Presumably AMD are aware of the problem, what would it take to revamp crossfire at a hardware level, is there any reason they wouldn't?
Looking forward to the announcement though. I wonder if $599 gets you a copy of BF4 aswell...
I kind of wish they would bring a new feature set along to the table like HDMI 2.0 or game streaming to a tv dongle or something but that's probably wishful thinking. This is a genuine question but what makes these cards any more expensive to produce than a Kepler (If the leaks are true)?
To answer the second part, die size, 512-bit bus, etc. Essentially the bigger and more complex the die, the poorer the yields per wafer.
For the first part, we don't really know if there is a "fundamental" architectural hurdle in the way of crossfire and multi-GPU gaming. I think most of this is speculation based on the 4 megapixel frame limitation of the crossfire bridge. However, at least for the present, there are no single displays greater than 4 megapixels as all 4K displays are currently tiled (two displays in one), so at some point the image has to be split up regardless. It's outputting them to the display stream at the right time that seems to be the issue - which suggests a software timing solution. And if Nvidia can make it work reasonably well, then there's always hope for AMD...
There's a ton of hope for AMD- and in reality, there's very little reason to doubt that they won't get it right. That's why I'm really looking forward to these cards. If they screw up, we'll know it. If they don't, they'll probably far and away the best solution for 4k gaming for your money. Give me pixels or give me death .
