Here are the results for a Dell OptiPlex 3040 in a small form factor (SFF) configuration.

The machine was manufactured in 2017 which I recently bought in 2022 from a local seller on Ebay for around $80 CAD (without a hard drive). The i3-6100 processor seems to be on par with the older benchmark I did on the Dell OptiPlex 3010 which had an i3-3220 CPU back in 2013 (wow, that was 9 years ago!).

PCI devices[edit | edit source]

This computer is really basic. I was a bit disappointed to see it comes with an integrated Realtek gigabit adapter, considering that everything else is Intel based. Other disappointments include there being only 2 SATA ports on board the OptiPlex 3040 and no onboard WiFi/Bluetooth.
