Dell Precision 3650 Tower Workstation vs. Lenovo ThinkStation P350 Tower

The Dell Precision 3650 Tower Workstation and the Lenovo ThinkStation P350 Tower were released in the same year, 2021. The Dell Precision 3650 Tower Workstation 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 Lenovo ThinkStation P350 Tower has a full-tower form factor that can accommodate a large motherboard, multiple graphics cards, extra storage, and better cooling solution.

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 Precision 3650 Tower Workstation, you have options to configure it with a 65W 10th Generation Intel Comet Lake quad-core Intel Core i3-10100 up to a 125W 8-core Intel Xeon W-1390P with a boost speed up to 5.30 GHz.

While Lenovo ThinkStation P350 Tower has configurations with a 65W 10th Generation Intel Comet Lake quad-core Intel Core i3-10105 up to a 125W 8-core Intel Xeon W-1390P with a boost speed up to 5.30 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.

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 Precision 3650 Tower Workstation up to 64GB of 3200MHz or 128GB of 2933MHz ECC or non-ECC dual-channel DDR4 memory. For Lenovo ThinkStation P350 Tower, it supports up to 128GB of 3200MHz 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 9 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 Precision 3650 Tower Workstation has eight 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 two ports that support USB 3.2 Gen 2 (10 Gbps).

For Lenovo ThinkStation P350 Tower, it has eight USB Type-A ports and one USB Type-C port. The PC has six ports that support USB 3.2 Gen 1 (5 Gbps) and three ports that support USB 3.2 Gen 2 (10 Gbps).
