Removing sticky on this thread. If a bulk of new info comes in, we can re-sticky it.

Orion,
What about DX12 also hitting mobile? It does not mean mobile devices will have titan on board.
The same could be with xbox one - it will receive a full set of features, but adapted and developed specially for xbox one.

Orion, What about DX12 also hitting mobile? It does not mean mobile devices will have titan on board. The same could be with xbox one - it will receive a full set of features, but adapted and developed specially for xbox one. Here's the thing. We don't know to what degree DX12 will be implemented on mobile phones. We can directly assume that you can't even do the stuff the old PC cards can do. Yet we know that the Xbox One will fully support DX12 and we also know it is required you buy new hardware for full implementation. So, no. There is no comparison between the Xbox and Mobile. You're reaching to lower your expectations, and that's fine. However, all the information you need to know to back up the Xbox portion of the information, you have. No need to lower your expectations. It's been answered definitively. |

After reading all, my Opinion is:
They behold Dx12 for boost the hardware in backhand til the near future, after MS seeing what the other company do, they roll it out 1.83 TF SP.
This was the sentence from a MS Officer i think, some of the best software heads, write this software.
This was dx12, and the x1 was 2014 console, than get Don Mattrick back!
Special Custom Hardware to outbounce many cpu/Gpu work to 15 co prozessors, move engines, scaler (nice work in beta). And they fired Marc Whitten. Why did they do this, if dual render threadable gpu is there? But the Powerbrick is there, stacked soc, but i think there is no stacked amd cpu. AP says no second gpu, no stacked- what is with multicore gpu, dualpipeline gpu?

No offense to unbiased warrior but I am getting tired of people constantly saying the Xbox one's gpu is an Amd 7770. It is not in any way a 7770! In fact the only thing it has in common with a 7770 is a similar tflop number. The Xbox one gpu has 2 graphic command processors and 2 compute command Processors. The 7770 only has 1 of each. The Xbox one has 12 compute units. The 7770 has 10. The Xbox one has several Special purpose processors on board tha the 7770 doesnt have. And finally the Xbox one gpu is based on the latest version of GCN (sea islands) where the 7770 is based on southern islands. The Xbox one also has full hardware support for Tiled Resources where the 7770 doesnt. Sure the flop output is similar to the X1 but Flops arent the only measure of gpu performance. The Xbox one gpu has double the bandwidth of a 7770. So please stop calling it a 7770. Please

Please I think this is the first time I see a clear and and comprehensible summary about the differences between a off-the-shelf GPU AMD 7770 and the Xbox SOC GPU as we know it so far. I agree with shredenvain on this, we cannot compare the GPUs of Xbox One and even PS4 with buyable products for a PC. Excellent post!  P.S. No need to getting tired of people ... we all have different backgrounds and experiences, thats the reason we discuss the things on a forum  |

I thought it was 7850, wasn't it as per digital foundry?
and 7790 as per extremetech

The X1 Gpu is closer to a HD7790. They share the same Gcn 1.1 arch. The 7790 has 14 active compute units compared to 12 in the X1. One difference is in the compute command processors, Ms has completely customised the command processors in the X1. The 7790 doesnt the extra DMA processors(Move Engines) or the same custom scaler with 3 display planes. X1 has the Shape audio chip onboard where the 7790
has the amd true audio(only active in the r9
version). There are still differences in the X1 gpu that we dont know about if semiaccurate is to be believed also true if the X1 is fully Dx12 compatible. Still as close as the X1 gpu is to a hd7790 the X1 will well out perform the
7790 because of the Esram and closed box advantage. I am hoping that we will eventually here the other parts of the gpu that ms have customized. Maybe we will when all the details are revealed about Dx12.

Unfortunately I doubt that MS will share this information with us. If we look on it from a business perspective companies don't tend to share their IP assets with the public to protect their own business. |

Some questions about xb1 an ps4
about ps4
How many command processors does it have? I've read 3 different sources saying 3 different things
First say Just one that handles both compute and graphics
Second says 3 2 Graphics and 1 compute while 1 of the graphics command processors is reserved for the system
Third says 4 just like xone, but one gcp is reserved for systemt
About xbox one
Did we ever find out how the system can get 6 cu's to run like 12? (Can this turn all 12 cu into 24?)
What are the special chips inside the cpu to help with calculations?
Does anyone have any clue as to what the other 35 mcu do?

I can only answer few of your questions and only about Xbox One. As we know so far the GPU of Xbox One consists of 12 CUs that are active. It was said in the Eurogamer.net interview that there a additional 2 CUs that are not active for redundancy purposes (has to do with possible errors in chip production so with redundancy you get a better yield). The special processing units are used for several offloading capabilities. You should look onto the slides that were presented at Hotchips to see what there purpose is (Audio, Move Engines, ...) Hotchip SlidesHope this helps!! |

Just another thought after I have answered to you the first time above... Are you collecting arguments for your buying decision for a next-gen console? If yes then I recommend not to base that decision only on technical paper sheets but foremost on the games you want to play and the features you want to have in the console. Of course the technical specs should come into the mix too but if we are into the current generation a little bit longer the differences in performance will disappear as it was the generation before. Hope this helps too! |

I know about all the hotchip stuff, but what I want to know about is the stuff milky's insider talked about, and I remember someone from MS saying they added something to the cpu to help with calculations. I already own an xbox one, just trying to find out more about it. |

I already own an xbox one, just trying to find out more about it. Good things come to those who wait Microsoft still has to disclose many informations regarding the hardware and architecture (if they ever choose to). Lately GPU double thread capabilities have been hinted by insiders and I believe DX12 will have a big impact on the architectural usage of the X1. For the SPP and/or the 50 MCUs I have been asking the same question in an other thread: xboxgaf.boards.net/thread/317/purpose-50-mcus-15-sppsThey will fullfill some offloading tasks and Microsoft confirmed audio and the move engines. The rest was mentioned as parallel engines of which some are more like DSP and others like CPU cores. We have to wait untill MS tells us more. In the other thread I speculated about some kind of "Samsung Reconfigurable Processor" as I found in the linked paper. But that is just speculative thinking from my part. But I could imagine some MCUs working in that kind of manner within the X1... |
