Same as the PS4 Pro: it's significantly more powerful, has more storage, can actually do RT well, etc.
The price seems crazy to me though.
E: it's occured to me that the PS5 Pro pricing is likely a (comparatively small) release that they can test the waters for a $700 PS6.
If they release the PS6 for $700, it could backfire and compromise that entire generation, giving MS a foothold (we saw how MS ran away with the 360 when Sony botched the PS3 launch, and subsequently how MS lost all that momentum when they botched the XBone launch, and Sony ran away with the PS4).
If they test the waters with a PS5 Pro it doesn't matter all that much if they have to capitulate and drop the price.
Don't show Sony that the market is willing to pay $700. The PS5 Pro being accepted at $700 will guarantee a base PS6 at about the same.
An uplift of ~45% in overall performance, ray tracing going from awful to decent, hardware-accelerated upscaling (like DLSS) isn't "hardly noticeable" unless you don't have eyes.
And more storage and WiFi 7 may not be as flashy (hah, SSD storage, flash-y), but they're nonetheless improvements.
But, you know, if that's not good enough for you, don't get one. Nobody's forcing you. I know I have no desire for one, (especially not for $700!) I've been console-free since my 360 had a red ring of death.
Only if you don't have one already. Some of the more intense games graphically have shit upscaling so they shimmer. If higher internal resolution can fix this while running at good FPS, it might be worth it for some people
Remember that you still can't build a gaming PC for $700 that performs similarly.
Pro revisions are the time to go crazy with outrageous prices since they're not needed to be able to play any of the games. But if they try that crap with a base model, it's PC Master Race time for me.
