| fatslob-:O said: It's pretty bad, we're probably going to have to deal with reconstructed 1080p like Killzone: Shadow Fall multiplayer to get a leap in next gen visuals ... HBM won't be feasible for next gen consoles by then ? HBM technology when it first hit the market (AMD Fiji) will be 5 years old by then if next gen consoles release in 2020 and 6 years old if they release in 2021 ... No more than 4GB for the console OS is fine and I'd prefer it if we also stick with DDR5 since LPDDR4 will be dated and not have much of future in terms of volume production while DDR5 will be produced for many years to come ... |
I think you are underselling the value of GDDR6 and over estimating the needs of bandwidth in games next gen. 800GB/s is more than enough for next gen games. And sure as hell is a far cry from bandwidth saving checkerboard rendering techniques.
Secondly, while HBM as a tech will be 5yrs old by 2020, that has nothing to do with the maturity of the tech. Eg the electric car has been there before ice cars were made but are only mature enough today over 100yrs later for the mass market. Same applies here. HMB or even HBM2 may be well known technology by 2020, that doesn't in any way mean it's ready to be mass-produced to the tune of 30M packages reliably every year for both the PS5/XB2. Hell even Samsung is hedging their bets with regards to the tech as opposed to doubling down on it completely .
As with LPDDR4, it really doesn't matter if it's dated by then. you won't be seeing that age of your ram on the home screen. What's important is it's price, performance and ease of use. And you do realize that LPDDR4 is basically smartphone memory right? That's what you see in phones. So basically I'm saying the ram used in the next gen console for the OS will be a smartphone memory solution. Cheaper. Uses less power. Smaller form factor and less complicated. If LPDDR4 isn't being used by the smartphone industry by 2020... Then it would be whatever replacement they are using that I expect to power the OS of the PS5. Unless you feel smartphone memory bandwidth is too low to stream Netflix and YouTube and manage some system operations.
