I know the ps4 is beastly and yes gddr5 is the better choice In laymen terms gddr5 Fat pipe slow stroke the fat pipe allows for parallelism and large chunks but can afford
high latency due to the fact that it can do other things while its waiting like «rendering» on a gpu cough cough gaming with tons of gpu accelerated post processing etc etc. ddr3 Skinny pipe Fast stroke not
too skinny but smaller I / O channels and only writes or reads per cycle however the
latency is much lower meaning compute intensive tasks can access ram in smaller chunks much more quickly.
