How are both cards performing when overclocked at the same frequency? I haven`t found any recent articles or threads comparing the two when both are OCed.
Somebody stated the following (april 2012):
Stock speeds
Stock 7870 = 1000/4800
Stock 7850 = 860/4800
difference = ~20%
with GPU Tweak unlocked overclocks
OC 7870 = ~1250/5600
OC 7850 = ~1250/5600
difference = 6-8%
Is this true? Does the gap closes when they`re clocked the same?
I can`t reach 1250mhz with my 7850, i can get a stable 1150/6000@1.18V or 1200/5000@1.22V in benchmarks and games.
Is there a small or significant improvement for a 7870@1150mhz over a 7850@1150mhz?
I mostly play titles such as Fallout New Vegas or Skyrim, both heavily modded (2K textures + ENB). Right now i get ~40fps in Skyrim with my 7850@1150mhz at 1280x1024 resolution. I want to upgrade to a Full HD display so i`m expecting further fps drops. Would a 7870 do any better? How much would the frames drop from 1280x1024 to 1920x1080?
My specs: 2500K@stock, 8GB, MSI 7850 2GB Twin Frozr III
Thanks!
