Heads have started to roll at AMD (AMD), as technology chief Phil Hester resigned with no replacement planned, according to the Wall Street Journal.

The news comes less than a week after the chipmaker announced a 15% sequential sales shortfall and plans to cut 10% of its staff due to weak demand across all its business segments.

AMD did not immediately respond to a request for comment.

Analysts point to a slowing economy and a critical delay of AMD’s quad-core Barcelona chip for the server market as two major reasons for the company’s current woes.

AMD, which has already pulled Hester’s bio from its Web site, called Hester the top executive “responsible for setting the architectural and product strategies and plans for AMD’s microprocessor business.”

The company is in a brutal battle with rival Intel (INTC) and has been on the losing end recently due to misfirings like the Barcelona glitch. AMD follows Intel’s earnings report Tuesday with its full first-quarter report on Thursday.

AMD shares were down a nickel to $6.22 in midday trading Friday.
