Is Cuckoo really a good idea? about grin HOT 4 CLOSED

Well the article mentions a few times how Tromp was able to show how Equihash wasn't as good as originally thought:

However, as of writing Tromp has managed to get memory requirements down to just 144MiB! The Equihash paper predicted that kind of optimization would incur a multiple orders of magnitude penalty… not a good sign.

For example, Tromp has reported good equihash performance on NVIDIA GTX980 GPU, which as of writing has a retail cost of about $500 USD and comes with 4GiB of GDDR5 DRAM; if Equihash really works as intended, the cost of that RAM should dominate hashing costs.

And Tromp is the guy who created Cuckoo so I'm assuming he is improving on Equihash's shortcomings.

Yes, I know. I was mostly referring to specialized memory chips/High Bandwidth Memory (HBM).

Cuckoo is limited by memory latency vs equihash which is limited by memory bandwidth.

@apoelstra thanks for explanation!
