Apple M1 CPU in the heat - awesome!!
Discussion
Just an FYI for those that might find it interesting.
As the UK heatwave is going on and breaking 100 degrees F (38C). It makes for a potentially hot working environment if you have no aircon. Colleagues with Windows & Macs are reporting issues with the machines not running well. And indeed my works Macbook Pro (Intel) has gone very very sluggish.
It has maxed it fans out and everything seems very hot, although a work colleagues Mac is running even hotter than mine is. By contrast I have a personal Mac Mini with the Apple M1 CPU in. It is barely warm by comparison, they fan is on its lowest setting and it is running fine. Ironically the Mac mini is physically located in a much worse place too, sandwiched between the wall and a 4k monitor (that is on) sat in a VESA cradle.
Shows really how far ahead of the game the M1 chip is when put to this kind of use.

38C is a lot for the UK, but nothing worldwide. These machines are built to run in places
as different as Hawaii to Maine, Alaska to Texas.
If you'd have said 50C, I'd have been mildly impressed.
Also, I don't know much about the M1 chip, but six core doesn't seem a lot.
Trailing edge tech in some parts.
I've been on 8 core for six years and about to retire it off and jump to 12 core.
16+ core machines are common enough (< £1000 I think).

and since when does the number of cores have direct correlation to performance?38C is a lot for the UK, but nothing worldwide. These machines are built to run in places

Crikey. Approximately 100% of the time !?
If you can demonstrate a machine for which adding cores reduced it's performance,
I'd be surprised.
Improved architecture has a much more important role in performance than simply the number of cores.
Just saying “hurr durr six cores is rubbish” suggests you know nothing about computers?

I read it as saying: "adding more cores to the same processor never makes it slower"!Improved architecture has a much more important role in performance than simply the number of cores.

My Dell XPS 13 with i7 has the fan on full all day in these temperatures, even when I don't do anything and it's just idling with Outlook, Excel etc. My Macbook Pro M1 Pro which has just arrived and I'm building up today hasn't made a sound yet, not sure if the fans are running or not.

cards and paper tape of the late 1970s - about 45 years. Not many posters on here alive then,
never mind programming.
Sure different architectures have different performances, but that wasn't the original (daft) statement.
Six cores isn't really all that impressive these days. Ok Apple will have you paying an arm
and a leg for their currently fashionable M1, but over in AMD land, six core CPUs
are about £100 or so. Small change.

As for the temps. Most countries with 38c outside have aircon. I’m willing to bet my laptop wasn’t the only one running slow today

They also require 10 times more power.My 5800X / RTX3080Ti combo was £3k, and does keep up when using full power.
These are cross-platform Geekbench 5 scores:
- 2022 Mac Studio "M1 Max" 10 CPU/32 GPU - 1757 (single) & 12420 (multi)
- 2020 AMD 5800x / RTX3080Ti - 1680 (single) & 10426 (multi)
I work on the Mac, but I game on the Windows PC

At the other end of the scale, this afternoon I had an I5-2500k CPU maxing at 80 degrees and the Nvidia GTX970 GPU maxing the hotspot temp at 97 degrees. Nvidia say the max is 98 degrees.
To be fair, I was running Overwatch at 2480 x 1440 when the ambient temp in the room was 33 degrees... the PC casing was rather warm.

I think you need to go back to your punch tape it’s clear you don’t know what you are talking about !robsa said:
The M1/M2 Pro/Max etc. are not just a CPU, they are an SoC that combines RAM, CPU and GPU along with other custom silicon. They are specifically designed and built to work with Apple's own hardware and ARM OS and software and are absolutely cutting-edge.
This month. Life moves on, and I am sure Apple will be selling something else horribly overpriced in a few months time.

There aren't, as far as I am aware, any other similar commercial chips that get even close to them; there is currently nothing to touch them in terms of performance versus efficiency.
Of course. They are based on ARM chips, which do well at performance per watt.But if you are merely looking for performance, you won't find it with anything ARM based.
You might find it with AMD or Intel, the latter if you want to pay more money.
The Apple kit seems to keep happy the video mob: pretty pictures, great video performance,
schocking prices, not much else.
Real horsepower, for example the server or workstation market, is elsewhere.
