Gigabyte HD 6870 vmodded - running 1200 Mhz GPU aircooled
- Thread starter Final8y
- Start date
Just trying to keep a little perspective on things... more than one person was claiming them to be great overclocks... when infact they are distinctly pedestrian if you look at almost any other card - almost any current card would manage 30% OCs with 5C ambient and a big voltage bump.
Thats as maybe heh
I said it was a high clock i did not say it was a good overclock because in percentage it is not & i think i can only see 1 comment in here that could be taken as someone saying its a good overclock.
I only care about the final clock & not the percentage of an overclock because the percentage can mean nothing if the starting point is low as you can still end with poor final performance.
I would rather take a 480 with a 1000Mhz stock clock but only over clocked to 1100Mhz than a 480 with a 700Mhz clock but over clocked stopped at 850Mhz.
The final clock gives the performance not percentage of the over clock & on top of that comparing over clock on completely different architecture is irrelevant.

Probably not that close, I'd imagine at those kinds of clock speeds the memory correction would do all kinds of terrible things to performance.
If both products where the same price range then your comment would have a little more relevance.
My bad!

Isn't the perspective here the clock acheived tho? Everyone knows the 480 is twice the price nearly and clocks to about 800-850, this card goes to 1200 on air, impressive. If were comparing it to the 5970 does this also mean it's crap lol?
Anyway, hope my point is understandable
It is true tho that it's still nowhere near as impressive with overclocking scaling, has anyone worked out yet why overclocking 20% on ati cards yields much less in performance? Only moot point at the mo, I hate not getting nice gains, I didn't bother taking my old 5870 to the limit as it yielded such pitiful fps gains

Links i want to see 1200 on air.

He never made 1200 stable from what I can tell, max that was benched was 1105 core, and from 900 core the gains were poor.
Title is missleading.

I'm talking about % overclocks.
I think the reason why ATI cards don't scale so well with clocks is because there must a bottle neck elsewhere in the design of the card.

Didnt ati say at one point that there was a problem with going too fast as something like the shaders scaled badly or became really inefficient? That was at least a year ago mind.
