Conclusion
Having a quick look at the results shows, the advantages towards the GTX 980 Ti are overall moderate. At FullHD the GTX 980 Ti is on average 9% quicker than the FuryX and at 1440p and 2160p (UHD) the difference is 4% and 3%, respectively. Averaging the three resolution values results in a 5.5% advantage towards the GTX 980 Ti, which is basically not visible. It's also interesting to observe that at FullHD the gap between the GTX 980 Ti and the FuryX is a bit bigger than at UHD. Apparently the AMD card is becoming stronger the higher the resolution and detail levels are, which is the case due to the extremely well performing HBM (High Bandwidth Memory) memory. It's just a pity the FuryX doesn't feature more than 4GB of VRAM, while the GTX 980 Ti has 6GB to offer.
It's also interesting to compare the power consumption of these two cards. In this case the GTX 980 Ti burns less power in idle as well as under load. In idle the system with GTX 980 Ti pulls 8 Watt less from the wall than the FuryX (70W vs. 78W). Comparing the load values, then there is a significant difference, since the system with GTX 980 Ti pulls 321W compared to 405W looking at the figures with FuryX. Bottom line the GTX 980 Ti is more energy efficient.
For now we've had a look at the performance, which means it's about time to consider the price. These days the NVIDIA GeForce GTX 980 Ti sells for 697 Euro and the AMD Radeon R9 FuryX costs 573 Euro. In other words this means, that the GTX 980 Ti is almost 22% more expensive, while at the same time performing on average 5.5% better. It appears we're coming to the usual conclusion when directly comparing NVIDIA and AMD cards, which address similar customers. NVIDIA is more expensive and offers better energy efficiency, whereas AMD offers a very compelling price point but less convincing energy efficiency. Apart from that NVIDIA scores in terms of how much VRAM you get.
