Right so 52 CU's even at a fairly optimisitc1.5GHz clock speed is going to give 10TFlops. A lot of rumours and wishful thinking I have seen on other forums are expecting it to be around 14TFops. I just don't see how that is happening.

Wow, so no secret sauce and standard x86 architecture.. I'm shocked I tell you.
So we still need to know, HT yes or no, how much RAM (and what type), how many TF and the price.
Edit: I'm more excited about audio enhancements and a new upgraded PSVR.

Does OpenGL support RT, or RT in the manner which DXR is capable of doing? If not, then a distinction can be made. That Sony's way of doing RT might be more hardware eccentric, rather than a OpenGL driven solution of doing RT (which I haven't seen as of yet, other than some hack projects running terrible).
The API used is irrelevant as to whether a solution is more hardware or software.

The latest Gonzalo product code suggests a 1.8GHz GPU clock.
Yes, I didn’t meant to imply PS5 DXR usage - merely that it’s simply a compute operation enabled by some API.
Hardware-accelerated would be more apt, no? Any attempt to do RT is going to do so leveraging features of the underlying hardware.
How? Please explain. I don't claim to know everything, but willing to understand. How are different API standards not relevant? I always thought OpenGL and DirectX have very distinctive ways towards rendering vector graphics. Meaning, if DirectX (DRX) is capable of rendering raytracing across the hardware in manner where specialized RT logic/cores aren't necessary, does that apply to the current OpenGL as well?

I'm expecting a hybrid system, perhaps something like Apple's 'Fusion' drive approach. If they're doing something ridiculously fast as claimed ("Cerny claims that it has a raw bandwidth higher than any SSD available for PCs") then it's going to be small in size. Or expect this box to be a lot more expensive.
Of course it is possible that Sony are using some genuinely new tech with the promise of speed, reliability and size. Actually, you can probably scratch reliability or rather the number of write-cycles. There are lots of promising pre-production solid state storage technologies whose only drawback is that it's limited to < 1,000 write-cycles which probably wouldn't be an issue in a console.

Yes same for Vulkan etc. APIs are irrelevant in the way a feature is implemented in the GPU. AMD/Intel/NV choose the way in which they accelerate said feature etc.
The API is there to generalize the functions in a way that developers can expect. As APIs are there to generally make the lives of developers easier by providing a set of functions that they can bank on working as long as the API is supported.
So specific set of functions always takes in the same type of inputs and always outputs the functionality as listed on the description.
The role of the drivers, supported by the IHVs or in this case, sony, would be responsible for determining how the function is carried out through the hardware, exposing whichever hardware features they wish to or not wish to.

There have been a lot of interesting patents out of AMD the past few years, and Sony/AMD engineers are even on some of the same patents.Very fun times ahead...
The RT is fake, an insider told me Sony is using a cell powered GPU to do Ken tracing, this thing does 10million Kutaragis/second... Let that sink in....
Though with limited performance making it a very costly, and thus to be avoided, solution.
I have to correct myself though, that the article only says the GPU supports raytracing, and nothing about acceleration, so yes, it could just be RT on compute same as any DX12 class GPU, which would make it a feature tick-box rather than something useable and used.

Agree. They probably felt like they would be criticized if they didn’t support it, or that they expect MS to say they support it and don’t want to be left out.

Don't, at the very least there will be special instructions to accelerate/accommodate ray tracing. The fact that the system architect was keen on mentioning the feature in the context of a custom navi GPU and a custom ray traced audio unit gives a strong indication of some sort of hardware solution.
I think this thread has had enough of console RT doubters at this point.
Audio revelation is interesting, MS went this route with current generation and many of us said it was a waste of resources because unless you have an expensive speaker set up or resign yourself to using headphones you won't notice the difference.
I think that's true here too, perhaps it makes sense if you think VR will take off but I'm somewhat skeptical that advance audio is something much if the public is in a position to take advantage of.
