If it will look like this then very nice GTX 1070 cards are coming. Imagine them overclocked to 2 GHz 6% sounds about right if you compare FLOPS.

Blower cooler cards for life!

Indeed, specially with MiniITX

GDDR5X already entered mass production

Today, I am happy to announce that GDDR5X, the fastest discrete memory component in the world, has already entered mass production.

It was actually already in their Q1 financial statement. Both HBM2 and GDDR5X is in mass production and there is going to be plenty of supply for Pascal cards

Its quite surprising to see GP106 got a 256bit interface according to the shipping information. That's going to set the bar quite high.

Perhaps I missed it, but has the possibility that Pascal is a straight up die shrink of Maxwell been discussed? The delta between a 980 and 1080 can be explained entirely on cores and clock speed (25% more cores that are 42.5% faster with 75% clock scaling), and the same can be said of the delta between the 980 Ti and 1080 (10% fewer cores that are 50% faster).

Based on that premise, a 1070 is simply an overclocked 980, and with a core clock likely to be 33% higher and 75% scaling on that clockrate, the 1070 will be 1.25x faster than the 980, or about 5% slower than a Titan X.

To be a bit cheeky about it, this is similar to the rebadge of the 290x to 390x, but with the added benefit of a newer process.

Or to be more literal, this is the original Maxwell design, delayed 18 months or so.

Certainly no.

It if got 256bit interface, then it will also get 8GB of VRAM

No, 8GB minimum only applies for GDDR5X usage. You can fit it with 4GB if you want. Even 2GB if they are still made. All at 7Ghz.

Samsung is even making a new 4Gbit chip for 4GB minimum 256bit cards:

[Kris194]

Well, it seems that only 8Gb GDDR5 are in mass production without any notice on EOL. Maybe this time GTX 1060 will also get 8GB of VRAM but at 7GHz, not 8 and without any architecture improvements it would have bandwith on par with GTX 970. 128bit interface in GTX 960 was kinda lame... Not to say that Polaris (GP 106 competitor) will also get 8GB of VRAM it seems and GTX 960 already got 4GB.

 

[ShintaiDK]

While you may see top bin GP106 and Polaris for that matter with 8GB. I would be surprised if you dont see 4GB versions too in that price range. As said, Samsung is releasing new chips for this. Also there are Hynix and Micron etc.

Really? Am I supposed to guess what is hiding under *? By the way, it seems that Polaris is very, very weak and Nvidia will really have no competition for a long time.

Nevermind, found it.

This was posted before. Something is weird with those numbers. The performance delta between medium and heavy batches is tiny.

 

[Arachnotronic]

$520? Wow. If you can get that then yeah, I'd sell. However most Ebay listings seem to be going for low $400s, with the fee + shipping that's like $340-380 net profit. Doesn't seem wise to take that kind of hit when we still have no concrete info on how Pascal performs.

What was crazy was that one of the guys who bought one of my cards, REALLY wanted the second one and actually offered to pay me $550 if the person who bought my other card bailed (didn't happen though) 'cause he wanted a matched pair.

The MSI 980 Ti Golden Editions were selling new on eBay for $570 at this time, BTW.

Anyway...the "price" I've paid is that I've been stuck on iGPU for a while but there is such a vast library of older titles that'll run on my iGPU that I can hold out

So why 1070 still uses crap slow DDR5?
Is Nvidia releasing 1070TI with DDR5X and 2304SP?With about 10% less performance than 1080 it will be great card.
The gap in normal 1070 vs 1080 will be 30% and more so there is room for that.

 

[ShintaiDK]

It uses 8Ghz GDDR5. With GDDR5X it would have a much higher memory/processing ratio than GTX1080.

 

[Kris194]

That's because they just started volume production of GDDR5X, Samsung started mass production of 8GHz 8Gbps GDDR5 back in January 2015 Not to mention that with GDDR5X it would have to much power. You know, here, in Poland, GTX 960 is the second most popular SKU, first is GTX 970. It means that you have to have plenty of GTX 1070 at launch. For example, back in September 2014 demand for GTX 970 was way higher than supplies.

 

[Head1985]

More reason to wait for 1070TI.

 

[Kris194]

You won't see something like 1070Ti. Next year they should release GTX 1080 as GTX 1170 or however they will call it They did the same thing with Kepler

GTX 680 - full GK104
GTX 670 - cut GK104
GTX 660 Ti - cut GTX 670

And next year they did this

GTX 780 Ti - full GK110
GTX 780 - cut GK110
GTX 770 - full, slightly overclocked GK104

 

[Head1985]

Even better.1080 for 400USD will be great card.

This is exactly what I assumed they'd do and if Vega 10 doesn't bring the heat then it's almost guaranteed.

But that's impossible based on a number of posts here on AT.

GDDRX couldn't possibly be on any GPUs until 3Q (at the earliest) because folks here said so.

People here said so because Micron said so. Micron just now came out and said that it has started production earlier than expected.

 

[LTC8K6]

I think we will see GDDR5X cards much earlier than most people expect.

I'm psychic.
