NVIDIA Quadro FX 4000

How It Compares

The NVIDIA Quadro FX 4000 sits in a peculiar position: it is an end-of-life workstation card built on the Curie architecture, using the NV40 chip on a 130 nm process. With no nearest rivals listed in the data, its competitive context must be inferred from its own specifications and its 50th percentile standing among all GPUs. That percentile places it exactly in the middle of the pack — not a top-tier performer, but not a bottom-feeder either. For a 2004-era professional card, this means it was a solid mid-range workstation option, though modern comparisons are largely academic given its age.

The card’s predecessor, the Quadro4 Celcius, and its successor, the Quadro FX Curie, bracket its generation, but the FACT PACK provides no scores for either. Without rival benchmark numbers, the only quantitative anchor is the percentile rank. A 50th percentile score indicates that half of all GPUs in the database perform better, and half perform worse — a balanced, unremarkable position. In practical terms, the Quadro FX 4000 was neither a flagship nor a budget part; it occupied the middle ground where many professional users found adequate performance for CAD and DCC workloads of its time.

Who Should Consider It

Based on the specifications, the Quadro FX 4000 targets users working with legacy professional applications rather than modern gaming or compute tasks. The card offers 256 MB of GDDR3 memory on a 256-bit bus, yielding 32.00 GB/s of bandwidth. That memory capacity is small by any modern standard, so it suits only older, low-texture workloads or 2D-heavy tasks. At resolutions common in 2004 — typically 1024x768 or 1280x1024 — the card’s 6.000 GPixel/s pixel rate and 6.000 GTexel/s texture rate would handle early DirectX 9.0c titles and OpenGL 2.0-era professional apps competently. However, pushing beyond those resolutions or enabling high-detail settings would quickly exhaust the 256 MB frame buffer.

For users running legacy industrial software that relies on OpenGL 2.0.3 (full) or 2.1 (partial) support, the Quadro FX 4000 offers certified compatibility. Its dual DVI and S-Video outputs also make it viable for multi-monitor workstation setups, provided those displays are from the same era. Gamers, even those playing older titles, would find the card limiting at higher resolutions. The data suggests a clear recommendation: this is a card for retro workstation builds, not for modern gaming or content creation.

Power and Cooling

The Quadro FX 4000 has a thermal design power of 142 W, which is modest by today’s standards but was substantial for a single-slot AGP card in 2004. The manufacturer recommends a 300 W power supply, a figure that assumes a typical period-correct system with a single CPU and a few drives. The card requires two Molex power connectors, which is an unusual requirement for a GPU — most modern cards use PCIe power plugs, but the AGP 8x interface could not supply sufficient power on its own. Builders must ensure their power supply has two available Molex connectors, which may require adapters in modern systems.

The card’s single-slot design means it exhausts heat through a standard bracket, and its 214 mm length (8.4 inches) and 111 mm height (4.4 inches) make it compatible with most ATX cases of its generation. Given the 142 W TDP, a capable air cooler is sufficient — no exotic liquid cooling or oversized heatsink is necessary. The 300 W PSU recommendation is a hard floor, not a suggestion; running this card with a weaker supply risks instability or damage. For a retro build, a modern 400-500 W PSU with two Molex adapters would provide ample headroom, though the FACT PACK does not specify any modern PSU guidance beyond the 300 W figure.

Benchmark Performance

The FACT PACK lists no benchmark scores for the Quadro FX 4000, and its nearestRivals array is empty, so no direct percentage comparisons can be made against other GPUs. The only quantitative performance indicator is the percentileVsAllGpus value of 50, which places the card at the exact median of all GPUs in the database. This is a neutral result: the card is neither a standout performer nor a laggard. For a professional card from 2004, this likely reflects its balanced design — 16 TMUs and 16 ROPs are modest figures, but they align with the pixel and texture rates of 6.000 GPixel/s and 6.000 GTexel/s.

The absence of rival scores means the card’s performance must be interpreted through its architectural traits. The NV40 chip packs 222 million transistors on a 287 mm² die, produced on TSMC’s 130 nm process, giving a transistor density of 773.5K per mm². That density is low by modern standards, but it was competitive for its era. The memory subsystem, with 32.00 GB/s of bandwidth, is the likely bottleneck in any workload exceeding simple geometry. Benchmark results from the period (not in the FACT PACK) would show the card trailing the high-end Quadro FX Curie successors, but the data here only supports the 50th percentile claim. Users should expect mid-pack performance — acceptable for early-2000s professional apps, but not for anything demanding modern shader complexity or large textures.

Memory Subsystem

The Quadro FX 4000’s memory subsystem is defined by three key figures: 256 MB of GDDR3, a 256-bit bus, and 32.00 GB/s of bandwidth. The memory clock is 500 MHz, translating to 1000 Mbps effective due to double data rate transfer. This configuration was standard for high-end cards in 2004, but it severely limits the card in modern contexts. The 256 MB capacity is the most restrictive element — modern games routinely require 4-8 GB, and even professional 3D scenes with high-resolution textures will exceed 256 MB quickly. The 256-bit bus width, however, is a positive trait; it provides a balanced path for data flow, and the resulting 32.00 GB/s bandwidth is respectable for the memory clock.

For high resolutions — say, 1600x1200 or above — the 256 MB frame buffer becomes a hard ceiling. At those settings, the card would need to swap textures in and out of system memory via the AGP 8x bus, which would cause stuttering and reduced frame rates. The 6.000 GPixel/s pixel rate can fill a 1600x1200 screen roughly 3.1 times per second (not in the FACT PACK, but derived from the pixel rate and resolution math), but the memory capacity would choke before that theoretical limit is reached. For 1024x768 or 1280x1024, the 256 MB buffer is more workable, especially with reduced texture quality. The GDDR3 memory type is an upgrade over the older DDR2 used in some rivals, but the small capacity negates that advantage in practice. In summary, the memory subsystem is balanced for its era but fundamentally undersized for any modern workload, making the Quadro FX 4000 a niche part for retro builds and legacy software only.
