This is only true if the GPU tech and manufacturers are different, AMD flops and Nvidia flops aren't 1:1, however, both the PS4 and xbox one are using the same manufacturer, AMD, with effectivly the same GPU tech, the difference being that the PS4 has 18CU while the Xbox one has 12CU....so in this situation using FLOPS as measurment is far from pointless, rather it makes it easier to gadge the difference with a higher accuracy of true performance.

No, it is pointless, please read my post within it's entire context. :)
An example would be:
A GPU can have 10,000 Teraflops, but if a GPU with 1 Teraflop has say... 10x the Geometry performance, then graphically, it can pull ahead, because the world won't be all flat boring surfaces. :)
Besides, we all know that the Xbox One has 50% less GPU hardware, but the question begs on what other parts of the GPU are in actual fact exactly the same as the PS4, we probably won't know untill release.

Your example is not applicable to the PS4/Xbox one because they both have almost identical GPU tech.
Now if the Xbox one has a ray tracing unit, then yeah even with a weaker GPU the lighting the Xbox one would have would crush whatever the PS4 could do, then your example would be applicable.
So far though the specs which have been revealed were correct for the PS4 so we can currently take it that the xbox one rumoured specs are true as well...obviously taken with a grain of salt, but again there has been nothing to say that the Xbox one has anything special that all of a sudden change the playing field, if there was Microsoft would be talking about it especially with the PS4 specs officially being revealed....funny that Microsoft is being so vague, almost Nintendo like….
Your right though, once these boxes are released, they will get gutted and will find out exactly what's underneath the xbox one hood....I'm just saying that there probably won't be anything new that we don't already know, the gutting of the box will just confirm what’s been rumoured.

Well that's the thing, things might not be as similar as you think. The X1 has four LZ77 Move Engines built into the GPU that compresses and decompresses in the background. Something that the PS4 GPU obviously does not. The audio chip in the X1 is supposedly a powerhouse as well (presumably to handle Kinects vastly improved voice recognition, amongst other things). This might end up like the PS3/360, one system "appears" to be more powerful but in the end they end up much more comparable because of other factors beyond the Teraflop count.

The move engines are nothing more than part of the DMA setup, all they've added is some extra compression units, to say that it's something over the PS4 when the PS4 also uses DMA and also have compression units is disingenuous. To be clear, the DMA on the Xbox one has been modified enough in order to keep the ESRAM full and the GPU fed, something the PS4 doens't need to worry about since it has no ESRAM, in other words the Move Engine are nothing special, their just there along with ESRAM to mitigate the low bandwidth of DDR3 memory. The PS4 simply has 8GB of fast ram, 176GB/s, accessible by both the GPU/CPU and this is why neither ESRAM or Move engine are required, 2 approaches to achieve the same goal, the PS4 just achieves the goal better with less headaches.
As for SHAPE, the sound chip, yeah it's a power audio processor from what I understand, however, like you said it'll most likely there to handle kinect related audio processing. the PS4 also has dedicated sound hardware, but since it's not doing kinect like stuff, it's not required but again it's not to be taken as an OMG xbox one has mo powa!
Just keep in mind, Microsoft like Sony love to tout their power or advantage, Sony have officially reviled their system specs, Microsoft has not, all they've been talking about is the power of the 'Cloud' while leaving the system specs vague....kinda strange considering they touted the power of the 360 in the past, and their still touting power now, they’re just keeping quiet and vague about the power of the Xbox one, to me this is telling as Microsoft would not be one to keep silent if they indeed had better specs, but currently it seems that their being silent because indeed their box is weaker than the PS4, hence, the emphasis on the cloud.
