I plan to get the M4 MBP. Currently on 16" M1 Pro 16GB/1TB config. I really loved the machine, it's quiet, but too big. My primary goal is to get a 14".
I have been 'guessing' the performance as well, based on the M3 family and the M4 iPad Pro. As an apple silicon user since M1 Pro, I have been able to do my casual games on the MBP. It's mostly through a simulation layer or similar, not native (Ryujinx, Whisky and Parallels). I have found it therefore ram and vram lacking and also the gpu. So I hope to go at least double that (36GB seems to be the next level) and 'better' gpu (M4 pro?) or more gpu (M4 Max, base or 'maxed' gpu model).
It seems that the M3 Max (30gpu or 40 gpu) battery usage is higher than the M1 Pro, so they last (slightly) shorter. Plus me going from a 16" to a 14" will reduces it even more. Therefore I also hope that the M4 will be more power efficient. I believe the non Max models would last last long or longer than the M1 Pro 16", but I would assume the Max models will still consume more power and last shorter. It seems that more performance just takes more power (so less efficient).
Then there is the issue of the difference between M1/2 Pro vs M3 Pro. Initially they had 200Gb/s, now they offer 150GB/s for the Pro. So M3 = 100GB/s, M3 Pro = 150GB/s, M3 Max base = 300GB/s, Max max = 400GB/s. Also the M3 Pro has more efficiency cores (in comparison to performance cores) in comparison with the M1 Pro. Somehow they have tweaked the M3 Pro to be 'more' in the middle between the M3 and M3 max models, whereas in the M1 family, the M1 Pro seems to be much more performant comparatively. Therefore for those M3 Pro buyers, who needs more than 16/18GB of ram slowly find themselves upselling to the 'base' M3 Max.
1) M1 Pro -> M4 Pro: I know CPU wise it won't be much of a difference, would you think it should now be time to upgrade as perhaps GPU will be a drastic upgrade (e.g. playing games will yield at least 20 more fps?)
2) M1 Pro -> M4 Pro vs M4 Max: Would M4 Max still be less in efficiency draining more battery even at idle/normal tasks? I know M1~M3 Max has been like that. I am hoping that with newer technology now M4 Max will still yield better battery life than M1 Pro.
Thanks.
Sorry to blabber on like that, it's just that I have been looking at too much info on these in the last month.
1) Yes I think the GPU has been much better arleady since the M1 Pro. If you look at benchmarks, the M3 Pro has been able to play so many games much better than the M1 Pro. So the M4 Pro would assumignly do so as well.
2) The M2/3 Pro last 1 hour longer than M1 Pro (according to Apple's compare Macs' site). I would imagine that the M4 max (base, the low GPU config, not high gpu config) would still last less than the M1 Pro (33.7 billion transistors) due to higher wattage usage of such a Max chip (was the M3 Max 97 billion transistors?). Eventually a smaller transistor count chip, I assume, would just use less power and therefore make the battery last longer.
However, it's more important to look at your own use case. If you never 'drain' the battery to less than 20% for instance, you might be ok with a Max model? And if you never maxed out the M1 Pro, any other upgrade will be much better already. Do you know your usage? I have been using the
istats menu for years now. The advantage is that it shows a 30 day history of the usage of my cpu, ram, battery, gpu and temps. So I can easily see when I have been 'maxing' out the machine or not. You can just do a trial for the coming week and see it yourself?
And in my case I definitely need more gpu and ram due to casual games that I have been playing. Based on YouTube research, it seems that a M1 Max gpu would come close to my gaming needs, so I compare those numbers to the latest M3 chips, and it seems to me that I still would need to go to a 'based' M3 Max (
https://browser.geekbench.com/mac-benchmarks/). Some games I watch was it baldurs gate or some other native title was hitting ~40 fps on M3 Pro, which I think would be nice to be more closer to 60 fps, so again a M3 Max would be better. Unless the M4 Pro would provide more than 18GPU cores, I think it wouldn't be enough a jump for me.
Anyways, that has been my research so far.
