They're using a revised core so yea

Revised in my vocabulary does not mean new, it means updated or "tweaked" but ATM there seems to be too much speculation and insufficient fact.

Have you seen....

lol, manbearpig!(love south park)

This should be a good card, the 4870 X2 has already proven it self in the market and this revision should take it to the next level. :rockout:

Even tho i dont need to much power at 1400x900 so i wont be getting it.

damn and wouldnt you know it.....my 2nd HD4870x2 will be here tomorrow.

I can appreciate them not wanting to release a crappy x2 product. Nice move AMD

It's nice to see they are at least looking to design improvements beyond a die shrink and OC.

You could CF a 4830 with your 4870, but it would effectively drop your 4870 GPUs down to 575mhz and drop the ram substantially. So yes you could use the newer card, but it would just time it back to 4870 specs.

It no longer works like that.

Each card runs at its own default settings and adds as much to the rendering as it can.

A 4870 crossfired with a 4850 would have a load balance in theory of about 60% for the 4870 and 40% for the 4850.

If it's RAM you're talking about though, that does get set to the lowest amount. Pair a 1GB card with a 512MB one and they will both only use 512MB.

When you say "load balance" do you actually mean "scaling" ?

agreed . . .

although, I think these revised cores will have what's necessary to make the 4890x2 a reality. Smart move to see how the single card performs first, though.

Man... Let's hope they know how their cards perform before they launch them...

true, and I get the impression these new cores might be a pleasant surprise to everyone . . . but I doubt AMD will release a dual-core card unless it'll reclaim the performance title from the 295 beastie.

One thing we've seen, though, from the RV700 series . . . they perform and scale superbly when coupled with GDDR5 and nice clocks.
