About NVIDIA GeForce 8400 GS Rev. 2
The GeForce 8400 GS Rev. 2 is an end-of-life entry-level graphics card from NVIDIA’s Tesla architecture, built on a 65 nm process at UMC with 210 million transistors on an 86 mm² die. It targets basic desktop use and legacy systems, offering a minimal feature set that aligns with its 50th percentile standing among all GPUs in the database. The card carries no benchmark scores of its own, so its position is defined entirely by architectural capabilities and interface support rather than measured performance.
Memory Subsystem
The GeForce 8400 GS Rev. 2 comes equipped with 512 MB of DDR2 memory, paired with a 64-bit bus width. This configuration yields a memory bandwidth of 6.400 GB/s, a figure that reflects the card’s entry-level positioning. The memory clock runs at 400 MHz, translating to 800 Mbps effective data rate — a modest speed that aligns with the DDR2 standard of its era.
For high-resolution workloads, the data indicates clear limitations. The 64-bit bus is half the width of mainstream cards from its generation, and the 6.400 GB/s bandwidth is sufficient only for low-resolution textures and simple frame buffers. At resolutions above 1080p, the memory subsystem would struggle to feed the shading units efficiently, causing frame rates to drop sharply as texture data exceeds the available bandwidth. The 512 MB capacity also caps the size of texture sets and render targets, making modern high-resolution assets impractical.
Pixel and texture rates are closely matched at 2.268 GPixel/s and 2.268 GTexel/s, respectively, suggesting a balanced but constrained pipeline. The 4 ROPs and 4 TMUs further reinforce the card’s role as a 2D desktop accelerator rather than a gaming performer. In practice, the memory subsystem is adequate for basic OS rendering and legacy applications, but benchmark results would show severe bottlenecks in any scenario requiring sustained memory throughput.
Ray Tracing and Feature Set
This GPU does not include dedicated ray tracing cores or tensor cores. Instead, it relies on the Tesla architecture’s basic compute capabilities, with 8 shading units delivering 22.40 GFLOPS of FP32 performance. The absence of RT and tensor hardware means no hardware-accelerated ray tracing, no DLSS-style upscaling, and no AI-based features — the card is strictly a rasterization device.
API support is limited to DirectX 11.1 (feature level 10_0) and OpenGL 3.3, with no Vulkan support listed. The DirectX 11.1 designation with a 10_0 feature level is particularly telling: it means the card can run some DirectX 11 titles but only through compatibility paths that reduce them to DirectX 10-class features. This places it below the feature set of contemporary entry-level GPUs from its release period, which typically supported full DirectX 10 or 10.1. OpenGL 3.3 allows for basic modern OpenGL applications, but again, without hardware acceleration for advanced features, performance would lag.
The display outputs include 1x DVI, 1x VGA, and 1x S-Video, covering legacy monitors and TV connections. The card uses a PCIe 2.0 x16 interface, which is backward compatible but offers no bandwidth advantage for its small memory footprint. Power requirements are minimal — the card draws 25 W TDP and requires no power connectors, with a suggested PSU of 200 W. This makes it a drop-in upgrade for older office PCs, but the feature set offers no headroom for modern gaming or compute tasks.
Benchmark Performance
The database lists no benchmark scores for the GeForce 8400 GS Rev. 2, and the nearestRivals array is empty. This absence of data means no direct percentage deltas can be calculated against competing products. However, the architectural figures provide a basis for qualitative comparison.
With 22.40 GFLOPS of FP32 performance and 2.268 GPixel/s pixel fill rate, the card sits in the lowest tier of GPUs from its generation. For context, the 8 shading units and 4 TMUs are half the counts found on mid-range cards of the same era, and the 64-bit memory bus is a quarter of the width used by high-end models. The 50th percentile ranking among all GPUs in the database is likely a reflection of its ubiquity in budget systems rather than its compute prowess, as many integrated graphics solutions of that time offered similar or better throughput.
The lack of benchmark scores also means the card’s real-world performance cannot be verified against rivals. What the data does show is a hard ceiling: the memory bandwidth of 6.400 GB/s and pixel rate of 2.268 GPixel/s would limit even simple 3D scenes to low detail settings at 1024x768 or 1280x1024 resolutions. For anything beyond 2D desktop work or video playback, the card would fall behind even entry-level integrated graphics from its release period, which typically had access to system memory with higher bandwidth.
How It Compares
Since no nearest rivals are provided, the comparison must rely on the card’s own specifications against the broader market context implied by its generation and architecture. The GeForce 8400 GS Rev. 2 is a successor to the GeForce 7 PCIe series, and its predecessor’s feature set would include similar limitations — the 8400 GS Rev. 2 adds a newer process node and DirectX 11.1 API support, but the core hardware specs remain entry-level. The successor, GeForce 9, would offer higher shader counts and improved memory bandwidth, but no specific numbers are available in the fact pack for that comparison.
Against potential rivals from AMD or older NVIDIA parts, the 8400 GS Rev. 2’s 64-bit memory bus and 4 ROPs would place it at the bottom of any performance chart. The 25 W TDP is a positive for low-power systems, but that advantage does not translate into compute capability. The card’s single-slot design and lack of power connectors make it easy to install in legacy systems, but the 170 mm length (6.7 inches) is standard for its class.
In the absence of direct benchmark comparisons, the most accurate statement is that the GeForce 8400 GS Rev. 2 occupies the absolute entry tier of discrete GPUs, with specifications that prioritize low cost and low power over any form of performance. Its 50th percentile rank likely reflects its historical sales volume in basic office PCs rather than any gaming or workstation relevance.
