What is the Difference Between NVIDIA Tegra 2 and Tegra 3?

The NVIDIA Tegra 2 and Tegra 3 are both system-on-chip (SoC) processors designed for mobile devices, but they have some key differences in terms of performance, features, and capabilities. Here are the main differences between NVIDIA Tegra 2 and Tegra 3:

1. CPU: Tegra 3 is based on ARM's Cortex-A9 architecture, while Tegra 2 uses ARM's Cortex-A9 MPCore architecture.
2. GPU: The GPU in Tegra 3 is an evolution of the Tegra 2 GPU, with 4 additional pixel shader units and a higher clock frequency. It also supports higher video resolutions, up to 2560x1600, and various video formats, including 1080p MPEG-4 AVC/h.264 40 Mbit/s VC1-AP, and simpler forms of MPEG-4 such as DivX and Xvid.
3. NEON: Tegra 3 is the first Tegra release to support ARM's SIMD extension, NEON, which can provide performance improvements in certain tasks.
4. Memory: Tegra 2 has both L1 cache (instruction and data – private for each CPU core) and L2 cache (shared and that allow packing up to 1GB DDR2 memory modules). Tegra 3 also supports LPDDR2 memory and can address more than 4GB of RAM, providing increased performance and the ability to run 64-bit apps.

In summary, the NVIDIA Tegra 3 offers better performance and capabilities compared to the Tegra 2, thanks to its improved CPU and GPU architecture, support for NEON instructions, and higher memory capacity.
