Why Apple's move to an ARM Mac is going to be a bumpy road for some
Actually AMD is in the loop as far as 5nm goes! Even with the 7nm node AMD is eating the hell out of Intel.tht said:
The rumored Apple custom CPU for Mac is going to be fabbed on TSMC 5 nm. That's a 70% higher transistor density than the transistor densities afforded by Intel 10 nm or TSMC 7 nm, which AMD uses. And, Intel may still be fabbing desktop processors on 14 nm in the fall. That really boggles the mind and Apple at minimum should be jumping to AMD or their own custom processor ASAP.jdb8167 said:This has been done before with the Intel transition. The Rosetta emulator for going from PowerPC to Intel x86 was quite effective. The problem with the ARM transition is that the ARM CPU isn’t likely to be as much faster from the Intel CPU as was the Intel CPU from the PowerPC CPU. So any slowdowns will seem like very poor performance.
TSMC 5 nm has a 3x to 4x density advantage over Intel 14 nm. Like with AMD with TSMC 7 nm Zen 2 is crushing Intel 14 nm processors in perf/watt/$, Apple is going to crush AMD and Intel if they are fabbing these processors TSMC 5 nm while AMD is on 7 nm and Intel is using whatever they are using by then.The only real problem with 5nm is heat which will require more care in SoC design. Otherwise 5nm is looking to be HUGE. ( couldn’t resist). I’m fact if AMD gets there next year they will likely bury Intel, if Intel can’t get on anew node.In any event for Apple 5nm will mean a massive performance bump of a huge power savings. Likely they will split what 5nm offers down the middle to reduce power and increase performance. This would mean an A14 that could reach mid to high end laptop performance. That means better cooling than an iPhone but still amazing.Im really excited about what A14 will be! They could use all of that die space for far more functionality or instead shop a very small chip for phones. It is just fascinating to think about the direction Apple will take.

2020 iPad Pro's A12Z shows little improvement over 2018's A12X in early benchmarks
This is a rather disgusting turn at Apple. They have literally taken cue from the video card makers and given us a new model with nothing of real value added. Sad!I can’t ever being so negative with respect to Apple. It seems like at every turn they have become a milking machine for old tech. Little innovation and lots of lipstick for old pigs.

New iMac and Mac mini coming soon, says leaker
Bad experiences with Apples laptops and the lack of real updates to the Mini forced me to buy outside their ecosystem a few years ago. I’ve seen nothing yet to convince me that they have focused on function, reliability and usability in new machines. Hopefully we will see signs of Apple addressing these issues in IMac and Mini.charlesatlas said:hentaiboy said:Apple’s “forgotten child” getting a refresh already?
Yeah, it went four years without a refresh last time, and now it's getting one after just 18 months? I don't buy it.

I’m hoping to evidence that Apple is taking the entire Mac line up seriously. In some cases that means radical changes in design before I will buy.hentaiboy said:Apple’s “forgotten child” getting a refresh already?In the context of the Mini I’d love to see an AMD chip in the box. More importantly we need an open SSD slot. Also toolless entry into the box should be a reality. Basically we need an acknowledgement from Apple that not all of the potential Mac users are idiots.IMac is a different ball game with well known issues. I will not be considering one so it doesn’t matter much to me. However moving from Intel’s power hungry chips to AMD would be good here too. -
Why Apple will move Macs to ARM, and what consumers get
I really don’t know where this BS comes from but ARM multitasks just like any other systems processor. In fact with non equal cores it has advantages that even Intel is copying. The only limits put on ARM are implementation based.mham4908 said:The technology for ARM to do the extensive multi-tasking that Intel chips provide does not exist today. Arm chips can only now do very small multi-tasking operations. The technology for ARM is still several years away. The main advantage for Apple is Temperature, always on, non comparability with the open architecture that Intel has, (IE Kill Hackintosh) and MORE PROFIT. The most important for them being the last two. Because we know even with the bargain basement chip that ARM is Apple will not drop their pricing. I am old enough to remember when Mac had a completely closed architecture and sales was probably 1% of what it is today. Moving to Intel allowed them to grow to where they are today. ARM will be the death of Mac. Not Apply but the Mac for sure.A common mistake is that people look at the A series and think that Apple's desktop and laptops will look just like it. At first there may be lots of similarities but in the end we will see very different processors fall out of the development process. For one caches will be careful bigger, there will be PCI Express or other high speed buss support and most likely vastly more powerful AI acceleration hardware.One needs to think about how Apple will build a laptop processor not so much about how they will put an A series in the Mac. Sure the cores will move over but from that point on it will be a very different chip.
