Leaked benchmarks showing 15-25% gains over GM204 and Hawaii, huh? Looks like we've maxed out 28nm unless AMD can also pull a Maxwell and boost energy efficiency by a lot. I don't doubt that these shipping reports are 100% true, especially since they don't actually tell us much. We're due for a new AMD lineup; the 200 series launched back in 2013 after all, and the "tech demo" was released late in the 7000 series (GCN 1.1 in the 7790) and the Rx 200 series (GCN 1.2 in the R9 285).
Finally, assuming the HBM rumors are true (I hope yes but am expecting no - if you're never optimistic then you can never be disappointed!
) then this thing has an effective bus width of 5120 bits. The frequency is a fifth that of Hawaii's and the bandwidth is doubled:
2(512 bits * 5GHz) = X bits * 1GHz
X = 2(512 bits * 5GHz)/1GHz
X = 5120 bits
In a single cycle, that's 640 bytes or 62.5% of a KiB. Not bad! I wonder if latency will be an issue since the frequency is so much lower. Something like a single optical fiber has very low latency and bus width, but a truck full of hard drives has a much higher "bus width" at the expense of your ping times.

EDIT: And for the record, these things better not require hybrid coolers. They drive up the cost, they're not necessarily the best quality, and I'm not sure how comfortable I am liquid cooling a computer. (But if you know of any completely non-polar liquid that works in a typical waterloop and has a high heat capacity, please let me know.
