I'm curious to see some benchmarks from MorphOS.
Especially 68k emulation, and the difference between Amiga Classics with CSPPC/BPPC and Pegasos 1/2.

(Benchmarks from Dnetc 68k for example)

@tomazkid

Last benchmark battle what we've made was on fYa#12, on the big screen... It was Cinema4D rendering, of some default pic (earth with stars or stg).

Petunia on uA1/750GX@800 completted the task in 16 secs.
Trance on Pegasos 2/G4@1Ghz (MOS 1.4.5, not internal beta) completted the task in 8 secs.

Rachy later explained the results as "Cinema4D uses mathlibs, which are not yet native on OS4". I've some doubt though if Cinema4D, esp. the FPU version uses mathlibs while rendering. But i haven't investigated it further.

I'll do some benchmarks after my uA1 got Upd4, you can be sure about that.

Would have been interesting to have that checked using SnoopDOS or something alike.

I am also eagerly waiting to see how Petunia from Update 4 performs. Then we can do some "real" benchmarking, since there won't be much changes to the final version, I guess.

@tomazkid:

Once Petunia is released, I intend to do a couple of comparisons using HD-Rec.

The main reason is that, currently, my 600mHz, 128meg Peg1/MOS1.4.5 absolutely zooms compared to my 800mHz, 256meg A1/upd3.

For instance, I can have several effects running on the Peg at one time but anymore than two n the A1 and I get "not enough CPU".

I expect the A1 to outdo it once Petunia is released but we shall see...

Basically it's useless to do these tests unless you're running them on the same
hardware.

Wait for OS4 final and do some tests on a classic setup. That's a more fair test.
Because testing a Pegasos vs a µA1-C (with its lightning fast™ north bridge)
wouldn't really be fair at all.

If I remember correctly the Pegasos II had more than twice the memory speed
of a µA1-C, someone posted ages ago.

That would mean nothing. One app could still open the mathlibs to use some helper stuff (for example to get some float values more precisely) then render 100% using the FPU only. Some '060 demos known to do that for example. They generate tables and some pre-calculated stuff using mathlibs on init, then don't touch the libs any more.

@Robert

It should really. Petunia is 4-10 times faster than the current emulation.
It will truly be nice to play with when released

Well, i agree. However, there was much hype - here in Hungary at least - about 750GX's FPU being faster than G4's, and about Petunia's speed "because it's in assembly", while the only benchmark i know shows quite the opposite.

Quote:

If my memory serves me well, the Pegasos II with G4/1Ghz has uncached memory write speed of ~420-440MB/sec, while has read speed of ~210-220MB/sec, according to MorphOS's own memtest utility. That's more like the advantage of G4 though, because with G3, the memory speeds are much slower, also on a Pegasos II. What utility is there to test the memory speed of an uA1 on OS4?

Anyway, a twice-as-slow-as-trance Petunia would be still a HUGE speedup compared to the current interpretive emulation. Still, you can't blame anything on the hardware, because DVPlayer runs quite fast on uA1, and sometimes outperforms an MPlayer running on a Peg2/G4.

INT READ: 3340 MB/sec
INT WRITE: 1610 MB/sec
FP READ: 3700 MB/sec
FP WRITE: 1612 MB/sec

Some question remains as far as reproducability with ramspeed (source available), and what was happening in the uA1-C's numbers for writes. The numbers above were taken by basically throwing out the 'in-cache' hits, which are pretty boviousl when you run the test, to use as a mostly apples to apples comparison.

The Peg2 and A1s overall (well, unsure about INT writes on the uA1-C given) are 'pretty comparable,' while similar Apple hardware does better across the boards, perhaps not too surprisingly. I added in the 1GHz PowerMac, PIII server and P4 numbers ofr relative comparison, from compiled binaries using the same version of gcc where possible, as native compilations on each system.

Did you run any tests with registered versus unregistered RAM in the A1's ?

Good question. I've got a _huge_ data file with data from all my test, just to handle questions like that (and evidently because of the fact that I suck and forget things ). I'll check, but may not have written down which module was in it (If I had given a ram size in the tests, I'd know, it's either a 512MB Registered ECC stick or the 256MB stick supplied by EyeTech, which I'm unsure right now if it's reg or not).

The RAM I _currently_ run is Registered, I'll try to kick off a few runs later tonight after work and see if there are any changes.

Oh, at least with respect to the original tests, the tests done under Linux were the same hardware, with little to no difference, so at least we're showing the test is valid for relative (hardware) comparisons, although cache sizes vary so still need to 'adjust' to a standard measurement of sorts. DrBombCrater and others more knowledgable than I piped into the original thread and clarified some aspects, so it's worth a read of the original linked thread even with the many re-posts of tests etc.

I asked due to the "fact" that unregistered is usually considered to be faster afaik.
I've got an unregistered 512Mb dimm in my A1, might run some tests later.

@thread

Isn't there any Peg-owner that is willing to give some Dnetc 68k benchmarks from MorphOS ?

Yes, it is generally a 'fact' that's been confirmed many times, but yeah, definitely run a few but refer to the original thread as to how we were arriving at the final numbers.

As far as I'm concerned, it's not a huge deal here, but is interesting. We know the A1s aren't speed demons with respect to most things (of course, AltiVec rocks where it can be used though!), and while benchmarks can be interesting, they can easily be taken as showing 'the wrong thing,' if a test isn't doing exactly what you think, or you're using the wrong criteria for testing, etc etc..

(Yeah, I'd still like to see your test though! )

Wopsie daisy.. Is that twice the MOS speed I'm reading or am I misreading
the numbers?

This really shows how slow the 68k emulation is when interpreted. JIT will
make it atleast 10 times faster I think.

If my memory serves me well, the Pegasos II with G4/1Ghz has uncached memory write speed of ~420-440MB/sec, while has read speed of ~210-220MB/sec, according to MorphOS's own memtest utility. That's more like the advantage of G4 though, because with G3, the memory speeds are much slower, also on a Pegasos II. What utility is there to test the memory speed of an uA1 on OS4?


Well That depends on the G3 CPU. The GX is quite much faster than most of the
G4's we're talking about (up to 7447). But the bad memory controller and slow bus
(133MHz vs GX own 200MHz) slow everythig down on the µA1-C.
Excluding altivec code of course.


EDIT: about DVPlayer vs MPlayer.. Yes but DVPlayer is heavily optimized for AmigaOS
and that's not the case for MPlayer which on OS4 is quite slow in comparison.

You are misreading the numbers. 22Mkeys/sec is OGR speed, not RC5-72. I can give you exact dnetc benchmark results from Peg2/G4 running beta MOS kernel (with AltiVec support) tomorrow if you wish.

The GX is quite much faster than most of the G4's we're talking about (up to 7447).

No it's not. My GX/800 gives 2.7Mkeys/sec in dnetc. That's multiplied by 1.25 (to have a result from a theoretical 1Ghz version) gives 3,3Mkeys/sec, which is good, but still a bit slower than my G4/1Ghz is able to archieve, without AltiVec. (And don't forget, the GX has double the cache.) And it doesn't count IMO that the GX could go with faster buses, since the 7447 also has a 166Mhz bus mode, which is unused on the current machines.

I think it all depends on optimization. You can write code, and there is code which runs faster on the GX, but for generic cases, i still think the 7447 is somewhat better, and has more spare performance in it, thanks to AltiVec.
