AMD Radeon R7 450 OEM

The AMD Radeon R7 450 OEM is an end-of-life, single-slot GPU released on 2016-06-29, built on TSMC's 28 nm process with GCN 1.0 architecture and the Cape Verde chip. It contains 1,500 million transistors on a 123 mm² die, for a transistor density of 12.2M / mm². The data set lists no benchmark entries, no nearest rivals, and an average benchmark score of 0; the only aggregate placement is the 50th percentile of all GPUs. It uses 512 shading units, 32 TMUs, and 16 ROPs, with listed throughput figures of 947.2 GFLOPS FP32, 29.60 GTexel/s, and 14.80 GPixel/s.

Benchmark Performance

Benchmark results are not present for this card. The `benchmarks` field is empty, the `nearestRivals` field is empty, and the average benchmark score is 0. That means no measured game score can be reported, and no exact percentage deltas against other GPUs can be calculated. The only relative data point is the 50th percentile position in the database's all-GPU distribution. That places the card in the middle of the aggregate GPU pool, but it should not be read as a game-specific performance score.

Without direct benchmark scores, the available compute and fill-rate figures are the main performance indicators. The card is rated for 947.2 GFLOPS of FP32 compute, 29.60 GTexel/s of texture fill, and 14.80 GPixel/s of pixel fill. These are raw throughput numbers, not application frame rates. They describe the maximum rate at which shader operations, texture samples, and pixel writes can be processed. The 512 shading units and 32 TMUs feed into those rates, while the 16 ROPs determine the pixel output ceiling. No base or boost clock is listed for the GPU; the only clock recorded in the specification is the memory clock. The data also does not list an FP16 rate, so half-precision compute cannot be assessed from this record.

The 50th percentile standing does provide a broad comparison point. It indicates that, across all GPUs in the database, this model sits at the midpoint. That is consistent with a part that is not a high-end performer and not at the very bottom of the field. Because there are no nearest rivals, there is no way to state whether it is ahead of or behind specific competing cards by a percentage. The absence of direct rivals means the relative analysis normally expected from a benchmark page cannot be completed with this data. Raw specification limits are the only available basis for setting expectations.

Ray Tracing and Feature Set

The data set lists no RT core count and no tensor core count. No hardware ray-tracing or tensor/AI acceleration specifications are available for this GPU, so it should not be assumed to have dedicated ray-tracing cores. The architecture is GCN 1.0, and the generation is Arctic Islands (R7 400). It sits between the Pirate Islands generation and the Polaris generation.

API support is listed as DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The DirectX entry is specifically labeled 12 (11_1), meaning the DirectX 12 API is supported with an 11_1 feature level. Vulkan 1.2.170 and OpenGL 4.6 provide modern cross-platform graphics API options. These are the available API facts; no additional feature-level details are provided.

Display outputs are 1x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2. This gives the card multiple connection types for display connectivity. No tensor core count means that machine-learning acceleration and AI-based features cannot be evaluated from this specification sheet. The feature set is otherwise defined by the GCN 1.0 architecture, the Cape Verde chip, and the listed API support.

Memory Subsystem

The memory configuration consists of 2 GB of GDDR5 on a 128-bit bus. The memory clock is 1125 MHz, which is described as 4.5 Gbps effective. Those figures combine to produce 72.00 GB/s of memory bandwidth.

For a GPU with 512 shading units and 16 ROPs, 72.00 GB/s is the data path between the GPU and its frame buffer. The 2 GB capacity is a hard limit on how much texture and rendered data can be stored locally on the card. At high resolutions, this becomes a significant constraint. A larger capacity and higher bandwidth are typically needed to keep high-resolution, high-detail scenes feeding smoothly to the ROPs. The listed 2 GB capacity and 72.00 GB/s bandwidth set a ceiling for memory-intensive workloads.

The 128-bit bus width is part of that ceiling. The memory clock and bus width are the two factors that define bandwidth: 1125 MHz GDDR5 across 128 bits yields 72.00 GB/s. That is the fixed rate at which pixel writes and texture reads can pass through the memory subsystem. Scenes that exceed the 2 GB frame buffer will hit capacity limits; scenes that require high memory throughput may hit bandwidth limits. Lower resolutions and lighter settings place less pressure on both capacity and bandwidth, which is consistent with the card's mid-pack aggregate position.

Who Should Consider It

The Radeon R7 450 OEM is best suited to systems where a modest amount of GPU capability is acceptable. The 50th percentile placement, combined with 2 GB of memory and 72.00 GB/s of bandwidth, points toward lower-resolution, lower-detail workloads rather than high-resolution rendering. The FP32 rate of 947.2 GFLOPS and the pixel rate of 14.80 GPixel/s are not top-tier figures. They indicate a card that can handle basic graphics work and less demanding applications, but not one designed for maximum graphical load.

Because it is named as an OEM product, it is most likely to appear in prebuilt systems. Its end-of-life status means it is no longer produced. The specification list provides no benchmark scores, so exact frame-rate behavior cannot be verified from this data. Decisions should be based on the raw constraints: 2 GB VRAM, 72.00 GB/s bandwidth, and mid-pack aggregate standing. For workloads that fit within those limits, the card can function as a basic display adapter and light graphics processor. For high-resolution or high-detail rendering, the memory capacity and bandwidth become the primary limiting factors. The 50th percentile position reinforces the idea that this is not a performance-oriented part.

Power and Cooling

The Radeon R7 450 OEM has a TDP of 65 W and a suggested PSU rating of 250 W. The power connectors field is None, meaning no auxiliary power cables are required for installation beyond what the system already provides. The card is single-slot, so it occupies a single expansion slot in the chassis. The bus interface is PCIe 3.0 x16.

The 65 W TDP is modest, and the single-slot form factor is consistent with a low-power cooling design. No length, height, or width values are included in the specification, so physical clearance cannot be confirmed from the data. The only physical form factor information is the single-slot width designation. The absence of power connectors simplifies installation in systems where additional GPU power cabling is not available. The suggested 250 W PSU is the system-level recommendation provided in the spec sheet. With a 65 W TDP and no additional power connectors, the card does not demand a high-end power supply. The PCIe 3.0 x16 interface is the data connection to the host system.
