About NVIDIA Quadro K2000D
The NVIDIA Quadro K2000D is a Kepler-generation professional GPU built on the 28nm GK107 chip. It packs 384 shading units, 32 texture units, and 16 ROPs, paired with 2GB of GDDR5 memory on a 128-bit bus. Its Geekbench OpenCL score of 3919 places it at the 22nd percentile of all GPUs, a modest position for a card that launched on February 28, 2013, with a launch MSRP of 599 USD. The K2000D is now end-of-life, but its specifications still define a clear niche in legacy professional systems. With a TDP of just 51W and no power connectors, it is one of the most power-efficient Quadro cards ever produced, making it a candidate for retrofits into older workstations.
How It Compares
The K2000D's nearest rival is the NVIDIA Quadro K2100M, which scores 3912 in Geekbench OpenCL. The K2000D leads by 0.2%, a margin so small that it falls within run-to-run variance. Both cards share the same Kepler architecture, but the K2100M is a mobile part, while the K2000D is desktop. The K2000D's advantage is likely due to its higher memory bandwidth or slightly different clock behavior, though the data does not specify those details.
Against the AMD Radeon R5 M420, the K2000D again posts a 0.2% advantage, scoring 3919 versus 3911. The R5 M420 is an entry-level discrete GPU, and the near-identical scores suggest that the K2000D offers comparable compute throughput despite its professional branding. This parity is notable because the R5 M420 is a much simpler chip, but the K2000D's Kepler architecture and 384 shading units give it enough compute to match.
The Quadro 2000D is the only rival that beats the K2000D, scoring 3930 — 0.3% higher. This is the direct predecessor in the Quadro lineup, and the small gap indicates that the K2000D did not bring a significant compute uplift over its forebear. The 2000D also uses a similar memory configuration, which explains the close result.
Finally, the K2000D outperforms the NVIDIA Quadro P1000 by 0.5%, with the P1000 scoring 3900. The P1000 is a much newer card based on the Pascal architecture, yet in this OpenCL test, the older K2000D holds a slight edge. This is likely due to driver optimizations or benchmark characteristics, but the data is clear: the K2000D is not a performance outlier in either direction. In fact, all five GPUs in this comparison cluster within 0.5% of each other, making the K2000D a mid-pack performer in its immediate peer group.
Power and Cooling
The Quadro K2000D is rated for a 51W TDP, which is exceptionally low for a professional GPU. It requires no auxiliary power connectors, drawing all its power from the PCIe 2.0 x16 slot. The suggested PSU is 250W, making it suitable for small form-factor or legacy systems with limited power budgets. The card is a single-slot design, measuring 202mm in length and 111mm in height. Its 28nm process, manufactured by TSMC, packs 1,270 million transistors into a 118 mm² die, yielding a transistor density of 10.8 million per mm². This efficiency is a hallmark of the Kepler architecture, allowing the card to deliver 732.7 GFLOPS of FP32 performance while drawing only 51W. The memory subsystem uses GDDR5 at 1000 MHz (4 Gbps effective) across a 128-bit bus, providing 64 GB/s of bandwidth. That bandwidth is modest, but it is sufficient for the card's intended professional workloads. Display outputs include 2x DVI and 1x mini-DisplayPort 1.2, which covers legacy and modern monitors alike. The production status is end-of-life, so it is no longer in active manufacture. The PCIe 2.0 x16 interface provides adequate data transfer for the card's memory and compute needs.
Benchmark Performance
In Geekbench OpenCL, the K2000D scores 3919, placing it at the 22nd percentile of all GPUs. This is a low standing, meaning the card is outperformed by the vast majority of GPUs in the database. The nearest rivals confirm this tier: the Quadro K2100M scores 3912 (0.2% slower), the Radeon R5 M420 scores 3911 (0.2% slower), the Quadro 2000D scores 3930 (0.3% faster), and the Quadro P1000 scores 3900 (0.5% slower). All five cards are within 0.5% of each other, so the K2000D is effectively tied with its immediate competition. The card's compute capability is further quantified by its FP32 rate of 732.7 GFLOPS, its pixel rate of 7.632 GPixel/s, and its texture rate of 30.53 GTexel/s. These figures align with its 384 shading units, 32 TMUs, and 16 ROPs. The memory bandwidth of 64 GB/s is a limiting factor for large datasets, but the card's API support — DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175 — ensures compatibility with a wide range of software, including modern legacy applications that still rely on these interfaces. The 22nd percentile rank indicates that the K2000D is not a competitive choice for compute-heavy tasks like machine learning or high-end rendering, but it can handle basic geometry and 2D workloads without issue.

Who Should Consider It
The Quadro K2000D is a legacy professional card that, based on its 22nd percentile rank, is not suited for demanding modern workloads. Its 2GB GDDR5 frame buffer and 64 GB/s bandwidth are adequate for basic 2D CAD or older 3D applications, but the 128-bit bus will limit performance in texture-heavy scenes. The card's pixel rate of 7.632 GPixel/s and texture rate of 30.53 GTexel/s suggest it can handle entry-level viewport tasks at typical professional resolutions, though it will struggle with complex shading or high-detail models. For users running legacy software that leverages OpenGL 4.6 or Vulkan 1.2.175, the K2000D offers a stable, low-power (51W) solution that fits in a single slot and requires no extra power connectors. However, given that it is end-of-life and only 0.5% faster than the Quadro P1000 in OpenCL, most buyers should consider the P1000 for its newer architecture and better driver support. The K2000D is best reserved for systems that specifically need its dual DVI outputs or where a 250W PSU is the only option. Its low power draw and single-slot design also make it an easy drop-in replacement for older Quadro Fermi cards, which are its direct predecessors. The 2GB memory capacity is sufficient for 2D drafting and light 3D modeling, but not for high-resolution textures or multi-monitor setups with heavy compositing. In short, the K2000D is a functional, if unremarkable, option for those who need a reliable, low-power professional GPU with legacy connectivity.
