The NVIDIA Quadro M4000 is a Maxwell-based Quadro GPU (GM204) announced at Siggraph 2015. Along with 8GB of GDDR5, 4 DisplayPort outputs, 4K monitor resolution support, SLI, Stereo, and Sync support, this is a GPU with power and potential that comes in at a price around $1000.
PW tested the GPU in a new Skylake workstation with the Intel Xeon E3-1275 v5 clipping along at 3.6 GHz. Scroll down to jump to the performance numbers. We'll start with a look at the outside of this new professional GPU.
The Quadro M4000 replaces the K4200 and corrects several deficiencies in the older GPU. First, it increases display support to 4 outputs - this time all of them are DisplayPort. Apparently, the K4200's Kepler architecture could not support 4 DisplayPort outputs which the Maxwell architecture does. This allows the Quadro M4000 to support a modern display configuration.
The K4200's 4GB of GDDR5 memory has been increased to 8GB - another point where the Santa Clara graphics experts needed to play catch-up. While there are certain graphics situations which like the extra 4GB of memory, it is critically important for CUDA and GPU-computing applications in areas like simulation. The memory has a 256 bit interface and a 192 GBps bandwidth which places the M4000 memory performance close to its big brother the M5000 and much faster than the K2200 and K1200 GPUs.
