PS4 holds a spec advantage over the Xbox One. The system has better RAM but the CPU is quite similar. So what about the GPU?
Microsoft has not released the official specs of the Xbox One GPU, but we do know the rest and people have figured out the GPU’s capabilities. It’s 30% weaker than the PS4 in theoretical performance and this image below explains what a big difference there is between them both.
The PS4 GPU can provide 1.84 teraflops of power, while the Xbox One GPU is rumoured to be 1.24 teraflops.
The clock speeds are quite similar although there have been rumours of a recent downgrade, but nothing is confirmed so far.
The PS4 GPU is drastically better and will probably show in multiplatform games. However, if developers use the Xbox One as a lowest common denominator and develop using its specs, then we won’t be seeing a lot of differences between the two.
It also depends on the install base, and considering the Xbox 360 had an advantage last gen, the PS4 could have one this gen due to its lower price and superior specs.
