Evaluation samples are schedule to be available in mid-July, and AMD will begin shipping reference design boards with 1GB* GDDR5 memory at the end of the month, the sources detailed. In mid-August, AMD will also begin shipping the 4870 X2 (RV770XT) GPU to partners wishing to design custom cards, the sources added. HD 4870 X2 graphics cards are expected to be priced around US$499, the sources detailed.*unconfirmed reports suggest this card to feature a total of 2GB GDDR5 memorySource: HKEPC

Some reports suggest this card features a total of 2 GB GDDR5 memory. Maybe AMD wasn't 'MAD' in saying this card will overwhelm the GTX 280.

2GB seems a bit overkill for all the games out right now. Maybe when Alan Wake comes out it won't be, but I would rather have a card with 1GB and faster clocks than 2GB ATM.

You're forgetting, 2GB = 2x 1GB, in other words, the total graphics memory effectively is 1GB. How? Textures, shader, mesh, and other data are mirrored across both memory arrays. So the GPUs could do AFR (alternate frame rendering). To render alternate frames or even tile, both GPUs need to be served with the same data. So, if you think 1GB for HD4870 is ok, 2GB HD4870 X2 isn't really overkill. The RV770 can make use of 1GB, unlike MSI coming up with a 2GB GeForce 9600 GT.

yeah its probably gonna be 2 pcb's attached via some special internal crossfire interface, so the clocks will still be that superfast GDDR5

We already know the design will still be the 2 GPUs on one pcb. If it is 2GB of memory, it'll just use 1 gbit memory chips instead of 512 mbit.

£500 :eek: . I hope its not that much. It should be about £300 here in the UK based on $500 + VAT. If I can get it for that :D . Cant wait.

I wonder when retailers will start taking pre-orders?

199 = 4850
299 = 4870
399 = 4850 X2
499 = 4870 X2

hehehe, yeah, probably overkill on the cash like, but, I'm sure I can find something else to spend the rest on ...... nice new x48 cf board for me !!

Let's just hope those pre-orders come sooner rather than l8r !!
