Intel gives Broadwells and Haswells their Meltdown medicine

Chipzilla and Oracle are working their way back through time to deliver fixes


Intel slipped out a new Microcode Update Guidance on Monday, revealing that lots of Haswell and Broadwell Xeons can now receive inoculations against the Meltdown and Spectre CPU design flaws.

The new document (PDF) says Broadwell processors with CPUIDs 50662, 50663, 50664, 40671, 406F1, 306D4 and 40671 are ready for their reaming.

Updates for Haswells numbered 306C3, 4066, 306F2, 40651 and 306C3 have also hit production.

The CPUs mentioned above include Xeon and Core silicon.

Broadwell debuted in 2014 and Haswell the year before, so these updates show Intel is working backwards through its catalog. The Update Guidance also lists 16 processor types for which Intel is still in the planning stage, meaning Intel has no schedule for delivering a fix. The affected CPUs are mostly oldies. A further 9 CPU types are listed as "Pre-beta", meaning microcode is being tested by partners under non-disclosure agreements.

Oracle's also visited its past in the pursuit of Meltown/Spectre patches: late last week it offered patches for version 5.x of its Linux. ®

  • Intel is running rings around AMD and Arm at the edge
    What will it take to loosen the x86 giant's edge stranglehold?

    Analysis Supermicro launched a wave of edge appliances using Intel's newly refreshed Xeon-D processors last week. The launch itself was nothing to write home about, but a thought occurred: with all the hype surrounding the outer reaches of computing that we call the edge, you'd think there would be more competition from chipmakers in this arena.

    So where are all the AMD and Arm-based edge appliances?

    A glance through the catalogs of the major OEMs – Dell, HPE, Lenovo, Inspur, Supermicro – returned plenty of results for AMD servers, but few, if any, validated for edge deployments. In fact, Supermicro was the only one of the five vendors that even offered an AMD-based edge appliance – which used an ageing Epyc processor. Hardly a great showing from AMD. Meanwhile, just one appliance from Inspur used an Arm-based chip from Nvidia.

  • TSMC may surpass Intel in quarterly revenue for first time
    Fab frenemies: x86 giant set to give Taiwanese chipmaker more money as it revitalizes foundry business

    In yet another sign of how fortunes have changed in the semiconductor industry, Taiwanese foundry giant TSMC is expected to surpass Intel in quarterly revenue for the first time.

    Wall Street analysts estimate TSMC will grow second-quarter revenue 43 percent quarter-over-quarter to $18.1 billion. Intel, on the other hand, is expected to see sales decline 2 percent sequentially to $17.98 billion in the same period, according to estimates collected by Yahoo Finance.

    The potential for TSMC to surpass Intel in quarterly revenue is indicative of how demand has grown for contract chip manufacturing, fueled by companies like Qualcomm, Nvidia, AMD, and Apple who design their own chips and outsource manufacturing to foundries like TSMC.

  • Intel withholds Ohio fab ceremony over US chip subsidies inaction
    $20b factory construction start date unchanged – but the x86 giant is not happy

    Intel has found a new way to voice its displeasure over Congress' inability to pass $52 billion in subsidies to expand US semiconductor manufacturing: withholding a planned groundbreaking ceremony for its $20 billion fab mega-site in Ohio that stands to benefit from the federal funding.

    The Wall Street Journal reported that Intel was tentatively scheduled to hold a groundbreaking ceremony for the Ohio manufacturing site with state and federal bigwigs on July 22. But, in an email seen by the newspaper, the x86 giant told officials Wednesday it was indefinitely delaying the festivities "due in part to uncertainty around" the stalled Creating Helpful Incentives to Produce Semiconductors (CHIPS) for America Act.

    That proposed law authorizes the aforementioned subsidies for Intel and others, and so its delay is holding back funding for the chipmakers.

  • Intel demands $625m in interest from Europe on overturned antitrust fine
    Chip giant still salty

    Having successfully appealed Europe's €1.06bn ($1.2bn) antitrust fine, Intel now wants €593m ($623.5m) in interest charges.

    In January, after years of contesting the fine, the x86 chip giant finally overturned the penalty, and was told it didn't have to pay up after all. The US tech titan isn't stopping there, however, and now says it is effectively seeking damages for being screwed around by Brussels.

    According to official documents [PDF] published on Monday, Intel has gone to the EU General Court for “payment of compensation and consequential interest for the damage sustained because of the European Commissions refusal to pay Intel default interest."

  • Intel demos multi-wavelength laser array integrated on silicon wafer
    Next stop – on-chip optical interconnects?

    Intel is claiming a significant advancement in its photonics research with an eight-wavelength laser array that is integrated on a silicon wafer, marking another step on the road to on-chip optical interconnects.

    This development from Intel Labs will enable the production of an optical source with the required performance for future high-volume applications, the chip giant claimed. These include co-packaged optics, where the optical components are combined in the same chip package as other components such as network switch silicon, and optical interconnects between processors.

    According to Intel Labs, its demonstration laser array was built using the company's "300-millimetre silicon photonics manufacturing process," which is already used to make optical transceivers, paving the way for high-volume manufacturing in future. The eight-wavelength array uses distributed feedback (DFB) laser diodes, which apparently refers to the use of a periodically structured element or diffraction grating inside the laser to generate a single frequency output.

  • Intel to sell Massachusetts R&D site, once home to its only New England fab
    End of another era as former DEC facility faces demolition

    As Intel gets ready to build fabs in Arizona and Ohio, the x86 giant is planning to offload a 149-acre historic research and development site in Massachusetts that was once home to the company's only chip manufacturing plant in New England.

    An Intel spokesperson confirmed on Wednesday to The Register it plans to sell the property. The company expects to transfer the site to a new owner, a real-estate developer, next summer, whereupon it'll be torn down completely.

    The site is located at 75 Reed Rd in Hudson, Massachusetts, between Boston and Worcester. It has been home to more than 800 R&D employees, according to Intel. The spokesperson told us the US giant will move its Hudson employees to a facility it's leasing in Harvard, Massachusetts, about 13 miles away.
