Lenovo Legion T730 vs. Dell Optiplex 5070 Tower
The Lenovo Legion T730 and the Dell Optiplex 5070 Tower were released in the same year, 2019. The Lenovo Legion T730 has a full-tower form factor that can accommodate a large motherboard, multiple graphics cards, extra storage, and better cooling solution. The Dell Optiplex 5070 Tower 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 Legion T730, you have options to configure it with a 65W 8th Generation Intel Coffee Lake 6-core Intel Core i5-8400 up to a 95W 8-core Intel Core i9-9900K with a boost speed up to 5.00 GHz.
While Dell Optiplex 5070 Tower has configurations with a 54W Intel Coffee Lake dual-core Intel Pentium Gold G5420 up to a 65W 8-core Intel Core i7-9700 with a boost speed up to 4.70 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 Legion T730 has two RAM slots that support up to 32GB of 2666MHz dual-channel DDR4 memory. On the other hand, the Dell Optiplex 5070 Tower has four RAM slots that you can upgrade 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 8 USB ports available on the Lenovo Legion T730, two less than the Dell Optiplex 5070 Tower 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 Lenovo Legion T730 has eight USB ports USB ports that all of them are Type-A port. It has two ports that support USB 2.0 (480 Mbps) and six ports that support USB 3.2 Gen 1 (5 Gbps).
For Dell Optiplex 5070 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).
