM3 platform in 2016.

Edit!!

Looks like CPUs and APUs too. So the "high performance" parts will have no IGP it appears.

Links not working for me, did anybody save it or got another linky?

Think Anandtech forums are down.

4-core APUs and 8-core CPUs are scheduled for 2016. The low power "Cat" cores are being replaced by Zen in 2016 too.

 

[humbug]

Yeah.

4790K = 18.5x Gain

Vishera = 17x Gain


4790K: 4 Cores 8 Threads, the extra hyper threads pile on that little bit more than just the 4 main threads alone

Vishera is still treated as a 4 Core 4 thread CPU. Compilers are not designed with Vishera in mind.

Three segments for desktop.

High performance - FX succeeded by CPU with upto 8 Zen core.

APU - SR succeeded by APU with upto 4 Zen cores.

Low power offering with 4 Puma cores - suceeded by new CPU with two Zen cores.

High performance desktop and APU unified by new FM3 platform.

I saved the desktop slide

< November 2016?

I would say later 2016 is when I would expect to see them IMHO. It all depends on how well the process nodes AMD is hoping to use pan out. They are constrained by their fab partners too.

Edit!!

Thanks,Orangey!

High performance - FX succeeded by CPU with upto 8 Zen core.

APU - SR succeeded by APU with upto 4 Zen cores.

Low power ARM offering with 4 A57 cores - suceeded by new CPU with two K12 cores.

High performance desktop and APU unified by new FM3 platform.

So the are going all for one doing away with separate APU and CPU platforms.

Makes sense if you have an APU and want to upgrade to something big and fat.

Yep.

just what i want now not in 2016

Sadly,AMD is also constrained by when Samsung,GF and TSMC can start producing large 14NM chips in volume too at a viable cost.

The gains are worse for AMD.

Intel: 1698% increase
AMD: 1598% increase

Its not TOO much of a difference really when you consider the overall increase. Only a 6.25% bonus for Intel. When you consider the architecture of piledriver difference, pretty negligible.

LOL, the most pessimistic reading of those numbers.

Seems to me that if Intel presently have an advantage in games with 1.2 vs 0.9 (Munits?), then that advantage will utterly vanish when they're posting 22 vs 15. Mantle might well turn out to be genius for forcing this hand.

(Assuming draw calls is a bottleneck.)

And don't forget that a 6.25% performance advantage for Intel will probably translate to at least a 25% price premium for Intel haha.

It wasn't really pessimism, rather a factual observation

I'm holding a lot of optimism for Zen.
I'm contemplating not buying into X99, just to wait and see if Zen can deliver me something over my 4770K.

All the learned analysts who have read the leaks seem to think Zen will still be slower than Haswell. You can get your credit card out now.

Slower core for core, or slower overall?
