This is not from sony it's a blog that has been disproven months ago. The math dpoesn;t even make sense, try harder. I ask again, what does this have to do with Ps4 still be quite a bit more powerfull??? Thise doesn;t change that.


its not the onl site you know

Inside the PlayStation 4 With Mark Cerny

By Christian Nutt

The PlayStation 4 is due out this fall, and its technical specifications have been largely under wraps -- till now. While the company gave a presentation at GDC, the system's lead architect, Mark Cerny, hasn't talked publicly in any great depth about the platform since its unveiling this February.

Cerny approached Gamasutra in the hope of delivering a "no holds barred PlayStation 4 hardware expose," he said, during the interview that resulted in this story. "That certainly is what we're here to do," said Cerny, before speaking to Gamasutra for well over an hour.

What follows is a total breakdown of the hardware from a developer's perspective: the chips on the board, and what they're capable of.

Questions on the UI and OS were off the table. What was up for discussion is what the system is capable of, and the thinking that lead Cerny and his team to make the decisions they made about the components they chose and how they function together.

To get to the heart of this deeply technical discussion, Gamasutra was assisted by someone with an intimate knowledge of how console hardware really works: Mark DeLoura, THQ's former VP of tech and now senior adviser for digital media at the White House Office of Science and Technology Policy.

 

What Does 'Supercharged' Mean, Anyway?

"One thing we could have done is drop it down to 128-bit bus, which would drop the bandwidth to 88 gigabytes per second, and then have eDRAM on chip to bring the performance back up again," said Cerny. While that solution initially looked appealing to the team due to its ease of manufacturability, it was abandoned thanks to the complexity it would add for developers. "We did not want to create some kind of puzzle that the development community would have to solve in order to create their games. And so we stayed true to the philosophy of unified memory."

In fact, said Cerny, when he toured development studios asking what they wanted from the PlayStation 4, the "largest piece of feedback that we got is they wanted unified memory."

"I think you can appreciate how large our commitment to having a developer friendly architecture is in light of the fact that we could have made hardware with as much as a terabyte [Editor's note: 1000 gigabytes] of bandwidth to a small internal RAM, and still did not adopt that strategy," said Cerny. "I think that really shows our thinking the most clearly

dont know who the guy is?

On February 20, 2013 at the global Sony PlayStation 4 unveiling event in New York City Mark Cerny was revealed as the console's lead architect. He also showed in-game footage of his own new game called Knack which he is developing for the console.[9] On September 21, 2013 Cerny was revealed to have been the lead architect of PlayStation Vita.[10]

Yeah and nowhere does he sat 32 Mb of esram at 1000 GB per second will give you a major system bump overall. The 32 MB of edram or esram coulf be 100000 GB/Per second its so tiny it still has to go through main ram..Do you even know how ram and system work? Nowhere does he say any system has it, just that they could have, try harder.

 

No where also does it say the X1 has 1000 GBs of bandwidth...

 

Also, I ask again. how does this hel the video card?


esram and edram are simililar but different

i am aware that micrso said that the esram has 200gb/s, but doesnt mean that is comparable to an edram of 200gb/s since esram has adventages like no refreshment and less latency, so in the end could behave like an edram of 500GB/s for example

 

and dont forget this

The easiest way that I can explain this is that when you take each unit of time that the Wii U eDRAM can do work with separate tasks as compared to the 1 Gigabyte of slower RAM, the amount of actual Megabytes of RAM that exist during the same time frame is superior with the eDRAM, regardless of the fact that the size and number applied makes the 1 Gigabyte of DDR3 RAM seem larger. These are units of both time and space. Fast eDRAM that can be used at a speed more useful to the CPU and GPU have certain advantages, that when exploited, give the console great gains in performance.

The eDRAM of the Wii U is embedded right onto the chip logic, which for most intent and purposes negates the classic In/Out bottleneck that developers have faced in the past as well. Reading and writing directly in regard to all of the chips on the Multi Chip Module as instructed.

the edram is mainly for the gpu, not cpu and the os runs on the main ram not the esram, and considering how tiny the internal caches are like the local data, global data and texture caches then 32 megabytes dont look that tiny
