I would really love to see some kind of PoC of running fully in cash a program. Having 104mb of you can run some performance critical stuff entirely from cash.

- kissiel 2y agoMost binaries you encounter today fit in this cache. This is what makes AMD's x3d chips so fast in games. And you're off by 8x on the size, it's 104MB.
- jpc0 2y agoSince were being pedantic. Is that 2^10 bits or 10^3 bits per MB?
- kevincox 2y agoIf we are being padantic 1 MB is 10^6 bytes. 1 MiB would be 2^20
- jpc0 2y agoI thought of that soon after my comment but I felt my point was made even better because of the bad maths
- kissiel 2y agoAMD writes MB, and they list the faster caches' sizes in KByte, where indeed I think it should be Mi and Ki respectively. And in the NV space (hdds, ssds) a GB means 10^9. Reminds me of DDR vendors telling us that memory runs at 8GHz (8GT/s, 4GHz in reality).
- rowanG077 2y agoBinary is not interesting. Data it operates on is.

- rowanG077 2y agoDram cache is not comparable to sram cache.
