Month ago bought my first iMac (in April 2020 bought MBP 16, my first Mac ever).
iMac 5K 2020 i7-10700, 64Gb RAM (DIY), Radeon 5700 8Gb, 2Tb SSD (1 Tb MacOS / 1Tb Win10 Pro). My second machine is Dell OptiPlex 7770 27'' 4K, i7-9700, 16Gb RAM, GeForce 1050 4Gb, 512Gb SSD (SK hynix). Working as Microsoft Dynamics NAV developer. Recently started to notice, that disk intensive tasks takes a while more on iMac compared to Dell.
Created following specific test:
Step 1: Generates 10 million records as temporary table with 10 integer fields, all fields constitutes table's primary key.
Step 2: Flushes all 10 million records to SQL server.
There are the results:
As iMac has 1 generation newer CPU (RAM speed equal - 2666Mhz) and temporary tables are stored in RAM, so RAM and CPU speed only matters, iMac did it faster, but when it came to saving temporary table to the disk, iMac was clear looser. And looser overall.
So in real life random file read/write speed matter more than those rarely used sequential speeds.
