    AMD alledgedly did state 'full DX12 support' according to that supposedly leaked slide (if it's genuine), so unless they're lying... Of course, GPU manufacturers often lie with PR, so one can't stake one's life on this statement being correct... :p

    The only safe assumption to make is that unless anyone says they support a specific feature level, when they say they support DirectX 12 they mean they support the low-level API with FL11_x.

    "IPv7" branch also has "R9 200 series" under "Hawaii" node.

    AMD does not define explicit OEM strings for individual card models anymore, for whatever reasons - if you look at their INF files, the different variations within R5/R7/R9 families are all combined under "Rx 200 series", and only rarely as individual models like "R5 M255".

    Yes, but that doesn't imply "full" DX12 support, much less jive with explicitly stating "full" DX12 support, or not to me anyway. ;)

    New range of prices for the 200 series, which may also be what to expect for the 300 series rehashing:

    [​IMG]

    So:
    - Fiji is a new chip that should go to the $400 to $600 range.
    - R9 295X2 should still be faster than Fiji so it'll still be in the market, but for $650 which is not a lot. This is such a niche market that I don't expect them to re-release it as R9 380X2.
    - Hawaii in R9 380 and 380X goes $270 to $300. Perhaps $350 for 8GB versions if those become more mainstream.
    - Tonga Pro in R9 370 goes all the way down to $200, to face the Geforce 960.
    - Tonga XT in R9 370X occupies the current R9 280X in the $230-240 slot. It can't be much more than that because Hawaii Pro will be already too close at $270.

    R7 300 series is the biggest unknown for me. I figure Bonaire will be in the R7 350X for the $100-ish price point, but there's nothing post-GCN1.0 between $100 and $200 which is a huge gap.
    Perhaps there's a 2nd new chip which is a Pitcairn with a Tonga-ish treatment -> GCN 1.2+color compression+TrueAudio+XDMA Crossfire+more ACEs+higher-density memory controller+slower/cheaper GDDR5 (less memory bandwidth compensated by color compression). This would be a crucial chip for AMD's midrange IMO.

    Looking at how the iGPUs in APUs are evolving, I doubt AMD will bother to make anything below Bonaire's performance threshold. They may re-re-release Oland (6CUs) and Cape Verde (10CUs) as R5 300 for OEMs but I think in the stores they'll keep their old R5 200 labels (like what they did with the Radeon 8000 series).

    Same source:

    But I don't know how trustworthy it is. The screenshot above would be quite easy to fabricate.

    Why would he censor the memory amount and GPU model name while leaving a bunch of other potentially incriminating stuff like driver version?
    He claims his card is %50 faster than a GTX 980 in compute because he can't test any games.

    In a post made a bunch of months ago, he claimed to be 17 years old.
    Either this is a kid getting his hands on his father's top-secret material from his job and now they're both up for some consequences or it's just bullcrap.

    He said it's 70% faster in compute. I'm guessing he's talking about some compute benchmark.

    The 15.200.1018.1 drivers are publicly available, they're the latest AMD drivers from Windows Update for Windows 10

    Yep, but the publicly available driver only has device IDs for the R7 300 series - so in the end R7 360 is indeed Pitcairn/Curacao, and not R9 370 as reported earlier based on Catalyst 15.3 beta INF file.

    C:\Windows\INF\oem5.inf
    Code:
    [Strings]
    AMD6810.1 = "AMD Radeon R9 200 Series (Engineering Sample - WDDM v2.0)"
    AMD6810.2 = "AMD Radeon (TM) R7 300 Series (Engineering Sample - WDDM v2.0)"
    AMD6811.1 = "AMD Radeon R9 200 Series (Engineering Sample - WDDM v2.0)"
    AMD6811.2 = "AMD Radeon (TM) R7 300 Series (Engineering Sample - WDDM v2.0)"
    
