Intel to debut Dothan on Monday

The 90nm Pentium M ready for launch at last


Intel will launch its 90nm Pentium M processor, codenamed 'Dothan' next Monday, 10 May, sources close to the company have confirmed.

As yet there's no confirmation of the launch's details. However, Intel is still expected to unveil three 90nm Pentium Ms, clocked at 1.7GHz, 1.8GHz and 2GHz. The chips will carry the model numbers 735, 745 and 755, and be priced at $294, $423 and $637, previous reports have suggested.

The launch will necessitate a price cut for the older, 130nm PMs, with the 1.5GHz, 1.6GHz and 1.7GHz parts falling to $209, $241 and $294 from today's $241, $294 and $423, respectively. Those reductions amount to cuts of 13.3 per cent, 18 per cent and 30.5 per cent, respectively.

At this stage, it's not clear whether Intel will offer 533MHz frontside bus support or stick with the 400MHz FSB used by today's PMs. Circumstantial evidence from third-parties suggests it might, but the quoted clock speeds point to a 400MHz FSB for now.

In June, Intel is expected to release the Pentium M 715 and 725, presumably at 1.5GHz and 1.6GHz, matching 90nm parts to their 130nm predecessors, paving the way for the elimination of the 130nm chips altogether.

However, a full-scale revampt of the Centrino platform is not expected until the autumn, when Intel will release 'Sonoma', which comprises Dothan, the 'Calexico 2' tri-mode WLAN card and 'Alviso', the successor to the i855 chipset at the heart of Centrino. Alviso will introduce the 533MHz FSB to Dothan.

Dothan will double the current Pentium M cache size to 2MB and feature a number of architectural tweaks. ®

  • Twitter founder Dorsey beats hasty retweet from the board
    As shareholders sue the social network amid Elon Musk's takeover scramble

    Twitter has officially entered the post-Dorsey age: its founder and two-time CEO's board term expired Wednesday, marking the first time the social media company hasn't had him around in some capacity.

    Jack Dorsey announced his resignation as Twitter chief exec in November 2021, and passed the baton to Parag Agrawal while remaining on the board. Now that board term has ended, and Dorsey has stepped down as expected. Agrawal has taken Dorsey's board seat; Salesforce co-CEO Bret Taylor has assumed the role of Twitter's board chair. 

    In his resignation announcement, Dorsey – who co-founded and is CEO of Block (formerly Square) – said having founders leading the companies they created can be severely limiting for an organization and can serve as a single point of failure. "I believe it's critical a company can stand on its own, free of its founder's influence or direction," Dorsey said. He didn't respond to a request for further comment today.

  • Snowflake stock drops as some top customers cut usage
    You might say its valuation is melting away

    IPO darling Snowflake's share price took a beating in an already bearish market for tech stocks after filing weaker than expected financial guidance amid a slowdown in orders from some of its largest customers.

    For its first quarter of fiscal 2023, ended April 30, Snowflake's revenue grew 85 percent year-on-year to $422.4 million. The company made an operating loss of $188.8 million, albeit down from $205.6 million a year ago.

    Although surpassing revenue expectations, the cloud-based data warehousing business saw its valuation tumble 16 percent in extended trading on Wednesday. Its stock price dived from $133 apiece to $117 in after-hours trading, and today is cruising back at $127. That stumble arrived amid a general tech stock sell-off some observers said was overdue.

  • Amazon investors nuke proposed ethics overhaul and say yes to $212m CEO pay
    Workplace safety, labor organizing, sustainability and, um, wage 'fairness' all struck down in vote

    Amazon CEO Andy Jassy's first shareholder meeting was a rousing success for Amazon leadership and Jassy's bank account. But for activist investors intent on making Amazon more open and transparent, it was nothing short of a disaster.

    While actual voting results haven't been released yet, Amazon general counsel David Zapolsky told Reuters that stock owners voted down fifteen shareholder resolutions addressing topics including workplace safety, labor organizing, sustainability, and pay fairness. Amazon's board recommended voting no on all of the proposals.

    Jassy and the board scored additional victories in the form of shareholder approval for board appointments, executive compensation and a 20-for-1 stock split. Jassy's executive compensation package, which is tied to Amazon stock price and mostly delivered as stock awards over a multi-year period, was $212 million in 2021.

  • Confirmed: Broadcom, VMware agree to $61b merger
    Unless anyone out there can make a better offer. Oh, Elon?

    Broadcom has confirmed it intends to acquire VMware in a deal that looks set to be worth $61 billion, if it goes ahead: the agreement provides for a “go-shop” provision under which the virtualization giant may solicit alternative offers.

    Rumors of the proposed merger emerged earlier this week, amid much speculation, but neither of the companies was prepared to comment on the deal before today, when it was disclosed that the boards of directors of both organizations have unanimously approved the agreement.

    Michael Dell and Silver Lake investors, which own just over half of the outstanding shares in VMware between both, have apparently signed support agreements to vote in favor of the transaction, so long as the VMware board continues to recommend the proposed transaction with chip designer Broadcom.

  • Perl Steering Council lays out a backwards compatible future for Perl 7
    Sensibly written code only, please. Plus: what all those 'heated discussions' were about

    The much-anticipated Perl 7 continues to twinkle in the distance although the final release of 5.36.0 is "just around the corner", according to the Perl Steering Council.

    Well into its fourth decade, the fortunes of Perl have ebbed and flowed over the years. Things came to a head last year, with the departure of former "pumpking" Sawyer X, following what he described as community "hostility."

    Part of the issue stemmed from the planned version 7 release, a key element of which, according to a post by the steering council "was to significantly reduce the boilerplate needed at the top of your code, by enabling a lot of widely used modules / pragmas."
