Discussion On The ATI Radeon 5*** Series Before They Have Been Released Thread

But you aren't scaling everything are you? The memory speed/interface bandwidth, the PCI-Express lanes etc. Doubling some parts of the design will not necessarily equal double performance.

I mentioned memory bandwidth in my post. I doubt PCI-E bandwidth will be an issue.

What I'm saying though is that you shouldn't expect any internal bottlenecks, if ATI genuinely have doubled up all their units. Look at what happened from the 9800 Pro to the X800 XT, for example, or more recently the 3870 to the 4870 (though there ATI left the number of ROPS unchanged).

The bottleneck you mention, can be solved simply by shipping faster memory; without having to make any changes to the GPU itself. But as I said in my post I agree that, at launch at least, the 5870 may not have enough bandwidth to live up to its theoretical potential.

Agreed. Don't get me wrong if we get double performance from this, that's great news. I don't think we should be shooting down a site for suggesting that x1.6 performance is likely.
 
Is 300 dollars for the 5850 confirmed? May be a bit steep for me :(

What are exchange rates doing at the moment? I assume we aren't back to $2 to the pound?

EDIT: No it's not...looking to me like £200 for the 5850 and ~£250-275 for the 5870 :(
 
im happy with 1.6 rly, considering thw pwoer the 4870 has now. and the optenital for better performance in the future.

Looks like ATi have taken a leaf out of the nVidia cooler design book.
 
Sorry, long thread is long and I haven't bothered to read it all as the announcement is only today, so any and all before is speculation and rumour.

Meh.
 
btw wtfs up with the 2 red bits on the end...isnt that where the power goes? look like exhausts

They'll be air intakes and it looks like the power is now on the top nvidia stylee.

That is if they are the final card designs... *shrug*
 
i like the style of the air intakes lyk xD but i wont be buying even a single 5870. far too expensive! i guess ill have to keep my 4870x2. unless someone wants to buy it from me xD with waterblock or air cooler ;p

They're not air intakes, it's got a centrifugal fan, the fan draws air in through the center and dispels outwards.

If anything, it'll be a small exhaust where the VRMs are located for air to flow over them and be exhausted out of.
