The seams are really starting to show when a change in memory and getting a competent cooler made by somebody else just about blows their wad. Everything besides that is flaky, and given the serious limitations for tweaking on a card that sold itself on being capable of being tweaked, I wonder if that water cooler is just there to keep the silicon from leaking to death, because right now it cannot even touch the max dissipation of that solution.
Is there a description of what is being performed for that test, the format, or how the result is calculated?
Other tests show almost 64 Gpixels per second in throughput, so I am trying to get a gauge on how that relates to the GB/s figure for the compressed figure.
I'd like to think better of their designers, but the implication is more dire. I suspect they knew they needed to do more, but everything about Fiji's launch makes me think AMD simply can't.The only way I can explain Fiji's existence in its current form is by assuming that AMD got complacent by the performance of Kepler, more or less the same as GCN but already touching reticle limits with GK110, and being massively blindsided by Maxwell. They probably thought that just touching the memory system would be sufficient to soar about whatever Nvidia could come up with and left the efficiency of GCN what it was.

One of the other tests had the 290X slightly edging Fiji in fillrate.That's an interesting graph. I think what we're looking at here is not worse color compression, but a different bottlenecks coming into play. When using color compression, it's hitting some non-memory BW bottleneck somewhere (one that's very similar than TitanX), while without compression, it gets much better results than TitanX due to the HBM that's provided by the extra BW.
