Re: Which GPU (7970) really does 720+ out of the box?

I mine LTC on both sapphire and gigabyte (WF3) cards, and the gigabyte ones are infinitely better.

I get about 720khs per card (vs about 660 on the sapphires) with the following settings:

Core: 1045
Mem: 1500

Concurrency: 8192
Vectors: 1
GPU Threads: 2
Worksize: 256
Intensity: 13

I wish I had only bought the WF3 cards..

What card are those specs specifically referring to? I'm curious as to how you are getting 720khs out of a card on Intensity 13/TC 8192.

Side question, I have a Sapphire Vapor-X 7950 which I seem to peak at 630khs. Would a comparable Gigabyte 7950 be that much of an upgrade on performance?

What that guy posted is a 7970. This is a thread about 7970's after all, not 7950's.

Which is why I said it was a side question and wasn't comparing his 7970 to my 7950. I want to know which 7970 specifically. And there's been talk about certain 7950s being better than others, I wanted to hear further on people's experiences with this.
