Wow does much better than Geekbench's prior top processor ( https://browser.geekbench.com/processor-benchmarks ) the Intel Core i9-11900K ( https://browser.geekbench.com/processors/intel-core-i9-11900... ). 10,997 for Intel i9 vs 12,693 for M1 Max
What about this? https://browser.geekbench.com/v5/cpu/7421821

Over 6 years, 2x the performance in single-core and 4x (for 2.5x the cores, depending how you count) seems surprisingly low compared to stuff I've read (not experienced yet) with the M1.
I think a lot of the perceivable speedup in M1 Macs is less to do with these benchmarks and more to do with optimizing the OS and Apple software for the M1 and the various accelerators on the SoC (video encoding and ML).

What compiler could even make use of 10 cores? Most build processes I've run can't even fully utilize the 4 cores.
Just running the tests in our Rails project (11k of them) can stress out a ton; we're regularly running it on 80+ cores to keep our test completion time ~3 minutes. M1 Max should let me run all tests locally much faster than I can today.

16GB of RAM seems so low in 2021. OTOH, hard drives are so fast on these things that maybe 16 is good enough with the SSD as overflow. I ended up shelling out the extra $400 for 32GB, but didn't feel great about it!
I've heard from people with M1 laptops that they perform surprisingly better than Intel laptops with less RAM (on the Mac). I imagine the same will hold with the Pro and Max, although it will depend a lot on what type of work you're doing.

On the other hand I've been running 16GB of ram for a while and I can't conceive of a reason why I would need more. 32GB seems like overkill. What would you do with all of that ram? Open more tabs?
Compilation, graphics work, heavy-weight IDEs And, if you're spinning on 16GB ram on an M1, you might be eating through the SSD powering your swap space and not know it.

Does someone know how much VRAM the M1X has? Because I bet it's far less than a 3070 or 3080.
the memory is unified so whatever ram is on there (16,32,64) can be allocated as vram. That's why during the presentation they bragged about how certain demanding 3d scenes can now be rendered on a notebook.

It's probably bad, the M1 could not get 60fps on WoW so ... When I see Apple comparison I would take that with a grain of salts because the M1 is not able to run any modern game at decent fps.
Are modern games built with Metal? Pretty sure Apple deprecated OpenGL support. Macs have never been gaming computers. The GPUs in the M1 family of Macs are for “professional” users doing Video Editing, Content creation, 3D editing, Photo editing and audio processing.
But does it support running x86 Docker images using hardware emulation? This is what's holding me off buying one since I don't know whether to get 16 GB RAM (if it doesn't work) or 32 GB RAM (if it does work).
There is no hardware in the M1's for x86 emulation. Rosetta 2 does on the fly translation for JIT and caches translation for x86_864 binaries on first launch. Docker for Mac runs a VM, inside that VM (which is Linux for ARM) if you run an x86_64 docker image it will use qemu to emulate x86_64 and run Linux Intel ELF binaries as if they were ARM. That means that currently using Docker on macOS if there is a native ARM…

The memory is unified, and very high bandwidth. No idea what that means in practice, guess we'll find out.
It's very high bandwidth for a CPU, but not that great for a GPU (400GB/s vs 440GB/s in 3070 and 980GB/s in 3090).
* almost equals the highest laptop GPU available
I'm in the situation where I really want to pre-order a 14", but I have no idea if going with the base model would be a mistake. Would upgrading to 32GB RAM make Xcode faster? Or would it be a waste of $400?
Anecdotal example: I could have several Firefox tabs with active workers in the background (WhatsApp, Slack, etc.), a Zoom meeting with video conferencing on, with audio and video being routed via OBS (native), a Screen Sharing session over SSH going, and a Kubernetes cluster in Docker running, and that won't even make the MacBook hot. Nothing slows down. I could get maybe five hours out of the battery this way. Usually six.
Doing that on a maxed out Intel MacBook Pro will make it sound like a jet engine and reduce my battery life to two or three hours. It will also slow to a crawl.
I'm guessing buying a machine with 32GB of RAM is an investment into the future where workloads on m1 machines are high enough to actually give the memory a run for its money.
