Technology

a toy for professional workloads

[rant]

I think this is one of those words which has lost its meaning in the personal computer world. What are people doing with computers these days? Every single technology reviewer is, well, a reviewer - a journalist. The heaviest workload that computer will ever see is Photoshop, and 98% of the time will be spent in word processing at 200 words per minute or on a web browser. A mid-level phone from 2016 can do pretty much all of that work without skipping a beat. That's "professional" work these days.

The heavy loads Macs are benchmarked to lift are usually video processing. Which, don't get me wrong, is compute intensive - but modern CPU designers have recognized that they can't lift that load in general purpose registers, so all modern chips have secondary pipelines which are essentially embedded ASICs optimized for very specific tasks. Video codecs are now, effectively, hardcoded onto the chips. Phone chips running at <3W TDP are encoding 8K60 in realtime and the cheapest i series Intel x64 chips are transcoding a dozen 4K60 streams while the main CPU is idle 80% of the time.

Yes, I get bent out of shape a bit over the "professional" workload claims because I work in an engineering field. I run finite elements models and, while sparce matrix solutions have gotten faster over the years, it's still a CPU intensive process and general (non video) matrix operations aren't really gaining all that much speed. Worse, I work in an industry with large, complex 2D files (PDFs with hundreds of 100MP images and overlain vector graphics) and the speed of rendering hasn't appreciably changed in several years because there's no pipeline optimization for it. People out there doing CFD and technical 3D modeling as well as other general compute-intensive tasks on what we used to call "workstations" are the professional applications which need real computational speed - and they're/we're just getting speed ratio improvements and the square root of the number of cores, when the software can even parallelize at all. All these manufacturers can miss me with the "professional" workloads of people surfing the web and doing word processing.

Yeah, I gave Apple a try over the last two years, largely because I was annoyed with Google and wanted to ditch Android. I've been fed up since about 6 months in, but gave it some more time, which led to an eventual waiting game to get the replacements I want.

I just picked up a Thinkpad P14s g4 AMD with a 7840u, 64GB of RAM, and a 3 year onsite warranty for $1270 after taxes. I added a 4TB Samsung 990 Pro for another $270. I can't imagine spending more than that and only getting 8GB RAM (and less warranty), which is what I have assigned to the GPU. Plus I get to run Linux, which I really didn't realize how much MacOS would leave me wanting.

The thing I'll miss is the iPhone 13 Mini size. I found iOS to be absolute trash, but there's just not an Android phone that's a reasonable size. But at least I can run Calyx/Graphene on a Pixel and get a decent OS without spying.

I do like the M1 MBA form factor, too, but I'll grab the Thinkpad X13s successor for portability and get a better keyboard. I don't need top end performance out of that, I really just want battery life and passive cooling.

And don't even get me started on the overpriced mess that are the Airpods Max. I much prefer the Audeze Maxwell and Sennheiser Momentum 4 I replaced them with.

Also, one of these days AMD or Intel will bolt 8GB on their CPUs too, and then they'll squash M.

I can't remember who it is but somebody is already doing this. But it's primarily marketed as an AI training chip. So basically only Microsoft and Google are able to buy them, even if you had the money, there isn't any stock left.
