Yesterday, we got an eyeful of NVIDIA's new Tegra 4 and Tegra 4i, along with the Phoenix, NVIDIA's nifty reference device. The benchmarks were quite impressive compared to current-generation processors, but all we got to see in terms of gaming performance was a brief demo of Real Boxing.

In a video posted today to NVIDIA's YouTube channel, the chip maker shows off a "Tegra 4 enhanced Zombie Driver," side by side with the same game running on a "non-Tegra 4" device. The difference (as with many Tegra-enhanced games) is night and day. The video puts on full display Tegra's dynamic shadows and lighting, textural enhancements, and overall finesse. Take a look for yourself.

As a reminder, NVIDIA's answer to when we'll first start seeing these chips is a rough "Q2," so while the chip's performance looks great, we've got a while to wait yet before seeing these in new phones and tablets.
