The main difference might be video processing, OMAP4430 does 1080p 30fps and OMAP4460 does 1080p 60fps, though I don't know if the OMAP4430 at 1.2Ghz (the one also shown in the Toshiba AT200) if that one has more video processing. My guess is that all G9 could be OMAP4460 just down-clocked at 1Ghz and 1.2Ghz for Turbo for now.

Post here if you know something.

Some of my videos talking about the difference between OMAP4460 and OMAP4430:

A difference is for example than OMAP4430 can playback 720p in 3D, OMAP4460 can playback 1080p in 3D (if the HDMI supports 3D). OMAP4430 can do 720p HD video conferencing, while OMAP4460 can do 1080p HD video conferencing (although the built-in Webcam on G9 is 720p anyway, 1080p video conferencing would only work if a 1080p USB webcam in combination with 1080p HDMI output can be supported). The 1080p 60fps second support might also mean higher bitrates supported, which may also leave more capacity to fully support the 1080p h264 in High Profile and High Bitrate that one can download on BitTorrent, to be confirmed.

Early 2012, it might not be too early for Archos to even upgrade to 1.8Ghz OMAP4470 with even more video support, even more memory bandwidth and double the 3D graphics with SGX544 support. But that would obviously have to be confirmed. http://armdevices.net/2011/06/10/texas- ... n-october/ In theory the OMAP4470 is definitely as fast and most likely faster than any Kal-El devices rumored to be released at the same time, if the Kal-El devices are to be limited to the rumored 1.2Ghz quad-core.

Charbax have you received your Archos G9 yet it would be great if you could do a proper video review of the unit for us all. I still think there are alot of people uncertain still like myself

Archos hasn't sent me one yet, I don't know why. I'm hoping to get a Turbo soon so I can put it through benchmarks and heavy 1080p video tests, HDMI output desktop-class performance with keyboard/mouse, multi-tabs web browsing and many other things, with Flash 11 coming in October this should be amazing.

I expect all 720p movies to work perfectly no matter what, and probably also all 1080p movies even with highest profiles, highest bitrates, DTS audio, that all those will work.

For video, the hardware and codec support is more important than clock cycles. The 4430 should be just as good as the 4460, but in any case the G9s will NOT have the 1.5ghz chips unless there is an Archos refresh next year. If the video codec has to be pushed by the CPU, it will suck real bad for the battery.

Forget about the 4470 until mid 2012, since the 4460 is "sometime next year", per TI.

I found this article showing a SoM using the OMAP4460.
http://www.fudzilla.com/processors/item/24456-omap-4460-at-15ghz-makes-an-appearance

Anyhow, the good news is that according to the article the OMAP4460 could very well be seen in other devices in a few weeks. \:D/

The link they have to the manufacturer is broken, but here, IÔÇÖve fixed it. 8)
http://www.variscite.com/products/item/76-var-som-om44-ti-omap4460

And here is another link to the manufacturers YouTube account showing the system in action, playing Angry Birds at 1.5GHz and 1080p resolution. :-k
http://www.youtube.com/watch?v=cg9ky1a5SI4

Although somebody should get a kick in a suitable place for uploading it to YouTube at 480p and/or for using one sucky camera to film it. :evil:

They may say it's OMAP4460 1.5Ghz but that it isn't yet. Or maybe they have 1.5Ghz but only in low quantities which these types of development kits usually sell at.

The other good rumor is that Google and Samsung will unveil the Nexus Prime with OMAP4460 1.5Ghz on 19th October in Hong Kong at 10AM Hong Kong time. But, again there also maybe they say it's 1.5Ghz and maybe the samples are with that, but maybe they don't start shipping large quantities of OMAP4460 1.5Ghz in Nexus Prime until the second half of November or something.

Well the article mentions that they are shipping the module, so I would put my money on your second guess that itÔÇÖs a question of a low quantity product.
I was just happy to see a product actually running on the chip that IÔÇÖm waiting for.

IÔÇÖve also been keeping an eye open for the Nexus Prime, it is gona be one sweet device, cool design, great hardware and a possibly excellent OS.
If the rumoured 3rd of November sales release is correct Samsung would for sure want to stock up on phones before that so TI needs to have its production of 4460 up and running right about now (speculation and hope from my side).

I use my camcorder with 1080p50 frames.
I thought of connecting it via USB with a 101 (as external HDD) and review my results on the (likely) much better screen of the tablet.

Therefore I ordered a 101 G9 250HD, which was specified within the shop with 1.5 GHz.
I assumed it being an OMAP4460, which should do the trick.
Within the last days the store of my choice changed its product description to 1.2 GHz.

Now I am a bit confused about this "non turbo" versions and think of cancelling the preorder.
A OMAP4430 will not be able to play the camcoder files.
Am I right?

Is it more HD than big bug bunny 1080P h264?

My gen9 101 does a perfect job on big bug bunny.

The only difference that I've seen in regards to video between the two is that the 4430 can only encode/decode stereoscopic 3D at 720p, and the 4460 can encode/decode stereoscopic 3D 1080p.

Quote:
IVA 3 Hardware accelerator
Delivers true 1080p multi-standard HD
record and playback with the industryÔÇÖs
broadest support for multimedia codecs
available today as well as programmability
to add support for future codecs
Provides support for high deἀnition
stereoscopic 3D encode/decode
(OMAP4430: 720p, OMAP4460: 1080p)

http://www.ti.com/lit/ml/swpt034b/swpt034b.pdf - Page 2 "OMAP 4 application processors"

The other video specifications don't seem to change at all between the two. I may be wrong, but I'm not sure where the idea that the 4460 can play 1080p60 playback came from. As far as I can tell from all the documentation from TI, that statement is not correct.

Per this chart ( located on page 3 here http://www.ti.com/lit/wp/swpy021/swpy021.pdf ), there is no distinction between what the two can playback for 2D video playback.
(Text from the bottom of page 2 before the chart)
Quote:
To complement and work with the IVA hardware accelerator, TI offers the industryÔÇÖs broadest list of video
codecs supporting 1080p resolution at 30 frames-per-second and programmable support
for the following:
ÔÇó MPEG4 ASP
ÔÇó H.264 HP
ÔÇó VC-1 AP
ÔÇó RealVideo 10
ÔÇó ON2 VP7
ÔÇó AVS 1.0
ÔÇó DivX 6
ÔÇó Sorenson Spark v1


Image

As you can see, it clearly shows 1080i60 for a few types, but most only have 1080p30.
(Information about camcorders and such has been left off of this cut image, but is available on the pdf that is linked above.)

If you're looking for 1080p50 support, you won't have any luck from what I've seen in the TI documentation.

Thank you for the link.
You are right.
In the official documentation I see only "IVA 3 delivers up to 1080p at 30-frames per second".
I see no hint that 4460 is stronger there.

I guess I have to be more carefully with hoax messages.
