AMD FirePro W2100 vs NVIDIA Quadro K2000D Comparison

The AMD FirePro W2100 and NVIDIA Quadro K2000D are both end-of-life professional workstation graphics cards built on a 28 nm process at TSMC, but they represent fundamentally different design philosophies from their respective manufacturers. The data shows a narrow but decisive victory for the AMD card in the only benchmark where both were tested, yet the architectural specifications tell a more complex story about where each card's strengths genuinely lie.

Head-to-Head Benchmarks

The sole direct comparison available in the benchmark database is the Geekbench OpenCL test, and the results are surprisingly close. The AMD FirePro W2100 scores 4093 points, while the NVIDIA Quadro K2000D trails with 3919 points, giving AMD a 4.4% advantage. This is not a landslide victory, but it is a consistent one — the delta falls well outside the noise margin seen in the nearest-rival comparisons for either card.

Context matters here. The FirePro W2100's average benchmark score of 4295 places it at the 25th percentile of all GPUs, while the Quadro K2000D's average of 3919 lands at the 23rd percentile. Both are firmly entry-level professional cards, but the AMD part sits slightly higher in the overall distribution. The FirePro's nearest rivals include the NVIDIA GeForce GTX 460M (4282, +0.3%) and the AMD Radeon Vega 3 (4268, +0.6%), while the Quadro K2000D's closest competitor is the NVIDIA Quadro 2000D (3930, -0.3%). The head-to-head delta of 4.4% is actually larger than any of the deltas between either card and its nearest rivals, which suggests the performance gap between these two specific products is more meaningful than their respective positions in the broader GPU landscape.

Interestingly, the FirePro W2100 also has a Geekbench Vulkan score of 4497, a test that was not run on the Quadro K2000D. This additional data point, combined with its higher OpenCL score, gives the AMD card a clear edge in compute-oriented workloads. The Quadro K2000D, meanwhile, has no countervailing benchmark victory — the wins column reads 1 for AMD and 0 for NVIDIA. The data is unambiguous: on raw compute benchmarks, the FirePro W2100 outpaces the Quadro K2000D by a measurable margin.

Where Each One Wins

The benchmark results point to a clear winner for general compute tasks, but the specification sheets reveal that each card has its own domain of superiority. The AMD FirePro W2100 wins on compute efficiency and modern API support. Its OpenCL score of 4093 beats the Quadro's 3919, and its Vulkan implementation (1.2.170) is nearly on par with NVIDIA's (1.2.175). The FirePro also supports DirectX 12 (11_1) versus the Quadro's DirectX 12 (11_0), a minor but real difference for compatibility with newer applications.

The NVIDIA Quadro K2000D wins on raw throughput and memory bandwidth. Its 64.00 GB/s of memory bandwidth is more than double the FirePro's 28.80 GB/s, thanks to GDDR5 memory running at 4 Gbps effective versus the FirePro's DDR3 at 1800 Mbps effective. The Quadro also has more shading units (384 vs 320), more texture mapping units (32 vs 20), and more raster output units (16 vs 8). These hardware advantages translate into higher theoretical rates: the Quadro delivers 30.53 GTexel/s and 7.632 GPixel/s, while the FirePro manages 13.60 GTexel/s and 5.440 GPixel/s. For texture-heavy rendering or fill-rate-bound operations, the Quadro K2000D should be noticeably faster despite its lower compute benchmark score.

The FirePro W2100, however, counters with a lower power draw (26 W vs 51 W) and a smaller physical footprint (168 mm vs 202 mm length). It also uses a PCIe 3.0 x8 interface versus the Quadro's PCIe 2.0 x16 — the newer standard may offer better bandwidth efficiency even with fewer lanes, though the Quadro's higher raw bandwidth could offset this in practice.

Architecture Differences

The two cards come from different architectural generations and design philosophies. The AMD FirePro W2100 uses the Oland chip based on GCN 1.0 architecture, part of the FirePro GCN (Wx100) generation. It packs 950 million transistors into a 77 mm² die, achieving a transistor density of 12.3 million per square millimeter. The NVIDIA Quadro K2000D uses the GK107 chip with Kepler architecture, belonging to the Quadro Kepler (Kx000) generation. It houses 1,270 million transistors on a 118 mm² die, with a slightly lower density of 10.8 million per square millimeter.

Memory configurations differ significantly. Both cards have 2 GB of memory and a 128-bit bus width, but the type and speed diverge sharply. The FirePro uses DDR3 at 900 MHz (1800 Mbps effective), yielding 28.80 GB/s of bandwidth. The Quadro uses GDDR5 at 1000 MHz (4 Gbps effective), achieving 64.00 GB/s — more than double the AMD card's bandwidth. This is the single largest architectural advantage for NVIDIA.

Compute resources also favor NVIDIA in raw counts. The Quadro's 384 shading units, 32 TMUs, and 16 ROPs compare favorably to the FirePro's 320 shading units, 20 TMUs, and 8 ROPs. The FP32 throughput reflects this: 732.7 GFLOPS for the Quadro versus 435.2 GFLOPS for the FirePro. Neither card has dedicated ray tracing or tensor cores.

Clock speeds tell a different story. The FirePro has a base clock of 630 MHz and a boost clock of 680 MHz, while the Quadro's base and boost clocks are not specified in the data. The FirePro's modest clocks, combined with its low 26 W TDP, suggest a design focused on efficiency rather than peak performance. The Quadro's 51 W TDP and unspecified clocks indicate it has headroom for higher operating frequencies, though the benchmark results suggest this does not translate into better OpenCL performance.

Display outputs differ as well. The FirePro offers 2x DisplayPort 1.2, while the Quadro provides 2x DVI and 1x mini-DisplayPort 1.2. The bus interfaces are also different: PCIe 3.0 x8 on the AMD side versus PCIe 2.0 x16 on the NVIDIA side. Both cards are end-of-life, with the FirePro released later (August 2014) than the Quadro (February 2013). The AMD card's predecessor is FirePro Terascale and its successor is Radeon Pro Polaris; the NVIDIA card's predecessor is Quadro Fermi and its successor is Quadro Maxwell.

The Verdict

The benchmark data is clear: the AMD FirePro W2100 wins the only direct comparison, posting a 4.4% higher OpenCL score than the NVIDIA Quadro K2000D. It also offers lower power consumption (26 W vs 51 W), a more compact physical design, and slightly newer API support. For users whose primary workload is OpenCL-based compute — simulation, analysis, or general-purpose GPU computation — the FirePro W2100 is the better choice based on measured performance.

However, the Quadro K2000D is not without its own case. Its GDDR5 memory with 64.00 GB/s of bandwidth, double the FirePro's 28.80 GB/s, combined with higher texture and pixel fill rates, suggests it would outperform the AMD card in bandwidth-sensitive tasks such as large texture loads or high-resolution 2D rendering. The Quadro also has more shading units (384 vs 320) and higher theoretical FP32 throughput (732.7 GFLOPS vs 435.2 GFLOPS), which could matter in applications that are not well-represented by the OpenCL benchmark.

The choice ultimately depends on workload type. For compute-heavy tasks measured by OpenCL and Vulkan benchmarks, the AMD FirePro W2100 is the data-backed winner. For tasks that benefit from raw memory bandwidth and fill rates — and where the 51 W power draw is acceptable — the NVIDIA Quadro K2000D offers theoretical advantages that the benchmark does not capture. Users prioritizing efficiency, modern API support, and measured compute performance should favor the FirePro W2100. Those who need maximum memory bandwidth and texture throughput in a single-slot professional card may find the Quadro K2000D more suitable, despite its lower benchmark score.
