AMD Radeon RX 580 Overclocking and Benchmarks Surface

Some photos, screenshots and benchmarks of what appears to be an XFX RX 580 graphics card are doing the rounds, courtesy of overclocker Lau Kin Lam, who shared them (alongside a three-hour log video) on his Facebook page. Apparently, this is a special, China-only edition of the card, which is a shame, considering the great-looking waterblock that is smiling for the camera. The fact that this card is using a reference board with one 8-pin power connector may prove relevant to its overclocking efforts (and those of other, non-reference boards that we've seen carry both the 8-pin and an extra 6-pin power connector.
As to the results, these are completely as expected of a Polaris chip clocked at both the stock RX 580 clocks (1360 MHz) and overclocked to a respectable 1480 MHz. There is apparently a power bug that brings overclocking efforts past the 1500 MHz+ barrier straight against a figurative wall, hindering extra performance gains - this is expected to be resolved soon rather than later. Lau Kin Lam reflected this on his comment, alluding to the fact that the 1480 MHz (120 MHz+) overclock was achieved with a measly 12 mV increase to stock voltage, while a hefty 100 mV increase was required to sustain 1500 MHz clocks - and unreliably at that. Actual 3D Mark TimeSpy score increase from overclocking (1360 MHz to 1480 MHz, 8% increase) was around 6%.

Actual average FPS on Tom Clancy's The Division on very High settings @ 1080p stand at 61.8 FPS, with Rainbow Six averaging 136.7 FPS on the same settings.

7.5% GPU clock increase and 8% overclock headroom vs 5% on RX480, not too bad.
I wish they used fast memory on it though.
I don't think it deserves new model number, maybe rx480xt lol.
Hopefully will draw the price on rx480 even lower.

it should be named RX481, or RX485 at most.

That refresh of Polaris 10 will help those who just need a 480 to get it cheaper in destocking policy of sellers and will be good for those in need of a great GPU for 1080P@60-100Hz monitors while liking oc. Especially the ones with 6&8-pin power connectors will be very possible to get up to 1550 or higher imho. And this will be great value for this lvl of price too. I hope @W1zzard has something ready for tomorrow. Maybe a custom one with 2 pcie power connectors on the pcb? ;)

In Rainbow Six Siege, if the settings are the same @W1zzard tests in his GPU reviews, we can see that the increase in FPS is totally linear between a stock RX480@1250MHz (it throttles to lower clocks than that tbh) and this RX580@1580MHz. If true, we are talking about big improvements.



As for the name, many of us were waiting for a higher clocked P10 since the launch to be named as RX485, but marketeers liked RX580 better. That's honestly nothing to bother with if performance and VFM are even better then with RX480 eh?

And AMD wasn't to blame with poor power consumption and not very high clocks of the original P10 also, as the arch is not a high-clock hater (there were even RX480 that reached 1500MHz last year on water afterall). GF messed it again and after a year or so, engineering process matured enough to allow Polaris to show its abilities. I 'd like it even more though if they used faster VRAM to not constrain Polaris power as some benchmarks show about RX480 when VRAM gets oced. My 5 cents.

Nice, good increase in overclocking capability over rx 480 and can anyone elaborate on this part?..

There is apparently a power bug that brings overclocking efforts past the 1500 MHz+ barrier straight against a figurative wall, hindering extra performance gains - this is expected to be resolved soon rather than later.

Resolved by who? Driver fix perhaps? Would be nice if that is the case and these will oc to 1500+ though 1480 is very respectable imo and I'll be grabbing a 580 very soon :clap:

My opinion on this restraint is that maybe the 8-pin allow only this much of an oc without a special bios (like RX480) and only the 6&8-pin custom models will go beyond that having already the proper bios for it.

I'm just waiting for a decent price cut on the good, existing 1080p cards.

This being said most of today GPUs have way more power delivery than they need, so when you see these aftermarket cards adding even more power its pointless.

I'd still wait for Vega before deciding which card to go with.
And hell, I game on a notebook... :S

where the hell are my stars
So they hit the same clockspeed I hit with my 480's on air and took more voltage to do it?
