Does a 5970 OC match the performance of a 5870CF? - Page 2

Mostly that's due to heat problems. The 5970 was manufactured to be able to take voltage increments via software (i.e. XFX Over Volt Utility) so you can push past 900MHz Core/ 1300MHz Memory. It's only for benching those figures though, running 5870 speeds constantly is do-able, but the FPS gain isn't that significant. You still have 2 5870's on a stick, same shader count and everything, just running slightly slower to sit under the 300W max TDP allowed for PCI-E Certification.

They are the same thing.

Of course they will match.

Most I ever got was 960/1275 on the 5970 and 1050/1275 on the 5870s on air. Just havent pushed any further bc of my trifire.

My XFX can do single benchruns at 1040/1325, but i normally run it at 980/1325 no problem, for benchies ofc. "stock speeds" 900/1200 1.2v.

Still a great card imo.

and yes it matches the performance of two 5870's
