    You guys realise that by doing that (releasing the consumer product with HBM2) they would basically double the development costs for the consumer drivers right?
    I mean e.g. double the amount of tests, different paths in the driver depending on the memory type, different optimisations etc.
    As much as I like the idea with HBM2 I will first believe it when I see it... unfortunately.

    Update from Patrick Schur >
    "
    - Max. TGP of Navi 21 XT is 290 W.
    - AIB partners are testing different TGP for their cards.
    - The ~2.4 GHz was achieved with an AIB partner card.
    So assume that the card was slightly overclocked.

    "
    [Update Navi21]

    Navi21 XL
    > Base clock 1350MHz to 1400MHz
    > Game clock 1800MHz to 1900MHz
    > Boost clock 2100MHz (maybe 2200MHz)

    Navi21 XT
    > Base clock 1450MHz to 1500MHz
    > Game clock 2000MHz to 2100MHz
    > Boost clock 2200MHz to 2400MHz
    "
    https://twitter.com/_rogame/status/1317731737347248129?ref_src=twsrc^tfw

    That leaves the XTX as an unknown and also XLE.
    Navi 21 XTX (0x731F:D0)
    Navi 21 XT (0x731F:D1)
    Navi 21 XL (0x731F:D3)
    Navi 21 XLE (0x731F:DF)

    I assume that the XTX (the special edition) will have game clocks cranked up up to 2.3-2.4 GHz and boost maybe 2.5.
    Remember ---- 2.4 was achieved by an AIB.... and AMD is keeping the highest SKU verrrrry close to the chest this time.... I even speculate that they are producing in on their own and AIBs are slapping only a sticker (similar as with my VEGA64 Liquid Cooled Edition).
    It would be interesting if AMD teased the performance of the smallest big navi having 3 additional aces in their sleeves :p:D

    Sounds like AMD might have a beast of a card.

    12gb-2.5ghz game clock navi22 for me. :p If priced at something like 400$ it will turn the market upside dawn.

    Just as a hint -- remember what they said in regard of RDNA2 :

    AMD's Radeon Product Management Lead, Mithun Chandrasekhar:
    “Similar to Ryzen,” he says, “all of us need a thriving Radeon GPU ecosystem. So, are we going after 4K, and going to similarly disrupt 4K? Absolutely, you can count on that. But that’s all I can say right now.”

    Been watching this thread for a while. Looks very promising.

    I have a 2070S but could see an upgrade next year depending on how things shake out.

    My last Radeon was the 7900 series.

    Haven't had an all AMD build since Phenom days. Nice to see the great competition for pc hardware once again!

    The fact 3070's are 8gb and was thinking of a 4k screen now has made this gpu def more interesting! I mean people are saying you prob need a 3080 for 4k anyways but dont like the fact nvidia are almost forcing me to get a 3080 because of the extra 2gb vram.

    Well.... 12 GB should be just enough for 2-3 years of 4k gaming....
    But even with memory compression the 10GB of an "old" 3080 (cause we already know "new" 20GB is coming for like 150-200 $ more) might be somewhat tight.... I mean I already saw one or two game examples, where in 4k + ultra textures we have topped at slightly under 10GB.... Of course you can't tell if the game engine is only reserving the memory or actively using it... with one exception I think.... where NV compared 3080 to 2080 (non Ti with 8 GB of RAM) in one of the Doom games (eternal ? not sure). Where you saw the framedrop due to exhaustion of RAM on the 2080.

    Plus don't forget that AMD also has memory compression... Not that good as NV but still within 10-20% margin.

    It will be a veeeery interesting fight - that I can tell!

    The thing and am sure its been suggested already in discussions why cut the 3070's mem and also the cores does seem like an underhand trick to put people off getting the 3070 for 4k use or maybe my tin foil hat has fallen off.

    Maybe was wishfull thinking the 3070 was gonna cut it anyways.

    Yeah... my spider sense was also tingling that is why I have eventually cancelled the preorder for the 10GB 3080 EAGLE OC that I have been able to "buy" for the MSRP price (699 EUR + shipping). I fear that I would face the RAM bottleneck sooner rather than later on 3080 + my C49RG90.....
    And on top of that - the paper launch.... must be fate that I will buy something from AMD again, if the Perf is ok (3080-ish +5% level would make me happy as an "acceptable" one) .

    Actually, AMD's memory compression is better now. Shaders can process textures in compressed state for some time. And that applies for small chunks of compressed data too.
    Each has different advantages. And if maximum compression is not needed due to sufficient amount of VRAM (which is true for any 8GB VRAM card), bandwidth matters.
    And that means Infinity Cache (as long as real) will tackle bandwidth side of things a lot and again puts limits of memory subsystem to rest.

    In general, I say that cards are more often than not limited by memory bandwidth than memory capacity. And it looks like RDNA2 focused on both. And that it improves on many different things. It may happen that jump from GCN to RDNA1 will prove to be smaller than jump from RDNA1 to RDNA2.

    Interesting. :)
    https://www.reddit.com/r/Amd/comments/jechk0/xt_is_full_die_for_navi_21_so_what_is_xtx/

    Even more so for some of the responses on the 6900 XT and 6900 XTX details.

    Im still holding on to my own Leaks:

    BigNavi XTX will have HBM2 (2x8GB) -> 749€ (maby less cuz' of 3080 performance)*
    6900/6800/6700 will rock GDDR6 18GB/s -> those SKUs will shake the market with very agro pricing.

    6900XT 499-549€ (min. 15% faster than 2080Ti)
    6800X 399€
    6700XL 249-299€

    * One guy from ATI (Canada) hint me that LC version is possible (4 months ago ;))
    So we will have Halo product like FuryX & Vega XTX LC

    I still hope they have showed a lower SKU and the bigger SKU will outperform 3080.
    But HBM2 ? Daaaaamn, I take two of those, where do I sign? :D

    There wont be hbm2 gaming card guys stop dreaming. I though that was pretty much confirmed.

    HBM is not important if IC works. My optimal GPU now would be 64CUs + 10x 1GB @18Gbps and maximum GPU clock.
    Cost efficient, energy efficient as much as I OC or UV. But with IC in play, memory part of desired card could as well have 8x 2GB @18Gbps.
    (But in that case large portion of VRAM will serve only as cache. And that portion would be 6.4~8.0GB for 60fps target. 10.5~12GB for 120fps target.)

    And that can prove to be big no-no for me. Sure, card with working IC and lower memory bandwidth would still have very strong and stable bottom fps line. But would not be able to achieve very high fps when very high resolution textures are in play.

    Good for average player aiming for 60fps+ even on 1440p. Bad for those who aim for 120fps+.
