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

I'd ignore test, 1700, base is 3.0GHz, turbo is 3.7GHz, AMD do this so it qualify as 65W part. If you switch it over to manual mode in a good motherboard like Crosshair you just lock it to run at 4GHz all the time, then the performance is vastly better, even beats 1800X.

The issue is how far the 1800X can clock. The AMD CPU overclock software has max speed somewhere around 6.3Ghz..... which I guess that's LN2 territory.... but what it can under water? 4.5?

And until reviews come out, holding off even if part of me want to buy the Asus Crosshair, the1800X and everything else I need for the custom WC of the system.

I think you just convinced me to downgrade the 1700x to the 1700 XD

What are you upgrading from Kieran?

Can you give us a hint about how far the chips will oc? Just wink if they can manage 4.5Ghz on water.

He already said that. They managed to overclock the 1700 to 4-4.1 on high end motherboard using 240mm AIO.

1800X does 4.1 with XFR alone. Who knows about manual, other than the 5.2Ghz under LN2 of the F1 stepping chip (last test samples had F4 stepping) we don't know much until March 2nd

Where? Must have missed it.

Its why we need to see how the R7 1800X performs as it is less TDP constrained.

Its also why the 4C and 6C models might even be better - they will have far more TDP available per core to hit higher clockspeeds. If the 8C models are even remotely competitive,it really is a good indication where the lower end SKUs will land.

But as Gibbo said setting it to manual and you can run 4ghz all the time. So by proxy it would disable that TDP limitation.

Mins are bad, hopefully that is just an anomoly in that specific game, cause no amount of overclocking is going to catch that up.

that is still 3.4 Ghz 1700 Vs 4.2Ghz and 5Ghz 7700

That does hint the 8C are TDP limited which might explain XFR being there so the CPUs can go past the TDP limit.

Agree ...will also be interesting if disabling some cores on the 8c will give higher clocks ......

Yeah,but plenty of test sites are going to test these stock for stock too,so its only far if we compare the 91W TDP Core i7 7700K and 100W+ TDP Core i7 6900K against the 95W TDP R7 1800X too.

first i wanted a 1800X, then i decided to go with 1700X, but now because of you im considering 1700

 

[Spyhop]

That makes me feel good about this £155 Asus mobo preorder... that it's not good enough for 4GHz OC

 

[CAT-THE-FIFTH]

Well the R5 1600X is 3.6GHZ to 4.0GHZ at the same TDP as the R7 1800X,and has XFR which the R7 1700 lacks.

 

[awaybreaktoday]

So what does the X stand for, from my understanding there is still an NDA on what the X fully means.....

in your opinion, do you think the MSI Carbon is capable of getting it up near 4GHz?

I saw this on AT forums:

Apparently it is a R7 1700X tested in GTA V.

 

[CAT-THE-FIFTH]

The hype tram is too much now - I will be glad when the reviews drop so we get to see how it performs!!
