AMD recently announced its hardware partners could start offering their own versions of the Radeon R9 290X with 8GB memory. Sapphire was the first (and as of yet the only) to be able to offer us a 290X with 8GB memory, namely the Sapphire Radeon R9 290X Vapor-X. We put the graphics card to the test and compared it to the 4GB edition to find out whether the added 4GB has a sizeable impact or not.
If you’re not quite familiar with the Radeon R9 290X you can read all about it in our initial review. The popularity of the R9 290X has decreased somewhat with the recent introduction of the Nvidia GeForce GTX 970. Our tests have revealed that the cards are not only well matched in terms of specs, but they are also priced competitively. The decision between Nvidia and AMD will depend mostly on specific things; AMD flaunts their FreeSync support, the Mantle API and True Audio while Nvidia banks on support for G-Sync and lower power consumption.
