Dell Vostro 3681 Small Desktop vs. Dell Optiplex 7090 SFF
The Dell Optiplex 7090 SFF is a newer system that was released in 2021, while the Dell Vostro 3681 Small Desktop was released years earlier in 2020. The Dell Vostro 3681 Small Desktop has a 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. The Dell Optiplex 7090 SFF has a small form factor that commonly can only fit a Mini ITX motherboard, one or two hard disk drives, and supports only a small form factor or half-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 Vostro 3681 Small Desktop, you have options to configure it with a 58W 10th Generation Intel Comet Lake dual-core Intel Celeron G5900 up to a 65W 8-core Intel Core i7-10700F with a boost speed up to 4.80 GHz.
While Dell Optiplex 7090 SFF has configurations with a 65W 10th Generation Intel Comet Lake quad-core Intel Core i3-10105 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.
Fortunately, both PC allows you to upgrade later if you are unsatisfied with the amount of memory on your PC. The Dell Vostro 3681 Small Desktop has two RAM slots that support up to 64GB of 2933MHz dual-channel DDR4 memory. On the other hand, the Dell Optiplex 7090 SFF has four RAM slots that you can upgrade up to 64GB of 3200MHz or 128GB of 2933MHz 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 8 USB ports available on the Dell Vostro 3681 Small Desktop, two less than the Dell Optiplex 7090 SFF that has 10 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 Vostro 3681 Small Desktop has eight USB ports USB ports that all of them are Type-A port. It has four ports that support USB 2.0 (480 Mbps) and four ports that support USB 3.2 Gen 1 (5 Gbps).
For Dell Optiplex 7090 SFF, 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), three ports that support USB 3.2 Gen 1 (5 Gbps), two ports that support USB 3.2 Gen 2 (10 Gbps), and one port that supports USB 3.2 Gen 2x2 (20 Gbps).
