> The DDR being closer to the core may or may not allow the memory to run at higher speeds due to better signal integrity, but you can purchase DDR4-5333 today whereas the M1 uses 4266. My understanding is that bringing the RAM closer increases the bandwidth (better latency and larger buses), not necessarily the speed of the RAM dies. Also, if I am not mistaken, the RAM in the new M1s is LP-DDR5 (I read that, but it…

The overall bandwidth isn't affected much by the distance alone. Latency, yes, in the sense that the signal literally has to travel further, but that difference is miniscule (like 1/10th of a nanosecond) compared to overall DDR access latencies. Better signal integrity could allow for larger busses, but I don't think this is actually a single 512 bit bus. I think it's multiple channels of smaller busses (32 or 64 bit…

DRAM latencies are pretty heinous. It makes me wonder if the memory industry will go through a similar transition to the storage industry's HDD->SSD sometime in the not too distant future.

I wonder about the practicalities of going to SRAM for main memory. I doubt silicon real estate would be the limiting factor (1T1C to 6T, isn't it?) and Apple charges a king's ransom for RAM anyway. Power might be a problem though. Does anyone have figures for SRAM power consumption on modern processes?

I am in the market for a new laptop and bit skeptic for M1 Chips. Could anyone please tell me how is this not a "premium high performance Chromebook" ?

Why should I buy this and not Dell XPS machine if I will be using it for web development/Android Development/C#/DevOps. Might soon mess with machine learning

My F500 company has a 5 year tech refresh policy, and old laptops are trashed, not donated or resold.

Exactly, corporate never risks them getting into wrong hands, no matter how theoretical risk that might be. Same for phones

We used to remove the hard drives which takes about 20 seconds on a desktop that has a "tool-less" case. Then donate the computer to anybody including the employees if they want it.

It takes a few minutes to do that on a laptop but it's not that long.

Apple almost single-handedly made computing devices non-repairable or upgradable; across their own product line and the industry in general due to their outsized influence.

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.

> 140W USB-C Power Adapter Wait huh? My current 16" Intel Core i9 is only 95watts. Does this mean all my existing USB-C power infrastructure won't work?

Maybe its a typo and they mean the Magsafe3 connector? I though the USB-C standard was limited to 100 watts.

Dell USB-C power adapters have exceeded 100 watts in the past on e.g. the XPS 17

Thats not how industry works, thats not how any of this works. iPhone ecosystem is big enough to move itself forward, but desktop market plays by different rules.If you don't follow what majority of the market do, it's much cheaper to just ignore that tiny customer segment which requires totally alien set of technologies

iOS and Macs both use Metal.

You can't refuse to support Metal without missing out on a very big slice of total gaming revenue.

I hate the naming. By name alone and without looking at specs, can you tell me which is the faster chip-- the M1 Max or the M1 Pro?

The M1 Pro is faster. The M1 MAX is an M1, but with new control software which makes it keep crashing.

wrong

I am a very satisfied Apple customer, but will gladly tell you that a Windows machine would make more sense for the use cases you’ve described.

Which is precisely what I said. They don't care that the larger gaming market ignores their platform. Apple Arcade and other gaming related endeavours all aim at the casual mobile gamer market.

I suspect the GPU is never really idle. Even simple screen refresh blending say 5 layers and outputting it to a 4k screen is 190Gbits at 144 Hz.

Don't Apple iPhones use an adaptive refresh rate nowadays?

Indeed ProMotion is coming to these new MacBooks too.
