Re. the thread title:
PS4's GPU is 50% more powerful than Xbox's.
Xbox's GPU is 33% less powerful than PS4's.
Eurogamer said:In terms of the GPU hardware, hard information was difficult to come by, but one of the engineers did let slip with a significant stat - 768 operations per clock. We know that both Xbox One and PlayStation 4 are based on Radeon GCN architecture and we also know that each compute unit is capable of 64 operations per clock. So, again through a process of extrapolation from the drip-feed of hard facts, the make-up of the One's GPU is confirmed - 12 compute units each capable of 64 ops/clock gives us the 768 total revealed by Microsoft and thus, by extension, the 1.2 teraflop graphics core. So that's another tick on the Durango leaked spec that has been transposed across to the final Xbox One architecture and the proof we need that PlayStation 4's 18 CU graphics core has 50 per cent more raw power than the GPU in the new Microsoft console. Now, bearing in mind that we fully expect PlayStation 4 and Xbox One to launch at similar price-points, how did this disparity come about?

The answer to that comes down to a specific gamble Sony made that Microsoft could not - the utilisation of a unified pool of GDDR5 memory. In the early days of PS4 development, only 2GB of this type of memory looked viable for a consumer-level device. As higher density modules became available, this was duly upgraded to 4GB. By the time of the reveal back in February, Sony had confidence that it could secure volume of 512MB modules and surprised everyone (even developers) by announcing that PS4 would ship with 8GB of unified GDDR5 RAM. The design of its surrounding architecture would not need to change throughout this process - one set of 16 GDDR5 chips would simply be swapped out for another.
Microsoft never had the luxury of this moving target. With multimedia such a core focus for its hardware, it set out to support 8GB of RAM from day one (at the time giving it a huge advantage over the early PS4 target RAM spec) and with serious volume of next-gen DDR4 unattainable in the time window, it zeroed in on supporting DDR3 and doing whatever was necessary to make that work on a console. The result is a complex architecture - 32MB of ESRAM is added to the processor die, along with "data move engines" to courier information around the system as quickly as possible with bespoke encode/decode hardware to alleviate common bottlenecks. Bottom line: if you're wondering why Xbox One has a weaker GPU than PlayStation 4, it's because both platform holders have similar silicon budgets for the main processor - Sony has used the die-space for additional compute units and ROPs (32 vs. 16 in One), while Microsoft has budgeted for ESRAM and data move engines instead. From the Xbox perspective, it's just unfortunate for Microsoft that Sony's gamble paid off - right up until the wire, it was confident of shipping with twice the amount of RAM as PlayStation 4.
Huh?
Interesting Part on the memory, GPU, and price:
It might be best for the Anandtech thread to get merged with this one and the OP edited to include bits of both, but no, I don't think there's a thread for this yet.
Interesting Part on the memory, GPU, and price:
There's really no doubt that the PS4 is significantly more powerful - a larger gap than we all thought a year or two ago.
The question is, will developers take advantage of it? Sony's studios will. What about everybody else?
Yep. If you have two apples and I have three, I have one apple more than you. One apple is half of your total amount of apples. This mean I have 50% more apples than you. At the same time, you have one apple less than me. One apple is one third of my total amount of apples. This mean you have 33% less apples than me.Huh?
That's quite a power gap.
and yet I keep hearing the gaming press say things like "they're pretty much the same".

Behind the cooler we have a standard 2.5-inch hard drive. Microsoft says that it's not user-replaceable, meaning that 500GB is your lot in terms of internal storage
It'll be interesting to see what Brad says on the bombcast next week. He's been saying they're the same for six months, and DF is the only tech source he ever mentions on the show.That's quite a power gap.

I think this "gamble" idea is a bit oversold. There are roadmaps for memory manufacturing, and it's not a "gamble" to assume that technology improves.
That's why I always found it so hard to believe that people in past next-gen speculation threads doubted even 4 GB GDDR5 for 2013 boxes.
Damn EZE they tried to fade you on Dre Day.Talkin about who you gon squabble with and who you shoot,
You're only 60 pounds when you're wet and wearin boots.
Can someone please do a gamecube calculation for those that don't speak tech talk?
