I don't understand on one of the later graphs the core to core latency for strix halo goes out to 32 cores but he says only has 16 cores?

I don't understand on one of the later graphs the core to core latency for strix halo goes out to 32 cores but he says only has 16 cores?
- wtallis 10mo agoAMD's cores have SMT, allowing them to run two threads at a time and appear to the OS and its scheduler as two logical cores despite being implemented as a single physical core.
- Neywiny 10mo agoWhat pattern in the data shows that's what's being measured? I would expect to see basically 0 latency between adjacent "cores" then since L1 is shared per thread?
- monocasa 10mo agoCo resident threads might not get any speed up here since coherency instructions are functionally operations on the L2 cache.
