Nothing more than basic office work, basic web browsing.
Even video playback is tough on old chips because they don’t support newer codecs like H265 and AV1, so by default anything over 720p on youtube will struggle and you ll need H264ify extension to enable the old h264 streaming codec that they support.
Personally, i’d rather buy a modern midrange/low end android tablet, +BT keyboard/mouse. People forget to mention that old laptops typically had garbage 720p screens and speakers and run with 4GB RAM and dead slow hard drive. You won’t be able to install modern windows anyway, and they run even worse after doing all the security updates on them.
You’d have to have a very specific usecase to use an old dual core x86 laptop running windows 7 or lower rather than pick a modern low end Android tablet. Windows 11 would run ok with just 2 cores of the newest Zen4 and Raptor Lake architectures that would be better than 6core laptops back in the day, but you don’t have modern cores in those dual core laptops. You have garbage in today’s standards.
How do mobile gpus like snapdragons 8 gen 3 iGPU and the likes?
If those phone GPUs are compared to apples M1/M2, how do they do against intel and Amd now?
