Can someone explain to me how vega 8 gb of hbm2 will compete with 1080ti 11 gb gddr5x?

would nvidia have even turned the 1080 ti into a titan killer without amd's vega threat?

I know the gddr5 is like 2-4 times less needed compared to gddr 4 and 3.

can you talk a little bit about how trounced nvidia will be by this hbm2 threat?

Anything you read now is pure speculation and guesswork.

The 980ti did the same thing last gen. This is just Nvidia being Nvidia.

"It's not how much and how fast your memory is, it's what you do with it."

HBM2 is supposed to be able to support up to 16GB of memory, I think. So that would top most of Nvidia's Geforce cards. Though they already have HBM2 equipped cards of their own (Tesla models).

Since Nvidia seems to be pursuing the cheaper path of even faster GDDR5X 11 and 12 Ghz stuff, it may be a wash, with their cards already around 500 GB/s of bandwidth, and a potential HBM2 at 720 GB/s it isn't as huge an increase as it would seem.

AMD's cards are likely to have the same smaller footprint of the Fury line though, and I wouldn't be surprised to see more OEM water cooling.

ah man, no ones got a fury. I hope you're wrong.

Well you certainly can't get them anymore, but they were quite popular with AMD enthusiasts. When they were released they were in every build. Still one of the fastest cards you can get in a tiny form factor.

Though I think Zotac has a pretty small 1080.
