Dell Optiplex 7070 SFF vs. Lenovo IdeaCentre A540 AIO (27”, Intel)

The Lenovo IdeaCentre A540 AIO (27”, Intel) has an 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 7070 SFF, you have options to configure it 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.

While Lenovo IdeaCentre A540 AIO (27”, Intel) has configurations with a 35W 9th Generation Intel Coffee Lake quad-core Intel Core i3-9100T up to a 35W 8-core Intel Core i7-9700T with a boost speed up to 4.30 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.

Fortunately, both PC allows you to upgrade later if you are unsatisfied with the amount of memory on your PC. The Dell Optiplex 7070 SFF has four RAM slots that support up to 64GB of 2666MHz dual-channel DDR4 memory. On the other hand, the Lenovo IdeaCentre A540 AIO (27”, Intel) has two RAM slots that you can upgrade up to 16GB 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 the Dell Optiplex 7070 SFF, five more than the Lenovo IdeaCentre A540 AIO (27”, Intel) 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 7070 SFF has nine USB Type-A ports and one USB Type-C port. It 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).

For Lenovo IdeaCentre A540 AIO (27”, Intel), it has four USB Type-A ports and one USB Type-C port. The PC has two ports that support USB 2.0 (480 Mbps), one port that supports USB 3.2 Gen 1 (5 Gbps), and two ports that support USB 3.2 Gen 2 (10 Gbps).
