Lenovo Legion Tower 5i vs. Alienware Aurora R12 Desktop
The Lenovo Legion Tower 5i and the Alienware Aurora R12 Desktop were released in the same year, 2021. Both systems share the same 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 Lenovo Legion Tower 5i, you have options to configure it with a 65W 10th Generation Intel Comet Lake 6-core Intel Core i5-10400 up to a 65W 10-core Intel Core i9-10900F with a boost speed up to 5.20 GHz.
While Alienware Aurora R12 Desktop has configurations with a 65W 11th Generation Intel Rocket Lake 6-core Intel Core i5-11400 up to a 125W 8-core Intel Core i9-11900KF 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 Lenovo Legion Tower 5i up to 64GB of 3200MHz or 128GB of 2933MHz dual-channel DDR4 memory. For Alienware Aurora R12 Desktop, it supports up to 64GB of 3400MHz 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 7 USB ports available on the Lenovo Legion Tower 5i, eight less than the Alienware Aurora R12 Desktop that has 15 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 Tower 5i has six USB Type-A ports and one USB Type-C port. It has two ports that support USB 2.0 (480 Mbps) and five ports that support USB 3.2 Gen 1 (5 Gbps).
For Alienware Aurora R12 Desktop, it has thirteen USB Type-A ports and two USB Type-C ports. The PC has six ports that support USB 2.0 (480 Mbps), seven ports that support USB 3.2 Gen 1 (5 Gbps), and two ports that support USB 3.2 Gen 2 (10 Gbps).
