Hey,

it would be awesome to get even bigger Co-Processors.

I would love the steps from crafting/storage cells.

Something like:
1 -> 4 -> 16 -> 64 -> 256 -> etc.

Why? It would save alot of space and we already have MASSIV crafting cpu's.

I hesitate to go any higher than 4 without a compellingly expensive recipe to boot

My idea for such a recipe would have one 16-core crafting co-processor unit cost four 4-core co-processor units, some netherite, and Accumulation Processors.

The "four 4x co-processor units" cost means this is a way to compact CPUs even further by recycling 4-core units into more compact 16-core units (since many large bases utilizing MEGA Cells will have large crafting CPUs with many 4-core co-processors), while the netherite and Accumulation Processors are meant to push the tech level for that compaction a bit further.

The API that allows for the 4x co-processor only goes as high as 16 co-processor threads per block. I hesitate to go any higher than 4 without a compellingly expensive recipe to boot.

Mhmm, I saw it in GregTech New Horizons, but it probably was a heavily modified version of AE.

Indeed, GTNH maintains its own fork of AE2 for 1.7.10.

oh yeah i would definitely enjoy having a 16-core processing unit (maybe call it the Quantum Co-Processing Unit?) Even if we can't go above 16 in one block, that would still be a huge boost to efficiency.

as for making it suitably expensive, maybe something involving singularities would suffice? It would fit thematically (hence the name quantum) and singularities are kinda annoying to make.
