Hey, a multi-threaded quad core is better than the current Mac mini offering...?
I would rather this portion of the post I linked...
But a decent modern medium power multi-core/multi-threaded CPU (8th gen i5s & i7s) & the ability to have an eGPU (hello, Vega 56 Nano) would be a good route to go as well...
Which allows the option of RX5XX-series GPUs or Vega GPUs in the eGPU box...
But if Apple were to go with Intel CPU/iGPU & TB3 for eGPU, I would love to see Apple-branded expansion box that fits under the new Mac mini & houses either RX5XX-series or Vega series GPUs, in the MXM format...
With a trick TB3 interconnect between the modules so no wires out back...
