    No mention of Moore's Law...

    > The number of transistors is way up, by about 50%, from roughly 11 billion to 16 billion. Most of the extra transistors went into the core, not the cache.

    From <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Moore%27s_law" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Moore%27s_law

    &gt; Moore&#x27;s law is the observation that the number of transistors in an integrated circuit (IC) doubles about every two years, with minimal increase in cost.

      Moore&#x27;s law is mostly dead these days. Process scaling still happens, but nowhere near at the rate predicted, and there are tradeoffs everywhere now. The Zen 5 core is in fact bigger in terms of die size too.

        Is it? Without Googling to backup my intuition, I thought that Moore&#x27;s Law is still alive, but people just get Moore&#x27;s Law wrong. A lot of people think it states that PERFORMANCE doubles, but it&#x27;s number of transistors.

        And while in the past, the doubling of transistors DID double performance, it&#x27;s no longer true.
