Which graphics card can you compare with that of the Playstation 4?
Ps4 non Pro?
Radeon HD 7870, GTX 580, 660ti.
The graphics card is roughly on par with an ATI7870 or Geforce GTX 670. But you can't really compare that anyway. A console gets more out of its hardware than a PC because it is highly specialized. Still, current PC hardware is far superior to a PS4. But it doesn't do you much good if most developers develop primarily for consoles for cost reasons and then simply port them to the PC. You hardly have any pure PC developments that draw on the full.
Comparable to an ATI7870 or Geforce GTX 670.
Both ^^
The Playstation 4 PRO is on the same level as an RX 580. The raw performance of the normal PS4 is no longer completely in my head
The Pro is more like an RX 470/570 or 1050ti.
Mean more like 470/570 ^^
They are so close together, that is measurement tolerance. The Playstation 4 Pro gets about as much out of the hardware as the rx580 can do
A console gets more out of its hardware than a PC because it is highly specialized.
Not quite. It is so that the consoles offer uniform hardware and thus the software can be optimized for precisely this hardware.
"just"?
Yes, only because the games are optimized for consoles and thus games can run better ^^
Yes, it is already relatively old. It's always like this with consoles. The new consoles are also based on the midrange chips of the next GPU's (Navi 22 equivalent).
