The memory bandwidth on the Spark and Strix Halo is a fraction of the M5 Ultra. "Perform better" is probably a huge understatement.
When memory prices come back down, I'll be down to the Apple Store. But, it doesn't make sense to buy hardware right now.
I bought a refurbished M3 Max a couple of years ago just to try things out, I get 90 toks/s which is good enough for a lot of tasks. But ya, when DRAM prices come back down I'll definitely look for a better local rig.
