I still remember a time when the Tegra 3 – or “Kal-El” – processor was but a twinkle in Nvidia’s eye. It was debuted, I think, in the Asus Eee Pad Transformer Prime at the end of 2011.
Now we’re looking forward to the Tegra 4 – or “Wayne” (as in Bruce) – processor, and a leaked slide from outta China claims to have all the details.
The Tegra 4 leak appears initially over on a Chinese forum thingy called Chip Hell (via Weibo). Fortunately for you and me, the leaked Tegra 4 slide is in English. Phe-ew!
The Cortex A15-based Tegra 4 will adopt the same core formation as the Tegra 3, so that’s a “4-PLUS-1” setup, with the fifth being a “battery saver core”.
As for Tegra 4 graphics, a whopping 72 cores equates to 20x Tegra 2 and 6x Tegra 3. That’s a lot of cores. Under ‘Video’, we’re promised Full 1440p video encoding and decoding, while ‘Display’ mentions 2560 x 1600 resolutions, and 1080p at 120Hz.
As for input/output stuff, Tegra 4 supposedly welcomes USB 3.0, and, er, a small handful of things obscured by watermarks.
We expect to learn more about Tegra 4 at CES and/or MWC, with the first Tegra 4 devices probably hitting the market before 2013 is out.
