ok, then you say it is because consume a lot of energy decoding 4k trough software
Mi Box TV that works with 2,5V electricity, I guess has an apple T2 on it
I didn't say exactly that as I don't know properly the insides of these chips and all, but on these benchmarks they also put GPU and CPU usage counters. While editing, importing, exporting, etc and the hardware chips are being used, the CPU/GPU counter levels are on almost idle or very brief low peaks... which I think is nice? having the rest of the power for everything else.
That example sounded like "my alarm clock emits sounds so it must have a boombox inside it", not quite related in my opinion.
Regarding your box being 2,5V electricity... Voltage alone doesn't make or break something being efficient, outlets can output several amperes at a time, so if your box is 2.5V but sucking in 5A that's 12.5 Watts (I'm assuming direct current as it is an electronics device). 5A is a lot of current going through. An hypothetical 12V computer that uses 1A is still 12Watts.
EDIT: yes, remembering the original commenter and my comment forwarding, it does mention that battery performance is enhanced. Most probably because the rest of the system can stay on idle, i.e. low watts power draw.
Nah, it just has an efficient hardware decoder, that isn't exclusive to the Apple T2 chip.
Exactly, probably, or maybe it's software based but incredibly optimized for only very few of those tasks too. Who knows.
Also the Apple T2 chip happens to encode/decode efficiently, but it's mostly a security chip, SSD file access, encryption, decryption, audio handling, image signal processing, etc so that the rest of the system doesn't get taxed by those things. All of those things which I react as: "awesome, it came with it"
