NVIDIA Quadro 4000

Launched in late 2010 for the professional workstation market, the NVIDIA Quadro 4000 is a Fermi-architecture card built on TSMC's 40 nm process. With 3,100 million transistors on a 529 mm² die, this single-slot card was designed for CAD, DCC, and scientific visualization. Benchmark results place it at the 28th percentile of all GPUs, indicating that while it is far from modern performance levels, it remains a functional entry point for legacy professional workloads. The following analysis examines its position against direct contemporaries, its feature set, and the practical implications of its specifications.

How It Compares

The Quadro 4000's closest rival is the AMD Radeon HD 8670M, which averages 5,012 points in Geekbench OpenCL. The Quadro trails by a mere 0.2%, a statistically negligible margin. This effectively places the two cards at performance parity, despite the Quadro being a desktop workstation part and the Radeon being a mobile chip. The data suggests that in raw compute throughput, the architectural advantages of Fermi have been fully eroded by the efficiency of younger mobile silicon.

Against the AMD Radeon R5 M430, the Quadro 4000 holds a 0.4% lead, with the Radeon scoring 4,981. This is another near-identical result, reinforcing the notion that the Quadro 4000's compute capability sits in a very narrow band around the 5,000-point mark. The delta is small enough to be considered noise, yet it consistently favors the Quadro by a hair.

The AMD Radeon R7 M360 also scores 4,978, putting the Quadro 0.4% ahead. This pattern of sub-1% margins across all rivals indicates that the Quadro 4000 is not meaningfully faster or slower than any of these parts; it simply occupies the same performance tier. The consistency of these results is notable, as it suggests a performance ceiling shared across architectures and market segments.

The Intel HD Graphics 630, an integrated solution, scores 4,977, with the Quadro leading by 0.5%. This is the largest margin in the rival group, yet it remains trivial in absolute terms. The implication is that a modern integrated GPU can match a professional workstation card from 2010 in OpenCL compute, which underscores how far the low end has advanced.

Ray Tracing and Feature Set

The Quadro 4000 is built on the Fermi architecture and contains no dedicated ray tracing cores and no tensor cores. Its feature set is rooted in the compute and graphics capabilities of 2010-era GPUs. The card supports DirectX 12 (11_0) and OpenGL 4.6, providing broad API compatibility for legacy applications. Vulkan support is absent, which limits its usefulness in modern cross-platform titles and compute frameworks that rely on this API.

The absence of hardware ray tracing means that any ray-traced workloads would fall back to compute shaders, a method that is significantly slower and not supported in most professional applications of the era. For users evaluating this card today, the lack of RT and tensor cores is a fundamental limitation, as modern rendering pipelines and AI-accelerated tasks cannot leverage any specialized hardware. The card's professional positioning at launch relied on certified drivers and ECC memory, though the latter is not specified in the data, rather than on hardware-accelerated novel features.

Display output is limited to 1x DVI and 2x DisplayPort, which is adequate for multi-monitor workstation setups but lacks modern connectivity options like HDMI 2.1 or USB-C. The bus interface is PCIe 2.0 x16, which is backward compatible with modern slots but offers lower bandwidth than PCIe 4.0 or 5.0, potentially bottlenecking data transfers in memory-intensive tasks.

Benchmark Performance

In Geekbench OpenCL, the Quadro 4000 scores 5,000 points. This places it at the 28th percentile of all GPUs, meaning 72% of tested devices perform better. The data shows a tightly clustered rival group, with all four competitors within a 35-point range (4,977 to 5,012). The Quadro's position is essentially dead center of this cluster.

The deltaPct values reveal the narrow margins: -0.2% against the Radeon HD 8670M, and +0.4% against both the R5 M430 and R7 M360, and +0.5% against the Intel HD 630. These are not meaningful performance differences in real-world terms; they are within run-to-run variance. The takeaway is that the Quadro 4000 offers compute performance indistinguishable from these rivals, which is a sobering result for a card that was once a high-end workstation product.

