    Using the same cooler what does the RTX 2080 (EOL) and RTX 2080 Super gain.

    Seems underhanded to only do one vendor but not the other.

    Why is that underhanded? They're testing to see if you can overclock the rx 5700xt to get gtx2080 stock performance.

    i9-9900K@4.9GHz.
    It's Shadow of the Tomb Raider, not Rise. I've given it one more try, BTW. The FPS gain is still within the 0–2 % range, considerably worse than any other game.

    The cost of the cooler increases the product cost and their comparison is against similarly priced products. IMO the review would have been more interesting to also compare OC's of similarly priced products.

    Because of the static comparison to the other vendor's product when it too would have improved performance with the same cooler.

    So it is and Apples to Oranges comparison.

    I haven't watched the video, but I think that for a comparative review to make sense, it has to be made at iso-something. It can be iso-price, iso-power, iso-performance, iso-noise, but some variable has to be the same on both sides, or you're just comparing things that can't be compared.

    So comparing GPU A + custom cooler with GPU B with default cooler makes sense if, for example, the price of GPU A+cooler is the same as that of GPU B alone. Then, you either compare both at stock settings, or you overclock both, to the extent that each GPU will let you. Obviously, GPU A's custom cooler may provide more headroom, but that's fair, because the overall price is still the same.

    The video is just an overclocking test to see if they can push the rx5700xt to rtx2080 performance with some kind of v-table modding. The end result is no, they can't. It's not a value comparison. It's just a test to see what overclocking results are possible. There's nothing deceptive or unfair about it.

    The video has this in it's title "Radeon RX 5700 XT Overclocked, RTX 2080-Like Performance"

    I'm looking for a review showcasing power draw for video playback, h.264, HEVC, Bluray etc, preferably with MadVR as video renderer. Reviews seem to skip this mostly now days. Any assistance would be appreciated!

    TechPowerUp alway tests power draw for media playback. Doesn’t fulfill all your criteria, but still.

    Found that computerbase and pcgh has 4k 60fps wattage:
    https://www.computerbase.de/2019-07...st/3/#abschnitt_messung_der_leistungsaufnahme
    https://www.pcgameshardware.de/Rade...ase-Benchmark-Preis-Kaufen-Vega-64-1293229/4/
    https://www.techpowerup.com/review/amd-radeon-rx-5700-xt/31.html

    Techpowerup doesn't list settings for media playback but it's lower then above. Which probably means something not as demanding, FullHD 60 fps, 4k 30 fps? Anyway the results are good.

    I guess MadVR power draw has to be derived from game (3d) Watt draw for now, since most of what it does are shader related.

    When you let the hardware cull rather than compute all parts are faster. That says you can't conclude anything about primitive shader culling from this experiment. Performance characteristics have seemingly changed since the developer made the recommendation to enable GPU culling (compute) on AMD hardware.

    TechSpot tested performance of the 5700XT with a EK water block at 2.1 Ghz. I'd expect the AIB custom models performance to be somewhere between reference 5700XT models and the tested water block versions using Igor's Lab method to bypass frequency limits.

    I already pushed my Vega over 340w, 258w is nothing :evil:

    So if I got this right: Navi is basically a unfucked version of Vega on 7nm, with working Primitive Shaders, or am I talking BS?

    There is a Navi architecture thread that goes into more detail on what has changed. There are more substantial changes than primitive shaders and fixes to unspecified Vega issues.
