I don't have any links, but NVIDIA basically said they opted out of NEON for space reasons with the first two Tegra phases. And from further reading, latency and performance testing between NEON and non-NEON seems to conclude: non-NEON equals crippled under certain conditions.

I've done a bit of reading on NEON and I'm curious how often it's used. Certainly it seems useful, but even ARM seems to be heavily pushing the media [de|en]code capabilities of this SIMD implementation which is something that may very well be handled by a DSP (though in a much less generalized way). But is it generally used outside of this?

Does anyone have links to NVIDIAs rational for leaving NEON out (beyond space savings)?

space, cost, and they probably have a pretty good gpu and it will be fine for graphics without neon, including video decoding to supported codecs.
not sure what happens if you try and do some post processing or use an unsupported codec though...

Yes, I worded that poorly - I meant it in the sense that there is no systematic, easy way to balance the core-usage of single applications, and considering that for quite some time single core is going to be the prevalent hardware, pushing people to actively increase thread/process count will mean overhead and an extra source of bugs. You can, of course, do it (well even

) if you're a good coder, but that's you, not the OS. On the bright side, the availability of such hardware might spark a little mobile-oriented platform innovation (on desktops it didn't really matter to have balanced-out core usage so not much research went that way).

Nvidia shows its 'Kal-el' quad-core A9 at GDC 2011.

Wow. Nvidia is agressive, and it looks as if the next Tegra is going to be a monster.

Here is Anandtech's take of the next Tegra!

It seems that devices may have this as early as August of this year!

http://www.anandtech.com/show/4181/n...lets-this-year

Yep, in only 5 months, we may be seeing an ultra-mobile quad-core SoC with performance comparable to Core2Duo's (according to Nvidia)!

If true, this will certainly offer performance comparable to ATOM and usher in a new wave of laptops, and tablet apps capable of replacing legacy x86.

I don't know about you, but an ultra-thin laptop that has 12hour battery life sounds pretty enticing! Even a tablet with a keyboard dock, or a BT keyboard/mouse will be enticing.

Expect Android, Ubuntu, and possibly MeeGo to lead the charge in this radical productivity paradigm shift.

While Android allows for mouse/keyboard, traditional linux has (I'm assuming) better productivity support. But with the fast development of Android, and many services being pushed through the web, an Android tablet may be quite competent for productivity.

Oh, brave new world!
