NVIDIANVIDIA GeForce GT 230 Specifications
GeForce GT 230 GPU Core
Shader units and compute resources
The NVIDIA GeForce GT 230 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 230 Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the GeForce GT 230'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 230 by NVIDIA dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
NVIDIA's GeForce GT 230 Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The GeForce GT 230'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.
GeForce GT 230 by NVIDIA Cache
On-chip cache hierarchy
On-chip cache provides ultra-fast data access for the GT 230, reducing the need to fetch data from slower VRAM. L1 and L2 caches store frequently accessed data close to the compute units. AMD's Infinity Cache (L3) dramatically increases effective bandwidth, improving GPU benchmark performance without requiring wider memory buses. Larger cache sizes help maintain high frame rates in memory-bound scenarios and reduce power consumption by minimizing VRAM accesses.
GT 230 Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the NVIDIA GeForce GT 230 against other graphics cards. FP32 (single-precision) performance, measured in TFLOPS, indicates compute capability for gaming and general GPU workloads. FP64 (double-precision) matters for scientific computing. Pixel and texture fill rates determine how quickly the GPU can render complex scenes. While real-world GPU benchmark results depend on many factors, these specifications help predict relative performance levels.

Manufacturing and design details
The NVIDIA GeForce GT 230 is built on NVIDIA's Tesla architecture, which defines how the GPU processes graphics and compute workloads. The manufacturing process node affects power efficiency, thermal characteristics, and maximum clock speeds. Smaller process nodes pack more transistors into the same die area, enabling higher performance per watt. Understanding the architecture helps predict how the GT 230 will perform in GPU benchmarks compared to previous generations.
NVIDIA's GeForce GT 230 Power & Thermal
TDP and power requirements
Power specifications for the NVIDIA GeForce GT 230 determine PSU requirements and thermal management needs. TDP (Thermal Design Power) indicates the heat output under typical loads, guiding cooler selection. Power connector requirements ensure adequate power delivery for stable operation during demanding GPU benchmarks. The suggested PSU wattage accounts for the entire system, not just the graphics card. Efficient power delivery enables the GeForce GT 230 to maintain boost clocks without throttling.

