Anyone want to do a mplayer  benchmark using the following video ?

post_id=91172#forumpost91172[/url]


Powerbook 5.6 (1.667 GHz)

BENCHMARKs: VC:   7.819s VO:   3.808s A:   0.000s Sys:   0.255s =   11.882s
BENCHMARK%: VC: 65.8037% VO: 32.0497% A:  0.0000% Sys:  2.1466% = 100.0000%
VO: Enabling blanker

Pretty close to X1000.

While I prefer MorphOS over OS4 I must say the Sam 460 is an interesting machine though. Albeit a bit expensive. But it's new (which in some occasions is a plus) and speed is okay for many things.

Generally I don't have concerns to buy used computers, I never had a failure and my mini is up and running since 5 years (-3 days to be precise, MorphOS 2.4 got released on 12 October 2009) now. If it fails tomorrow I just head over to ebay and get a replacement machine which costs pocket money only (quick check on ebay.de reports G4 1.5 GHz mini 1 GB RAM 64 MB VRAM, refurbished with 1 year warranty starting at 109 EUR). It's a easy shot. If you don't like it dump it off to ebay again and get the similar amount back.

Not really, because your comparing bananas with apples.

Your comparing ARGB bitmap graphics with YUV420 overlay, two different technology’s.

YUV420p is a 12bit format vs ARGB a 32bit format.

http://en.wikipedia.org/wiki/YUV

ARGB = 640x480*4 = 1 228 800 bytes
YUV420p = 640x480*6/4 = 460 800 bytes

ARGB takes 266% more space then YUV420p, conversion & bandwidth is also costly when you most use ARGB.

So basically the AmigaONE-X1000 has to work harder to display the same graphics.


Sorry, but that's just a (lame) attempt of a academic excuse.
I compare exactly one thing:

How fost does my powerbook replay a certain video and how fast does it an X1000 or Sam460.

Today, reproducible and reliable. Why the result is like it is is not of my interest. I wanna watch that video, not think about the technical internals. And I give a certain brown matter about what could be in future. It matters what's actually there. And for that i provided numbers. They speak for themselves.

But hey, yeah - two more weeks and everything's brilliant of course.
