New Kinect-free edition unlocks memory bandwidth reserved for Microsoft's camera sensor

Given Microsoft Corp.'s (MSFT) supply struggles, sales struggles, and privacy concerns regarding the Xbox One's "Kinect" video and audio sensor, it's perhaps unsurprising that Microsoft decided to at last offer a cheaper ($399) SKU of its console without the sensor.  Now that decision has brought about an interesting twist -- Xbox One users who ditch the Kinect may be able to enjoy better graphics performance.
 
It turns out that Microsoft's always-on sensor reserves as much as 10 percent of its graphics hardware's memory bandwidth and processing resources for watching its user(s).  Comments a Microsoft spokesperson to Eurogamer:

Yes, the additional resources allow access to up to 10 per cent additional GPU performance.  We're committed to giving developers new tools and flexibility to make their Xbox One games even better by giving them the option to use the GPU reserve in whatever way is best for them and their games.

According to Eurogamer and The Verge, Microsoft will for the first time be allowing game developers to use these freed up resources to enable special "Kinect-free" enhanced graphics settings.  While that's good news for Xbox One gamers, it also adds an interesting extra nuance to an already heated debate.

Xbox One Kinect

Microsoft's Xbox One has trailed its rival Sony Corp.'s (TYO:6758) console after committing a number of missteps, including initially planning to use DRM to ban used games and threatening to make users' consoles unplayable offline.  While it later recanted on each of these controversial terms, the console has continued to struggle through a number of controversies.  To add insult to injury, Sony recently announced that its rival offering, the PlayStation 4 (PS4) was already profitable.
 
Nonetheless it has moved millions of units and isn't too far behind Sony's PS4 in lifetime sales.  Microsoft has remained very committed to its console, releasing a major update in April.
 
The future of the Xbox One should be elucidated at next week's 2014 E3 (Electronic Entertainment Expo), which is being held in Los Angeles, Calif.  Stephen Elop, the new executive vice president of Microsoft Devices (which makes the Xbox), is expected to present his vision for the future of the console along with new Xbox chief Phil Spencer at Microsoft's Monday, June 9 press event.

It is a PC api only*. The caveat to that is it's designed give developers of PC games the same level of access to the hardware as the console API's. Makes it a lot easier to port the games between the platforms. So "Mantle" is the PC version of what the consoles use. of course MS will not say what is used on the XBONE is Mantle because they're pushing Direct X. 12 is supposed to incorporate some of the things the console API/Mantle does.

An analogy would for this would be like some of the Mazda and Ford cars. Says Mazda but pull that dipstick, pop that starter off, or remove the engine cover and it has ford printed on it.

Either way it works out for PC gamers. Now you will not need insanely better hardware to run a slight bump in graphics performance. Ports should be less sloppy as well. hopefully

That further proves there is more performance to come from both systems from low level API enhancements.

For the X-Box One
Kinect Disable in some games = 10%
Low Lever API Enhancements = ? lets just say 10% conservative but if you look at mantle on AMD low end chips its more like 30%
Better multiprocessor distribution which Microsoft says will be huge. No single core holding it back. But again lets play conservative and say another 10%
Developers optimizing code to squeeze out every bit of performance maybe another 10%.

It all adds up.

Ill say this the next time a new console comes out Im going to wait a year before purchasing to let the game base build up and for developers and manufacture to work out the kinks. I suspect the next games consoles will need to do 4k video thats tough today to make it cost effective.

Yes...which I have pointed out all along.

The only difference is that I made it clear that nothing is happening to the *hardware* itself. All improvements will be made through software, and possibly firmware.

It's amazing how many people seem to lack basic reading comprehension.

It read as if you were implying they couldn't because of hardware limitations.

Text is often taken out of context. Sorry if that occurred in your message.

I'm not sure that you're going to "optimize" hardware once it's in the field already......but the developers can probably continue to write better code, and make use of stuff like AMD Mantle for example.

How, exactly, can one read my OP above and come to the conclusion that I'm saying that you *can't" optimize existing systems in the field by making better software and using things like Mantle?

...granted that that's *exactly* what I said.

As others have pointed out, disabling Kinect only frees up 10% more resources. This most certainly cannot truly translate into a 10% performance increase.

Also the scenario you're depicting is highly unrealistic. A 40%+ performance boost across the board from optimizations? I don't see this happening for either console.

Agree. But even the next gen consoles might have problems delivering acceptable framerates for 4k gaming (native).

I can forgive the current generation. After all, they started designing the performance parameters for these back in 2009-9'ish, when 4k wasn't even on anyone's radar.

Sony certainly did better out of the gate by having the extra performance on tap.

Microsoft XBONE hardware is certainly capable of doing 1080p but they need to fix a few bottlenecks that currently exist that shouldn't have which is why only certain titles do it today.

I still say both are an AMD chip generation early or should have gone discreet graphics because I think both consoles will start to show their age in 3 years. To me there is no excuse for not having 1080p 60FPS on day one with room to spare so developers don't have to determine sacrificed eye candy or something down the road. What you wind up with is the PC versions will have additional eye candy over the console versions. Its the same game and gameplay just one subjectively will look better.

"I still say both are an AMD chip generation early or should have gone discreet graphics because I think both consoles will start to show their age in 3 years."

It was a cost thing, but I agree. That would have been better, but with a console, you always have to place a flag in the ground at some point and say "here us where we are" and build it. There will always be faster stuff coming.

"Sony certainly did better out of the gate by having the extra performance on tap."

Can I just point out in a friendly non-aggressive way that you have attacked many people in the past that said that exact same thing , myself and Reclaimer included. I mean went off the rails over the same claim.

/brain explode...

Wow, so like, it's okay for you to say this. But when me or retro does, we "hate Microsoft".

Ugh, anyway, moving on...

Agree. However maybe one of the advantages of going with off-the-shelf PC parts is a MUCH faster refresh cycle. No longer will Sony and Microsoft spend billions and years and years coming up with custom console hardware solutions that also cause massive developer headaches.
