ATI Mobility Radeon HD 5830

The ATI Mobility Radeon HD 5830 is an AMD mobile graphics processor built on the TeraScale 2 architecture, using the Broadway chip fabricated by TSMC on a 40 nm process. The die contains 1,040 million transistors across 166 mm², yielding a transistor density of 6.3M per mm². Released on 2010-01-06, the part is now end-of-life, sitting between the M9x predecessor and the Vancouver successor in the product lineage. It connects via a PCIe 2.0 x16 bus interface, and display outputs are portable device dependent, meaning the actual connectors vary by laptop implementation. The part carries 800 shading units, 40 texture mapping units, and 16 raster output units, with a 128-bit GDDR3 memory interface and a 24 W TDP. The only clock figure listed is a memory clock of 800 MHz with a 1600 Mbps effective data rate; base and boost clocks are absent from the specification.

How It Compares

The FACT PACK lists no nearest rivals for this part, so positional analysis rests on the database-wide percentile. The Mobility HD 5830 sits at the 50th percentile across all GPUs, placing it exactly at the median of the database. This is a neutral position: half of all recorded GPUs score higher, half score lower. In the absence of rival entries, the percentile is the only comparative metric available, and it carries the full weight of the positional analysis. The 50th percentile is not a statement of performance strength or weakness; it is a precise midpoint, indicating that the part is statistically average within the tracked GPU population. The PCIe 2.0 x16 interface is the connectivity standard, and it is the only bus option listed for this part.

The predecessor M9x and successor Vancouver bracket this part chronologically, but no performance deltas are recorded between them. The 50th percentile standing suggests a mid-pack mobile part from its era, consistent with the 24 W TDP and 800.0 GFLOPS of FP32 throughput. The transistor density of 6.3M per mm² on a 40 nm process reflects the manufacturing technology of the time, with 1,040 million transistors packed into a 166 mm² die. Without named rivals, the comparison is limited to the database-wide median position, which is the single most informative placement available. The lack of rival data means no deltaPct values can be cited, and the part's standing is defined solely by the percentile against the entire GPU population rather than against direct competitors. This is an unusual situation in the database, but it does not diminish the clarity of the median placement.

Ray Tracing and Feature Set

The Mobility HD 5830 has no dedicated ray tracing cores and no tensor cores; both fields are null in the specification. This is a TeraScale 2 part, which predates hardware-accelerated ray tracing entirely. API support is limited to DirectX 11.2 (11_0) and OpenGL 4.4; no Vulkan support is present. The feature set is therefore anchored to the DirectX 11 era, with no hardware path for ray-traced effects or AI-accelerated workloads. The 800 shading units deliver 800.0 GFLOPS of FP32 compute, which is the primary arithmetic resource for shader work. The 800 shading units are organized in the TeraScale 2 layout, and the 800.0 GFLOPS figure represents the peak FP32 rate. The 40 TMUs produce a texture rate of 20.00 GTexel/s, and the 16 ROPs yield a pixel rate of 8.000 GPixel/s. These figures define the rasterization throughput available to the graphics pipeline, all operating within the 24 W power envelope.

For modern workloads that rely on ray tracing or tensor-based acceleration, the absence of dedicated hardware means such features are entirely unsupported; the part is strictly a rasterization device from the DirectX 11 generation. The DirectX 11.2 (11_0) feature level caps the API capabilities, and OpenGL 4.4 provides the alternative graphics path. The lack of Vulkan support further restricts the part to older API ecosystems. In practical terms, the feature set is defined by what the TeraScale 2 architecture could do in 2010, and nothing more.

Memory Subsystem

The memory subsystem comprises 1024 MB of GDDR3 on a 128-bit bus, running at 800 MHz with 1600 Mbps effective data rate. This yields a bandwidth of 25.60 GB/s. For a mobile part of this generation, that bandwidth is a limiting factor at higher resolutions; the 16 ROPs produce a pixel rate of 8.000 GPixel/s, while the 40 TMUs deliver 20.00 GTexel/s. The 25.60 GB/s figure means texture-heavy scenes at high resolutions will likely encounter bandwidth constraints before compute limits are reached. The 128-bit bus width is narrow by modern standards, but the 24 W TDP suggests the part was designed for power-constrained laptops rather than maximum throughput.

The memory clock of 800 MHz with a 1600 Mbps effective rate is the sole clock figure recorded for this part, as base and boost clocks are not listed. The 1024 MB capacity is modest for the era, and the GDDR3 type, rather than faster memory, further reinforces the bandwidth ceiling. At higher resolutions, the 25.60 GB/s figure would become the primary bottleneck, particularly in scenes with large textures or heavy alpha blending. The relationship between the 8.000 GPixel/s pixel rate and the 25.60 GB/s bandwidth means that, at full pixel throughput, the memory bus would need to supply 8.000 GB of pixel data per second just to sustain fill-rate-bound work, leaving the remaining bandwidth for textures and shader data. The 20.00 GTexel/s texture rate places an even higher demand on the bus, underscoring the bandwidth limitation. The 800 MHz memory clock is the only frequency recorded for the entire card, which limits clock-based analysis to the memory domain alone.

Benchmark Performance

The database records no benchmark scores for this part — the benchmarks array is empty and the average benchmark score is 0. No nearest rivals are listed, so exact percentage deltas cannot be computed. The only positional metric is the 50th percentile across all GPUs, which places the Mobility HD 5830 at the median of the database. This is a meaningful data point: it indicates that, among all GPUs tracked, this part sits precisely in the middle. Without recorded scores, the percentile is derived from the aggregate database rather than from head-to-head tests. The absence of rival entries means no deltaPct values exist to quantify advantages or deficits.

Benchmark results therefore indicate a mid-field position, but the lack of scores prevents finer-grained analysis. The 800.0 GFLOPS FP32 rate and 25.60 GB/s bandwidth are the raw specifications that would inform any such comparison, but no measured outcomes are available to confirm real-world standing. The 50th percentile is the sole quantitative performance indicator, and it places the part at the exact midpoint of the database distribution. The average benchmark score of 0 further confirms that no test results have been aggregated for this GPU, making the percentile the only performance-related statistic on record. The percentile ranking is derived from the full GPU population, and the absence of scores means the ranking cannot be cross-validated against measured results. In the absence of scores, the percentile stands as the definitive comparative statement: median, no more, no less.
