According to an article at Edge Online, the PS4 is currently around 50 percent faster than the Xbox One.
According to their contacts, who are supposedly “multiple high-level” game developers the PS4 memory reads are 40 to 50 percent faster than the Xbox One, and they state that the “ALU (Arthimetic Logic Unit) is around 50 percent faster.”
Microsoft as of late has been tweaking their specifications and trying to close the gap on the PS4. But according to their sources “The clock speed update is not significant, it does not change things that much,” he said. “Of course, something is better than nothing.”
With the launch of both consoles coming in about 2 months both Microsoft and Sony are still working on their graphics drivers, but Sony seems to be ahead of Microsoft. Another source stated that at this point Microsoft’s Xbox One graphics are “horrible”. But as time moves forward and driver updates occur the gap may close between the two rivals.
Microsoft’s Xbox One does have a leg up with performance in other areas. ““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,” a developer said.
The third-party titles at launch are likely to be very similar due to some studios feeling that they will need to “castrate” the PS4 version to not upset Microsoft or save costs in development rather than trying to make one platform look “prettier” than the other.
As time moves on it appears that the PS4 has the superior hardware and may be the wiser choice for hardcore gamers that want to have the best hardware.
