I think that means it will have all the features that DX 11.1+ has... PS4 won't use Direct X as that is Microsoft's. It'll be OpenGL.
Yeah, doesn't make any sense. They balanced the rest of the hardware for 14 CU's, but put in 18 anyway. !?!?!Any idea what that means?
Pfft, i can't see anything new there, unless i'm missing something.
Dual-camera maybe? Ugh, don't copy Kinect, Sony. Please.
The Radeon HD 7850 has 64 Texture Units. This article says GPU in Orbis has 18. That is a huge 3.56 times less than the stock card. Are they correct about this?
Yeah, doesn't make any sense. They optimized the rest of the hardware for 14, but put in 18 anyway. !?!?!
Or maybe it means 4 CU's are disabled for yields.

Sony has had a Camera since the PS2, how the fuck are they "copying" that Kinect when kinect is copying them?
PS2 classics are PS2 games. They do not depend on PS3 BC, rather on Sony's ability to create a PS2 emulator for PS4.
They already have 2 disabled.. the original GPU features 20, not 18.
Could you compile new PS2 games to run on a PS4 using software? Sure. But then the 70-100 (I'm not going to count them, this is an estimate) games already on the service will not work on the ps4, and you'd have to re-port them on the new emulator.
No, Ps2 classics are PS2 games compiled to run on a PS3 using a software emulator designed for a PS3.
you can't just dump them as-is on a machine that isn't compatible with the PS3 architecture (say, the ps4, or the 720) and expect them to run.

This is not only extra work for Sony (who does the port job themselves), but also once again splits the store into PS2 classics that work on PS4, and PS2 classics that don't. Users that bought Maximo to play on their PS3 will have to buy it again, or Sony will have to work out a way to give them free copies- essentially doing the port work for no financial gain.
So- is it possible? sure. Does it make sense to do it this way? not really- the amount of work it would take to keep PSN consistent without including some kind of BC would outstrip the cost of a 30 dollar part.
If it is emulation, you don't port anything. You may have emulator profiles and of course only certain games may be ale to run in the emulator due to the lack of eDRAM. As far as I have read the PS2 classics are just ISO dumps. In theory PS2 emulation would be much easier in the PS4 (no bandwidth issues), so you could have full BC with disc or DD with little work, the same way it works with PS2 games in the PS3.
What did Sony do to get PSP games running on Vita? They made a new emulator right? For free on the users end. Same with PSone games on PS3 right? Is there still hardware in PS3's that's dedicated to BC?
I guess the question is is it possible for the PS4 to even run PS3 games in software emulation tech wise.
At the top end is the quad-core A10-6800K, which features a built in Radeon HD 8670D mobile GPU, and has a TDP of 100W. This is a 'K' part, which means that it will come with unlocked CPU multipliers and GPU stream to unlock extreme overclocking.
"Richland" APUs are based on an updated Trinity architecture, and are built using the same 32-nanometer process and Piledriver CPU architecture. However, they differ from Trinity parts by having higher clock speeds, featuring updated Radeon HD 8000 series GPUs, and faster DDR3-2133MHz dual-channel memory controllers.
But only 18 Texture Units? That can't be right. That's less than the Radeon HD 6570.
Shame there was no mention of that BC chip in these new leaks. I think sony would be in a bad light if the next xbox is fully backwards compatible with all 360 games. All that content for the durango at launch. Microsoft did previously state that the next xbox would be fully BC even.
Why are people dismissing this info? Because here on GAF there were similar sentiments?
IIRC, many here had "sources" of their own which echoed these leaks. Is it hard to believe VGLeaks' sources also had the same info and are all basically concluding at the same source?
It's not hard to believe imo...

Well there are questionable informations, and some make little sense. Even the graphic looks amateurish and simplistic: "8x jaguar cores X86-64 CPU Cores".
Also it does not give any new infos, it seems based on what we knew already. So yeah, i'd call this dubious, although they probably get the basis correct, because they were known.
Yeah that plus the CUs number, the TFLOP that doesn't not seem to match it, the wrong BD speed, the lack of texture units...The only questionable thing here is that the claim is that it's including a dual camera, an "evolved" dualshock (I'm guessing this is the touchpad based one) AND a move controller.
That seems like a lot, personally.
Question for those in the know... 18 Compute Units but is Hardware balanced at 14 Compute Units. Does that affect the real life performance of the theoretical max 1.843 Tflops? Or is the 1.843 Tflops already taking this into account?
the 1.843 is based on 18CUs, but nobody seems to know what the 14CU thing is talking about exactly

They aren't. ISO dumps won't work because the PS3 isn't powerful enough to emulate the PS2 entirely in software. The PS1 classics are, though.
Yes they are. If you have any evidence fo the contrary feel free to present it.
PS3 is powerful enough to emulate ps2 games, just not the whole library. Who would be recompiling these niche as hell ps2 games? And how could you recompile a ps2 game for ps3 while keeping the same exact video output settings as the original console? You'd have to do more work to prevent improvements. Hence, these aren't ports. They are ps2 ISO files. They work as such. They are listed as such.
don't they use ps3 saves though? so something slightly different must be going on
the ps1 classics just use the virtual ps1 memory cards on the system(thus you can use your old saves)
ps2 games did the same on the 60gb ps3
It's in a wrapper. It's like WINE. It's not fully recompiled, it's not emulated either.They don't use ps3 saves. A new custom ps2 save folder is created. I don't know why they did that, but maybe it's more convenient than creating and managing virtual memory cards. Original ps2 saves can't be transferred.
Possibly 4 CUs are used for physics and 14 for GPU. If it's a 8000 series there is no 2014 context switching and graphics pre-emption to allow fast switching between OpenCL use and GPU use. A Temesh APU was a 2 CU GPU and 2 jaguar packages. AMD recommends APU + GPU till 2014 but if it's going to be one GPU there needs to be separate CU for physics.Split between the GPU and the additional compute unit: 14 and 4. Not sure why Sony has decided to split four off though.

edit: unless i was misinformed. i havent actualyl played any "ps2 classics" yet, but someone had told me ps2 saves weren't compatible with them. if that was true, well shit. this is great news
The reason the disc version isn't playable on the non-BC PS3 is because Sony won't allow any PS2 disc to be run, the emulator is only for PSN downloads. Again, it doesn't have anything to do with whether they are emulated, in a wrapper, or recompiled.It's in a wrapper. It's like WINE. It's not fully recompiled, it's not emulated either.
This is why the "PS2 Classics" download of God Hand is playable in a non-60GB PS3 but the disc version isn't.

So what is the mysterious Compute Module that Eurogamer article mentioned?

Disappointing. Maybe they went cheap so they can include the cameras and move controller.
Nope.
Durango= secret sauce
Orbis= special sauce, maybe as a reaction to the use of using secret sauce in earlier Durango talk
