Lenovo ThinkStation P620 Tower vs. Dell Vostro 3888 Compact Desktop

The Lenovo ThinkStation P620 Tower and the Dell Vostro 3888 Compact Desktop were released in the same year, 2020. The Lenovo ThinkStation P620 Tower has a full-tower form factor that can accommodate a large motherboard, multiple graphics cards, extra storage, and better cooling solution. The Dell Vostro 3888 Compact 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.

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 Lenovo ThinkStation P620 Tower, you have options to configure it with a 280W AMD Zen+ (Picasso) 12-core AMD Ryzen Threadripper PRO 3945WX up to a 280W 64-core AMD Ryzen Threadripper PRO 3995WX with a boost speed up to 4.20 GHz.

While Dell Vostro 3888 Compact Desktop has configurations 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.

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 Lenovo ThinkStation P620 Tower has eight RAM slots that support up to 1TB of 3200MHz 8 channels DDR4 ECC memory. On the other hand, the Dell Vostro 3888 Compact Desktop has two RAM slots that you can upgrade up to 64GB 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 10 USB ports available on the Lenovo ThinkStation P620 Tower, two more than the Dell Vostro 3888 Compact Desktop that has only 8 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 Lenovo ThinkStation P620 Tower has eight USB Type-A ports and two USB Type-C ports. It has two ports that support USB 2.0 (480 Mbps) and eight ports that support USB 3.2 Gen 2 (10 Gbps).

For Dell Vostro 3888 Compact Desktop, it has eight USB ports that all of which are USB Type-A. The PC has four ports that support USB 2.0 (480 Mbps) and four ports that support USB 3.2 Gen 1 (5 Gbps).
