Digging into the Quadro M4000

For many people, 1664 is a not-so-great-tasting French beer. For PW, it is the number of CUDA cores on a Quadro M4000. Check out the performance and the possibilities ...

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.

NVIDIA now supports more DisplayPort outputs and can drive four 4K resolution displays from the Quadro M4000

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.
