Note i wrote before Xeno is using Qemu on linux and is much better compared Qemu on macos x 10.5.8 there run on 64 bit.

Certainly not 3 times faster.

Soon i will reinstall lubuntu on my quad and will make new bench and shots for now this are the performance of the buggy VirtualPc 7.02 on G5 (it use only on of the quadri core) it is not optimized for g5 but can made understand the performance of this cpu

That was my point - 970MP is powerful, much more than PA6T. 1194 DMIPS - Pentium III 750 MHz class performance.

@pavlor

Think this on the Lubuntu i have 1.97 points on integer and on MacOsX 10.4.8 = 1.54
is about 30% more il PPC64 kernel on lubuntu.
the host os make many difference on the Quad G5 because all software are not optimized for this machine on the MacOSx side ...
apple drop down the support too soon the Xcode was updated on 3.1.2 just couple of months before the 4 exit without PPC support

Another test i made was yabuze on the
Quad G5 Nv 6600 MacOs X = 35-42 fps
Quad G5 Nv 6600 Debian Wheezy = 60-120 fps

about virtual Pc
1194 DMIPS - Pentium III 750 MHz class performance
not bad for an old and not optimized emulator :)

Yes 30 %, but not 300 %.

Without doubt. That should be enough for most non-3D demanding games - if the emulator is stable and compatible enough.

@pavlor

Yes , the best emulator for Mac was the Guest PC it was gaving good performance on 3d emulated game because it was using the Voodoo video board direct like was native .
But was discontinued and the Virtual Pc never was updated for use 3d or gl :(
Same as the Qemu no 3d just the vmware video svga but the overall performance of this emulator in not kvm is crappy compared Vpc or the old guestpc for play 3d games just for fun.

Exactly. Pentium II 350 MHz class performance on Core i5 is rather low result (I use old QEMU 0.8.2, newer versions are a little bit faster, but behave strange on my system). Still enough for old Windows95 games not compatible with Windows 7 (like Dungeon Keeper).
For 3D demanding old games that don´t work on Windows 7 I use VirtualBox with Windows XP (good eg. for Master of Orion 3, but not useable for Morrowind - 3D speed is OK, loading times of locations are too long).

@pavlor

i m lucky i finally found guest pc ... on a cn server.... 1.3kb/s download time 54 minutes :P I have a new toy for play :D :D (hope)

this are the real Qemu 2.0 Performances









Quake 320x200 = 7.5 fps ...

ORRIBLE!

@tlosm

Use DHRY2OD to get better values (ND has no optimalizations). I expect you could get around 150-200 DMIPS. 46 DMIPS in DHRY2ND is similar to Pentium 166 MHz.

CPU seems to be fast enough, maybe GFX slows it down.

@pavlor

Mips 113.55 (Qemu-system-i386 2.0) Vs 1175 of VirtualPC is 1/10 of performances


Ps: i found on trick with virtual pc under windows 95
Quake time demo demo2 320x200 = 98.4 fps
Quake time demo demo 2 640x480= 54.4 fps

The cpu information is different compared the other on other systems i found pentium II class here is Virtualcpu
I think it was the original Insinia cpu make for the old Virtual Pc and was really performance boost

The AmigaOne Xe g4 933 with Quake at 640x480 in software rendering gave me 47 fps and


Really Not Bed!

edit : i had been installed Homeworld e Unreal e Alien Vs Predator and are full playable in software rendering dx too...now i will try something more heavy :P

@tlosm

and DOSbox or other systems how it works?

113 DMIPS in DHRY2OD? Still low (Pentium 100 performance).

Good Luck! It can be hard to find decent game supporting software rendering.

@pavlor

there are other games that run in software mode: Descent Freespace, Wing Commander Prophecy

@pavlor

i say before the performance of qemu are worst compared the other pc software commercial in the Mac ppc scene.
Form:
RealPC , GuestPc, Softwindows and VirtualPc i can say the best are Real and Virtual. I will make only another test will try the old macos 9 pc emulator under shapeshaver and check there overall performances

Yes i know it is hard , i Will try to find some wrapper like glide wrapper and test there, in any way is just for fun for play i have my consoles included ps4 ;)

Wow, those framerates are horrid. Using my 6-7 year old amithlon box I get roughly 120fps in quake using software rendering @640x480. Even pc-task, running on an emulated 68k cpu gives better framerates than those quoted from qemu running native on a g5.

Slightly off topic, but relevant to the thread Ive recently managed to get qemu to run inside Dosbox on AROS. Given its virtualisation its actually pretty nippy (Dosbox on x86 AROS is probably 10x as fast as equivalent ppc system).

A quick list of some of the emulators Ive ported to amigaoid systems:

Dosbox.
Bochs.
Atari800.
SGCube (gamecube emu)
Handy.
InfoNES.
PC-Emu.
Hatari.
Dgen.
Sim80.
Neopop.

Dynamic CPU core in DosBox is cca 4x faster than normal CPU core. Gives similar result as non-accellerated/virtualised QEMU on Core i5 of my brother.

For DOS or something more interesting?
What speed you get? I estimate 486DX performance at best.

Quote:

There is no doubt that VirtualBox on Windows is 10 times faster than Dosbox on x86 AROS on the same pc.

@pavlor

Its significantly more than that. You cant use cpu cycles as any sort of indicator. It simply doesnt work that way (Ive seen you use this as a point of reference many times)
As for qemu virtualization under dosbox, even on my piece o' crap athlon64 x2 aros laptop virtualised qemu speed is something akin to a p200 (dosbox adds another 50% or so).
And no, its not restricted to dos or win9x by the way. MMU and FPU emulation are the biggest obstacles once you add win32 pe loader.
Seriously though that i5 of your brother sounds awful. Your benchmark figures are always orders of magnitude slower than what I experience on my core2 systems let alone my own i5, and thats a laptop. The i7 blitzes that mac?hine as well.

@mailman2

Of course virtualisation when utilizing more than one core is going to be much faster than emulation on one core. Was there a point other than stating the obvious?

I´m always rather conservative in my estimates.

Quote:

Virtualised means it uses virtualisation features of QEMU (similar to native speed, DosBox speed in this case), or it uses plain dynamic recompilation of QEMU (that would be 486DX I wrote above)?

@pavlor

Its also possible to Virtualize without PAE or NX. Doing so (ergo losing accelerated virtualization)gives the user performance somewhere between a dynamic emulation and .what people nowadays call Virtualisation. Qemu offers this, ergo pretty reasonable performance.

Slightly off topic, but damn, OS4 hardware just seems more extortionate all the time. Seems its performance is struggling to keep up with these sorts of systems (none of which are high end) when said systems are also dealing with multiple layers of emulation, and theyre more expensive to boot.People talk of an Apple tax at times, but even Apples overpriced systems are value in comparison. None of this a revelation, but this thread really does highlight it.
