The Dell Optiplex 3090 SFF has a small form factor that commonly can only fit a Mini ITX motherboard, one or two hard disk drives, and supports only a small form factor or half-height 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 Lenovo Legion Tower 7i 34IAZ7, you have options to configure it with a 125W 12th Generation Intel Alder Lake 10-core Intel Core i5-12600K up to a 125W 16-core Intel Core i9-12900KF with a boost speed up to 5.20 GHz.

While Dell Optiplex 3090 SFF has configurations with a 58W 10th Generation Intel Comet Lake dual-core Intel Celeron G5900 up to a 65W 6-core Intel Core i5-10600 with a boost speed up to 4.80 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.

Fortunately, both PC allows you to upgrade later if you are unsatisfied with the amount of memory on your PC. The Lenovo Legion Tower 7i 34IAZ7 has four RAM slots that support up to 128GB of 4800MHz dual-channel DDR5 memory. On the other hand, the Dell Optiplex 3090 SFF has two RAM slots that you can upgrade up to 64GB of 2666MHz 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 12 USB ports available on the Lenovo Legion Tower 7i 34IAZ7, four more than the Dell Optiplex 3090 SFF that has only 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.

The Lenovo Legion Tower 7i 34IAZ7 has eleven USB Type-A ports and one USB Type-C port. It has four ports that support USB 2.0 (480 Mbps), six ports that support USB 3.2 Gen 1 (5 Gbps), one port that supports USB 3.2 Gen 2 (10 Gbps), and one port that supports USB 3.2 Gen 2x2 (20 Gbps).

For Dell Optiplex 3090 SFF, it has eight USB ports that all of which are USB Type-A. The PC has four ports that support USB 2.0 (480 Mbps) and four ports that support USB 3.2 Gen 1 (5 Gbps).
