AMD Radeon HD 7750M

The AMD Radeon HD 7750M is a mobile graphics processor built on the GCN 1.0 architecture, using the Chelsea chip. Fabricated by TSMC on a 28 nm process, it packs 1,500 million transistors into a 123 mm² die, yielding a transistor density of 12.2 million per square millimeter. This part belongs to the London generation (HD 7700M) and is classified as an IGP (integrated graphics processor) with a slot width of IGP. The database places this GPU at the 50th percentile of all tracked GPUs, indicating a median performance position, though its average benchmark score is recorded as 0. Released on April 23, 2012, it is now marked as end-of-life.

Benchmark Performance

The Radeon HD 7750M delivers a peak FP32 compute throughput of 588.8 GFLOPS, a figure that defines its general-purpose compute capability. Its pixel rate is 9.200 GPixel/s, and its texture rate is 18.40 GTexel/s, derived from 16 ROPs and 32 TMUs respectively. With 512 shading units, the GPU's theoretical output is modest by modern standards. The database records an average benchmark score of 0 for this part, meaning no synthetic test scores have been logged in the current dataset. However, its 50th percentile ranking against all GPUs suggests that when it was active, it performed at the median of the tracked population. Without nearest rival data, the exact percentage deltas cannot be calculated, but the raw throughput numbers indicate a part designed for entry-level or mainstream mobile tasks rather than high-end gaming. The 588.8 GFLOPS figure is a theoretical ceiling; real-world performance would be lower due to memory bandwidth constraints. The pixel rate of 9.2 GPixel/s implies a fillrate that can handle standard display resolutions, but not high-refresh or multi-monitor setups. The texture rate of 18.40 GTexel/s, combined with the 32 TMUs, suggests adequate texture filtering for its intended segment, though it will bottleneck on complex shader workloads.

Memory Subsystem

The memory subsystem is built around a 1024 MB (1 GB) frame buffer of GDDR5 memory, connected via a 128-bit bus. The memory clock runs at 1000 MHz, which translates to a 4 Gbps effective data rate. This configuration yields a total bandwidth of 64.00 GB/s. For high-resolution workloads, this bandwidth is a limiting factor; 64 GB/s is sufficient for moderate textures but will struggle with larger, more complex scenes that demand higher data throughput. The 128-bit bus width also constrains the amount of data that can be moved per clock cycle, making the card more suitable for moderate resolutions and detail settings. The 1 GB capacity is adequate for the era it was released, but modern titles with high-resolution texture packs will exceed this allocation quickly. The 4 Gbps effective memory speed is a standard for GDDR5 of that generation, but the 128-bit bus halves the potential bandwidth compared to wider buses. For a mobile IGP, this bandwidth is reasonable, but it caps the GPU's ability to feed its 512 shading units efficiently. At high resolutions, the 64.00 GB/s ceiling becomes the primary bottleneck, forcing the GPU to rely on compression techniques to maintain playable frame rates.

Power and Cooling

The Radeon HD 7750M has a thermal design power (TDP) of 28 W, which is exceptionally low for a GPU, reflecting its mobile and integrated nature. Because it is classified as an IGP (integrated graphics processor) with a slot width of IGP, it is designed to be soldered onto a motherboard or integrated into a portable device rather than installed as a discrete expansion card. Consequently, the FACT PACK lists no power connectors and no suggested PSU requirement. The absence of these fields indicates that the GPU draws its power directly from the system's main power delivery, eliminating the need for auxiliary PCIe power cables. The low TDP also means that cooling requirements are minimal, allowing for passive or low-profile cooling solutions in thin laptops. The bus interface is PCIe 2.0 x16, which is compatible with the integrated design. The 28 W TDP is a key differentiator, as it allows the GPU to operate within the thermal envelope of a laptop chassis without dedicated cooling fans, or with a single small fan. The lack of a suggested PSU further confirms that this is not a discrete card requiring a separate power supply. This power profile is a direct consequence of the 28 nm process and the relatively low transistor count, which keeps leakage and switching losses in check.

How It Compares

The dataset provides no nearest rivals for the AMD Radeon HD 7750M, so direct comparative deltas against competing GPUs are not available. Its position is instead defined by its 50th percentile rank among all GPUs tracked in the database, placing it squarely in the middle of the performance distribution. In terms of lineage, the HD 7750M succeeds the Vancouver generation and is succeeded by the Solar System generation, indicating its place in AMD's mobile product timeline. The 28 nm process and GCN 1.0 architecture are shared with its immediate family, but without rival scores, the analysis must rely on absolute specifications. The 588.8 GFLOPS FP32 throughput and 64.00 GB/s bandwidth place it in the entry-to-midrange segment of its time, but the lack of benchmark scores prevents a more granular ranking. The 50th percentile is a useful anchor: it means that half of the GPUs in the database are faster and half are slower, which is a neutral standing. Compared to its predecessor and successor, it occupies a middle ground, but the absence of deltaPct values means we cannot quantify the generational leap. The lack of rival data also means we cannot state whether it outperforms or underperforms specific competing parts, leaving its exact competitive standing open to interpretation based on its percentile alone.

Ray Tracing and Feature Set

The Radeon HD 7750M does not include dedicated ray tracing cores or tensor cores, as these fields are listed as null in the specifications. This means hardware-accelerated ray tracing is not supported, and any ray tracing workloads would fall back to compute shaders, which is inefficient given the 588.8 GFLOPS FP32 limit. On the API front, the GPU supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The DirectX 12 support at the 11_1 feature level allows for modern API usage, though with a feature set that predates full DX12 Ultimate capabilities. Vulkan 1.2.170 provides a cross-platform low-level API, and OpenGL 4.6 covers legacy compatibility. The display outputs are marked as "Portable Device Dependent," meaning the actual connectors vary by the laptop or device it is integrated into. The production status is end-of-life, and the release date is April 23, 2012, indicating this is a legacy part. Without tensor cores, any machine learning or AI-accelerated features are unavailable, and without RT cores, ray-traced effects are out of reach. The API support does allow for modern driver-level features, but the hardware is firmly rooted in the pre-RT era. The combination of DirectX 12 (11_1) and Vulkan 1.2.170 ensures that the GPU can run contemporary titles, but only with reduced visual settings and no ray-traced lighting or reflections.
