Freescale to launch 90nm PowerPC G4 today

MPC7448 to take Apple notebooks to next level?

Motorola's erstwhile chip division, Freescale, is expected to launch its latest G4-class processor, the MPC7448, today at its Smart Networks Developer Forum, being held this week in Frankfurt.

The new chip is Freescale's first 90nm G4 and is based on the company's e600 core, the foundation for Freescale's upcoming line of dual-core chips. The 7448, however, contains just one core, clocked to beyond 1.5GHz. It contains 32KB of L1 cache and 1MB of L2, double the 512KB of L2 found in the MPC7447A currently driving Apple's PowerBook G4 and iBook G4 notebooks.

Indeed, the 7448 is likely to provide Apple with its next notebook speed bump, as the company struggles to fit the hot-running PowerPC 970FX - aka the G5 - into a laptop.

However, it will have to wait: the 7448 is not expected to sample until H1 2005, Freescale said.

Unlike other e600-derived chips, the 7448 lacks an integrated memory controller. Instead, it talks to a North Bridge chip across a 200MHz MPX frontside bus, up from the 7447A's 167MHz. That's presumably for better compatibility with existing G4-based systems and, indeed, the 7448 and 7447A are pin-compatible.

The 90nm 7448 provides 0.9, 1.0 and 1.1V operating voltages, yielding power dissipation of 10W at 1.4GHz, Freescale claims, with compares well with the 7447A's typical and maximum dissipation figures of 21W and 30W, respectively, at 1.4GHz.

While the 7448 is clearly geared toward existing G4 roles, the dual-core MPC8641D, also based on the e600 core, is targeted at embedded applications. Each core has its own 1MB L2 cache and AltiVec SIMD engine, and the chip also features a dual 64-bit DDR 2 memory controlled clocked at up to 667MHz with ECC. The chip also contains two PCI Express 1x-8x bus controllers and a 1x/4x Rapid IO bus controller. The dual-core part uses a 960-pin interface.

Cunningly, the 8641D can not only appear to the host OS as two processors, but is capable of running a separate operating systems on each core.

The 8641D - and a single core version, the MPC8641 - will sample H2 2005. ®

    DuckDuckGo promises privacy to users of its Android, iOS browsers, and macOS browsers – yet it allows certain data to flow from third-party websites to Microsoft-owned services.

    Security researcher Zach Edwards recently conducted an audit of DuckDuckGo's mobile browsers and found that, contrary to expectations, they do not block Meta's Workplace domain, for example, from sending information to Microsoft's Bing and LinkedIn domains.

    Specifically, DuckDuckGo's software didn't stop Microsoft's trackers on the Workplace page from blabbing information about the user to Bing and LinkedIn for tailored advertising purposes. Other trackers, such as Google's, are blocked.

  • Despite 'key' partnership with AWS, Meta taps up Microsoft Azure for AI work
    Someone got Zuck'd

    Meta’s AI business unit set up shop in Microsoft Azure this week and announced a strategic partnership it says will advance PyTorch development on the public cloud.

    The deal [PDF] will see Mark Zuckerberg’s umbrella company deploy machine-learning workloads on thousands of Nvidia GPUs running in Azure. While a win for Microsoft, the partnership calls in to question just how strong Meta’s commitment to Amazon Web Services (AWS) really is.

    Back in those long-gone days of December, Meta named AWS as its “key long-term strategic cloud provider." As part of that, Meta promised that if it bought any companies that used AWS, it would continue to support their use of Amazon's cloud, rather than force them off into its own private datacenters. The pact also included a vow to expand Meta’s consumption of Amazon’s cloud-based compute, storage, database, and security services.

    IT services biz Atos has introduced a suite of cloud-based high-performance computing (HPC) services, based around technology gained from its purchase of cloud provider Nimbix last year.

    The Nimbix Supercomputing Suite is described by Atos as a set of flexible and secure HPC solutions available as a service. It includes access to HPC, AI, and quantum computing resources, according to the services company.

    In addition to the existing Nimbix HPC products, the updated portfolio includes a new federated supercomputing-as-a-service platform and a dedicated bare-metal service based on Atos BullSequana supercomputer hardware.
