Moore's law isn't carrying the weight it used to :(
Also squeezing ever more single threaded performance from inherently parallel scaling only (more transistors running at the same speed), as well as memory not being able to scale at the same rate as computing performance is really putting a damper on things.
- mmaniac 2y agoMoore's law only talks about transistors - in an IC they should double every 2 years. 3 years after the Apple M1, the M3 increased transistor count from 16 billion to 25 billion. Two years saw the 5950x with 8.3 billion transistors go to the 7950x with 13.1 billion transistors. That's quite not the predicted rate of scaling, but it is respectable. 2x the transistors doesn't mean 2x the performance though. We can make plenty of logic, but the DRAM to feed it remains high latency and the SRAM to hide the latency isn't scaling well either. PHYs are consuming proportionally more silicon too. One might say that Moore's Law isn't dead, but diminishing in relevance.
