ragemem benchmark results thread !

I?m a litte bit curious how fast the ram- and videoram-access will be on the sam460ex with its pci-express and ddr2-ram?

I?m asking, because i want to buy the 460ex beside my sam440ep.

@Raziel

I tried 0.35 (both A and B) and the results were pretty much the same between them (A + B) and between 0.34. It didn't crash when it reached the vmem bench, but didn't return any results either. That's on a Peg2 as I said.

edit: I tried with 0.34 again without startup and it worked. So, here's the videomem results:

---> VIDEO BUS <---
READ: 56 MB/Sec
WRITE: 184 MB/Sec

no results with new version even without startup

Here's my results:

What's the difference between A and B programs ?

wow, this looks not bad!

Why is write nearly always faster than read?

Why do the SAM video bus benchmark look the pci bus is running at 33MHz?
I expect write speeds closer to the A1 or Peg2.

A1-XE with 7457 CPU running at 1066 MHz.

I do have an L3 cache on the CPU module, but I don't know how to enable it. I remember Alan Redhouse saying that it made hardly any difference. One of these days I must try it out.

So, we have interesting results. Anyone with AOne X1000, Friedens?

Hi people!

Uploaded v0.36 on Os4depot.

Do not use v0.35 anymore, this was just a test to try some fixs: Results are WRONG.

This v0.36 got a very crappy video test, but at least it should works on all Amiga. Sorry about that, I don't actually have a lot of time. Have to wait a few days

Ah! My 3.3 Apollo is a 7455A@1.4 Ghz, that's explain the version number (UBOOT returns it to be 400 Mhz, but it runs 1400).

@Crisot

Found a few differences in my system's results with this new version, for example L1 write cache seems much lower than before...

@Daniel

Yes this happens on 440, but I still don't understand what's the problem. Maybe it's related to something in my code going wrong with 440.

Unfortunately I don't have a Sam to test... I'll have a look at memory alignment.

My goal with this update was to have a working video test, for the Sam460. L1 speed fix in next version, I hope

@m3x

Not bad compared to the results from a Peg2 (below) which is considered the fastest OS4 machine.

*** L1 CPU cache (32KB buffer) ***
READ: 6534.77 MB/sec
WRITE: 2157.15 MB/sec

*** L2 CPU cache, if present (256KB buffer) ***
READ: 1989.89 MB/sec
WRITE: 1739.42 MB/sec

*** MEMORY (16MB buffer) ***
READ: 135.15 MB/sec
WRITE: 796.26 MB/sec

@Elwood

Hey, the fastest Os4 machine is MY Aone

Kidding.

Hum, many thanks m3x, but I see there is still a problem in the L2 write speed...

I have an idea... have to do some tests here.

EDIT:

New version:
http://crisot.free.fr/universe/files/RageMem.lha

-Now bench in 32 bits and 64 bits modes.
-Slow L1 issue should be solved.
-Added a mini "MAX MIPS" bench, just for fun (see readme about this).

i know you wrote the program but i hope you have not finded tuned it for your system (joking).
