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.

Well with 10% more performance that 4Ghz would be 4.4Ghz at 1.5v or probably a little less from using 15% smaller transistors. Will be interesting to see.

Voltage aside, say we get to 4.5Ghz as a common overclock on this new process. Is that going to actually bring scaled performance, or is there a limitation somewhere else in the CPU/system that means increasing CPU frequency has diminishing returns?

Does 4.2 GHz actually make a big difference in framerates for games compared to 3.9/4.0 ?

Support for faster ram will be where the performance gain is. Same as it currently is with Ryzen.

Thats a good question. Has 8 pack done any hard-core overclocking with Ryzen. He would probably know the weak points better than most people. I seem to remember someone taking some world records with Ryzen.

I don't focus too much on gaming performance too past can the CPU make 100FPS as most of the time the performance is dependent on the graphics card.

In certain scenarios it will be IF holding it back, so a better memory controller that can support higher speeds alone will benefit Ryzen greatly. If they can make at least 3200 the officially supported speed then it shouldn't hold Ryzen back too much when it's clocked higher. Or even better, get IF to be linked to the CPU speed instead of the RAM speed if possible.

The infinity fabric is definitely the crux of Ryzen, if they actually make Zen+ or Zen 2 a real 8 core instead of 2x 4 core modules on the same die, they'll probably reap some decent performance gains just from that.

The cost of Ryzen is due to this design, and enabled them to be competitive again. I don't think it is going to be changing any time soon.

It definitely did, but they went with the dual module design most likely to easily accommodate an iGPU instead of 1 module for their APUs. If they get some more revenue they will probably be able to afford more specialized dies.
If they don't then Cannonlake/Icelake are going to leapfrog them.

You need a system to talk to the cores. Swapping to a ring bus or HT system will just reduce the scalability, up power use and reduce clock speed.

Moving away from a coherent fabric would mean talking to cores over an external bus and at that point you're slower and suffer more latency.

What you're describing is X99.

Just having look at some BIOS update notes and seen a 3033Mhz memory profile. Anybody running 3033Mhz with Hynix?

Yes is the answer to your question. In fact running 3200 with 4 sticks of ram and have been since bios 9945. Just don't use the memory profile's, set the profile option to Manual and then set your ram manually.

Cheers. So Ryzen is looking good with Hynix now.

Yes. Regardless of what anyone on here has posted negatively about Hynix, it has been more than capable of running at 3200 since at least the 9945 bios on the ch6.

Bit of a blanket statement. There are plenty that cannot. I have some corsair hynix led 3200 that cannot go above 2933, bdie on same cpu and board can do 3466.
You may be one of the lucky ones.
