AMD Radeon HD 7450M

The AMD Radeon HD 7450M is a 40 nm mobile graphics processor built on the TeraScale 2 architecture, using the Seymour chip fabricated by TSMC. The die measures 67 mm² and contains 370 million transistors, giving a transistor density of 5.5M per square millimeter. It was released on 2012-01-06 as part of the London generation of the HD 7400M series, succeeding Vancouver and preceding Solar System. The production status is end-of-life, and the bus interface is PCIe 2.0 x16.

Benchmark Performance

The database entry for the AMD Radeon HD 7450M contains no benchmark scores, and the nearestRivals field is empty. The average benchmark score is recorded as 0, which confirms the absence of measured performance data. The only ranking metric present is percentileVsAllGpus, which places this GPU at the 50th percentile of all GPUs tracked in the database. That median standing, combined with the lack of any rival comparison data, means the performance picture must be inferred from the raw specification set rather than from measured workloads.

The compute resources are modest. The GPU has 160 shading units, 8 texture mapping units, and 4 raster operation units. The FP32 throughput is 240.0 GFLOPS, the texture rate is 6.000 GTexel/s, and the pixel rate is 3.000 GPixel/s. These figures are consistent with an entry-level mobile part designed for basic rendering tasks. The memory subsystem uses 1024 MB of DDR3 on a 64-bit bus, with a memory clock of 900 MHz (1800 Mbps effective) and a bandwidth of 14.40 GB/s. The 64-bit bus width is a key limiter; it caps the amount of data the GPU can move per cycle, and the 14.40 GB/s bandwidth is low relative to the broader GPU population tracked in this database.

Because no nearestRivals data is provided, there are no deltaPct values to report. The 50th percentile position, however, suggests that this GPU sits exactly in the middle of the database's performance distribution. That may seem surprising for a part with such a narrow memory bus, but the database's all-GPU percentile includes many older and lower-end integrated parts. The 240.0 GFLOPS FP32 rate and 6.000 GTexel/s texture rate are the strongest compute indicators available, and they point to a GPU that can handle low-resolution 3D workloads but will struggle with anything demanding.

In the absence of benchmark scores, the texture fillrate and pixel fillrate are the closest proxies for rasterization performance. The 6.000 GTexel/s texture rate and 3.000 GPixel/s pixel rate, when paired with the 14.40 GB/s memory bandwidth, define a narrow throughput envelope. The data shows a part that is balanced toward compute over memory, which is typical of a low-power mobile GPU from this era. The 50th percentile ranking should be read with caution, as it is a relative position across all GPUs and not a measured performance score. The FP32 throughput of 240.0 GFLOPS, spread across 160 shading units, gives a per-unit compute rate that is adequate for simple shaders but quickly saturates when pixel or vertex workloads become complex. The 4 ROPs and 8 TMUs further constrain the GPU to low fillrate scenarios, meaning that even modest resolutions with high texture detail will exceed the available throughput.

Ray Tracing and Feature Set

The FACT PACK lists no ray tracing cores and no tensor cores for the AMD Radeon HD 7450M. Both fields are null, which indicates that this GPU does not include dedicated hardware for ray tracing or AI-accelerated tensor operations. The architecture is TeraScale 2, a shader-based design that does not incorporate the dedicated ray tracing and tensor hardware found in later GPU generations.

The API support is limited to DirectX 11.2 (11_0) and OpenGL 4.4. Vulkan is not supported, as the vulkan field is null. The DirectX 11.2 (11_0) support means the GPU can run applications built for the DirectX 11 feature level, but it cannot leverage newer DirectX 12 or Vulkan features. OpenGL 4.4 support allows for a range of cross-platform graphics workloads, but the absence of Vulkan closes off modern low-overhead rendering paths. The feature set is therefore defined by the capabilities of the DirectX 11.2 (11_0) and OpenGL 4.4 APIs, with no path to hardware-accelerated ray tracing or tensor-based features.

