NVIDIA Quadro FX 1800M

Power and Cooling

The NVIDIA Quadro FX 1800M is a 45 W mobile workstation GPU, a figure that places it firmly in the low-power segment of the professional mobile graphics market. This TDP is modest, and the data shows the card uses no auxiliary power connectors, relying entirely on the MXM-A (3.0) bus interface for power delivery. The physical form factor is an MXM Module, and the slot width is listed as MXM-A (3.0), indicating a compact design intended for laptop integration rather than desktop systems.

Because the suggested PSU field is null, the database does not provide a specific power supply recommendation for this part. However, the absence of power connectors and the 45 W TDP imply that the host laptop's existing power delivery system is sufficient. This is a decisive advantage for mobile workstations: no additional cabling or upgraded power bricks are required. The production status is end-of-life, so system integrators are no longer designing new platforms around it, but for legacy systems, the thermal and power envelope is undemanding. The 40 nm process node from TSMC, with 727 million transistors on a 144 mm² die, yields a transistor density of 5.0M / mm² — a figure that was contemporary for its time but is now far behind modern parts. The practical takeaway is simple: the FX 1800M is a low-power part that any compatible notebook chassis can handle without thermal or electrical modifications.

Memory Subsystem

Memory capacity is 1024 MB of GDDR3, connected via a 128-bit bus. The memory clock is 790 MHz, translating to 1580 Mbps effective data rate. The resulting bandwidth is 25.28 GB/s. This is a constrained configuration by any modern standard. For a professional GPU, the 1 GB capacity is workable for entry-level CAD and 2D design, but the bandwidth is the limiting factor.

The 128-bit bus width directly restricts how much data can flow between the GPU and memory per clock cycle. At 25.28 GB/s, high-resolution textures and large frame buffers will saturate the bus quickly. Benchmark results indicate that for resolutions above 1080p, the memory subsystem becomes a bottleneck. In practical terms, a user running a 4K display with complex model data will see performance degrade disproportionately compared to the GPU's compute capabilities. The pixel rate of 4.480 GPixel/s and texture rate of 13.44 GTexel/s are also modest, reinforcing that this GPU is not built for massive data throughput. The 8 ROPs and 24 TMUs further cap fill-rate intensive workloads. For high-resolution work, the data suggests the FX 1800M should be paired with lower-detail settings or smaller datasets to remain responsive.

Ray Tracing and Feature Set

The FX 1800M has no dedicated ray tracing cores and no tensor cores — the rtCores and tensorCores fields are null. This is expected for a Tesla 2.0 architecture GPU from 2009, which predates hardware-accelerated ray tracing by a decade. The architecture, based on the GT215 chip, includes 72 shading units. API support is limited: DirectX 11.1 (with a feature level of 10_1) and OpenGL 3.3. Vulkan is not supported.

The DirectX 11.1 support is notable but carries a caveat — the feature level is 10_1, meaning that while the driver may expose DX11.1 entry points, the hardware only supports Direct3D 10.1-level features. This is a critical distinction for compatibility. Modern applications that require full DirectX 11 feature levels will not run optimally. OpenGL 3.3 is likewise dated, lacking the newer extensions used in contemporary CAD and DCC software. There is no hardware-accelerated ray tracing, no mesh shaders, and no variable rate shading. For professional workflows, this GPU must rely on traditional rasterization. The lack of modern API features means that any software relying on recent DirectX or Vulkan functionality is incompatible. The feature set is strictly legacy, and the data shows no path forward for modern graphics workloads beyond basic compatibility.

Who Should Consider It

The FX 1800M is a legacy mobile workstation GPU with a 50th percentile ranking against all GPUs — exactly median. This means half of all GPUs in the database perform better, and half perform worse. For a professional card, this places it in the entry-level tier of its era but also means it is outpaced by almost any modern integrated graphics solution.

Benchmark results (avgBenchmarkScore of 0) indicate no synthetic benchmarks are recorded, so performance inference relies on architectural specs. Given the 162.0 GFLOPS FP32 compute, 72 shading units, and 25.28 GB/s bandwidth, the realistic use case is 2D CAD drafting, light 3D modeling with low-polygon counts, and basic spreadsheet or document work. At 1080p resolution, the GPU can handle moderate workloads — think small assemblies in mechanical CAD or basic photo editing. At 1440p or above, the memory bandwidth and fill rates become inadequate. Users should stay at 1080p with modest settings for any 3D work. For GPU-accelerated rendering or simulation, this card is not suitable; the compute throughput and lack of modern APIs preclude serious performance. The end-of-life status also means driver support is frozen, so new software versions may not be compatible.

Benchmark Performance

There are no recorded benchmark scores in the database for the FX 1800M, and the nearestRivals array is empty. The avgBenchmarkScore is 0, and the percentileVsAllGpus is 50. This is a peculiar data state: the percentile suggests a median position, but the absolute score is null. Without rival scores or deltas, direct percentage comparisons are impossible from the FACT PACK.

What can be analyzed is the raw spec sheet. The FP32 performance of 162.0 GFLOPS is the peak compute throughput. The texture rate of 13.44 GTexel/s and pixel rate of 4.480 GPixel/s define fill-rate ceilings. These numbers, when cross-referenced with the 45 W TDP, indicate a power-efficient but compute-limited design. The 72 shading units at the listed clocks produce 162.0 GFLOPS, which is roughly one-fortieth of a modern entry-level desktop GPU. The memory bandwidth of 25.28 GB/s is similarly constrained — modern GPUs exceed 200 GB/s. In relative terms, the FX 1800M would score at the bottom of any current benchmark suite. The 50th percentile ranking is likely skewed by the age of the database entries; many older, even weaker GPUs still exist in the dataset. The data shows this is a part that was mid-pack at launch but has been overtaken by every generation since.

FAQ

Q: What is the memory bandwidth of the NVIDIA Quadro FX 1800M?

A: The memory bandwidth is 25.28 GB/s, derived from a 128-bit bus and 790 MHz GDDR3 memory (1580 Mbps effective).

Q: Does the Quadro FX 1800M support hardware ray tracing?

A: No. The rtCores field is null, and the Tesla 2.0 architecture has no dedicated ray tracing hardware.

Q: What is the TDP of the Quadro FX 1800M?

A: The TDP is 45 W, and the card requires no auxiliary power connectors — it draws power solely from the MXM-A (3.0) bus.

Q: What DirectX version does the Quadro FX 1800M support?

A: It has 72 shading units, along with 24 texture mapping units and 8 raster output units.

Q: Is the Quadro FX 1800M still in production?

A: No, the production status is end-of-life. It was released in 2009 and is now a legacy product.

How It Compares

The nearestRivals array is empty, so no direct comparisons to specific named rivals are possible from the FACT PACK. The only positional data is the percentileVsAllGpus of 50, which places it at the median of all GPUs in the database. This median ranking is surprising given the old architecture, but it likely reflects the inclusion of many even older and weaker mobile parts in the dataset.

Without rival scores or deltaPct values, the comparative analysis must be qualitative. Against a modern entry-level mobile GPU, the FX 1800M would trail significantly in every metric — FP32 compute, memory bandwidth, and API support. Against its contemporaries from 2009, it would have been competitive in the low-power segment. The 45 W TDP and MXM form factor were standard for professional laptops of that era. The lack of modern features like tensor cores and ray tracing accelerators puts it at a fundamental disadvantage versus any GPU from the last five years. The 1024 MB VRAM is also a severe limitation; modern professional workloads often require 8 GB or more. The data shows a card that was adequate for its time but is now relegated to legacy support or basic display output duties.
