AMD Radeon HD 8470D IGP

Power and Cooling — TDP, PSU recommendation, connector requirements

The AMD Radeon HD 8470D IGP is an integrated graphics processor, not a discrete add-in board. Its thermal design power is rated at 65 W, which covers the entire APU package (CPU + GPU) rather than the graphics portion alone. This low power envelope means the IGP draws its power from the motherboard's standard power delivery system, and no dedicated power connectors are required — the field for power connectors is explicitly null, indicating the absence of any supplementary PCIe power inputs.

Because the graphics cores share the system's power infrastructure, there is no suggested PSU rating provided in the data. For an integrated solution of this class, the platform's overall power supply is determined by the CPU and other components, not the GPU. The slot width is listed as "IGP," confirming that this part does not occupy an expansion slot — it is soldered onto the CPU die and uses the motherboard's display outputs, which are described as "Motherboard Dependent." This means the physical integration eliminates any aftermarket cooler or power cabling concerns; the 65 W TDP is the total thermal budget for the entire APU, and cooling solutions designed for 65 W-class processors will suffice.

The 32 nm process node from GlobalFoundries is a mature manufacturing technology, and the die size of 246 mm² houses 1,303 million transistors, yielding a transistor density of 5.3M per mm². This older process node contributes to the modest power draw, but also explains why the performance ceiling is limited compared to later architectures. The production status is "End-of-life," meaning this part is no longer manufactured, but its power characteristics remain relevant for systems still in service.

Ray Tracing and Feature Set — RT/tensor cores, API support from facts

The HD 8470D IGP is built on the TeraScale 3 architecture, which is part of the Richland generation of integrated graphics. This architecture predates dedicated ray tracing hardware — the fact pack lists rtCores as null, and tensorCores as null. Consequently, there is no hardware-accelerated ray tracing support, no dedicated AI tensor cores, and no Vulkan API support (the vulkan field is null). The feature set is firmly rooted in the DirectX 11 era.

API support includes DirectX 11.2 (specifically the 11_0 feature level) and OpenGL 4.4. DirectX 11.2 with the 11_0 feature level indicates that the GPU supports the core DirectX 11 feature set, including tessellation, compute shaders, and multithreaded rendering, but lacks the DirectX 12 and Vulkan capabilities found in modern architectures. OpenGL 4.4 provides compatibility with a wide range of OpenGL applications, though it does not include the newer 4.5 or 4.6 extensions.

The shading units number 192, with 12 texture mapping units (TMUs) and 4 render output units (ROPs). This allocation of resources — a relatively high shader count but very low ROP count — suggests the architecture is optimized for compute-heavy workloads rather than pixel fill rate. The pixel rate is 3.200 GPixel/s, and the texture rate is 9.600 GTexel/s. The FP32 performance is 307.2 GFLOPS. These figures place the IGP firmly in the entry-level segment, with no ray tracing or tensor core capabilities whatsoever. For modern games that require DirectX 12 Ultimate or Vulkan ray tracing, this GPU will be incompatible.

How It Compares — position vs each nearest rival

The fact pack lists no nearest rivals for the AMD Radeon HD 8470D IGP. The nearestRivals array is empty, and the benchmark score is zero. This indicates that the database does not have comparable benchmark data for this particular integrated processor. The percentileVsAllGpus is 50, which suggests that, in the absence of direct rivals, the IGP sits at the median of all GPUs in the database — but this percentile is likely based on limited or imputed data rather than actual comparative benchmarking.

Without rival data, a direct numerical comparison against other GPUs cannot be made. However, the architecture's position in the product stack is clear from its specifications alone. The TeraScale 3 architecture is a predecessor to the GCN 2.0 IGP, which is listed as its successor. The predecessor is TeraScale 2 IGP. This places the HD 8470D IGP as a mid-point in the TeraScale IGP lineage, released on 2013-07-28. The 192 shading units and 4 ROPs are typical of an entry-level integrated solution of that era, designed for basic desktop tasks and light gaming at low resolutions and settings.

The lack of rivals in the database means that any head-to-head comparison must be qualitative. The 50th percentile ranking indicates that it outperforms roughly half of all GPUs ever benchmarked, but this is a broad statement that includes many obsolete and low-end parts. In practical terms, this IGP would be positioned below any discrete GPU from its era, and well below any modern integrated graphics solution. The 65 W TDP, shared with the CPU, means it competes in the same thermal class as other low-power IGPs, but without benchmark data, no specific percentage deltas can be cited.

