That's good news. Eager to see benchmark results. Kind of like Acube (disagree on their particular design choices and price policy though),hope Acube recover their investment quickly and make a smarter cpu choice and simpler board next time.

Still no high speed usb is - well - not surprising. Isn't it beta since ages? Seems to need massive testing...

Let's see some real-world benchmarks before denouncing the SAM460...  The G5 Macs only got up to DDR2-533, iirc.  If this board can support DDR2-800 and higher, then real-world benchmarks will get interesting...

Well, high clocks are not sufficient when either the design or the cpu is weak. Except for the video bus the Sam 460 gets outperformed by a 167 MHz FSB Mac mini in regard of mem access: http://www.morphzone.org/modules/newbb_plus/viewtopic.php?forum=3&topic_id=7001&sortname=&sortorder=&sortdays=&viewmode=flat&order=1&start=40

I repeat the values for RAM access here:

Sam 460:
READ32: 311 MB/Sec
READ64: 310 MB/Sec
WRITE32: 521 MB/Sec
WRITE64: 521 MB/Sec
WRITE: 1251 MB/Sec (Tricky)
 
Mac mini G4/1500
READ32: 387 MB/Sec
READ64: 403 MB/Sec
WRITE32: 771 MB/Sec
WRITE64: 771 MB/Sec
WRITE: 809 MB/Sec (Tricky)

Plus, the presence of a FPGA open up more opportunities to personalize the board for the industrial market, since there is still free space to be used on the XP and XP2.


While you are just here: can you provide a rough nimber about industrial use? No details needed, but are industrial customers rather 10% of the market (in the manner of sold items) or 90%, 0% or 50%. Your word would be evidence enough for me.
