You can get a $600 Epyc with 128MB of cache. That shouldn't be too much compared to the tier of router we're talking about, right?

That's L3 cache though; they only have 0.5 MB of L2 cache per core.

I'm not really sure how much each of these types of memory cost, but I did find [1] which says "The cost of TCAM is also about 30 times more per bit of storage than SRAM". That suggests a CPU with something more like 0.5-1 GB of L3 cache would be a closer comparison.
