AMD Radeon 300 series GPUs will launch mid-June, Fiji XT GPUs following later

That's only 4GB though and he said he would rather have 8GB;)

same amount of vram shared between the two chips.
8gb vs 8gb innit.


Two 8GB 290x are slightly faster, especially considering they can be overclocked very highly, unlike most 295x2s because power delivery (excluding the two custom ones).
 
A 295X2 for an ITX rig would be fine but I wouldn't want to run a pair because not enough vram or power delivery. Although I can appreciate they are massive, which is very cool in itself.

Same number yes. Not shared no.. You know it's split between the two.
 
If its two cards, it is mirrored not 'split'. Meaning GPU 1 and 2 have the same data Technically x2 cards work in the same way for the most part too.
Mirrored would imply the fact they the data is identical and they are not.
It is split. GPU 1 has all the odd frames. GPU 2 has the even frames. They alternate and the data is separate from the two and corresponds to whatever card is processing it. Now in SFR when they are rendering the same frame it is split between the two with each card rendering either top or lower half of the same frame, while not mirrored, it's closer to that than split. You can argue with this all you want, I pretty much just summarized a PDF from Nvidia.

The 8GB Vapor-X is a beast! Also EKWB makes a custom waterblock if you want to go crazy. [The 8GB card also comes with a cheaper tri-x cooler that can fit the same EKWB waterblock]
 
Which is what?... case, fans, fan size & fan setup? :)


It's a Rosewill Blackhawk Ultra case.

It has four 140mm fans in the front, one 140mm fan in the rear, a Silverstone Tundra TD02 cooler on top with four 120mm fans in Push/Pull, and a 230mm fan on the side that blows at the GPUs.

It has a lot of room inside and lot of options to customize it.

Both cards have the same data stored on their ram. Thats the MIRRORED bit. all the data is not stored on one card.

You can't have the exact same data on either pool of memory when they are processing different frames. Unless you can provide some reliable data I'd be interested in reading it as I would like to know how that works.

Careful, He never backs down...... ^_^

I only bring up counter points when I feel I can make a valid argument.. which an Nvidia pdf on the matter seems pretty reliable to me.
