About NVIDIA GeForce 8400 GS PCI Rev. 2
The NVIDIA GeForce 8400 GS PCI Rev. 2 is an end-of-life, single-slot PCI graphics card from the GeForce 8 (8400) generation. It is built on NVIDIA's Tesla 2.0 architecture using the GT218S chip, manufactured by TSMC on a 40 nm process. The die contains 260 million transistors and measures 57 mm², for a listed transistor density of 4.6M / mm². The card was released on 2007-04-16, with GeForce 7 PCIe as its predecessor and GeForce 9 as its successor. It carries 512 MB of DDR3 memory, a 64-bit memory bus, and no auxiliary power connectors.
Benchmark Performance
The database entry for this card contains an empty benchmarks array and an average benchmark score of 0. The nearestRivals list is also empty, so there are no rival names, scores, or deltaPct values from which to calculate exact percentage differences. The only relative placement supplied is percentileVsAllGpus: 50, which puts the card at the midpoint of the database GPU distribution. Because no benchmark samples are stored, this percentile cannot be tied to any measured result in the data.
What the entry does provide is a set of absolute throughput figures. FP32 performance is 39.36 GFLOPS. Pixel fill is 2.080 GPixel/s, and texture fill is 4.160 GTexel/s. These figures correspond to a fixed-function pipeline of 16 shading units, 8 texture mapping units, and 4 ROPs. The small unit counts set a low ceiling for shading, texture fetch, and raster work. No base, boost, or game clocks are listed; the only clock value in the entry is the memory clock. With no core clock recorded, the shader and texture rates cannot be decomposed into frequency-per-unit terms. The raw rates stand on their own as the card's specified capabilities.
The empty benchmark table means there is no workload-level score to compare against other GPUs. The 0 average score is not a performance result but the stored aggregate over an empty sample set. In this state, the 50th percentile is the sole comparative marker. It indicates that, within the database population of all GPUs, this model is placed exactly in the middle, but the benchmark data necessary to verify that rank is absent. The architecture is identified as Tesla 2.0, and the GT218S chip's structural profile of 260 million transistors, 57 mm² die area, and 4.6M / mm² density is consistent with a small, low-complexity part.
Memory Subsystem
The memory subsystem is specified as 512 MB of DDR3 on a 64-bit bus. The memory clock is 500 MHz, with an effective data rate of 1000 Mbps. The combination of the effective data rate and the bus width produces the listed bandwidth of 8.000 GB/s. This is a narrow memory path. It provides a small data pipe for moving textures, shader inputs, and frame buffer contents.
For high resolutions, capacity and bandwidth both matter. The 512 MB frame buffer holds the color buffer, depth buffer, and textures; large render targets and high-resolution textures will pressure that capacity. The 64-bit bus and 8.000 GB/s bandwidth limit how quickly pixel and texture data can be transferred between the GPU and memory. The pixel rate of 2.080 GPixel/s means the card cannot generate extremely high pixel throughput in the first place, so the memory subsystem and rendering pipeline are matched at the low end.
The data does not list any memory overclocking or voltage characteristics. The effective data rate and bandwidth are the only memory performance numbers in the pack. For a card of this class, the combination of 512 MB, 64 bits, and 8.000 GB/s defines the boundary of what can be pushed to the display. Higher resolutions will hit the frame buffer capacity before the compute or fill units become the main limitation, and the 8.000 GB/s ceiling will constrain any workload that is memory-bandwidth bound. No FP16 throughput is listed in the entry, so the memory subsystem cannot be paired with any half-precision compute figure; the FP32 figure of 39.36 GFLOPS is the only compute throughput value provided.
Ray Tracing and Feature Set
The entry lists no RT cores and no tensor cores. Consequently, the card has no dedicated ray tracing acceleration hardware and no tensor-based compute blocks. Ray tracing workloads are not covered by any feature in the data. The architecture is identified as Tesla 2.0, and the chip is GT218S, but the feature set is otherwise defined by its API support, unit counts, and display outputs.
The supported API list includes DirectX 11.1 with feature level 10_1, and OpenGL 3.3. No Vulkan version is listed. This means the card's software interface is limited to the DirectX and OpenGL versions in the entry. The feature level 10_1 qualification is part of the DirectX 11.1 entry, so the card's compatibility with DirectX features is specified as 10_1 rather than the full DirectX 11 feature set.
For display connectivity, the card provides 1x DVI, 1x HDMI, and 1x VGA outputs. These three connector types cover both digital and analog display interfaces. The GPU's fixed-function units consist of 16 shading units, 8 texture mapping units, and 4 ROPs. No additional compute-specific hardware is listed. The absence of RT and tensor cores, combined with the modest unit counts, places the card in the conventional rasterization and desktop display segment. The feature set is uncomplicated: a small fixed-function GPU with basic API and connector support.
Power and Cooling
The power envelope is defined by a TDP of 40 W and a suggested PSU of 200 W. The card is single-slot and has no power connectors. With no auxiliary power input, all power is drawn through the PCI bus interface. The bus interface is explicitly listed as PCI. Installers need a PCI slot rather than a separate power cable.
The 40 W TDP is modest, and the absence of power connectors aligns with a low-power card. The suggested PSU of 200 W is likewise a low-capacity recommendation. The cooling solution is not described by name in the data; the only physical constraints given are the single-slot width and the TDP. No card dimensions are listed, so length, height, and width clearance data is unavailable.
Because the card is end-of-life, the 40 W TDP and 200 W PSU figures remain the relevant electrical specifications for any installation. The single-slot form factor means it occupies one expansion slot. The lack of external power connectors means no additional GPU power cable management is required. The PCI bus interface is the final compatibility check, and the absence of auxiliary power connectors keeps the electrical installation simple.
How It Compares
The nearestRivals array is empty. There are no rival names, no rival scores, and no deltaPct values in the entry. As a result, this section cannot report a percentage lead or deficit against any specific competitor. The only comparative metric is percentileVsAllGpus: 50, which places the card in the middle of the database's GPU distribution.
The predecessor is GeForce 7 PCIe, and the successor is GeForce 9. No benchmark scores are listed for either product, so their relationship to the 8400 GS PCI Rev. 2 is chronological rather than performance-based. The release date is 2007-04-16, and production status is end-of-life. The card therefore sits at the end of its own product lifecycle. The series and codename fields are not populated, leaving the GeForce 8 (8400) generation and Tesla 2.0 architecture as the only classification labels.
In the absence of nearestRivals, the card's identity is defined by its specifications: 512 MB DDR3 memory, a 64-bit bus, 8.000 GB/s bandwidth, 16 shading units, 8 TMUs, 4 ROPs, 39.36 GFLOPS FP32 throughput, a 40 W TDP, and a single-slot PCI form factor. The average benchmark score is 0, and the benchmarks array is empty, so no sample-based ranking exists beyond the 50th percentile. Any broader comparison against other GPUs would require the nearestRivals records, which are not present in this data set.
