Processor
The Central Processing Unit (CPU) is like the brains of your desktop computer. Its performance determines how fast and responsive your PC is.

For Lenovo ThinkCentre M90a, you have options to configure it with a 58W 10th Generation Intel Comet Lake dual-core Intel Celeron G5900 up to a 65W 10-core Intel Core i9-10900 with a boost speed up to 5.20 GHz.
While Dell Optiplex 3080 Micro has configurations with a 35W 10th Generation Intel Comet Lake dual-core Intel Celeron G5900T 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 both systems 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.
