Wait what? Why would they design a console to be weaker just because of kinect? Kinect was already calculated within the price so its cost would've never affected the console specs.

If they would've used cheaper hardware X1 without Kinect would currently be below 399. What makes the inferior hardare so expensive is the ESRAM. That was the idiotic decision that broke X1's specs. Not the RAM or Kinect.

Nah the eSRAM is necessary because of the RAM decision.  DDR3 alone is way too slow.

In turn the eSRAM takes up a lot of die area, and the Xbox One has 6 less graphic cores (Compute Units), fewer texture units & ROPs because of that.

 

If they decided against the ESRAM and put in the same number of CUs the difference would've only been in the single digits due to the slower RAM.

The ESRAM isn't even close in making up the power difference lost due to the missing CUs.

Ofcourse ESRAM can't make up for performance of the lost CUs, but if they had 18 CUs with no ESRAM & DDR3 you would still expect much lower performance than the PS4.

If DDR3 only made a difference of single digits then both companies would just use that instead of using the GDDR5/ESRAM options.

I was trying to find some like-for-like comparisons of DDR3 vs GDDR5.  Here's some.

Here's another on more similar hardware to PS4/XB1 (HD 7750).

Scene Card 720p (avg)
Dark Tower AMD HD 7750 1GB GDDR5 53.12
AMD HD 7750 2GB GDDR3 34.15
Desert Sunrise AMD HD 7750 1GB GDDR5 72.03
AMD HD 7750 2GB GDDR3 50.41
Concrete Jungle AMD HD 7750 1GB GDDR5 41.64
AMD HD 7750 2GB GDDR3 27.04

And this:

Basically as soon as they picked DDR3 with any combo is worse than GDDR5.  Lower # of CUs with ESRAM is slower.  Same number of CUs without ESRAM is slower.
