Though the XBOX 360 is good in theory, it's hardware limitations say otherwise - Hideo Kojima

Laughed at this post, then closed the topic.
The rumor is this:
Back when both consoles were in the design phase, GDDR5 was still only being produced with chips that would make 2GB reasonable. MS needed a lot more than that, so early on went the route of DDR3 which they knew they could get in the quantity they wanted. Both console makers then designed their APU's around this, MS putting in the ESRAM at the cost of the GPU portion to mitigate the bandwidth loss of DDR3.
However, things went sideways when the chip makers not only rolled out 1 size, but 2 sizes bigger of GDDR5 chips, allowing Sony to switch to 8GB as well. However, by this point, MS was already set in their plans (both chips have memory controller inbuilt so changing them isn't really an option in late development) so they are stuck with DDR3. So essentially, Sony got lucky.
Now, a couple things. Number one, DDR3 does NOT have lower latency. It has a per cycle lower latency, but because GDDR5 is clocked higher, it actually has the lower actual latency. Two, although this one I've yet to see confirmation on, since GDDR5 is DDR3 under the hood (the only difference is the memory controller) it is possible that PS4's CPU's memory controller might treat it as such, but again I have never seen that confirmed.
As to the ESRAM, it is meant to mitigate the difference. Make no mistake, it is needed. The DDR3 is just not fast enough by itself to cover the bandwidth needs of the GPU, even though it is a weaker one. It is debatable if GDDR5 would be overkill for the GPU, but DDR3 is definitely not enough. MS wouldn't have put the transistor budget of their APU to the ESRAM if it wasn't needed.

The rumor is this:
That's the rumour. The reality is more likely the following:
MS built a PC basically whilst Sony aimed at building a gaming specific system. So if you look at how the XBOne is designed, you can easily tell that it was built very much like traditional PCs would be built, instead of prioritizing everything for the video card, they've prioritized the box to handle general tasks better. It's very likely that MS looked at the memory more as general system memory rather than looking at memory the way Sony did. What Sony made with the PS4 is like they made a really nice video card with a computer hanging off of it.

good one, should have used a small barely visible font.
It was an intelligent choice, like calling it the Xbox One, mandatory Kinect, and that end of May reveal that was all about TV & Sports parterships.

Not worse, at all. It goes from the same to faster for small memory, huge IO operations.
TC, they went DDR3 because it's cheaper and it provides a good compromise between performance and price.

So that ZenGamer64 would create this topic.

Im using DDRG4 and it gives a smoother television signal, Sir.
