I learned a few things, so thank you!
That Xena XMOS chip really is a dark horse. So much potential there... the blocking channels model it uses mirrors the channels in the go language.

Thanks for the reply, I hope Tabor could be socketed some day. Maybe it will have a more powerful chip soldered.

Thanks, always happy to make you laugh and then insulting me, it shows how clever you are.
I also tested WinUAE on a FX 9370 and on a i7. It's slow, period.
If you are satisfied with such a slow system (I mean AmigaOS 4.1 emulated), I'm ok with it but don't fool others with wrong arguments.
Show me your slow emulation (with 3D games, Blender, heavy sites, and so on) and I'll show you how my Sam440 goes faster than anything you'll try to demonstrate.
Of course, playing a bit with it is funny but using it on a daily basis (ok, I admit : with my X1000) is not at all the same thing.
Try to be honest, please. Ok, you managed to install OS4.1 under emulation, you're good. And then ?
PS : and even with a 10Ghz x86 (which could give gou decent speed indeed), you'll still be limited to 1GB RAM (with some trick), no 2D acceleration, no 3D acceleration and so on. _________________ PowerMac G5 2,7Ghz - 2GB - Radeon 9650 - MorphOS 3.14 AmigaONE X1000, 2GB, Sapphire Radeon HD 7700 FPGA Replay + DB 68060 at 85Mhz |

Nah, not true that you're restricted to 512MB for OS4 in Winuae. Odd choice of figures to be honest. There's NEVER been a 512MB limit. 128/256MB at 1st due to csppc/bppc limits, and then roughly 2Gig (which includes all address space), but never 512MB. |
In practice, 512 MB Z3 is the limit. 768 if you're very careful with other emulated peripherals taking up address space (network, Picasso IV etc.). AmigaOS 4 on Classic hardware (real or emulated) does not support Zorro expansion boards mapped above the first 1 GB of address space. Also, because it uses virtualized memory addresses, it needs to map all memory expansions into the heap, which is 768 MB of address space, shared with any other expansions, regular chip/PPC RAM etc..
AmigaOS 3.x does not have these limitations and does not use memory address virtualization, and can use up to 2 GB. AmigaOS 4 on modern hardware also does not have those restrictions.Last edited by AdvancedFollower on 06-Mar-2018 at 10:20 AM. Last edited by AdvancedFollower on 06-Mar-2018 at 10:17 AM.
