Another set of benchmark tests have popped up showing the R9 290X performance when Crossfired. He was lucky to get his hands on not one but two R9 290X’s hooked up in crossfire and tested them out on the 4K GPU killing resolution.
According to the above images we can see that the R9 290X when crossfired gives the performance of almost twice that of the single card, meaning scaling for this card is a home run for AMD (85%+).
For smooth gameplay you do not want to dip below 30FPS (competitive gamers may feel the lag), which the R9 290X alone was capable of , when crossfired the framerate hit 60FPS all at a 4K resolution. Its dream like performance to play Crysis 3, Battlefield 3, Tomb Raider all maxed out at 8.3 megapixels @ 60fps. There were still a few games like Hitman Absolution, Max Payne 3 and Shogun which were unplayable, that might just be an optimization issue or beta drivers, but we don’t want to get into that debate for now.
Leaving the crossfire matter aside, we managed to check out the comparison chart of the R9 290X (Uber Mode) vs R9 290X (Silent Mode) vs GTX 780. The weird part is not how the R9 290X performance is better then the GTX 780, but it’s how both modes of the R9 290X have almost similar performance. Both the modes have a slight difference of 1 or 2 fps and at some places even decimal differences. This sure is a strange thing we have to check out in the future, it may be a safe-way of OCing on the GPU that AMD developed and the card only overclocks itself when needed (Nvidia GPU Boost anyone?).
In the end, all we can say is that the R9 290X is the card we can get for “quite” a future-proof setup, but we are still not sure as Nvidia have announced their GTX 780 Ti (12GB GDDR5 ?). The R9 290X launch remains a mystery while the GTX 780 Ti will be available next month.
