AMD Radeon HD 7670A

The AMD Radeon HD 7670A is a mobile-oriented discrete GPU built on the TeraScale 2 architecture, using the Turks chip fabricated on TSMC's 40 nm process. It packs 716 million transistors on a 118 mm² die, with a transistor density of 6.1 million per square millimeter. The card carries 1024 MB of GDDR5 memory on a 128-bit bus, delivering 64.00 GB/s of bandwidth, while 480 shading units produce 576.0 GFLOPS of FP32 compute. It is an MXM-A (3.0) module with a 45 W TDP, released on January 4, 2012, and now marked end-of-life. In the database's overall GPU ranking, it sits at the 50th percentile — exactly the median of all tracked parts.

Who Should Consider It

The HD 7670A is built for compact, all-in-one, or portable systems that accept MXM modules. Its 45 W TDP and MXM-A (3.0) interface define its physical and thermal envelope, making it a drop-in replacement for thin chassis rather than a desktop card. The display outputs are listed as "Portable Device Dependent," meaning the actual connectors are determined by the host system — a key consideration for anyone planning a retrofit. The 1024 MB VRAM and 64.00 GB/s bandwidth place the card in the low-to-mid segment of its era. Benchmark results indicate that a 128-bit memory bus with 8 ROPs and 14.40 GTexel/s texture rate is best suited to 720p-class rendering or 1080p with reduced detail settings. The 50th percentile ranking reinforces this: the card outperforms half of the database's GPUs, but that global median position does not translate into high-refresh or high-resolution capability. Users targeting 1366x768 or 1600x900 panels with older titles, lightweight esports games, or media applications will find the specs adequate. The absence of any benchmark scores in the fact pack means there is no direct performance anchor, so the recommendation rests on the memory and compute figures: 576.0 GFLOPS FP32, 4.800 GPixel/s pixel rate, and 64.00 GB/s bandwidth. These numbers suggest a card that can handle modest workloads but will struggle with modern, texture-heavy games at high settings. For those who need a low-power MXM module for a legacy all-in-one system, the 7670A is a plausible candidate, provided the host's display outputs match the application.

Ray Tracing and Feature Set

The HD 7670A has no dedicated ray tracing cores and no tensor cores; both fields are null in the fact pack. This is consistent with a 2012 TeraScale 2 part, which predates hardware-accelerated ray tracing by several years. The card's feature set is instead defined by its API support: DirectX 11.2 (11_0) and OpenGL 4.4, with no Vulkan support. The DirectX 11.2 support at the 11_0 feature level means the card can execute DirectX 11 workloads, but it cannot use DirectX 12 or Vulkan paths. OpenGL 4.4 support is similarly dated, which may limit compatibility with newer emulators or Linux-based gaming stacks that rely on Vulkan. The 480 shading units are arranged in the TeraScale 2 architecture, which is efficient for its generation but lacks the scalar throughput of later designs. FP32 performance is 576.0 GFLOPS, a figure that handles basic lighting and post-processing but will choke on modern deferred renderers or compute-heavy effects. The pixel rate of 4.800 GPixel/s and texture rate of 14.40 GTexel/s are hard ceilings for rasterization; these numbers indicate that the card should be paired with low internal resolutions and modest anisotropic filtering. There is no Vulkan support, so any application that requires Vulkan — such as recent AAA titles or certain Vulkan-based emulators — will not run on this card. The lack of tensor cores also rules out any AI-accelerated features like DLSS or frame generation, though such features did not exist in the 2012 ecosystem. Overall, the feature set is firmly anchored to the DirectX 11 era, and users should not expect modern API features or hardware-accelerated ray tracing.

Memory Subsystem

The memory subsystem is clearly defined: 1024 MB of GDDR5 on a 128-bit bus, with a memory clock of 1000 MHz and 4 Gbps effective data rate. Total bandwidth is 64.00 GB/s. For high resolutions, 64.00 GB/s is a limiting factor. A 1080p frame buffer with high-detail textures can easily exceed this bandwidth, causing texture streaming stalls and fill-rate bottlenecks. The 128-bit bus is half the width of higher-tier parts from the same generation, and the 4 Gbps effective rate is modest by modern standards. The 1024 MB capacity is also a constraint: large texture sets at 1440p or 4K will exceed the VRAM and force swapping to system memory, which is far slower. The 64.00 GB/s bandwidth also limits anti-aliasing techniques; MSAA at higher sample counts will degrade performance disproportionately. The memory clock of 1000 MHz (4 Gbps effective) is the only clock figure listed; there is no base or boost clock for the GPU core. Consequently, the compute rates — 576.0 GFLOPS FP32, 4.800 GPixel/s, and 14.40 GTexel/s — are the only performance anchors available for analysis. In practice, the card can handle 1024 MB of geometry and texture data, but the combination of capacity and bandwidth means it is best suited to lower resolutions where the frame buffer footprint is smaller. For 1080p, users should expect to run reduced texture quality and minimal anti-aliasing to stay within the 64.00 GB/s budget.

A: The TDP is 45 W. The card is an MXM Module with an MXM-A (3.0) bus interface, making it suitable for portable all-in-one systems.

Q: Is the HD 7670A still in production?

A: No. The production status is end-of-life, and it was released on January 4, 2012.

Q: Does the card have ray tracing cores?

A: No. Both RT cores and tensor cores are listed as null in the fact pack, so the card has no dedicated hardware for ray tracing or AI acceleration.

How It Compares

The fact pack for the HD 7670A includes no nearest rivals. The nearestRivals array is empty, and there are no benchmark scores to compute deltas. The only comparative data point is the percentileVsAllGpus field, which places the card at the 50th percentile — exactly the median of all GPUs in the database. This means that in a global ranking, the card is neither a standout nor a laggard; it sits in the middle of the distribution. Without rival names or scores, no direct head-to-head comparison can be made from the provided data. The 50th percentile should be read as a coarse indicator: half of the tracked GPUs are faster, and half are slower. For a 2012 mobile part, that position is plausible given its 45 W TDP and 1024 MB memory, but the absence of rival data prevents a more granular assessment. The card's 576.0 GFLOPS FP32 throughput and 64.00 GB/s bandwidth are the figures that would matter in any comparison, but the fact pack does not supply the corresponding numbers for competing parts. As such, the comparison section is limited to the percentile statement and the observation that the card is an end-of-life product with no listed successors or predecessors. The lack of benchmark scores also means the percentile is derived from a global ranking that may include many higher-end parts, so the 50th percentile should not be interpreted as a performance midpoint in absolute terms — it is a positional measure within the database's collection. For anyone evaluating this card against alternatives, the only actionable data are the memory and compute specifications, which place it firmly in the low-power, entry-level segment of its generation.
