AMDAMD Radeon HD 6625M Specifications
Radeon HD 6625M GPU Core
Shader units and compute resources
The AMD Radeon HD 6625M 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 6625M Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the Radeon HD 6625M'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 6625M by AMD dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
AMD's Radeon HD 6625M Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The Radeon HD 6625M'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 6625M
The AMD Radeon HD 6625M is a mobile graphics processor from the Vancouver (HD 6600M) generation, using the Whistler chip on AMD's TeraScale 2 architecture. TSMC manufactures the 716-million-transistor, 118 mm² die on a 40 nm process, resulting in a transistor density of 6.1 million transistors per mm². The GPU contains 480 shading units, 20 TMUs, and 8 ROPs, paired with 1024 MB of DDR3 memory on a 128-bit bus running at 800 MHz (1600 Mbps effective). The memory subsystem provides 25.60 GB/s of bandwidth, while the pixel rate is 3.600 GPixel/s, the texture rate is 9.000 GTexel/s, and single-precision FP32 throughput is 432.0 GFLOPS. It connects through PCIe 2.0 x16, has portable-device-dependent display outputs, supports DirectX 11.2 (11_0) and OpenGL 4.4, and no Vulkan support is listed. The part was released on 2011-01-03 and is end-of-life. The FACT PACK lists no benchmark records and no nearest-rival data, so this assessment is based on the stated hardware configuration.
Who Should Consider It
The specifications describe a low-power discrete mobile GPU for relatively light 3D workloads. The 480 shading units provide enough compute resources for basic shader-heavy effects, and the 432.0 GFLOPS FP32 figure gives a rough measure of the arithmetic throughput available for vertex and pixel processing. However, the 20 TMUs and 8 ROPs limit texturing and fill output; those units feed a 3.600 GPixel/s pixel rate and a 9.000 GTexel/s texture rate. A GPU with eight ROPs is not built for high-resolution, high-detail rendering, and the memory setup reinforces that.
The 1024 MB framebuffer is small, especially when texture sets and geometry buffers compete for the same space. The 128-bit DDR3 interface at 800 MHz produces 25.60 GB/s, which is a narrow data path by later discrete-GPU standards. In practice, this means workloads that repeatedly fetch large textures will hit the memory bandwidth wall before the shading units are fully occupied. Users who want to run less demanding 3D applications, older titles, or workloads that can fit within the 1024 MB capacity and 25.60 GB/s bandwidth may find the HD 6625M sufficient. Scenes with heavy texture detail, large draw calls, or high-resolution framebuffers are outside that envelope.
The 26 W TDP also shapes the intended audience. The GPU is clearly positioned for compact notebooks where battery life and chassis cooling matter more than raw rendering performance. The absence of any benchmark scores in the FACT PACK means there is no measured frame-rate data to refine these recommendations, so the resolution and settings guidance must be inferred from the hardware limits: moderate complexity, restrained texture sizes, and fill rates that respect the 3.600 GPixel/s and 9.000 GTexel/s ceilings.
Ray Tracing and Feature Set
The Whistler chip has no RT cores and no tensor cores. There is therefore no dedicated hardware path for ray-traced effects; any ray tracing workload would have to run on the general-purpose 480 shading units, which are architecturally intended for conventional rasterization. The feature set is tied to TeraScale 2 and the APIs it supports. DirectX 11.2 is listed with feature level 11_0, which defines the DirectX API surface available to applications. OpenGL 4.4 is also supported, giving additional compatibility for cross-platform titles. Vulkan support is not listed, so Vulkan-based applications are not covered by the data sheet.
The 40 nm manufacturing process and 716-million-transistor die size are part of the context for this feature set. The GPU is built around the bus interface PCIe 2.0 x16, which is the system link rather than a display feature. Display outputs are portable-device dependent, meaning the actual ports and capabilities depend on the laptop that implements the GPU, rather than being fixed at the chip level. Because tensor cores are absent, there are no AI-accelerated features in the data sheet; because RT cores are absent, there is no hardware-accelerated ray tracing. This is a rasterization-first part with DX11-era API coverage.
How It Compares
The nearestRivals field in the FACT PACK is empty, so there are no rival names, scores, or deltaPct values to compare against. This prevents any direct percent-lead or percent-deficit statements relative to other GPUs. The only positional data is the percentileVsAllGpus value of 50, which places the HD 6625M at the midpoint of all GPUs in the database. That percentile is, however, paired with an avgBenchmarkScore of 0 and an empty benchmarks array, so the ranking cannot be traced to any tested workload in the FACT PACK.
The predecessor Manhattan and successor London are listed, but the FACT PACK supplies no specifications, scores, or architecture details for either. A generational comparison would require performance figures for those parts, and none are available. The absence of nearest-rival data means the HD 6625M's competitive position cannot be stated beyond the 50th percentile field, which is not corroborated by any benchmark result. In short, the supplied data establishes a neutral list-wide percentile but no concrete rival positioning.
Power and Cooling
The TDP is 26 W, which is a modest thermal budget for a discrete GPU. No suggested PSU is listed, and no power connectors are specified, which aligns with a mobile part whose power is delivered through the host system rather than through external PCIe power cables. The display outputs are portable-device dependent, further indicating that the GPU is designed for integration into laptops rather than standalone expansion cards.
The 40 nm process, 716-million-transistor count, and 118 mm² die size define the physical chip that must be cooled. With a 26 W TDP, the thermal load is low enough that OEM-designed solutions are generally sufficient, but the FACT PACK does not include cooler dimensions, slot width, or a suggested PSU. The PCIe 2.0 x16 bus is the interface between the GPU and the host. Because no power connector requirements are provided, the data sheet leaves power delivery specifics to the platform implementation rather than to an end-user upgrade path.
