How did AMD Ryzen get 50% faster in two years?
People still tell me that CPUs are boring. That nothing much happens anymore. Let us look at AMD Ryzen 7 processors from 2022 to 2024: the 5800X3D (Zen 3), the 7800X3D (Zen 4) and the 9800X3D (Zen 5). They are comparable 8-core chips with 3D V-Cache. I have written about them before, in How stagnant … Continue reading…

Recreating Voodoo Graphics and a Late-1990s Gaming PC on an FPGA
I've spent the last month adding features and improving performance in z486_MiSTer , mostly working through games from the first half of the 1990s. Looking a few years ahead brought me to another change I wanted to explore: the arrival of 3D graphics cards.

Retrospectively Reverse-Engineering Apple's Neural Engine
I stopped working on the reverse-engineered Apple Neural Engine (ANE) driver three years ago, upon a sad mini realization that the ANE block is just not that useful, and I could be doing more useful things, and moved onto upstreaming other, more useful, blocks. The ANE's architecture was too opinionated to build a…
