Dell Optiplex 3280 All-in-One vs. Dell Inspiron 24 5400 All-in-One

The Dell Optiplex 3280 All-in-One and the Dell Inspiron 24 5400 All-in-One were released in the same year, 2020. Both systems share the same all-in-one form factor that combines all components and a built-in monitor into one package.

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 3280 All-in-One, you have options to configure it with a 35W 10th Generation Intel Comet Lake dual-core Intel Celeron G5900T up to a 35W 6-core Intel Core i5-10600T with a boost speed up to 4.00 GHz.

While Dell Inspiron 24 5400 All-in-One 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 i7-1165G7 with a boost speed up to 4.70 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 Dell Optiplex 3280 All-in-One up to 64GB of 2666MHz dual-channel DDR4 memory. For Dell Inspiron 24 5400 All-in-One, it supports up to 32GB 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 6 USB ports available on the Dell Optiplex 3280 All-in-One, one more than the Dell Inspiron 24 5400 All-in-One that has only 5 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 Dell Optiplex 3280 All-in-One has five USB Type-A ports and one USB Type-C port. It has two ports that support USB 2.0 (480 Mbps) and four ports that support USB 3.2 Gen 1 (5 Gbps).

For Dell Inspiron 24 5400 All-in-One, it has four USB Type-A ports and one USB Type-C port. The PC has one port that supports USB 2.0 (480 Mbps), three ports that support USB 3.2 Gen 1 (5 Gbps), and one port that supports USB 3.2 Gen 2 (10 Gbps).
