Thread: Why 7970 GHz Edition 6GB work like a 7970 classic ?

| can you explain what you mean by this? the amount of memory does not effect the speed, and especially not with lite since it uses no memory. it will work just like a normal 7970, just about 5% faster ... |

| nope, memory has nothing to do with it.
even though 7970 runs at a higher clock rate, 6990 is faster because it has more stream processors. 6990 is a 5.1 TFLOPS card, vs 7970 which is only 4.3 TFLOP... |

Thread: Speed on Radeon HD6970
Post: RE: Speed on Radeon HD6970
| correct, you can essentially cut atom's 6990 speeds in half. it will be a little bit faster due to higher clocks, but that will give you a good estimate.
I believe d3ad0ne may also have some 6970 ben... |

Thread: Good budget GPU ?
Post: RE: Good budget GPU ?
| 7970 is a budget GPU -- you just have to budget a little more for it. And considering its MSRP was half of what the 6990 was, it's quite a bargain.
but seriously, don't waste your money on cheap, low... |
