AMD Radeon HD 7660D IGP

Benchmark Performance

The AMD Radeon HD 7660D IGP occupies a peculiar position in the hardware landscape: it is an integrated graphics processor that, according to the data, sits at the 50th percentile among all GPUs ever benchmarked. This median placement is not a statement of capability but rather a reflection of the vast field of weaker and far older parts it outranks, balanced against the substantial number of discrete solutions that leave it behind. With an average benchmark score of zero, the raw quantitative data is effectively null, forcing an analysis based on architectural characteristics and the qualitative reality of its position rather than head-to-head numerical deltas.

The fundamental performance driver here is the TeraScale 3 architecture, built on a 32 nm process at GlobalFoundries. The chip, codenamed Devastator, packs 1,303 million transistors into a 246 mm² die, yielding a transistor density of 5.3 million per square millimeter. The compute configuration is modest by discrete standards: 384 shading units, 24 texture mapping units, and only 8 raster operations pipelines. This yields a pixel fill rate of 6.080 GPixel/s and a texture rate of 18.24 GTexel/s. The FP32 throughput of 583.7 GFLOPS is the single most telling number—it places the IGP in territory where it can handle esports titles and older games at lower settings, but it will buckle under the weight of modern AAA releases. The data suggests a part that is functionally a legacy component, and its end-of-life production status confirms that this is not a forward-looking piece of hardware.

Memory Subsystem

The memory subsystem is where the HD 7660D IGP's integrated nature becomes both its strength and its fatal weakness. The VRAM size, type, and bus width are all listed as "System Shared," meaning the GPU has no dedicated memory of its own. It borrows from the system's main memory pool, and as such, its bandwidth is "System Dependent." This is a critical distinction: performance will scale with the speed and configuration of the host system's RAM, but it will never reach the levels of a dedicated VRAM solution.

For high-resolution gaming, this is a prohibitive limitation. The lack of a fixed bus width means the texture and pixel rates, while fixed at 6.080 GPixel/s and 18.24 GTexel/s, are only achievable if the system memory can feed the GPU fast enough. In practice, the shared memory architecture introduces latency and bandwidth contention with the CPU, which can lead to stuttering and inconsistent frame times in demanding scenarios. The practical advice here is that 1080p is the effective ceiling, and even then, only for undemanding titles. At higher resolutions, the bandwidth bottleneck will be severe enough to make the experience unpleasant, if not unplayable.

Ray Tracing and Feature Set

Ray tracing is entirely absent from this part. There are no dedicated RT cores listed, and the architecture predates any hardware-accelerated ray tracing by nearly a decade. Similarly, tensor cores are nonexistent, meaning no AI-accelerated features like DLSS are available. The feature set is firmly rooted in the DirectX 11 era, with support for DirectX 11.2 (11_0) and OpenGL 4.4. Notably, there is no Vulkan support listed, which cuts off access to a number of modern titles that rely on it for efficient multi-threaded rendering.

What this means in practice is that the HD 7660D IGP is limited to the API landscape of its time. Games that require DirectX 12 or Vulkan will simply not run, or will run with severe compatibility issues. The lack of any form of hardware-accelerated ray tracing means that any game with mandatory RT effects is immediately off the table. This is a part designed for a specific era of gaming, and it does not straddle generational lines. The display outputs are motherboard-dependent, which is expected for an IGP, but it does mean that the quality and type of video outputs available to the user are determined by the motherboard's implementation, not the GPU itself.

Who Should Consider It

Given the data, the HD 7660D IGP is not a component one selects for future-proofing or for playing the latest titles. Its 50th percentile ranking and 583.7 GFLOPS of compute power position it as a solution for legacy gaming and basic desktop acceleration. The realistic use case is for a user building a budget system destined for older games, indie titles, or 2D strategy games, where the 6.080 GPixel/s pixel rate and 18.24 GTexel/s texture rate are sufficient.

At 720p, the part can handle a surprising number of titles from the 2010-2015 era at medium to low settings, provided the system memory is fast enough to avoid bottlenecking the shared memory architecture. At 1080p, the experience becomes more constrained, with users needing to dial settings down to low and accept lower frame rates in anything beyond the most basic esports titles. For any modern AAA game, the data indicates this IGP will not be viable. It is a part for a specific niche: a secondary PC, a retro gaming rig, or a basic office machine that needs light GPU acceleration. The 8 ROPs are a hard limit on fill-rate-heavy effects, and the 24 TMUs will struggle with high-resolution textures.

How It Compares

The data for nearest rivals is empty, which is telling. The HD 7660D IGP has no direct comparisons in the benchmark database, likely because its integrated nature and the era of its release place it in a category that is rarely benchmarked against discrete parts. However, the 50th percentile ranking provides a contextual anchor. It is better than the bottom half of all GPUs, which includes a vast array of ancient integrated solutions and low-end discrete cards from the early 2000s. It is worse than the top half, which encompasses virtually every modern discrete GPU and even many newer integrated solutions.

Without specific rival data, one can only infer its position based on the architecture. As a TeraScale 3 part, it is the successor to TeraScale 2 IGPs and the predecessor to GCN 2.0 IGPs. The gap between this part and its successor is likely significant, as GCN brought substantial improvements in compute efficiency and feature support. The absence of Vulkan support alone puts it at a disadvantage against any GCN-based IGP, which would have access to a broader range of modern APIs. The lack of direct comparison data in the fact pack is a strong signal that this is a part that exists in a vacuum, rarely tested against its contemporaries.

Power and Cooling

The thermal design power is listed at 100 W, which is a remarkably high figure for an integrated graphics processor, reflecting the fact that this is a full chip on a 32 nm process with a substantial transistor count. The slot width is listed as "IGP," meaning it is not a discrete card and takes up no expansion slots. Power connectors are null, and there is no suggested PSU listed. This is because the IGP draws its power from the motherboard's socket, which feeds it through the CPU's power delivery system.

The practical implication of a 100 W TDP for an IGP is that the motherboard's VRM design must be robust enough to handle the load. A standard 400 W power supply is likely sufficient for a system built around this part, provided the rest of the components are modest. The absence of a dedicated power connector means no additional cabling is required, simplifying installation. Cooling is also a non-issue from a card perspective, as the heat is dissipated through the CPU cooler. However, the 100 W figure is a warning that this is not a low-power part, and system builders should ensure adequate case airflow to keep the surrounding components cool. The 32 nm process is old and inefficient by modern standards, so the heat output can be significant under sustained load, even if the performance is not.
