Claims of PlayStation 4’s alleged superior hardware in comparison to the Xbox One have been ‘greatly overstated,’ according to Microsoft’s Albert Penello.
Writing on NeoGAF, the executive lambasted pockets of the gaming community for promoting “misinformation” regarding the technical performance of Microsoft’s next-generation console.
While Penello insisted he was “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.
“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.
PS4 is due for release in the U.S. on November 15 and arrives in Europe on November 29. Xbox One meanwhile is scheduled to ship on November 22.
