Gigabyte Aorus RTX 2080 Xtreme 8G Review

Rating: 6.5.

Our first aftermarket RTX 2080 review was the Gigabyte Gaming OC model which was essentially a triple-fan cooler on top of a reference PCB. Gigabyte’s Aorus brand, however, is known for delivering feature-rich custom cards, and this is certainly the case with the RTX 2080 Xtreme 8G we are looking at today. It’s one of the most expensive 2080s currently going, though, with a price of £899 here in the UK. Can it justify the extra £150 over Nvidia’s Founders Edition?

For £899, it is safe to say Aorus is delivering a number of interesting features that it will hope justifies the extra expense for its RTX 2080 Xtreme 8G. For one, the card comes factory overclocked to 1890MHz – the joint fastest out of the box clock speed we have seen so far – while it also boasts a whopping 12+2 power phase design. On top of that its RGB implementation is quite unique, while there are a total of seven display outputs as well – two more than usual.

With the same number of CUDA cores (2944), Tensor cores (368) and RT cores (46) as any other RTX 2080, what helps differentiate this Xtreme edition is its 1890MHz boost clock, which is the joint fastest we have seen – tied with the Palit GameRock Premium.

This Aorus card, however, is the first we have seen to ship with overclocked memory – 14140MHz instead of the default 14000MHz. With both of these increased clock speeds, it will be interesting to see how the real-world performance compares to the other RTX 2080 cards we have seen so far.
