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 Optiplex 3090 Micro has configurations with a 35W 10th Generation Intel Comet Lake dual-core Intel Celeron G5905T 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 2021 Lenovo IdeaCentre Gaming 5i up to 32GB of 3200MHz dual-channel DDR4 memory. For Dell Optiplex 3090 Micro, it supports up to 64GB 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 7 USB ports available on the 2021 Lenovo IdeaCentre Gaming 5i, two more than the Dell Optiplex 3090 Micro that has only 5 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 2021 Lenovo IdeaCentre Gaming 5i has six USB Type-A ports and one USB Type-C port. It has four ports that support USB 2.0 (480 Mbps), two ports that support USB 3.2 Gen 1 (5 Gbps), and one port that supports USB 3.2 Gen 2 (10 Gbps).
