Thanks! That just above covers it I think!It depends on whether Apple skips A-series core generations with each M-series generation. More recent A-series chips see about a 10-15% boost in CPU speed per generation, but with larger boosts in graphics. If we go with the assumption that each M-series generation matches the A series generation-for-generation then an M2 Mac would have a single core Geekbench score of about 1800-ish and an M3 would potentially be pushing 2100. But if Apple decides to do an 18-24 month refresh cycle on M processors and only use even numbered A series chips then the M2 would be closer to 1900-2000 single core and the M3 could hit 2500, but the catch would be the M3 might not materialize until 2024 or later with the A18.
The biggest performance boost will be going from Intel to M-series just by virtue of Apple’s optimizations and sheer efficiency gains, with lesser gains coming from each successive M-series generation (just like where the iPhone is at now). Going from an M1 to an M3 will certainly give a performance boost but the M1 is already faster than most average consumers need half the time.
what? we are already talking about 3nm for M3...and you are talking about regressing to 4nm for M4?Impressive. I just hope they can keep it up and have the 4nm process ready in time for M4
You are correct, and the industry is working on it. Intel went with the later, switching from nanometers to Angstroms. 1 A = 0.1 nm. Intel is shooting for 2024 for release of 20A branded chips which would be 2 nm.It seems each year this is reduced by 1. Once they do hit 1nm what happens next. I know its not zero, it must become a decimal of the size or is there a smaller unit of measure to switch to. Must be option two now that I type it out.
And seeing as the M1s can handle 8k video without breaking stride, what will the practical advantages of the M3 variants be?
I don't expect iPad Pro to use M2, but rather a 3nm M2X.
iPad Pro already has a higher base price than MacBook Air and I doubt Apple will continue using a high wattage design in their most expensive tablets.
Makes 0 sense. A "M2x" would be an M2 with more cores so thats a nogo for the power limits of a tablet.
A smaller "M2" would just be A15(x) or A16(x) which also doesn't make sense.
-> iPP will get the base M2 (assuming it has a similar power draw to the M1) which will be overkill for iPadOS and people will pay the price to the same features the M1 iPP has over an M1 MBA.
Probably picometer, else move away from silicon entirely.It seems each year this is reduced by 1. Once they do hit 1nm what happens next. I know its not zero, it must become a decimal of the size or is there a smaller unit of measure to switch to. Must be option two now that I type it out.
Next generation may be quantum computing...It seems each year this is reduced by 1. Once they do hit 1nm what happens next. I know its not zero, it must become a decimal of the size or is there a smaller unit of measure to switch to. Must be option two now that I type it out.
M2 in 2022 and M3 in 2023, I don't get how that's too fast?Sounds weird to me, M1 is being dragged to 2 years with M1 Pro and M1 Max release recently hsving atleast 1 year of shelf life. How come within 1 year they will release M2 and then go on for M3 by end of same year. I think it will make sense to have m2 in September/October as usual followed by M2 Pro and M2 Max
My first Mac (Centris 650) used a 650nm (0.65µm) process. We sure have come a long way.I recall the days when 32nm chips were awe inspiring
That is pure fantasy.IBM produced the planet's first-ever 2nm chip in early May.
Intel is a Tech Partner of IBM.
I suspect the two will be offering 2nm manufacturing to third-parties by mid-2022.
Would NOT be at all surprised if Apple is already talking to them about trying it out with a Test Chip.
Ideally, that Test Chip would be a 12 Mpx 2um 10-bit image sensor with super-low ADC read noise !
Tim, are you seeing this ?
I jumped from a 14nm Skylake m3 MacBook to a M1 Pro MacBook Pro and the improvements were massive. Before I was constantly hitting the limits of the CPU, now I have far more power than I'll ever need. I haven't heard the fans spin yet after several months of ownership and the battery life is great.By the time I get around to replacing my 2013 22nm Haswell iMac the improvements are going to be OFF the charts.
Only if they put a gigantic Apple on it as the primary visual…Cue BMW suing Apple: “too fast, can create brand confusion”.
