Does PCIe 4.0 help the RX 5700 series?
Here We will test a few of our benchmark suite to see if there is any real difference in performance being on the new PXIe 4.0 X570 Platform.

Shadow Of The Tomb Raider
Now we’re getting into the territory of a game more optimized for the higher performance GPUs. Shadow of the Tomb Raider is an awesome game and part of a long lasting franchise. It supports full DX12 along with new RTX features which we may start to include in testing once Radeon options have ray tracing capabilities enabled. We run at max details at DX12 with RTX and DLSS disabled.
First up is an actual game. Shadow of the Tomb Raider shows that any graphical performance swapping to PCIe 4.0 is within the margin for error at best. This tells me something that I suspected which is that the GPUs simply do not have enough bandwidth needs to show any performance gains at least at this time. I’m sure we will get there but time will tell as tech evolves.
3DMark Fire strike
3DMark Firestrike Ultra shows a gain for the RX 5700 while the RX 5700 XT actually lost some steam at PCIe 4.0. I can only assume this is standard testing variance at play and once again call it more proof in the pudding.
3DMark Time Spy
Time Spy Extreme is more of the same. The RX 5700 shows no change at all, with the exact same graphics score. The RX 5700 XT shows an extremely minor gain and within a close enough margin that I would not call it a reason to need PCIe 4.0 for these cards.
The numbers don’t lie, while it’s cool to have PCIe 4.0 on the platform, it simply will not net you much as far as GPU performance gains. SSD/Storage and other devices such as network and HBAs I could see a major advantage to the new interface. But You would be safe to grab an RX 5700 series for any of your current PCIe 3.0 based platforms and you will not suffer any measurable performance loss.
