About NVIDIA GRID K340

The NVIDIA GRID K340 is a dual-slot, end-of-life accelerator built for virtualized graphics workloads, not consumer gaming. Based on the 28 nm Kepler architecture and the GK107 chip, it houses 1,270 million transistors on a 118 mm² die, resulting in a transistor density of 10.8M per mm². Its benchmark percentile against all GPUs stands at 50, placing it in the median position of the performance distribution, though its average benchmark score is recorded as zero, indicating a lack of standardized performance data in this database.

Benchmark Performance

The data for the GRID K340 presents a unique challenge: there are no benchmark scores, no nearest rivals, and no delta percentages to analyze. The average benchmark score is 0, and the nearestRivals array is empty. This means a direct performance comparison against specific competing products is impossible from the available facts. The only quantitative measure is its percentile rank of 50, which signals that, in the broader context of all GPUs ever tested, it sits exactly at the midpoint. This is not a measure of raw speed but of relative standing; half of all GPUs are faster and half are slower, a statistical artifact rather than a definitive performance verdict.

Theoretical compute figures provide the only insight into its raw capabilities. The card delivers 732.7 GFLOPS of FP32 compute, a figure derived from its 384 shading units. Its pixel fill rate is 7.632 GPixel/s, and its texture rate is 30.53 GTexel/s, the latter driven by 32 texture mapping units. These numbers suggest a design focused on throughput for virtual desktop infrastructure rather than latency-sensitive frame rendering. The lack of any comparative data means that interpreting these absolute values requires caution; they are the only quantitative anchors available, but without rivals, the analysis stops at describing the hardware’s theoretical limits.

Ray Tracing and Feature Set

This accelerator does not include dedicated ray tracing hardware. The RT cores field is null, and similarly, there are no tensor cores present. This absence is consistent with its Kepler architecture, which predates the introduction of these specialized units. Consequently, any real-time ray tracing workload is unsupported at the hardware level. The feature set is instead defined by its API support, which is broad for its era. It supports DirectX 12 (11_0), meaning it can run applications built for DirectX 11 but lacks the full feature set of DirectX 12 Ultimate. OpenGL 4.6 and Vulkan 1.2.175 are also supported, offering compatibility with a range of professional and compute applications that leverage these cross-platform APIs.

The lack of tensor cores also means that any AI-accelerated features, such as deep learning super sampling or other neural network-based enhancements, are not available. The GRID K340’s feature profile is thus fundamentally about standard graphics rasterization and compute via traditional shader pipelines. For a product aimed at virtualized environments, this is a limiting factor for modern workloads that increasingly rely on hardware-accelerated AI and ray tracing, but it was a standard configuration for a GPU launched in 2013.

Memory Subsystem

The memory configuration is defined by a 1024 MB (1 GB) frame buffer of GDDR5 type. This is connected via a 128-bit memory bus, which is the interface width for data transfer. The effective memory clock is 5 Gbps, and when combined with the bus width, this yields a maximum bandwidth of 80.00 GB/s. This bandwidth figure is a critical constraint. For high-resolution rendering, particularly at 4K or multi-monitor setups, a larger memory pool and higher bandwidth are essential to avoid bottlenecks. A 1 GB buffer is now considered insufficient for modern game textures and high-resolution assets, which can easily exceed this capacity.

The 80.00 GB/s bandwidth is a moderate figure for the time of release, but it is a severe limitation for contemporary use. The combination of a 128-bit bus with 1 GB of VRAM suggests the card was never intended for high-fidelity gaming. Instead, this configuration points toward a use case where each virtual machine receives a small slice of memory for basic desktop composition and light 2D/3D acceleration. The data shows a subsystem that is adequate for its original purpose but is not competitive for any current high-resolution gaming or content creation scenario.

Power and Cooling

The GRID K340 has a thermal design power (TDP) of 225 W, which is a substantial power draw for a card that offers no display outputs. The board is dual-slot in width and has a length of 267 mm (10.5 inches). To power this, it requires a single 8-pin power connector. The system’s power supply is recommended to be a 550 W unit, which provides a baseline for the minimum system requirement. This TDP means that, despite its modest compute performance today, it generates significant heat and requires adequate cooling, particularly in a dense server environment where multiple such cards might be installed.

The absence of display outputs is a defining characteristic. This is not a card meant for direct connection to a monitor. The 225 W TDP is primarily for compute and rendering tasks, and the dual-slot cooler must dissipate that heat effectively. The recommended 550 W PSU is a system-level guideline, ensuring that the rest of the platform has enough headroom for the card’s peak consumption. For any potential deployment, the physical dimensions and power requirements are fixed constraints that cannot be ignored.

How It Compares

This section cannot be written with specific rival comparisons because the nearestRivals array is empty. There are no alternative GPUs listed, no performance deltas, and no names to analyze. The percentile rank of 50 provides the only contextual data point, but it is a global statistic, not a direct comparison. Therefore, any attempt to position the GRID K340 against a specific competitor would be speculation, which is not permitted by the data.

The absence of rivals is itself a data point. It indicates that this product does not fit into a conventional comparison framework, likely because its target market is so specific that the database lacks entries for comparable virtualization accelerators. The only valid statement is that, relative to the entire GPU landscape, it is exactly average in percentile terms, but this is not a substitute for a head-to-head comparison. Without a named rival, the analysis must rest on the absolute specifications and the global percentile.

Who Should Consider It

The GRID K340 is not a candidate for any current gaming or high-performance desktop workload. Its 1 GB memory and 80.00 GB/s bandwidth are far too limited for modern game resolutions and texture detail. The 732.7 GFLOPS FP32 performance is similarly insufficient for demanding compute tasks. The lack of RT and tensor cores further disqualifies it for any modern feature-rich application.

The only plausible scenario for considering this hardware is a legacy virtual desktop infrastructure deployment where the software stack is specifically optimized for Kepler-era GPUs. In such an environment, the 384 shading units could provide basic acceleration for office productivity, 2D applications, and light video playback. The PCIe 3.0 x16 interface ensures it can be installed in older servers. However, the 225 W TDP and the need for a 550 W PSU make it an inefficient choice for that purpose. The data suggests it is a product whose utility has passed; it is end-of-life and offers no compelling performance or efficiency advantage for any modern use case. It should only be considered by those with a specific, legacy hardware requirement that cannot be met by any other means.
