Title: SL-C3000 questions
Post by: Newbix on November 13, 2004, 04:17:38 pm

Hi,

I've got some questions about the SL-C3000 but I didn't find any detailed review:

- What is the graphic chip of the C3000 ? Intel 2700G ? ATI Imageon 100 ?
- Does it allow full screen video playback ? How many video RAM is there ? (see this post (https://www.oesf.org/forums/index.php?showtopic=7751&hl=xrandr&st=15#entry48258))

- Is there any benchmark of the Microdrive ? How does it compare to solid state CF/SD or internal flash?

- How does the new CPU (PXA270) compare to the old one (PXA255) ?

Thanks for any answer...

Intel's PXA270 site: link (http://www.intel.com/design/embeddedpca/applicationsprocessors/302302.htm?iid=search&)
Improvements over the previous generation of X-Scale processors include Wireless MMX (multimedia acceleration) and SpeedStep (adjusts CPU speed dynamically to extend battery life)

You will have to wait until I receive my C3000 on Monday to get answers to your other questions.

To the speed of the built-in Microdrive:

I've just compared the speed of the built-in Microdrive to an external CF-card (Sandisk Ultra II 512 MB).

Write-test:

Code: [Select]

TESTDD=/mnt/cf/test-dd
date; dd if=/dev/zero/ of=$TESTDD bs=1M count=256; date
TESTDD=/hdd3/test-dd
date; dd if=/dev/zero/ of=$TESTDD bs=1M count=256; date
Read-test:

Code: [Select]

TESTDD=/mnt/cf/test-dd
date; cp $TESTDD /dev/null; date
TESTDD=/hdd3/test-dd
date; cp $TESTDD /dev/null; date
The results (read - write):
Microdrive (2.080 kB/s - 1.986 kB/s)
CF Sandisk Ultra II (2.221 kB/s - 2.730 kB/s)

Of course, this test doesn't meassure the random-access-speed!

Nice infos about CF-card speed can be found at http://www.robgalbraith.com/bins/multi_pag...p?cid=6007-6133 (http://www.robgalbraith.com/bins/multi_page.asp?cid=6007-6133).

It would be very interesting how fast the internal RAM-disk of the other models is, e. g. C860, C1000!

Did anyone change the C3000-Microdrive into a CF-card? Does that show speed improvements?
