NVIDIA tonight showed a reference tablet design that it hows shows the potential of its dual-core Tegra 250 chipset. The design, made by Foxconn, should be a "generation ahead" of the iPad as it runs at the same 1GHz clock speed but uses a newer ARM Cortex-A9 architecture that's theoretically 25 percent more powerful per core than the iPad's Cortex-A8. The design has about 1GB of RAM, or four times as much as Apple's tablet.
