Penello says “PS4 power over Xbox One overstated”

Blames internet people for spreading misinformation.

Xbox’s Albert Penello commented on a post on NeoGAF, saying that, though “not disparaging Sony… the way people are calculating the differences between the two machines isn’t completely accurate. I think I’ve been upfront I have nothing but respect for those guys, but I’m not a fan of the mis-information about our performance.”

He then went on to clarify “misunderstood elements” of both consoles’ architecture, like the Xbox One’s lower amount of Compute Units leading people to believe it’s at a power disadvantage.

“So, here are couple of points about some of the individual parts for people to consider.

• [PS4's] 18 CU’s vs. [Xbox One's] 12 CU’s =/= 50% more performance. Multi-core processors have inherent inefficiency with more CU’s, so it’s simply incorrect to say 50% more GPU.
• Adding to that, each of our CU’s is running 6% faster. It’s not simply a 6% clock speed increase overall.
• We have more memory bandwidth. 176gb/sec is peak on paper for GDDR5. Our peak on paper is 272gb/sec. (68gb/sec DDR3 + 204gb/sec on ESRAM). ESRAM can do read/write cycles simultaneously so I see this number mis-quoted.
• We have at least 10% more CPU. Not only a faster processor, but a better audio chip also offloading CPU cycles.
• We understand GPGPU and its importance very well. Microsoft invented Direct Compute, and have been using GPGPU in a shipping product since 2010 – it’s called Kinect.
• Speaking of GPGPU – we have 3X the coherent bandwidth for GPGPU at 30gb/sec which significantly improves our ability for the CPU to efficiently read data generated by the GPU.”

He stated his team gets “little credit” for all the work they’ve poured on the console’s software, and compliments them, saying that having “some of the smartest graphics engineers” on board for Xbox One is “overlooked when evaluating both boxes”.

Then, he continued his speech, closing with: “Given this continued belief of a significant gap, we’re working with our most senior graphics and silicon engineers to get into more depth on this topic. They will be more credible then I am, and can talk in detail about some of the benchmarking we’ve done and how we balanced our system.”

    I just want to play some damn games! It’s not the size of the hardware but how it is utilized dammit! Haha.

    Agreed! Bring the games and stop all this rubbish!
