I had a bit of a look at the tech behind the new X-box and PS5. On paper the Xbox has more cores, but the PS5 runs them faster. Generally speaking you shouldn't be able to tell much difference in processing speed from that.
However, PS5 has a very fast SSD, and the tech in the pipe to use it. If everything pans out for them the games will effectively be no loading times for area transitions. Which means that will give them an advantage over the PC in that area too.
Overall though if you think it's worth it get both for exclusive games, otherwise consider the PS5.
Not quite correct.
They are basically the same AMD chipset with modifications. What you may have read with the cores is the clock rates are higher on PS5 but that is turbo. There is a smaller threshold for thermal throttling so that will slow down to less more often than not. So PS5 you may get full grunt for your first 15/30 mins gaming but then it will clock down. One of the reasons why the PS5 is soo big is because of the rumoured heat issues they have been facing internally.
The Xbox will run full tilt for longer. Digital Foundry did a bit on all this.
The SSD stuff more has come out with more of a breakdown on it. They are all but the same SSD. With Sony releasing the viable SSD list and information on what and how external drives would work along with their throughput process Sony has custom chipsets to control the data flow out of the SSD reducing a lot of latency. Very clever and one of the good decisions they made.
Microsoft have said they have some stuff as well there but not provided as much detail.
In terms of the GPU - they are basically the same on both consoles but Microsoft requested some different things and their GFlops are higher but nothing else really is known around that. There is talk that the xbox is also running a kind of discreet graphics chip that they are actually using to run Xbox OS/UI elements rather than the CPU or GPU.
