iPhone 8: Apple has CPU cycles to burn

A referee would have stopped this fight


While the iPhone 8 retains the same unremarkable design for the fourth year running, the internals are a different story. Thanks to extraordinary improvements in semiconductor design, it has been able to shrink the capacity and size of its battery pack, while opening up a significant performance lead over Qualcomm and Samsung.

Apple's TSMC-fabbed 10nm FinFET six-core 64-bit ARM-compatible CPU A11 in the iPhone 8 is now complemented, for the first time, by a fully Apple-designed GPU. The iPhone X is getting the same "Bionic" system-on-chip.

The hardware can now support 4K at 60 frames per second and 1080p video at 240 FPS. Top consumer camcorders costing around $1,000 from Sony and Panasonic can't match either frame rate. They don't even come close.

Last year Apple extended its benchmark lead over Samsung; in single core tests, the 2015 A9-powered Apple iPhone 6s outpaced Samsung's 2016 Galaxy S7.

But this year it has simply become embarrassing.

On Geekbench 4, tests conducted by Tom's Guide show the iPhone 8 is 54 per cent faster than the Galaxy Note 8 (which uses Samsung's own silicon), and the OnePlus 5 (which uses Qualcomm's Snapdragon 835, the choice of many Android flagships). The new iPhone 8 also comfortably outperforms laptops: a 13-inch MacBook Pro and a Dell XPS 13.

On the 3D Mark benchmark, the lead over Qualcomm and Samsung silicon is almost 2x. Exporting a two-minute 4K video clip took the Galaxy S8+ four minutes seven seconds, the Galaxy Note 8 three minutes and three seconds, and the iPhone 8 just 42 seconds.

It's worth noting that these tests are bursty. Because of thermal issues a mobile chip will not be able to conduct CPU-intensive tasks for long. But in a mobile-first world, the desktop is being left far behind. ®

  • Talos names eight deadly sins in widely used industrial software
    Entire swaths of gear relies on vulnerability-laden Open Automation Software (OAS)

    A researcher at Cisco's Talos threat intelligence team found eight vulnerabilities in the Open Automation Software (OAS) platform that, if exploited, could enable a bad actor to access a device and run code on a targeted system.

    The OAS platform is widely used by a range of industrial enterprises, essentially facilitating the transfer of data within an IT environment between hardware and software and playing a central role in organizations' industrial Internet of Things (IIoT) efforts. It touches a range of devices, including PLCs and OPCs and IoT devices, as well as custom applications and APIs, databases and edge systems.

    Companies like Volvo, General Dynamics, JBT Aerotech and wind-turbine maker AES are among the users of the OAS platform.

  • Despite global uncertainty, $500m hit doesn't rattle Nvidia execs
    CEO acknowledges impact of war, pandemic but says fundamentals ‘are really good’

    Nvidia is expecting a $500 million hit to its global datacenter and consumer business in the second quarter due to COVID lockdowns in China and Russia's invasion of Ukraine. Despite those and other macroeconomic concerns, executives are still optimistic about future prospects.

    "The full impact and duration of the war in Ukraine and COVID lockdowns in China is difficult to predict. However, the impact of our technology and our market opportunities remain unchanged," said Jensen Huang, Nvidia's CEO and co-founder, during the company's first-quarter earnings call.

    Those two statements might sound a little contradictory, including to some investors, particularly following the stock selloff yesterday after concerns over Russia and China prompted Nvidia to issue lower-than-expected guidance for second-quarter revenue.

  • Another AI supercomputer from HPE: Champollion lands in France
    That's the second in a week following similar system in Munich also aimed at researchers

    HPE is lifting the lid on a new AI supercomputer – the second this week – aimed at building and training larger machine learning models to underpin research.

    Based at HPE's Center of Excellence in Grenoble, France, the new supercomputer is to be named Champollion after the French scholar who made advances in deciphering Egyptian hieroglyphs in the 19th century. It was built in partnership with Nvidia using AMD-based Apollo computer nodes fitted with Nvidia's A100 GPUs.

    Champollion brings together HPC and purpose-built AI technologies to train machine learning models at scale and unlock results faster, HPE said. HPE already provides HPC and AI resources from its Grenoble facilities for customers, and the broader research community to access, and said it plans to provide access to Champollion for scientists and engineers globally to accelerate testing of their AI models and research.
