AMD RX580 & 570 Strike Back
A long time ago in a fabrication
plant. FAR FAR Away well actually it wasn't that far away and it was in June of
2016 that AMD Drop(x3) the RX 480. Codename Polaris in a wild marketing campaign
evoking revolution and for a good reason the 400 series performed really well
for the price. Although the flagship 480 was quickly overshadowed by Nvidia's 1060.
Haha the dangers of shooting first. But after 10 months of reloading AMD is finally
ready to fire again with the only question being, what's in the Chamber
Firepower or FIRE POOR! Come on. It's okay. maybe it's not funny but it's silly
so let's get this out of the way this is still Polaris the same architecture
AMD use for their RX 400 series if you were waiting for AMD's highly
anticipated Vega GPUs then you'll be disappointed.
BUT if you were waiting for
Polaris enhanced with a more mature 14 nanometer FinFET process and tighter
voltage and frequency regulation translating into better power efficiency and
higher clock speeds then you and all the other holdouts with R9 285 or R9 380s
should be amped as hell Right about now. Well hold on a second here, Linus. Is
this just a shinier 480 Why is this even worth a video and where is VEGA?!? Great
question. RX 570 and 580 then presumably due to slumping RX 480 4GB sales AMD'
these partners will be putting more emphasis on the top tier 8GB version this
time around though that won't have much of an impact on you the consumer and
pricing looks to be well basically the same with RX 570 coming in ten dollars
cheaper on average than the 480 edit replaces in other news AMD's slide deck
also had prominent mentions of both the RX 550 AND RX 560. the former but of
which is brand new silicon.
But we don't have those yet so all we can say for
now is that apparently the RX 550 is better than an integrated GPU at 80$ And I
would sure as hell hope so and the 560 is a 460 but with a ten dollar price
drop and since enthusiasts were running around unlocking extra compute units
with bios tricks AMD went ahead and enabled those right out of the factory and
I guess there's some software news as well as of the RX 500 series launch AMD's
radeon driver for every card from 7000 series onward includes what they're
calling Radeon chill a configurable frame limiter that improves thermals and
power draw when enabled you can specify a minimum and maximum frame rate and radeon
chill will keep your game running within that window eSports titles for instance
are designed to be easy to run and for that reason they're notorious for ultra
high frame rates that go way beyond what a typical or even very high-end
monitor would be able to display so what this translates to for users is lower
noise and more consistent performance without adding any input lag and in some
cases they claim even improving it pretty cool right.
Yeah call me
when it's in a notebook you guys also a bigger supported games list would be swell
so to AMD's credit the big eSports titles are mostly covered here alright Ben
Linus enough stalling tell us how they are X 580 and 570 perform you guys are
so demanding sometimes you know okay so we tested our shiny new cards on both our
Intel test bench and our Ryzen AMD test bench along with equivalent last gen
cards from both AMD and NVIDIA now since AMD doesn't have reference boards for
the 500 series they actually sent us factory overclocked cards to test so shout-out
to asus nvidia who provided us with some factory overclocked cards for the
greenside to level the playing field somewhat before you ask by the way we did
try overclocking these cards further but neither of them achieved a core overclock
of more than 50 megahertz over what they already shipped with so then as we can
see in our performance testing obvious things are indeed obvious in fact we've
got a measurable if not earth shattering performance bump over the RX 400
series DirectX12 and Vulkan both show us a wider improvement than DirectX11
thanks to those APIs more efficient rendering pipelines that favor AMD's GCN
architecture although again the difference isn't that massive and also of note
here is the utterly uninteresting differences in performance between the cards
across Intel and AMD CPU platform so.
Sorry conspiracy theorists but the rumors
of NVIDIA's drivers crippling rise and performance seem to have been greatly
exaggerated. So the TL:DR then is that in a big surprise to no one we're
looking at a higher clocked our RX 480 and 470 for this release AMD chose to
iterate on their existing polaris architecture cards in order to address some
of their short comings against Nvidia's mid-range and budget line up. Have they
achieved that? Well as far as performance is concerned yes yes they have when
it comes to power consumption the story does fall apart a little bit
particularly with these factory overclocked cards though it should be noted
that we didn't use Radeon chill for our testing because it makes apples-to-apples
comparisons go sour so then if you're an AMD fan desperately waiting to upgrade
your high-end Hawaii or Fiji based GPU then you get to keep waiting but if
you're more of a mid-range buyer who didn't know enough lawns last summer for a
470 or a 480 then great news because you get a little bit more for your money
this year so rock on you sexy gardening beast you.
