No, the original quote (I think it was from Digital Foundry) was that purely running RT on unified shaders would require 13TF of compute, however that has been offloaded on to dedicated hardware. So the Xbox has 12TF of traditional shader compute and additional 13TF of ray tracing compute, which added together is "25TF".The reason i believe for the 25TF is that normal calculations are 32bit in it's 12TF mode, for RayTracing the calculations can be done in 16bit and thus 2 calculations can be done at once thus the 25TF number appears, it's called Rapid Packed Math i think and the PS Pro had it aswell. So it's not like it can operate in this mode for everything but only for select things, which in this case is RayTracing.
All of this is absolute bollocks, and whomever decided to make this bullshit up is preying on most console fans having little understanding of the technology. Its misleading bollocks.