About NVIDIA GeForce GT 230
The NVIDIA GeForce GT 230 is an end-of-life GPU from the GeForce 200 generation. Released in 2009, it uses the G94B chip built by TSMC on a 55 nm process, containing 505 million transistors on a 196 mm² die. The memory subsystem is 512 MB GDDR3 on a 256-bit bus, with a bandwidth of 57.60 GB/s and a memory clock of 900 MHz / 1800 Mbps effective. No base, boost, or game clocks are listed. The GPU includes 48 shading units, 24 texture mapping units, and 16 ROPs, with theoretical rates of 156.0 GFLOPS FP32, 10.40 GPixel/s, and 15.60 GTexel/s. Its TDP is 75 W, the suggested PSU is 250 W, and no power connectors are required. The database percentile versus all GPUs is 50, while the average benchmark score is 0.
Who Should Consider It
The GT 230 is not a card for users who need a display connection: the database records “No outputs” in the display outputs field. Because no display connectors are present, the card would require a separate GPU or integrated graphics to drive a monitor. That makes it a candidate for auxiliary compute tasks or for use in a secondary system rather than a primary graphics solution. The memory configuration reinforces that role. 512 MB of GDDR3 is small for workloads with large textures or high-resolution buffers, and the 57.60 GB/s bandwidth limits how quickly data can move between memory and the 48 shading units. With 156.0 GFLOPS FP32, the card is best suited to simple rendering, basic post-processing, or other light compute workloads. The 10.40 GPixel/s pixel rate and 15.60 GTexel/s texture rate are low ceilings for fill-rate-sensitive work. Users who already have a display source and need a low-power, single-slot compute companion fit the profile. The 75 W TDP and absence of power connectors allow installation in systems with the listed 250 W PSU, as long as a PCIe 2.0 x16 slot is available. The production status is end-of-life, so the audience is likely limited to older systems or niche roles. The 50th percentile position relative to all GPUs suggests a median part, but with an empty benchmark array the measured performance behind that percentile is unknown.
Ray Tracing and Feature Set
Hardware ray tracing is not present: the RT cores field is null. Tensor cores are likewise absent, so tensor-accelerated workloads have no dedicated hardware on this GPU. The feature set is defined by the Tesla architecture and the G94B chip. The API support table lists DirectX 11.1 with feature level 10_0 and OpenGL 3.3; Vulkan is not listed. The feature level 10_0 is a key detail: it means the API version is DirectX 11.1 but the hardware feature set corresponds to DirectX 10-class capabilities. That distinction matters because some DirectX 11 software expects feature levels above 10_0. OpenGL 3.3 support gives access to a subset of OpenGL applications, but newer OpenGL revisions are not listed. The FP16 field is null, so half-precision throughput is not specified. No RT cores and no tensor cores mean no hardware ray tracing and no tensor operations; both are outside the GT 230’s feature set. The lack of Vulkan support further limits modern cross-platform engine use.
How It Compares
The nearestRivals list is empty. There are no rival names, no scores, and no deltaPct values in the database entry for the GT 230. Consequently, this section cannot describe head-to-head performance against specific competitors. The only comparison data are the non-rival fields: the predecessor is GeForce 9 and the successor is GeForce 400, placing the GT 230 between those generations. Within the GeForce 200 generation, it uses the Tesla architecture on the G94B chip. The database percentile of 50 versus all GPUs gives a coarse relative placement: it is at the midpoint of the database’s all-GPU distribution. That is not a substitute for nearestRivals comparisons. No deltaPct exists to state a percentage ahead of or behind any named product. Any such statement would require nearestRivals data, so none can be made here. The empty benchmark array reinforces the absence of measurable comparison points. This card’s position is therefore best described by generation lineage and percentile, not by rival performance.

Benchmark Performance
The benchmark performance record for the GT 230 contains almost nothing to analyze. The benchmarks array is empty, and the average benchmark score field is 0. There are no recorded application scores, so no measured performance can be quoted. In addition, the nearestRivals array is empty, which means there are no deltaPct values to calculate exact percentage differences from competing products. The only quantitative performance indicators are theoretical hardware limits: 156.0 GFLOPS FP32, 10.40 GPixel/s, and 15.60 GTexel/s. These are peak rates, not benchmark outcomes. The 57.60 GB/s memory bandwidth is a practical ceiling for data movement between the 512 MB buffer and the rest of the GPU. The 256-bit bus width gives the memory subsystem some headroom, but the capacity of 512 MB is the more binding constraint for texture-heavy or high-resolution workloads. The database percentile of 50 places the GT 230 at the midpoint among all GPUs, though the empty benchmark array means this percentile has no underlying recorded runs in the entry. No base, boost, or game clocks are listed, so clock-dependent benchmark comparisons are also impossible. Any claim of being a certain percentage faster or slower than a rival cannot be supported by this record.
Power and Cooling
Power figures are straightforward. The GT 230 has a TDP of 75 W. The listed suggested PSU is 250 W. Power connectors are not required, and the card is single-slot. All power must therefore be drawn through the PCIe 2.0 x16 bus interface, since no auxiliary connector is documented. The chip is manufactured on a 55 nm TSMC process, with 505 million transistors and a die size of 196 mm²; transistor density is 2.6 million per square millimeter. These process figures help explain the modest 75 W power target. A single-slot design is recorded, consistent with a low-power board, though the database does not specify a cooler model. The absence of power connectors simplifies installation: no auxiliary power cables need to be routed. The 250 W suggested PSU provides a planning target for system builders. The card’s power requirements are limited to the 75 W TDP, so the main constraints on integration are the PCIe 2.0 x16 bus interface and the physical slot requirement.
