It all depends on settings.  I play on a 780 Ti, which performs equivalently to a 970 (but with less memory).  Many games can be played at 4K&#x2F;medium and maintain reasonable framerates (45-60 fps) - FO4, Mad Max, TF2, etc.  I had a R9 280 (aka Radeon HD 7950) before that, and it was surprisingly good at 4K too considering its age.<p>You only need multiple Titans if you insist on 4K ultra with everything turned up all the way.  Consoles typically don&#x27;t do that, it&#x27;s always a graphical compromise to make the hardware work at some reasonable level of graphical fidelity.  And typically they only target a 30fps framerate anyway.<p>I have to make the same compromises myself - some settings hurt much more than others as you increase the resolution, but you can find some balance that looks good.  Anything that can&#x27;t be played at 4K can be played at 1440p High or 1080p Ultra and upscaled.  4K is pixel-dense enough that some destructive resizing from 1440p isn&#x27;t a big deal, or 1080p scales perfectly 4:1.  Right now most consoles are doing medium-quality 720p and scaling up the output, so ultra-1080p is still a big step forward compared to a console.<p>Right now the Playstation 4 has 1152 GCN 1.0 cores, so it&#x27;s between the performance of a Radeon HD 7850 (1024 GCN 1.0 cores) and the 7870 (1280 cores).  Something in the 390 or 970-class would probably be reasonable, that&#x27;s about 80-90% faster.  Maybe 980 or 390X-class on the high end, which are 100-110% faster.  And remember that on consoles you get the benefit of a single hardware set that you can optimize for, and play low-level micro-optimization tricks with (GCN is <i>great</i> for this).<p>Nobody knows where the new Polaris&#x2F;Pascal chips will fall on the scale, but that performance tier will probably be considered a midrange chip at that point.<p>Do I think Sony will invest that much in a premium hardware configuration?  I have my doubts.  But it&#x27;s certainly <i>possible</i> to make an engineered solution that will play 4K@30fps reasonably well inside a console footprint, particularly once we get the node shrink from Polaris&#x2F;Pascal.
