You got that link from another thread in the overclock forum. The calculator on that site is flawed and does not subtract overhead correctly.

This is the correct calculation minus overhead (well within the DP 1.3 bandwidth specification):

Whatever. They both lie. Feel better? Regardless, I'm right and that is that. Stop being an AMD fanboy and just deal with reality for once. And no, that cable will not fully support all DP 1.3 functions. Signal degradation will kick into full effect. You can buy it though if that makes you feel better tongue.gif

Either Way, it's simply OCd at the end of the day. If it was 100hz, period. Then yea that's something but both require OC so I'm not seeing a major reason to wait.

You're simply not right. We will get a DP 1.3 with next gen cards. It is a fact. Also, that cable will support DP 1.3 if it says it supports it, just like it supports DP 1.2 when it says so.

How did you manage to pull out of somewhere I was "an AMD fanboy"?

With these places carrying such limited stock, for those that are playing lotto with thr x34 how long have you waited at times for your replacement?

Yup, but don't you add overhead? Or is this a technical overhead, not layman's "overhead"

Like: If "X" = monitor output (pixel density, bit rate, refresh rate etc. etc.) then:

32.4Gbp >= X + overhead

else your connection isn't good enough.

Not that I'm doubting you, just trying to figure out where I'm derping at in my understanding.

DP 1.3 is not even that good, the best we can get is 5120x2160, 21.9, Gsync and 95hz, we cannot even get 100hz on DP 1.3 with 4K 21.9, so really DP 1.3 is not enough

Just found this "Allowing for data coding overhead, this provides a total data transport capacity of 25.92 Gbps or 3240Mbytes/sec."

So really only 5120x2160 75hz is possible, so DP 1.3 is awful (if that is correct)
