Going to drop a bombshell.

Not all HD7000 series GPUs are the same.

Some AMD HD7000 series GPUs only support the DirectX 11_0 feature level, yet they are or will be DirectX 11.2 compatible with a driver update. Only the Xbox One's GPU is DirectX 11_1 feature level compatible. The "Tahiti"/"Pitcairn" line of AMD GPUs are first generation GCN, which is what the PS4's GPU is based on. The Xbox One's GPU is based on the "Bonaire" GPUs.

Why does this matter, it's only DirectX right?

No.

DirectX 11_0 level GPUs only support Tier 1 - Tiled Resources. DirectX 11_1 level GPUs support Tier 2 - Tiled Resources.

Yes, the PS4 will have similar capabilities as the Xbox One, even the Voxel Cone Ray Tracing. The difference is that the Xbox One's GPU feature full hardware (Tier 2) where as the PS4's is software based (Tier 1).

As mentioned in the original post, Voxel Cone Ray Tracing uses Tiled Resources. Both the Xbox One and PS4 are capable of supporting Voxel Cone Ray Tracing, but the Xbox One's implementation is hardware based. Meaning faster.

That is the secret sauce.

You've posted about 3 or 4 secret sauce posts, so is this the *one* now... or are you going to go with something else in a few days?

Instead of seeking to convince others, we can be open to changing our own minds, and seek out information that contradicts our own steadfast point of view. Maybe it’ll turn out that those who disagree with you actually have a solid grasp of the facts. There’s a slight possibility that, after all, you’re the one who’s wrong.

LOLOL are you clueless ?

You realize that tiled resources and PRT's are the same thing right ? That also means that the PS4 will support tiled rendering via the opengl extension AMD_sparse_texture.

How do you know that the xbone is based on the bonaire ? if anything its more similar to cape verde in performance

And that last part that is bolded is wack lol, I think you don't know what your talking about.

There is only one hardware chip in a retail product that supports it DirectX11_1 and Tier 2 - PTR.  One that just coincidentally shares similar unit counts to the GPU in Xbox One.  That is the Bonaire-based AMD GPU.

Why are bringing up shit time and again? And what the hell has "unit count" to do with hardware features?

In every slide Sony has shown about the gpu they mark it as having DirectX11.2 compatible features (they even label it as DirectX11.2+)

Yes, I do know they are the same thing. 

The differences it that Tier 1 support is software based, Tier 2 is hardware based.  The resource mappings are done in code on Tier 1, they're done by the GPU in Tier 2.

This is me sitting while I laugh at you.

There are no Tier's of PRT's. Deal with it. AMD has added hardware implementations on ALL GCN GPU. It doesn't just apply to bonaire but to every AMD radeon hd 7000 series that doesn't use a 40nm process node. Your trying to hard to be like ethomaz lol.

Edit: It's over I caught you red handed for being a fake in the knowledge of the hardware world.

Not this again. I'm getting tired of this. Still all the Xbone fans are allowed to keep on dreaming.

No offense but  no, most Xbox fans (like myself) are currently happy with the Xbox One.
