About NVIDIA GeForce 9400 GT Rev. 3
Benchmark Performance
The NVIDIA GeForce 9400 GT Rev. 3 presents a unique profile in the benchmark database, with its percentile ranking of 50 placing it at the exact midpoint of all recorded GPUs. This is a remarkably neutral position, indicating that while it is not a high-flying performer, it is also not relegated to the absolute bottom tier of graphics hardware. However, the average benchmark score of zero suggests that there is no standardized performance data collected for this specific revision, meaning the percentile ranking may reflect its architectural class rather than direct, measured results.
The raw computational metrics paint a clear picture of its intended role. The card delivers 44.86 GFLOPS of FP32 compute, a figure that categorizes it firmly within the entry-level segment. Its pixel rate of 2.356 GPixel/s and texture rate of 4.712 GTexel/s are derived from its 4 ROPs and 8 TMUs respectively, which are paired with just 16 shading units. These numbers indicate a chip designed for basic 2D acceleration, video playback, and very light 3D workloads, not for competitive gaming or content creation.
When contextualized against its own architecture, the Tesla 2.0 design on a 40 nm process node allows for a transistor density of 4.6 million transistors per square millimeter, packing 260 million transistors into a die size of just 57 mm². The memory subsystem is a significant bottleneck: 128 MB of DDR2 memory on a 64-bit bus yields a bandwidth of only 9.600 GB/s. This is a critical limitation, as even the modest shading unit count would struggle to be fed by such constrained memory throughput. The effective memory clock of 1200 Mbps is standard for DDR2 of that era, but the narrow bus width severely caps performance in any memory-intensive scenario.
In practical terms, the data suggests that the 9400 GT Rev. 3 will exhibit severe frame rate limitations in any modern 3D application. The combination of 16 shaders, 4 ROPs, and 9.6 GB/s of bandwidth is a fraction of what even low-end contemporary GPUs offer. Its performance profile is best understood as a legacy part: adequate for Windows Aero, HD video decode, and perhaps very old DirectX 9 titles at low resolutions, but entirely outclassed by even the most basic modern integrated graphics solutions. The zero benchmark score is telling; no standardized test suite has recorded a meaningful result for this card, reinforcing its status as a relic rather than a functional gaming product.
Power and Cooling
The power characteristics of the GeForce 9400 GT Rev. 3 are among its most defining features. The card carries a TDP of just 50 W, a figure that is exceptionally low by modern standards. This low thermal design power means that the cooling solution is minimal; it is a single-slot card, which is typical for GPUs of this class. The lack of any power connectors on the board is a direct consequence of this low TDP, as the card draws all its power from the PCIe 2.0 x16 slot itself.
For system integration, the suggested PSU requirement is 250 W. This is a very modest recommendation, making the card compatible with almost any desktop power supply from its era and even many modern low-wattage units. However, the data indicates that the card has no supplemental power connectors, which simplifies installation considerably. There is no need to route additional 6-pin or 8-pin cables, and the card will function in any system with a free PCIe x16 slot and a PSU that meets the 250 W threshold.
Physically, the card measures 168 mm in length, equivalent to 6.6 inches. This compact footprint ensures that it will fit in the majority of cases, including small form factor systems. The 40 nm manufacturing process is a key contributor to the low power draw; a smaller process node typically yields better efficiency, and the 260 million transistors here are evidently tuned for minimal power consumption rather than maximum performance. The absence of a fan header or any other power-related feature in the specification further underscores the simplicity of this card's power delivery.
From a thermal management perspective, the 50 W TDP is well within the range that a passive heatsink or a small, low-speed fan can handle. The single-slot design is possible precisely because the heat output is so constrained. In a benchmark context, this means the card will not contribute significantly to system case temperature, and users do not need to worry about additional cooling considerations beyond standard case airflow. The production status is end-of-life, so power draw is the only relevant metric for those considering legacy system builds; it is one of the least demanding GPUs ever produced in terms of system power delivery.
How It Compares
The FACT PACK lists no nearest rivals for the GeForce 9400 GT Rev. 3, and its benchmark array is empty. This absence of comparative data is itself a finding. The card's percentile rank of 50, without any rival scores or deltaPct values, suggests that the database does not have sufficient standardized metrics to place it against other GPUs in a meaningful head-to-head fashion.
Within its own generational context, the card sits at the low end of the GeForce 9 series. Its predecessor is the GeForce 8 line and its successor is the GeForce 200 series, but no specific performance deltas are provided for either. The lack of benchmark scores means that any quantitative comparison would be speculative. The only objective data available are its raw specs, which can be interpreted as follows: the 16 shading units and 4 ROPs place it well below the mid-range of its own generation, and the 128 MB memory capacity is a clear indicator of its entry-level positioning.
The absence of rivals in the database is likely due to the card's end-of-life status and the fact that its performance is so low that it has not been included in modern comparative test suites. The zero average benchmark score reinforces this interpretation. For a hardware analyst, this means the 9400 GT Rev. 3 is a card that exists in a data vacuum; it is defined more by its limitations than by any competitive positioning. The 50th percentile rank is a statistical artifact of the database's GPU population, not a reflection of direct performance parity with any specific model.
If one were to hypothesize based on the available specifications, the card would sit far below any GPU with even twice the shading units and memory bandwidth. The 9.6 GB/s bandwidth and 44.86 GFLOPS compute are figures that were low even at the time of its 2012 release. In a modern context, it is functionally obsolete for 3D rendering. The lack of rival data, therefore, is not a gap in the database but rather a reflection of the card's irrelevance to any comparative performance discussion.

Ray Tracing and Feature Set
The GeForce 9400 GT Rev. 3 does not include any dedicated ray tracing cores or tensor cores. This is consistent with its Tesla 2.0 architecture, which predates the introduction of such specialized hardware. The absence of these units means the card is entirely incapable of hardware-accelerated ray tracing, a feature that would not appear in NVIDIA's consumer GPUs until many years later. Similarly, there are no tensor cores for AI-accelerated workloads, so any machine learning or DLSS-type functionality is completely unsupported.
The API support is a critical aspect of the feature set. The card supports DirectX 11.1, but only at feature level 10_1. This is an important distinction; while the API version is nominally DirectX 11, the feature level 10_1 means that it does not support the full DirectX 11 feature set. Shader Model 4.1 is implied, not 5.0, which limits the card's compatibility with games that require higher feature levels. OpenGL 3.3 support is also present, which is adequate for some older titles and applications, but incompatible with many modern OpenGL 4.x requirements.
The display output configuration consists of one DVI port, one VGA port, and one S-Video connector. This is a legacy output set, lacking any HDMI or DisplayPort connectivity. For modern display connectivity, an adapter would be required for DVI to HDMI, and VGA is largely obsolete. The absence of modern digital outputs further confirms the card's vintage status. The pixel rate of 2.356 GPixel/s and texture rate of 4.712 GTexel/s are the fundamental limits for any rendering task, and these figures are too low for any contemporary graphical workload.
The 16 shading units are arranged in a configuration that yields 44.86 GFLOPS of FP32 compute. This is a theoretical peak that is far below the teraflop range of modern GPUs. The 4 ROPs are responsible for pixel output, and their low count directly impacts fill-rate-limited scenarios. The 8 TMUs handle texture filtering, but with a bandwidth of 9.6 GB/s, the texture units will frequently stall waiting for data. In summary, the feature set is minimal: no RT, no tensor cores, limited API support, and a barebones display output. This card is a product of its time, designed for basic desktop use rather than any advanced graphical processing.
