The ride never ends.
Iv searched around GAF to see if I can find links to these rumours, but can someone tell me if this has been discussed or what they make of this:

"According to the information, the APU fused on the Xbox One is using an W2W (wafer 2 wafer) multi-module design that allows stacking of one chip on another. The first layer wafer is dedicated to the 28nm HPM Main SOC which was revealed during Hot Chip 2013 with 8 Jaguar cores and a modified Radeon HD 6670 GPU with DX11.1 and OpenGL 3.0 support. The layer beneath it is dedicated to the stacked discrete GPU and the final wafer layer is dedicated to the 32 MB of ESRAM. In development phase, it was revealed by an insider that Microsoft Xbox One could possibly end up with 2 GB of GDDR5 memory in the stacked design in addition to the 8 GB DDR3 that is available to the system. The other information revealed by him were that the Xbox One would have a power envelope of 300W (90W for Main SOC and 95W for Discrete GPU) but during Wireds tear down of the Xbox One, the power configuration revealed that Xbox Ones discrete GPU would be getting around 130-150W of power"
"So what is this discrete GPU itself? The second wafer is supposedly a 22nm SOI design featuring 2304 to 2560 stream processors as been rumored and based off the VI architecture. VI stands for Volcanic Islands which could be another reason why the discrete GPU has been kept a secret since the new Volcanic Islands based AMD Radeon family would be officially announced during the last week of September in Hawaii. If the Xbox One GPU is possibly based on a Volcanic Islands architecture or even a Southern Islands part with around 2048 cores as the Tahiti die, then this would prove to be a massive powerhouse of graphics performance."
more in the link itself....
I personally do not see this happening, why would Microsoft not reveal this, apparently their under a NDA? but they do not need to discuss the volvanic islands gpu, only work out their TFLOPs internally and publish.... this ontop of feeling the need to give away free copies of Fifa14 to shift launch stock (which if rumours are true, are lower than Sonys anyway)
This would be game changing but doesnt smell right to me.
I heard from my sources that Xbox One incorporates quantum computing technology, which would explain all the spinning and why the Xbox One looks different everytime you observe it.
It smells of what it is, Bullshit.
Unless you consider "misterxmedia" an authoritative source, in which case, more fool you.

It was stated that the Xbox one is using 4 command processors... so to calculate TFLOPS;
stream processors * memory frequency * command processors
at their hotchips event Microsoft revealed that their Xbox one chip has 4 command processors (2 compute, 2 graphics)
So...
PS4: 1152 * 800 * 2 : Total 1.84TFLOPs
Xbox One: 768 * 853 * 4 : Total 2.62TFLOPs
So the Xbox One is more powerful than the PS4, at least, TFLOPS wise?
Or is there something wrong with this calculation?

8 Gigs flash is new to me... sounds super awesome! I'm getting a PS4, but that's a great feature. Makes turning the thing into the lowest powerstate probably really fast and super eco. Also Textures and stuff can be pre-loaded for the next level... so load-screens will be very very short, if there will be any at all.
Thinking about it... is the PS4 doing all that directly from HDD? Maybe I'll have to check prices for a low-end 500Gig SSD to put into my PS4.
Didn't see this posted.

Only thing I haven't seen yet was all the Kinect details with a "Time of Flight" sensor.
you wouldn't need a huge coherent memory pool. If you're just storing textures/models that can just be dumb memory. You'd only need to reserve a small amount that you need for shared data between GPU/CPU.
and the limited coherent bandwidth of both consoles looks to be around 30GB/s, so the 176 isn't relevant in that case.

Unlikely as its probably MLC flash (only 10k cycles) which would be worn out fairly quickly.
Its for storage when hibernating the processes.
Flash memory is very helpful for an advanced stand-by state, though.

Its for storage when hibernating the processes. Remember... Games can't use all 5 GB they are allotted... Caching levels can and will be done via main memory
Also... I wonder what the custom graphics/compute command processors are
Uh, is typical flash memory even on par with HDD for sequential read/write???8 Gigs flash is new to me... sounds super awesome! I'm getting a PS4, but that's a great feature. Makes turning the thing into the lowest powerstate probably really fast and super eco.

So, suddenly it's only 28nm TSMC HP and no longer HPM...?
