I've now owned two 2018 Mac mini computers. 1) Returned: Custom order that I returned to Apple after realizing spending over $1800 on a Mac mini wasn't for me. $1599 for Mac mini from Apple - 3.2GHz i7 6-core with hyperthreading and turbo up to 4.6GHz - 512GB storage (the storage is so fast) - 10 GBE (because why not - I might eventually need it) $269 for 32GB of Corsair RAM that I installed. Sale prices are cheaper, but I just returned this. I only need 16GB. 2) Recently purchased via Black Friday Sales: $699 Entry level i3 ($799 from Apple, $699 from Adorama with AppleInsider code) - 3.6GHz i3 4-core - 128GB storage (boot drive and apps only) $109 for 16GB of G.Skill RAM that I installed. $169 for Samsung T5 1TB external (for my Lightroom library). I saved about $900 and I'm not sure I will really notice much of a difference for the work I do (Lightroom Perpetual 6.14). The i3 definitely runs cooler when pushed. I can't get it to hit Tjunction=100 degC. I feel like I really got wrapped up in wanting to have "the best" whereas, for me, the entry level i3 will be just fine. --- Post Merged, Nov 28, 2018 --- Screenshot of trying to get the i3 to throttle/hit Tjunction=100 degC. 1) yes command running to keep the CPU pegged. 2) Cinebench OpenGL running to keep the Intel 630 GPU generating heat. Note: I can't get above ~48 watts total power and 93 deg C temperature. While the i3-8100B and i7-8700B are both "TDP=65W", they aren't really equivalent thermally. --- Post Merged, Nov 28, 2018 --- Attached are two more screenshots of trying to build up heat with consecutive Cinebench CPU runs. First screenshot is first two runs from an idle temp of ~40 deg C. Second screenshot is after 5 runs. Notice the i3-8100B CPU alone will only peg out ~38 watts of power and I can't get the Mac mini to break 90 deg C with just the CPU taxed. The slight dips from 3.6 GHz are just the Cinebench run finishing before I can launch another run.
