Unity is slow on any machine. With that said, there is a huge M1 hype on HN. It reminds me of the 64-bit ARM hype when someone benchmaked encryption (because ARMv8 has AES instructions) and everyone were made to belive that the new iPhone would be 3-4 times faster.

> With that said, there is a huge M1 hype on HN. The main thing driving this is that people are comparing a new M1 to their Intel Mac laptops with processors from ~2016 and then naturally it's a marked improvement because it's being compared to a five year old machine. You compare them to a modern Intel or AMD system and they're competitive. They win some and lose others. Much was made about the M1 Max taking the sin…

But don't compare to the modern desktops, only laptops. I often see that people want to compare new M1 to the latest desktops (hot and power-greedy), then say "well, just a little bit better in that benchmark" and think that it was a good and fair comparison :)

Mine just arrived today and I'm blown away. After upgrading our app's dependency chain to run native arm64 builds (which took a bit of googling) webpack's incremental build time on our app is down to 116ms from 983ms on my 2016 Macbook Pro. Over 8x faster. Our Tensorflow.js (webgl) models that previously ran about 8fps in the browser are now running at the camera's native 30fps framerate. (Similar to my desktop 2080t…

Are there any changes to be done in webpack itself to make the build process be quicker on a M1 machine?

Got mine last week and not only is it faster, the power usage is crazy good. I took it to town for the first time yesterday, thought I'd do some coding between meetings for a few hours. Battery is still over 90%. I actually don't know what the thing sounds like with fans on, because it hasn't happened yet. My old machine from 2019 would have been down to half power at least, and the fans used to come on with just two…

I’ve wondered for a while if the fans coming on due to dual monitors is a software / driver issue that could be fixed by a patch. It would save me from buying a new machine right now.

I believe these are actually one of the lowest markups Apple has and in general a great deal. Consider this: 1. 14” or 16” custom miniLED display 2. Anodized one-piece aluminum clamshell 3. Completely custom SoC (much more expensive than buying Intel’s latest, at least in the short-term) 4. Completely custom OS with a full suite of native apps 5. Custom MagSafe adapter 6. Thunderbolt 4 (3 of them) Now consider that t…

They must be getting their bread by charging $400 for the ram upgrade instead of the traditional $200 apple price for what should be $80 of memory.

Instead of complaining that RAM updates are so expensive, we could frame it as "Apple takes a lower margin on entry level configurations so they can offer the same quality hardware to price concious consumers".

Rather than switching hardware, you can also switch out the software to more efficient one. esbuild would make your builds go sub-ms even without needing a M1 CPU, also worth a try if you cannot switch to the newest hardware, so I guess this comment is for poor people.

Wouldn’t you need to change your entire build processes if you followed this route? I don’t do a lot of this type of dev but my understanding is esbuild wouldn't handle polyfill, for example.

I have an M1 Max. If anyone wants me to benchmark any workflows, I'd be glad to help!

Do you have two 4k displays? If yes, then does running them affects performance significantly? On i9 MBP this was causing extremely severe performance issues, to the point where processor was throttled to 30% performance.

I run two 5Ks and my 2019 Intel feels quite sluggish. I still pay that price for the real estate.

It’s because as soon as you plug in an external monitor, the dedicated GPU is used for the output and is responsible for the added heat

Interesting idea about the power usage of the interconnect. I don't remember this being discussed as an issue in tech press writings about multisocket Xeon or EPYC systems. Do you happen to have any references?

https://images.anandtech.com/doci/13124/IF%20Power%20EPYC.pn... Here's EPYC 7601's "IF" power (it's really all the uncore power) vs. the core power. Going outside the chip means swinging lots of capacitance up and down, and modern interconnects swing that capacitance fast .

And that's only for a 2p setup. An 8p setup would need even more interconnects per CPU depending on the architecture (eg, ring, mesh, etc..), which would have further impacts to performance depending on which tradeoffs are made.

Looking at pure performance without power usage is meaningless for these machines.

Power usage doesn’t scale linearly, at all. Mobile Ryzens are very competitive with the M1 watt for watt (trading blows with Ryzen winning sometimes). Seems you’ve fallen for Apple marketing again.

Ryzen is at a process disadvantage currently so Apple should be more efficient on average. When AMD gets on N5 (soon), it's going to be even more competitive.

> You compare them to a modern Intel or AMD system I compared my 2014 MBP to 2019 MBP and there was no marked difference. It was running hot and eating battery very fast. 2019 Intel Mac and 2020 M1 Mac are two completely different animals. Also, the price drop for a better-performing machine was jaw-dropping.

Apple selling you mid-range-3-year-old-intel CPUs (that are known to thermal throttle quite badly) at 50% markup, then robbing you slightly less hard on a product is not jaw dropping, it's merely you falling for their marketing three times in a row.

I'm not sure where you're getting that from...

The i9-9980HK (released April 2019) in the 16" 2019 Macbook Pro looks like the highest-end mobile i9 Intel had released as of November 2019 when the laptop launched.

And the i7-9750H in the base model was also launched in April of that year, and looks like it was their 2nd-fastest mobile hexacore i7 at the time?
