AMD Radeon HD 8750A

Ray Tracing and Feature Set

The AMD Radeon HD 8750A is built on the Graphics Core Next (GCN) 1.0 architecture, using the Mars chip fabricated on TSMC's 28 nm process. This is a significant architectural foundation, as GCN 1.0 introduces asynchronous compute and a unified shader design that differs from older VLIW-based AMD GPUs. The GPU integrates 384 shading units, 24 texture mapping units, and 8 render output units, translating to a pixel rate of 4.800 GPixel/s and a texture rate of 14.40 GTexel/s. Single-precision floating-point performance reaches 460.8 GFLOPS, which is the raw compute throughput available for general-purpose and graphics workloads.

The HD 8750A does not include dedicated ray tracing cores or tensor cores. Its feature set is therefore rooted entirely in rasterization and compute via the GCN 1.0 pipeline. API support includes DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The DirectX 12 support at the 11_1 feature level means the card can run modern DX12 titles, though it lacks the full feature-level 12_0 capabilities found in newer architectures. Vulkan 1.2.170 provides access to contemporary cross-platform graphics APIs, but again, hardware limitations will constrain performance in advanced effects. In terms of display outputs, the card is marked "Portable Device Dependent," meaning the actual connectors are determined by the host device—typically an all-in-one system or laptop—rather than the GPU itself.

How It Compares

The benchmark database places the AMD Radeon HD 8750A at the 50th percentile among all GPUs, which indicates it sits exactly at the median of the performance distribution. However, the nearestRivals field is empty in the data pack, meaning no direct comparative scores from rival products are provided for this entry. Without explicit rival data, positional analysis must rely on the percentile rank and the card's internal specifications.

Given the 50th percentile standing, the HD 8750A outperforms roughly half of the GPUs in the database while trailing the other half. This suggests a mid-tier placement, consistent with its modest hardware configuration: a 64-bit memory bus with DDR3 memory, 1024 MB capacity, and 16.00 GB/s bandwidth. The 8 ROPs and 24 TMUs further reinforce a design aimed at 720p or low-detail 1080p gaming rather than high-end enthusiast workloads. The lack of nearest rival data means no percentage deltas can be cited; the analysis must instead interpret the percentile as a general barometer of its competitive standing.

Who Should Consider It

Benchmark results indicate the HD 8750A is a legacy, end-of-life product suited for specific use cases rather than current-generation gaming. With 1024 MB of DDR3 memory on a 64-bit bus, the card's memory bandwidth of 16.00 GB/s is a limiting factor for texture-heavy scenes and higher resolutions. The 460.8 GFLOPS of FP32 compute and 4.800 GPixel/s pixel rate suggest the card can handle older titles or esports games at 720p with medium to low settings, but it will struggle with modern AAA releases even at 1080p.

The 50th percentile ranking implies that while it is not the weakest GPU in the database, it is also nowhere near the top. For users with an all-in-one system or a portable device that accepts an MXM-A (3.0) module, this card could serve as a modest upgrade over integrated graphics for basic productivity and light gaming. However, the 2 Gbps effective memory speed and 14.40 GTexel/s texture rate will cap performance in any scenario demanding high fill rates. At 1080p, users should expect to reduce settings to low or medium, and even then, frame rates may dip below playable thresholds in demanding scenes. At 720p, the card is more viable, though the 1024 MB frame buffer may cause texture pop-in or reduced texture quality in games that require more video memory.

Power and Cooling

The AMD Radeon HD 8750A carries a thermal design power (TDP) of 45 W. This low power envelope makes it suitable for compact systems where thermal management is a priority. The card is designed as an MXM Module with a slot width of "MXM Module," and it uses the MXM-A (3.0) bus interface. There is no suggested PSU rating provided in the data, and the power connector requirements are not specified, which is typical for MXM modules that draw power from the host motherboard rather than a dedicated PSU connection.

The 45 W TDP means that cooling requirements are modest. A standard heatsink with a small fan, or even a passive cooling solution in a well-ventilated chassis, could manage the thermal output. The 28 nm manufacturing process helps keep power density low, and the 950 million transistors on a 77 mm² die yield a transistor density of 12.3M per mm², which is reasonable for that node. The absence of a suggested PSU figure indicates that the host system's existing power delivery is expected to suffice, as MXM modules typically do not require external power connectors. Users should ensure their system has adequate airflow to remove the 45 W of heat, but no exotic cooling is necessary.

Benchmark Performance

The benchmark data shows an average benchmark score of 0, and the nearestRivals array is empty, meaning there are no direct comparative scores to analyze in terms of percentage deltas. The percentileVsAllGpus field, however, provides a useful anchor: the HD 8750A sits at the 50th percentile, which is a median position. This implies that in a typical benchmark suite, the card performs better than half of the GPUs tested and worse than the other half. Given its specifications, this ranking aligns with expectations for a low-power, entry-level discrete GPU from the 2013 era.

The card's compute capabilities—460.8 GFLOPS FP32—are modest by modern standards, but they represent a baseline for older DirectX 11 titles. The pixel rate of 4.800 GPixel/s and texture rate of 14.40 GTexel/s are the practical limits for resolution and detail settings. At 1080p, a pixel rate of 4.8 GPixel/s means the GPU can theoretically fill 4.8 million pixels per millisecond, which is sufficient for 60 frames per second at 1080p (1920×1080 = 2.07 million pixels) only if other bottlenecks are absent. However, the 16.00 GB/s memory bandwidth will likely become the limiting factor, as texture reads and shader data transfers will saturate this narrow bus.

The 1024 MB memory capacity is another constraint. Modern games often require more than 2 GB of VRAM even at 1080p, so the HD 8750A will either reduce texture quality or suffer from memory swapping. The 64-bit bus width compounds this issue, as it halves the data path compared to 128-bit designs, directly impacting bandwidth. In benchmark terms, the 50th percentile ranking suggests that the card outperforms older integrated graphics and some very low-end discrete GPUs, but it lags behind any mid-range part from the last decade.

The memory clock of 1000 MHz (2 Gbps effective) is slow by modern standards, further limiting performance. The 28 nm process and 950 million transistors are indicative of a small, efficient chip, but efficiency does not translate to high performance. The HD 8750A is best understood as a stopgap solution for systems that require a discrete GPU with low power draw and minimal thermal footprint. Its DirectX 12 (11_1) support ensures API compatibility with modern drivers, but the hardware lacks the shader throughput and memory bandwidth to leverage those APIs for high frame rates.

In summary, the benchmark results place the HD 8750A at the midpoint of the GPU performance spectrum, a position that is consistent with its specifications. The 50th percentile is a clear indicator that this card is neither a high-performance part nor a complete non-starter. It will handle legacy games and light workloads with reasonable competence, but it is not designed for demanding modern applications. The lack of nearestRivals data prevents precise percentage comparisons, but the percentile rank offers a global perspective: it is exactly average, no more, no less.
