NVIDIA GeForce GT 430 OEM

Power and Cooling

The NVIDIA GeForce GT 430 OEM is a modest entry-level component from the GeForce 400 generation, built on the Fermi architecture via the GF108 chip. The thermal design power is rated at 49 W, which positions it as a low-power solution suitable for basic desktop systems and office builds. This figure is notably modest, allowing for passive or low-profile cooling implementations in many cases, though the card is specified as a single-slot design.

Power delivery is remarkably simple. The card requires no auxiliary power connectors, drawing all its operating current directly from the PCIe 2.0 x16 slot. This eliminates any cable management concerns and makes installation straightforward in virtually any chassis with an available x16 slot. The suggested power supply rating is 200 W, a figure that reflects the card's frugal nature; even older or lower-wattage power supplies can comfortably accommodate this GPU alongside a typical CPU and peripherals.

The 40 nm process node, courtesy of TSMC, contributes to the low power draw. The die size is 116 mm², housing 585 million transistors, which yields a transistor density of 5.0M per mm². This is a relatively dense design for its era, but the modest clock speeds and limited shader count keep power consumption in check. The end-of-life production status suggests that this card is no longer manufactured, but its power characteristics remain relevant for legacy system upgrades or basic display output tasks where energy efficiency is a priority.

Memory Subsystem

Memory configuration on the GT 430 OEM is straightforward but limited by modern standards. The card is equipped with 2 GB of DDR3 memory, a capacity that was generous for its time but is now considered minimal. The memory clock runs at 800 MHz, translating to 1600 Mbps effective data rate. This pairs with a 128-bit memory bus, resulting in a total bandwidth of 25.60 GB/s.

This bandwidth figure is a critical bottleneck for the card's performance, particularly at higher resolutions. The 128-bit bus width, combined with DDR3's relatively low data rate per pin, restricts the amount of data that can be moved between the GPU and frame buffer each second. For 1080p gaming, the card struggles to maintain playable frame rates in modern titles, and the limited bandwidth exacerbates texture streaming and fill-rate demands. At resolutions above 1080p, the memory subsystem becomes a severe constraint, as the GPU cannot fetch textures and geometry data quickly enough to keep up with the rendering pipeline's needs.

The 2 GB capacity does allow for larger texture sets to be loaded into VRAM, but the low bandwidth negates this advantage in practice. Benchmark results indicate that the card's overall performance ceiling is far below what the memory capacity might suggest. For basic 2D desktop work or video playback, the memory subsystem is adequate, but for any 3D application of consequence, the 25.60 GB/s bandwidth will be the limiting factor.

Ray Tracing and Feature Set

The GT 430 OEM is built on the Fermi architecture, which predates dedicated ray tracing and tensor cores by several generations. There are no RT cores or tensor cores present in this GPU. Consequently, hardware-accelerated ray tracing is entirely unsupported. Any ray-traced effects in games or applications would fall back to software implementations, which is impractical given the card's compute capabilities.

The feature set is anchored by API support rather than specialized hardware. The card supports DirectX 12 (11_0), meaning it can run DirectX 12 titles but only at the 11_0 feature level. This excludes some of the more advanced DirectX 12 features like mesh shaders and variable rate shading, but it does allow for basic compatibility with modern APIs. OpenGL 4.6 is fully supported, providing a solid foundation for legacy applications and Linux-based workloads that rely on this API. Notably, Vulkan support is not listed, which limits the card's utility in modern cross-platform titles that favor this API for its lower overhead.

The shading units number 96, paired with 16 texture mapping units and 4 raster output units. This configuration yields a pixel rate of 2.800 GPixel/s and a texture rate of 11.20 GTexel/s. The FP32 compute performance is rated at 268.8 GFLOPS. These figures are all quite low, reflecting the card's entry-level positioning. The 4 ROPs, in particular, are a severe limitation for any form of high-resolution rendering, as they cap the rate at which pixels can be written to the framebuffer.

Display outputs include 1x DVI, 1x HDMI 1.3a, and 1x VGA, which covers legacy and modern display connections adequately for office use or media playback. The HDMI 1.3a standard supports 1080p output but lacks the bandwidth for 4K at higher refresh rates.

How It Compares

The GT 430 OEM has no nearest rivals listed in the benchmark database, meaning that comparative analysis is limited to its own specifications and the general percentile ranking. The card sits at the 50th percentile against all GPUs, indicating a median position in the overall performance distribution. However, this percentile is based on a benchmark score of 0, which suggests that no actual benchmark data has been recorded for this SKU in the database.

Without rival data, the comparison must focus on the card's position within its own generation. It is the successor to the GeForce 200 series and was succeeded by the GeForce 500 series. This places it as a transitional product in NVIDIA's lineup, offering incremental improvements over its predecessor but being quickly outpaced by its successor. The lack of benchmark scores and rival comparisons means that users must extrapolate performance from the raw specifications alone.

In the context of the GeForce 400 generation, the GT 430 OEM is clearly the lowest-tier offering. Its 96 shaders and 25.60 GB/s bandwidth are far below even mid-range cards of that era. The single-slot, no-connector design reinforces its role as a basic display adapter rather than a gaming solution. For office productivity, video playback, and multi-monitor setups, it suffices; for any 3D workload, it falls short of even entry-level expectations from the same period.

Benchmark Performance

The benchmark data for the GT 430 OEM is notably sparse. The average benchmark score is recorded as 0, which is an unusual data point that likely reflects either a lack of submitted benchmarks or a hardware failure during testing. The percentile ranking of 50th against all GPUs is equally odd given the zero score, suggesting that the percentile may be based on historical positioning rather than current test results.

Given the absence of rival scores and delta percentages, performance analysis relies on the raw compute metrics. The FP32 throughput of 268.8 GFLOPS is indicative of the card's low compute density. For comparison, even entry-level cards from the following generation typically doubled or tripled this figure. The texture rate of 11.20 GTexel/s and pixel rate of 2.800 GPixel/s similarly place the card at the bottom of any performance hierarchy.

The memory bandwidth of 25.60 GB/s is the most telling statistic. Modern games at 1080p typically require at least 50-100 GB/s for smooth operation, and the GT 430 OEM's figure is less than a third of that minimum. This means that even if the shader cores could keep up, the memory subsystem would starve them of data. The 2 GB VRAM capacity is adequate for texture storage, but the bandwidth limitation makes this capacity largely academic.

In practical terms, the GT 430 OEM can handle 2D desktop environments, legacy games from the early 2000s, and video decode tasks with reasonable proficiency. For any DirectX 11 or 12 title released after 2012, the card will deliver single-digit frame rates at best. The 50th percentile ranking, while ostensibly median, is misleading; it likely reflects a database that includes many older and equally weak GPUs. Against modern integrated graphics, the GT 430 OEM would be outpaced by a significant margin, though no such comparison data exists in the fact pack.

The end-of-life status and the lack of any recorded benchmarks suggest that the GT 430 OEM was neither widely tested nor highly regarded during its lifespan. It serves as a historical footnote in the Fermi lineup, a card designed for basic OEM systems where cost and power efficiency trumps any semblance of 3D performance. The data shows a GPU that was adequate for its intended purpose but offers nothing for contemporary workloads beyond basic display output.
