| KBG29 said: You keep compairing the PS3 to the Vita. The PS3 cost $800 to manufacture in 2006, with the most advanced CPU on the market, and one of the highest end GPU's available at the time. PS Vita cost roughly $300 to manufacture at the time it was released. They were 5 years apart. The PS4 had a weak mobile CPU, and a Midrange+ GPU, and cost ~$400 to manufacture when it was released. The PS4 portable in question would be launching 6 years after PS4, using the same chipset as the PS4 Super Slim, which will be very cheap at that point.

PS Vita was way weaker than PS3 with the GPU not even having a quaerter of the PS3's power. Right now there's again a major power gap GPU wise, a possible need for Radeon (no suiting ultra low power version for a handheld device at all) and no powerful enough x86 CPU for a powerful gaming device. Long story short, there will be no x86 PlayStation handheld that is compatible to a PS4. Better not even start talking about game size, internal memory, game cards and stuff like that.
Nintendo's system works because they developed in that direction from the start. And they do have games for a device like that. Being really energy efficient from the start and not giving raw power much importance was a key element for Switch.
And no, a PS5 in 2020 will neither have 128GB RAM nor a 25TFLOP/s GPU. The latter one not even being on the horizon for single GPU high end systems right now and the former one being quite useless and far to expensive.
