so much to take apart here. Yes chips run at an operating temperature, no biggie there, just a terrible lack of understanding. Apple silicon produces far less heat for the same tasks than almost all intel chips, they may not run cooler, but there is way less heat to remove. All ne has to do to verify this is to look at the numerous benchmarks where they see how much wattage is used, more wattage = more heat. Depending what you are doing, the battery will be drained at a rate determined by the usage. My M! MBP literally can last all weekend for web browsing, email and other stuff. Not so on my Intel MBP. You literally will not notice speed difference for using the web and another non-constrained tasks. But literally all the benchmarks show a vast performance improvement for CPU and graphics intensive tasks, but the SSDs are pretty much the same, so some things you will not notice.
It would be nice instead of a rant, you would perform some actual benchmarks about what you are not noting any speed improvements on. also, the i9 is a pretty high end chip from intel, so like I said, not all taks will show an improvement
