Is there a tradeoff in terms of power consumption?

In A15, Anandtech claims the Efficiency cores are 1/3 the performance, but 1/10 the power. They should be looking at (effectively) doubling the power consumption over M1 with just the CPUs and assuming they don't increase clockspeeds.

Going from 8 to 16 or 32 GPU cores is another massive power increase.

Just today I got one 6s and one iPhone 7 screen repaired(6s got the glass replaced, the 7 got full assembly replaced) and battery of the 6s replaced at a shop that is not authorized by Apple. It cost me 110$ in total. Previously I got 2017 Macbook Air SSD upgraded using an SSD and an adapter that I ordered from Amazon. What’s that narrative that Apple devices are not upgradable or repairable? It simply not true. If a…

True, but you are talking about devices that are 4-6 years old. Storage is now soldered. Ram has been soldered for a while now, and with Apple Silicon its part of the SoC.

For context, Apple started soldering RAM in 2015 and soldering storage in 2018.

How do they get 200/400GB per second RAM bandwidth? Isn't that like 4/8 channel DDR5. 4/8 times as fast as current Intel/AMD CPUs/APUs? (E.g. https://www.intel.com/content/www/us/en/products/sku/201837/... with 45.8GB/s) Laptop/desktop have 2 channels. High-end desktop can have 4 channels. Servers have 8 channels. How does Apple do that? I was always assuming that having that many channels is prohibitive in terms of…

That sound like HBM2, maybe HBM3 but that would be the first consumer product to include it afaik.

Basically the bus is really large, and the memory dies must be really close to the main processing die. Those memory were notably on the RX Vega from AMD, and before that on the R9 Fury.

The benchmark to power consumption comparisons were very interesting. It seemed very un-Apple to be making such direct comparisons to competitors, especially when the Razer Blade Advanced had slightly better performance with far higher power consumption. I feel like typically Apple just says "Fastest we've ever made, it's so thin, so many nits, you'll love it" and leaves it at that. I'll be very curious to see those…

> I'll be very curious to see those comparisons picked apart when people get their hands on these, and I think it's time for me to give Macbooks another chance after switching exclusively to linux for the past couple years. I really enjoy linux as a development environment, but this is going to be VERY difficult to compete with..

You can always run Linux in a VM too

Hardware people are crafty, they find ways to transfer and combine working parts. The glass replacement(keeping the original LCD) I got for the 6S is not a procedure provided by Apple. Guess who doesn’t care? The repair shop that bought a machine from China for separating and re-assembly of the Glass and LCD. Screen replacement is 50$, glass replacement is 30$. iPhone 13 is very new, give it a few years and the hardw…

And how will the crafty HW people replace the SSD storage on my 2020 Macbok if it bites the dust?

By changing chips. There are already procedures for fun stuff like upgrading the RAM on the non-retina MacBook Airs to 16GB. Apple never offered 16GB version off that laptop but you can have it[0].

if there’s a demand there would be a response.

Yes. But the 14" and 16" has larger battery than 13" MacBook Pro or Air. And they were designed for performance, so two less EE core doesn't matter as much.

It is also important to note, despite the name with M1, we dont know if the CPU core are the same as the one used in M1 / A14. Or did they used A15 design where the energy efficient core had significant improvement. Since the Video Decoder used in M1 Pro and Max seems to be from A15, the LPDDR5 is also a new memory controller.

This only makes sense if you presume people throw away their laptops when they replace them after "a few years". Given the incredibly high second hand value of macbooks, I think most people sell them or hand them down.

You're talking about selling working devices but parent was also talking about repairing them. Seems like a huge waste to throw away a $2000+ machine when it's out of warranty because some $5 part on it dies and Apple not only doesn't provide a spare but actively fights anyone trying to repare them, while the options they realistically will give you out of warranty being having your motherboard replaced for some insa…

> Or what if you're a klutz and spill your grape juice glass over your keyboard? Congrats, now you're -$2000 lighter since there's no way to take it apart and clean the sticky mess inside.

Thanks to the Right To Repair, you can take the laptop to pretty much any repair shop and they can replace anything you damaged with OEM or third-party parts. They even have schematics, so they can just desolder and resolder failed chips. In the past, this sort of thing would be a logic board swap for $1000 at the very least, but now it's just $30 + labor.

Oh, there is no right to repair. So I guess give Apple $2000 again and don't drink liquids at work.

In the power/performance curves provided by Apple, they imply that the Pro/Max provides the same level of performance at a slightly lower power consumption than the original M1.

But at the same time, Apple isn't providing any hard data or explaining their methodology. I dunno how much we should be reading into the graphs. /shrug
