Shader units and compute resources
The NVIDIA GeForce GT 430 PCI GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.
GT 430 PCI Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the GeForce GT 430 PCI's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The GeForce GT 430 PCI by NVIDIA dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
NVIDIA's GeForce GT 430 PCI Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The GeForce GT 430 PCI's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.

About NVIDIA GeForce GT 430 PCI
The NVIDIA GeForce GT 430 PCI is a Fermi-generation card built around the GF108 chip on TSMC's 40 nm process. It packs 585 million transistors on a 116 mm² die, giving a transistor density of 5.0M / mm². The card ships with 512 MB of DDR3 memory on a 64-bit bus, provides 96 shading units, 16 TMUs, and 4 ROPs, and is rated for a 49 W TDP. Released on 2010-10-10, it is listed as end-of-life and uses a PCI bus interface. The database entry contains no benchmark entries, no nearest rivals, and no launch MSRP, so the analysis here is based on the listed specifications.
Benchmark Performance
The database entry for the GeForce GT 430 PCI does not include any individual benchmark scores. The average benchmark score field is recorded as 0, and the percentile field places the card at 50 among all GPUs in the database. However, with no benchmark workloads stored, score-based deltas cannot be computed. The nearestRivals list is empty, meaning there are no rival names, scores, or deltaPct values to cite. Consequently, there are no exact percentage differences to report against competing cards.
The only quantitative performance indicators are the specification-derived rates. FP32 compute is 268.8 GFLOPS, texture fill is 11.20 GTexel/s, and pixel fill is 2.800 GPixel/s. These three figures define the card’s raw throughput. The 268.8 GFLOPS figure represents the peak floating-point work the card can perform per second, while 11.20 GTexel/s indicates how quickly it can address texture data and 2.800 GPixel/s shows the rate at which pixels can be written to the framebuffer. With only 4 ROPs available, the pixel rate is inherently limited. The 50th percentile rank should be treated cautiously: since the average benchmark score is 0 and there are no benchmark entries sampled, the percentile is not supported by actual measurements in this record. The practical conclusion is that comparative benchmark analysis is unavailable from this data.
Ray Tracing and Feature Set
No RT cores or tensor cores are listed in the specification. This means the card has no dedicated hardware blocks for ray tracing or tensor-based workloads in the database record. The feature set is instead defined by the Fermi architecture, the GF108 chip, and the API support. The listed APIs are DirectX 12 (11_0), OpenGL 4.6, and no Vulkan entry. The DirectX 12 (11_0) listing points to a feature level rather than a full modern DirectX 12 implementation, as the parenthetical feature level is 11_0. OpenGL 4.6 support is present, but Vulkan support is absent from the data, so any Vulkan-based application cannot be validated against this product’s specification.
The card’s display outputs are 1x DVI, 1x HDMI 1.3a, and 1x VGA. That is a legacy-friendly set of outputs. The HDMI 1.3a standard and VGA connection reflect the card’s release period. The architecture is Fermi, built on a 40 nm process at TSMC. The die contains 585 million transistors on 116 mm², with a transistor density of 5.0M / mm². These figures describe a small, early-2010s chip. The absence of tensor and RT cores means any ray tracing or AI-assisted rendering features are not supported by dedicated hardware in this card. The feature set is therefore centered on conventional rasterization and display output.
Memory Subsystem
The memory subsystem consists of 512 MB of DDR3 on a 64-bit bus. The memory clock is 600 MHz, or 1200 Mbps effective, yielding a bandwidth of 9.600 GB/s. For high-resolution workloads, this configuration is restrictive. 512 MB of capacity is small for large framebuffers, and 9.600 GB/s is a narrow data path for moving large amounts of image data. The 64-bit bus means all memory traffic must fit through a relatively small interface. The card also has 4 ROPs and a pixel rate of 2.800 GPixel/s, so the pixel output rate is modest as well.
In practice, the memory bandwidth and capacity constrain the card to low-resolution or lightweight rendering tasks. A 512 MB framebuffer cannot hold the texture and depth data typically associated with high-resolution gaming. The 9.600 GB/s bandwidth is enough for simple desktop use and older workloads, but it will saturate quickly when rendering detailed scenes. The memory clock of 600 MHz, with 1200 Mbps effective, is the only clock speed listed for the card; there is no base or boost clock in the data. The combination of DDR3, a 64-bit bus, and 512 MB capacity points to a deliberately low-power, entry-level memory design.
Who Should Consider It
Given the absence of benchmark scores, the suitability of this card has to be inferred from its specification. The 268.8 GFLOPS FP32 rate, 11.20 GTexel/s texture rate, 2.800 GPixel/s pixel rate, and 512 MB memory bus combine to position the card as a basic display adapter for a legacy PCI system. The 49 W TDP and lack of auxiliary power connectors reinforce that this is not a high-throughput board. It will be of interest to users who need a single-slot, low-power video output for a system that lacks a more modern bus interface. The 145 mm / 5.7 inch length helps fit small cases.
For high-resolution, high-detail workloads, the data suggests the card is not equipped. The memory bandwidth is 9.600 GB/s and the framebuffer is 512 MB. The 64-bit memory bus, 96 shading units, 16 TMUs, and 4 ROPs provide limited parallel throughput. The card is more plausible as a solution for desktop output, simple 2D acceleration, or systems where the PCI bus interface is the only available expansion option. Because the production status is end-of-life, this is a legacy product rather than a current-generation component. The data lists GeForce 200 as its predecessor and GeForce 500 as its successor, placing it in the middle of that product transition.
Power and Cooling
The card is rated for a 49 W TDP, and the database lists a suggested PSU of 200 W. It requires no auxiliary power connectors, so a standard slot-only power feed is sufficient. The card occupies a single slot and is 145 mm / 5.7 inches long. With a 40 nm Fermi chip and no separate power inputs, the board has a modest thermal envelope. The single-slot layout is consistent with a low-heat design. The 49 W TDP means cooling is not a major concern in most systems. The lack of power connectors simplifies installation because no extra cable routing is required. The 200 W suggested PSU figure is the power supply guideline provided in the database, and it applies to a system using this card as specified. The end-of-life status indicates that the card is no longer in production, but the power and cooling requirements remain clearly defined by the listed specifications.
