Intel’s CPU supply problems have worsened, and it’s published an official apology, addressing the open letter to all its customers and partners. The apology follows a now-familiar theme – the CPU supply issues that have beset Intel for over a year – but doesn’t really offer anything more reassuring than the equally familiar “we’ve added production capacity.”

Michelle Johnston Holthaus, executive VP and GM of sales, marketing, and communications group, has signed the letter, fallen on the sword, and would “like to acknowledge and sincerely apologize for the impact recent PC CPU shipment delays are having on your business… Despite our best efforts, we have not yet resolved this challenge.”

It’s interesting the open letter has been signed by anyone other than Intel CEO, Bob “Robert” Swan. Especially after he had been so candid about the situation on an earnings call about the company’s recent, and perhaps surprisingly stellar, financial results. In that call he acknowledges it’s a problem and that it’s all a problem of increasing demand for Intel’s own best processors. Which can only be a good thing, right? Well…
