Doing stuff on two different windows just became a bit clumsier every time e.g. code reviews. I can imagine manually resizing windows when in a tiling mode.

We used to remove the hard drives which takes about 20 seconds on a desktop that has a "tool-less" case. Then donate the computer to anybody including the employees if they want it. It takes a few minutes to do that on a laptop but it's not that long.
Seems like FDE would solve that and make it a hardware non-issue.
Work if you trust FDE. Some FDE are broken, like this: https://www.zdnet.com/article/flaws-in-self-encrypting-ssds-...

this is mostly wrong. The real issue has always been memory bandwidth. the highest end consumer x86 CPU has about the same memory bandwidth as a dGPU from 10 years ago. The M1 is extremely competitive with modern dGPUs, only a bit behind a 6900 XT.
> this is mostly wrong. The real issue has always been memory bandwidth. Not really wrong. Memory bandwidth is only a limitation for a very narrow subset of problems. I've gone back and forth between server-grade AMD hardware with 4-channel and 8-channel DDR4 and consumer-grade hardware with 2-channel DDR4. For most of my work (compiling, mostly) the extra memory bandwidth didn't make any difference. The consumer par…
GP is talking specifically about GPUs. iGPUs are 100% bottlenecked by memory bandwidth; specifically it is the biggeset bottleneck for every single purchasable iGPU on the market (excluding M1 Pro/Max).
Your compute anecdotes have no bearing on (i)GPU bottlenecks.

#754"Apple’s Commitment to the Environment" > Today, Apple is carbon neutral for global corporate operations, and by 2030, plans to have net-zero climate impact across the entire business, which includes manufacturing supply chains and all product life cycles. This also means that every chip Apple creates, from design to manufacturing, will be 100 percent carbon neutral. But what they won't do is put the chip in an expan…
> what they wont do is put the chip in an expandable and repairable system Because that degrades the performance overall. SoC has proven itself to simply be more performant than a fully hotswappable architecture. Look at the GPU improvements they're mentioning - PCIe 5.0 (yet unreleased) maxes out at 128GB/s, whereas the SoC Apple has announced today is transferring between the CPU/GPU at 400GB/s. In the end, perform…
Comparing memory interface vs PCIe isn't valid. Comparing LPDDR5 vs DDR5 latency, throughput, and power consumption would be good.

#755I always thought it was strange that "integrated graphics" was, for years, was synonymous with "cheap, underperforming" compared to the power of a discrete GPU. I never could see any fundamental reason why "integrated" should mean "underpowered." Apple is turning things around, and is touting the benefits of high-performance integrated graphics.
Still confused how 32 core M1 Max competes with Nvidia's thousands-of-cores GPUs. Certainly there are some things that are nearly linear with core count, or otherwise they wouldn't keep adding cores, right? Edit: Found answer here. GPU core is not the same thing as a CUDA core. https://www.reddit.com/r/hardware/comments/73i3ne/why_do_app...
CPU core == Cuda SM

The desktop RTX 3070 has 46 SMs, which are the most comparable thing to Apple's cores.
NVIDIA defines any SIMD lane to be a core. They recently have gotten more creative with definition, they were able to double FP32 executions per unit (versus previous gen) and hence in marketing materials, doubled the number of "CUDA cores".

The software side hasn't been there on x86 GP platforms, even though AMD tried. It's worked out better on consoles.
What software is missing? I figured the AMD G-series CPUs used the same graphics drivers and same codepaths in those drivers for the same (Vega) architecture. My impression was that it was still the hardware holding things back: Everything but the latest desktop CPUs still using the older Vega architecture. And even those latest desktop CPUs are essentially PS5 chips that got binned out.
iGPU Vega is actually really, really good esp when it comes to perf/watt. It is bottlenecked by the slow memory bandwidth. DDR5 will more or less double iGPU performance.

Yes, it depends on what you're doing, but if you can watch 21 hours of video, many people will be able to do more than 24 hours of development.
Video playback is accelerated by essentially custom ASIC processing built into the CPU, so it's one of the most efficient things you can do now. Most development workloads are far more compute intensive.
Might be less computationally expensive. But video playback constantly refreshes screen which uses up battery

They are using LPDDR5. Not the usual DDR5 used in Desktop / Laptop.
DDR5 isn't common yet. DDR4 is the common desktop/laptop chip. LPDDR5 is cell-phone chip, so its kinda funny to see a low-power RAM being used in a very wide fashion like this.
Don't cell phones sell more than desktops, laptops, and servers? Smartphones aren't a toy: they are the highest volume computing device.
They are also innovating with things like on-chip ECC for LPDDR4+, while desktop DDR4 still doesn't have ECC thanks to Intel intentionally gimping it for market segmentation.

Honestly a MacOS "Pro Mode" would be great. Let me run the apps I want, not use my mouse, and be able to break things, but keep the non-power user experience smooth and easy.
Seconding this. If both iOS and MacOS had a "Pro Mode" that didn't treat me like a toddler, I'd be jumping into the Apple ecosystem head-first.
Thirded.
