Re: Apple Silicon in Macs

I'm not sure how much Apple would benefit from switching over to ARM from x86. Considering that going over to x86 from PPC gave Macs a huge boost sales increasing marketshare of Apple. Benefits will depend on whether price/performance/watt improvements materialize and (perhaps more importantly) if ...

Re: TBDR APU for desktop

TBDR APU for desktop

https://9to5mac.com/2020/07/08/arm-mac-graphics/ The track record for apples marketing regarding Mac gaming is abysmal, so spread the salt thick. HOWEVER.... this sounds really interesting. I’ve been skeptical of the APU concept, but maybe AMD just hasn’t had the resources to implement it well. If a...

https://wccftech.com/apple-custom-mac-cpu-cost-node/ It's not clear that there's really any credible sourcing here, but a couple of interesting bits: 1. sounds like the first Macs might use the (5nm) A14X which would presumably also be use din the iPad Pro.

Re: Apple Silicon in Macs

Interesting perspective:

https://www.pcgamer.com/intel-skylake-why-apple-left/

I'm sure that bugs in skylake isn't the only reason -- maybe more a "straw that broke the camel's back" kind of thing.

But this is a piece of the puzzle that I was not aware of.

Re: Apple Silicon in Macs

Yeah that's true. I've heard video editing on the ipad actually works pretty well assuming you're using a codec that's supported in hardware. Obviously the hardware has to be good before choice of codec can make a difference. I'm not sure how much of a priority macOS really is for Apple in general,...

Intel ought to be getting back on their feet by the time Apple finishes their transition. But will they? By 2022, intel will finally have 7nm desktop CPUs (assuming they meet targets). Intel’s 7nm is approx TSMC 5nm, which comes out this year. Apple might have moved on to TSMC 3nm by 2022. Compared...

Does the 8 big + 8 little config imply the end of hyper threading? I doubt it - hyperthreading adds real performance in addition to saving power with aggressive power saving profiles.
