Question Liquid nitrogen cooling for M4

[amosliu137]

Maybe it is the first time to use Liquid nitrogen cooling ARM chip? The M4 is so difficult to gain 4.42Ghz in room temperature . The guys in Geekerwan use Liquid nitrogen to get the best performance of geekbench. M4 get 3977 for Geekbench 6 and 2754 for Geekbench 5.

Isn't M4 a locked chip? Are they able to overclock M4? If not, then it's useless

Due to the lack of their reference run without extra cooling, this doesn't tell us a lot. We've had runs at more than 3800 since the first results, and the first runs at more than 3900 started to appear on May 12th. And last, there are runs that high currently in the DB. So unless they pushed their results, I fail to see what this demonstrates.

Also the picture for GB6 lacks frequency which I find suspicious (or is it always like that on the device?).

It was a contest on China social media, one guy put his ipad in frozen freezer to get 3934, Geekerwan decided to go with liquid nitrogen for better results

Thanks for clarifying, these contests can be fun

OTOH gaining 1% is not a lot.

I've found a video of him (I hope I'm correct he's the same person) with a score of 3843/14712 at 7:43. So all in all that'd be a gain of less than 2.5% for ST and 1% for MT.

Highest multi-core is 14924:

Benchmark results for an iPad16,4 with an ARM processor.

It's a different model, BTW. That's the freezer guy I believe.

I think the MBP would break 4,000 quite easily. But the iPad got close!

Thanks, I didn't know about it before.

Yeah, there was some confusion about that. So my chart is still correct, @Nothingness ?


3900 for M4 seems on-point, but I'll have to correct the clock speed to 4.4 GHz.

The source for my 4.5 GHz listing is Geekerwan:

How did he achieve 4.5 GHz?

For what it's worth, I ran Geekbench on my own M4 iPad Pro and got 3736 as the Geekbench 6 ST Score, so these scores seem legitimate with exotic cooling.

I pointed to some small issues when you first posted the spreadsheet. Like too high GB6 score for iPad (cf @Cardyak post above).
