MoltenVK exists and runs Vulkan on Apple devices perfectly fine. Almost certainly better than WebGPU does even. Vulkan is already a common API both in theory and in practice. It's not a nice API, but it is common and vendor neutral a

The fact that the address space starts at 0x0 comboned with no ASLR seems like some pretty major regressions in security. Nearly all SIGSEGV crashes just became memory corruption bugs, for example. That's huge . And of course WASM won

What does Mozilla use Spidermonkey instead of V8? Why did Apple create B3 JIT instead of just using Turbofan? Competing implementations are a cornerstone of standards. Indeed in many domains it's a requirement for a spec to have multip

Vulkan & GLES are both the obvious competition here, I don't know why you seem to be ignoring them?

Except unlike WebAssembly this one is actually useful. WASM enters a domain full of existing universal bytecodes that all failed to become truly universal because the actual assembly is never the hard part to get portable, it's the API

Rust is a genuinely interesting language but I think part of the problem is that a lot of the posts about it lately are just not. There's been a string of "we did generic boring thing everyone has been doing for a decade+ BUT IN R

And Android and QT and GTK and Chrome and Firefox and etc... The article is talking about the same generic hybrid GPU-accelerated rendering architecture that everything uses. Seemingly the only "new" part is "in Rust!"

You don't need to redraw the entire framebuffer with GPU rendering, either. It's perfectly possible to do small, partial updates. See for example https://registry.khronos.org/EGL/extensions/EXT/EGL_E

Math it out then. How much resistance is that few centimeters of PCB trace costing & what does that translate to in terms of milliwatts? Resistance is proportional to length, yes, but that doesn't make it significant in the given a

Which the M1/M2 is doing as well... It's just soldered RAM, not on-die RAM. Completely off-the-shelf LPDDR modules that are shipping in dozens of other laptops. Absolutely nothing special about the RAM at all.

The ARM servers use just as much power as the x86 ones and are typically slower as well. Same for the workstations. Apple makes a great ARM CPU core but nobody else does, and Apple ain't sharing.

Other ARM SoC vendors do, absolutely, which is a big factor in why most other ARM SoCs are so far behind Apple's. But Intel & AMD less so, they tend to prioritize just outright performance since that's how they're nearly

You have that like exactly backwards. You'll get a lot fewer bios updates from Dell or Lenovo than you will from MSI, Asus, Gigabyte, etc.. consumer / gaming motherboard lines. My 5 year old X370-F GAMING is still getting BIOS up

That doesn't pass a sniff test at all. The 7950X3D TDP is 120W vs. the 7950X's 170W, even ignoring that modern TDP is a dumb metric actual power consumption also backs that up - the 7950X3D uses signiifcantly less power than a 795

Perhaps but I have no idea how any scheduler can possibly figure out if a workload is frequency or cache sensitive. The current strategy seems to be "if game, use cache, else use frequency" and it sorta works OK-ish? Although then

Or buy an X3D that's homogeneous, like the 5800X3D or upcoming 7800X3D. I have no idea why AMD made the 7950X3D be this weird 50/50 split. Why not make both CCDs have 3D V-cache and make it the true halo part it should be? Then cu

I don't use the gsl, no, but I do use linters (like clang-tidy) that enforce a decent chunk of the guide. And reference like a style guide (or any documentation really), yes.

C++ has the same basic thing but in a better way with `if constexpr`. There you're opting in to lazy evaluation and can scrutinize it better without having all your branches everywhere be lazy evaluation such that wrong code is allowed
