There's a lot more to the perf improvement tapering than changes in Moore's law (which is about circuit complexity increasing at given cost), namely problems translating the increasing transistor budget to ipc improvement or failing that, solving parallel programming. And clock speed improvements.
- dahart 6y agoFWIW, I don’t think perf improvements are slowing down, I just think efficiency improvements in ICs are. Flops per watt of general compute isn’t moving quickly, and can’t anymore. But we can still make bigger parallel machines, design better algorithms, solve new problems, etc.
- fulafel 6y agoOutside HPC/ML I think our programs are now trading off useful ops per watt to take some advantage of the elusive beast called thread level parallelism. A web browser is happy to get a speedup of N by throwing 2N or 4N spinning threads at the problem if correctness and stability can be retained.
