AMD Polaris GPU: detailed slides leaked

[HEXUS]

Claim "a historic leap in performance per watt for Radeon GPUs".

Slide embargo shown is 6pm today, so maybe some sites already have articles about this ready to go?

The deck says 4th generation, which most people would expect to call GCN 1.3, where does this GCN 4.0 come from?

Quite. AMD haven't given official numbers for GCN as far as I can tell, so either are probably valid.

Just seen a few of those slides in a video AMD just posted: https://www.youtube.com/watch?v=5g3eQejGJ_A&feature=youtu.be

Very true, perhaps this will be AMD finally revealing their numbering which is at odds with what the review sites have been using the past years

Official AMD press release just arrived, please see updated article.

before they launch NVIDIA would have sold 50 million GTX 950's

Is there a reference for this assertion?

Looks Like I'm going to build my first AMD machine.

AMD never used GCN 1.x names, and they're trying to get the media to stop using it as well.

Polaris is the code name for a set of modules, each at a specific capability. That includes what they are calling GCN 4 and what the media might have called GCN 1.3.

Hopefully AMD is getting things right now - teaser announcements with some meat in them is a good thing to see.

Where do they say that? I've only seen them call it 4th Gen GCN, which could be represented 1.3 or 4 equally well.

In fact, last year,AMD started calling "3rd Generation GCN" the Tonga and Carrizo implementations.

What i want to know is how their going to handle two different fabrication processes, aren't they splitting between TSMC whose using 16nm and GoFlo who uses 14nm?
If so does that mean there's going to be a split in the fab process used between high, mid, and low end cards, or is it going to be lucky dip?

Some card types will use a gpu made at TSMC, some at GloFo from the rumours. We don't know yet who is getting the low, mid and high end parts so you will just have to wait.

My guess would be that low end parts will go to GloFo to help pad out AMDs wafer purchase agreement in the face of lack of CPU sales. If high end is HBM2, then if TSMC is handling Fury then it makes sense to keep those high end parts there for now.

Lucky dip wouldn't make sense, you need massive volumes to dual source a single part.

[Corky34]

Yea i didn't think lucky dip would make sense but stranger things have happened.
It should be interesting to see where they draw the line, i wounder if they'll use one for HBM cards and the other for GDDR cards.
