AMD: Pirate Islands (R* 3** series) Speculation/Rumor Thread

GCN2 = press invented GCN 1.1

 

It shouldn't include Pitcairn, Verde, and Oland; Tahiti had some extra compute functionality and I recall that being a target but I don't know which side it landed. HD8000M series includes parts based on Iceland which is the same arch as Tonga (GCN3).

 

Has Iceland been reviewed anywhere, by the way?

The OpenCL 2.0 list separates HD8000M series to their subseries', for example HD8900M which is Nepture (Pitcairn/Curacao) only, and all the others, Iceland surely can't cover all of of those?

 

I guess no. But which product is it anyways?

Given that there are articles 1 year old stating that Iceland is set to replace Cape Verde.
But Cape Verde is Chelsea, Heathrow, Venus, total disaster if you ask me.

Maybe Cape Verde is also Iceland in the Radeon R9 M370X.

 

Can't they just go back to naming chips with numbers?
I got no clue which chip means which product segment now except for a few at the top/old top

Ermergherd

 

Iceland is mobile only (headless). I don't know what its mobile codename was.

 

If you are able to say so, does Iceland (the full chip) have a 64bit or 128bit memory bus? DDR3/GDDR5 or only DDR3?

 

Terrible news if true. Radeon 290X cards can be had for around 300€, depending on weekly promotions here and there.
With the 390 apparently starting at 50% more than the 290X, and the cut-down Tonga R9 380 at practically the same price as the much more powerful 290X, this new generation is going to be completely obliterated by reviewers and customer opinions.
.

This only means that AMD's marketing department did their job wonderfully. By rebranding not only the cards' names but also even the internal names they use for the chips, they will successfully convince some people that the R7 370 is not using a ~3.5 year-old chip that won't support any of the new (or actually rather old already) features like TrueAudio and FreeSync.
They'll be fooling customers like real champs.

Let's just hope that this actually brings some money into AMD and helps them keep afloat.
Even if it's at the cost of their popularity, maybe the marketing department's apparent masochistic madness with the purposely dishonest naming schemes will keep their talents' jobs until they can get around with the 14/16nm GPUs.

 

if full rebrands there might be a backlash that sinks amd for good.
if tweaks and refinements it might save them.
wouldnt want to work at the PR department atm.

 

At least 128 bits with GDDR5.
It cannot be anything different.

 

M370X? As I posted before, it seems to be a prime candidate for being GCN1.2 GCN3.

There's a proper review out now, they say,

and that it throttles,

I wanted to check out the numbers, but they seem quite wonky and all over the place with different laptops seemingly running different clocks and throttling differently?

No TDP figures confirmed, but if we assume that it uses same power as the maxwell chip, 30% behind doesn't sound too bad or does it?.

OEM strings from the latest Catalyst drivers show that Iceland is used in R5 M315, R7 M340, R7 M360. No mention of R9 M370X though.

 

If so, then I stand corrected and this thingie, which is described in notebookcheck as "a new derivative of the Tonga chip",

comes with 64 bits DDR3 memory. WOW

375w ouch

 

Sapphire seems to list the maximum provided by the power connectors, as for example all of their R9 290(X)'s with 6+8pin list < 300W rather than the actual TDP, including stock ones

edit: Corrected to < 3, damn automatic smileys

 

8GB of GDDR5 probably uses a bit of power.

 

yea I get that BUT PR and marketing is not doing their jobs as if that gets out people will know it as 375w vs what the actual use is.
its just not a good idea by far to post it that way
