Samsung Galaxy S4 could be delayed due to processor issues

Eager Samsung fans may have to exercise a little patience, as the company's forthcoming Galaxy S4 handset - originally rumoured for a 14 March launch - could be be delayed due to an unexpected hardware issue, according to a Piper Jaffray analyst.

Samsung's Exynos 5 Octa processor, which the South Korean giant unveiled at CES 2013, is said to be suffering from power issues that may have prompted the company to approach Qualcomm to supply the S4's processor instead.

Qualcomm's new quad-core Snapdragon 600 chip currently powers the newly announced HTC One, and runs even faster than the still-formidable Snapdragon S4 Pro processor in Sony's Xperia Z.

"We believe the S4 is being delayed primarily due to power issues with the company's eight-core Exynos Octa [...] the company is likely to shift more to external sources. We believe QCOM will pick up more of Samsung's S4 business," said Piper Jaffray analyst Gus Richard.

Meanwhile, some speculation suggests Samsung could stick with its eight-core Exynos 5 Octa processor for non-LTE variants of the S4, but adopt the quad-core Qualcomm chip for the 4G version of the handset.
