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 Precision 3650 Tower Workstation, you have options to configure it with a 65W 10th Generation Intel Comet Lake quad-core Intel Core i3-10100 up to a 125W 8-core Intel Xeon W-1390P with a boost speed up to 5.30 GHz.

While Dell Optiplex 5090 Tower has configurations with a 58W 10th Generation Intel Comet Lake dual-core Intel Pentium Gold G6405 up to a 65W 8-core Intel Core i7-11700 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 four RAM slots meaning that you upgrade later if you are unsatisfied with the amount of memory on your PC. You can upgrade memory on Dell Precision 3650 Tower Workstation up to 64GB of 3200MHz or 128GB of 2933MHz ECC or non-ECC dual-channel DDR4 memory.

Ports
