Nvidia and Qualcomm have already laid their cards on the table in their bid for top dog status in the mobile processor game over the next 12 months, dishing up their Tegra 3 and Snapdragon S4 chips at Mobile World Congress last month.
But things are reportedly already going wrong in the Qualcomm camp with news that the company's manufacturing partner TSMC has hit delays.
SemiAccurate reports that TSMC has halted production of 28nm chips, and is unlikely to get things going again before the end of this month.
At this point it's not clear just what the issue is, or how widespread it is – Qualcomm itself isn't saying. That said, you'd expect that if the problem was only a minor one the best thing to do would be to say so quickly before word started to spread.
Among the new handsets announced recently that are expected to have the Snapdragon S4 on board when they go on sale are some variants of the HTC One S and One X, the Panasonic Eluga and the Asus Transformer Pad 300.
That doesn't really match up to the strength of the Tegra 3 camp at present, so for Qualcomm's sake we're hoping that what is already an uphill struggle doesn't become an impossible one.
