Nvidia Quadro K2000

Of course, not all of Nvidia’s latest professional graphics cards are based on the GK104 chip. The company has cheaper GPUs, GK106 and GK107, which are used on Quadro series products, too. One of them is the Quadro K2000 model, which features the GK107 chip. The GPU works in its full configuration without any disabled subunits, which makes the Quadro K2000 the professional counterpart of the gaming GeForce GTX 650 model. Their GPUs incorporate 384 unified shader processors, 32 texture-mapping units and 16 raster operators. The K2000’s GPU clock rate is rather high at 954 MHz, so the fill rate is 15.3 Gpixel/s while the texture sampling rate is 30.5 Gtexel/s. That’s not so bad in comparison with the K4000, which is only 30% faster, at least theoretically. The Quadro K2000 is rather weak in the computing department, having a small number of CUDA processors, but, as we've mentioned above, it is hardly a serious downside for a professional card designed for 3D CAD/CAM applications.

The Nvidia Quadro K2000 is equipped with a standard 2 gigabytes of GDDR5 memory which is clocked at 5.0 GHz. Coupled with the 128-bit bus, the peak memory bandwidth is 64.0 GB/s.

Professional graphics cards try to avoid dual-slot coolers because graphics workstations usually have much more expansion cards than home computers. Compactness is valuable there. That’s why the Quadro K2000 is equipped with a flat and slim cooler. It uses a centrifugal blower, just like coolers of high-performance cards, but it is small because the GK107 chip has rather low heat dissipation. The cooler doesn’t even cover the entire PCB, so it cannot exhaust the hot air out of the computer case.

The cooler’s fan doesn’t accelerate to high speeds, making the card rather quiet. The K2000 is also economical with a peak power draw of only 51 watts, so it doesn’t have an additional power connector.

The Quadro K2000 has the same video outputs as the K4000: two DisplayPorts and one DVI-I. By the way, the new professional product series with Kepler architecture is overall better than their predecessors in terms of multi-monitor configurations. Even the K2000 supports up to four monitors simultaneously (via an MST hub) and stereo 3D functionality (via USB).

The Quadro K2000 comes at a rather low price of $430, offering a very appealing combination of performance, power consumption, and cost.
