Just a reality check for those that think a PS5 in 2019 is going to be truly next gen.
The first thing you have to know is that true leaps in console capability only come with shrinks to technology. You can get refinment and improved performance from the same tech over time, but nothing beats a shrink in the tech itself.
In this current generation we had the PS4 and the XBO launch with 28nm Planar APU's, and now we have PS4 Pro launching with a 14nm FinFET APU. The Pro also benefited from three refinments to the Gaphics Core Next (GCN) tech from AMD, which in hand with the shink in chip size gave it a decent boost, but nothing that is blowing people away.
Now, lets look at the power consumption of the PS4 vs the PS4 Pro. We don't have final actual use test, but we do know the OG PS4 launched with a 250W powersupply, and the PS4 Pro has a 310W power suppply. So the PS4 Pro has a small more energy effiecient chip, based on a more a GPU desing with higher effeciency per Watt, and it is still drawing enough power to require a 60W bigger power supply that the OG PS4.
Looking at the road map to future AMD tech you will see this kind of leap in fabrication size is not going to happen again. We skipped 20nm Planar which was what the original slim PS4 was supposed to be based on, and ended up all the way down on 14nm FinFET due to manufacting problems with that 20nm Planar process.
The next thing in line, and quite possibly where the XBO will be made is on 10nm FinFET and based on AMD Vega. This is the only way the will pull of 6TFLOPs and stay in the confinments of a console. Again, though, the difference between the Pro and Scorpio, will only be 30%. That means something like 1440p - 4k on the Pro and 1800p -4k on the scorpio.
Now if we look ahead to 2019, we see that the plan is for AMD to move to 7nm FinFET, and a GPU code named Navi. This GPU in itself will not be a massive improvement over the Pro and the Scorpio, but will see a decent boost due to being paired with "next gen memory" the revision after HBM2. This is what your so called PS5 would be based on, however, AMD only expects the leap between the PS4 Pro's Polaris GPU tech and the Navi GPU to be about as big as the jump from, PS4 to PS4 Pro.
So, basically, if PS5 comes out in 2019, the best we can expect from a console with a 300W power supply at $399.99 is about 10TFLOPs. That is enough to do a very clean 4K with new bells and whistles, but it will not fundamentaly change the way a game is made. These will still be the same game as you could get on the OG PS4 at 1080p. Perhapps, that will be enough for Sony, and the cadence for new conmsoles will be every three years, only time will tell. IF that is the case though, I fully expect major disapointment when PS5 is revealed, as most people will be let down, because theyare living on unrealistic expectations.
Stop hate, let others live the life they were given. Everyone has their problems, and no one should have to feel ashamed for the way they were born. Be proud of who you are, encourage others to be proud of themselves. Learn, research, absorb everything around you. Nothing is meaningless, a purpose is placed on everything no matter how you perceive it. Discover how to love, and share that love with everything that you encounter. Help make existence a beautiful thing.
