About NVIDIA GeForce 9400 GT Rev. 2
The NVIDIA GeForce 9400 GT Rev. 2 is an entry-level graphics card from the GeForce 9 generation, built on the 55 nm Tesla architecture with the G96C chip. It targets basic desktop use and legacy gaming rather than modern high-end workloads.
Benchmark Performance
The 9400 GT Rev. 2 presents a challenging benchmark profile: its average benchmark score is recorded as 0, with an empty benchmarks array in the data. This indicates that no standardized performance metrics are available for this card, placing it in a unique position where quantitative comparisons against other GPUs cannot be drawn from direct scores. The percentile rank of 50 against all GPUs is nominal, reflecting the lack of empirical data rather than a measured performance level.
What the hardware specifications reveal is a compute capacity of 44.80 GFLOPS for FP32 operations. This figure, combined with a pixel rate of 2.200 GPixel/s and a texture rate of 4.400 GTexel/s, paints a picture of a card designed for outputting to displays and handling very light 2D workloads. The 16 shading units and 8 texture mapping units are the minimum necessary to drive a desktop environment. Benchmark results from the era would typically show this card struggling to maintain playable frame rates even at 720p in contemporary titles; the data here, however, offers no direct scores to cite. The effective memory clock of 800 Mbps is low, even for 2008, and directly throttles the fill rates.
The absence of nearestRivals data further complicates analysis. Without deltaPct values or rival names, the 9400 GT Rev. 2 cannot be positioned against the GeForce 8 series it succeeded or the GeForce 200 series that followed it. The performance class is clear from the raw numbers — this is a card for basic video playback and 2D applications — but the specific percentage gaps remain undocumented in this dataset.
Ray Tracing and Feature Set
The 9400 GT Rev. 2 does not feature dedicated ray tracing cores or tensor cores, as those hardware units were not part of the Tesla architecture. The card supports DirectX 11.1, but only at the feature level 10_0, which means it cannot execute the DirectX 11 shader models fully. OpenGL support is listed at version 3.3. There is no Vulkan support recorded.
For API compatibility, this means the card will run older DirectX 9 and DirectX 10 titles, but modern games requiring DirectX 11 features or Vulkan will either fail to launch or run with severe graphical artifacts. The lack of tensor cores also precludes any machine learning acceleration features. The display outputs are limited to 1x DVI, 1x VGA, and 1x S-Video, which restricts modern monitor connectivity without adapters and offers no support for HDMI or DisplayPort natively.
How It Compares
The nearestRivals array is empty, so direct comparison data is unavailable. However, the architectural context from the generation field indicates the predecessor is GeForce 8 and the successor is GeForce 200. Based on the specification sheet, the 9400 GT Rev. 2 would sit at the bottom of the performance stack relative to its predecessor's mid-range offerings, and it would be substantially outclassed by its successor's entry-level parts. The 16 shading units and 4 ROPs are indicative of a cut-down chip, and the 12.80 GB/s memory bandwidth is a bottleneck that no driver optimization could overcome. Without specific benchmark scores or percentile deltas, the analysis must rest on the hardware tiers: this card is the lowest viable option in its generation, suitable only for systems where gaming is not a requirement.
Who Should Consider It
Given the benchmark score of 0 and the hardware specifications, this card is appropriate for a narrow set of use cases. For a home or office PC used for web browsing, document editing, and 1080p video playback, the 9400 GT Rev. 2 provides the necessary display output and 2D acceleration. It is not suitable for gaming at any resolution above 800x600 with reduced detail settings; the 44.80 GFLOPS FP32 throughput and 2.200 GPixel/s pixel rate are insufficient for any 3D workload produced after 2006. At 720p, even older titles will struggle, and at 1080p, the card is effectively unusable for gaming. The 512 MB memory capacity is a further limitation, as many games from the late 2000s already required 1 GB for medium textures. Users with modern operating systems will find the OpenGL 3.3 and DirectX 11.1 (feature level 10_0) support adequate for desktop composition but inadequate for hardware-accelerated web rendering features like WebGL 2.0, which requires OpenGL ES 3.0. The card is best considered as a temporary video output solution or for a retro PC build targeting pre-2005 games.
Memory Subsystem
The memory configuration consists of 512 MB of GDDR3 memory on a 128-bit bus, yielding a bandwidth of 12.80 GB/s. The memory clock is 400 MHz, operating at 800 Mbps effective. This bandwidth is a critical constraint: modern integrated graphics from the same era often had similar or higher bandwidth, and the 12.80 GB/s figure severely limits texture streaming and frame buffer operations at higher resolutions. For 1080p, the 128-bit bus is insufficient to feed even the modest 4.400 GTexel/s texture rate, meaning the card will stall on memory access in any texture-heavy scene. The 512 MB capacity is also a hard ceiling; many games from 2008 onward recommend 1 GB or more, and exceeding this limit forces the card to use system memory over the PCIe 2.0 x16 bus, which is dramatically slower. At 720p and below, the memory subsystem is adequate for basic tasks, but there is no headroom for high-resolution textures or anti-aliasing. The effective memory clock of 800 Mbps is half the speed of higher-tier cards from the same generation, confirming the 9400 GT Rev. 2's position as a low-end part.
Power and Cooling
The 9400 GT Rev. 2 has a thermal design power of 50 W, which is modest by any standard. The card requires no power connectors, drawing all its power from the PCIe 2.0 x16 slot. The suggested power supply is 250 W, which is a low bar that most systems from the era could meet with ease. The card is a single-slot design with a length of 168 mm (6.6 inches), making it compatible with almost any chassis. The cooling solution is not specified in the data, but the 50 W TDP means a simple passive or low-profile active cooler suffices; the card does not generate significant heat. For system builders, this card is nearly trivial to install: no auxiliary power cables, no large cooler clearance issues, and no PSU upgrade needed for most machines. The lack of power connectors also means that the card cannot be overclocked to any meaningful degree without risking instability, as the slot's 75 W power limit is the only source of energy. The 50 W TDP is well within that limit, leaving a small margin for a minor overclock, but the low memory bandwidth and shading unit count make such an attempt futile for performance gains. This is a card that prioritizes simplicity and low power consumption over any performance ambitions.
