vampire video speed vs dedicated RTG cards

[Nickman]

I have an A500+ with an vampire.
Can run all the tests you want to see.

Link to programs and what to test and i'll post the results here.

Mein Deutsch ist nicht mehr gut
Luckily Google translate works very well, and yes this article is useful.

If you are willing it would be interesting to see how higher and higher video resolution *depth * rate effect cpu and memory performance.

I guess the easilest would be to use at least 4 resolutions @ the same 24 bit at a fast frame rate.  A control would be the same parameters only using a RTG card.

Sure can test that tonight when i get home from work.
What CPU test bench do you prefer?

I am looking forward to your review/comparison.

I always find enthusiasm overruns Apollo core users like a religious sect. So they tend to publish benchmarks that specifically favour their agenda or corner cases where they can show off.

I believe you are one of the first ones I see that dont belong to that group. I will love to see the pros a cons of the SAGA rtg implementation.

Well this is not my feeling, about sysinfo scores and such yes i agree, that said about videos from some users, i think they just shares what they experiments, with some enthousiasm yes (too much ? maybe, but certainly not sectarism) but hey this board is enthousiastic when you have one.

Since the RTG drivers are not optimized for AMMX, it may be a bit premature to do speed benchmarks but the display DMA should be nearly finished in Gold 3.

Picture grabbed from SysSpeed v2.6 running at different resolutions on my WB.
Missed part of the benchmark when grabbing 640x480.

[darksun9210]

awesome work. hope to get my benches up here shortly

[Gulliver]

@Nickman
Thanks for the post.

It is interesting that drive performance decreases whilst resolution increases. So drive and also cpu performance is reduced when resolutions increase.

It would be good to know what other subsystems are affected (ram, io, etc.) and up to which extent (percentage of reduction).

[Motormouth]

@Nickman

I agree with Gulliver and Darksun9210
This is quite useful!!!!!!  I wonder how other video card will compare with increasing resolution.  They will also have some penalty, but I image it won't be as much.

But let us put this in perspective even a "slow" vampire is still amazingly fast.....

[Motormouth]

Since the RTG drivers are not optimized for AMMX, it may be a bit premature to do speed benchmarks but the display DMA should be nearly finished in Gold 3.

@SamuraiCrow DMA will help.  I have been impressed with the speed increases with etch new core Apollo has released.

There must be a copy/paste error on DrawEllipse 1280.

All are 24bits scores ?

Of Course you are right. DOH!
All the results is on the previous page.. Had some time off at work today over lunch so i played with Excel

Typed all figures manually so missed a 0.

Updated the post with new image.

When i saw those results posted earlier i got curious how memory speed would be without saga running at all...

Some explanations on results you see here.

v500+ pal2: saga monitor driver is not in devs/monitors, and running pal640x256x4 when testing.
v500+ pal1: saga monitor driver is loaded from devs/monitors, but the resolution is switched to pal640x256x4 before running the test.
you: this is test is run with the screen resolution you see in the screenmode prefs window on the screen. This is the same saga resoultion used in v500+pal1 test, so switching to no-saga resolutions seems to have the saga-core running in the background when not used.

running v500+ gold core 2, and i believe x11 speed.

cheers!

To get full speed when using the chipset, you need to use a special command to deactivate the HDMI output.  The trouble is, I don't remember the custom command.  It is one that was created by the team.
