i5 laptops should be just about doable for the price, and in theory any new i5 laptop should give good performance.
One thing to remember is that clock speed it not everything and that modern intel processors will automatically overclock (turbo mode) when more power is required.
I have a laptop with an 8250u and 8gb ram and it seems OK for rail simulator 2018 and Euro Truck Simulator 2, whilst the processor by default is only 1.6ghz it will go up to 3.2ghz if required.
Also number of processing cores and wheather or not it supports hyperthreading will make a difference esp. if the clock speeds are the same. The cpu ratings on the pass mark website are a good way of comparing power.
Lastly, going for a traditional spinning hard drive rather than a SSD at the lower end will get you a LOT more storage for your money.
maybe more storage capacity, but SSD is MUCH faster for operation and boot up.
I guess it depends what you want it for. If it's just a cheap lightweight casual use item then HDD will be fine. if you need it for any more productivity stuff like excel sheets or more "hard" gaming then go the SSD route, but go for a bigger capacity.
SSD's slow down markedly the more used up space they have.
for desktop use I wold NEVER go back to purely HDD, solid state drives are night and day difference, so I use one as a boot drive and additional HDD for storage.
you won't get much in laptop terms for £200 these days.
this is a pretty good spec for £300 if you can stretch to that

amd is better for integrated graphics,if you are concerned about gaming.
intel is better for browsing speed etc...
Unfortunately at this price level you would be stuck with intel integrated graphics which is generally 50% the performance of AMD.
(the high end intel laptops have a seperate nvidia card)
however, the performance of AMD cpu side in A series chips is about 50% of intel,albeit they are generally a lot cheaper too.
so it's horses for courses.
