Some technical decisions aren’t that important. A trivial example, I have very strong preference on using tabs instead of spaces for indentation. However, I don’t force people on my team to also use tabs because I realize that’s subjective,

I agree with GP. The reason is simple, business model. Google’s main source of income, by far, is selling ads. Not just any ads but highly targeted ones, which means global digital surveillance is an essential part of their business model.

The specialized accelerators discussed in the article have much slower memory than a 5090 GPU. The memory in them delivers 448 or 512 GB/s, only around 2x compared to Strix Halo.

If I were an enthusiast, I would rather consider a mini PC with AMD Strix Halo APU. These things have been coming soon for a few months now. The memory is slower but not by much, 256 GB/s is much faster than system memory found in most

It’s unfortunate they have deprecated it. We how have DXVK which implements D3D11, including compute shaders, for any platform which supports Vulkan. Making that (or a conceptually similar) thing work across platforms is no longer prohibiti

I don’t know answer to your question, but I recalled something relevant. Some time ago, Microsoft had a tech which compiled almost normal looking C++ into Direct3D 11 compute shaders: https://learn.microsoft.com/en-us/c

Good point. I forgot that in addition to DXVK they also have WineD3D.

I don’t think the support depends on distros much, I think the main variable is hardware. If you have a desktop PC bought in the last ~5 years the support should be OK, for the hardware older than that the support is not guaranteed. GeForce

Personally, I would avoid it if possible. Even if they are of the same model, small discrepancies may cause their +12V to be slightly different. At the very least, will cause very non-uniform load distribution. Luckily, seems the OP only ne
