Will the PS4 represent 50% better performance than the X1

The system floating point performance of the PS3 is twice the system floating point performance of the Xbox 360. That is all I am saying.

First GPU.

RSX is a weak variation of GeForce 7800 GTX... the 7800 GTX have 165 GLOPS performance... you can say RSX run a little faster (450Mhz to 550Mhz) but in fact the RSX is a weak variantion and not strong one... in any case the RSX have at maximum 200GLOPS.

Xenos is a unified arch with 48 vec5 running at 500Mhz... so easy that I will give you the full number directly: 240GFLOPS.

RSX: 165-200 GLOPS
Xenos: 240 GLOPS

Yeah... the GPU differnce is that big.

CPU.

Xenon is a PPC based arch... the VMX units (like the SSE units in Intel) in a 3-core PPC runnin at 3.2Ghz can archive at maximum 80 GFLOPS.

Cell it is the difference here...each SPU can archive 25.6 GFLOPs... PS3 have 7 of them on... so 179,2 GLOPS (I will use 180 GFLOPS).

Cell: 180 GFLOPS
Xenon: 80 GFLOPS

Overall

PS3: 345-380 GFLOPS (the articles in Intenet shows PS3 with 400 GLOPS because they use the FLOPS of the full enable Cell with 8 SPUs)
360: 320 GLOPS

In the best case schenario the PS3 is 20% more powerful than 360... the best case is how much you used the power of Cell in the right way.

In FLOPS the difference is that but remember it's ways hard to use these FLOPS from Cell that makes the diffence be less than what the theorical shows... and 360 have a better arch for memory so even more easy to use memory in 360 than PS3.

The use of Cell for gaphics is a hell of difficult... the 360 have a easy use of 240 GFLOPS for graphics here.

Xbone x PS4

Exactly the same CPU so I won't make the maths here... GPU 50% more powerful for PS4... we never saw a generation with this gap in power between Microsoft and Sony (we saw a even bigger with Nintendo x Sony/Microsoft).

Good work, but you are forgetting a few bus bottlenecks and some other problems.  My calculations put the Xbox 360 and PS3 are more like 5% of each other's power.  (Remember they were both mostly developed at the same place, at the same time at IBM.)

“We never saw a generation with this gap in power between Microsoft and Sony”

Remember the Xbox was more than 100% more powerful than the PS2.  And outside of a few exclusives, how much difference would you say you saw between the two?

Being 100% more powerful is when you will just start to notice.  We will really see the difference compared to current gen’s as the next ones are 8-10 time more powerful than current (X360 PS3.)
