back to article Pick a core, any core, says Intel – we'll magically put the right workload onto one in a hybrid SoC or accelerator

Intel has revealed some details about its upcoming chip designs, and claims they are the biggest and most significant change to its products for years. This includes new CPUs and the Alder Lake family that places different types of core alongside each other in system-on-chip packages. The chip giant is kinda taking a leaf out …

    Reheated

    So Intel is trying yet again to sell us reheated vintage tech.

    Is it this time that consumers will fall for that?

    I read that the E cores are not really that efficient energy wise. Yes they can consume little power when working on a task, but the task will take longer time and likely consuming more power to complete than if it was run for a short time on a performance core.

    The main reason is that E cores are probably much cheaper to be made, so it costs very little to slap them on a substrate and it looks good on marketing sheets.

    Majority of consumers won't see the difference, but they will be able to brag how many cores they have.

    100 billion transistors

    How the hell does anyone ever keep track of that, let alone prove the design is correct?

      This is all modular and generated from a high level language. You can run tests suite against such designs just like a normal program.

        "You can run tests suite against such designs just like a normal program."

        Why don't Intel, then?

        More seriously: to some degree you can only test for the expected. Which is why normal programs have bugs even when using TDD and other methods to limit divergence from the spec. And as for whether the spec was right...

          “Just like a normal program”

          A normal program that compiles to 100 billion instructions.

      It is mostly synthesized, it is essentially "compiled" from a higher level language called VHDL.

      As for proving correctness, you prove it is correct the same way you prove that big operating systems like Linux, Windows, or macOS is correct - you don't. There are always bugs, you just hope your test suites catch anything that matters, but you're screwed when someone discovers a new class like the SPECTRE etc. a few years ago.

      Even something as simple as the 6502 had errata, but at least the "bugs per transistor" metric has been falling as CPUs get more complex.

    Speculation

    I thought speculative execution was the work of the devil now? Or has Intel found some way of proofing all these cores against side channel data exfiltration?
