vampire video speed vs dedicated RTG cards

[SamuraiCrow]

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.

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.

That's the one!  Thanks ShK!

I read that the new board design was to allow higher clock. We'll see if it works.

The newer board design is likely to use a newer FPGA.  For example, a Cyclone 5 supports DDR3 memory while current designs use a Cyclone 3 with SDRAM.

Which Vampire board design are you referring to? Vampire 500 V2 to Vampire 500 V2+? Other?

Stand alone Vampire to V500+/V600.
