AMD RX 580 and RX 560 leak

RavenXXX2 said:
Nope that is 560, the 550 is even more cut down 460. This thing should be £50 tops, at near £100 do one.

The 560 is a fully unlocked 460, so 1024 cores, 64 Texture Units, higher clocks, and 16 CUs vs 14, and has an MSRP of $99.

The RX 460 has 896 cores; although yeah; sadly the 550 is more cut down. Darn silly move.

I just never really understand the GPU manufacturer rebrand.

It makes sense for AMD. These are cheaper to make, small performance improvement and most importantly free advertising. With all those reviews now AMD can show of the matured Polaris drivers performance which the initial 480 reviews did not have which made the 1060 look stronger to the uninformed. So yeah, many advantages for them.

For us as consumers, not too much. Better out of the box clocks maybe, potentially better coolers. But from what I can see the power consumption of Polaris has not improved at all. If one can get a 480 much cheaper, it would be worth getting that at this point.

I am a lot more interested in seeing how much improvements Vega architecture brings.

I know people have been saying GF 14nm is still unstable yields wise but this is a bit puzzling seeing as they are supposedly onto a better revision on the process (though no guarantee these Polaris cores are using it - could have been produced or already in production before hand).

There was a chart released last year which showed Polaris was optimal at between 900MHZ to 1000MHZ,and the Polaris derived PS4 PRO GPU is in that range. Look at the Polaris derived XBox Scorpio GPU - it is running at between 1100MHZ to 1200MHZ,so even if the optimal frequency range has increased,AMD has compensated by bumping up the clockspeeds another 100MHZ or more.

What is really needed is someone to test early production RX480 cards,late production RX480 cards and launch RX580 cards across a range of voltages and frequencies to see if anything has changed,but it would ideally have to be with similar AIB cards,or reference cards. IIRC,there is actually a reference RX580 but I suspect it will only be for pre-built PCs.

This is what I understood from a Raja interview last year. Polaris is not exactly optimal for desktop and high clocks. But Vega will be, as it is built for desktops and high performance. Hence why I never understood why people kept looking at 480 and saying AMD will be lucky to make the leap to a 1070 or some crap like that. Just showed lack of understanding.

Yes, that's the other puzzling thing. Faster memory would have had a negligible effect in terms of power (obviously a higher BOM of course) since Polaris seems to like the extra bandwidth. CB did a test at 4000 vs 4500 memory (+12.5%) and got 6% extra performance.

And that was just the slider; AMD adding faster memory would probably have involved new timings so potentially more than that.

Just to note the 1060 'Tip' (note the 'p') was tongue-in-cheek. But yes, AMD really should have pushed for higher memory and higher cores to make the 1060 not even being a choice in the market. PLUS.... there is such a massive performance distance to the likes of the 1070, they really should have closed that gap.

I didn't sell my 1070 to fund a card that doesn't even come close in performance for the same amount (320 for the Asus Strix is utterly absurd.)

Yeah sadly it seems to be Gigabytes turn to drop the ball with their AMD gpu's,
It's only fair though It was MSI and Asus's turns last time :D

ran hot as it was the only one to cool all 3 components properly :D but yes should have been a bigger heatsink design .

reason 580 Aorus have more and larger heatpipes along with the Extreme featuring 100mm fans .

same VRMs havent been recorded for 480 and 580 reviews :( least now with the new Unigene benchmark , ASUS, MSI, Aorus, Gigabyte, XFX & Sapphire can be put to the test to see how they do in the cool down test :D

I mentioned it yesterday but officially (according to Samsung and GF) the newer process has reduced deployment costs, it hasn't done anything to power or performance. Samsung and Gf are focusing on 10nm.

I'm not 100% sure about that exact sample, but the first few reviews on our RX480 were on a terrible BIOS that AMD provided.
This BIOS was so bad at load balancing that it overspecc'ed power drain from the PCI-e, this was fixed later. The RX480 sold to the channel never had this issue.
You can take my word for it, or wait for the RX580 reviews to come out.

need to start cherry picking and loading custom ROMs without telling anyone :D
