Shader units and compute resources
The AMD Radeon HD 6430M GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.
HD 6430M Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the Radeon HD 6430M's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The Radeon HD 6430M by AMD dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
AMD's Radeon HD 6430M Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The Radeon HD 6430M's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.

About AMD Radeon HD 6430M
The AMD Radeon HD 6430M is a mobile GPU entry from the Vancouver generation, labeled as HD 6400M by the database. The chip is named Seymour and is built on the TeraScale 2 architecture. Manufacturing details show TSMC's 40 nm process, with 370 million transistors in a 67 mm² die, for a transistor density of 5.5M per mm². Memory is 1024 MB of DDR3 on a 64-bit bus; the memory clock is 800 MHz with 1600 Mbps effective transfer, yielding 12.80 GB/s of bandwidth. The compute pipeline is built from 160 shading units, 8 texture mapping units, and 4 render output units. Pixel throughput is 1.920 GPixel/s, texture throughput is 3.840 GTexel/s, and FP32 compute is 153.6 GFLOPS. The database records a release date of 2011-01-03 and a production status of End-of-life. The predecessor is Manhattan and the successor is London. The average benchmark score is 0, the percentileVsAllGpus is 50, and the nearestRivals array is empty.
Who Should Consider It
Benchmark results are not recorded for the HD 6430M: the benchmarks array is empty and the average benchmark score is 0. That means no measured frame-rate evidence exists in the database to anchor a resolution or settings recommendation. The percentileVsAllGpus figure of 50 places this GPU at the midpoint of the database's GPU population, but the zero average score makes clear that the percentile is not accompanied by a concrete performance baseline. The specification sheet has to stand in for measured data. Memory bandwidth of 12.80 GB/s over a 64-bit DDR3 bus is a narrow path; 1024 MB of memory can hold assets, but high-resolution texture sets will strain that capacity. The pixel rate of 1.920 GPixel/s and texture rate of 3.840 GTexel/s set a firm limit for fill-rate-heavy effects, while 153.6 GFLOPS of FP32 throughput from 160 shading units is a modest shader budget. This combination points toward undemanding 2D desktop composition, legacy titles, and older 3D applications with reduced settings. It does not point toward high-detail 1080p gaming or shader-heavy scenes. The database lists no display outputs, so the maximum supported display configuration is not specified, and the only installation interface given is PCIe 2.0 x16. Users whose workloads fit within those constraints are the target audience for this part; users seeking high-refresh or high-resolution 3D rendering are not supported by the data.
Ray Tracing and Feature Set
Ray tracing resources are entirely absent from the specification. The rtCores field is null and the tensorCores field is null, meaning the database records no dedicated ray tracing or tensor hardware. The architecture is TeraScale 2, and no RT or tensor capability appears under that label in the record. API support is limited to DirectX 11.2 (11_0) and OpenGL 4.4; Vulkan support is not listed, so a Vulkan-only workload falls outside the stated feature envelope. Within those APIs, the feature set is carried by the conventional fixed-function and shader blocks already described: 160 shading units, 8 TMUs, and 4 ROPs. The clock specification is incomplete; the only clock value recorded is the memory clock of 800 MHz, with an effective data rate of 1600 Mbps. There is no base clock or boost clock in the FACT PACK, so the relationship between memory timing and shader execution cannot be reconstructed from the database. The two quantifiable performance anchors are the FP32 rate of 153.6 GFLOPS and the memory bandwidth of 12.80 GB/s, which together define the practical feature ceiling of this TeraScale 2 part.
How It Compares
The nearestRivals array is empty, so the database provides no direct competitor entries, no rival scores, and no deltaPct values for the HD 6430M. Because there are no named rivals, no rival-by-rival comparison paragraphs can be constructed from the FACT PACK. The only aggregate positional data is the percentileVsAllGpus field, which is 50; interpreted literally, that places the GPU at the median of the database's GPU population, with half of the population above and half below. The average benchmark score of 0 offers no additional comparison granularity beyond that percentile. The database does identify a product lineage: Manhattan is listed as the predecessor and London as the successor. However, the entry contains no performance scores for either of those GPUs, so the generational relationship is defined by name only, not by measured deltas. The underlying specifications — 1024 MB of DDR3 on a 64-bit bus, 153.6 GFLOPS of FP32 compute, 12.80 GB/s of bandwidth, and a 1.920 GPixel/s pixel rate — describe a part that is numerically modest by modern database standards, but a measured comparison against a specific rival cannot be made from this record.
Power and Cooling
The power and cooling fields in this database entry are largely null. The TDP field is null, the suggested PSU field is null, and the power connectors field is null, so the record contains no thermal design power figure, no power supply recommendation, and no connector count. Slot width is also null, meaning physical clearance and expansion-slot footprint cannot be assessed from the data. What the entry does offer is structural context. The chip is manufactured on TSMC's 40 nm process, contains 370 million transistors, and measures 67 mm², with a transistor density of 5.5M per mm². The electrical side is partially specified by the memory configuration: DDR3 on a 64-bit bus, an 800 MHz memory clock, 1600 Mbps effective data rate, and 12.80 GB/s of bandwidth. The bus interface is PCIe 2.0 x16, which is the only board-level connectivity detail given. No cooler, fan, or heatsink specification is present anywhere in the FACT PACK. Without a TDP value, any power-supply sizing suggestion would require data that is not in the record, so the database cannot support a wattage recommendation. The only safe conclusion is that power behavior is not quantified in this entry.
