TechPowerUp published Intel Arc A770 Tested with PCIe 3.0 and Resizable BAR Off
A quote from the article:
In this article we're testing the Intel Arc A770 graphics card running at PCI-Express 3.0, to get a feel for performance on older systems that don't have the PCIe Gen 4 capability. Another round of testing is done with PCIe Resizable Bar disabled, and finally we have benchmarks on Gen 3 with ReBaR off.Intel Arc A770 Tested with PCIe 3.0 and Resizable BAR Off
