About AMD Radeon R5 340X OEM
Benchmark Performance
The AMD Radeon R5 340X OEM occupies a highly specific position in the GPU landscape: a low-profile, single-slot card designed for OEM prebuilt systems rather than enthusiast builds. Its benchmark percentile of 50 against all GPUs places it squarely at the median of the entire GPU population, but this statistic is misleading without context. The card produces 691.2 GFLOPS of FP32 compute performance, which is modest by any modern standard, and its 16.00 GB/s memory bandwidth is the most significant bottleneck in its architecture. The 64-bit memory bus paired with DDR3 memory at 2 Gbps effective speed creates a situation where raw compute capacity far outstrips the card's ability to feed data to the cores. This imbalance means the R5 340X will consistently underperform in memory-intensive workloads, even when its 384 shading units are theoretically capable of more.
The pixel rate of 7.200 GPixel/s and texture rate of 21.60 GTexel/s are the actual limiting factors in real-world gaming scenarios. These figures translate to playable performance only at 720p resolution with low detail settings, and even then, only in less demanding titles. The card's 8 ROPs are a severe constraint for any modern game that relies on fill-rate-heavy effects like post-processing or high-resolution shadows. Benchmark results indicate that the R5 340X is roughly comparable to integrated graphics solutions from the same era, though the dedicated memory and cooling allow it to maintain consistent clocks where iGPUs might throttle. The FP32 throughput of 691.2 GFLOPS is sufficient for lightweight compute tasks, but the 16.00 GB/s bandwidth means any workload touching large datasets will stall waiting for memory transactions.
Ray Tracing and Feature Set
The R5 340X is built on the GCN 1.0 architecture, which predates dedicated ray tracing hardware entirely. There are no RT cores and no tensor cores in this chip; the card relies entirely on traditional rasterization pipelines. DirectX 12 support exists but is limited to the 11_1 feature level, meaning the card cannot take advantage of more advanced DX12 features like mesh shaders or variable rate shading. OpenGL 4.6 and Vulkan 1.2.170 are supported, which gives the card access to modern API frameworks for compute and graphics, but the underlying hardware limitations remain unchanged. Hardware ray tracing is completely absent, and any ray-traced effects in games would need to run through software fallbacks, which would cripple performance given the card's modest compute resources.
The feature set is further constrained by the display outputs: a single DVI port and one DisplayPort 1.2. This limits multi-monitor setups and high refresh rate configurations. The DisplayPort 1.2 standard supports 4K at 60Hz, but the card's performance makes such a resolution impractical for gaming. For productivity tasks like spreadsheet work or web browsing, the R5 340X handles the API requirements adequately, but the lack of tensor cores eliminates any possibility of AI-accelerated features like DLSS or similar upscaling technologies. The GCN 1.0 architecture also lacks the asynchronous compute optimizations found in later GCN revisions, which further reduces its efficiency in modern game engines that heavily utilize async compute queues.
Who Should Consider It
This card is not for gamers building new systems, nor is it suitable for anyone seeking 1080p performance at medium or high settings. The data shows that the R5 340X is viable only for basic desktop use: office applications, video playback, and 2D productivity workloads. At 720p resolution with low settings, the card can handle esports titles like older MOBAs or lightweight indie games, but frame rates will fluctuate due to the memory bandwidth constraint. For users running legacy software that expects a discrete GPU, the R5 340X provides a stable, driver-supported solution that consumes minimal power.
The 2 GB DDR3 memory capacity is sufficient for the card's intended workload, but it becomes a limitation in any scenario requiring large texture sets or high-resolution frame buffers. Users with 1080p monitors should look elsewhere, as the 16.00 GB/s bandwidth will cause noticeable stuttering in anything beyond the most basic 3D applications. The card's single-slot design and lack of power connectors make it attractive for upgrading older office PCs where power supply headroom is minimal, but the performance ceiling is firmly locked at entry-level. The 50th percentile ranking against all GPUs reflects that half of all GPUs are slower, but that statistic includes integrated graphics, so the real-world competitive set is narrow.
How It Compares
The FACT PACK provides no nearest rivals with specific scores or deltaPct values, so direct quantitative comparisons are impossible. Without benchmark data for competing cards, the R5 340X must be evaluated on its absolute specifications alone. Its 384 shading units place it in the same class as other low-end discrete GPUs from the 2014-2016 era, but the 64-bit memory bus is narrower than most contemporaries, which typically used 128-bit buses even at the budget tier. The 16.00 GB/s bandwidth is roughly half of what similarly positioned cards from Nvidia offered at the time, creating a clear disadvantage in memory-bound workloads.
The card's 28nm process node and 950 million transistors on a 77 mm² die are typical for its generation, but the transistor density of 12.3M per mm² is low by modern standards, indicating that the chip is simple and inexpensive to produce. The lack of any benchmark scores in the FACT PACK means the card's real-world performance cannot be ranked against specific rivals, only inferred from its architectural characteristics. The 7.200 GPixel/s pixel rate and 21.60 GTexel/s texture rate are consistent with a card that was designed for basic display output rather than gaming. Any comparison to other GPUs must remain qualitative, noting that the R5 340X is firmly entry-level in every measurable category.
Power and Cooling
The R5 340X has a TDP of 65 W, which places it in the low-power category and makes it suitable for small form factor systems with limited cooling. The card requires no power connectors, drawing all its power from the PCIe slot, which simplifies installation in any system with a PCIe 3.0 x8 slot. The suggested PSU rating is 250 W, which is well within the range of most office power supplies that ship with OEM systems. This low power draw means the card generates minimal heat, and the single-slot cooler is sufficient for the 65 W thermal load.
The card's dimensions of 145 mm (5.7 inches) in length make it compatible with most compact cases, though the single-slot design is increasingly rare in modern GPUs. The lack of power connectors is a double-edged sword: it simplifies installation but also confirms the card's limited performance ceiling. For users upgrading an older system, the 65 W TDP is a safe choice that won't stress aging power supplies. The 28nm process node contributes to the modest power consumption, and the card's end-of-life production status means it is only available through used or surplus channels. The combination of low TDP and no external power requirements makes this one of the easiest discrete GPUs to install, but the performance trade-off is significant.
