What is the Difference Between Quad core Nvidia Kal-El (Tegra 3) and Nvidia Tegra 2?

The main difference between the Nvidia Tegra 3 (quad-core Kal-El) and the Nvidia Tegra 2 lies in the number of cores and the performance improvements that come with it. Here are the key differences:

1. Number of Cores: Tegra 2 is a dual-core SoC, while Tegra 3 is a quad-core SoC.
2. CPU Clock Speed: Each core in Tegra 2 is clocked at 1GHz, while each core in Tegra 3 is clocked at 1.5GHz.
3. GPU: Tegra 3's GPU has 12 core units, compared to Tegra 2's 8 core units, resulting in significantly better performance.
4. Video Decoder and Encoder: Tegra 3 has an improved video decoder that can accelerate 1080p H.264 high profile content at up to 40Mbps and a more efficient video encoder capable of 1080p H.264 base profile encode at 30 fps.
5. Image Signal Processor (ISP): The ISP in Tegra 3 is twice as fast as the one in Tegra 2.

Overall, Nvidia claims that Tegra 3 outperforms Tegra 2 by doubling the processing power and tripling the graphics processing power.
