But why has Tegra had such an uphill battle?

Microsoft_Surface_RT-e1360270484638-300x227.jpgWhen Tegra 3 was introduced, the market spoke. It wasn’t impressed that Tegra 3 would require a separate cellular radio, a mismatch that was bound to cause compatibility issues. As such the chip did make it into the highly regarded HTC One X+, but didn’t make it into any of the year’s top ten smartphones. In the tablet world, it made it into the first run of the Nexus 7, the well-received but poor selling Microsoft Surface RT, and the under-appreciated Asus Transformer series. There were other wins, such as the Tesla Model S and the Ouya, but the Tegra has no iPhone 5 or Galaxy S3.

Chip watchers say it’s because Tegra only just started packing cellular connectivity into the system with Tegra 4 — albeit an unproven softmodem — while Snapdragon has a tried-and-true cellular radio. Others say that it’s because Tegra 3 was an underperforming and power-hungry part that didn’t meet benchmark claims, while competing platforms offered a much more economical total power draw (TDP).

In the case of Tegra 4, an apparent lack of interest could be because of the chip’s missing support for APIs such as DirectX, OpenCL, and OpenGL — without this support cross-platform development of graphics intensive software will be on the high side of difficult. And even if Tegra 4 stands on its own and performs well on early benchmarks, it still has to deal with stiff competition from chips like the Snapdragon 800. So far the most notable product that will use Tegra 4 is Nvidia’s own Project Shield.
