AMD Radeon HD 6450 OEM

Benchmark Performance

The AMD Radeon HD 6450 OEM presents a unique case in the benchmark database: its average benchmark score is recorded as 0, and its percentile ranking sits at 50 against all GPUs. This unusual pairing — a zero score with a median percentile — suggests the card occupies a position where it is either untested in the majority of modern workloads or where its results are so uniformly low that they register as negligible. The data provides no nearest rivals, no delta percentages, and no comparative scores, which means the analysis must proceed from the card’s raw architectural specifications rather than from direct benchmark comparisons.

The absence of benchmark data is itself informative. A GPU with a 50th percentile placement but zero average score indicates that the card’s performance profile does not register meaningfully on contemporary testing scales. The FP32 compute throughput of 200.0 GFLOPS places it firmly in the entry-level segment of its era, but without rival scores, the practical implications of this figure remain abstract. The pixel rate of 2.500 GPixel/s and texture rate of 5.000 GTexel/s further delineate its capabilities: these are figures characteristic of a card designed for basic desktop acceleration and legacy gaming, not for modern 3D workloads. The data shows a hardware design where the shading units (160), texture mapping units (8), and render output units (4) form a configuration that prioritizes minimal power draw over computational throughput.

Ray Tracing and Feature Set

The Radeon HD 6450 OEM contains no dedicated ray tracing cores and no tensor cores — the FACT PACK lists both fields as null. This absence is consistent with its TeraScale 2 architecture, which predates any hardware acceleration for ray tracing or AI-assisted rendering. The card’s API support includes DirectX 11.2 (specifically the 11_0 feature level) and OpenGL 4.4, with no Vulkan support listed. For modern applications that rely on DirectX 12 Ultimate features or Vulkan-based rendering paths, this card is categorically incompatible.

The practical consequence of this feature set is that the card cannot participate in any ray-traced workloads, whether in gaming, professional visualization, or compute applications. The absence of tensor cores similarly precludes any DLSS-style upscaling or AI-based frame generation. The HDMI 1.3a output supports basic display connectivity but lacks the bandwidth for high refresh rates at modern resolutions. The display outputs — 1x DVI, 1x HDMI 1.3a, and 1x VGA — reflect the connectivity standards of its 2011 release period, offering legacy compatibility rather than modern display features. The DirectX 11.2 support is nominally present, but the 11_0 feature level means it cannot utilize the higher-tier features of the 11.2 specification.

How It Compares

The FACT PACK lists no nearest rivals, no comparative scores, and no delta percentages. This absence of comparative data forces the analysis to rely on the card’s internal specifications and its historical context. The card’s predecessor is listed as Evergreen, and its successor as Southern Islands, placing it within the Northern Islands generation (HD 6400 series). The 40 nm process node and 370 million transistors on a 67 mm² die yield a transistor density of 5.5M per mm² — a figure that was modest even at its launch.

Without rival data, the position of this card must be understood through its architectural lineage. The TeraScale 2 architecture was AMD’s second generation of unified shader designs, and the HD 6450 OEM represents the most basic configuration within that family. Compared to the Evergreen generation that preceded it, the Northern Islands generation offered incremental improvements in power efficiency and feature support, but the HD 6450 OEM’s 18 W TDP and 512 MB memory capacity indicate it was designed to occupy the absolute bottom of the product stack. Against the Southern Islands generation that followed, the card lacks the Graphics Core Next (GCN) architecture improvements that would come to define AMD’s subsequent GPUs. The data shows a card that was end-of-life at the time of its release, serving primarily as an OEM solution for basic office and media center systems.

Power and Cooling

The thermal design power (TDP) of 18 W is remarkably low, even by the standards of its generation. This figure allows the card to be entirely passive in most implementations, requiring no auxiliary power connectors — the FACT PACK lists "None" for power connectors. The suggested power supply is 200 W, which is a conservative recommendation that reflects the card’s minimal draw. A single-slot cooling solution suffices, and the card’s physical dimensions of 168 mm (6.6 inches) in length make it compatible with virtually any chassis, including small form factor systems.

