Let's take the same logic here, apply it in PS4 vs GTX Titan GPU.
PS4 will catch up to GTX Titan. Here's why:
- Those extra pixels and anti-aliasing the GTX Titan can do are not even discernible to the human eye sitting 1 foot away from the TV.
- The Titan GPU may be 2.5 times faster than PS4, but that doesn't matter if it can't actually fit in RAM. PS4 has 8GB GDDR RAM and GTX Titan has only 6GB GDDR, therefore GTX Titan can not do any more than PS4.
- Developers can not afford to ignore the PS4, so the games will only be made up to PS4 level.
Conclusion PS4 is at least as, if not more powerful than GTX Titan.
