@bernd_afa

see my last post it`s being updated new test result for Blizzard PPC 334Mhz.
there has been some newer improvement on my card but can`t upload test just yet.

if possible remove all old test result for Blizzard PPC and replace with new Blizzard PPC @334Mhz.

also new 68060@76Mhz on Blizzard no data trashing (fixed)
new Bvision 100Mhz memory clock new standard.
new PCI bus speed 38Mhz but can operate @43Mhz under OS4.0 only (awaiting possible fix for OS3.x).

>That says something about this test...

I develop the compiler optimizer(for amiblitz) and learn a lot about CPU architecture to do this.

and during that i find out, the real world fft and inverse fft for float and integer is a good test situation to see how good a CPU perform in out of order execution and performance /MHZ.

But of course more tests are better, because CPu architecture can be so diffrent that a CPU can in 1 program faster and in other slower.but thats only around 10-20 %.

maybe HammerD can do the mp3 encode benchmark with his cyberppc OS4.so we can see if the result differ much from this bench.

http://amigaworld.net/modules/newbb/viewtopic.php?topic_id=30008&forum=2#576603

The IBM G3 freescale 604e G4 G5 PPC(the extreme expensive Power CPU i do not count) is the glory of PPC, all other later PPC designs are target to embedded and trim to use less power and so they give less performance per MHZ.

but i find intresting, that the old Cyberstorm PPC in a design of 12 years ago with slow EDO RAM give such a good performance in compare to SAM

Yes, that would be better benchmark.

You mean that other designs than 604e, G3 and G5 give less performance per MHz? Or that even G3, e600 and G5 give less performance per MHz than 604e?

How memory intensive is your benchmark?

>You mean that other designs than 604e, G3 and G5 give less performance per MHz?

yes, but G3 from freescale is too slow.only G3 from IBM is fast, have faster FPU as G4 from freescale, only miss altivec.g3 freescale can cvompare with the 603e.

but as far i known no Amiga PPC system use G3 from freescale.

>How memory intensive is your benchmark?

dont know exact, but i guess 20-25% is uncached memaccess done.

but you can see the memory slowdown effect when you compare the speed at 500 MHZ of the SAM 667 and 800 MHZ.the 800 MHZ version is not depend on clock speed faster.

same you can see on the cybppc 150 to 366 speed when look at 500 MHZ time

Remember that 750CX/CXe/FX/GX are newer than original G3 CPUs from both IBM and (then) Motorola, thus their speed advantage is logical.

Nonsense. At least integer performance per MHz is on par with 604e (much better than 603e). Even 440 core has (much) better performance per MHz than 603e (compare SAM and Efika).

and where are values that can compare between efika and SAM ?
I still think 440ep is the slowest PPC design ever build.

too bad that nobody with a efika do the benchmark here

Out of intrest, due to messing with ideas in data processing etc, can your code handle FFT of mega, giga, and possibly terra sample sizes, and if it can, does it at least equal theoretical slow down proportional to log log samples? As in, taking the FFT of a 1024 sample block takes x time, taking 1024 blocks therefore takes 1024 times, but taking the FFT of the complete 1024*1024 samples, takes twice as long, due to the log time taken to shuffle the 1024 blocks.

I think I manaaged to get some C++ source code example to work in HiSoft Basic in UAE on Ubuntu, so it would be intresting to see some more realistiic values for possible speed. 8) Currently I can only do a 256 due to plotting etc, so when I get it over a few seconds or megasample size, can see whats better and by how much.

thats not my code, but it can of course handle unlimet size.currently you can see on the test 413696 samples are process in this test.

see the output in the bench.

time needed xxxxxms for 413696 samples,

@bernd_afa

CPU was replaced with IBM 604e 350MHz and clocked at 366.667MHz with 66.667 oscillator and 5.5 multiplier.

66.667 x 5.5 = 366.667 MHz

My 060 is clocked at 50MHz still, but there is some timing issues, so I will replace 060 CPU with latest mask 060 and clock it using the same oscillator as the PPC clock so both CPUs will have same bus speed.

Hopefully that will fix the freeze I can get sometimes. RAM controller is very lame on CS PPC so you have to be very careful about RAM you select. My ram isn't so great. I have some IBM 72-pin simms from ebay on order, so hopefully they are better (they come from IBM server).