Benchmark Performance

The benchmark data for the AMD Radeon HD 8470D IGP is notably sparse. The avgBenchmarkScore is 0, and the benchmarks array is empty. This means there are no recorded benchmark scores for this specific IGP in the database. The percentileVsAllGpus is 50, which would place it at the median of all GPUs, but this figure should be interpreted with caution given the absence of actual benchmark data.

Without benchmark scores, performance analysis must rely on the architectural specifications. The FP32 performance of 307.2 GFLOPS is a theoretical peak, not a measured benchmark. The pixel rate of 3.200 GPixel/s and texture rate of 9.600 GTexel/s are derived from the clock speeds and unit counts. The 192 shading units operate at the system's memory clock, which is "System Shared" and therefore dependent on the installed RAM speed. This means actual performance can vary significantly depending on whether the system uses fast DDR3 or slower RAM.

The ROP count of 4 is particularly low, which will bottleneck performance at higher resolutions where pixel fill rate becomes critical. At 1080p, the IGP may struggle to maintain playable frame rates in modern 3D games, especially with anti-aliasing enabled. For older games or esports titles at low settings and 720p, the 307.2 GFLOPS of compute power could be sufficient. The lack of rival data prevents any percentage-based comparisons, but the theoretical numbers suggest this IGP is firmly in the entry-level category, roughly equivalent to the integrated graphics found in low-end laptops and budget desktops from the early 2010s.

Memory Subsystem

The memory subsystem of the HD 8470D IGP is entirely system-dependent. The memory size is "System Shared," meaning there is no dedicated VRAM on the GPU. The memory type is also "System Shared," and the bus width is "System Shared." The bandwidth is listed as "System Dependent." This architecture relies on the system's main memory for all graphics data, which has significant performance implications.

Because the GPU shares the system memory bus with the CPU, the effective bandwidth available to the graphics cores is limited by the system's RAM speed and the memory controller's efficiency. In a typical dual-channel DDR3-1600 configuration, the theoretical maximum bandwidth would be around 25.6 GB/s, but the GPU must contend with CPU memory requests, reducing the effective bandwidth available for graphics workloads. The "System Dependent" designation means that a system with faster RAM will yield better GPU performance, while a system with slower RAM will bottleneck the GPU.

This shared memory design also means that the amount of memory available to the GPU is dynamic, depending on the system's total RAM and the operating system's allocation policy. The lack of dedicated VRAM means that high-resolution textures and large framebuffers will consume system RAM, potentially causing performance degradation if the system has insufficient memory. For the 192 shading units and 4 ROPs, the memory bandwidth is unlikely to be the primary bottleneck in most workloads — the low compute and fill rates will limit performance first. However, at high resolutions with large framebuffers, the shared memory bandwidth could become a secondary constraint.

Who Should Consider It

The AMD Radeon HD 8470D IGP is an integrated graphics solution from the TeraScale 3 era, designed for basic computing tasks rather than demanding gaming. The 307.2 GFLOPS of FP32 performance and 3.200 GPixel/s pixel rate indicate that this IGP is suitable for 720p gaming at low settings in older titles, or for 1080p video playback and desktop productivity. The 50th percentile ranking among all GPUs suggests it outperforms the bottom half of all GPUs ever made, but this is a low bar given that the database includes many ancient and low-end parts.

Gamers considering this IGP should target 720p resolution with low-to-medium settings for games released before 2015. Esports titles like older versions of Counter-Strike or League of Legends could be playable at 1080p if settings are reduced to the minimum. For modern AAA games, the 4 ROPs will severely limit fill rate, and the lack of Vulkan and DirectX 12 support means many current titles will not run at all. Users who primarily need a system for web browsing, office applications, and video streaming will find this IGP more than adequate, as those workloads do not stress the GPU heavily.

The system-dependent memory bandwidth means that users should pair this IGP with dual-channel RAM at the highest speed supported by their motherboard to maximize performance. The 65 W TDP makes it suitable for small-form-factor and low-power builds, but the end-of-life status means it is only available in older used systems. Users requiring modern feature support — ray tracing, Vulkan, DirectX 12 — should look elsewhere, as this IGP lacks all of these capabilities. For retro gaming and legacy applications, the HD 8470D IGP remains a functional, if unremarkable, choice.
