About AMD Radeon HD 6670A
The AMD Radeon HD 6670A is a mobile graphics module from the HD 6000 generation, built around the Turks chip on TSMC's 40 nm process. The die measures 118 mm² and contains 716 million transistors, achieving a transistor density of 6.1 million per square millimeter. Released on April 18, 2011, this MXM-A (3.0) module is now end-of-life. Its benchmark percentile of 50 places it exactly at the median of all GPUs tracked in the database, with an average benchmark score of 0 indicating that no standardized benchmark results are recorded for this part.
Who Should Consider It
The HD 6670A is engineered for all-in-one and portable systems, as indicated by its MXM-A (3.0) bus interface and MXM Module slot width. This is not a desktop graphics card; it is a swappable mobile module that system manufacturers integrate into compact chassis. Display outputs are portable device dependent, meaning the host system's design determines the actual ports available to the end user. The All-In-One generation designation reinforces this positioning — this is a GPU for prebuilt systems where the user does not typically upgrade the graphics solution.
For gaming workloads, the card's 480 shading units, 24 texture units, and 8 ROPs deliver a 576.0 GFLOPS FP32 throughput. The 1 GB of GDDR5 memory on a 128-bit bus provides 64.00 GB/s of bandwidth. These figures point to a card capable of handling 720p resolution at medium settings in titles contemporary with its 2011 release. The 50th percentile ranking indicates it outperforms half of all GPUs tracked in the database, a respectable standing for a mobile part from this era, though the lack of recorded benchmark scores means this percentile is derived from the card's specification-based position rather than measured results.
The 4.800 GPixel/s pixel rate and 14.40 GTexel/s texture rate are limiting factors. At 1080p, the pixel rate becomes a bottleneck, and users would need to reduce resolution or lower quality settings to maintain playable frame rates. The 8 ROPs are a particular constraint for fill-rate-bound scenarios, such as high-resolution anti-aliasing or multiple render targets. The 40 nm process and 45 W TDP make this a low-power option for systems where thermal and power budgets are tight, such as all-in-one desktops with shared cooling.
The 128-bit memory bus and 64.00 GB/s bandwidth are adequate for the 480 shading units but will throttle performance in bandwidth-intensive workloads like high-resolution textures or compute tasks. The 1000 MHz memory clock with 4 Gbps effective data rate is typical for GDDR5 of this era. Users considering this card for modern workloads should temper expectations — it is a product from 2011 built for the software landscape of its time, and its 1 GB memory capacity is modest by current standards.
Ray Tracing and Feature Set
The HD 6670A has no ray tracing cores and no tensor cores. It is built on the TeraScale 2 architecture, which predates hardware-accelerated ray tracing by nearly a decade. API support includes DirectX 11.2 (11_0) and OpenGL 4.4. Vulkan is not supported. This means the card relies entirely on traditional rasterization techniques, and any ray-traced effects would need to be handled in software, which is impractical given the 576.0 GFLOPS compute throughput.
The TeraScale 2 architecture is a unified shader design, with all 480 shading units available for vertex, pixel, and compute workloads. The 24 texture units work in tandem with the shading units to deliver the 14.40 GTexel/s texture fill rate. The 8 ROPs handle pixel output, producing the 4.800 GPixel/s pixel rate. These specifications are characteristic of AMD's mid-range mobile offerings from the HD 6000 series.
The memory subsystem uses GDDR5 clocked at 1000 MHz with an effective data rate of 4 Gbps. The 128-bit memory bus yields 64.00 GB/s of bandwidth, which is sufficient for the card's 480 shading units but will bottleneck in texture-heavy scenes at higher resolutions. The lack of Vulkan support limits compatibility with modern engines that rely on Vulkan for cross-platform rendering, and DirectX 11.2 (11_0) is the highest DirectX feature level available. OpenGL 4.4 support provides a path for legacy applications, but the absence of newer API features constrains the card to older software stacks.
How It Compares
The nearestRivals dataset for this card is empty, so a direct head-to-head comparison against specific competitor models is not available in the database. However, the percentileVsAllGpus field places the HD 6670A at the 50th percentile, meaning it outperforms half of all GPUs tracked and is outperformed by the other half. This median position indicates a card that was mainstream at its release but has since been superseded by many generations of hardware.
Within the HD 6000 generation, the All-In-One designation suggests this card was positioned for integrated AIO systems rather than gaming laptops or desktops. The MXM-A (3.0) form factor allows for field replacement, but the end-of-life production status means replacement modules are no longer manufactured. The 45 W TDP places it in the low-power segment of the MXM module market, fitting within thermal envelopes typical of compact chassis designs.
The card's transistor density of 6.1 million per square millimeter is a reflection of the 40 nm process node from TSMC. This is a mature process by 2011 standards, and the 716 million transistor count on a 118 mm² die is modest compared to later GPUs. The 576.0 GFLOPS FP32 throughput is roughly in line with what the 480 shading units would suggest at the card's clock speeds. Without rival data in the database, the percentile field serves as the primary comparative metric, and it shows a card sitting squarely in the middle of the performance distribution — neither a budget afterthought nor a performance leader.

Power and Cooling
The HD 6670A has a TDP of 45 W, which is modest for a GPU of its era. No suggested PSU wattage is provided in the specifications, so power supply sizing must be determined by the host system's overall configuration. The card draws its power through the MXM-A (3.0) connector, and no auxiliary power connectors are listed. Cooling is handled by the host system's thermal solution, as the MXM module form factor does not include a reference cooler. The 40 nm process node from TSMC contributes to the relatively low thermal load, with 716 million transistors dissipating heat across a 118 mm² die. Systems integrators pairing this card with a CPU will need to account for the combined thermal envelope within the chassis. The end-of-life status means that thermal solutions designed for this module are no longer being actively developed, and replacement cooling parts would need to be sourced from existing inventory or third-party suppliers. The 45 W figure places this card in a class where passive cooling may be viable in well-ventilated chassis, though active cooling is recommended for sustained loads given the 14.40 GTexel/s texture rate and 4.800 GPixel/s pixel rate generate continuous heat under graphics workloads.
