How much perfomance increase for games to expect with new Ryzen+ (or Ryzen 2)?

[Rakanoth]

I have been reading about Ryzen CPUs coming in 2018. Some call them Ryzen 2 and some Ryzen+.

Considering the old performance leaps between previous generation AMDs (be it a large or small leap), how much performance increase can we expect in terms of gaming? 5%, 10%, 15%, 20% ... ?

I am asking this because I am not very much familiar with AMD's performance increases between "generations". It also depends on the architecture of course. Some architectures can facilitate huge performance increases, I guess. Is Ryzen one of those architectures that can possible provide a relatively large performance increase with the next generation?

Maybe need to rephrase: How promising is Ryzen 2 (or Ryzen+)?

There is alredy a thread about "Zen+" which is not the same as Zen2. Between process and tweaks I expect an increase around 10-20% better perfomance in Single Core.

Too soon to tell, or even estimate, I believe. I don't think any architectural details or "tweaks" have been released yet, nor have there been any benchmarks leaked. I don't even know if the chip has taped out yet.

Edit: But hopefully, we get an fmax increase.

Maybe 5% + whatever frequency bump they can achieve with the improved 14nm or 12nm whatever they going to call it.

Depends on how AMD Zen 1+ fixes CCX and memory latency. Since Zen 1+ is just a refinement, much of the same, I only expect a small improvement: < 5%

I fully expect Zen+ to be clocked higher, maybe 4.5-5ghz max OC, with no IPC increase. It should be very competitive assuming the new process allows Intel matching clock speeds.

Zen2 in 2019 could potentially bring some decent IPC bumps and better performance in gaming due to memory refinement.

My wild guess is around 10-15% if we are lucky. That would bring Zen to around 4.5ghz on a good day. It should perform similar to Broadwell-E in gaming at that point, maybe even a little better. That infinity fabric will still be working against Ryzen for gaming though. Its the same reason Skylake-X lacks a little grunt for gaming as well.

Zen 2 core (which should be Ryzen 3000) is hard to tell - it is 7nm, I'd say it could have 5-10 % IPC increase (not a ceiling, but let's expect conservative values). Frequencies who knows - could be +10-20% at start, unless the process turns out to be bad.

The "Zen+" (Ryzen 2000, coming in feb 2018 apparently) is probably just higher clocked Zen. There will be IPC increases only if some fixes/uncore tweaks get done, like higher memory support. However, if the chip is really 12nm and new masks/design were needed for it, some minor changes might in fact get made and perhaps could improve performance (but it won't be bigger than 5% difference if that even happens).

Basically, at this moment, only count on frequency increases.

[This is just my guess...] Probably 200 MHz ramp in max XFR single core boost (so to 4,3 GHz), or 300 MHz if they are lucky (4,4 GHz) and 300 MHz ramp in base clocks/all-core boosts. So possibly +300 MHz OC frequencies and when stock, ~9% improvement in multithread and ~ 5-7% improvement in single thread. If memory clocks increase, you get some effect on top from that.

Anything more will be bonus. It might be possible to get more frequency out of 12nm if it turns out to be good. But we don't know that yet.

Realistically, I only expect better memory controller and fine-tuned Infinity Fabric. That may yield 1 - 5% IPC increase. Coupled that with supposedly better process, we also will get 5-10% increase in base clock.
Anything better than what I've listed above, we'll get a winner.