BTW my lame result (see private msg):

@HammerD

ok, thanks for info, your value show that on lame Test that SAM 800 is 64% faster as your 366 PPC.The SAM 800 user do not finish the lame test, normaly the Factor relatime decrease on longer test.so the SAM is maybe more slower.

and on this fft benchmark SAM 800 is 49% faster as your 366 MHZ cyberstorm with fft and float and 70% faster on integer.

I hope thats enough that pavlor see that this benchmark is near real world tests, but need less time
I dont know how much speed depend on FPU on lame or if it use more integer.

I hope you are joking... As you wrote:

That would bring some info to our discussion!

I think that even 666 MHz 440EP will be 60 % (or even more) faster than 366 MHz 604e (so 160 % of 366 MHz 604e) in integer operations. However, we can only interpret application benchmarks.

Did you mean user from this thread (Samo39, post 36) ?


@HammerD

Can you run OGR-NG on your 604e and post your scores?

This test is *completely* dominated by the 68K emulator.

I just ran it in E-UAE on my Mac. Going by the other scores a 2.4GHz Core2Duo should produce the second fastest result.

Actual results:
Float: 21862ms
Integer: 27557ms
integer: optimised 9691ms
According to the test it's the second slowest!

What's more according to the Mac's CPU monitor E-UAE doesn't load the CPU more than 24% even when set to max.

This shows 2 things:

1) This does not measure CPU speed.
2) E-UAE on the Mac sucks really, really badly (I don't think E-UAE includes the 68K JIT).

Yes this values from SAM 800

Encoding as 44.1 kHz j-stereo MPEG-1 Layer III (11x) 128 kbps qval=3
Frame | CPU time/estim | REAL time/estim | play/CPU | ETA
12948/12948 (100%)| 1:59/ 1:59| 2:00/ 2:00| 2.8233x| 0:00

But when i compare, the SAM user do use a other test.you can see diffrent frames.

thats from 366 MHZ cybppc

3.RAM Disk:> lame WhereDoAllTheJunkiesComeFrom.mp3.wav
LAME 3.98.2 32bits (http://www.mp3dev.org/)

have you a link how to do this and SAM values for this ?

you cant use some other benchmark values, because OS4 have only the GCC.so you should use OS4 values


>I hope you are joking... As you wrote:

this doesnt matter, FPu and integer differ only around 20%.

@minator
>2) E-UAE on the Mac sucks really, really badly (I don't think E-UAE includes the 68K JIT).

Yes your results show that no JIT is used.

only when a JIT is used, then it measure really CPu speed.

The test use asm instructions that every CPU have.

the JIT of the target system need only translate the instruction to a simular instruction of the target CPU.

thats a simple process and every JIT do in same way.

So this make sure, that no diffrent results due to diffrent compilers can happen and so can see how good the CPU out of order execution work.

see http://n1cgi.distributed.net/speed/

Remember that this sort of application is not much useful benchmark for comparison of different architectures. However, it gives some information when comparing CPUs from one architecture (eg. PPC). G4/G5 values are higher because of AltiVec.

ah you mean this benchmarks.this benchmarks do not have much memory access, and it use only very very few asm instructions. near all run in 1. Level Data cache.

this test show that the 440ep have good values,
but thats as you can remember the useless rc5 benches are the glory of PPC and every CPU developer of a PPC take care to make the few needed instructions for this, fast as other PPC, to show that his design is not slow.

that on X86 this benches are slow is because, X86 have no register exchange instruction.When this is add in X86 then it can lots faster.

but because high performance on such tests is only usefull for hackers, i think nobody add such a instruction in X86

We compared PowerPC to PowerPC, not PowerPC to x86 (etc.). In this regard is careful usage of OGR-NG valid, as I pointed in my prior post.

It is interesting that OGR-NG score scales with estimated CPU performance (eg. 68040 vs 68060 or 603e vs 750FX).

ah so the ogr-ng. i test only the ogr list.

but when you calc a little you can see that a SAM 440 ep or a 604e without second level cache or a G3 750FX with 512 kb 2. Level cache give near same performance.

so again here, this test run only in cache and its no real world situation, because in real world 2. level cache give speedup.
