Quadro4 400 NVS PCI Benchmark Scores
No benchmark data available for this GPU.
About NVIDIA Quadro4 400 NVS PCI
The NVIDIA Quadro4 400 NVS PCI is a legacy workstation adapter built on the Celsius architecture, and its benchmark data places it at the 50th percentile among all GPUs, with an average benchmark score of 0. This positioning indicates that it is not a performance-oriented part by modern standards, but rather a functional, low-power display solution from an earlier era. The data shows a GPU designed for basic 2D output and multi-monitor setups, not for compute or high-end graphics workloads.
Benchmark Performance
The Quadro4 400 NVS PCI records an average benchmark score of 0, which places it at exactly the 50th percentile of all GPUs in the database. This percentile ranking is a statistical midpoint, but in real terms, a score of 0 means the card produces no measurable performance in the current benchmark suite. The card’s pixel rate is 440.0 MPixel/s, and its texture rate is 880.0 MTexel/s. These figures are extremely low compared to any modern GPU, and they reflect the card’s age and intended role. The pixel rate of 440.0 MPixel/s suggests it can handle basic desktop composition and 2D acceleration, but any 3D workload will be severely limited. The texture rate of 880.0 MTexel/s reinforces this, as even entry-level integrated graphics from the past decade outperform this by orders of magnitude.
Because the nearestRivals array is empty, there are no direct percentage deltas to report against competing products. However, the absence of rival data combined with a score of 0 suggests that the card is not competitive in any compute or gaming scenario. The benchmark results indicate that this GPU is best understood as a display adapter rather than a processing unit. Its 50th percentile ranking is misleading without context; it does not mean the card is average in capability, but rather that half of all GPUs in the database score below zero (which is impossible) or that the scoring system normalizes non-performing parts to this midpoint. In practice, a score of 0 means no meaningful workload was completed.
Power and Cooling
The Quadro4 400 NVS PCI has a thermal design power (TDP) of just 18 W. This is an exceptionally low figure, and it means the card generates minimal heat. The data shows that the card requires no power connectors, drawing all its power from the PCI slot itself. A suggested power supply of 200 W is specified, which is very modest by current standards, but this recommendation likely accounts for the rest of the system’s components rather than the card alone. The card is single-slot in design, which is typical for a low-profile workstation adapter. Cooling requirements are minimal; a passive heatsink or a small fan would suffice, though the fact pack does not list specific cooler dimensions or types. The 18 W TDP means the card will not stress even an older or lower-wattage power supply, and its lack of power connectors simplifies installation in almost any desktop system.
Ray Tracing and Feature Set
The Quadro4 400 NVS PCI has no ray tracing cores and no tensor cores, as indicated by the null entries in the fact pack. This is not surprising given its 2004 release date and the Celsius architecture, which predates any hardware acceleration for ray tracing by nearly two decades. The card supports DirectX 7.0 and OpenGL 1.5, both of which are ancient API versions. DirectX 7.0 was designed for the GeForce 2 era, and OpenGL 1.5 does not include modern shader capabilities or features like geometry shaders or tessellation. There is no Vulkan support listed, meaning the card cannot run any modern graphics API. The feature set is limited to fixed-function pipeline operations, which were standard for the time. For any ray-traced workload, the card is entirely unsuitable, as it lacks the dedicated hardware and the API support to even attempt such tasks. The absence of tensor cores also rules out any AI or machine learning acceleration.
Who Should Consider It
Given the benchmark score of 0 and the very low pixel and texture rates, this card is only suitable for basic 2D display output. The data suggests that it can drive two LFH60 display outputs, which are legacy connectors used for dual-monitor setups in professional environments. Users who need a simple, low-power card for spreadsheet work, text editing, or legacy software that requires a specific driver environment might find it functional. However, for any 3D application, gaming, or video playback, the card will fail to deliver usable performance. The 440.0 MPixel/s pixel rate translates to a theoretical maximum of about 440 million pixels per second, which is insufficient for even 720p video acceleration in modern codecs. For high resolutions or high refresh rates, the card is not viable. It is best considered for retro systems or as a diagnostic tool, not as a daily driver for any modern workload.
How It Compares
The nearestRivals array is empty, so there are no direct competitor comparisons available in the data. This means the Quadro4 400 NVS PCI has no benchmarked rivals within its class in the current database. The absence of rival data is itself informative; it suggests that the card is so old and low-performing that no other GPU shares a similar benchmark profile. Without rival scores or deltaPct values, any comparative analysis is impossible. The card’s 50th percentile ranking is a placeholder that does not reflect a competitive position; it simply indicates that the scoring algorithm assigns it a midpoint value due to its zero score. In historical context, this card would have competed with other early 2000s workstation GPUs, but those are not listed in the fact pack.
Memory Subsystem
The Quadro4 400 NVS PCI features 64 MB of DDR memory on a 128-bit bus. The memory clock is 166 MHz, with an effective data rate of 332 Mbps. This configuration yields a memory bandwidth of 5.312 GB/s. These specifications are extremely limited by any standard. The 64 MB capacity is insufficient for even low-resolution textures in modern games, and the 5.312 GB/s bandwidth is a fraction of what even entry-level cards from a decade later offered. The 128-bit bus width is respectable for the era, but the low memory clock severely constrains throughput. For high resolutions, this card will quickly run out of memory and bandwidth, causing rendering to fail or become unresponsive. The pixel rate of 440.0 MPixel/s is also tied to memory bandwidth; at 1080p (approximately 2 million pixels per frame), the card can theoretically fill about 220 frames per second, but only if the rest of the pipeline can keep up, which it cannot. In practice, the memory subsystem is a bottleneck, and the card’s performance will degrade rapidly with any increase in resolution or texture detail.
