Nvidia Tegra 2 Processor Table PC

What is Nvidia Tegra 2
Tegra series is a system-on-chip developed by NVIDIA. Compare the first generation of Tegra (Tegra 1), which is based on ARM11 design, NVIDIA skipped ARM Cortex A8 design, and went straight to Cortex A9 design(faster that Cortex A8!)

.

Cortex A9 is expected to significantly outperform Cortext A8 based processors but currently no benchmark results exist to prove this yet (well, almost - read further). Currently no smartphones on the market are using Cortex A9 based processors. Future Cortex A9 based processors include 3rd generation Qualcomm processors, Samsung's Orion and Texas Instrument's OMAP 4 platform.

Tegra 2's GPU core is NVIDIA's own design. It is essentially the same design as the one found in Tegra 1, but faster. NVIDIA claims about 2-3x the performance improvement. I believe it since the bandwidth alone between the processor and the memory increased 2x.

They also claim far less power consumption when Tegra 2 chip is decoding music and video compare to Qualcomm's Snapdragon processors. If this is true, Tegra 2 based phones will last significantly longer when listening music and watching YouTube video.

So what makes Tegra 2 CPU core go fast? This is really asking a question of what makes ARM Cortex A9 fast. ARM has implemented out-of-order execution on its dual-issue pipeline. It also features a shorter pipeline which helps complete instructions faster. Cortex A9 is expected to feature significantly better IPC (instructions per clock) than Cortex A8. I

1GHz Cortex A9 core will perform significantly better than 1GHz Cortex A8 core (about 25% improvement!). And on top, Cortex A9 is known to clock well - up to 2GHz. However, whether NVIDIA can scale other components in Tegra 2 will be a separate question all together.

Comparison Between Cortex A9 and Cortex A8

1GHz dual-core Cortex A9 will destroy any 1GHz single-core Cortex A8 based processors. Also, NVIDIA's design can be extended to quad-core packaging. Eventually, we may see a quad-core Tegra 2 processors if there is a market for it.What we are seeing here, is essentially a repeat of the evolution of the desktop processors in a smaller, more efficient package.
