NVIDIA GeForce 9400

The NVIDIA GeForce 9400 is an integrated graphics processor (IGP) from the GeForce 9 IGP generation, built on the C79 chip using the Tesla architecture. Manufactured on a 65 nm process, it packs 314 million transistors onto a 144 mm² die, yielding a transistor density of 2.2M / mm². Released in 2008, this part holds a 50th percentile rank among all GPUs, yet its average benchmark score is recorded as zero, indicating a lack of standardized test data. As an end-of-life product with a PCI bus interface, it occupies a specific niche in legacy systems, and its system-shared memory configuration defines its operational limits.

Benchmark Performance

The benchmark profile for the GeForce 9400 is notably sparse. The database shows an average benchmark score of zero, which means no modern workload has successfully executed on this hardware. The 50th percentile rank is a default placement rather than a measured performance result, as the zero score cannot support a meaningful comparison. Without any nearestRivals entries, there are no direct deltaPct values to cite, so the analysis must rely on theoretical specifications. The FP32 compute throughput is 35.20 GFLOPS, a figure that reflects the 16 shading units operating at the given clock. The pixel rate of 1.800 GPixel/s and texture rate of 3.600 GTexel/s are derived from the 4 ROPs and 8 TMUs respectively. These numbers indicate a 2:1 texture-to-pixel ratio, which is typical for a low-end integrated design. The 314 million transistor count on a 144 mm² die gives a density of 2.2M / mm², a low figure that confirms the simplicity of the architecture. In practice, this translates to performance suitable only for basic 2D operations and very light 3D rendering. The data suggests that the 9400 would be dramatically outperformed by any discrete GPU from its era, but without rival scores, we cannot quantify the gap. The 50th percentile rank is misleading, as it implies a median standing, but the zero score contradicts that. Benchmark results indicate that this IGP was never intended for demanding workloads. The 35.20 GFLOPS figure is a hard ceiling for compute tasks, and the 1.800 GPixel/s fill rate limits any pixel-heavy operation. The 3.600 GTexel/s texture rate is similarly constrained, making even moderate texture filtering a bottleneck. The data shows a clear performance ceiling that is orders of magnitude below what modern applications require.

Ray Tracing and Feature Set

The GeForce 9400 lacks any dedicated ray tracing cores or tensor cores, with both fields listed as null. This is a direct consequence of its 2008 release and integrated positioning. The API support is limited to DirectX 11.1 with a feature level of 10_0, and OpenGL 3.3. The DirectX 11.1 support is nominal, as the 10_0 feature level restricts the shader model to 4.0, preventing access to many DirectX 11 features. OpenGL 3.3 is also a legacy version, lacking modern extensions. Vulkan is not supported, as the field is null. This means the GPU cannot accelerate hardware ray tracing or any tensor-based operations, such as AI upscaling or denoising. For contemporary applications, the lack of Vulkan support is a significant barrier, as many modern engines rely on it. The feature set is effectively frozen at the state of the art from 2008. The absence of these advanced features makes the 9400 unsuitable for any workload that requires modern graphics APIs or compute acceleration. The 10_0 feature level is particularly restrictive, as it caps the hardware at Direct3D 10-era functionality despite the nominal 11.1 label. Without tensor cores, there is no path for machine learning inference. Without ray tracing cores, there is no hardware acceleration for global illumination or reflections. The data indicates that this part is purely a rasterization engine with no forward-looking capabilities.

Memory Subsystem

The memory subsystem of the GeForce 9400 is entirely system-shared. The size, type, and bus width are all listed as "System Shared," and the bandwidth is "System Dependent." This configuration means the GPU has no dedicated VRAM and instead borrows from the host system's main memory. Consequently, the effective memory performance is directly tied to the system's RAM speed and architecture. The system-dependent bandwidth is a critical limitation, as it introduces latency and contention with the CPU. At high resolutions, the lack of a dedicated memory bus becomes a severe bottleneck. The frame buffer and texture data must traverse the shared system bus, which is typically slower than a dedicated VRAM interface. The 4 ROPs further constrain pixel throughput, limiting the fill rate to 1.800 GPixel/s. This combination of shared memory and low ROP count means that high-resolution rendering will be severely degraded. The data shows that the 9400 is only viable at low resolutions, where the memory bandwidth demands are modest. The system-dependent nature of the bandwidth means that performance can vary widely between different host systems, making it an unpredictable platform for gaming. Because the memory type is also system-shared, there is no dedicated high-speed memory controller for the GPU, meaning the CPU and GPU compete for the same memory channels. This contention further reduces effective bandwidth, especially in multitasking scenarios. The lack of a fixed bus width means that the theoretical peak bandwidth is never achievable, as it depends entirely on the host platform's memory configuration.

Who Should Consider It

Given the absence of benchmark scores and the modest theoretical figures, the GeForce 9400 is only appropriate for basic system operation. The 16 shading units, 8 TMUs, and 4 ROPs, combined with system-shared memory, indicate it can handle 2D desktop environments, video playback, and very light 3D tasks at low resolutions. The 50th percentile rank is not a reliable indicator of gaming capability, as it is based on a zero score. Users with legacy systems from the 2008 era might use this for office productivity or as a display output. The display outputs are limited to 1x DVI, 1x VGA, and 1x S-Video, which restricts connectivity to older monitors. It is an end-of-life product, so no new purchases are warranted. The predecessor is the GeForce 8 IGP, and the 9400 offers incremental improvements, but without a successor listed, it represents the final step in this IGP line. For anyone requiring modern graphics features, this part is not a consideration. The data indicates that it is not viable for modern gaming, even at low settings, due to the lack of dedicated VRAM and the low fill rates. The 1.800 GPixel/s pixel rate and 3.600 GTexel/s texture rate are insufficient for any game released after the mid-2000s. The 35.20 GFLOPS compute capacity is likewise inadequate for physics or post-processing effects. The data does not support any gaming recommendation, and the zero benchmark score reinforces that this part is best left to basic display duties.

Power and Cooling

The thermal design power (TDP) for the GeForce 9400 is 40 W. This is a low figure, reflecting the integrated nature of the chip. As an IGP with a slot width of "IGP," it is not a discrete card but is integrated into the motherboard chipset (C79). Consequently, it does not require any external power connectors; the powerConnectors field is null. The suggested PSU field is also null, indicating that no specific power supply recommendation is necessary. The 40 W TDP is well within the capabilities of standard desktop power supplies from its era. Since it is an IGP, cooling is typically provided by a passive heatsink or the system's case airflow, rather than a dedicated fan. The 65 nm process node contributes to the relatively low power draw. The bus interface is PCI, which is an older standard compared to PCI Express, further reinforcing its legacy status. Overall, the power requirements are minimal, making it suitable for low-power office systems. The data shows that the 40 W TDP is a defining characteristic, allowing for integration into compact or low-cost motherboards without additional cooling infrastructure. The absence of a power connector and suggested PSU simplifies installation, as any standard desktop power supply can handle the load. The 40 W figure is a fixed maximum, and actual power draw will be lower under typical 2D workloads. The IGP slot width means there is no physical card to install, and the PCI interface is a direct connection to the chipset. This design prioritizes simplicity and low power over performance, which is consistent with the 50th percentile rank and zero benchmark score.
