What a surprise, another poster who refused to believe the facts, is no where to be seen, (A few others have disappeared the last few weeks)....Not sure why people try to refult clear cut technical fact.

eSRAM is being used as VRAM in Xbox One like eDRAM is used as VRAM in Xbox 360 like eDRAM is used in Wii U as VRAM and like GDDR5 being used as VRAM but also as system RAM in PlayStation 4.

If developers knew to use eSRAM then they would not have problems using it at all, eSRAM is as tricky as eDRAM and did you forgot what Cerny said about eDRAM/eSRAM? You can get more out of it in the long run. http://www.youtube.com/watch?v=EYeArDcfOJU&t=38m54s

176GB/s while Microsoft said that Xbox One has over 200GB/s of bandwidth for GPU thus less bottleneck while DDR3 is better for operating system because of latency. Xbox One has DDR3 at 2133Mhz and that is high end even for a PC also as Cerny said, eDRAM/eSRAM is easier to manufacture and is faster yet it is harder to use its potential.

Both Microsofts and Sony's aproach have its cons and pros, Microsoft's in the long run can have an advantage.

The higher the bandwidth the higher efficiency and utilization of GPU is possible in the long run.

Since PS4 has unified pool of GDDR5 thus it will sooner or later empty those GDDR5 chips used by GPU while DDR3 RAM in Xbox One can be used as regular RAM and just store data and does not need to really empty its self quickly

They don't have problems with it. The problem is the GPU and the fact that esram is so little. Surely the situation will improve but because of the improved SDK's, not because of learning esram. What do you think they are doing with it, let it sit there? The 200 GB's of bandwidth is not even lolworthy. The latency thing is a complete misinformation. Try to stay up to date.

Sure they have pros and cons. PS4 has hardly any cons compared to Xbone though. This is a fact, no matter how hard you try to spin it. Take it easy, if you try this hard a few years later you'll be in the Nsanity's situation. It is not pretty.

?? WTF??? Please explan how DDR3 does not need to "EMPTY so quickly"? You make that up?? GDDR5 can hold stufff in memory as long as it needs....No amount of 32 MB of esram will help the x1..it';s too small. If anything ti hinders, it is just another obstacle for information to get where ot needs to go. Everything you said is nonsense.

Again, that wont help the x1's significantly weaker GPU..........

ddr3 is NOT better for latency...period.

There is no amount of SPIN changes the fact the x1 is a lot weaker then PS4....

There is not 1 technical article on the internet that says the x1 is even on par with PS4...it simpy is impossible.

I don't know why they try this hard. Microsoft tried a different approach. They didn't try to create the most powerful console (Though obviously they lied and they lied and they lied about it (if you want proof that's something I can provide)). If they say they like MS's approach, that is perfectly fine. Though they try to fight with cold hard facts, that is something I cannot understand at all. It is also getting tiresome (and still pretty damn funny at the same time).

i knew about for a few days now you can see the wall post on his profile i didnt and know one really shouldnt make a thread about his departure b/c what if maybe he left b/c of something else like personl promblems health or a death in family im pretty sure if a thread was made sony fans would be bashing him and if he left here b/c of the reasons i stated, thats not right

in his defense the quote in his wall is actaully his from around june so his lost of intrest in gaming dates back

Again I must repeat myself:

1. esram is ABSOLUTELY NOT used like edram on 360 and IT IS NOT VRAM. Read my previous post.

2. Again read my previous post. NOBODY has yet figured out the >200GB/s voodoo number ms pr has promoted. The truth currently stands at 109GB/s for quad line access between gpu and esram.

Micron's DDR3 PC2133 has a typical CL14 read latency specification but possibly set as low as CL11 on the Xbox One.

Hynix' GDDR5 (I don't know which brand GDDR5 the PS4 will use but they will all be more or less the same.) has a CL18 up to CL20 for GDDR5-5500.

Now with GDDR5 the data rates are 4x faster than the IO clock instead of 2x, I.E. 5500Mhz GDDR5 is 1.375ghz x4 and would have a CAS Latency of 18-20.
18/(1.375 GHz) = 13 ns at a minimum.
Typically DDR3 has a latency of 10ns.
So one can assume the Playstation 4 has a latency that is 20-30% higher than the Xbox One.
We also cannot discount what effect the eSRAM has on latency as it is essentially a chunk of memory that's close to the GPU and CPU.

However with that in mind, there is a reason why CPU's have L1, L2 and L3 and sometimes L4 caches, it's to hide latency and bandwidth deficits by having to travel all the way down to system memory.
GPU's however really don't give a crap about memory latency and they also have L1 and L2 caches too.
So in the end one can summise that any potential latency deficit the Playstation 4 has isn't going to mean squat in the grand scheme of things.

And for gaming, which the Playstation 4 is designed for, Memory Bandwidth > Latency.

PS3 and 360 were a very different than XBO and PS4. Those systems were very close in GPU with 360 just edging out the PS3. On the CPU side PS3 had a sizable advantage, and it was that difference that allowed PS3 to eventually catch up. PS3 always had the raw power advantage of 360, but due to Cell's steep learing curve it was not seen until devs and Sony had better tools and knowledge. 

This time around both systems are neck and neck on the CPU side, but on the GPU side there is a massive gap. XBO ~7770 or R7 260 and PS4 ~7850 or R9 270. The PS4 GPU runs games at the same frame rate or high at 1080p than the XBO GPU does at 720p with the same game setting. Though the Power gap is only 50% in FLOPS the pixel out put is more or less 100%. 

Both systems have many modifications. XBO have the data move engines, and the ESRAM. The PS4 has the 8ACE/64queues only found on the top end R9 290, and HUMA. Over time developers will find ways to make each system perform much better, but at the end of the day XBO really has no chance of ever catching the PS4. 1080p/30fps on PS4 will always be 720p 30fps on XBO.

I love it when the biggest butthurt fanboys of a company are the higher up executives in that company. Its quite a speculate to behold lmao.
