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 2021 Lenovo IdeaCentre Gaming 5i, you have options to configure it with a 65W 10th Generation Intel Comet Lake 6-core Intel Core i5-10400 up to a 65W 8-core Intel Core i7-11700F with a boost speed up to 4.90 GHz.

While Dell Inspiron 3891 Desktop has configurations 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.

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.

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 7 USB ports available on the 2021 Lenovo IdeaCentre Gaming 5i, one less than the Dell Inspiron 3891 Desktop that has 8 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.
