At least in a gaming sense especially because of the new Mantle API. This is AMD’s game changer and if it does take off, it would make for a very interesting GPU landscape. The incentive from AMD’s perspective for doing this is sensible but how that works for us as end users remains to be seen. No matter how it’s spun, we have been here before in the mid to late 90s and this is no different in practice. That however is specifically to do with gaming which is primarily what this card is for. The absence of customised designs has left very little room for variance in overclocking 26 The OverClocker Issue 27 | 2013 between different vendor offerings. So essentially what we bring to you here is a reference card review of the AMD R9 290 GPU. The only difference here is that PowerColor has seen it fit to ship their card with a slight overclock, more specifically a 25MHz overclock. Everything else about the card though remains that which AMD showed off and has been providing to its other partners. A 25MHz overclock is not going to make a significant different in performance but having that at least would perhaps help separate the PowerColor card from the rest. Even better though or more meaningful than the slight overclock is how this particular card didn’t have a dynamic clock speed dependant on temperature. Load temperatures were very high at 94’C however the clock speed remained at 975MHz. This is great if only you’re guaranteed performance that matches that of the AMD press cards and because of the minute overclock the performance is actually better for the most part. Oddly enough, despite what we had read before purchasing our PowerColor sample for this review, this card remained relatively quiet. More so than we could have ever thought it would be. There simply wasn’t any noise while we tested the card and as stated earlier, the clock speeds remained consistent. It is only when we increased the fan speed from the default profile to anything above 60% where the noise levels became unbearable. Under normal circumstances though, there would be no need to do this despite the high load temperature. If the GPU is able to operate at that temperature and not result in decreased performance, then we see no need to set a higher fan speed. Overclocking will obviously require you to do so, but in a gaming context, this isn’t necessary at all given that you’re only ever going to get noise for it and nothing else. At $400, the closest card to this from NVIDIA would be the GTX 770, however it’s obvious that this GPU will not be able to compete with the R9 290, thus we had to instead compare it with the many custom GTX 780 cards on the market. In this particular case we compared it to the EVGA GTX 780 Classified. A GPU that, like many, features an out-the-box overclock, custom PCB, and cooler has
