About ATI Radeon HD 4450
The ATI Radeon HD 4450 is an entry-level discrete graphics card from AMD, built on the 55 nm TSMC process with the RV710 chip and TeraScale architecture. It occupies the 50th percentile among all GPUs in the database, with an average benchmark score of 0, indicating it is positioned at the very bottom of the performance hierarchy. The card targets basic desktop use rather than gaming, as its specifications—512 MB of DDR2 memory on a 64-bit bus, 80 shading units, 8 texture mapping units, and 4 render output units—suggest a design focused on minimal power draw and simple output rather than raw throughput.
Benchmark Performance
The data shows that the ATI Radeon HD 4450 delivers a peak FP32 performance of 96.00 GFLOPS, a pixel rate of 2.400 GPixel/s, and a texture rate of 4.800 GTexel/s. These figures place it firmly in the lowest tier of the database, consistent with its 50th percentile ranking. Because the nearestRivals array is empty, there are no direct comparative deltas to cite; however, the absolute numbers themselves reveal the card’s limitations. For context, a modern entry-level card would typically exceed 1,000 GFLOPS, but the HD 4450’s 96.00 GFLOPS is roughly one-tenth of that figure, and its 6.400 GB/s memory bandwidth—a product of the 400 MHz memory clock (800 Mbps effective) and 64-bit bus—further constrains any compute-heavy workload.
The 80 shading units operate at a fixed clock, with no base or boost frequency listed, meaning performance is static under load. The 4 ROPS cap the fill rate at 2.400 GPixel/s, which is sufficient for 720p desktop rendering but inadequate for modern 3D applications. Benchmark results indicate that the card’s average score of 0 reflects its absence from standardized test suites, likely because it fails to meet minimum requirements for contemporary benchmarks. In real-world terms, the HD 4450 would struggle with even light 3D acceleration, and its 512 MB frame buffer is a hard constraint for texture-heavy applications. The 8 TMUs and 4 ROPs are balanced for 2D workloads, but the lack of any reported game-specific scores means the data cannot confirm viability in any specific title.
Ray Tracing and Feature Set
The HD 4450 does not include dedicated ray tracing or tensor cores, as the `rtCores` and `tensorCores` fields are null. This is expected for a TeraScale architecture card from the Radeon R700 generation, which predates hardware-accelerated ray tracing by over a decade. The card supports DirectX 10.1 (with a feature level of 10_1) and OpenGL 3.3, but no Vulkan support is listed. This API set limits the card to older titles and applications; DirectX 10.1 allows for some advanced lighting effects, but it lacks the tessellation and compute shader features of DirectX 11. The absence of Vulkan means no access to modern cross-platform graphics APIs, further restricting compatibility with current software.
The display outputs include 1x DVI, 1x HDMI 1.3a, and 1x DisplayPort 1.0, which provide basic connectivity for monitors and TVs. HDMI 1.3a supports 1080p at 60 Hz, while DisplayPort 1.0 can handle similar resolutions, but neither supports high dynamic range or high refresh rates. The memory type is DDR2, which is an older standard with lower bandwidth compared to GDDR3 or GDDR5; the 6.400 GB/s bandwidth is a significant bottleneck for any 3D workload. The card’s feature set is therefore best described as “legacy,” with no hardware support for modern rendering techniques such as ray tracing, variable rate shading, or mesh shaders. Its 242 million transistors on a 73 mm² die yield a transistor density of 3.3M per mm², which is low by modern standards but reflects the simpler architecture of the era.
Power and Cooling
The ATI Radeon HD 4450 has a thermal design power (TDP) of just 25 W, making it one of the most power-efficient cards in the database. This low TDP means it requires no auxiliary power connectors—the `powerConnectors` field is “None”—and can be powered entirely through the PCIe 2.0 x16 slot. The suggested power supply unit is 200 W, which is a modest requirement that most desktop systems can meet without upgrades. The card is single-slot and has a length of 168 mm (6.6 inches), allowing it to fit in compact chassis. Cooling is not specified in detail, but the low TDP suggests that a simple passive heatsink or small fan would suffice; the data does not list a cooler type, so it must be described qualitatively as a capable air cooler for its thermal envelope.
The power delivery is straightforward: the 25 W TDP ensures that even low-end power supplies can handle the card alongside a basic CPU and drives. The absence of power connectors simplifies installation, as no 6-pin or 8-pin cables are required. The bus interface is PCIe 2.0 x16, which is backward compatible with PCIe 1.0 slots, though bandwidth would be limited. The card’s production status is end-of-life, and it was released on November 17, 2011, a date that places it in the tail end of the R700 generation. The low power draw also means that the card generates minimal heat, which is beneficial for small form factor systems, but the trade-off is the severely limited performance noted earlier.

How It Compares
The nearestRivals array is empty, so the data provides no direct comparative percentages against other GPUs. However, the percentile ranking of 50 places the HD 4450 in the middle of the database, which is misleading because the average benchmark score of 0 indicates it has never been tested in any standardized workload. In practical terms, the card’s 96.00 GFLOPS FP32 performance and 6.400 GB/s bandwidth are orders of magnitude below any modern integrated GPU, which typically offers several hundred GFLOPS and dual-channel memory bandwidth. The 25 W TDP is a defining feature, but it comes at the cost of all performance metrics.
Without rival data, the comparison must rely on architectural context. The card’s 80 shading units and 8 TMUs are identical to what one might find in a low-end laptop GPU of the era, but the 64-bit memory bus cripples effective throughput. The 4 ROPs limit pixel fill to 2.400 GPixel/s, which is insufficient for even 1080p gaming at low settings. The lack of Vulkan and DirectX 11 support means the card cannot run modern titles, and its OpenGL 3.3 support is minimal for creative applications. The HD 4450 is best understood as a legacy display adapter, not a gaming or compute device, and its 50th percentile ranking reflects the database’s inclusion of all GPUs, including those with zero results. For any user considering this card, the data shows it would be outperformed by virtually any post-2015 integrated solution, but no specific rival deltas can be cited from the fact pack.
