Xbox One vs PS4: ESRAM slower than GDDR5, It's Bottleneck"

[Cyborg13B]

You're all wrong. The problem is the way the 32 MB of ESRAM is implemented. The amateur technologicians at ATi and Microsoft, instead of including it as a 200 GB/s Frame/Z-Buffer, included it as a 32 MB L2 cache for the GPU - thus giving the Xbox 3 basically 100 GB/s of memory bandwidth.
