Nvidia Geforce 'Maxwell' Thread

Gregster · 3 Jul 2014 at 19:01

2x4GB 760s. The early Maxwell on 28nm looks to be decent in power efficiency but not in power. The later Maxwell (next year possibly) will be 20nm and should be a nice boost on todays top GPUs.

Maxwell all taped out, full fat confirmed to be on 28nm!! D:

One of Charlie's paying customers lets it slip in the forum. It seems TSMC's 20nm is being given a a wide berth by both red and green. We truly are wandering in the desert.

Someone from Scan commented in the thread on OCN suggesting they're coming no time soon.

Would that be after the 6GB Tis finally get here?

I have a terrible itch to get a new GPU and I've been doing my best holding off for 20 nm, they better come soon!

What a huge disappointment.

When you say full fat? Do you mean GM210 on 28nm?

If that's released this year, I would grab one for sure. Would much rather that than GM204 on 28nm.

Yep. Unless I'm misinterpreting it.

Is the high end Maxwell going to have a separate ARM processor to offload certain functions? I'm sure I'd read this was going to be the case somewhere.

Be awesome if it was a proper high end card this year. Would mean AMD are bringing something decent as well.

On-die (part of the chip), not sure if it's 100% confirmed but yep.

I find it hard to believe that the full fat Maxwell design is coming on 28nm - nVidia weren't happy with 20nm for it let alone 28nm and were pushing for 16nm finfets, the original design would have been stretching the capabilities of 20nm.

Hurry up Maxwell! want card faster than a 7990 & quieter

So what is there to believe? Nvidia are being very sly on this release and I hope they don't disappoint.

It is hard to believe, it would be worse than Fermi. Maybe NV will just bite the bullet and use TSMC's 20nm.

I guess another possibility they will savage other areas i.e. reduce the memory interface to as small as they can get away with, massively drop ROPs, etc. cut out anything non-gaming from the GeForce cards compute wise i.e. reducing caches and so on.

Isn't that exactly what the rumours are? 256bit, low ROPS etc

Rroff · 5 Jul 2014 at 19:32

Only based on some unverified shipping information afaik?

This card has two msata slots on the backside of the PCB:

^^ http://blogs.nvidia.com/blog/2014/06/24/nvidia-gpu-arm-hpc/ look at the image in the middle of that page.

At a completely wild guess I'm assuming its from a RM1905D development platform.
