Intel narrowed the bandwidth of its expectations for fourth-quarter revenue Thursday.

Revenue should fall between $10.4 billion and $10.6 billion during the quarter, said Andy Bryant, Intel's chief financial officer. The midpoint of this range, $10.5 billion, is the same as the range Bryant provided in October following Intel's third-quarter results. At that time, Intel expected to bring in between $10.2 billion and $10.8 billion in the final quarter.

Strong growth in emerging markets such as China and India, as well as the global adoption of notebook PCs over desktops, helped keep Intel's business expectations within the prescribed range, Bryant said.

Retail shopping strong

The fourth quarter of the calendar year is generally the best operating period for chip and PC companies, given the high volume of holiday shopping during November and December. Early reports of this year's holiday retail PC buying showed an improvement over last year, according to Current Analysis, and analysts had hoped Intel would receive an extra kick from that activity.

Intel is still having problems meeting demand for low-end desktop chipsets as a result of manufacturing capacity constraints, Bryant said. This problem is expected to go away over the next year as Intel rolls out its new 65-nanometre processing technology, which allows the company to make smaller transistors than the current 90nm generation of chip-making technology. This also frees up capacity on older manufacturing technologies for chipsets, which aren't as complicated as microprocessors, such as the Pentium D or Pentium M.

The manufacturing tightness has not affected processor shipments, Bryant said.

Streetfighting man: AMD v Intel

Bryant declined to provide specific details on chip pricing during the quarter but said Intel is facing strong competition for design wins, especially within the server market, against rival Advanced Micro Devices Inc. (AMD) "Server orders are tough to win, and it's hand-to-hand combat in some places," he said.

Likewise, Intel did not have data on its market share gains or losses during the quarter at this early date, Bryant said. But Intel's business performed as expected, and if AMD's business performed as that company expected, AMD would be likely to gain a little bit of share, he said.

Intel's midpoint revenue projection of $10.5 billion would give it about $39 billion in revenue for the full year, a 14 per cent to 15 per cent improvement over last year, Bryant said.
