Nvidia's Kal-El quad-core ARM processor seems to be quite popular among tablet manufacturers since after Asus used it for the Transformer Prime, HTC is also reportedly interested in using this chip in an Android tablet of its own that will arrive in 2012.
The yet unnamed tablet will most probably come with an 10-inch display and according to DigiTimes
will be unveiled in February of 2012 during the Mobile World Congress (MWC).
Despite the early announcement is seems like the device won't actually arrive in retail until Q3 2012, shortly before Microsoft introduces its Windows 8 operating system, which also has an ARM port.
Outside of the Asus Transformer Prime and this upcoming HTC tablet, Acer also seems to prepare a Tegra 3 powered offering, so it seems like Nvidia
is having great success with Kal-El.
How will the Nvidia's SoC perform in real-life is however still unknown, and we have to wait for the Prime to arrive to get our first feel of a quad-core Android tablet.
