WinUAE only emulates classic Amigas with PowerPC cards. Unfortunately only A1200 & A4000 can be emulated with PowerPC cards and unfortunately this is not stable. With QEmu AmigaOS 4.1 runs faster and more stable and can use up to 2GB memory.

WinUAE 5.3.1's AmigaOS4.1 FE UP2 seems to be stable on my setup.

On Ryzen 5 7600X via AmigaOS 4's Dhrystone benchmark version 2.1 from
https://aminet.net/package/util/cli/WhetDhryStone


WinUAE 5.3.1's AmigaOS4.1 FE UP2 classic with GREX PCI / 3DFX Voodoo 3 and 1.2 GB RAM, has 3D acceleration via 3DFX Voodoo 3:
Dhrystone per Second: 1,823,260.6
Dhrystone MIPS: 1037


QEMU9's AmigaOS4.1 FE UP2 SAM460ex with sm501 and 2GB RAM:
Dhrystone per Second: 1,898,641.9
Dhrystone MIPS: 1080
