2021 ROG Strix GT35 vs. Dell Optiplex 5090 SFF
The 2021 ROG Strix GT35 and the Dell Optiplex 5090 SFF were released in the same year, 2021. The 2021 ROG Strix GT35 has a full-tower form factor that can accommodate a large motherboard, multiple graphics cards, extra storage, and better cooling solution. The Dell Optiplex 5090 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 2021 ROG Strix GT35, you have options to configure it with a 125W 11th Generation Intel Rocket Lake 8-core Intel Core i7-11700KF up to a 125W 8-core Intel Core i9-11900KF with a boost speed up to 5.30 GHz.
While Dell Optiplex 5090 SFF has configurations with a 58W 10th Generation Intel Comet Lake dual-core Intel Pentium Gold G6405 up to a 65W 8-core Intel Core i7-11700 with a boost speed up to 4.90 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 2021 ROG Strix GT35 up to 64GB of 3200MHz dual-channel DDR4 memory. For Dell Optiplex 5090 SFF, it supports up to 64GB of 3200MHz or 128GB of 2933 MHz 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 12 USB ports available on the 2021 ROG Strix GT35, two more than the Dell Optiplex 5090 SFF that has only 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 2021 ROG Strix GT35 has nine USB Type-A ports and three USB Type-C ports. It has two ports that support USB 2.0 (480 Mbps), four ports that support USB 3.2 Gen 1 (5 Gbps), and six ports that support USB 3.2 Gen 2 (10 Gbps).
For Dell Optiplex 5090 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), five ports that support USB 3.2 Gen 1 (5 Gbps), and one port that supports USB 3.2 Gen 2 (10 Gbps).
