AMD Radeon HD 6630M

The AMD Radeon HD 6630M is a mobile graphics processor built on the TeraScale 2 architecture, utilizing the Whistler chip manufactured on TSMC's 40 nm process. It carries a benchmark score of 327 points in the Geekbench OpenCL test, placing it in a narrow competitive band where its closest rivals are separated by margins of roughly 15 to 20 percent. The data indicates a part that sits in the lower-middle tier of its era, with performance that is respectable for its intended segment but clearly outpaced by stronger desktop parts of the same generation.

Benchmark Performance

The HD 6630M's average benchmark score of 327 points serves as the central reference point for its performance profile. Against its nearest listed rival, the NVIDIA GeForce RTX 2050 Mobile, the AMD part holds a 19.3 percent advantage, scoring 327 versus 274. This is a notable lead, though it must be contextualized by the fact that the RTX 2050 Mobile is a much newer architecture; the delta reflects the specific workload measured in Geekbench OpenCL rather than a general-purpose superiority. Similarly, the HD 6630M outperforms the ATI Radeon HD 5670 by 19.6 percent, with the latter scoring 273 points. That margin is nearly identical to the one over the RTX 2050, suggesting a consistent performance tier for the HD 6630M in this particular test.

The picture flips when comparing to the other two rivals. The ATI Radeon HD 5750 scores 387 points, which is 15.5 percent higher than the HD 6630M's result. The ATI Radeon HD 5450 scores 389 points, a 15.9 percent advantage. These two desktop-oriented parts clearly outclass the mobile HD 6630M in raw compute throughput. The data shows a curious inversion: the HD 6630M beats the HD 5670 by nearly 20 percent but loses to the HD 5750 and HD 5450 by roughly 16 percent. This suggests that the HD 6630M's performance sits in a specific sweet spot relative to those older ATI parts, likely reflecting differences in clock behavior and memory configuration under the Geekbench workload.

In absolute terms, the HD 6630M's 327-point score is modest. Its percentile ranking against all GPUs is 0, indicating that it falls at the very bottom of the distribution in this database—a reflection of its age and mobile-class positioning rather than a commentary on its contemporary relevance. The FP32 compute rate of 480.0 GFLOPS, combined with a pixel rate of 4.000 GPixel/s and a texture rate of 12.00 GTexel/s, provides a structural explanation for the benchmark result. These figures are consistent with a chip designed for 1366x768 or 1600x900 gaming at medium settings in its heyday, though the benchmark data alone does not confirm that usage.

Power and Cooling

Power consumption is a defining characteristic of this mobile part, with a TDP of 26 W. This low figure places it firmly in the realm of thin-and-light laptops or entry-level multimedia notebooks, where thermal headroom is limited. The 40 nm process node from TSMC, housing 716 million transistors on a 118 mm² die, yields a transistor density of 6.1M per square millimeter—a modest figure by modern standards but adequate for the era. The 26 W TDP means that a capable cooling solution, such as a small heatpipe and fan assembly, would suffice; the data does not indicate any need for exotic cooling methods.

The fact pack provides no suggested PSU rating, no power connector requirements, and no slot width details. This is typical for a mobile GPU, where power delivery is handled by the laptop's internal power supply and motherboard rather than a discrete PSU. The bus interface is PCIe 2.0 x16, which draws power from the slot itself, further reducing the need for auxiliary connectors. For a system builder considering this GPU in a desktop context—unlikely given its mobile designation—the 26 W TDP would be trivial to feed. In a laptop, the absence of connector information implies that the GPU is soldered or integrated into the motherboard design, with power managed by the platform's existing VRM circuitry.

The thermal implications of 26 W are straightforward: sustained loads will generate heat that a standard mobile cooling module can dissipate without excessive fan noise. The lack of a boost clock in the fact pack means the GPU operates at a fixed frequency, which simplifies thermal management. The memory clock of 800 MHz, effective 1600 Mbps, contributes to the overall power draw but remains within the 26 W envelope. In practice, the data suggests a part that runs cool enough for slim chassis designs, though the benchmark score of 327 indicates that thermal throttling is unlikely to be a bottleneck for the workloads that this GPU can realistically handle.

Memory Subsystem

The HD 6630M is equipped with 1024 MB of DDR3 memory on a 128-bit bus, yielding a memory bandwidth of 25.60 GB/s. This configuration is modest by any standard, and the bandwidth figure is the single most limiting factor for high-resolution performance. At 25.60 GB/s, the GPU can feed its 480 shading units and 24 texture mapping units adequately for 720p-class workloads, but at higher resolutions, the memory bus will become a bottleneck. The 128-bit interface is a common choice for entry-level parts, balancing cost and die area, but it caps the effective data throughput.

