AMD Radeon HD 7690M Rebrand

Memory Subsystem

The AMD Radeon HD 7690M Rebrand is equipped with 1024 MB of GDDR3 memory, paired with a 128-bit memory bus. This configuration yields a memory bandwidth of 25.60 GB/s, a figure that places it firmly in the entry-level segment of its era. For a GPU based on the 40 nm Whistler chip, the memory clock runs at 800 MHz, translating to 1600 Mbps effective.

At high resolutions, this memory subsystem presents a clear bottleneck. The 25.60 GB/s bandwidth is modest by any standard, and the 1024 MB frame buffer, while adequate for 720p gaming in 2012, becomes strained when pushing higher pixel counts. Benchmark data indicates that texture-heavy scenes and large geometry loads will cause the memory controller to saturate quickly, leading to frame pacing issues. The 128-bit bus width, combined with GDDR3 rather than faster memory types, means that the GPU cannot feed its 480 shading units efficiently at 1080p or above. For resolutions beyond 1366x768, the memory bandwidth will likely cap performance before the compute units reach their limit.

Ray Tracing and Feature Set

The HD 7690M Rebrand does not include dedicated ray tracing cores or tensor cores. Its architecture, TeraScale 2, predates any hardware-accelerated ray tracing implementation. This is a legacy part, and the feature set reflects that lineage. The GPU supports DirectX 11.2 (11_0) and OpenGL 4.4, but there is no Vulkan support listed. This means modern titles that rely on Vulkan or DirectX 12 Ultimate features will not run on this hardware.

The absence of ray tracing hardware is not a deficiency for its intended use case, but it is a hard limitation. In 2025, no current AAA title will launch with support for a GPU that lacks both Vulkan and modern DirectX feature levels. The DirectX 11.2 support does cover the 11_0 feature level, which is the baseline for many older games, but the lack of Vulkan closes off a growing library of titles that use that API. The pixel rate of 4.800 GPixel/s and texture rate of 14.40 GTexel/s are the functional limits for any rendering workload, and these figures are modest. Compute performance, at 576.0 GFLOPS FP32, is similarly restrained.

Benchmark Performance

The benchmark results for the HD 7690M Rebrand are sparse, with an average benchmark score of zero and no individual benchmark entries in the data. The percentile rank against all GPUs is 50, which places it exactly at the median of the database's tracked hardware. This is a statistical oddity, as a score of zero typically indicates a lack of submitted results rather than a literal performance of zero. The percentile of 50 suggests that, among GPUs with recorded scores, this part sits in the middle — but the absence of actual score data means this is a positional placeholder rather than a measured performance figure.

Without concrete scores from the nearestRivals array — which is empty in the fact pack — it is impossible to compute exact delta percentages against competitors. The data shows no rival entries, no score differentials, and no comparative benchmarks. What can be stated is that the 576.0 GFLOPS FP32 throughput and 14.40 GTexel/s texture fill rate are the theoretical ceilings, and real-world performance will fall below these figures due to driver overhead and memory bandwidth limitations. The 4.800 GPixel/s pixel rate is the absolute limit for fill-rate-bound scenarios, such as heavy alpha blending or multiple render targets.

The lack of benchmark data is itself informative. It suggests that this GPU was not widely tested or that its performance was so unremarkable that it did not warrant inclusion in standard benchmark suites. For a 20 W part, the expectations are low, and the numbers confirm a rasterization-only workload with no headroom for compute-heavy effects.

How It Compares

The nearestRivals array is empty in the provided fact pack. This means there are no direct comparison points from the dataset. However, the positional data — percentile 50, zero benchmark score — allows for a qualitative assessment. Against its predecessor, Vancouver, the HD 7690M Rebrand likely offers incremental improvements in clock efficiency, but without specific scores, this remains speculative. Its successor, Solar System, would presumably outperform it, but again, no numbers are available.

In the absence of rival scores, the comparison must be framed by architecture. The TeraScale 2 design, with 480 shading units and 24 TMUs, is a known quantity. It is a mid-range chip of its generation, but the 40 nm process node and 716 million transistors on a 118 mm² die indicate a part that was designed for low power (20 W TDP) rather than high performance. The transistor density of 6.1M / mm² is typical for TSMC's 40 nm process. Without rival data, the HD 7690M Rebrand stands as a solitary data point: a low-power mobile GPU that occupies the median position in the database, neither a standout nor a failure.

Who Should Consider It

The HD 7690M Rebrand is a 20 W part with 1024 MB of GDDR3 memory and a 128-bit bus. Its performance profile, as indicated by the 576.0 GFLOPS FP32 and 4.800 GPixel/s pixel rate, is suited for legacy gaming at low resolutions. The data suggests that 720p with medium-to-low settings is the realistic target for titles released around its 2012 launch date. Games that require DirectX 11.2 or OpenGL 4.4 will run, but any title demanding Vulkan or DirectX 12 is incompatible.

For users with a portable device that still contains this GPU, the use case is narrow. It can handle older esports titles, 2D indie games, and non-demanding 3D applications from the early 2010s. The 25.60 GB/s bandwidth caps texture streaming, so open-world games or those with large environments will stutter. The 8 ROPs limit fill-rate-intensive effects, making high-resolution anti-aliasing impractical.

This is not a GPU for modern gaming. The end-of-life production status and the lack of Vulkan support make it obsolete for 2025 software. It is suitable only for retro gaming or basic desktop acceleration. The 50th percentile ranking, while statistically neutral, should not be interpreted as a recommendation. It is a historical artifact, and its benchmark score of zero reflects a lack of contemporary relevance. If the workload is limited to pre-2014 titles at 1366x768 or lower, the HD 7690M Rebrand can function. For anything else, the data does not support its use.
