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 Optiplex 3090 SFF, you have options to configure it 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.

While Dell Optiplex 7090 Ultra has configurations with a 28W 11th Generation Intel Tiger Lake UP3 dual-core Intel Core i3-1115G4 up to a 28W quad-core Intel Core i7-1185G7 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.
