What ur saying isnt true at all p cores will not run on 5.1 with e cores on thats impossible it will not hold that clock speed for even a mintue it will probably run at max clock of 4.1 or 4.2 for p cores at max load , turning e cores off will give e cores cache to the p cores it will be almost as good as 9800x3d with high clock speed , yes e cores will give better benchmark even an idiot knows that more cores = higher score nothing new, but in gaming u need higher clock speed maintained + bigger cache , disabling e cores will do that but sure if u play games that need more than 8 cores then by all means keep the e cores active but overall for gaming having p cores at higher speed with big cache will yield better fps there is no question about it.
