PS5 vs XSeX: Understanding the Gap

I think its obvious how and where the advantages would show themselves. All we have to do is look at the PS4/XB1 and the pS4pro/XB1X. Then take into account just how different those consoles were from each other respectively.

The "gap" or "power difference" people are alluding to, while there, is nowhere even close to as significant as any of the aforementioned comparisons.

A simple way to ut it, not only does the upcoming gen represent the smallest gap ever between two PS vs Xbox consoles at launch, the bar has collectively been set so high that it gets really hard to spot the difference. For reference, watch the RE3/Doometernal digital foundry videos. Look at the XB1X vs the PS4pro. Then remember that the XB1X has a 50% compute advantage, 50% RAM bandwidth advantage and 50% More RAM.

Perhaps you've quite a liberal interpretation of the words 'nowhere close'.

There is a gap of 20% at peak performance. We know from Sony peak performance is theoretical, because the CPU or GPU will be throttled. What they have not told us (somewhat concerning, given they had a whole hour conference), is their minimum performance. I.e. What is the minimum simultaneous performance of the CPU and GPU the PS5 can sustain. 

In terms of the components for which we have the most evidence, the minimum gap is 20%. The maximum gap is unknown, until Sony tells us or a tech company gets a hold of the final product and tells us for them.

Again, until we see games, all we know is that the Xbox is more capable, and that this capability gap may well be moderate, or could be more significant.

Edit: Obviously not going to engage with your PS4P Vs XOX argument given you deliberately left off the fact they each have near identical CPU bottlenecks - that way be dragons.

The Xbox One X's CPU bottleneck is not the same as the Playstation 4 Pro's.

Not only does it have a 170Mhz (7.9%) advantage, but the Xbox One X had a significant amount of engineering to offload CPU tasks onto the Xbox One X Command Processor, things like draw calls which eats a ton of CPU time for example... Plus other minor improvements like the page descriptor cache.

2. Jesus... twisting words much? Yes. I said it would actually be harder for the XSX to hit its clocks. I was speaking design-wise. Its generally harder to get bigger chips (XSX) than it is to get smaller chips (PS5) to hit their clocks. And YES, its easier saturating the CUs of a smaller chip than it is o a larger chip with more CUs. these are all known facts. And I ai al that in a replay to someone. 

Depends on the efficiency curve. 1980Mhz is the top-end that RDNA 1.0 can achieve without much drama. RDNA 2.0 likely features additional improvements to push up clockrates.
