Probably disable 512mb of the larger card's VRAM, same as they downclock a card that is clocked higher.

HD4870 512MB GDDR5
HD4870 1024MB GDDR5
HD4870X2 GDDR5

The GDDR3 4850 launches later this month, the 4870 (and maybe GDDR5 4850) will launch as soon as GDDR5 availability is high enough. I think the 4870 will paper launch alongside the 4850, but not 100% certain.

I for one am interested in the HD4870 1024mb GDDR5 card. Is that the one that is rumored to be going for $349?

You forgot the 4870 GDDR3 releasing this month.

ATI took 2 years to make a card that undercuts the GTX's price by 200 and is better. Pretty good.

Has it been officially announced? From what I know, the release of the HD4870 has been delayed until June so that the 4870 will only use GDDR5.

I'm not sure if there's any definite info for the retail prices yet. The deal with the 1GB card is that ATI will support the 4870 with 512MB memory, but it would allow vendors to use 1GB.

I want to know if the 4850 will have GDDR5. Because when I see a 4850 on newegg I want to buy it. But If I buy the 4850 with GDDR3 Then a week later a GDDR5 one comes out Im going to be pissed.

If you're smart you will be waiting 3 weeks or so for prices to drop before buying one anyways.

Don't forget ATI and AMD were getting it together through the merger, you could say tech right now is 6months-1 year behind, than if AMD and ATI went their own seperate paces.
