Bustest scores for various systems

Here are a load of bustest scores for fast ram from a few different system configurations. Some are medium word and some are long word, so not all scores are exactly comparable but should be pretty close.

Code:
1) WarpEngine 060 96Mhz (ram 48Mhz) = 54.3MB/s readm, 34.3MB/s writem
2) WarpEngine 80Mhz (ram 40Mhz) = 45.4MB/s readm, 28.0MB/s writem
3) WarpEngine 50Mhz (ram 25Mhz) = 27.7MB/s read, 17.8MB/s write
4) WarpEngine 040 40Mhz = 51.8MB/s readm, 28.5 writem

Please post your own results and I'll add them to the table, or to update my figures if they're wrong

https://aminet.net/package/util/moni/bustest

Basic usage is (in a shell): bustest fast
You can also get chip and rom speeds with "bustest chip rom". All three can be strung together.
For specific address ranges (ie you want to test zorro 3 ram rather than your highest priority ram) then consult the documentation, but it's basically bustest addr=07010000

The error problem with Bustest is the data cache is enabled (by Setpatch). Now, most results for the Fast RAM and Kickstart ROM are a mixture (cache + memory). But Chip RAM is correct (Thanks to the cache disable in hardware).

The short solution is - "CPU NODATACACHE" but is anyone interested? Probably not...

P.S. I already posted this reply on A1K.org (using my crappy German).

I don't see that as a problem. You get (much) slower values if data cache is disabled. Practically CPU caches are activated and used in "real world" situation. To compare different systems it is good enough IMO and the important bottleneck is chipram what gives correct values. However, why not write a bus speed test program that measures real bus speed?

From the Bustest documentation:

"Bustest is a small utility to measure data transfer speed
to and from memory."

The speed of the data cache in many cases is very much faster than physical memory but there is a notable exception for the 040 and 060 with the "Copyback" mode (see the Bustest documentation).

Now, how can you expect realistic results with 3 different CPUs having different data cache sizes and modes, unless those caches are disabled by default?

Just measure chipram for "realistic" results. Or use SysInfo.

Great link, many thanks! I had no idea that was on eab. I’ll take a few results from there to add to the op

Looks like I need to get some faster RAM for the CSPPC, but they are a bit arsey about the internal chip layout. And the Apollo is crappy...

Also a list for accessing RTG RAM
Also Wrangler after you release that EMU10k DSP driver on monday, can you build bustest for WarpOS?
