That is a pretty dramatic difference in texture size. Hopefully it's actually practical to implement. Are there any games that use this technique, today?

yea.. certainly seems a bit too good to be true.  obviously this "feature" wasn't utilized for BF4 or Ghosts...

While it's not used yet I expect it to be, the whole reason MS has those custom move engines in the XB1s SoC is for them to move data from the DDR3 into eSRAM and so on.   The setup of the hardware seems tailor made to use these techniques in hardware but developers need time to work it all out.   Right now, as was the case early on with the 360s eDRAM, I'm sure they're just using it for basic AA in games.   I expect the 2nd batch of games we'll see later in 2014 to use it.

This feature is still in the development fase and I doubt it would have made a difference to boost resolution at this point for the launch games of the Xbox One. We'll see what the future brings though.

 

Looks like going to 1080p on PS4 isn't paying off as numerous reviewers have pointed to large framedrops on the PS4 version of Call of Duty:Ghosts in both the campaign as well as the multiplayer.

 

I wanted to add the URL, but somehow can't (IE11?). Tthe article is on GamePur right now.

 

Thanks blerk!

That's because they're 3rd party developers..

People may not like Halo, but I GUARANTEE that, Halo 5 will show almost everything the Xbox One can do in its early life cycle. Sure we have almost a year to wait for this, but if we all know Microsoft, tons of $$$ & resources will be thrown at this to make sure their vision comes to life.

S*** they can like it or not, Halo was the reason Xbox got hot in the first place. I love Halo to death and I better be amazed by Halo 5, nevertheless the TV Series.

lol... true that... true that...

 

You already know 343 got a blank check and was told to "Go H.A.M."

Agreed. I personally believe "Halo" (as its currently marketed) aka Halo 5 will be the most heavily marketed game of the series (& likely any 1st party title from MS) since the original Xbox came around, if not ever. Reasons include the push for the console as it begins forming a decently sized community, will have been out for... a year or so(?) and the beginning of the franchise on the new tech (in addition to 343 getting whatever resources they need to show off the Xbox One's power). Let's not forget the likely spin-off web series, mountain dew/Doritos type marketing, and then good ol' tv commercials. Halo movie? or was that a different MS title, I can't remember. Either way, I truly believe MS will fund whatever 343 requires and will market harder than they do for any hardware they have out (surface, phone, etc).

 

Let's just pray the single player is great and the multiplayer is even better so there isn't a massive drop off of community & players like Halo 4 experienced. Went from something like 70-90k to 15-20k in an incredibly short timeframe.

 

Edit: In my opinion it really speaks volumes to the importance Halo has to Microsoft by not rushing Halo to be a launch title for initial console sales, especially with claims of rushing the hardware a bit to keep pace with a PS4 holiday release. Hopefully this will shine through upon release.

Xbox One eSRAM + DirectX 11.2, where 32Mb = 6GB            <-------  If this is true, then...WOW!!!!  If not, Oh Well, I guess.....

 

That would make for a nice performance jump...  Are these numbers actual (real life tested, on Xbox One) or theoretical?....

Though that does explain MS not spending so much money after GDDR5 and sticking with DDR3 and not going the 699 price point.

 

GDDR3 has lower latency, which means they can pump through to the ESRAM faster, while GDDR5 has higher bandwidth... i don't think most people have any clue what they're talking about when they just assume one is faster than the other just because its 5vs3..

There's a video showing how it is utilized, to clarify it is in reference to texture quality and tech. involving how surfaces and their details are displayed, its not like your next AAA's install size will be smaller or anything like that. The link in OP does show screenshots and link to the video further explaining how developers can/will use the technology. The biggest bonus aside from freeing up resources and memory bandwidth is that rather than being used on a software level, meaning only by some, depending on their engine etc, it is handled at the hardware level - meaning anyone who develops games for the XB1 can take advantage of it if they so choose. Hopefully Microsoft will hold events to better educate devs on best practices etc to make this a relatively standard inclusion on future (post launch) games.

You know i dont get  why  review sites  like the one listed above for the  supposed issues regarding ghost  PS4 framerate issues   why they review so early when they know ther is  to be a day one patch for both systems that could  in all tenntse and purposes  improve  the performance of those games  and or maby the games themselves have a day one update  to go along with the console updates

I've got to add some context to this because even though the 32mb 6gb statement is right in context you would never use eSRAM for texture filling with tiled textures because it defies the point of fast ram. Why would you waste 32mb of RAM which in real-time application runs at 140 something Gbs when you're writing 16mb to it every couple of seconds when the FOV changes on an object? It's a situation what DDR is perfectly suited for. Tiling textures is designed around DDR because DDR is perfect for quick returns on smaller read/writes. For example 16mb chunks of textures. 

 

eSRAM is perfect for frame-buffering and post-processing because you will literally be reading and writing to the RAM pretty much constantly when your applying post-processing and filling. Dropping and filling the ram all the time.

Only 6Gb? I thought that now that the console comes with a browser you could download more ram through it!
