Why do these new machines have 192 cores, not a power of 2? (3* 2^6) = 192. The article mentions 256 and 512 cores coming. I get that various components can limit scaling like say bus speed or capacity. But 192, that's wacky. |

> Architectural design: The physical layout of the chip may favor certain core arrangements. For example, a 48-core processor could be designed as a 6x8 grid, which efficiently utilizes the square shape of the silicon die6.[1]
Major Deep Thought vibes.
