Dell Optiplex 7080 Tower vs. Dell Optiplex 7070 Tower
The Dell Optiplex 7080 Tower is a newer system that was released in 2020, while the Dell Optiplex 7070 Tower was released a year earlier in 2019. Both systems share the same mini tower form factor that can fit a micro ATX and Mini ITX motherboard, a few hard disk drives, and a single full-height 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 7080 Tower, you have options to configure it with a 65W 10th Generation Intel Comet Lake quad-core Intel Core i3-10100 up to a 125W 10-core Intel Core i9-10900K with a boost speed up to 5.30 GHz.
While Dell Optiplex 7070 Tower has configurations with a 65W 9th Generation Intel Coffee Lake quad-core Intel Core i3-9100 up to a 65W 8-core Intel Core i9-9900 with a boost speed up to 5.00 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 Optiplex 7080 Tower up to 128GB of 2933MHz dual-channel DDR4 memory. For Dell Optiplex 7070 Tower, it supports up to 64GB 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 10 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 7080 Tower has nine USB Type-A ports and one USB Type-C port. It has four ports that support USB 2.0 (480 Mbps), three ports that support USB 3.2 Gen 1 (5 Gbps), and three ports that support USB 3.2 Gen 2 (10 Gbps).
For Dell Optiplex 7070 Tower, it has nine USB Type-A ports and one USB Type-C port. The PC has four ports that support USB 2.0 (480 Mbps), five ports that support USB 3.2 Gen 1 (5 Gbps), and one port that supports USB 3.2 Gen 2 (10 Gbps).
