Dell Optiplex 5090 Micro vs. Dell Optiplex 7090 Micro

The Dell Optiplex 5090 Micro and the Dell Optiplex 7090 Micro were released in the same year, 2021. Both systems share the same micro form factor that can only fit a custom-designed motherboard with none or one expansion slot and supports only a specific OEM 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 Dell Optiplex 5090 Micro, you have options to configure it with a 35W 10th Generation Intel Comet Lake quad-core Intel Core i3-10105T up to a 35W 8-core Intel Core i7-11700T with a boost speed up to 4.60 GHz.

While Dell Optiplex 7090 Micro has configurations with a 35W 10th Generation Intel Comet Lake quad-core Intel Core i3-10105T up to a 65W 8-core Intel Core i9-11900 with a boost speed up to 5.20 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 3200MHz 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 6 USB ports available on both PCs. 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 Dell Optiplex 5090 Micro has five USB Type-A ports and one USB Type-C port. It has five ports that support USB 3.2 Gen 1 (5 Gbps) and one port that supports USB 3.2 Gen 2 (10 Gbps).

For Dell Optiplex 7090 Micro, it has five USB Type-A ports and one USB Type-C port. The PC has two ports that support USB 3.2 Gen 1 (5 Gbps), three ports that support USB 3.2 Gen 2 (10 Gbps), and one port that supports USB 3.2 Gen 2x2 (20 Gbps).
