Yes there is another reason. It's kinda impossible. If the PS4 neo is using the same CPU with the base PS4, even if over clocked from 1.65GHz to 2.2GHz, it won't be able to take a game that was at best running at 30-40fps internally on the PS4 base up to 60fps on the Neo. That will only be possible if the game was running at 45-60fps internally on the base PS4 and locked to 30fps for stability. then in that case the slightly more powerful CPU could carry it up to 60fps. If at 1.65ghz a game is already struggling to hit 30fps on the cpu side you basically need twice the clock is using the exact same cpu architecture or a more powerful CPU architecture entirely if you want to double the fps. |
This assumes that the game is CPU limited and not GPU limited. You can take a 5 year old CPU and GPU then upgrade only the GPU to the most modern verison and get more than double the performance in game. So yes, if the game is CPUlimited then it may not be possible for it double the FPS, however, from all my years of experience with PC's though this is rarely the case. Most games do not depend on the CPU much and rarely utilize more than 50% of the CPU. When you have a huge came with a lot of AI, massive maps and 64 players like MAG ( PS3) or any of the Battlefield games, they do become partially CPU limited but still see a massive increase in performance by only upgrading the GPU.
For examply, my current system has a now 5 year old CPU. When I had my GTX 870 I averaged between 45-70FPS on Battlefield 4. When I upgraded to a GTX980 I now get between 70-120 FPS and I never drop below 60. I did not change my CPU, RAM, or Motherboad, just the GPU.
It is very possible to acheive a massive FPS increase with a slight CPU overlcock and a new GPU.