The texture rate is 15.20 GTexel/s, and the pixel rate is 7.600 GPixel/s, figures that were competitive in 2010 but are now dwarfed by integrated graphics. The FP32 throughput of 486.4 GFLOPS is the headline compute number, yet it translates to only a 5,000 OpenCL score, confirming that modern drivers and architectures extract far more performance per FLOP. For professional workloads that rely on OpenCL, this card will struggle with modern datasets, but it remains usable for lightweight or legacy tasks.

Who Should Consider It

Given its 28th percentile ranking and OpenCL score of 5,000, the Quadro 4000 is only suitable for users with very specific legacy needs. At 1080p resolution, the card can handle older CAD applications and 2D design work, where pixel rate and texture rate are sufficient. However, for any modern 3D rendering or simulation at 1080p, the performance will be marginal.

At 1440p or higher, the 2 GB GDDR5 memory and 89.86 GB/s bandwidth become a significant bottleneck. The data suggests that users attempting high-resolution professional visualization will see severe frame rate drops and long computation times. The card is best suited for secondary display output, basic office productivity, or running software that requires a Quadro-certified driver but has minimal GPU demands.

Enthusiasts building a retro workstation or testing legacy Fermi-era software may find value, provided they accept the 28th percentile performance. It is not viable for gaming, as modern titles require more VRAM and higher compute throughput. The 0.5% lead over Intel HD Graphics 630 demonstrates that even the most basic modern iGPU matches this card, so users with any newer hardware already have equivalent or better performance.

Memory Subsystem

The Quadro 4000 is equipped with 2 GB of GDDR5 memory, a capacity that was generous in 2010 but is now considered minimal. The 256-bit memory interface provides a bandwidth of 89.86 GB/s, which is derived from a memory clock of 702 MHz (2.8 Gbps effective). This bandwidth is a critical limiting factor for high-resolution workloads, as modern GPUs typically exceed 200 GB/s even at the entry level.

For professional applications that handle large textures, point clouds, or scientific datasets, the 2 GB capacity will cause frequent out-of-memory errors or forced fallbacks to system memory, which severely impacts performance. At 1080p, the bandwidth is adequate for simple CAD and 2D tasks, but at 1440p or 4K, the data throughput becomes a bottleneck. The pixel rate of 7.600 GPixel/s and texture rate of 15.20 GTexel/s are also constrained by this memory subsystem, meaning that fill-rate-bound operations will see diminishing returns as resolution scales.

The 89.86 GB/s figure places the Quadro 4000 in the same league as the integrated graphics in its rival group, which is why the benchmark scores are so closely clustered. Users requiring large memory pools for GPU compute should look elsewhere, as this card's memory subsystem was designed for a different era of workstation software.

Power and Cooling

The Quadro 4000 has a thermal design power (TDP) of 142 W, which is modest by modern standards but notable for a single-slot card of its generation. The suggested power supply is 300 W, a figure that is easily met by virtually any contemporary PSU, but the requirement for a single 6-pin power connector must be checked against available cables. The card's physical dimensions are 241 mm in length (9.5 inches), 111 mm in height (4.4 inches), and 20 mm in width (0.8 inches), fitting it into a single-slot bracket.

Cooling is handled by a blower-style cooler, as implied by the single-slot design, which exhausts hot air outside the chassis. This is beneficial for multi-GPU or densely packed systems. The 142 W TDP means that the card does not require exotic cooling, and a standard case fan configuration should suffice. Given its end-of-life status, thermal performance may degrade over time due to dried thermal paste, but the low power draw keeps temperatures manageable.

The power connector requirement of 1x 6-pin is straightforward, and the 300 W PSU recommendation suggests this card is not power-hungry. For users integrating this into a modern system, the main consideration is not power delivery but rather the PCIe 2.0 interface, which is older and slower than current standards. The data indicates a modest power footprint, making it an easy addition to any system with a free 6-pin connector and a single slot.
