QEMU Emulation vs Hardware CPU Benchmarks
Home away from home
Home away from home


See User information
I'm interested to see the raw CPU performance of QEMU on various machines vs real AmigaOS 4.x hardware. So, I've put together a smal script with a set of CPU benchmarks.

EDIT: You can download the benchmarks here.

Please post the results here (deleting the unneeded extra output in the Dhrystone & Quicksort tests), together with you're system's specs.

Hans

Great thread! My A1222 showed virtually identical results, except for the Whetstone results:

One other point is that the RageMem numbers may be off; the video bandwidth numbers, for example, are absurdly low. I suspect RageMem may be hitting the FPU emulation layer. In which case the numbers both are and are not correct. They would be correct in so far as it shows the impact of floating-point emulation. They would be incorrect in terms of reflecting actual HW bandwidth.

I'll go ahead and and try and verify/disprove that hypothesis shortly.

No, CPU access to VRAM is extremely slow on all systems. Both the read and write results of the A1222 are about 1/3 of the X5000/40 ones.

As a quick test I added RageMem to the LTE blacklist, and wow, was it slow in finishing. That alone tells me that FPU emulation is impacting the numbers; and with LTE disable the results were substantially worse as expected:

So I wonder if we can get Crisot to build us a version using unsigned integers rather than floats, if possible, for an A1222 test. That should be possible since for some CPUs he already does that. This doesn't matter for the other benchmarks, since they are supposed to measure workload performance, and if FPU emulation kills the result, so be it. But for something that should be an indicator of relative HW bandwidth, we should take the emulation issue out of the equation if possible for a more accurate comparison. IMO, of course.

So I wonder if we can get Crisot to build us a version using unsigned integers rather than floats, if possible, for an A1222 test.
Not possible since 32 bit CPUs don't support 64 bit integer loads/stores, 64 bit accesses are only supported for double (and 128 bit accesses for vector on some CPUs).
64 bit C integer loads/stores have to be executed as two independent 32 bit assembler loads/stores, and you have the results for 32 bit integer accesses in the READ32/WRITE32 results already.

Now can I please get a 32 bit driver for AmigaOs4.1 so we can move on to the GPU benchmark ? Don't take it seriously it's just a joke...

Thanks again for the script and merging the CPU benchmarks.

I am somewhat pleasantly surprised that these results are so different.....es shows once again how strong this ARM Cpu is, but also shows its weaknesses in some areas.

That impressed me the most, how does that come about, maybe it's because the main memory as well as the garficard memory are used as shared memory.

With the benchmark you can imagine how well AmigaOs4.1 with Qemu runs on my machine. That is the point why I chose this emulation, it gives me a good feeling to be able to use AmigaOs4.1 under it. AmigaOs4.1 runs albeit somewhat limited as my 2nd operating system thanks to Qemu.

Numbers can be manipulated, with videos it becomes very difficult, if they would like I can also create a video about it again.

Yes, the FPU emulation gets in the way of some of the copy benchmarks. There's clearly something wrong on my system with the Whetstone benchmark. Maybe I haven't kept my system up-to-date enough...

Quote:
Not possible since 32 bit CPUs don't support 64 bit integer loads/stores, 64 bit accesses are only supported for double (and 128 bit accesses for vector on some CPUs).
64 bit C integer loads/stores have to be executed as two independent 32 bit assembler loads/stores, and you have the results for 32 bit integer accesses in the READ32/WRITE32 results already.

You're clearly unfamiliar with the unusual P1022 CPU in the A1222. It doesn't have a proper PowerPC FPU, but does have 64-bit GPRs which can be used via its Stream-Processing-Engine (SPE). The RadeonHD & RX drivers both have SPE optimized copy routines in them.

Yes, the results are interesting. I am impressed with the ARM numbers. Derfs' Ryzen numbers are also significantly better than my laptop.

@all
Has anyone tried Qemu on a Raspberry Pi 4 or a PineBook Pro? I'd be interested to see what a weaker ARM CPU can do (one that doesn't have Apple's M1 extensions to aid with x86 emulation).

Because you are testing mainboard RAM accesses, the part of it used for the SM501 emulation, not gfx card RAM accesses.
The RageMem L1/L2 cache results compared to RAM ones are of course wrong as well, your host CPU has much larger L1 and L2 caches than the emulated 32/512 KB.

Unlike QEmu UAE seems to support direct access to the gfx card, for example compare derfs QEmu results (11034/5330 MB/s) with the UAE (51/49 MB/s) ones.

To get usable gfx speed you need an AmigaOS gfx driver for QEmu, just like the uaegfx driver used in UAE.
Best way for implementing a QEmu gfx driver would probably be one using Cairo and/or OpenGL, that way it would work with any host gfx card.
The currently used SM501/2 emulation is the worst possible way, because of it's strange 4 byte 24 bit modes neither supported by AmigaOS nor host gfx cards, and even emulating a Permedia 2 or a Voodoo 3/5 would be much better than that.

I tried the Qemu 8 under Raspberry Pi 400 some time ago and the feeling I had was that it was slower than my classic PPC A1200. But I will try to run it again and get results based on your script.
