NVIDIA Pascal Thread

I also believe in a Computex announcement. I'll be really disappointed if they don't!

 

[tweakboy]

Where is the 1080 price ???

I believe the announcement will be immediately after Polaris to screw AMD. Not the first time from Nvidia...

 

[airfathaaaaa]

They are suggesting the cards will be unveiled before Computex.

you still believe they gonna ninja'd them into the market without no one noticing on may eh? thats why you still havent changed your title thread?

Actually I never believed, that one was to piss off certain people.
Now that I'm over with it, changed it.

Makes sense. They'll launch the GTX 1070 in June/July to counter Polaris 10, and later in Sep/Oct/Nov they launch the GTX 1080 with GDDR5X.

 

[jpiniero]

Two 8-pin? Maybe Pascal really is Fermi 2.0...

If true, it doesn't mean a different time launch. As X80 the high-end model, quantity won't be so much a problem. Actually, it's smart to use different memory on these 2 models.

Hmm, still kinda risky to have a paper launch with GDDR5X memory. But i agree, better have two different memory types than crippling the GTX 1070 bus again to achieve the performance gap.

why paper launch ? Do you know real state of GDDR5X production ? I don't.
Besides, HBM2 shouldn't be ready before end of year neither...

Just some speculation based on current rumours.

Maxwell vs Pascal Bandwidth:

Geforce GTX 970: 196GB/s
Geforce GTX 1070 / X70: 256GB/s (+30.6%)

Geforce GTX 980: 224GB/s
Geforce GTX 1080 / X80: 320-384GB/s (+42.8-71.4%)*

Geforce GTX 980 Ti - 336GB/s

The first GDDR5X memory chips from Micron are marked as MT58K256M32JA, feature 8 Gb (1GB) capacity, and are rated to run at 10 Gb/s, 11 Gb/s and 12 Gb/s in quad data rate (QDR) mode with 16n prefetch.

 

[raghu78]

Having GDDR5X on GTX 1080 and GDDR5 on GTX 1070 means the GTX 1080 could have a larger perf gap against GTX 1070 as it will have 1.5x the bandwidth assuming 256 bit 8 Gbps (256 GB/s) for GTX 1070 and 256 bit 12 Gbps for GTX 1080 (384 GB/s). I think the perf gap will be larger than GTX 980 and GTX 970. So this would allow a GTX 1080 to be priced at USD 550-600 and a GTX 1070 at USD 350-400.

GTX 1080 can launch earliest by Sep as GDDR5X production starts in summer (June). GTX 1070 could launch in June as it uses GDDR5. Maybe next year Nvidia will bring a GDDR5X based GTX 1070 Ti because Vega 11 comes with HBM2 in early Q1 2017.

Now all we need to see is how does GTX 1070 and Polaris 10 perform and their price points.

I do, it's sampling.

That can't be any clearer. They even made a blog post in February which should have made it crystal clear to anyone expecting Summer GDDR5X.

https://www.micron.com/about/blogs/2016/february/gddr5x-has-arrived

There have been a variety of rumors in the industry about GDDR5X availability timeframes, so I’d like to clear that up from the beginning: Micron’s GDDR5X program is in full swing and first components have already completed manufacturing. We plan to hit mass production this summer. The team at our Graphics DRAM Design Center in Munich, Germany is doing a fantastic job, too. Not only do we have functional devices earlier than expected, these early components are performing at data rates of more than 13Gb/s!

If Nvidia is worried about Polaris 10 then holding back the 1080 for GDDR5X could make sense. They wouldn't bother if they could beat it with the 1070.

 

[xpea]

I know its sampling too, like everybody.
We also all know that the production is stated for this summer.
But many things are still unknown.
When exactly Micron will deliver the first batch ? (you know, because summer is 3 months long...)
What quantity ?
What bin ?
Is Nvidia even the lead customer ?

Correct my if I'm wrong, but as long as the chip is capable, isn't memory type and amount decided by the OEM?

I'm thinking at launch Polaris/Pascal will sport GDDR5 on reference cards but 6 months down the line we start seeing OEM revisions with GDDR5X. As I understand it both chips (Polaris/Small Pascal) are capable at the memory controller level, so the only issue is availability.

i dont believe it.1070 will be worst x70 or x60(in past GTX260 vs GTX280) card ever.
Cut down card with even more slower/gimped memory bandwidth..Worst crap ever.
If true my next card is vega11 with HBM2

 

[tviceman]

Paacal's launch is going to be the biggest slow roll in history. GP104 is going to launch with "slow" GDDR5X 10gb/s for the x80 part, and GDDR5 for the x70 part. Then in the fall, they will release another GP104 part with 10% higher clocks and 12-14gb/s GDDR5X for an easy 25% performance boost and that will be the x80 TI.

Insofar as GP100 is concerned, I don't think it's ever going to get a GeForce release. I now believe the rumors of the mythical GP102, and I think that chip will get a release early next year as the Titan, and then as the x80 TI in a refreshed lineup.

My opinion/speculation.

 

[Silverforce11]

The cutdown GP104 with GDDR5 and full GP104 with GDDR5X is a smart move. Because x70 has many times more market volume than the x80 SKU, so the ramping low volume GDDR5X won't be bottlenecking the x70 part.

Also, if x70 is around 980Ti performance, it can do just fine on GDDR5 only.

 

[Head1985]

If its cutdown by 25% and have 50% less memory bandwidth its not 1070 but GTX1060TI.
The gap vs 1080 will be like 40% with even lower clocks.

You're way overreacting. The same could have been said last gen with the GTX 970 you subsequently bought. But yet it's performance was good. So hold judgement til you see the performance. Specs only tell you so much but you've not seen the performance of Pascal architecture so don't judge yet.

Without seeing how games are coded and seeing how Pascal is performing once it's in our hands we don't know.

Also, as we've seen before, people write games sometimes with the hardware they have on hand, so if Nvidia is aggressive in getting Pascal out to everyone, games may not take full advantage of AMD hardware on the PC side.

There are just so many factors, we just have to wait and see. I just am not one to count Nvidia out ever, not because I'm some Nvidia fanboy, but they have proven to be extremely business savvy and incredibly ruthless.

Edit: Also, you know full well AMD isn't focusing on 1080p performance at all with their big chips. They never do. And you yourself have stated you're a 1080p gamer. Nvidia shines at giving the masses what they want. I have no idea why you'd want a big chip for 1080p gaming, but Nvidia will be the better big chip for 1080p gaming is my guess. My guess is Vega will continue AMD's high resolution dominance.

Also, if x70 is around 980Ti performance, it can do just fine on GDDR5 only.

It's brilliant if AMD can't compete on performance with GP104 until next year. My post above is going to happen, GP104 will occupy the x80 TI, x80, and x70 product with fast GDDR5X, medium GDDR5X, and GDDR5 memory.

 

[Adored]

For me it's an acceptable middle ground yes, with the low volume 1080 on GDDR5X. With the pent-up demand for the new cards it would be utterly stupid of Nvidia to risk losing 1070 sales due to a lack of memory.

I have to say that dual 8-pins makes me wonder at the veracity of this rumour though.

 

[Pinstripe]

If Nvidia is worried about Polaris 10 then holding back the 1080 for GDDR5X could make sense. They wouldn't bother if they could beat it with the 1070.

They *are* confident that 1070 will beat Polaris, or it would have gotten delayed with GDDR5X memory, too.
