Rumor: GeForce GTX 1080 8GB gddr5x based on Pascal GPU in May
Well, at least I have a nice juicy rumor just in time for the weekend. Asian based Benchlife claims that Nvidia will release a Pascal architecture based GeForce GTX 1080 with 8GB gddr5x in May. It would make sense as HBM2 will be available in volume only later in the year.
There's a precise date being mentioned as well, May 27th, four days prior to the Computex exhibition. Obviously Nvidia is not going to comment on this rumor.
The GP104 based GTX 1080 would get a 256-bit memory controller tied to 8GB of gddr5x memory. The usage of gddr5x over regular gddr5 is rather speculative as it isn't even in volume production that we know of? Micron (the only one that will fab these gddr5x ICs) announced in a recent blog post that they intend to commence high-volume production of GDDR5X chips in mid-2016, or sometime in the summer. But who knows, Nvidia have gotten their hands on an early batch for a couple of thousand cards right ? GDDR5X is your standard GDDR5 memory however, opposed to delivering 32 byte/access to the memory cells, this is doubled up towards 64 byte/access. And that in theory could double up graphics card memory bandwidth.
Early indications according to a presentation show numbers with the memory capable of doing up-to 10 to 12 Gbps, and in the future 16 Gbps. So your high-end graphics cards these days hover at say 400 GB/s. With GDDR5X that could increase to 800~1000 GB/sec and thus these are very significant improvements, actually they are competitive enough with HBM.
Pascal GPUs are fabbed in the Taiwan Semiconductor Manufacturing Company (TSMC) (recently hit by an earthquake) based on the new 16nm FinFET process. 16nm should result in significant power savings. The card would only need one 8-pin connector for power needs. The card would get a DVI, HDMI and two display ports. From the looks of things, and as expected .. this is not 'Big Pascal' GP100. That GPU would get 17 billion transistors made on the 16 nm FinFET+ node at TSMC and likely the HBM2 memory.
So to recap, in the latest prognosis Nvidia are rumored to launch the first high-end GP104 GPUs with models GTX 1080 and GTX 1070 (should Nvidia use this naming scheme). These chips would come in a 37.5×37.5mm BGA package, and get 2152 pins.

I doubt that i will go for these , best wait just for now and see what else Nvidia have planned , i dont fancy buying a 1080 just to find out 6 months later the 1080 ti might show up and all those that bought the 1080 will see it drop fast in price and wish they had held out on buying it , also High bandwidth cards will show its face to at some point this year maybe .
Nvidia will drag the card releases out just to milk as much as they can from us as always .
I'm really interested in giving AMD a go at sometime in the near future, i would have done with the furyx had it had 8gb vram , you can argue that AMD do seem to be offering longer support for these cards ,, look at recent benchmarks for the r290x it smashes the 780ti , link to benchmarks http://www.guru3d.com/articles_pages/the_division_pc_graphics_performance_benchmark_review,6.html

The 390/390X smash even Gtx 980 in DirectX 12 Hitman.
But with your Gtx 980TI SLI no worries.

No way is a card designed for 1440 or 4K gaming going to be called a GTX 1080.

The first Hitman was the same way. A 7970 was almost 20% faster than a 680 in that game. AMD partners with IO on it though, it's to be expected.

Lol, this is actually a good point. I've been trying to refer to the card as GP104 because I'm really not sure they are going to continue with that naming scheme.

I'm not impressed by these specs if they come out true anyway. Beside the specs I would really like to see how these will perform against 970 and 980. If they perform just slightly better I may skip those and wait for Volta. Though I doubt these will be weak in any way. Time will tell.
