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.

The eSRAM isn't a limitation. Developers don't have to use it, they have a choice.
If developers make use of it, they get a performance boost, how could that be described as a limitation when it increases performance?
Is it as Ideal as the memory set-up in the Playstation 4? Heck no. But it's still not a limitation.
Fact of the matter is both systems are going to have games that look downright fantastic, eSRAM or not. (Granted at only HD resolutions. Ugh.)
In the end, most games won't be any different across platforms, save for some minor details (That people will most certainly blow out of proportion), most developers use 3rd party game engines and don't optimise for any specific platform to a massive degree, it's only the first party developers who generally push the envelope.
But if you are indeed worried about graphics and performance, get a PC and stop stressing.

Of course its a limitation. There is only 32MB of it and its there to improve memory bandwidth. If developers didn't use it the Xbox one would be even slower. Why do I even have to explain something so incredibly obvious. There is 8GB of low bandwidth memory and 32MB of higher bandwidth memory in the Xbox One. The PS4 has 8GB of very high bandwidth memory without restriction. The PS4's 18 gpu compute units and 8 cpu cores can all access memory without restriction at the full bandwidth. The xbox one has about a third of the bandwidth but this additional 32MB of ESRAM allows some high priority tasks to work at a higher memory bandwidth. 32MB isn't even enough for a 4K frame buffer so not much future capacity.
The performance level of the PS4 is significantly higher than Xbox One. Perhaps something like the ratio between the original xbox over the ps2. While ps2 and original xbox ran many similar games the original xbox versions were often enhanced, higher resolution, better sound, more graphic detail, better frame rates.
While the ps2 simply wasn't capable of many of the original xbox games like Half Life 2 the same probably isn't true here. I think the issue here is while both can probably run all the same games due to similar cpu and memory resources the PS4 will hold a significant graphic advantage, higher frame rates, higher resolution and enhanced graphic detail.
None of this will stop me enjoying Xbox One games but I'm certainly not interested in buying an Xbox One at current pricing.
