To comoensate for the slow DDR3 ram ms has to put SDram on the die of the APU which took up space. The only way they can have an APU that is idemtical to what the Neo is rumoured to have is of they are doing away with the sdram.... that however stands to break compatibility for every already existing XB1 game, or they get all of them patched to support the new hardware, or they use a memory system so powerful that the new hardware can emulate the sdram...... complicated. 

It's ESRAM. Actually it would be at least possible for Scorpio to maintain ESRAM or eDRAM as cache. Question is, is it neccessary? If the system memory is fast enough there should be other solutions like mapping a little bit of system memory for caching.

lol some people are really nervous by a more powerful XBox.

From what we know Neo is not a full blown Polaris, it might be based on certain things but it's basically just a PS4 GPU x2 overclocked a bit.

A Polaris 10 at 32 CUs is 5.5 TFLOP, so that's obviously not the part Neo is using. 

XB2 from the sounds of it will be more like a brand new Polaris 10 (custom), which would enable it to hit 6 TFLOPS without much problem at a reasonable price/power consumption.

Sony is likely hamstrung here by having to stick with something close to the older PS4 architecture, otherwise at 36 CUs they should be getting better performance than just 4 TFLOPS-ish. 

Full blown Polaris is 40 CU and 2560 shader units. AMD has already deactivated some compute units for the first GPU's. Looks like hey're going for highest possible yields first. Leading to the 36 CU and 32 CU versions.

FLOP/s (single precisision) number of shaders*2*clockspeed in GHz=TFLOP/s

So there's no X compute units is Y TFLOP/s. One of the last benchmarks showed a 36 CU Polaris 10 at 1.266 GHz.
