We don't really know how clever this eSRAM stuff is, how much ground it makes up etc. so hard to jump to conclusions yet. On paper the PS4 has more out and out horsepower, but so did the PS3 & it didn't exactly effect the 360's popularity did it.
Good question and dunno... there's been some leaks but the only official statement from Microsoft so far has been in terms of GPU power X1 is "8 times more powerful than 360".come on then experts.....going on the GPU specs how does it compare with PC graphics? 7850 like rumoured?

check my post on the previous page. It is almost confirmed that the PS4 will be 50% faster than the xbox one unless the xbox guys do some serious overclocking.

Not clever enough, it might make up some of the memory bandwidth, hell lets say all, but that then doesnt even account for the GPU CU differences, something that wont even be bridged with overclocking. eSRAM requires managment to make it efficient as a GPU cache and unless MS write some very clever algorithms then it will be up to developers to ensure how they talk to the GPU takes account of this. I think thats the problem, like the Cell its gonna take some effort in working out how to do things...We don't really know how clever this eSRAM stuff is, how much ground it makes up etc. so hard to jump to conclusions yet.

Ugly shiny black dust magnet.
No they dont, Anandtech talk about the possibility of reducing the bandwidth differences but not that what theyve implemented has - can you link me to a MS source regards that though? As it appears the numbers theyve used is a sum that doesnt actually make sense...1) Microsoft (and supported by Anandtech) claim very similar memory bandwidth to Sony, as the eSRAM and DDR combined are very effective.
Anandtech said:According to their data, there’s roughly 50GB/s of bandwidth in each direction to the SoC’s embedded SRAM (102GB/s total bandwidth). The combination of the two plus the CPU-GPU connection at 30GB/s is how Microsoft arrives at its 200GB/s bandwidth figure, although in reality that’s not how any of this works. If it’s used as a cache, the embedded SRAM should significantly cut down on GPU memory bandwidth requests which will give the GPU much more bandwidth than the 256-bit DDR3-2133 memory interface would otherwise imply. Depending on how the eSRAM is managed, it’s very possible that the Xbox One could have comparable effective memory bandwidth to the PlayStation 4. If the eSRAM isn’t managed as a cache however, this all gets much more complicated.
No it doesnt, it uses eDRAM primarily to provide 'free AA', and as far as Im aware from what Ive read its not implemented like the eSRAM in the XO at all, here its used between GPU and main memory and not for post-processing...2) The Xbox 360 also had eSRAM so it's nothing new for developers to have to code for. There won't be any difficulty coding for it.

eSRAM is going to take lots of baby sitting by devs, moving stuff into and out of the fast RAM to get best performance, where's PS4 just has fast RAM.
The big difference between the current gen and the next gen is that the PS4 and Xbox One are both basically the same to program for, but just with the PS4 being a fair bit more powerful so you're going to see the PS4 pulling off better looking/performing games without any problem.
Thats not really how it works, the size isnt the big issue its more making sure its always full, that will need some programming and forethought. Theyve cut corners mainly to get Kinect in there as a standard peripheral and to avoid the PS3 launch price...It's only 32MB though, the GPU alone will have 1-2GB of textures which will have to be stored in (much slower) GDDR3... and they've sacrificed GPU capability considerably to accommodate the ESRAM. Even if (theoretically) Xbox One had equal memory bandwidth (unlikely) their GPU is far inferior.
Hmm, dunno - it sounds more likely they weren't confident of being able to get 8GB of DDR5 so went for a safer plan. If PS4 had have ended up limited to 2 or 4GB of DDR all other things may have balanced out.Thats not really how it works, the size isnt the big issue its more making sure its always full, that will need some programming and forethought.
