DDR4 Memory Scaling Performance with Ryzen 7 2700X

[Apoptosis]

When AMD announced the new Ryzen 2000 Series processors along with the new X470 platform on April 19th, 2018 many might have missed that G.Skill released new Trident Z RGB and Sniper X DDR4 memory kits custom tailored for this platform. We test a kit with the same timings at 2400, 2666, 3000, 3200, 3466, 3600 and 3733MHz to see of the performance scales on a Ryzen 7 2700X CPU.

How much of a real-world improvement be for higher clock memory? When would a user notice the different? I just purchased 2400 memory, curious if I should return it and buy 3000+.

unless you are building a top of the line kick ass computer that will run the newest games at the highest 4k resolutions then you will not notice a difference.

High end tasks like editing 4k video, cad drawing, photoshop (with HUGE RAW photos), high end gaming, etc are the areas you would want to max the memory speed. I would get the lower speed myself.

How much is the price difference? If you are building a new Ryzen system and plan on sticking with it for a number of years I would most certainly return the 2400MHz kit for a 3200MHz kit. The last time I looked 3200MHz kits weren't too crazy expensive and you will see a noticeable difference on many applications. A 12.5% performance gain on Far Cry 5 at 1080P with normal image quality settings goes to show how much performance a 3200MHz kit will get over a 2400MHz kit.

One of the reasons memory speed is so important on AMD Ryzen processors is due to the fact that the Infinity Fabric, the high-bandwidth interconnect used to connect the CCXs is synced with the memory clock. Therefore changing the memory clock speed is a pretty big deal!

If you are on Ryzen 1000 I would suggest a 3200MHz kit and if you are on Ryzen 2000 then I would suggest a 3200-3466 kit.
