It’s not a hard limit, especially if you aren’t pushing the frequency wall like Intel. AMD used to use a 2-way 64kb L1, Intel has an 8-way 64kb L1i on Gracemont

It’s not a hard limit, especially if you aren’t pushing the frequency wall like Intel. AMD used to use a 2-way 64kb L1, Intel has an 8-way 64kb L1i on Gracemont, and more to the point, high-end ARM Cortex has had 4-way 64kb L1 caches since before they even supported 16kb pages.
- aseipp 7mo agoYeah, I was more just trying to paint a broad picture. Nvidia in particular I think had fast and large-ish L1 on Tegra (X2?) despite being tied to 4k pages.
