About AMD Radeon HD 7450 OEM
The AMD Radeon HD 7450 OEM is a 40 nm TeraScale 2 graphics card built around the Caicos chip. It belongs to the Southern Islands (HD 7400) generation, was released on 2012-01-04, and is recorded as end-of-life. The data set lists no nearestRivals and an average benchmark score of 0, so this entry focuses on the hardware characteristics and what they mean for the workloads this card can actually handle.
Benchmark Performance
The benchmark portion of the data set contains no nearestRivals entries, so no rival names, scores, or deltaPct values are available to quote here. The only ranking fields are percentileVsAllGpus at 50 and avgBenchmarkScore at 0. A 50th percentile is a midpoint position in the database, but because the average benchmark score is recorded as 0, that percentile is not backed by an observed test run. It is best treated as a placement marker rather than as a performance measurement.
What can be analyzed are the throughput specifications. The card is rated at 200.0 GFLOPS of FP32 compute, 2.500 GPixel/s pixel fill, and 5.000 GTexel/s texture fill. These rates come from 160 shading units, 8 TMUs, and 4 ROPs. These are small figures for a discrete GPU, and they indicate a very limited execution engine. The memory side is equally restrained: 512 MB of GDDR3 on a 64-bit bus produces 8.528 GB/s of bandwidth. The balance between 200.0 GFLOPS and 8.528 GB/s is typical of a low-end OEM part, where neither compute nor memory bandwidth can compensate for the other. Because the nearestRivals list is empty, no exact percentage deltas can be shown against any named competitor. The performance conclusion therefore rests on the raw hardware rates: this is a low-throughput card, and no benchmark average in the record contradicts that.
Who Should Consider It
The HD 7450 OEM is for systems that need basic graphics output rather than high-end 3D acceleration. Its 18 W TDP, no power connectors, single-slot width, and 168 mm / 6.6 inch length make it a straightforward install in a desktop PCIe 2.0 x16 slot. The 512 MB framebuffer and 8.528 GB/s bandwidth set a hard ceiling for workloads: at high resolutions, both capacity and data movement will be exhausted quickly. In practice, that means reduced texture quality and lower resolutions for any 3D application. The pixel rate of 2.500 GPixel/s and texture rate of 5.000 GTexel/s reinforce the same verdict: this card is not built for effects-heavy rendering.
The supported API set also defines who should consider it. With DirectX 11.2 (11_0), OpenGL 4.4, and no Vulkan listed, it can handle older or lighter software, but modern API-only titles are not in its feature set. For desktop use, the 1x DVI and 1x HDMI 1.3a outputs cover typical single- or dual-display configurations. The card's best environment is a pre-existing OEM desktop where the task is 2D output, video display, or light legacy 3D content. The hardware numbers point to a display adapter first, not a gaming card.
Memory Subsystem
Memory on the HD 7450 OEM is 512 MB of GDDR3, connected over a 64-bit bus. The memory clock is 533 MHz, with an effective data rate of 1066 Mbps, and the resulting bandwidth is 8.528 GB/s. These are exact values from the data set, and they are the defining constraint of the card. A 64-bit bus is narrow; combined with GDDR3, it produces a bandwidth level that will saturate quickly during texture reads or framebuffer writes.
Capacity is also limited. 512 MB cannot hold the texture sets and geometry buffers expected in modern high-resolution rendering, so anything beyond modest settings will be restricted. The 8.528 GB/s bandwidth means even if the 160 shading units could compute more, the memory system would be the bottleneck. The pixel rate of 2.500 GPixel/s is another hard ceiling: the ROPs can only write 2.500 GPixel/s, so high resolutions will press against this limit. The 1066 Mbps effective memory speed is not high enough to rescue those situations. For high-resolution use, the combination of 512 MB, 64-bit bus, and 8.528 GB/s is a wall, not a gradual falloff.

How It Compares
No nearest rivals are listed in the data set, so no named comparison and no deltaPct values are available. The only ranking evidence is percentileVsAllGpus at 50 and avgBenchmarkScore at 0. Because the average score is 0, the percentile cannot be interpreted as a measured performance result. The predecessor and successor fields identify Northern Islands and Sea Islands as adjacent generations, not as performance rivals. Without nearestRivals entries, any percentage delta would be unsupported.
Power and Cooling
The power profile of the HD 7450 OEM is very low. The TDP is 18 W, and the data set lists no power connectors. The suggested PSU is 200 W, which is a modest system requirement. The card is a single-slot design with a length of 168 mm / 6.6 inches. These figures mean external power cabling is not needed. The low 18 W TDP keeps cooling simple; the single-slot form factor is sufficient for the heat that such a power draw would generate. The short length also allows it to fit in smaller desktop cases. Installation does not involve routing auxiliary power cables, since the card uses a PCIe 2.0 x16 interface and has no power connectors.
Ray Tracing and Feature Set
The data set lists no RT cores and no tensor cores, so hardware-accelerated ray tracing and tensor operations are not part of this GPU's feature set. The architecture is TeraScale 2, which predates such blocks. The feature set instead centers on 160 shading units, 8 TMUs, and 4 ROPs. These units deliver a pixel rate of 2.500 GPixel/s, a texture rate of 5.000 GTexel/s, and 200.0 GFLOPS of FP32 compute. No FP16 throughput is recorded. On the API side, the card supports DirectX 11.2 (11_0) and OpenGL 4.4. Vulkan support is not listed. Display connectivity is 1x DVI and 1x HDMI 1.3a. The absence of RT and tensor cores, combined with the limited API list, gives this card an older feature profile rather than a modern accelerated compute feature set.
