We re­cently did in-depth test­ing of AMD’s Ryzen 5 and 7 chips, so mim­icked our tests for these CPUs as closely as pos­si­ble, right down to the driver ver­sion. The meant we used the same SSDs, Bal­lis­tix me­mory, though we did have to change the cooler to fit the larger socket. Our test GPU was the Aorus GeForce GTX 1080 OC, and we set all game tests to the low­est res­o­lu­tions to en­sure the GPU wasn’t the bot­tle­neck.

Look­ing at the re­sults, it’s ob­vi­ous that the i9-7900X is a mon­ster, tak­ing out the top spot in nearly ev­ery test. We were es­pe­cially sur­prised at its gam­ing re­sults, where the slower fre­quency should have seen it per­form slower than the i7-7700K. It’s ob­vi­ous the ar­chi­tec­tural im­prove­ments have made a dif­fer­ence to per­for­mance.

As for the i7-7740X, this was less than im­pres­sive, ba­si­cally equalling the i7-7700K in most tests. There’s not much point in up­grad­ing to the i7-7740X right now, un­less you plan to climb the Core-X lad­der fur­ther down the road.

When test­ing the motherboards, we in­stalled the over­clock­ing soft­ware that came with each board, but as you’ll see the vast ma­jor­ity of these did not work, likely due to the is­sues with Turbo Boost Max 3.0. We’re sure speeds of 4.8GHz and above should be pos­si­ble with man­ual over­clocks.
