Kaapstad, I am member of the
AMD Reddit Discord server. Even being from the UK myself they are (generally

) a lovely bunch.
I have lots of FireStrike benchmarks to post with you all on their behalf, so here goes. The formatting is Discord name (Reddit username), so:
Dan (Railmoth) got this [will fix in the morning].
Furthermore, @Brice Walker's result is
this--not verified due to piracy so screenshotted by him instead--and @MelancholyWay posted
this from a user I do not have a FS benchmark link to yet.
Lastly, we have @brutuscat2's benchmark
here.
I'm sure you're all aware of
this and
this, and the conclusion from Dan (Railmoth) and Brice Walker and brutuscat2 (all owners of RX 480s; @Brice Walker's actually from Reddit's AMA giveaway), our conclusion is identical to AMD's:
that's all which can be done with the reference RX 480, and compatibility mode is there too as a backup. Therefore, the only hope of a better performing card is to wait for OcUK's Nitro+ OC orders, or other custom AIBs.
These conclusions have also been echoed by Jim from AdoredTV in
this,
this and
this video, and
PCWorld verifies and validates this also.
