Xbox One Hotchips revisited and XBox One Speculative discussion

fade2black said:
From what I read (long time ago and i don't remember where... my fault sorry :( ) it seemed to me that they established quite early -even before the reveal- that the display planes are three different rendertargets that are composited by hardware. The first two are completely controlled by the game that's running at the moment, so they could be implementing whatever tecnique: rendering skyboxes on one and the rest of the scene on the other, or gui on one and the game on the other. The two could have independent framerates and resolutions and it would not matter, because they are resized and blended by custom dedicated hardware, that's what Astro says and that's why i think he's correct.

The difference with ps4 is that having 2 of them the X1 probably doesn't have to do additional memory ops to blend them because it's the hardware itself that does it, not a specific function written by the programmers of the game. On the X1 that blend function probably only has to give the pointers and modes to the two framebuffers to the fixed function hardware and it would just "render" on the screen the blended result (after of course transforming the blended result and blending it again to the OS plane).
On the ps4, on the other hand, the programmers would have to blend the two game (blending with OS layer is hardware based on ps4 too!) buffers together by software with a rasonably small penalty in speed (after all deferred rendering blends rendertargets together,and is a very viable solution). This is fairly trivial if the buffers are rendered in sync or every other frame, but i suppose it wouldn't be that easy if one layer targets 50fps and the other 15fps, because the fact that don't sync properly would force the dev to manually manage the odd frames to limit the artifacts (I.E. trough frame blending). That's all stuff the X1 almost surely does FAST (as Astro says probably <1 frame fast) by using specific fixed function hardware.But that's pure speculation.. without the documentation for either one i can't be sure.

Actually that! it is pure speculation on astros behalf. He might be right or he is wrong but until their is official documentation from MS then we will never know.

Yeh I don't need anything explaining to me go look at the youtube vid I posted the head of the Xbox one architecture even says it's to do the instant switching not that it will help improve game performance but just to do the instant switch between TV and game.

so who's is right? Astro a forum dweller or Boyd Multerer a guy in has worked on Xbox from the beginning? I know who to believe.

Except the display panes aren't doing any of that....



Around 17minutes, Boyd Multerer says that the display panes are being used to do the instant switching.

He is only referring to using the OS plane. There are 2 others specifically for the game/app that is running. See the VGLeaks dev doc info and the patent. And fyi, MS talked about them in the DF article as a measure to help game performance. So the patent, leaked dev docs, and what you've presumed is some sort of speculation on my behalf (it never was) was confirmed by the guys behind the hardware. ;)

They are both right :D!
If we are assuming the vgleaks docs on the display plane are true -and since vgleaks was VERY close to both console's hardware specs it's reasonable to think they are right on this too- then there are 3 display planes. Two of them do what I and Astro say, the third one is doing what you say.
Finally tech people have started talking about this stuff too.
From the mouths of the engineers:
"We've done things on the GPU side as well with our hardware overlays to ensure more consistent frame-rates," Goossen adds. "We have two independent layers we can give to the titles where one can be 3D content, one can be the HUD. We have a higher quality scaler than we had on Xbox 360. What this does is that we actually allow you to change the scaler parameters on a frame-by-frame basis."

You still don't want to believe me or Astro? Good for you.

It's hard to dismiss it as PR bullcrap if they can't get PR to announce it. ;)

Cool thanks thx. I remember. Seeing a few tech videos and they out right said the they don't know what this one port is for lol by than I stopped watching.
 
AMD latest tweet

ANANtech Final Words:

Final Words
When AMD first told us about their plans for Mantle, it was something we took in equal parts of shock, confusion, and awe. The fact that AMD would seek to exploit their console connection was widely expected, however the fact that they would do so with such an aggressive move was not. If our suspicions are right and AMD is bringing over the Xbox One low level API, then this means AMD isn’t just merely exploiting the similarities to Microsoft’s forthcoming console, but they are exploiting the very heart of their console connection. To bring over a console’s low level graphics API in this manner is quite simply unprecedented.

Other Hint:
AMD True Audio <---> SHAPE
AMD VI Power management <----> X1 Power Island
DX 11.2+

Awesome find Pure! I saw the AMD conference live, and the audio stuff and the real time power consumption scalability really struck me as suspiciously similar.
 
fill this line ....
the spec of VI from Phoronix, Videocardz, Softpedia and others are .......
the R9 290 x =
 
It would be stupid from amd to design such complex chip as x1's, and then not using all the tecnology that microsoft allows them to in their own chips..

:D you will see some connection with a controversial document in the past ....

that was also in that misterx stuff

http://www.extremetech.com/gaming/1...cs-and-benchmarks-of-amds-titan-killer-leaked

Ahead of AMD’s official unveil of the Hawaii line of GPUs, details, photos, and benchmarks of (probably) the Radeon R9-290X have leaked. The photos and benchmarks seem to confirm that the Hawaii XT (GCN 2.0) R9-290X has 2816 stream processors, split among 44 clusters. There’ll probably be 64 ROPs (render output units), and around 176 TMUs (texture mapping units). The GPU should be clocked at around 900MHz, and there’ll be a fat 512-bit memory bus to GDDR5 RAM. The new R9 GPUs are DirectX 11.2 compliant, while the R7 GPUs don’t seem to be. The leaked benchmarks peg the Radeon R9-290X as equal or slightly faster than Nvidia’s GTX Titan, and around 10% faster than the GTX 780 — strong, and if it’s priced right, it could put AMD back in the driving seat.
AMD is expected to reveal its long-awaited Graphics Core Next (GCN) 2.0 architecture later this week, with chips based on GCN 2.0 — Hawaii, Hawaii Pro, and Hawaii XT — following some time in October. We’ll have more discussion of GCN 2.0, and how it helps AMD compete against Nvidia in the gaming and supercomputing scenes, once the official specs and block diagrams have been revealed. For now, we’ll take a quick look at the rumored hardware specs, and some photos and benchmarks from a Korean hardware site (DG’s Nerdy Story) that appears to have got its hands on a Radeon R9-290X graphics card ahead of schedule
 
You know, fanboys here get pissed about fanboys calling microsoft liars, but here we are microsoft fanboys callin microaoft liars.

Ya'll need to make up your mind.
 
Radeon R9-290X
and it will cost about 600 bucks

fyi I am a commodore 64 fan
