The strange is the 5020 2ghz in all emulators been tested by me is comparable with a 970MP 2.7 ghz in speed and benchmarks but im facing the half of performance in i386-soft-mmu compared with a 2.5 ghz 970MP. I'm triaging old bugs: Can you provide command lines, versions, and steps to test and measure the relative performance? At the very least, please try to confirm on the latest version of QEMU (5.2.0-rc0, if possible) to update this report. [Expired for QEMU because there has been no activity for 60 days.]
