AMD Radeon HD 6830M

The AMD Radeon HD 6830M is a mobile graphics processor built on the TeraScale 2 architecture and manufactured on TSMC's 40 nm process. It integrates 1,040 million transistors into a 166 mm² die, yielding a transistor density of 6.3M per mm². Released on January 3, 2011, as part of the Vancouver generation (HD 6800M), it is now end-of-life. The GPU contains 800 shading units, 40 texture mapping units, and 16 raster output units, delivering a peak FP32 performance of 920.0 GFLOPS. Its performance percentile relative to all GPUs in the database is 50, placing it exactly at the median of the distribution.

Memory Subsystem

The HD 6830M ships with 1024 MB of DDR3 memory on a 128-bit bus. The memory clock runs at 800 MHz, which translates to an effective data rate of 1600 Mbps. This configuration produces a memory bandwidth of 25.60 GB/s. For a mobile GPU of its era, this is a modest figure. The 128-bit interface limits the amount of data that can be transferred per clock cycle, and the 25.60 GB/s bandwidth becomes a bottleneck at higher resolutions. At 1080p, the 1 GB VRAM capacity may restrict texture detail in modern titles, though for games released around 2011 it was adequate. At 1440p or above, the bandwidth and capacity would be severely stressed, causing frame drops and texture pop-in. Users should plan for 720p gaming or lower settings at 1080p. The memory clock of 800 MHz is typical for DDR3 of that period, and the effective 1600 Mbps rate is consistent with the architecture's expectations.

Ray Tracing and Feature Set

The HD 6830M does not include dedicated ray tracing or tensor cores. Its TeraScale 2 architecture predates hardware-accelerated ray tracing, so any ray-traced effect would rely on compute shaders, which lack the efficiency of dedicated hardware. The GPU supports DirectX 11.2 (feature level 11_0) and OpenGL 4.4, but no Vulkan support is listed. This means the card cannot run modern ray-traced games or applications that require Vulkan. The feature set is limited to the rasterization pipeline of its time, which is sufficient for traditional rendering but not for contemporary effects. The 800 shading units and 40 TMUs provide a baseline of compute throughput that aligns with its 50th percentile standing. For users interested in ray tracing or advanced lighting, this GPU is not a viable option. However, for older DirectX 11 titles and OpenGL applications, it can deliver acceptable performance within its memory constraints.

Power and Cooling

The HD 6830M has a thermal design power of 39 W. This is a relatively low TDP for a discrete mobile GPU, allowing for thinner and lighter laptop designs. The fact pack does not list a suggested PSU rating or power connector requirements, which is typical for mobile parts that draw power from the motherboard. Display outputs are described as "Portable Device Dependent," meaning the connectors vary by laptop implementation. Cooling is likewise dependent on the chassis; the low TDP suggests that a modest heat pipe and fan arrangement would suffice. No slot width is given, as this is an integrated-on-board solution rather than a removable card. The 40 nm process helps keep power consumption in check, contributing to the 39 W figure. The lack of a separate power connector implies that the GPU is powered entirely through the PCIe 2.0 x16 interface, which is standard for low-power mobile parts.

How It Compares

Without direct rival data in the benchmark database, the HD 6830M's position can be inferred from its 50th percentile rank among all GPUs. This places it exactly at the median of the performance distribution, meaning half of all GPUs are faster and half are slower. Its predecessor, the Manhattan, and successor, the London, are listed but no scores are provided, so a quantitative comparison is impossible. The 50th percentile suggests that for its generation, the HD 6830M was a mainstream solution, not a high-end part. It would have been outperformed by higher-tier mobile GPUs of the same era, but it also outclassed integrated graphics. The lack of nearest rivals in the data means we cannot name specific competitors, but the percentile alone indicates a mid-range positioning. The GPU's 920.0 GFLOPS of FP32 compute and 25.60 GB/s memory bandwidth are consistent with a median performer. In a field where many GPUs exceed 1000 GFLOPS, the HD 6830M sits comfortably in the middle.

Who Should Consider It

Given its 1 GB DDR3 memory, 128-bit bus, and 25.60 GB/s bandwidth, the HD 6830M is best suited for 720p gaming at medium to low settings, or for 1080p playback of video content. Its 920.0 GFLOPS of FP32 compute is adequate for older titles and esports games that are not graphically demanding. The 50th percentile rank reinforces that it delivers average performance for the database. Users who require high refresh rates at 1080p or any form of ray tracing should look elsewhere. Because the GPU is end-of-life and was released in early 2011, it is not a candidate for new purchases. However, for a legacy laptop that already has this GPU, it can handle casual gaming and productivity tasks. The 39 W TDP makes it efficient for battery life, but the overall performance is limited by the memory subsystem and lack of modern features. In summary, the HD 6830M is a capable entry-level mobile GPU for its time, but it is not suited for modern high-resolution or ray-traced workloads. Its 50th percentile standing confirms that it is neither a standout nor a laggard, but a dependable middle-of-the-road component for laptops from its era.