The display outputs are listed as "Portable Device Dependent," meaning the actual connectors are determined by the laptop or mobile device in which the GPU is installed. There are no fixed display output specifications in the data. The bus interface is PCIe 2.0 x16, which provides the connection to the host system. The lack of RT and tensor cores, combined with the DirectX 11.2 (11_0) API ceiling, defines the feature set as one built for conventional rasterized rendering rather than for ray-traced or AI-enhanced graphics. The 40 nm process node and TeraScale 2 architecture also indicate a design that predates the unified shading and compute-heavy feature sets of more recent GPUs.

Power and Cooling

The thermal design power for the AMD Radeon HD 7450M is 7 W. This is a very low power envelope, which has direct implications for cooling requirements. The data does not specify any power connectors, and no suggested PSU is listed. For a 7 W GPU, the power draw is well within what a mobile motherboard can supply through the PCIe 2.0 x16 slot, so external power connectors are unnecessary. The slot width field is null, and the dimensions (length, height, width) are all null, so the physical size of the card is not recorded.

The display outputs being "Portable Device Dependent" reinforces that this is a mobile GPU rather than a standalone expansion card. The 7 W TDP means that a passive cooling solution or a very small heatsink is likely sufficient, but the data does not confirm any specific cooler design. The absence of a suggested PSU rating is consistent with the low power draw. Desktop GPUs with higher TDPs typically require a PSU recommendation, but a 7 W part does not place meaningful load on a power supply. The PCIe 2.0 x16 bus interface is the only power delivery path mentioned in the data. For system integrators, the 7 W figure is the key planning number: it indicates that thermal management is trivial and that no additional power cabling is needed. The 40 nm process node, while not state-of-the-art even at release, contributes to the low power draw by keeping switching losses modest at the 900 MHz memory clock and the GPU's internal clock rates.

Who Should Consider It

The AMD Radeon HD 7450M is positioned at the 50th percentile of all GPUs in the database, but that ranking is not backed by any benchmark scores in the data. The raw specifications provide the only guidance for potential users. The 240.0 GFLOPS FP32 throughput, 6.000 GTexel/s texture rate, and 3.000 GPixel/s pixel rate indicate a GPU that is suitable for basic display output, 2D applications, and very light 3D workloads. The 14.40 GB/s memory bandwidth and 64-bit bus are the primary bottlenecks for any memory-intensive task.

For gaming, the DirectX 11.2 (11_0) support means that older titles built for DirectX 11 or earlier can run, but the compute and memory figures strongly suggest that only low resolutions and low detail settings are feasible. The 1024 MB memory capacity is sufficient for small framebuffers, but the 64-bit bus and 14.40 GB/s bandwidth will limit texture streaming and high-resolution assets. Users seeking to play modern 3D games at high settings will not find the necessary performance in this data. The 50th percentile ranking across all GPUs suggests it is not a bottom-tier part, but it is also far from the top of the distribution.

For non-gaming use, the 7 W TDP and "Portable Device Dependent" display outputs make this GPU a candidate for thin-and-light laptops where power efficiency is prioritized. The lack of Vulkan support and the absence of ray tracing and tensor cores mean that any workload relying on those features is out of reach. The data supports a recommendation for basic productivity, video playback, and legacy DirectX 11 applications at modest resolutions. The 160 shading units and 8 TMUs can handle simple shader programs and basic texture mapping, but the 4 ROPs limit the pixel throughput to 3.000 GPixel/s, which is the hard ceiling for fillrate-bound scenes. The 240.0 GFLOPS FP32 rate is the upper bound for compute-style workloads, and that number is low enough to exclude physics simulation, machine learning inference, or any GPU-accelerated compute task beyond the simplest filters. Users who need higher resolution, higher detail, or any form of modern graphics acceleration should look at GPUs with more shading units, a wider memory bus, and higher bandwidth than the 14.40 GB/s recorded here.
