Today NVIDIA announced two professional graphics cards based on the Maxwell Graphics core, the Quadro M5000 and M4000 Quadro, both graphics cards share the Maxwell GM204 although with minor differences.

NVIDIA launches Quadro M5000 and Quadro M4000


The NVIDIA Quadro M5000 uses Maxwell GM204 with CUDA Cores 2048 , 128 TMUs and 64 ROPs at a frequency of1050 MHz  accompanied  8GB GDDR5 @ 6.60 GHz memory interface coupled with 256 bits  which gives a bandwidth of 211 GB / s  with floating point performance of 4.3 TFLOPS  leading to a consumption of 150W.

Furthermore, the  NVIDIA Quadro M4000 uses a cut down / harvested version of Maxwell GM204 with CUDA Cores 1664 , 104 TMUs and 56 ROPsat a frequency of 800 MHz, which keeps 8 GB GDDR5 but @ 6.00 GHz together with memory interface  256 bits  gives a bandwidth of 192 GB / s  with floating point performance of 2.6 TFLOPS.

The cut down Graphics core help it in lowering the power consumption to the 120W, allowing the use of a cooling system that occupies a single PCI expansion slot  (Vs two of the M5000). The price of both professional GPUs is not announced.
