Have you got any source for Global foundries using a Samsung Zeppelin+ node? As not heard of them looking to license anything more from Samsung.Those who query about the Zen clocks.
There is a big article few pages back and I ill stay only on this.
The Samsung Zeppelin architecture used on the Zen, is designed to run optimal between 3.3-3.5. After that the curve of power to speed ratio gets high, and there is a cap with normal cooling at around 4-4.2Ghz.
However have faith. The new Samsung Zeppelin+ architecture, which is going into Zen+ is designed for much higher clocks and greater performance per clock at reduced power envelop also.
In addition, AMD has proven that the current Ryzen IPC is strong enough and beats the B-E IPC, while it overclocks at similar levels of performance.
Don't forget that, because while the prices are low that was the AMD target and has achieved it.
From the gazillion of 6900K, only the very best ones break the 4.2 mark with max speed the 4.4 for the second highest bracket. Hell many cannot go over 4Ghz without watercooling, while we have Ryzen at 3.9 with the stock Wraith spire air cooler!!!!!!!
Second is new architecture and personally love all the tweaking that is still unknown to us all. Now we understand that high speed and loose timings, is must for the Ryzen CPU. Because the Northbridge comms runs at 50% the RAM speed. And that affects the performance.
Something we need to take into consideration, that up to now both Intel and AMD cpus performance in relation to RAM, was pretty much stuck.
2400mhz was the point of diminishing returns, and was barely much gain using 3600Mhz ram against 2400Mhz Ram. But that has changed with Ryzen.
The higher the ram speed, the faster the system works. Imho we might see real perf when AMD and mobos update their BIOS to allow us even faster RAM as high as 4000Mhz (aka 4Ghz!),
I say interesting times ahead, especially for those of us who want to start tweaking and truly go back to proper "Overclocking".
(something applaud Nvidia with the Boost 3.0 curve, making overclocking on the Pascal cards really interesting).
I have enjoyed reading this thread, perhaps one day my motherboard will be here and I can test a few things for myself
Haha that is crazy, I'm waiting on a gigabyte k7. No estimate from OC yet but another retailer is expecting stock on the 24th which doesn't seem to promising.
