Microsoft tackles Xbox One vs PS4 performance “mis-information”

The PS4 will not have the performance advantage over Xbox One that many people seem to believe.

That’s according to Xbox strategy boss Albert Penello, who has taken to NeoGaf to correct what he calls some of the “mis-information” that has been poste don the internet.

Here are his technical points in full:

• 18 CU’s vs. 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.
