| Adinnieken said: What I think is interesting to note is that the PS3 had only 20% of the memory bandwidth that the Xbox 360 had, yet it was still able to offer similar levels of game quality to the Xbox 360. Yet there are people who want to doom and gloom about the supposed significant difference of the Xbox One's bandwidth to the PS4's. With the Xbox One and PS4 we're talking about an even smaller relative percentage difference in bandwidth.

Is that adding things up again?
Xbox 360 512Mb GDDR3 bandwidth is 22.4Gb/s
Xbox 360 10Mb EDRAM is 256Gb/s
PS3 256Mb XDR main RAM 25.6Gb/s (3.2Ghz)
PS3 256Mb GDDR3 vRAM 22.4Gb/s (700Mhz)
vs
XBox One 8Gb DDR3 68 Gb/s
XBox One 32 ESRAM 102 Gb/s
PS4 8Gb GDDR5 176 Gb/s
The unified memory pool together with the blazing fast EDRAM buffer did give 360 an advantage in framerate stability.
This time the xbox one's 'fast' ram is slower then it was on 360 and the entire ps4's memory pool is faster then both. Plus the Xbox 1 still has to make an extra step to fill the 'fast' memory.
We could do something as equally rediculous as adding bandwidth up together, let's look at a weighted average by memory size
360 : ps3 = 26.8 : 24
xb1 : ps4 = 68.1 : 176
We're talking about a much larger relative percentage this time.
