Processor

The Central Processing Unit (CPU) is like the brains of your desktop computer. Its performance determines how fast and responsive your PC is.

For Lenovo IdeaCentre A540 AIO (24”, Intel), you have options to configure it with a 35W 9th Generation Intel Coffee Lake quad-core Intel Core i3-9100T up to a 35W 8-core Intel Core i7-9700T with a boost speed up to 4.30 GHz.

While Lenovo IdeaCentre A540 AIO (27”, Intel) has configurations with a 35W 9th Generation Intel Coffee Lake quad-core Intel Core i3-9100T up to a 35W 8-core Intel Core i7-9700T with a boost speed up to 4.30 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.
