AMD's fastest GPU reviewed by ModCrash!
I’ve had my AMD Radeon HD 7990 for awhile now and it wasn’t until Mantle came out with the AMD Catalyst 14.1 beta drivers did I really want to take it for a test drive. Equipped with the new beta drivers and wanting to see how far I could push my GPU I started doing the testing. Now this review is way off from when the Radeon HD 7990 first debuted. While depending on the game you are playing, the AMD Radeon HD 7990 is the fastest single card on the market. With Mantle it just will further help AMD and keep my GPU on top until a NVIDIA 790 or dual 290X card comes to market. I have used this GPU to play old games, new games, and even tested to see how well it could mine cryptocurrencies. The AMD Radeon HD 7990 used for the testing is the reference model designed by AMD. For the benchmarks and test I left the Radeon HD 7990 at factory clock speeds as well as the other components in the test system. The HD 7990 handled everything I threw at it from stress test to playing on ultra settings in Battlefield 4. When watching the actually testing going I could see frame rates dipping into the single digits but only for a second. While 99% of the time everything ran pretty smooth I did encounter a couple issues. The first being artifacts in game and random freezing. I assume both of these issues are from the Catalyst 14.1 beta drivers.
