Mate, I just grabbed a test, looked at the bench results for most of em and posted it. I didn't even check them all and was just proving a point.
iirc, you had a 1080? So you went from a 1080 that beat a Vega 64 in most games, went to a 1080Ti that comfortably beat the Vega 64 in ALL games and then went to a Vega 64 that needs volt adjustment to be comparable with your original card. That seems madness to me but hey, I am old and just like gaming in my downtime.
Yes.
I had the GTX1080 oced at 2190 (spent hours trying to see how the curve works).
Then moved to 1080Ti (post Vega 64 launch) which on air couldn't do more than 2163 and the factory overclock was 2100. And said many times even last few weeks, that anyone who considers a 1080Ti should get it.
(and anyone gets the Aorus ones should upgrade to F3F/F4 bios as it greatly improves the card).
And then moved to Vega 64. True is slower than the Ti and said so numerous times, but not the 1080 though. Not from my experience on the games I am playing. (even Nvidia favoured titles like WOT & WOWarships).
However last 4 months was the most fun I had with a card tweaking the last 16 years. (since 9500np)
And you will see it on my activity. I have posted a single benchmark in here when I had the 1080ti and only couple when I had the 1080.
I wasn't even active assisting people with tweaking and improving their perf because they are boring cards to tweak and overclock. You just crank 2 sliders and off you go.
Though see how many posts on tweaking the Vega I have done and the results we are geting on benchmarks (mid 27000 on graphic, the best 1080 does 25000 if the room is cold....).
Also another two reasons moving to V64 was that I still have freesync monitor and had I bought the LG32GK850G back in March wouldn't have upgraded from the Ti. (wrote this also numerous times).
And lastly, I am playing with TensorFlow since June. The GTX1080Ti is a slow card compared to Vega 64. Especially undervolted and HBM to 1100, is amazing card close to TV100 performance. A card 20 times more expensive.
So is not only "more" FPS.
