NVIDIA GeForce GT 340 OEM

The NVIDIA GeForce GT 340 OEM is a GeForce 300-generation GPU built around the GT215 chip and Tesla 2.0 architecture. It was listed with a release date of 2010-02-01 and a production status of end-of-life. The card uses a 40 nm process at TSMC, with 727 million transistors on a 144 mm² die. Memory is 1024 MB of GDDR3 on a 128-bit bus, and the database entry records no nearest-rival entries and an average benchmark score of 0. The GT 340 OEM is placed between the GeForce 200 predecessor and GeForce 400 successor in the data.

Memory Subsystem

The memory subsystem is built around 1024 MB of GDDR3 with a 128-bit bus. Memory clocks are listed at 850 MHz, or 1700 Mbps effective. The resulting memory bandwidth is 27.20 GB/s. That bandwidth figure is the rate at which the GPU can move data to and from video memory, and it directly bounds how much texture and geometry data can be supplied per second. For high-resolution workloads, the 1024 MB capacity is the first constraint: larger framebuffers and larger texture sets consume the buffer quickly. The 27.20 GB/s figure is the second constraint, because even if a scene fits in memory, the 128-bit interface limits the transfer rate to that figure. The combination of a 128-bit bus and GDDR3 memory type is a modest configuration, and the fact pack lists no alternative memory layout. This makes the memory subsystem the most likely limit for high-resolution use, independent of the compute rates on the GPU itself.

Ray Tracing and Feature Set

Ray tracing and tensor-heavy features are not represented in the fact pack. The rtCores and tensorCores fields are both null, meaning no hardware ray tracing core counts and no tensor core counts are recorded. The listed API support is DirectX 11.1 (10_1) and OpenGL 3.3, with Vulkan marked null. The DirectX entry carries a feature level qualifier of 10_1, which means the card exposes DirectX 11.1 APIs but only up to the 10_1 feature level. The Tesla 2.0 architecture provides 96 shading units, 32 texture mapping units, and 8 raster operation units. These are the core building blocks for the visual feature set. Without ray tracing cores or tensor cores, the feature set is limited to the traditional raster pipeline represented by those units. The absence of a Vulkan listing further narrows the software interface available to applications.

Power and Cooling

The power and cooling profile is low. The TDP is 69 W, and the suggested PSU is 250 W. No power connectors are listed for the card. The card occupies a single slot and has a length of 168 mm / 6.6 inches. It is built on TSMC's 40 nm process with 727 million transistors and a die size of 144 mm², yielding a transistor density of 5.0M / mm². The combination of a 69 W TDP and no listed power connector keeps installation simple in systems with modest power supplies. The bus interface is PCIe 2.0 x16. No external power connector requirement is present in the data, and the three display outputs are 1x DVI, 1x HDMI, and 1x VGA.

How It Compares

The nearestRivals list for this GPU is empty. Therefore, there is no rival entry on which to base a per-rival comparison, and no deltaPct values are available. The only position metric in the fact pack is percentileVsAllGpus, set to 50. That places the GT 340 OEM at the midpoint of the all-GPU distribution represented in the database. However, the average benchmark score is 0, and the benchmarks array is empty, so the percentile cannot be cross-checked against measured scores. In product lineage, the entry lists GeForce 200 as the predecessor and GeForce 400 as the successor. The chip is GT215, the architecture is Tesla 2.0, and the generation is GeForce 300. The absence of rival data means any direct comparison to another specific GPU would not be grounded in the fact pack.

Benchmark Performance

The benchmarks field is empty. The average benchmark score is 0. Consequently, there are no measured scores to compare against any other GPU, and no exact percentage deltas can be computed. The performance-relevant numbers that do exist are the fixed-function throughput rates: pixel rate 4.400 GPixel/s, texture rate 17.60 GTexel/s, and FP32 compute at 257.3 GFLOPS. These figures are listed alongside the 96 shading units, 32 TMUs, and 8 ROPs in the fact pack. Pixel rate is the maximum rate at which rasterized pixels can be written, and the figure recorded is 4.400 GPixel/s. Texture rate is the maximum rate at which texture samples can be gathered, and the recorded value is 17.60 GTexel/s. FP32 throughput of 257.3 GFLOPS is the peak single-precision compute rate. The 27.20 GB/s memory bandwidth is the ceiling for data movement. Taken together, these numbers describe a design with modest fill and compute ceilings; exactly where it lands against other GPUs cannot be stated because no benchmark records are present.

Who Should Consider It

Without benchmark scores, the recommendation has to be based on the specification sheet. The GT 340 OEM is listed with 1024 MB of GDDR3 memory and a 27.20 GB/s bandwidth, so it should be considered for use cases that fit within that buffer and transfer rate. Scenes with high resolutions and large textures will be bounded by these memory figures. The 4.400 GPixel/s pixel rate and 17.60 GTexel/s texture rate indicate a raster pipeline suited to modest fill workloads. The 96 shading units and 32 TMUs provide limited shading and texturing resources. The API list is DirectX 11.1 (10_1) and OpenGL 3.3, with Vulkan marked null; software that expects newer APIs or hardware ray tracing is outside the supported feature set. The power envelope is small at 69 W, with a 250 W PSU suggestion and no power connectors required. Display outputs are 1x DVI, 1x HDMI, and 1x VGA. As an end-of-life product, it is a legacy part in the data. The 50th percentile all-GPU placement is the only ranking given, but with an average benchmark score of 0, no measured performance confidence can be attached to it.
