To complicate matters, it all depends on the type of RAM your cards have too, which is luck of the draw when you buy them.
You'll get Hynix (best) 30-31Mh/s, Samsung (ok) 28-29Mh/s, or Micron (sucks) 28-29 Mh/s.
Is that the general expectation these days?
I always thought that if I got Samsung VRAM I was going to be able to do more. Hynix (formerly HYumdai electroNIX) is better?
I know that Elpida (now defunct, but owned by the generally accepted last place Micron), although some cards made 5 years ago have it, or does that brand live on, made by Micron?
I know that much of it is subjective, absent concrete measurements & data. My 6gb (Gigabyte) 1060 with Hynix is not keeping up with what the 3gb generic/HP 1060 which had Samsung memory.
I could OC the Samsung to +280 stable, but the Hynix has to be dialed back to +200 even though it will run with +240. I prefer to be able to leave my rig running for the week/end as opposed to having to constantly monitor from remote.
