So much for the almighty HBM2, it has the same bandwidth as a Ti, except you know like most of us my Ti is running at 12ghz memory so that's well over 500gb of bandwidth. If HBM1 is any indication it won't OC very well and end up being worse than GDDR5x.
Unless HBM3 is leaps and bounds ahead then I'd say GDDR6 is the future.
You could actually double the bandwidth of HBM by using more stacks, like NVIDIA does on their GV100 GPUs - but of course more stacks cost more money (and GV100 costs a fortune, but its a "pro" datacenter GPU).
In any case I tend to generally agree. HBM is largely overrated for consumer use. To get an actual bandwidth advantage you would need to use 4 stacks, which costs a lot of money, and at 2 stacks GDDR5x and the future GDDR6 will match or even beat it - at a lower pricepoint at that.

My Gigabyte G1 1080, consumes 216W (capped by BIOS) and it still has Power perfcap at that wattage limit.
But of course, it's overclocked and it performs very well for that Wattage, between a 1080 reference and a 1080 ti reference.
I'd like to switch to AMD in a future, but I hope AMD has a good alternative regarding performance/powerconsumption. If it's just a few watts more worse than nvidia (like 30-50 watt) I'd buy, but not more.
At the end, it should help the market and benefit all of us, if nvidia has some competition in the hi-end.

425watts on the vega 64 LCS... that's a whole system by itself lol, maybe the 1200+ watts power supplies might start selling more again
Looking forward to your review HH, hope it comes out Better than the rumours so far
Wasn't that Vega Liquid cooled model 345W vs 295W of the air cooled vs 215w of the 56 model.

I read several times that these numbers are only GPU power, not the entire card. Don't know if true.
I sure hope the 56 model turns out to be a lot faster than the 1070, that's the most interesting one for me.

Awaiting general power consumption results for ordinary tasks before deciding on this.
