AIB Cards, Temps & Clocks
Ahead of this launch, we ended up with half a dozen AIB cards, so we're going to look at the peak GPU hotspot temperature after half an hour of gameplay in an enclosed ATX case (we used the Corsair Obsidian 500D). This is stock, out of the box performance as I didn't have time for noise normalized testing, dialing in each card takes quite a bit of time.
The highest clocking models were the Gigabyte Gaming OC and XFX Speedster Merc 319 and of the two, the XFX was far more impressive, operating its fans at just 1000 RPM for a hotspot temperature of 85C. The Gigabyte model was 2 degrees cooler, but you're looking at almost twice the fan speed which increases the operating volume quite drastically. The Gaming OC should be a fair bit cheaper though, so it could still represent better value.
The PowerColor Red Devil and Hellhound models were very impressive, both ran the fans at 1000 RPM for sub 80C temperatures. The Red Devil clocked around 100 MHz higher and that made it one of the best models we tested.
Sapphire's Nitro+ almost forgot it had fans, spinning them at just 800 RPM after 30 mins of load. This model also appeared to sip power despite running the cores at 2.5 GHz. The hotspot temp creeped up to 91C, though that's not bad given the whisper quiet fan speed.
The MSI Gaming X was one of the least impressive models and we suspect it would be comparable to the Gigabyte Gaming OC under noise normalized test conditions. It was quite a bit better than the AMD reference design though, so there's that.
