GeForce GT 755M Mac 

Released November, 2013
  • 1.1 GHz
  • 1 GB GDDR5

As for the Boost clocks, in practice that can increase the GPU core speed 15% or more over the normal value, with most games realizing a 10-15% performance thanks to the increase.

These chips are still based on Kepler (600-series), but feature more CUDA cores, more memory, a wider memory bus, and faster clockspeeds.

Namely, while the iMac used its dGPU exclusively the MacBook Pros all used switchable graphics, which means that the MacBook Pros are often being driven by their iGPU rather than their dGPU.
While the 2011 iMac and MacBook Pros use different GPUs, both systems use GPUs from AMD’s Radeon HD 6000M series, with the iMac using the higher-end 6970M while the MacBook Pros used the 6490M, 6750M, and 6770M GPUs.
