http://www.cs.utah.edu/thememoryforum/mike.pdf), but essentially it works out to about a ~18-20w savings over using a GDDR5 interface. Which is pretty good, because that 20w savings is going to go directly into improving core performance (40% increase in shaders according to rumors). But unless games start using more VRAM, the bandwidth increase will not bring significant performance improvements directly, it will come indirectly from the power savings.
I'm not saying HBM is unnecessary, but given the obvious delays caused by it, I don't think it was worth the trouble for this particular card. Only the power savings is worth having, the doubling in memory bandwidth is unnecessary, in my opinion.
Huh? why would I downclock to half? And how would this prove/disprove diminishing returns on memory bandwidth? If a game requires 200gb/s of bandwidth, increasing my card from 224 to 448 isn't going to show an improvement in performance. In your scenario I'm going from 112 to 224. Of course it's going to have an effect, regardless to the core clock speed. Obviously they should be balanced, but that's my point -- they already are balanced and above the threshold for most games.
Regardless, if Nvidia/AMD felt like memory bandwidth was a concern, they could easily be shipping GPU's with a larger memory bus than they do now. Both companies have shipped cards with a 512 bit interface. On a Titan X, die size might be a concern, but Nvidia could easily fit a 512 bit bus on a 980. They didn't because it's simply unnecessary. Now HBM is a bit different, you get some power savings by switching to it, along with a doubling in available bandwidth. I did the math in a previous post (based on AlmondMan
Since my GTX 680 runs GTA 5 just fine, I don't see any point in upgrading anytime soon :| Will the 390 series finally deliver more than 100% more performance at less than I paid for the 680? If so, they may have a sale. But so far, no sale to anyone.

The rumor has been June, and still is June. Patience.

Can maxwell go that low in the clocks? On my cards lowest I can go is -105 on the core and down to 6ghz on the vram in MSI AB.

Lol, when peoples will stop to take rumors written by exemplary jurnalists on none less exemplary sites ( starting by F or W ) as facts.... they will maybe stop to speak about delay, or whatever..
- Computex of Taipei end the 8/6 2015
- E3 2015 start the the 16/6 2015.

Wasnt this already clear that they will reveal new cards at E3?? If computex was after E3 they could have cards there too but it isnt. (computex 1.june and e3 18.june)
More painfull will be the info about availability. Hope they have decent amount of products so I can start blasting with watts soon. 🤓

Patience is a virtue folks. The new 390X is revolutionary; Would you rather AMD rush the 390X? For those of you who are like "Screw it I am getting a GTX 980" grow up eh?

They are very late to the party. gm200 non titans will probably be out before then.

Will debut June 3rd @ Computex now.
