Mobile processors in cellphones and tablet computers continue to provide most of the growth in overall microprocessor sales, but other MPUs used in PCs, servers, and embedded applications are forecast to pull out of a two-year slump and increase 3% in 2014 to $42.5 billion from $41.2 billion in 2013.
Cellphone application processor sales are forecast to grow 19% in 2014 to a record-high $19.3 billion, while tablet processors are projected to climb 35% to a new all-time peak of $4.9 billion.
Cellphone application processors are forecast to account for 29% of worldwide microprocessor sales in 2014, while tablet MPUs will reach 7% of the total.
Microprocessors used in standard PCs, servers, large computers, and embedded applications are expected to represent 64% of total MPU sales in 2014.
By 2018, cellphone application processors are expected to represent 33% of the total microprocessor sales, while tablet MPUs will be 9% and the large PC/server/embedded segment will shrink to 58%.
Revenues for microprocessors in PCs, servers, large computers, and embedded systems fell 2% in 2013 after dropping 6% in 2012.
These back-to-back declines were partly a result of PCs being superseded by tablet computer and smartphone sales, but also due to cutbacks in IT spending by businesses in the past two years.
In 2013, shipments of PCs (desktops and notebooks) built with x86 MPUs from Intel and AMD suffered the worst decline ever, falling by about 9% to 315 million units worldwide.
A projected 2% increase in PC unit sales in 2014, along with improved IT spending by businesses and stronger growth in embedded-processor applications, will enable the PC/server/embedded MPU market segment to grow again this year, but it will not set a new record high until 2015, when revenues are forecast to grow 6% to $45.2 billion.
This large MPU market segment will grow by a CAGR of 4.0% between 2013 and 2018, reaching $50.1 billion in the final year of the forecast.
Meanwhile, sales of cellphone application MPUs (which exclude baseband processors used in wireless modems) are expected to grow by a CAGR of 12.5% in the five-year forecast period, climbing to $29.1 billion in 2018.
Tablet processor sales are forecast to rise by a CAGR of 16.1%, reaching $7.7 billion in 2018. Total microprocessor sales are projected to rise by an annual rate of 7.4% in the forecast period to $87.0 billion in 2018.
