All 7950s can do 1 GHz but probably not all of them can do it on stock voltage.



Stock performance :800 MHz 7950 vs 925 MHz 7970..

Different settings

Do you actually believe that a 800 mhz 7950 underperform by 10 fps a 925mhz 7970 on max payne?

It's not. 4GB is the sweet spot for everything under 1440P surround and 4GB GTX 680s can use all of their VRAM in surround. 2GB is useless for surround.

The key word here is surround.

Running a single, 1080p, 120Hz, Monitor, I only come close to 2gb usage when I am playing Crysis 3.

Metro Last Light takes me up to 1.6GB. Both games are run at Max or near max settings.

A 1440p screen would probably hit 2.2 -2.5gb in Crysis 3.

Only AA,all other maxed out for both 7970/50.
Tested reference models:
800 MHz (non-boost 7950)
925 MHz 7970

SKYRIM and Battlefield 3 Multiplayer settings are tested equal for both 7970 and 7950,also maxed AA.

On rest games tested,MSAA has been lowered from 4x to 2x for 7950 against 7970,rest settings are same maxed out.

Very close competition between 7970 and 7950.
Hell only if 256 SMUs are not laser cut for 7950 and can be flashed as 6950 to 6970,then really it would be par with 7970 and a damnation for amd high end gpu business. redface.gif

You're exactly right.

Crysis 3 uses 2500MB of VRAM at 1440P maxed.

So generally speaking, yes GPUs can use a lot of VRAM even with current games but only in multi monitor setups or at 4K. Under multi monitor setups and 4K you don't need more than the 3GB of the GTX 780.

Do you think the performance hit from 4xmsaa is not big? Its different settings

On skyrim its 75 vs 81 and on bf3 57 vs 64. A 7950 needs more 80-100 mhz to match a 7970

This is probably going to start being my habit next time I upgrade. When a $200 card beats this Titan, that will probably be my next card. And get two of them while I am at it.
