AMD Fury memory interface 4096 bit

Dx11 has a huge cpu overhead the API is at best broken and you need to do a lot of work to manage it.

windows 10 will make a better use as Microsoft adapted Mantle codebase and did create Dx12 from it that allows overhead to be gone and drivers to function and drive games better.

AMD it seems made more effort to be ready for windows 10 than fixing the mess dx11 is.
 
Because it isn't really needed. The GTX980 has a 256bit bus and competes with and beats the 290X in most normal gaming situations despite it having 512bit.

Overclocking the RAM on a 980ti makes a very small difference but core overclocks make a much bigger difference

AMD just seem to love making really expensive mistakes.

The memory bus just means they made the door wider so data can leave the room without restrictions. However the GPU that pushes the data along is still using a slightly modified design from 2011 which doesn't seem to have enough speed to able to take advantage of the extra bandwidth.

God only knows how fast Maxwell would be if it was using HBM, AMD would be in kinds of problems right now.

AMD told us that you dont need as much memory with a wider bus. They also told everyone that Fury X was going to be the best thing since sliced bread. In reality, its probably the best thing since burnt toast.

Its their biggest selling point, and when a company shouts as much about it as they have and it doesnt deliver anything, you have to wonder.

Because AMD for some reason are obsessed with memory bandwidth, when it isn't very important at resolutions that the majority of their potential customers play at.

They seem to be obsessed with making cards for 4k...that can't make playable framerates at 4k unless cross fired. But then they are going for an even more niche market - multi gpu 4k screen owning people.

This is why they haven't made much money in the gpu market recently :p
 
I wouldn't shoot it down so fast just yet.. Directx 12 is coming we already seen games like battlefield 4 enjoy the extra bandwidth from a 290x..

Am sure some you guys are going to get a real eye opener once directx 12 drops and benchmarks start rolling in...

You can mark my words on this.. Go on bookmark this post.. :D

Everyone will have a pascal card/Fiji 2 by the time DX12 becomes mainstream so no one will care how the Fury performs by then :p

Like I said before.. 290x has hold its own over these past two years... The furyx will be around much longer mark my words.

Plus not everyone upgrades all the time. Directx 12 is going to benefit a lot of people.
 
Fury X reminds me of the HD2900XT. They strapped a massive memory subsystem to that in the hopes that it would make up for the woefully inadequate core. We all know how that turned out. :rolleyes:

Feel sorry for AMD. Remember when the HD4870 came out, it was a genuinely awesome card, totally caught nvidia off guard. Then they went on a roll for few generations, in particular the HD5870 and 7970 which were actual flagship cards, coming out well ahead of nvidias offerings. Now they are just about managing to play catch up.

I'm not so sure there shanks, as it is at the moment AMD have said they intend to work on a game by game basis to get the best out of 4GB HBM. So once HBM2 gets here with fury 2 16GB cards, the working on a game by game basis for 4GB will go by the wayside, leaving fury 1 adopters high and dry.

Of course it might not happen like that, AMD might be really terrible at working things out game by game, so by the time fury 2 gets here people wont notice the difference anyway. Or maybe AMD will get things spot on till fury 2 and then keep up tuning things for 4GB as well as for higher amounts of memory.

Bottom line I don't think any of these last round of 28nm cards will last once we get to the new process next year.

Are you suspecting that even just switching to the DX12 api on Win10 (but still running DX11 games) will bring improvement? Serious question.

I only ask as I feel that their's a lot of untapped potential within the GCN architecture...

Well,I need an upgrade myself(only on a GTX660 ATM). Thinking a GTX970 but ATM not sure whether I should suffer for another year with the GTX660 or get a cheap GTX960/R9 380.

I get the impression 14NM/16NM might be a decent upgrade if you are willing to spend a few hundred quid.

I think FO4 will probably make the decision for me.
