No it's not the same as including only 3 cores, actually you when benchmarking CPUs on PC there is a set of benchmarks aimed at "cingle core" performance, this is easily measurable and the effects on modern game engines are well known.
For edram, esram, or any other type of buffer, even CPU and GPU L1 and L2 caches while we are at it, why not just ADD or multiply the bandwidth of all the busses into a single big number? because a 32MB buffer, even if it is almost as fast as the complete 8GB GDDR 5 the PS4 has does not make the xb1's 8GB of DDR3 as fast as the superior solution, at best in some very specific circumstances it may come close, on average probably not so much, but it will need to be flushed and refilled every few milisecond... this is not a problem if you only 1 bank of very fast memory.
So in the end, in some cases if will make things a lot faster than if the gpu only had the DDR 3 RAM, in other cases it will barely make a difference, so you can't just add it up like that and compare them, they're not the same thing.
So what's the number you would put for the xb1, xbox 360 and Wii U? because they all have that sort of setup.