The power characteristics of this card are its primary differentiator. An 18 W TDP means the card draws less power than many CPU coolers, and the absence of power connectors simplifies installation in pre-built systems. The 200 W PSU recommendation is not a limitation but rather a floor — most systems from the card’s era would have shipped with power supplies at or above this rating. The PCIe 2.0 x16 bus interface provides sufficient bandwidth for the card’s 8.528 GB/s memory bandwidth, and the lack of a supplemental power requirement means the card can be installed in legacy systems without upgrade considerations. The 40 nm process node contributes to this efficiency, though the transistor density of 5.5M per mm² indicates that the design did not push the limits of the manufacturing process.

Who Should Consider It

The benchmark data provides no scores to ground resolution or settings recommendations, so the analysis must derive from the card’s raw specifications. The 200.0 GFLOPS FP32 performance and 8.528 GB/s memory bandwidth are figures that suggest the card is suitable only for workloads that predate its release. For modern gaming at 1080p, the card would be inadequate for any title requiring DirectX 11 features, and even older DirectX 9 games would likely struggle at medium settings. The 512 MB VRAM capacity is the primary constraint — modern textures require significantly more memory, and even the lightest contemporary titles would exceed this limit.

The card’s most plausible use case is as a display adapter for basic productivity tasks: office applications, web browsing, and video playback. For these workloads, the card’s 2.500 GPixel/s pixel rate and 5.000 GTexel/s texture rate are sufficient. The HDMI 1.3a output supports 1080p video playback, and the VGA output allows connection to legacy monitors. The card is not suitable for any form of modern gaming, ray tracing, or GPU-accelerated compute. The DirectX 11.2 support is nominally present, but the 11_0 feature level restricts it to the most basic DirectX 11 functionality, which many games require as a minimum. The data indicates a card that should be considered only for systems where the primary requirement is display output, not 3D acceleration.

Memory Subsystem

The memory configuration consists of 512 MB of GDDR3 memory on a 64-bit bus, yielding a bandwidth of 8.528 GB/s. The memory clock is listed as 533 MHz, with an effective data rate of 1066 Mbps. This configuration is severely bandwidth-limited by modern standards — even entry-level cards from the same era typically offered 128-bit buses and higher memory capacities. The 64-bit bus width means that the card’s memory bandwidth is insufficient for high-resolution textures or large frame buffers.

The implications of this memory subsystem are most pronounced at high resolutions. At 1080p, the 512 MB capacity is immediately exhausted by modern game textures, and the 8.528 GB/s bandwidth becomes a bottleneck for any shader workload that requires frequent memory access. The FP32 compute rate of 200.0 GFLOPS is similarly constrained by the memory subsystem — the card cannot feed its own compute units fast enough to achieve sustained performance. The GDDR3 memory type, while adequate for the card’s era, offers significantly lower bandwidth per clock than the GDDR5 memory that was already available in higher-end cards of the same generation. The 64-bit bus width is the fundamental limitation: it halves the memory bandwidth compared to a 128-bit implementation, and this constraint affects all workloads equally, from texture sampling to vertex processing.

The pixel rate of 2.500 GPixel/s and texture rate of 5.000 GTexel/s are directly tied to the memory subsystem. With only 4 ROPs, the card cannot perform more than 4 pixel writes per clock, and the 8.528 GB/s bandwidth determines how quickly those pixels can be written to the frame buffer. For a card with a 200 W PSU recommendation and 18 W TDP, the memory subsystem represents a deliberate trade-off: minimal power consumption at the cost of memory throughput. The 512 MB capacity is the smallest available in the HD 6400 series, and the 64-bit bus is the narrowest configuration offered. This design philosophy — maximizing power efficiency at the expense of performance — makes the card suitable only for the most basic display tasks, and the data confirms that it cannot serve as a gaming or compute accelerator in any meaningful capacity.
