According to UK magazine Edge, anonymous reports have claimed that the PS4 is significantly faster than the Xbox One. The magazine reports that the PS4 memory read is about 40-50 percent faster than that of the Xbox One. The arithmetic logic unit on Sony’s graphic card is also reportedly twice as fast as the Xbox One.
For an example, a mutliplatform title can run at a resolution of 1920×1080 at 30fps on the PS4. That very same title would drop in resolution to 1600×900 and will run only at 20fps. This claim might very well be true, Microsoft did bump up their clock speed right before the Xbox One officially shipped out. But this bump didn’t do much for developers in terms of performance. However, one developer reports that the Xbox One does have some advantages over the PS4.
“Let’s say you are using procedural generation or raytracing via parametric surfaces–that is, using a lot of memory writes and not much texturing or ALU–Xbox One will be likely be faster,” concluded one developer.
In conclusion, launch titles will run a little bit better on the PS4. However, as highlighted in the report, developers won’t adhere to releasing an inferior version of their product on the Xbox One.
“It would be totally fine for us to make one version prettier without any political difficulties but it usually doesn’t make financial sense,” said the developer, “unless it’s a very simple tweak.”
The Xbox One is set to launch on November 22 globally. The PS4 is set to launch on November 15 in the North America and November 22 in Europe.
