The new 27 Inch I-Mac will have more processing and graphics power, it has the same SDXC card slot, and can be upgraded to 10Gig Ethernet, and you can upgrade the Ram yourself, (which you can't do on the I-Mac Pro). It has True Tone, the T2 Chip and all SSD up to 8 GB (the I-Mac Pro only goes to 4TB). Also the new I-Mac has the awesome Nano-texture Glass, and an Radeon Pro 5700XT with 16GB of GDDR6 graphics memory. Apple ought to call this one the I-Mac Pro and the smaller one the I-Mac.
