AMD Radeon HD 7750

The AMD Radeon HD 7750 is a 28 nm GCN 1.0 part from the Southern Islands generation, built around the Cape Verde chip with 1,500 million transistors on a 123 mm² die. It launched on February 14, 2012 with a launch MSRP of 109 USD, and is now end-of-life. With an average benchmark score of 430 and a 1st percentile standing among all GPUs, it sits at the very bottom of the performance hierarchy—yet its small footprint, single-slot design, and 55 W TDP make it a curious artifact for legacy systems and low-load use cases.

Who Should Consider It

The HD 7750’s benchmark results paint a clear picture of its intended audience. Its Passmark G3D score of 1703 places it far below any modern discrete GPU, and the DirectX 11 score of 10 suggests that even light 3D workloads will struggle. However, the DirectX 9 score of 33 is comparatively stronger, and the G2D score of 442 indicates competent 2D acceleration. This card is best suited for systems that only need basic display output, legacy software that relies on DirectX 9 or earlier, or as a low-cost fallback for troubleshooting. At 1024 MB of GDDR5 memory with 72.00 GB/s of bandwidth, it can handle low-resolution textures and simple scenes, but high-resolution gaming is out of the question. For anyone considering it today, the data implies a machine dedicated to office productivity, media playback, or very old titles—not a modern gaming rig.

Ray Tracing and Feature Set

The HD 7750 has no dedicated ray tracing cores and no tensor cores, as those are absent from the FACT PACK. Its feature set is instead defined by API support: DirectX 12 (at feature level 11_1), OpenGL 4.6, and Vulkan 1.2.170. This means the card can run applications written for these modern APIs, but it will do so with the hardware limitations of a 2012 architecture. The lack of RT and tensor hardware makes it unsuitable for any ray-traced effects or AI-accelerated workloads. The presence of DisplayPort 1.2 and HDMI 1.4a outputs allows for standard monitor connectivity, but there is no support for high refresh rates or advanced display features beyond what those older standards provide.

How It Compares

Against the Intel HD Graphics 4000, the HD 7750 holds a 4% advantage in average score (430 vs. 414). This is a narrow margin, meaning the two are nearly interchangeable for light 2D and basic 3D tasks, though the discrete card’s dedicated memory gives it a slight edge in texture-heavy scenarios.

The AMD Radeon HD 6850 is 6.2% ahead of the HD 7750, with an average score of 459. That gap is modest, but the 6850’s higher memory bandwidth and greater compute resources make it the better choice for any game that pushes beyond minimal settings. The HD 7750 trails by a small but consistent margin.

Relative to the ATI Radeon HD 5450, the HD 7750 is 10.5% faster (430 vs. 389). This is a clear step up, but both cards occupy the same performance stratum—neither is capable of modern 3D rendering. The HD 7750’s advantage is more pronounced in compute-oriented tasks, as shown by its GPU Compute score of 808 versus the 5450’s lower output.

The ATI Radeon HD 5750 is 11.1% ahead of the HD 7750 (430 vs. 387). That is the largest delta among the nearest rivals, yet the absolute difference remains small. The HD 7750 is the slower card, but the two are close enough that any real-world difference would be imperceptible outside of synthetic benchmarks.

FAQ

Q: Does the HD 7750 support DirectX 12?

A: Yes, it supports DirectX 12, but only at feature level 11_1, meaning it cannot use the full DirectX 12 feature set.

Q: Does the card have ray tracing capabilities?

A: No. The FACT PACK lists no RT cores, so hardware-accelerated ray tracing is not available.

Q: What is the memory configuration?

A: It has 1024 MB of GDDR5 on a 128-bit bus, providing 72.00 GB/s of bandwidth.

Q: What power supply is recommended?

A: AMD suggests a 250 W PSU. The card itself has a 55 W TDP and requires no power connectors.

Q: What display outputs are available?

A: It offers one DVI, one HDMI 1.4a, and one DisplayPort 1.2 output.

Q: Is the card still in production?

A: No, it is end-of-life, having been succeeded by the Sea Islands generation.

Power and Cooling

The HD 7750 is remarkably power-efficient for its era, with a TDP of just 55 W. It draws all its power from the PCIe slot, as it has no auxiliary power connectors. AMD recommends a 250 W power supply, which is modest by any standard. The card is single-slot, measuring 168 mm (6.6 inches) in length, making it suitable for compact cases. Its low power draw and lack of connectors mean it can be dropped into nearly any system without worrying about PSU capacity or cable management. The cooling solution is not specified, but the low TDP suggests a simple passive or low-profile fan would suffice.

Memory Subsystem

The HD 7750 pairs 1024 MB of GDDR5 with a 128-bit memory bus, yielding a bandwidth of 72.00 GB/s. The memory clock is 1125 MHz, translating to 4.5 Gbps effective. This configuration is typical for a low-end card of its generation. At 1080p and above, the 1 GB capacity becomes a limiting factor, as modern textures easily exceed this amount. The bandwidth, while adequate for 2D and light 3D, will throttle performance in any scene that demands frequent texture swaps. For high resolutions, the memory subsystem is a bottleneck; the card’s 12.80 GPixel/s pixel rate and 25.60 GTexel/s texture rate are simply too low to feed a large frame buffer. The data suggests that this card is best used at 720p or lower, with reduced texture quality.

Benchmark Performance

The HD 7750’s synthetic scores are consistently low, but they reveal its relative strengths and weaknesses. The Passmark G3D score of 1703 is the headline number, yet it is dwarfed by the nearest rivals: the HD 6850 scores 459 in average benchmark (6.2% higher), while the HD 5750 scores 387 (11.1% higher). The card does manage to outperform the Intel HD 4000 by 4% and the ATI HD 5450 by 10.5%, but those are not meaningful victories—they are all in the same performance basement. The DirectX 9 score of 33 is the highest among the API tests, indicating that the architecture is better optimized for older shader models. The DirectX 10 score of 7 and DirectX 11 score of 10 are abysmal, and the DirectX 12 score of 8 confirms that the card cannot handle modern graphics workloads. The GPU Compute score of 808 is also weak, reflecting the limited FP32 throughput of 819.2 GFLOPS. The pixel rate of 12.80 GPixel/s and texture rate of 25.60 GTexel/s are similarly modest. In summary, the HD 7750 is a card that was entry-level in 2012 and is now obsolete for any serious 3D work. Its only saving grace is its low power draw and small footprint, which make it a curiosity for retro builds or as a diagnostic tool. The benchmark data leaves no doubt: this is a card for display output, not performance.
