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%.
