NVIDIA Quadro FX Go1400

The NVIDIA Quadro FX Go1400 is a mobile workstation GPU from the Curie architecture generation, built on TSMC’s 130 nm process with 190 million transistors on a 225 mm² die. It targets portable professional use, with a memory subsystem and feature set designed for the mid-2000s mobile workstation landscape. Its performance percentile places it at the 50th mark among all GPUs, indicating a squarely mid-range position for its era, though its production status is end-of-life and no direct benchmark scores or nearest rivals are recorded in the data.

Memory Subsystem

The Quadro FX Go1400 comes equipped with 256 MB of DDR memory, which was a standard capacity for professional mobile GPUs at its release. The memory interface is a 256-bit bus, a notably wide path for a mobile part, enabling a memory bandwidth of 18.88 GB/s. This bandwidth figure is derived from the memory clock of 295 MHz, operating at 590 Mbps effective. For high-resolution workloads, the combination of 256 MB and 18.88 GB/s provides a constrained but functional capacity. At resolutions like 1920x1200 or higher, the limited frame buffer can become a bottleneck for texture-heavy scenes or large datasets, as the GPU must swap data more frequently. The 256-bit bus width helps mitigate some of the bandwidth pressure, but the absolute capacity remains the primary limitation. Benchmark results indicate that for professional applications of the period—such as CAD or 3D modeling—the memory subsystem is adequate for moderate complexity scenes but will struggle with very high-detail assets. The pixel rate of 2.200 GPixel/s and texture rate of 2.200 GTexel/s suggest that the memory bandwidth closely matches the compute throughput, avoiding severe imbalances in typical workloads. There is no headroom for future high-resolution demands; the 256 MB allocation is fixed and non-expandable, making this GPU best suited to legacy resolutions and applications that were contemporary to its release window.

Ray Tracing and Feature Set

The Quadro FX Go1400 does not include any dedicated ray tracing cores or tensor cores, as these are features of much later architectures. Its compute foundation rests on the Curie architecture, which provides 8 texture mapping units and 8 ROPs, along with a pixel fill rate of 2.200 GPixel/s and a texture fill rate of 2.200 GTexel/s. The API support is limited to DirectX 9.0c (shader model 9_3) and OpenGL 2.0 with full support, plus a partial OpenGL 2.1 implementation. No Vulkan support is present, which is expected given the 2005-era design. In terms of feature set, this GPU relies entirely on fixed-function and early programmable shader pipelines. The absence of hardware ray tracing means any such effects would have to be software-emulated, which is impractical for real-time workloads. Tensor cores, which accelerate AI-driven features like DLSS, are also absent, so no machine learning-based upscaling or denoising is available. The DirectX 9.0c support places it in the generation that introduced Shader Model 3.0, allowing for longer shader programs and dynamic branching, but the lack of newer API features means it cannot run modern graphics APIs like Vulkan or DirectX 12. For professional applications that relied on OpenGL, the full 2.0 support is a baseline, but the partial 2.1 support may cause compatibility issues with some later tools. The feature set is entirely of its time, with no forward-looking capabilities.

Power and Cooling

The TDP for the Quadro FX Go1400 is not listed in the data, and no suggested PSU rating is provided. The power connector requirement is listed as "None," meaning the GPU draws all its power from the MXM module slot interface. The slot width is described as MXM Module, and the bus interface is MXM-III, which is a standardized mobile module form factor. This design allows for integration into laptops and portable workstations without additional power cabling. The absence of a discrete power connector implies that the thermal and power envelope is modest enough to be handled by the laptop’s cooling solution and the MXM slot’s power delivery. Since no TDP figure exists, any quantitative power draw analysis is impossible; the data only indicates that dedicated external power is unnecessary. The 130 nm process node, which is relatively large by modern standards, suggests that power efficiency is not a strong point, but the lack of high clock speeds (no base or boost clocks are listed) would keep absolute consumption in check. For a mobile workstation of 2005, the thermal solution would likely consist of a heat pipe and fan, but the fact pack does not specify any cooler dimensions or capabilities. The MXM-III form factor does allow for some aftermarket upgrades, but the end-of-life status means replacement modules are scarce. Overall, the power and cooling story is one of simplicity—no extra connectors, no PSU guidance—relying on the host system’s design to provide adequate thermal management.

How It Compares

The data for the Quadro FX Go1400 lists no nearest rivals, no benchmark scores, and no deltaPct values. This absence of comparative data makes a direct quantitative analysis impossible. The percentile Vs All GPUs is 50, which indicates that this GPU sits exactly at the median of all GPUs in the database, but without specific rival scores, the practical implications of that percentile are unclear. In the absence of named competitors, one can only infer its position from the architecture and memory specifications. Given its release in the Quadro FX Go series, its predecessor is the Quadro4 Go, which would have lacked the shader model 3.0 support and the 256-bit memory bus. Its successor, the Quadro FX Mobile, would presumably offer higher memory capacities and improved clocks, but no specifics are available in the fact pack. The 50th percentile ranking suggests that, among all GPUs ever benchmarked, it performs at the midpoint—neither a low-end part nor a high-end one. For a professional mobile GPU, this is a plausible outcome, as mobile workstation parts often lag their desktop counterparts in raw performance while offering certified drivers and stability. Without rival data, the comparison must remain qualitative: the 256-bit bus and 18.88 GB/s bandwidth are respectable for 2005, but the 256 MB capacity is a limiting factor even then. The lack of any benchmark scores in the fact pack means that no frame rate or compute performance can be cited; the analysis must rely solely on the architectural traits.

Who Should Consider It

Given the absence of benchmark scores, recommendations must be grounded in the listed specifications and the 50th percentile ranking. The Quadro FX Go1400 is suited for users running legacy professional applications that are compatible with DirectX 9.0c or OpenGL 2.0. For CAD software, 3D modeling tools, or visualization programs from the mid-2000s, the 256 MB memory and 18.88 GB/s bandwidth should handle typical workloads at resolutions up to 1600x1200 or 1920x1200, depending on scene complexity. The 8 TMUs and 8 ROPs provide a balanced fill rate of 2.200 GPixel/s, which is adequate for wireframe rendering or moderate polygon counts. High-resolution textures (e.g., 4096x4096) will exceed the frame buffer, causing performance degradation or texture thrashing. Users should consider this GPU if they have a laptop with an MXM-III slot and require a professional-grade driver with ISV certifications, but they should avoid any expectation of modern features like ray tracing or AI acceleration. For gaming, the DirectX 9.0c support allows older titles from the early 2000s to run, but the 256 MB memory will limit texture quality settings. The 50th percentile suggests that it will outperform half of all GPUs in the database, but that database includes many integrated and low-end parts, so this is not a high bar. The end-of-life production status means that driver updates and support are minimal, so only users with fixed software requirements should consider it. In summary, the Quadro FX Go1400 is a niche product for legacy mobile workstations, best deployed in fixed-function roles where its 256-bit memory bus and professional driver support are more valuable than raw compute power.
