It implies that the Radeon 400 Series for desktop PCs won’t contain rebrands.

Not more typo propagation! That should be NextGen, not to be confused with NexGen ;)

Makes sense, you get many more chips to the waffer at 14nm

"more detailed" is rather an overstatement.

The time granularity is reduced to full years (is Vega launching in January or October next year? The previous one indicated an early introduction), and it doesn't say anything we didn't know before, except maybe confirm that Polaris 10 is covering the high end of the market too.

Quite how Polaris 10 is going to cover the high end of the market with what appears to be a 2560 shader SKU is beyond me - these SKUs must have far higher clocks (60% higher than Fiji?) and GDDR5X. Or it's a 3072 shader SKU, 33% faster. However no leaks to date indicate high clocks for Polaris.

I can't see a scale on the charts so it might just be volume rather than market segment (performance). Ie they're saying they'll sell an equal number of polaris 10 as 11, or target an equal number of market segments etc. in 2016, with no previous gen cards being marketed.

But really, it's just a fairly useless picture I agree!

I'm not sure on the shader count, but you seem to be assuming the move from Fiji to Polaris is a node shrink of the same chip. From what I've seen and read from AMD the two sets of architecture are very different.

Is it just me being pernickety or is there a reason that the numbering scheme for Polaris seems backwards, shouldn't Polaris 10 be for the lower end cards and 11 for the higher end.

Why? All of nVidia cards are also codenamed with lower series numbers being more powerful (GM100 > GM104 > GM106 etc.)

But AMD have clarified it's a chronological numbering, not performance based. They aren't user numbers either - it'll presumably be 480, 470 etc.

I'm already staving off for the Vegas series with HBM2. What could the next gen memory be if HBM2 is only going to be a year old?

HBM3 presumably ;)

Or perhaps they put two Polaris 10 dies on a carrier, using the same tech as used to mount HBM next to a Fiji die. If the yield drop off at high die size is bad enough, then that could pay for itself in increased yield across the wafer.

I think that Radeon wins this round against Nvidia and probably a few years ahead.

Brave call! What's that based on?

it could be nexgen - they might be adding an SSD to the video card!

From what I've read it seems they will introduce the lower end GPU's first which are based on a different architecture than the bigger Polaris 11 GPU's who will be released later on.

Few reports have reported that the earliest dates we might see the lower end GPU's appear is July.

I'd suggest reading from better sources in the future :p Polaris 11 is the small one and looks likely to be released this summer. Polaris 10 is the big one (but will also release this summer).
