Tegra 2 is the only Cortex A9 based dual-core chip that is actually shipping and you can even buy some products based on it. Texas Instruments OMAP 4430 Cortex A9 based dual-core chip clocked at 1GHz is also supposed to ship in Q1 2011 in USA, inside the RIM Playbook Blackberry tablet.
It gets more interesting as Texas instrument already announced a faster iteration of the Cortex A9 based dual-core chip, this time clocked at 1.5GHz. The company calls it the OMAP 4440 and it is again a 45nm chip. Just as TI 4430 it plays 1080P in HD in 2D video but in can also play 1080P in Stereoscopic 3D video. The 1GHz clocked TI4430 can only support 720P Stereoscopic 3D video.
The 1.5GHz clock also brings support for 12Mpixel stereo camera, and of course you will need two cameras for that. In comparison, TI4430 clocked at 500MHz slower speed can only cope with 5MegaPixel 3D camera.
We can expect that graphics based on PowerVR 540 core at 1.5 GHz also gets tremendously faster. PowerVR 540 core should be three to four times faster than PowerVR 530 core, but we will try to get some real numbers.
We reckon that TI 4440 can show its face later this year, and it is kind of natural to expect that Nvidia and other ARM players can do the same 1.5GHz clock if not even higher.
