    We were just speculation on the reasons why AMD would chose to not show a "bigger' Polaris chip in their presentation :wink:

    They can do that afterwards too, just issue a statement saying we are now giving rebates. It doesn't detract from the 1070 at all.

    You are trying to make the case that this rx480 line is like 48xx line, I don't put faith in that, because of how AMD has been marketing these cards. There was a fast response with the 48xx line if I remember correctly and it was literally half the die size or close to it to the competing cards.

    One point I haven't seen mentioned here, in theory FINFETs achieve higher frequencies at higher temperatures as opposed to traditional planar transistors. They are sort of weird in that way, so it's possible higher operating temps with the temperature stability of a water cooler could yield interesting results. A chip maintaining 80C (or more) and dissipating a lot of heat may get very interesting results.

    If dreams is what you want for, $300 card will be RX480 All-in-Wonder Pro. New and improved product for the new Twitch-streaming age. :)
    I would actually want this, built-in HDMI PASS-THROUGH so that I can record HQ footage from my PS4

    I would not want to pay $100 more for just $10-15 faster performance. If all goes well, RX480 will be able to be overclocked that much.

    For the record in this vid Raja kinda slips out 'less than 150W'


    I'm inclined to doubt they are all that far under.
    Saying 150W if they could have quoted something more like 'just over 100W' just opened them up to looking bad in perf/W vs the faster, also 150W 1070.
    But I'd be happy to be wrong.

    Nothing new. Just a general overview of entire Computex announcements and speculation about EU pricing, journalist were not allowed to see the rendering settings for the game [it was rendered at 1080p though].

    That includes the memory controllers and they're a go
    od part of it. At any rate, a 4 GiByte version would also need the same number of chips (hopefully!), which should reduce possible power savings from memory size further. All in all, I doubt that that's a large factor.

    I can't find a lot of breakdown data but according to this memory alone accounts for anything from 22 to 35% and memory controller from 16 to 26%.

    I'm sure there's some info listed how much actual memory modules consume?

    I remembered wrong.
    Here's what AMD measured on R9 290X (http://www.amd.com/Documents/High-Bandwidth-Memory-HBM.pdf)
    "1. Testing conducted by AMD engineering on the AMD Radeon™ R9 290X GPU vs. an HBM-based device. Data obtained through isolated direct measurement of GDDR5 and HBM power delivery rails at full memory utilization. Power eciency calculated as GB/s of bandwidth delivered per watt of power consumed. AMD Radeon™ R9 290X (10.66 GB/s bandwidth per watt)"

    Which equates to 30 watts for the memory chips alone.

    Can't find any reviews of 2GB vs 4GB or 4GB vs 8GB of the same card with power consumption tests included, but for what it's worth, 4GB factory OC'd custom GTX 760 consumes only 11 watts more than reference 2GB GTX 760 (http://www.legitreviews.com/gigabyte-geforce-gtx-760-4gb-video-card-review-2gb-4gb_129062/5)

    In the review you linked it doesn't work correctly on either one

    To not mention it makes no sense to compare a task scheduler (ACE) that decides when and in which CU to dispatch and execute a whole program with an instruction scheduler (Fermi) that decides when to schedule single instructions on the same SM. It's so funny when people things the lack of the latter Fermi-like scheduler impacts DX12 support when it has absolutely nothing to do with it.

    It seems some people do not realize that there are tons of different shedullers, work distributors and other logic in GPU. It's funny how some of them consistently tend to misinterpret the things just because they've heard somewhere that there is a lack of "hardware scheduler"

    My response was moved to the other thread but it does perform better on Nvidia by a fair amount with Chapter 2.
    So if you still want to debate why Hitman is not a good example of DX12 its best to take it over there.
    Cheers

    C993 is unknown (wccftech C99 is flagship)
    D009 seems like RX 480
