What are people's experience of developing with NVIDIA? I know what Linus thinks: https://www.youtube.com/watch?v=iYWzMvlj2RQ

Linus might know his way around UNIX clones and SCM systems, however he doesn't do graphics.

NVidia tooling is the best among all GPU vendors.

CUDA has been polyglot since version 3.0, you get proper IDE and GPGPU debugging tools, and a plethora of libraries for most uses cases one could think of using a GPGPU for.

OpenCL did not fail only because of NVidia not caring, Intel and AMD have hardly done anything with it that could compete on the same tooling level.

That time was years and years ago. If you're just thinking about it now, you're already in a world of pain.

Intel stock is up 37% from 5 years ago. Though this past year they took quite a beating.

This is really not that much considering how much every stock has gone up the last couple of years. Nvidia and AMD is up 887% and 737% respectively from 5 years ago.

I think we're all missing the forest because all the cores are in the way: The contention on that memory means that only segregated non-cooporative as in not "joint parallel on the same memory atomic" will scale on this hardware better than on a 4-core vanilla Xeon from 2018 per watt. So you might aswell buy 20 Jetson Nanos and connect them over the network. Let that sink in... NOTHING is improving at all... there is…

1030 has been dethroned a while ago. Apple G13 delivers 260GFLOPS/W in a general-purpose GPU. I mean, their phone has more GPU FLOPS than a 1030.

Though, there is a shortage of m1 MacBooks. Is it really because they are low value (margin?) products relative to iPhone? I'm not sure.

I was pretty surprised by the low prices of m1 macbooks when even the lowest end models perform so much better than the high end of previous models. I'm sure Apple is spending less money on manufacturing them now that they're not going through Intel, but I would have expected them to just keep charging the same and eaten the profit margin themselves.

They are trying to establish the new architecture. Also you still need to shell out $2-3k to get something decent and practically start at $1.5k. I wouldn't call that cheap or even cheaper. What is the past difference you see?

They're all using the exact same CPU, in fact you can make the air perform (almost) just as well as the pro/mini by opening it up and adding a thermal pad: https://www.cultofmac.com/759693/thermal-mod-m1-macbook-air/

Starting price for the air is $999, which gets you a very fast computer (albeit one a bit anemic in memory). A couple of years ago, the starting price for the air was still $999, but you got a... much less fast computer.

Nvidia's been making their own CPUs for a long time now. IIRC the first tegra was used in the Zune HD back in 2009. Hell they've even tried their hand at their own cpu core designs too. https://www.anandtech.com/show/7621/nvidia-reveals-first-det... https://www.anandtech.com/show/7622/nvidia-tegra-k1/2

Maybe even more importantly: Tegra powers the Nintendo Switch.

Note the CPU cores in that design aren't designed by NVidia.

Not much of a shortage. I just checked and they are all available for pickup right now at my local small city store. Compared to other products they are still extremely available.

Interesting, I see nothing available from store.apple.com until 6 April earliest, and 29 April for m1 max and even later depending on options.

Interesting that this has 7x the cores of a M1 Ultra, but only 25% more memory bandwidth. Those will be some thirsty cores!

The CPU complex on the M1 series doesn't have anything close to the full bandwidth to memory that the SoC has (like, half). The only thing that can drive the full bandwidth is the GPU.