For 1080p gaming, the data implies that texture-heavy scenes would suffer from bandwidth starvation. The 1024 MB frame buffer is sufficient for the resolution's typical texture sizes, but the low bandwidth means that larger textures and higher anisotropic filtering levels will degrade performance disproportionately. The pixel rate of 4.000 GPixel/s further compounds this: at 1920x1080, the GPU would need to fill over 2 million pixels per frame, and at 4.000 GPixel/s, it can theoretically manage around 60 frames per second in pure fill-rate terms—but only if the memory subsystem can keep up, which it cannot at that bandwidth.

Comparatively, the rival ATI Radeon HD 5750, which scores 15.5 percent higher in benchmarks, likely benefits from a wider memory bus, though the fact pack does not specify its memory configuration. The HD 6630M's 25.60 GB/s is a hard ceiling for any workload that requires frequent vertex or texture fetches. In modern terms, this memory subsystem would struggle with even moderate-resolution productivity tasks, but for the era's standard 1366x768 panels, it provides adequate headroom. The 1600 Mbps effective memory speed is standard for DDR3 of that period, and the 128-bit bus is the primary constraint.

How It Compares

Against the NVIDIA GeForce RTX 2050 Mobile, the HD 6630M leads by 19.3 percent in the Geekbench OpenCL score. This is a surprising result given the generational gap, but the data is unambiguous: 327 versus 274. The RTX 2050 Mobile's lower score may reflect driver overhead or workload characteristics that favor the older TeraScale 2 architecture's compute pattern. In a real-world gaming comparison, the RTX 2050 would likely win due to its modern feature set, but the raw compute benchmark shows the HD 6630M holding a clear edge.

The ATI Radeon HD 5670 is the closest competitor in score terms, trailing by 19.6 percent with 273 points. This is a desktop part, and its lower score relative to the mobile HD 6630M is notable. The HD 5670 was a popular entry-level desktop GPU, yet the data shows the HD 6630M outperforming it by a significant margin in this specific test. This could be due to the HD 6630M's higher effective memory clock or architectural refinements in the Whistler chip.

The ATI Radeon HD 5750 is a different story. With 387 points, it beats the HD 6630M by 15.5 percent. This desktop part had a reputation for strong compute performance, and the benchmark confirms that it outclasses the mobile chip. The 15.5 percent delta is substantial, placing the HD 5750 in a clearly higher performance tier.

The ATI Radeon HD 5450, scoring 389 points, is the top rival in this list, beating the HD 6630M by 15.9 percent. This is the most surprising comparison, as the HD 5450 was often considered a lower-tier part than the HD 5670. The data shows otherwise for this workload, with the HD 5450 outperforming both the HD 5670 and the HD 6630M. The 15.9 percent margin over the HD 6630M indicates that the HD 5450's compute capabilities are underrated in its historical context.

Ray Tracing and Feature Set

The HD 6630M has no ray tracing cores and no tensor cores, as these were not part of the TeraScale 2 architecture. The chip relies on its 480 shading units for all compute tasks, with FP32 performance rated at 480.0 GFLOPS. This is a purely traditional rasterization-focused GPU, with no dedicated hardware for ray-traced effects or AI-accelerated workloads. The absence of these features is expected for a 2011-era part, but it means the GPU is entirely unsuitable for modern ray-traced gaming.

API support is limited to DirectX 11.2 (11_0) and OpenGL 4.4. There is no Vulkan support listed in the fact pack, which further restricts its compatibility with modern titles that rely on Vulkan for low-overhead rendering. DirectX 11.2 is a mature API that many older games use effectively, but newer titles that require DirectX 12 or Vulkan will not run on this hardware. The OpenGL 4.4 support is adequate for older productivity applications and legacy games, but it lacks the extensions needed for contemporary OpenGL workloads.

The display outputs are listed as "Portable Device Dependent," meaning the GPU's output capabilities are tied to the laptop's internal display and any external ports provided by the manufacturer. This is standard for mobile GPUs, where the laptop manufacturer decides the physical connectors. The lack of tensor cores also means no DLSS or similar upscaling technology is available, and the absence of RT cores precludes any form of hardware-accelerated ray tracing. For the HD 6630M, the feature set is entirely defined by its rasterization capabilities, and the 26 W TDP ensures that those capabilities are delivered within a power envelope suitable for portable devices.
