Report: Xbox One's capabilities better than Microsoft expected

AMD's Jaguar powers both X1 and PS4
According to sources, it seems that Microsoft severely underestimated the processor performance of the Xbox One by a factor of 88%, as evidenced by the capabilities of the final hardware.

While the PlayStation 4 uses a 8GB unified pool of GDDR5, the Xbox One uses DDR3, which is alleviated by 32MB of "embedded static RAM". This means that bandwidth is more of an issue in the Xbox One. However, Microsoft thought that the console would peak at 102GB/s (as compared to the PS4's 176GB/s), but now sources say that Microsoft has revised the figure, saying 192GB/s is theoretically possible. However, practical estimates put the rate at 133GB/s with alpha transparency blending operations.

Why the goof up? Microsoft took its calculations from a basic figure: 128 bytes per block multipled by the GPU speed of 800Mhz. What the techs didn't know what that the hardware was capable of reading and writing simultaneously.

Generally, the main issue is that this seems to contradict earlier rumors that the CPU of the Xbox One is being downclocked. According to sources, 800MHz remains the clock speed of the graphics component of the processor, and the main CPU is operating at the target 1.6GHz, which keeps parity with the PS4. In essence, the machines are taking different routes to the same goal, with the PS4 having a slight edge in processor speed.

88%? Yea right :).
This sounds way too bogus.

Oh lookie I can lift 88% more than I thought I could, you simply can't make such a huge mistake. Even those 30% are huge.

They didn't know the hardware could multitask like that.

That somehow makes those 30% seem probable but the 88% theoretical figure completely sounds like a PR stunt to me. And yes I know I am being a bit negative when it comes to MS these days.

If this is true then I don't know what to think, one would assume that AMD explained these basic things to them.

You'd be surprised. I've seen what the Xbox One can do - it's not much different than the PS4 at this point.

Hardware differences don't manifest themselves til like 2 years after launch after devs have gotten used to the systems.

if the specs are the same but ps4 is cheaper then that`s still the one people are going to buy.

Does this basically mean that they previously estimated Xbox One to be only half as strong as PS4?
I'd be pretty pi**ed at AMD if they did that to me, the price sure didn't seem to reflect the perceived performance difference.

Yeah something doesn`t quite fit here does it?

And now, the price will go up by only 30%! Yay!

Keep an eye out for an Xbox One subsidy much like the Family Deal with the Xbox 360: pay a low price now if you commit to a monthly Xbox Live subscription for a year or two, much like you do with cell phones these days.

Those contracts usually mean that you're overpaying for the phone by the end :).
But considering you need that Xbox sub to be able to play online anyways it would still probably be a good deal.

It's all moot. People buy consoles because of the games they have on them, and to match what their buddies bought. People will pay a little more for a console that isn't quite as powerful if it gets them the right games and gives them something in common with their friends.

But a 50% difference in performance would surely have mattered at least a bit?

As a PC gamer, it sound like you guys are arguing about which is better: KFC, Hungry Jacks/Burger King or the Golden Arches. Me? I'll stick with fine dining.
