Your are not making any sense…. why are you dividing the equation of the BW by the size of the eSram? It makes no sense…. the eSram at the size of 32MB has the output real world bandwidth of 150GBs. I think a big issue is that the gaming media hasn’t properly educated the community.. You keep trying to make 32MBs of eSram a limitation like it can only push 32MBs of data in some cases. What you fail to grasp is the difference between physical size and data. When they say 8GBs of Gddr5 ram moves 178GB/s that is it there is nothing else to calculate same thing with 32MBs of eSram having real world performance of 150GB/s that is it 32MBs of eSram = 150GB/s.
Your crazy equation up their using those numbers could only tell us how many GBs of data a divided MB of eSram could move…… its almost a pointless numbers.
And to your question of why would you want static memory…… here is an example for you.
Imagine a building in a game the building is 3d you can go inside and around and needs to be textured so the walls look like bricks and the floors look like marble. In the Ps4 and pretty much PC (the standard way). The GPU has to go to the gddr5 ram get the texture and draw it every cycle. It basically reads and writes the data every cycle that that texture is needed. This is because dynamic ram has to be refilled and refreshed
On the X1 that texture is written to the eSram once and the GPU just keeps reading that same texture over and over until the scene changes and that texture is no longer needed then another one is loaded in.
The basic idea would be what more efficient if you had to constantly put your name on a million documents. Ps4 would be a quill and ink the X1 would be a stamp.
Physics is a CPU activity eSram is connected directly to the GPU for a reason. Its a super fast pipeline for reading and writing from the GPU.

Optimization, it’s not easy to change an engine to run everything through esram, devs are used to throwing chunks of memory through gddr5

Errrm he did say 150gb/s for esram…

This was mostly about reading from system memory (I should not have added a single read from eSRAM)

But lets do it your way – how many times do you actually read all those 32 MB of the eSRAM between frames?

60Hz: 150 GB / 60 Hz / 32 MB = 78 times
30Hz: 150 GB / 30 Hz / 32 MB = 156 times
(rinse back and forth between your teeth…)

You need to use a rendering algorithm that requires a lot of intermediate store/read using the full eSRAM (and that not can make use of the GPU internal even faster buffers…)

If the algorithm uses less than 32 MB you need proportionally more times.

If the algorithm on the other hand needs more than 32 MB, bad luck you have to hit SDRAM…

And no, you can not fill the eSRAM from SDRAM without penalty.

Keeping static data in the eSRAM (as you hinted on in another thread) why would you want to read that more than one time? Lets see…

* Physics simulation of world objects run at higher than frame rate?
(this easily ends up bigger than 32 MB, guess why MS thinks cloud)

Someday, someone will find out how to really use XBox Ones complex (I refuse to call it advanced) memory system. But having a program managed SRAM isn’t really anything new… (But motivation has probably grown among companies, professors and students)

?? What is your point.

You do realize your comment actually supports what I said right. Your reading comprehension and math skills are atrocious.
Nick Bakers comment basically states that eSram has a real world usage of 150GBs….. Like I said. I could explain this to you in more detail but you didn’t even see your comment actually validates me and you attacked me with it…. So you have no clue of whats going on.
I don’t feel like talking to a Guest…. be a real person and make an account and stand by your comments.

Although not confirmed. Xbox is apparently opening the 7th core completely with new OS.

2 reasons… why the X1 has lower resolutions sometimes.

The first reason is….. because you have a small penis and cant satisfy women.

The second reason is because the X1 has a more complex and advanced memory system. the bandwidth is there its just a matter of laying the assets out correctly.

Correction:

Ps4 game os: 6 cores 5.5gb ram
Xbone game os: 6+up to 70% of a 7th core, 5gb ram

Mmm, I hate to break it to you but you obviously don’t understand the way the flexible memory works. It 4.5GB of “Direct Memory” which is allocated in the traditional way and then an additional 1GB of “Flexible memory” which is 512MB of the GDDR5 RAm and 512MB of HDD space which is managed by the FreeBSD OS which has some very nice FreeBSD virtual memory functionality. So in other words, 5GBs plus another 512MB of HDD space. So the same and better than the X1. And the 7th core on the X1 is only “up to” 70% and can be taken back by the OS at any time its needed, hence highly unreliable and most devs will stay away from. And the PCars devs already used the 7th core on the X1 for sounds and the game still has 44% lower res and a worst framerate. So, so much for that sh’t helping.

Face it, the X1 is inferior anyway you cut it. Hence why everybody else prefers a PS4 except for you diehard MS fanboy idiots. Keep being stupid and we’ll keep laughing at you.
