Dell Inspiron 3891 Desktop vs. Lenovo IdeaCentre Mini 5i

The Dell Inspiron 3891 Desktop and the Lenovo IdeaCentre Mini 5i were released in the same year, 2021. The Dell Inspiron 3891 Desktop has a mini tower form factor that can fit a micro ATX and Mini ITX motherboard, a few hard disk drives, and a single full-height graphics card. The Lenovo IdeaCentre Mini 5i has a micro form factor that can only fit a custom-designed motherboard with none or one expansion slot and supports only a specific OEM graphics card.

Processor

The Central Processing Unit (CPU) is like the brains of your desktop computer. Its performance determines how fast and responsive your PC is. Generally, a processor with newer architecture, more CPU cores, higher TDP (measured in W), and faster clock speed (measured in GHz) tends to be more expensive and run faster than others with older architecture, fewer CPU cores, lower TDP, and lower clock speed.

For Dell Inspiron 3891 Desktop, you have options to configure it with a 58W 10th Generation Intel Comet Lake dual-core Intel Celeron G5905 up to a 65W 8-core Intel Core i7-11700F with a boost speed up to 4.90 GHz.

While Lenovo IdeaCentre Mini 5i has configurations with a 65W 10th Generation Intel Comet Lake quad-core Intel Core i3-10100 up to a 35W 8-core Intel Core i7-10700T with a boost speed up to 4.50 GHz.

Memory

The Random Access Memory or RAM is the super-fast and temporary storage used to handle all active tasks, apps, and games that will go away when your PC turns off. The more memory your PC has, the better multitasking your PC can handle without having to reload data from slower permanent storage that includes the hard disk drive or solid-state drive.

Both PCs have the same amount of two RAM slots meaning that you upgrade later if you are unsatisfied with the amount of memory on your PC. You can upgrade memory on Dell Inspiron 3891 Desktop up to 64GB of 2933MHz dual-channel DDR4 memory. For Lenovo IdeaCentre Mini 5i, it supports up to 32GB of 2933MHz dual-channel DDR4 memory.

Ports

Computer ports are the interface for connecting your PC to its peripheral devices or other PCs. The most common peripherals are keyboard, mouse, monitor, flash drive, speaker, and printer. Most of them use Universal Serial Bus (USB) as their connection to your computer. So the PC with more USB ports can connect to more peripherals at the same time.

There is a total number of 8 USB ports available on the Dell Inspiron 3891 Desktop, two more than the Lenovo IdeaCentre Mini 5i that has only 6 USB ports. On top of the number of USB ports, the type and version of each USB port are also necessary for determining how fast it is.

The Dell Inspiron 3891 Desktop has seven USB Type-A ports and one USB Type-C port. It has four ports that support USB 2.0 (480 Mbps) and four ports that support USB 3.2 Gen 1 (5 Gbps).

For Lenovo IdeaCentre Mini 5i, it has five USB Type-A ports and one USB Type-C port. All of them supports USB 3.2 Gen 1 (5 Gbps).
