Well, a lot of people here would have loved to have 10-year old Xeons in their motherboards; while power hungry, I guess they would make good CPUs since they have good cache sizes. But no, there's no Xeons in our offers here. What people get here now are Intel Pentium and Celeron-branded CPUs, or N-class CPUs, with the onboard GPU only, 4GB RAM and 1 TB HDD running unlicensed Windows with understandable results. But when you are a digitally illiterate parent seeking to purchase a first PC for your children of school age, this looks attractive enough at a good price point.
> Intel Pentium and Celeron-branded CPUs,
Don't look at the branding. Look at the core type, count, and speed (maybe).
It's been a while since I shopped Intel, but they used to typically release a low core count/lower clock speed Pentium/Celeron on the mainstream cores, often with no hyperthreading. These were typically low cost and could be a good value, you'd get decent single core performance because it's the newest architecture and multicore performance would be iffy but you can't have everything.
> N-class CPUs
These are definitely worth avoiding most of the time. Usually twice the cores, but much less performance per clock. Never feels fast for interactive work. But they make sense for some situations. Some of these get an n3 branding to trick people looking for i3s.
