• Our computers represent tiny tiny numbers in a form called 'subnormal'. They have a reputation for causing performance problems... but my results indicate that on recent processor architectures, they may only cause a problem for Intel.

• Global AI stocks fell today. Entirely consistent with my view that calls for AI safety are not an attempt at "regulatory capture" and entirely inconsistent with the supposedly cynic-sophisticated view that AI fears are all 4D chess moves for higher revenue. On stocks falling. Here is Claude: The public tape moved hard this morning. Global AI stocks fell on Monday, with SoftBank down sharply along with chip stocks from SK Hynix to ASML, Micron and Intel. SoftBank closed nearly 11% lower in Japan, the Kospi sank 3.3% on a 6.4% drop in SK Hynix, and ASML was off 6% in Europe. In the US, Marvell,…

• Apple design its own chips for its phones. The latest CPU is the A20 Pro. Geekbench is a benchmark with a database of results; you can run your own benchmarks and share your numbers with the world. In the last few days, we finally got some A20 Pro results and the numbers are impressive... reaching 4000 in single-core (one thread) performance. For comparison, the best that you can do with an x64 AMD or Intel processor is something like the Ryzen 9 9950X3D2 at about 3,163 which would be somewhere between the A18 and A19. The A20 Pro is 25% faster on this benchmark than any AMD or Intel processo…

• To show how much I care about performance, I just ordered the worst specced 2020 Intel MacBook Air I could find (i3, 1.1 GHz, 8 GB RAM). It is the last supported hardware for macOS 15, our min target for Superlogical. Going to optimize on it for worst-case behavior.

• Is there a service where I can rent access to Linux desktop machines with actual displays? We're implementing the Playbit runtime for Linux and it's surprisingly difficult to test various desktop configurations. We need a real GPU with a display connected, for testing dawn/webgpu, vsync, display sleep, etc. We use Modal and AWS, neither have had machines that I've been able to test with properly. Ideally there's a way to test a variety of systems (like ubuntu, arch, alpine etc) × GPUs (nvidia, amd, intel) × window managers.

• I was thinking about this prediction that we were going to see a lot more CPU bugs, danluu.com/cpu-bugs/, as yet another Intel CPU bug story is on the front page of HN. At the time, Intel threw quality under the bus in the name of velocity. I've seen this happen quite a few times now, sometimes with the stated intention of improving quality later. I'm sure it's ever happened, but I don't think I've ever seen a company do this and then ship very high quality products later.
