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.

Did you just add the bandwidth together for each consoles RAM? Considering your earlier posts, surely you know better than this?

The memory bandwidth is fairly similar in the PS3 & 360 (around 22-24Gb/s). The 10mb eDRAM does have a high bandwidth of 256Gb/s, but was only useful for a small subset of tasks so is not all that useful for comparison. Then there's the different memory architecture which makes direct comparisons problematic.

360's EDRAM was connected to the GPU by a 32gb/s bus, so while it operated internally at 256gb/s, that wasn't the "full" bandwidth it actually had.
