Chipmaker Intel expects its German sales volumes to rise more than 10 percent this year as it launches new energy-saving processors and as Microsoft launches a new version of its Windows computer operating system.

That (launch of Windows 8) will lead to a demand boost among retail customers, the head of Intel's German business, Christian Lamprechter, told Reuters on Tuesday.

Lamprechter said he was also banking on demand for the new Ultrabook category of super-thin PCs, which will be equipped with Intel's new Ivy Bridge chip technology, designed to consume less energy.

Intel's sales volumes in Germany have grown 4-6 percent per annum in previous years.
