DF: Orbis vs Durango Spec Analysis

Member
So... Durango has a 100 GFLOPS audio DSP that Orbis will need to use up to 2 CUs (which would, afaia, amount to up to 200 GFLOPS of compute performance) and other dedicated audio hardware to match?

I don't know the numbers, it could be 1/2 of a CU to 2 CUs.

2CUs would be overkill, maybe PD would do something like that for GT6.
 
I hope Sony confirms no BC for PS4 on the 20th,would be interesting to see if MS does it.
While it's not Cell, presumably emulating Xenon and Xenos on an x86 CPU and AMD GPU aren't trivial. Are we expecting BC on Durango?

Sony's solution appears to be streaming.

Aren't Sony historically monsters with sound in electronics? Would they not have seen the same audio processing issue MS did in this generation and put a chip on to deal with it accordingly?
 
Well, not to dismiss your case, but Durango has an audio chip that needs 100 gflops of CPU power to emulate. Otherwise your comparison is sound but amateurish.

Devs should begin talking around E3 time and afterwards, we'll get a better sense then of the real world comparison.

Y2KEV Are you writing this shit down in your notebook of reckoning for later? After your earlier post?

It could also be 0 CUs. Why are we assuming that the PS4's DSP can not process 7.1 digital surround sound and that the GPU (!) has to help, when it would be much easier to just use a slightly better DSP (costs probably negligible). This just seems like a new, silly attempt of damage control, sorry.

Sony's CTO mentioned a DSP and additional programmable logic when referring to the PS4's hardware.

Yes, not a single console they've released had problems or "lacked" in sound. PS3 supported every sound protocol out there, including 7.1 LCPM. The cell was very capable of processing that.

What about Orbis' Audio Processor (ACP)? It also has one built in. Surely that plays a similar role to Durango's audio chip?

I hope with the current popularity of gaming headsets, that someone will bring back HRTF. Because that was freaking amazing 12 years ago when Aureal sound cards did it, and it's sad that the audio industry still hasn't managed to bring that back at a consumer level as far as I'm aware.

Strange that more Durango leaks are starting to spill out before the PS4 reveal.

Almost intentional.

Well....as far as I can tell, these "leaks" are from Microsoft employee's lol (Proelite anyway). Not sure if that changes how accurate the claims/leaks are mind.

I do find it strange that Orbis' audio chip is completely overlooked though, even though it is there directly in the leaked specs. Either Microsoft has an audio chip that is vastly different, or the same thing in Orbis has just been overlooked. Conveniently...
 
I'm going to summarize what I know with regards to Xbox 3.

VGLeaks info has been accurate due to what the info is coming from.

- Always online/internet connection required
- No used games
- No BC
- CPU has increased performance over normal Jaguar cores.
- ~3GB and 2 CPU cores are reserved for the OS, apps, Kinect, etc.
- Xbox has a crazy (IMO) amount of hardware dedicated to audio tasks (e.g. gaming and Siri capabilities)
- Kinect is a pack in
- Same day digital releases for all games

If I learn anything new before I leave the boards, I'll pass it along.

For me I'm not going to write off Sony's audio direction at this point. With the change to Jaguar cores, they will need something competent in that area.

So, Proelite, you want to retort point by point?

What do they need all this power for in an audio chip?

Well some titles, especially racing games do a lot of audio simulation. Forza 4 I think used up an entire 360 core just to process audio. According to bkilian, he said that we should not underestimate the cost of audio in games, for example he said that a request by a certain dev wanting to do some audio processing in a game he was working on, the entire flops or power of the 360 would not be enough to process it, so a really powerful dedicated audio processor to be able to move to better audio effects in games.

What is this supposed to imply exactly? That some of these things, perhaps in lesser form, were also apparent in the early alpha kits? How does that justify the omission of regarding Orbis' audio chip?


EDIT: Googling some more, it seems one of Cell's SPU's (not SPE's) can decode around 400 MP3 streams using it's multistream functionality, so stack up the early figure of 200 MP3 streams concurrently on the Orbis alpha kit Audio Processor how you will.

Man I hope youre wrong about the 720 stuff. I really hope Sony doesnt follow suit with always online/no used games crap. Wednesday cant come soon enough.

These were target specs. Despite being old they should still hold some useful information that were missing from the newer leaks.
 
Audio proccessing unit sounds like it could be anything. I'm pretty confident that they would be able to at least support any format that the ps3 could which is fine.

All of this (minus the dd releases and cpu power) had better be wrong...
Jeez, talk about lowering the bar.

If they even talk about something like that on Wednesday to begin with. That seems like something we'd learn away from a presentation like that.

So if only Microsoft does this, wouldn't they be digging their own grave?

Depends. If they have the support of publishers they might get something in return. Like timed exclusives CoD, GTA or AC. Just read some publisher statements about used games in the past and you know who will support the closed platform.

Well I would think that if they arent following MS strategy they would want everyone to know asap for some good PR. Then again I guess those decisions could potentially change all the way up to launch so who knows.

I don't really care much about BC, but the no used games/always online stuff sucks. I hope digital titles are cheaper than physical copies.
