MOORE'S LAW is dead. So says no less an authority on the subject than Nvidia CEO and leather jacket aficionado Jensen Huang (pictured below). Actually, Huang has been composing Moore's Law's obituary since at least 2017, when he expressed doubts over its long-term viability at the GPU Technology Conference in Beijing. Then at CES in 2019, Hunag unambiguously decreed "Moore's Law isn't possible anymore." It was last year during a Q&A to promote the then-hot new RTX 4090 GPU that Huang figuratively unloaded the final cap, simply saying "Moore's Law is dead." But here's the thing. If you plot the transistor count of cutting-edge chips right up to the present day, it doesn't seem like there's been any slowdown in technological progress. But surely Huang knows what he is talking about? Actually, Huang isn't wrong. And yet transistor density in the latest chips is still increasing. You only have to glance at that logarithmic graph plotting transistor count progress since the 1970s to see that perfect straight line extends right up to today. So what, exactly, is going on?
LET’S BEGIN with a tale of transistor counts. Specifically, in the 1970s, when transistor counts topped out at about 10,000 in a single chip. By the end of the 1980s, that count had exploded to about one million in the Intel 486 CPU. The late 1990s saw that increase to 50 million in the Pentium 4. The 2000s delivered 2.5 billion in an eight-core Nehalemclass Intel server CPU. And that RTX 4090 that Huang launched in 2022? The AD102 chip it uses packs about 75 billion of the tiny switches. And so the logarithmic increase in transistor density continues to this day.

AMD's turn to drop the ball?
WITH INTEL'S RAPTOR LAKE CPUs falling over, the company firing around 15,000 employees, and cancelling its 2024 innovation event, AMD must have been enjoying the view - until its new Ryzen 9000 desktop CPUs rolled out. So, is AMD's CPU a minor stumble or game-changing fumble?
Intel issues fix for Raptor Lake degradation
EARLIER THIS YEAR, I wrote about difficulties I was having with a Core 19-13900K processor (see MPC230 Tech Talk). Little did we realize that we were only seeing the tip of the iceberg. While most complaints have involved the unlocked Core i9 Raptor Lake CPUs, it appears the instability problems build up and potentially impact many Raptor Lake-13th and 14th Gen Core CPUs, with Intel identifying 22 different desktop parts.
