Everyone knows GDDR5 RAM is more beneficial for GPU memory. System memory however is actually better off with DDR3 RAM due to sligtly lower latency.
In terms of next gen console GPUs, below are the specs:
PS4 GPU Cores - 1152
Xbox One GPU Cores - 768
and
PS4 Peak Shader Throughput - 1.84 TFLOPS
Xbox One Peak Shader Throughput - 1.23 TFLOPS
Xbox One GPU has 33% less cores and 33% less peak shader throughput. Due to this, it needs less video bandwidth than PS4.
This leads us to video RAM:
PS4 Video Memory Bandwidth - 176 GB/s
Xbox One Video Memory Bandwidth ( DDR3 + sRAM cache) - 102 GB/s
Xbox One would not benefit at all from having 176 GB/s GDDR5 bandwidth due to lower GPU throughput. If they gave the Xbox more GPU cores it would be a different story however its RAM bandwidth is perfectly proportional to the GPU performance.
Its no secret that Xbox One has a less powerful GPU, but because it skipped on GDDR5 memory it can enjoy better system RAM, much less power consumption and heat, and cheaper manufacturing cost.
Just an FYI to those that say Xbox One is at a disadvantage for not having GDDR5 RAM.

I bet AMD feel stupid for using GDDR5 on there Radeon 7770, if theyd of talked to MS hardware designers they could of saved alot of money.
Also is this a stealth troll lol? Doesnt matter if they chose crap ram, cos they have a crap GPU meaning its cheaper for them to make and thats why its more expensive!

1. AMD doesn't feel stupid because they only had a 128 bit memory bus on the 7770.
2. No its not a stealth troll. Its a thread explaining that Xbox One is a perfectly balanced console in terms of performance without GDDR5.
Looking at different fonts in your post and highlights, looks like you're copying and pasting things from other sources. Sure beats knowing and understanding things...
