1. A single large pool makes a lot of sense, but with Pro they decided to add a separate GB of DDR3, which doesn't really seem like enough to begin with, and strays from the PS4 single pool of RAM, so I dunno which way they will go. XB1X took full advantage of the RAM pool, but it also came at a price.


2. With some XB1X games at 4k coming in at 120GB, on board SSD or flash of around 200GB would be great if the game chosen to play could basically be transferred to the high speed storage. I don't see why they couldn't do this just like how downloads are done in a way that allows you to play quickly, without everything being loaded yet. Not sure how doable this is, but would be nice. Not sure if an SSHD would be beneficial in this scenario either, or if a typical HDD would end up performing similar. With external drives as an option, and slowly becoming the digital norm, while I have a hard time believing PS would go without mass storage altogether and leave it up to the customer (excluding on board), they could use a much smaller drive to save on costs.

  1. I think even the base PS4 had a seperate pool of DDR3 ram. Though i think it was like 256MB or something like that. So really what we saw in the PS4pro is just a progression of that. It really comes down to what they intend to do with the system OS. If for some reason they decide to have as much as 8GB of system Ram, then in that case it would make more sense going for LPDDR4 ram as a seperate ram dedicated to the OS leaving the 16GB/20GB of GDDR6 ram untouched for games.



  2. Well, Right now a 240GB SSD costs around $70 at retail. In 2020 it would probably cost around $50 at retail and for sony, soldering nand chips onto their MB (which costs even less than bulk ordering SSD drives) it would most likely cost them significantly less. So they could be spending like $20 or so for 200-256GB worth of nand flash storage. Another $20 for a 1/2TB mechanical drive. So its doable.


    Or the could spend like $40/$50 on what would amount to around 840GB/1TB of on board nand flash storage and forgo the mechanical drive completely  while still making room for the customer to put in there own HDD if they wanted or supporting external HDDs from day one.
