Microsoft: Xbone Is 3x As Powerful Than X360 (Phil Spencer Twitter: It Was A Mistake)

I don't think I said there was "barely any improvement", I said the GFLOPS is 9x as much, but the speed gain isn't as much.

As you can see, the Core clock rate is only a 3x improvement in the PS4. In comparision to the 9x improvement inGFLOPS, a 3x improvment in Clock Speed isn't much. I don;t understand why 2-3 people quoted me and laughed, do I have my facts wrong?

Like I showed above, it's only a 3x improvement. Still big, but not crazy compared to the FLOPS increase of 9x.

I think it's the way I say things, people get offended. PS4 is obviously a pretty powerful system, I'm just saying it's not a huge jump, just big. From PS2 -> PS3 it was like a 25x in performance, now from PS3 ->PS4 it's about 9x, and the Clock Speed is only 3x of a jump. 3x < 9x < 25x, lol.

Think of clockspeed this way...

The clockspeed is how fast a car can go, in the PS4's case, 550 kilometers an hour.
Think of the shaders as how many cars are on the race track, the PS4 has 24 cars going at 550km.

Now the PS4 GPU can go 800km an hour.
However it has 1152 cars on the track.

Who will have the most cars win? Hint: PS4 and it's a massive difference.

How was the PS3 only a 10x jump from PS2? I read that the PS2 only processed data at a rate of 6.2 GFLOPS. PS3's theoretical limit is 230 GFLOPS, that's almost a 40x jump (but once you contribute things like clock speed, and bus width, it's more like 25-30x from what I read).

Anyway, Microsoft themselves say the One is 8-10x better then the 360. PS3 was already more powerful then the 360, so PS4 being 9x better then PS3 puts PS4 a little better then the One (which is is), and in agreeance with Microsofts statements.

Don't be sore CGI, I expect better from you.

You claim over 15x, then agree with me, then change your mind, and now you're sore because I kept track of how you claim to be right all 3 times, but argue 3 different power figures? Then you quote people to disagree with me on something complete unrelated and attempt to demean me? Did I start to demean you when you were blatently incorrect about PS4 specs?

PS4 GPU clocks speed is only 3x faster then PS3's, I wasn't wrong when I said that, and the evidence is above.

It's one thing to be wrong in a debate and not conceding, it's another to start boosting intelligence over others when you have no reason to do so.

You're grabing the GFlops numbers.
For starters, there is more to a processor than floating point, you have integers too! However GFlop is a one-dimensional and application-specific metric, it's not comparable.

Secondly, take the GFlop numbers with a grain of salt, or 10. - Microsoft and Sony have a financial vested interest to inflate their GFlop numbers to make their system look more superior, it's marketing pure and simple and you fell for it.
This time around as Microsoft and Sony are using a mix of Low-end and Mid-range hardware, the PC can keep them more honest.
