| Zappykins said: It seems both the NextBox and the PS4 are both underpowered for what the designers of Unreal Engine wanted. I remember them wanting 2.5 Tflops and neither one has crossed even the 2 barrier at this point. What I am referring too was from the Samararian Demo in 2011. |
Pretty much. Both consoles are well below expectations wrt to UE4. To hit 2.5 Tflops, they would have needed to use a 1Ghz HD7870. That card uses 115W in gaming. http://tpucdn.com/reviews/VTX3D/Radeon_HD_7870_XT_Black/images/power_peak.gif
My guess is both MS and Sony are being extremely cheap this generation. Launch PS4 used 240W of power. So 115W of power consumption for the GPU cannot be the reason they aren't going with a desktop HD7870. My guess is MS and Sony will try to stand out with other gimmicks like multi-touch on DualShock 4 or Kinect 2.0 instead of spending more $ on the GPUs.
