ZOMG major GCN revision confirmed! GCN 1.0 -> 1.1 -> 2.0
probably just a typo or marketing naming slip or something?
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).Could you comment on the Cape Verde / Oland / Pitcairn(Curacao) thing, too?
Since AMD does list them as supporting OpenCL 2.0 in HD8000M series and later, but not in HD7000 or HD8000 (OEM) series

Has Iceland been reviewed anywhere, by the way?

If you are able to say so, does Iceland (the full chip) have a 64bit or 128bit memory bus? DDR3/GDDR5 or only DDR3?Iceland is mobile only (headless). I don't know what its mobile codename was.
First Euro-dealer prices and delivery dates for Radeon R300 models from Gigabyte, MSI and Sapphire

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

Hilbert Hagedoorn; Guru3D said:Media & press do not have samples just yet. Next week there will be an event about Series 300 among others and hopefully somewhere next week the sample should be here as well.
The announcement date is E3 the 16th during the announced livestream and later that'll be followed by the reviews. I can't share that date though.
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.

The GeForce GT 750M (GDDR5 model) is roughly 30% slower than the Radeon R9 M370X, which is another 30% behind the GeForce GTX 950M
The Radeon GPU cannot maintain its core clock of 800 MHz. The clock often fluctuates between 675 and 725 MHz, but occasionally drops to 400 MHz.
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.M370X? As I posted before, it seems to be a prime candidate for beingGCN1.2GCN3.

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 ones375w ouch
