Only 4 days to go...

Hmmm 120hz Monitor or upgrade my xfire 5870 cards to one of these -_- decisions decisions!

I'll be ditching a 5870 for this new card if i leap. otherwise I'm leaping to a 7 series

Its going to be so funny if it is a 512mbit bus, with 4 or 8GB of ram, £650 and still slower than a 780.

(Seriously I am not expecting this to happen)

Yeh I'm thinking of ditching the 5870 too.

It's been a good card and served me well but it's age is showing now!

Nice find, Hawaii is def looking good, I really don't want to be tempted lol.

+1 but fingers crossed it is true!

A controlled leak seems quite credible when it involves DICE, AMD's new best friends. Especially just a few days before the launch.

Credible yes but thats only the image of the engineering sample board with sheath on not the 2 PCB images or the rumoured spec. (it is actually an engineering sample in the top pic so as far as DICE having hands on thats probably true).

Ah, I assumed he was backing up the quoted specs.

Rroff · 21 Sep 2013 at 18:30

Nah hes just showing off he has his hands on one - DICE doesn't really have reason to lie about that so its pretty much a given that its actually an engineering sample VI board.

EDIT: The press have been putting those 2 together to make it look like its part and parcel of the same story tho.

Dice leaked the 7990 as well.

yes but as Roff has said it is only the full card image that is the leak the other images and the article guessing at 512Mbit bus are all just rumours.

Randomface74 · 21 Sep 2013 at 18:35

nah there's some science that if you have 4gb you need 512 bus

no idea what the science is tho

Thing is you wouldn't get 4gb on a 384 bit bus, would you? It definitely won't be 2gb so surely that would only leave 512 bit as the only option. As far as i understand it anyway.

What billy said.

Braided cables, LEDs and... barbs with generic black nickel clips?

Except that you actually don't as NVidia proved with their 600 series, some of which had odd amounts of ram compared to the bus width.

Jokester · 21 Sep 2013 at 18:37

Could be a 256bit bus, but I take it's still on GDDR5?

This is not Nvidia though Bru.

Have Nvidia used 512bit before? I don't know.

Have AMD? user 512bit before? Yes, the 2900xt.

No chance.

yes I know this isn't Nvidia, I was just saying that it is possible. 4GB ram does not necessarily mean a 512Mbit bus.

It could quite easily be 256 if they clock the memory to heck.

I think it's worth linking this again:
