About AMD Radeon HD 6330M
The AMD Radeon HD 6330M is a mobile graphics processor from the Vancouver generation of the HD 6300M series, built around the TeraScale 2 architecture. Fabricated by TSMC on a 40 nm process, the chip — codenamed Robson — integrates 292 million transistors across a 59 mm² die, yielding a transistor density of 4.9 million per square millimeter. The part holds the 50th percentile in the benchmark database, a median position among all tracked GPUs, though the database records no individual benchmark scores for it and lists no direct rivals.
How It Compares
The nearestRivals field for the Radeon HD 6330M is empty, meaning the benchmark database does not currently track any competitor comparisons for this part. As a result, no rival names, scores, or percentage deltas are available to anchor a direct head-to-head analysis. What the data does provide is the 50th percentile ranking across all GPUs in the database, which places this chip exactly at the median of the distribution. That percentile is a neutral signal: half of the tracked GPUs sit above it and half below, but without benchmark scores the magnitude of the gap cannot be quantified.
The product lineage is documented through its predecessor and successor designations. The HD 6330M follows the Manhattan chip and precedes the London chip, situating it within a specific generation of AMD's mobile lineup. Its production status is listed as end-of-life, which aligns with its release date of November 25, 2010. The architecture is TeraScale 2, and it supports DirectX 11.2 (feature level 11_0) and OpenGL 4.4, but has no Vulkan support recorded.
Because no rival data exists, the comparison must rest on the chip's own specifications. The 80 shading units, 8 texture mapping units, and 4 ROPs are consistent with an entry-level mobile part of its era. The 64-bit memory bus paired with 1024 MB of GDDR3 yields a bandwidth of 12.80 GB/s, a figure that constrains performance in memory-intensive workloads. The 2.000 GPixel/s pixel fill rate and 4.000 GTexel/s texture fill rate are the primary throughput metrics, and they define the practical ceiling for this GPU's rendering capabilities.
Who Should Consider It
The Radeon HD 6330M is positioned for portable devices — its display output specification is listed as "Portable Device Dependent," confirming a laptop-oriented design. With 80 shading units and an FP32 throughput of 80.00 GFLOPS, the chip is suited to basic desktop composition, video playback, and legacy 2D applications. Users running undemanding workloads at low display resolutions will find the 2.000 GPixel/s pixel rate sufficient for everyday tasks, but the 4.000 GTexel/s texture rate and 12.80 GB/s memory bandwidth place hard limits on texture-heavy 3D content.
The 1024 MB GDDR3 frame buffer is the only memory configuration listed in the data. The 64-bit memory bus is the primary bottleneck; at 12.80 GB/s, the bandwidth is adequate for simple scenes but will throttle performance when textures and geometry exceed the memory subsystem's capacity. The absence of any recorded benchmark scores means the data cannot substantiate specific resolution or quality settings, but the raw throughput figures indicate that high-detail 3D rendering is outside this chip's practical envelope.
This GPU is best suited to users who require basic graphical output from a portable system — productivity applications, web browsing, and media playback. It is not a candidate for modern gaming or GPU-accelerated compute workloads, given the 80.00 GFLOPS FP32 ceiling. The end-of-life production status further suggests that new system integration is unlikely, and the part is relevant primarily to legacy hardware.
Power and Cooling
The Radeon HD 6330M carries a TDP of 7 W, which is exceptionally low for a graphics processor. This figure indicates that the chip consumes minimal power under load, and the specification sheet lists no dedicated power connectors and no suggested PSU rating. The absence of power connector data, combined with the 7 W TDP, implies that the GPU draws its operating power entirely from the PCIe 2.0 x16 bus interface. The data does not specify a slot power limit, but the 7 W figure is the only power-related metric recorded.
Cooling requirements are correspondingly modest. The 7 W TDP means the thermal output is low enough that a small heatsink or passive cooling solution could manage the chip, though the data does not specify any particular cooler design. The lack of a suggested PSU in the specification further reinforces that this is a low-power part, not intended for systems with high-capacity power supplies. The PCIe 2.0 x16 interface is the sole electrical connection, and the display outputs are portable-device dependent, meaning the physical output configuration varies by the laptop chassis.

Benchmark Performance
The benchmark data for the Radeon HD 6330M is sparse: the benchmarks array is empty, and the average benchmark score is recorded as 0. The nearestRivals list is also empty, so no percentage deltas can be computed against competing GPUs. This absence of quantitative comparison data means the performance analysis must rely on the chip's published throughput specifications.
The FP32 compute rate is 80.00 GFLOPS, a figure derived from the 80 shading units operating at the memory clock domain. This is a low compute throughput by any standard, and it places the chip firmly in the entry-level segment. The pixel fill rate of 2.000 GPixel/s and texture fill rate of 4.000 GTexel/s are consistent with the 4 ROPs and 8 TMUs respectively. These rates indicate that the GPU can rasterize simple scenes and apply basic textures, but complex shader workloads will quickly exhaust the available ALU throughput.
The memory subsystem is the most significant constraint. The 64-bit bus width and 12.80 GB/s bandwidth limit the rate at which texture and geometry data can be fed to the shading units. Even if the compute units were fully utilized, the memory bandwidth would bottleneck performance in any scenario that requires streaming large amounts of data. The 1024 MB frame buffer is adequate for low-resolution framebuffers, but the bandwidth is insufficient for high-resolution rendering with multiple render targets.
Without rival scores, the percentile ranking of 50 becomes the only relative metric. A 50th percentile position across all GPUs in the database suggests that the HD 6330M sits at the median of the performance distribution, but the absence of an average benchmark score (recorded as 0) means this percentile is not backed by measured performance data. The interpretation is therefore that the HD 6330M is a median-ranking part in the database's historical catalog, with its actual performance defined by the modest throughput figures above. The DirectX 11.2 and OpenGL 4.4 API support ensure compatibility with a wide range of legacy software, but the 80.00 GFLOPS ceiling and 12.80 GB/s bandwidth will limit it to the lightest graphical workloads.
