1.6x Is the GPU speed, it only goes from 550 to 860 or something, which is about a 60% Jump. I don't know how large the CPU jump is, but apparently the CPU used in the PS3 is a modified version of the CPU used in AMD's High End Laptop lineup. However Laptop CPU in a home console? That's probably done to cut power useage because I hear the original PS3's used 200W to run them, and that's more then a mini-fridge.

PS4 gets rid of the bottleneck that the PS3 had with a strong GPU and 3x more VRAM, but like I said before the GPU is only 9x more powerful then PS3's and the VRAM is only 3x more. It's not going to make the PS3 tens of times more faster if it only directly increases the bottleneck drawback 9x.

Theoretically PS4 can be up to 9x more powerful, but realistically things like the slow GPU speed, weak CPU's, and small upgrades in PS3's other bottlenecks, like VRAM, PS4 is only going to be 6-9x more powerful.

 

Uhm... are serious man? That's just the core clockspeed, it say's nothing about processing power, PS3 is using 8 year old technology. I think you should read into some facts about computer technology before posting this kind of nonsense.

PS3 gpu processing power: 200 GFLOPS

PS4 gpu processing power: 1860 GFLOPS

That's over 9x. And just 3x more VRam? Ps3 had 256mb fixed amount of ram at 22 gb/s. Ps4 will have 8000mb shared ram at 176gb/s, they could use as much of that as Vram as they want. Let's say 5000mb of that for vram. That's 20 times the amount of Vram the PS3 had at much higher speeds, and close to the amount that Nvidia's $1000 Titan card has.

And it's an 8 core cpu based on amd's new Jaguar core, even at 1,6ghz that's about equal to a 2ghz cpu from amd's current line-up. Or a quad-core running over 4ghz, that's not that bad either.

If you look at my very first post on this thread, I do mention the GPU processing power (I also mention that the demo was played on a PC with around 6,000 GFLOPS, or on a processor 3x as powerful as PS4's). Here I'll quote it for you

I'm arguing that the PS4 is at most 9x more powerful then the PS3, mostly because of the GPU Processing power and increased RAM. It can't be more then 9x more powerful because with the sole exception for RAM, none of the components increase by anything greater then 9x, with some aspects like the Clock Speed, and GPU Bandwidth (This was a bottleneck for PS3) increasing by as little as 1.6 and 3x.

VRAM =/= RAM, PS4 has about 176GB/s VRam Bandwidth, and the PS3 has 22.4GB/s, which is about an 8x increase (I said 3x by accident just there.

As for the CPU, it's not bad, but it's still a CPU designed for laptop performance, not PC Tower performance. PS3 also had 7 CPU's with 3.2Ghz per core, which isn't that much different then PS4's. I'm not sure PS4's CPU's capabilities, but PS3's CPU's do 25GFlops and double precision. I think the AMD CPU does between 60-90 GFlops, so the CPU jump is in the range of 2.5-3.5x more powerful.
