Details on the next generation Tegra 4 processor, codenamed "Wayne", leak

NVIDIA has done pretty well on the mobile market with its Tegra 3 processor, and it should be of no surprise to anyone that NVIDIA has been working on the next generation Tegra processor. The company even provided some rough details early last year.
However, some detailed information on the next-generation 28nm Tegra 4 leaked today, and it promises six times the power of Tegra 3. Tegra 4 appears to be, according to a leaked slide, a 4+1 quad-core design similar to that of the current Tegra 3. The Cortex-A15-based Tegra 4 has 72 graphics cores and supports dual channel memory. Tegra 4 will also support resolutions of 2560 x 1440 for encode and decode and promises very low power consumption.

Other supported features will include the USB 3.0, making this the first NVIDIA chipset to support the new and faster USB standard.

With CES 2013 kicking off in mere weeks, we should have significantly more details coming in the not-too-distant future.

New 10" tablet res?

That reference to a 1440p video decoder hints at the new target res for tablets. Will it be a 10" tablet at 2560X1440, or will tablets get slightly larger, perhaps to a 11.2" or something similar?

I'm not yet ready to replace my Galaxy Tab 10.1, but I could change my mind at that res with this chip.

Google's Nexus 10 already has a 2560x1600 resolution, so they wouldn't even have to get bigger to justify 1440p decoding.

Really? I didn't know it had such a high res. That's cool.

Boosting to that kind of resolution on a 10" screen is pointless. Your pixel density will be so great that it will not only require an excessive amount of graphics power, but will also require a significantly more intense backlight to achieve the same brightness levels as lower resolution screens. You could easily lose an hour or more of your battery life to do the same amount of work.

Yeah but it makes reading a lot nicer to have high dpi.
