AMD Ryzen 7-1800X Cracks 5.20 GHz OC with LN2 and All Eight Cores Enabled
AMD's upcoming Ryzen series processors promise to be an overclocker's treat. A PC enthusiast with access to a Ryzen 7-1800X sample managed to achieve an extreme overclock of 5.20 GHz with liquid-nitrogen cooling, and more importantly, not having to disable any cores to stabilize the OC. The 5201.07 MHz overclock, achieved by cranking the base-clock up to 137.78 MHz, and the multiplier up to 37.75X, backed by a core voltage of 1.875V, was even tested to be bench-stable, scoring 2,363 points in Cinebench R15. This also reveals that you should be able to finely crank up the base-clock multiplier in steps of 0.25X, (as opposed to 0.5X). The Ryzen 7-1800X will be available on the 2nd of March, 2017, priced at $499.

That said, this cinebench score is terrifyingly high.
Waiting for air cool numbers, especially on chips like the vanilla 1700
That said, 5.2 on LN2 seems kind of low, though it's "8 core - 16 thread bench stable" and not just "1 core CPU-z pic-with-a-camera stable".

BTW is that SHA a new instruction exclusive on AMD or Intel's gonna supports it too in future CPU?
Please correct me if i'm wrong but isn't it necessary to turn off HT in Intel's CPUs to achieve higher "all cores active" OCs, for benching purposes? IF this is the case, then this cinebench pic @btarunr posted is more impressive because it also shows that all 16 threads are active.

Please explain your reasoning.

Put differently? This shows how twisted this market has become.. he has one in his hands, all sorts of tests, comparisons, empirical observations he could have made/gone for. But what does he do, lol? He OCes it in LN2..
Normal, mature, 101% everyday ole use :(
Yes yes, i know, some of you are about to have an apoplexy, reading this. Still so though. As long as priorities are so twisted, as long as an entire market decides merely by watching numbers pass it by.. numbers it won't reach by the way..
Anyway. Looking forward to 'normal' tests. Just thinking of all the drama about to ensue if Ryzens are indeed -that- good makes me smile in anticipation, lol

AMD proc had 16t and did 2300 - not bad.
This means this March 2 launch isn't really for me, BUT will let me know the full capabilities of the Ryzen chips.
I do have quite a few concerns because i don't want to be forced to change to windows 10 and Ryzen may require it, and my OS is OEM, so changing motherboards may be a problem. Will see how the reviews pan out before i make my final decision.
It wouldn't surprise me if in a few months MS silently rolls out an 'update' that makes kaby Lake and ryzen systems running win 7 and 8 randomly start blue screening.
Just my two cents.
Since the overall trend is not going with previous "leaked" results (e.g. same performance at almost 20% lower clock), I can either assume that it was clocked higher, or something is amiss in this picture.
previously R7 1800x was just a tad faster than i7-6900K at slightly lower clocks(e.g. the same).
Or comparing to stock 1800X benches... a ~30% overclock with ~53% performance boost?.... in the real world it does not scale like that! You can't get more for less. Most official competitions, and even HWBot submission system still uses Win7 and below as a primary benching platforms. Most Win8/10 scores are considered valid, but are not accepted for any kind of competitive OC scoring (at least it was like that few months ago). The only thing I do not understand, is why there are still no submissions on HWBot or any kind of validation?
It's nice to yell in front of a camera, that "we broke the world record", but the truth of the day - there are no valid submissions, no screenshots, nothing...
if he's sponsored, he shouldnt be leaking real tests, you cant even be sure if amd isnt the one that approved the leak
i dont even care about water cooling, i'm into air overclocks for regular users... (but also find extreme ANYTHING, pushing any limits under or over, extreme sports, & so on to be interesting)
