The integrated GPU in your processor is not an additional bit of computing power your computer is not using, but special software that can use your processor to put out graphics if a dedicated GPU is missing. It is extremely inferior at processing graphics compared to the real dedicated GPU, and if you were running firefox to watch (Not decode) youtube, you would very likely see things like screen tearing as the processor struggled to keep up.
This is straight up wrong. You are confusing GPUs with display adapters.
iGPUs are an actual on-die GPU, consiting of their own hardware, present on the die in addition to the CPU.
They can game. They can hardware decode and encode media, etc. They are full GPUs. Some are even quite powerful, though usually you’ll find them to be designed for everyday use and only light gaming.
The GPU in every recent game console is technically an iGPU, same goes for phones, and the Steamdeck.
They do not “translate” GPU instructions into running on the CPU cores.
That’s software rendering, and is what CPUs do when there isn’t an iGPU at all. (Though they’ll still need a display adapter, which a GPU can act as. But a display adapter doesn’t need to be a full on GPU. And iGPUs aren’t just display adapters.)
He’s kinda grown up with his audience. I dropped out of watching as I hit adulthood, then tuned back in for his “meme review” phase, where the inside joke was that everyone watching was a nine-year-old, when in reality he already had an aging audience.
He eventually grew bored with the format (and at that point already he made it clear he was doing it for fun, not because he needed to). The view counts steadily trended downwards as he switched to making videos he wanted to make, instead of ones that made money, as he was set by then.
At some point he ran a book-club style format, because he wanted to get into reading more. At least some portion of the fanbase was into that, but at that point he lost a lot of viewership.
Nowadays he seems to post very infrequently, and it seems to mostly be vlog-style content about family life and living in Japan.
