I guess its nice, but it sort of seems unimpressive from where I sit. All the other people making A9s just use a 45nm low power process and are able to clock their chips up past 1GHz just fine. NVidia has to use a normal process to get their 4 main cores past 1GHz, and the single A9 they have on LP silicon is clocked way lower. ARM's proposed tandem between A7 and A15 cores seems much more interesting.

Can somebody confirm that it doesn't have wireless (GSM, CMDA, LTE, 802.x, etc.) integrated? This would make it different to the Snapdragon, OMAP, A5 etc. system-on-chip

A5 and OMAP don't have 3G/4G integrated in them. A5 uses Qualcomm's 3G chip. Having a 3G chip integrated is more of an exception in the industry, not the rule. Although everyone seems to be moving in that direction right now. Nvidia also bought a company recently to integrate LTE in their chips in the near future.

Qualcomm has an easier time integrating the modems for one simple reason: they make them. Can't think of many other SoC vendors that also make their own modems (maybe Samsung?).

st-ericsson's novathor seems to be stealing a good bit of market share from Qualcomm in upcoming phones.

This version doesn't, but a future Tegra will integrate an Icera baseband.

Funny - first thing I thought as well. But the video decoder is just h.264 up to high profile, so it should, in theory, work for html5 video as well

I would've thought chip makers would decode WebM, too, by now. Google won't stay on h.264 forever.

They do, Tegra 2, 3 and OMAP4 decode VP8 in hardware.

What strikes me is that this could compete with current generation game consoles, so next gen consoles might be Tegra "Wayne" (from Wikipedia) : Processor: quad- or octa-core ARM Cortex-A15 MPCore Improved 24 (for the quad-core) and 32 to 64 (for the octa-core) GPU cores with support for Directx 11+, OpenGL 4.X, OpenCL 1.X, and Physx 28 nm[23] About 10 times faster than Tegra 2 This would be low-power/low-cost game c…

Was just hopping in here to post this -- Xbox.next got named (Loop for now) and details leaked about how it is an ARM-based design with dedicated chips for each major process used in modern gaming (video, physics, audio, etc.)[1]

After seeing the specs on the Tegra 3, I can't help but think that Tegra 3++ or "Tegra 4" will basically by the Xbox-next.
