In consideration of a new or used computer, look to three specifications:
CPU (Central Processing Unit)
The Brains of the computer must be able to keep up with tasks and control the operating system. The more cores and threads the better. This applies to both x86_64 (Intel and AMD) and Arm64 (Apple, Tablets and phones) type processors.
Memory (Random Access Memory)
Memory is used when the computer is turned on. Generally the higher memory is better. In 4 Gigabyte (GB) increments, 8GB is the minimum for large operating systems like Windows 11. 16GB is middling while up to 256GB is used on gaming rigs. Be prepared for high prices for RAM which can drive the cost of the computer to dizzying heights.
Storage
While memory is volatile, storage is for the operating system and files. Again the larger number is better. Start with 128GB of storage as the minimum for many operating systems. As operating systems are updated and files accumulate more storage is necessary. Storage is also being affected by the overall chip shortage created by data centers which will drive costs up. The fastest storage is in NVMe, followed by SSDs and lastly the old school hard drives. Hard drives can be used for long term storage.
Bonus: GPU (Graphics Processing Unit)
GPUs are highly sought after by gamers and video producers. The GPU can be a separate card or integrated with the CPU. GPUs can take the load off the CPU for certain processes like running games or video production. It uses higher GDDR6 memory which is again affected by the chip shortage, driving higher prices.
Conclusion
The average consumer can still buy a good computer at a reasonable, although higher cost. Many are turning to older computers which still have life and better specifications to mitigate costs. Microsoft has mandated 8th or 9th generation CPUs with TPM 2.0 chips to run Windows 11, act accordingly. Do not buy under powered older tablets with only 32GB of storage. Modern operating systems take at least 20 to 30GB just to start.