    [ATI.Mfg.NTamd64.10.0]
    "%AMD6811.1%" = ati2mtag_R575, PCI\VEN_1002&DEV_6811&REV_00
    "%AMD6811.2%" = ati2mtag_R575, PCI\VEN_1002&DEV_6811&REV_81
    "%AMD6810.1%" = ati2mtag_R575, PCI\VEN_1002&DEV_6810&REV_00
    "%AMD6810.2%" = ati2mtag_R575, PCI\VEN_1002&DEV_6810&REV_81
    
    So R7 360/360X should be Pitcairn/Curacao (GCN 1.0):
    R9 270 == R7 360 == AMD6810 Pitcairn PRO
    R9 270X == R7 360X == AMD6811 Pitcairn XT

    R9 370/370X is probably Tonga:
    R9 285 == R9 370 == AMD692x Tonga PRO
    R9 M295X == R9 370X == AMD 693x Tonga XT (the iMac version with 2048 shaders)

    R9 380/380X is probably Hawaii:
    R9 290 == R9 380 == AMD67B0 Hawaii PRO
    R9 290X == R9 380X == AMD67B1 Hawaii XT

    R9 390/390X is obviously AMD7300 Fiji.

    R5 330/R7 340 could be Iceland AMD6902/6903, a new low-end GCN 1.2 part revealed in CodeXL 1.7 which would be a replacement for Oland.

    R7 350/350X could be Bonaire AMD6658/665D.

    So here is what I think the final 300-series desktop line-up should look like (based on my table of current GCN chips):

    Code:
    Pitcairn/Curacao
    (GCN 1.0, 2800 million gates, 212 mm2, 256 bit GDDR5)
    PRO 1024:64:32 - R7 360
    XT 1280:80:32 - R7 360X
    
    Tonga
    (GCN 1.2, 5000 million gates, 359 mm2, 256 bit GDDR5)
    PRO  1792:112:32  - R9 370
    XT  2048:128:32  - R9 370X
    
    Hawaii
    (GCN 1.1, 6200 million gates, 439 mm2, 512 bit GDDR5)
    PRO  2560:160:64  - R9 380
    XT  2816:176:64  - R9 380X
    
    Fiji
    (GCN 1.2, 8000+ million gates, 550+ mm2, 4096 bit HBM)
    PRO  3584:224:128  - R9 390
    XT  4096:256:128  - R9 390X
    
    Not really sure about the lower end... maybe Iceland will move down a few positions?
    Code:
    Iceland
    (GCN 1.2, ~1100 million gates, ~100 mm2, 128 bit GDDR5)
    PRO 320:20:8 - R5 310/320
    XT 384:24:8 - R5 330/340
    
    Bonaire
    (GCN 1.1, 2080 million gates, 160 mm2, 128 bit GDDR5)
    PRO  768:48:16 - R7 350
    XT  896:56:16 -  R7 350X

    Iceland is definitely a 6 CU VI chip - basically updated Mars/Oland. So, it can replace Oland, but can't fully replace Cape Verde even (not that I'm saying a chip there would really be needed), and of course it's very far away from Bonnaire. Should perform a lot better in any ddr3 configuration compared to Oland however thanks to fbc.
    I guess it's the chip of choice for those crossfire apu/discrete combos AMD is so fond of (for Carrizo). It would possibly make sense as some low end mobile chip (which are usually saddled with 128bit if not 64bit ddr3 memory), except that I fear it can't quite compete very well with GM108 there - the 128bit ddr3 interface should give it an advantage, but I'm worried about the perf/power side.

    Take it with a big big...huge...humongous even, pile of salt as the poster also posted this...

    So, it comes down to, how likely is it a 17 year old will have access to this and be posting about it? And if someone thinks perhaps his parents are the ones with access... How likely is it that someone who has access to this wouldn't be able to afford computer stuff (even hand me downs) for their kid?

    TBH, I don't even know what there is to take with a huge amount of salt. Is there any kind of information in that screenshot other than that AMD engineering samples of unknown ability exist?

    He also posted other stuff that people in here are talking about, or if they look at the reddit thread itself, some of the claims he is making.
