That's talking about all the memory in the APU: 47MB = CPU cache + GPU cache + eSRAM + some other minor stuff.

eSRAM is 32MB.

Yes. And it fits a 1080p image.

All the other cache should be used to the other tasks and stuff.

It all depends on the developer. Not to MS virtually increase this size.

Yeah, the hardware obviously is not changing. It's an API update. In essence, it is doing more with what you have.

The same sort of updates are being (or have been) made for PS4's proprietary OpenGL-based API.

I red something a few days ago about something comming along for PS4 called P2RLA but the guy who launched this acronym told me that he was not allowed to talk about it. We'll see if it's something to follow.

Depending on how many byte per pixel. Infamous SS uses 40 bytes per pixel, for example (83MB).

I'm not at all an expert on these things. I see people saying 20 percent more efficient vs 20 percent more "powerful". What's the distinction?

Sorry for the bad analogy, but let's say you have a car with 230hp but now you did a bunch of mods (intake, catless exhaust, turbo, intercooler, etc) and now is makes 300hp. Congrats you just made it more powerful.

On the other hand you have a car that is 230hp but you don't see that power until 6500rpm and it drops off shortly after. But then you do some mods that don't affect the horsepower, but your power band starts earlier (maybe 3000-4000rpm) and doesn't taper/drop off as much. Well you might say that you are seeing greater efficiency.

Shitty analogy but maybe it makes sense.

There are many ways to achieve the same thing when you are developing something.

So in this case it's how you use it, not the size.

Edit: I didn't know about a web site not quoting properly. So, here is the quote:

During a livestreamed presentation at Build, Xbox One Team Partner Development Lead Frank Savage explained in detail how the much discussed ESRAM of the Xbox One works, also mentioning that it can help developer sreach the fabled 1080p resolution goal or a 60 frames per second resolution with their games:

ESRAM is dedicated RAM, it’s 32 megabytes, it sits right next to the GPU, in fact it’s on the other side of the GPU from the buses that talk to the rest of the system, so the GPU is the only thing that can see this memory.

And what it does is that it gives you very very high bandwidth output, and read capability from the GPU as well. This is useful because in a lot of cases, especially when we have as large content as we have today and five gigabytes that could potentially be touched to render something, anything that we can move to memory that has a bandwidth that’s on the order of 2 to 10 x faster than the regular system memory is gonna be a huge win.

So this is where you put things that you gonna read a lot like a shadow map, put things that you draw to a lot, like your back buffer… We have resource creation settings that allow you to put things into there, and don’t have to all reside in the ESRAM, there can be pieces of it that can reside in regular memory as well. So for example if I’m a racing game, and I know that the top third of my screen is usually sky and that sky doesn’t get touched very much, great, let’s leave that in regular memory, but with the fast memory down here we’re gonna draw the cars. This works practically for any D3D resource there is, buffers, textures of any flavors… There’s no CPU access here, because the CPU can’t see it, and it’s gotta get through the GPU to get to it, and we didn’t enable that.

So the last thing you have to do to get it all composited up is to get it copied over to main memory. That copy over to main memory is really fatst, and it doesn’t use any CPU or GPU time either, because we have DNA engines that actually do that for you in the console. This is how you get to 1080p, this is how you run at 60 frames per second… period, if you’re bottlenecked by graphics.

Maybe windows central is the one who misquoted Phil Spencer? Maybe that 20% GPU boost is true for both XBO and PC? Let's wait for more details before blaming Phil Spencer.

That 50% CPU boost is still bullshit though, even for PC.

Actually it's not bs.

But that level of performance is most likely only possible on aging CPUs and the lowest end parts just like it happened with the Mantle optimizations.
 
Wait til Cerny turns off the Parity Bit, designed to lull Microsoft into a false sense of security, thinking they've closed the gap then BAM!
 
I was reading this thread on my way back home before the title change and didn't post anything because I was really skeptical about the "initial statement" (misquote). It's really funny to read the first pages again after the title change.

He has a point though. If you can get all the Xbox one exclusives on PC, why would you need the console? I'd love to be able to play the games with my friends who have the Xbox one.

Cheaper, plug and go, less troublesome, etc... People give casuals way too much credit to make their own gaming PCs.

Some people prefer console over PC gaming, I have all platforms ( just don't have any Sony handled one though ) so it won't change anything for me, I just love how he saved the day with his bullshit... this dude is strong :p
 
So what was the liveblog of? Was it a presentation Spencer gave on stage or some kind of interview? Would love to know exactly what Spencer said because it seems kind of impossible to misinterpret.

I agree that most casuals won't. I don't think most casuals visit his site, as that doesn't seem to be his target audience. And I can honestly see people who game on PC forgoing the Xbox One if they can get exclusives on PC.
