The Quadro P4000 has 8GB memory with a 243GB/s bandwidth, is only 105W, 1792 CUDA cores, supports 5K resolution. However, unless there is a current cooling colution for the K40, as the K6000 and K40 are worth ~$800, consider alternatives. In my view, the K6000 is currently valued at about $600 used and the K40 at $200-250, which reflects the important limitation in installation due to the active/passive cooling.

The K40 has 12GB of memory, 2,880 CUDA cores with single precision of 4.29 TFLOPS and double preicision of 1.43 TFLOPS Of course, the K6000 has more than 2X the memory of teh P2000, which is significant. That is not a large improvement on the Quadro P2000 5GB which is about $430 new and has a 3D average of 7435. The K6000 has 12GB memory, 2,880 CUDA cores with single precision of 5.2TFLOPS and double preicision of 1.7TFLOPS. How are you using the K6000 and K40 currently?Ĭonsidering the high degree of impractility and probabl high the cost of an external cooler- at least $400 and the number of generations that Kepler is obsolete, consider three alternateves: one, a pair of Quadro K6000's- only one needed to purchase- so as to avoid the cooling problem, two, a pair of Quadro P4000 8GB, and three, the recently released NVIDIA Quadro RTX 4000 8GB. Pending for use with a z620, I have an Alphacool Eiswand external unit which is uprated and that was $314 for the raidator /reservoir / pump/fans + $167 for the CPU waterblock, connector and tubing.

If there is a waterblock for the K40 or one could be adapted and if that could be tied into an open loop water cooling system- that would have to be an external unit. These are both Kepler which is important for a Quadro + Tesla configuration and the 1000W PSU should support the power requirements, but the K40 was designed for a server environment with extremely high air flow and dedicated expansion slot air cooling. Using a Quadro K6000 + Tesla K40 is not practical in a Z4 G4.
