The major limitation of the xbox one really is that 32MB of ESRAM.

The 32Mb of eSRAM isn't a limitation. Developers don't have to use it at all.

The real limitation is the DDR3 and the lack of compute resources, but the same could be said for the Playstation 4 in comparison to the PC which will become evident in a few years.


Without the 32MB of ESRAM you have 12 gpu compute units and 8 cpu's all sharing the same pool of memory of low bandwidth DDR memory. The ESRAM is there to help solve that issue but there is only 32MB of it. It's a clear limitation. Cache memory is there to remove latency issues and help coordinate use of bandwidth but there is clearly an issue with the xbox one, cache can't create extra bandwidth.

Also remember both GPU's have compute functionality. So the extra power of the PS4 GPU can be utilised for additional compute power if necessary which again means for CPU intensive games it can have an advantage. Obviously if the GPU is used for this then actual GPU work has to be reduced but there may be games where the PS4 advantage is an improved physics engine or more characters on screen or improved AI.

The PS4 is just a much more powerful design and will be capable of greater things than xbox one.
