the consoles are jumping from 1.31 tf to 6tf and 1.81 to 4.6 tf , very massive jumps 1080 ia pretty much the standard on ps4 |
You can have a 1 Teraflop GPU beat a 2 Teraflop GPU. You cannot use that as a way to gauge performance.
The performance jump should be less than what the Teraflop increase may imply as memory bandwidth, CPU speed, cache sizes, speed and latency and even things like the Render Output Pipelines and Texture Mapping Units are NOT seeing the same kinds of increases as the single precision floating point performance. (Tf/Teraflop/Tflop)
Rendering a game needs more than just ample amounts of single precision floating point performance.
With that said on the flip side, the performance increase should be more than what the overall specs sheet tells us due to efficiency optimizations that allow for more performance out of every pixel pipeline (AMD is saying 55%), boost to the geometry engines, bandwidth savings thanks to colour compression etc'.
