Well I had to vote for Intel because I have no experience with AMD. Unfortunately I'm stuck on older/sub par technology like Intel ATOMs, Celeron and an old core 2 duo. The most powerful CPU in this household is an i7 seventh gen which isn't my computer so I hardly use it.
I play a few games that are available both on the Windows OS and Android. The funny thing is that those games play equal to or better on my low end Samsung tab-a than they do on that Dell with the i7 and 16gb of RAM. I've never tried "real" games though so it might be a totally different story there.
I've been wanting to upgrade (lol, if you can even call it that in the year 2020) the CPU in an old Dell Inspiron 1545 from a t4200 (2ghz dual core) to something faster.....maybe even get it up to 2.5ghz or close to 3! Lol. Just yesterday for the first time in that computer's life (which was born in 2009) I upgraded the RAM from 3gb to an astounding 4gb. Then I installed the 64-bit version of Windows 10 and the machine chugs along at a not speedy steady pace.
The Inspriron 1545 with that setup runs circles around the weak old netbook I experimented with earlier today. It is a Toshiba nb505 netbook from 2011 which came stock with Windows 7 starter, an ATOM n455 CPU and 1gb of RAM. I swapped out the 1gb and put in the max RAM it would accept which is 2gb. Then I just wanted to see how Windows 10 32-bit would perform on it and I wasn't surprised when that little machine gave all it had just sitting idle. The CPU maxed out and stayed there even when nothing was going on, no surprise.
I also tried cloudy ready on that netbook, the performance sucked. I've tried a few different Linux distros and the experience has been mixed with those. Whatever variation of Puppy linux didn't do too bad with it but I believe the machine is better off as a paper weight.
A couple months ago I purchased a used Acer One 10 tablet with Windows 10 32-bit on it. It has the ATOM x8350 cpu and a grand total of 2gb or RAM. It's pretty much equal to (but with better battery) to the junk RCA Cambio tablet they still sell at Wal-Mart. The Acer is more of a novelty than anything else because for actual computer work I use an actual PC lol. It does have rather good battery life though so it can be convenient for simple tasks. One bad thing is the limited 32gb of memory it has as Windows 10 keeps bloating up every day it seems.
I have another laptop (an old Gateway) with a Celeron b800 cpu which runs up to 1.5ghz and has 2gb of RAM. Windows 7 was thriving when that PC was released but that one too I will put some more RAM in and try Windows 10. If it wasn't for Microsoft cutting off support for Windows 7, I would probably stick with it. I only say that because I have outdated computers lol
Enough rambling from me
