Remember the part where I said:
you might have noted that 10000MHz effective was the baseline for GDDR5X for standardization (timings and latency) for a catalogue product, but the company had pushed the same 20nm silicon to 13000MHz effective during testing.
At this point I'm not even going to go through my old posts to find the links or the press deck, because as you've amply demonstrated - like your claims of Pascal requiring LN2 to reach 2.1GHz (when the sample shown was just picked at random
from a number of Maingear systems running demos) that when shown to be wrong, you just move onto trolling another facet of non-AMD graphics - usually as equally uninformed as the previous attempts.
I made you a wager regarding whether Pascal would require LN2 cooling to reach 2.1GHz as per your assertion
...you quickly skulked off and left the thread.
I'll make the same offer regarding GDDR5X overclocking. If GDDR5X overclocking is a bust, I donate. If it overclocks as a percentage over stock as well as GDDR5, you donate.
I'm guessing you just like to put the FUD out there, but have zero confidence in what you are spouting.
You really should just migrate to wccftech. 90% of the people there just troll for the enjoyment, and 89% of them don't question because they don't follow tech past the headlines either. You'd really fit in seamlessly.
