  • Another M2 Macbook performance article

    "Apple’s M2 chip found in the 13-inch MacBook Pro might struggle under pressure, found Vadim Yuryev of Max Tech on YouTube. The YouTuber tested the new MacBook Pro in order to see how it deals with extremely resource-heavy tasks."

    "This resulted in severe throttling upon hitting high temperatures, highlighting that Apple’s design choices for the laptop might not be ideal in terms of cooling."

    "Even though most users won’t require that kind of power from their new 13-inch MacBook Pro, it’s still bothersome that it can heat up to 108 degrees Celsius and that this results in severe throttling. Whether you should buy it largely depends on the
    kind of workloads you’re planning to engage in. It can probably handle all manner of computing, but as shown by the test, the extremes appear to be reserved for high-end Macs."

    "As for the M2 MacBook Pro, it seems to be having a bit of a rough start. Some reports pointed toward poor performance in various multitasking apps that are on the resource-heavy side, such as Photoshop, Final Cut Pro, and Lightroom. Other sources,
    including Max Tech, reported that the read and write speeds on the SSD in the 256GB version of the M2 MacBook Pro are much worse than those of its M1 predecessor. However, this problem only seems to apply to the entry-level version, and users who choose
    the option with more storage don’t suffer from this issue. It’s most likely linked to the fact that when all of the 8GB of Apple Unified memory has been used up, the M2 MacBook Pro dips into the 256GB reserve on the SSD and uses it as virtual memory."

    Which cites the same source...

    ...or didn't you notice that detail?

    "Even though most users won’t require that kind of power from their new 13-inch MacBook Pro, it’s still bothersome that it can heat up to 108 degrees Celsius and that this results in severe throttling. Whether you should buy it largely depends on

    And he specifically calls out that the "perfromance" [sic] issue of the
    SSD is only for an entry level machine with a 256GB SSD, which no
    "perfromance" [sic] user is ever going to choose.

    Performance doesn't matter when the chip itself is fatally flawed.

    Apple focuses only on advertising security without ever focusing on the necessary R&D required to deliver a chip that does NOT have fatal flaws.

    Given everyone, including bad actors, already know of the multiple
    unpatchable hardware flaws, the chip may be useful merely as a cheap toy
    but it's almost completely worthless in a corporate environment that cares about its security.

    The chip isn't fatally flawed.

    Until very recently, you insisted they weren't doing any chip design.

    Name a CPU that doesn't have flaws.

    'Design flaws in Intel’s processor chips stretching back to 1995 have
    opened vulnerabilities in devices running operating systems from
    Microsoft, Apple and Linux vendors. All Intel chips are affected by the
    flaws (dubbed “Meltdown” and "Spectre”), and at least one also affects some processors from AMD and ARM.'

    A list of all the major vulnerabilities that impact Intel processors.'

    'We know there are differences in how AMD and Intel implement
    speculative execution, so it was never clear how much of AMD’s apparent immunity was due to hardware design and how much was provided by
    “security through obscurity.” AMD, to its credit, never told the press
    that its CPUs were immune to attacks like Spectre and Meltdown, and it
    didn’t launch any major advertising campaigns around the idea that it represented the “safe” x86 choice. Good thing, too. Researchers have now found a Meltdown-equivalent attack that affects AMD processors.'

    'What is this security threat about?
    Two major vulnerabilities were found that seem to affect all major microprocessors, including Intel, AMD and ARM brand products. These
    weaknesses can be exploited by hackers to gain access to personal data
    reaching from passwords to credit card information stored from online transactions. A security team at Google has labeled the two flaws as
    "Spectre" and "Meltdown."'

    But don't worry, Arlen: I'm sure you'll find some way to turn this
    around and make it all Apple's fault.
