In these hours, Digital Foundry has conducted a series of special comparison videos, having placed two consoles of different generations opposite each other, such as the Xbox Series S and the PS4 Proto, to see what may arise from two machines that, on paper, have the same number of teraflops as power.
The results are quite predictable, although it is unclear whether or not it is a form of provocation. PS4 Pro would have even more, since it would have four teraflops rather than four, as the console Microsoft currently has.
The similarities in graphics modes are similar to those in Xbox Series S, and the resolution is usually the same between the two consoles, however, the PS4 Pro lacks many features that are present in Xbox Series S, particularly those related to the new generation architecture.
Ansonsten, the Xbox Series S has excellent performance and is generally more stable, as well as better-tuned effects, more complicated geometry, and less flaws.
The distinction appears to be rather arbitrary, being made between two consoles with two different generations. The sense might be found in the fact of discrediting the theory of the number of teraflops as an indicator precisely of a machine's ability, given that in this case a series of further different characteristics take over to modify the results, between new generation GPUs, more powerful CPU, SSD and more RAM.
