PCI-Express 4.0 Performance Scaling with Radeon RX 5700 XT @ TechPowerUp

Published: | Posted By:

With the launch of Zen 2 we also get our first look at PCI Express 4.0 and heaps more bandwidth.  The question is.  What can you use all that bandwidth for?

Games of course!

PCI-Express 4.0 has been one of the main new features prominently brandished on the product boxes of both the 3rd generation Ryzen desktop processors, and Radeon RX 5700 series graphics cards. We examine the performance impact of running these cards on older generations of PCIe.

A good indication that we have an increase in performance is to do an Apples to Apples test taking the faster component and using it with slower hardware.  That will give you a good benchmark to compare against and with how much faster PCI Express 4.0 is it would be interesting to see exactly how it will benefit you.
