TCPMP performance on Trinity and Wizard

[meroupow]

I recently bought an HTC Trinity also known as P3600.

I installed TCPMP and launch video. Of course I got the problem with Imageon and switched to raw framebuffer.

Image quality was OK (although compression artefacts are more visible on trinity than Wizard) but performance seemed low.

So I ran benchmarks and surprisingly the trinity (cpu= 400Mhz) is much slower than my wizard (cpu= 225 Mhz).

I get 118% for trinity and 152% for wizard for the same movie and the same parameters for TCPMP 0.71.

What can be the explaination???

My HP 4350 with cpu 400 Mhz is well above 250% for this movie...

This makes no sense for me. It's like my wizard is running 200 Mhz. Or maybe Samsung processor is crap but I read somewhere it is good.

below are test results (I stopped them after 30 seconds because it is not necessary to bench the whole movie to see there is a problem)

Interesting. I have seen benchmarks for the Omap processor that showed very good graphics performance, even better than much faster processors because of a separate accelerator inside the chip, maybe that is the reason, or maybe TCPMP is just not optimized to use the new Samsung processor to its maximum potential.
