No lol

Neither Xbox was 50% more powerful than PS2... PS3 is not in no way 50% more powerful than 360.

PS4 is.

well if you look at the total performance in teraflops, which seems to be the cool thing to do these days, the PS3 was twice as powerful as the 360.

No.

The 360 GPU was way better than PS3 GPU but the Cell was better... overall PS3 was better... the FLOPS count for PS3 is not that high too... don't believe in wrong counts that seems to make the PS3 GPU have 400GLOPS performance lol

I guess not or maybe even less powerful based on an article.

Source?

From what I've read, it's a 10% difference between the PS3 and 360 in terms of FLOPS.

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.

Though nowhere near 50% i'd say.

although 50% really is a sort of misleading term.

i'd also note 50% is really sort of a silly metric, any percentage is.  Since graphics are mostly subjective... and even by the numbers stuff like frames per second and other number metrics are all going to very widely by the design of the game, and programming of the game.

Subjectivly, i'm not even sure the PS4/Xone will be seen as having 50% better graphics then PS3/360.  The higher you go up, the harder it is to win people over graphics wise.

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).

While I will confirm Sony has the better GPU, they messed up again.  GDDR5 RAM is great for graphics, it should make nice pretty pictures – But unfortunately, it comes at a cost - huge latency.

I'm not talking about twice as bad, or even 5 times, but 7-10 times as much latency as DDR3 memory.  It will cripple all the other advantages they put in it – like the wider bus width, speed, etc.  It’s really a shame.  It will effect everything thing that isn’t just a picture (AI, Game play, etc.)

It reminds me of a business person making a decision that doesn’t understand the consequences.  Like the people that messed up the cell, or the person that stopped the first Kinect from having it’s own processor.

The best estimates I have seen is that, because of these blunders, for most games the PS4 will run just a little bit behind the Xbox One.  Hence, what you are finding with the lower rate.

Measuring in flops is pointless, it's not an accurate representation of performance.

For starters, the Cell will *only* achieve anywhere near it's theoretical performance with linear equations, otherwise it's orders of magnitudes slower.

The Xbox 360 and PS3 are very different beasts from an architectural perspective, different memory set-ups, vastly different GPU's, different CPU's etc'.
The Xbox One and PS4 on the other hand are almost identical from an architectural perspective, minus the differences in the memory systems.

Whichever way you cut the cake though, with the Xbox One's 50% slower GPU... There is going to be differences in image quality later in the machines life when developers push the hardware, think: Less Geometry, Texture resolution due to less available Ram, Particle counts severely scaled back... That sort of thing.
