agreed on most of it, but again, we have nothing to go on in terms of TFLOP performance on both consoles so it's pointless to be doing these calculations. One thing that I haven't seen mentioned yet is the eSRAM debacle, so if they adopt the GDDR5 like Sony did, that will mean a change in memory management compared to the current console (using DDR 3 + eSRAM), so I'm not sure how easy it would be to play the current games on the new console. In all honesty I'm thinking they will have pretty similar specs this time around.

I dont think they can make the next Xbox One-ii, without eSRAM.

It would probably break compatability with the older Xbox One games, or force them to jump through alot of hoops, to get games running on both.

 

I actually think its one of the smarter things Sony did when they designed the PS4.

They went with 1 pool of memory, its much much easier to code for, it ll scale well with time, makeing it really cheap in the long run.

It ll allow use of HSA compute methodes you cant do unless you have 1 shared memory pool.

They can either stick with GDDR5, and just find faster clocked ram, or go with something new like GDDR5X.

 

Meanwhile the design choices of the original Xbox One, are still gonna impact this next box (if their forced to use eSRAM again).

yeah, it's my #1 question mark on this whole project. Many might not remember nowadays, but the main reason why the Xbox 1 was underpowered compared to the PS4 was exclusively due to the need for eSRAM. The amount of CU had to be lowered in order to have space in the die for the eSRAM which in the end brought the performance difference to around 40%/50% compared to the PS4.

now, I confess I'm not 100% sure on what the impact of changing eSRAM to GDDR5 will be. there are 2 options here

1- go for GDDR5 and (maybe) impact the compatibility with the older titles, basically separating their audience between new and old hardware, but actually have performance parity (maybe advantage) with the PS4 Neo

2- keep the eSRAM on the APU and scratch the idea of the 6TFLOPS people are spreading around, they'd be back behind the PS4 in terms of performance, as well as unable to lower the cost by much.
