Yeah : ) AresOne with AmigaOS4 classic...

I can see a whole lot of benchmarks on the way. :)

Without PearPC JIT? That will be interesting.


604e 40 MHz class performance on my hardware.

@pavlor

im not really interested by amiga ppc emulation , but thinking no one had been advance the winuae autor to use the sheepshaver core and not the pearpc? just because sheepshaver is ppc jit?

For understand on my quad I7 2.3 ghz (2012)
Sheepshaver X86 have the half of the speed of Sheepshaver of it on Quad G5
and 1/3 compared Rosetta on Classic it means on my configuration will be like a G5 1.0 ghz speed on a I7 cpu

Sheepshaver CPU core was rejected because it does not have MMU support.

If speed will be reach a good G3 level this could be a major chance for OS4 or MorphOS. All ppl interested in MorphOS or OS4 wil have the chance to run/testdrive the OS with lowest hurdles (no expensive hw, no additional hw at all.

While I think OS4 is more in need of this, I would suggest the MorphOS team to embrace this new option (if speed will be remotely acceptable on average pc). Maybe just provide a 30 min eval version that cannot get registered to kep the distance on "real hardware" rewarding enough.

At least it yould help existing OS3/4/AROS/MorphOS developers maintaining/testing their projects on more members of the OS family.

WinUAE has some severe limitations:
128 MB RAM limit for CyberstormPPC board (OS4 supports ZIII RAM only as SWAP - that would be easy to change).
2D GFX only (no native 3D support or compositing). I don´t know if P96 UAE driver can be used with OS4 (Picasso IV emulation is limited to 4 MB GFX RAM).

LAN could be supported by A2065 emulation, so no problem there.


Even with above mentioned limitations, this emulation could be good introduction to the NG Amiga and best solution for portable OS4 computer.

Beta 11

With support for OS4 Classic.

Still no luck in runing Quake...

@pavlor

3D, compositing or more RAM is not so important if all you want to do is development or testing. So it could be useful testing/development envirinment.

However, MorphOS is only available in 1.4 version which is way too old.

Core i5-2500K 3.3 GHz.


Edit: Benchmarking is not really possible at this state of PowerPC emulation, 40 MHz 604e is more estimate than real value.

Toni stated in release notes for beta 11, that he will abandon PearPC CPU core in favor of QEMU (if possible and feasible in distant future...). How fast is PowerPC emulation in QEMU? I tried only i386 emulation (without KVM/virtualisation/accelleration) and I got cca 1/32 of native performance.

@pavlor
Don't know, so far i did it only the Opposite Way emulating i386 with qemu. Pearpc was better with jit for Running osx.

Would you say that it is useful in any way right now?
I ask because I would add AmigaOS 4 classic than as option in my shop.
The system would use a Intel Xeon E5-1620 3600MHz like the mac pro. (well I should just try my self : ) )

I just did HardInfo benchmarks in debian squeeze (PowerPC 750 emulated on Core i5-2500K 3.3 GHz; QEMU 2.1); lower is better except CPU CryptoHash:

CPU Blowfish- 73.35
CPU CryptoHash - 12.58
CPU Fibonacci - 31.52
CPU N-Queens - 76.83
FPU FFT - 189.67
FPU Raytracing - 449.50



For Comparison (from Debian Squeeze Hardinfo Benchmarks thread (post 1) )
Sam440ep-Flex 800 MHz

CPU Blowfish- 86.944
CPU CryptoHash -12.240
CPU Fibonacci -24.466
CPU N-Queens -64.646
FPU FFT - 88.107
FPU Raytracing -77.260


Conclusion: performance of QEMU PowerPC emulation on my PC is comparable to 440EP 800 MHz in integer applications, but much slower in FPU demanding tasks.

Too slow and non-compatible to be really useable (Beta 11). Better to wait for faster core (eg. QEMU).

@pavlor
Thanks, well this is not too impressive.. the XEON i mentioned is not too much faster compared to the i5.

The whole system would cost including OS4 960€. Ok if i remove the entry-quadro for a standard-gpu you you can save 120€. If i change SSD to standard HD.. and if I go from 16GB down to 4GB ...well than you get SAM440 performance for Sam(e) price...

Hmm.. Something for next year or the year thereafter. At least Toni deserves 1 or 2 donations for his work.

That is QEMU speed, not current WinUAE PowerPC emulation.

It would make sense in case of laptop (or other portable device).

@phoenixkonsole

Er no, because 1. Your not factoring th WinUAE emulation of hardware overhead and 2 the SAM has a much better gfx card (mostly like Radeon 9250 if a SAM flex) and dma accelaertaed access to that card.

We discussed simply QEMU CPU core performance, not future WinUAE implementation.

UAEGFX has fast 2D performance (however, there is no OS4 driver).
