The AMD Radeon HD 8670M is an end-of-life mobile graphics solution built on the GCN 1.0 architecture, using the Sun chip produced on TSMC's 28 nm process. With a Geekbench OpenCL score of 5012, it sits at the 28th percentile of all GPUs, placing it firmly in entry-level territory. The data positions it within a tight cluster of competitors: it is 0.2% ahead of the NVIDIA Quadro 4000, 0.6% ahead of the AMD Radeon R5 M430, and 0.7% ahead of the AMD Radeon R7 M360, while trailing the Intel Iris Pro Graphics 5200 by 0.6%. These margins are negligible, meaning the HD 8670M effectively trades blows with its immediate rivals, offering no decisive advantage in raw compute.
Who Should Consider It
Benchmark results indicate that the HD 8670M is suited for users with modest graphical demands, primarily legacy gaming at low resolutions and reduced detail settings. The 5012 OpenCL score, combined with 7.800 GPixel/s pixel rate and 19.50 GTexel/s texture rate, suggests the card can handle older titles or esports-style games at 720p with conservative settings. At 1080p, the data shows the card will struggle with anything beyond basic 2D workloads or very lightly demanding 3D scenes, as its 14.40 GB/s memory bandwidth becomes a severe constraint for texture streaming and frame buffer operations at higher resolutions.
Users who prioritize portability and battery life over frame rates may find this acceptable, as the architecture is designed for thin-and-light notebooks rather than gaming rigs. The 320 shading units and 8 ROPs are sufficient for productivity tasks like video playback and office applications, but the card is not intended for content creation or modern AAA gaming. Given its 28th percentile standing, it outperforms roughly a quarter of all GPUs in the database, which places it below the median experience expected from even integrated solutions of its era. The HD 8670M is best recommended for users who need discrete graphics for basic acceleration, not for enthusiasts seeking playable frame rates in current titles.
Ray Tracing and Feature Set
The HD 8670M does not include dedicated ray tracing cores or tensor cores, as these features were not part of the GCN 1.0 architecture. Consequently, hardware-accelerated ray tracing is entirely absent from this GPU, and any ray-traced effects in games would fall back to software implementations, which the card's 624.0 GFLOPS FP32 throughput cannot handle acceptably. The feature set relies on traditional rasterization, with the 20 TMUs and 8 ROPs providing the core rendering pipeline.
API support is limited to DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. While the DirectX 12 (11_1) support allows access to some modern API features, it is a feature level that predates many of the advanced rendering techniques used in current games. Vulkan 1.2.170 support is present, which can offer better CPU overhead management in titles that utilize it, but the hardware's raw compute limits will still cap performance. OpenGL 4.6 is available for legacy applications and some emulators. The absence of tensor cores means no DLSS or similar AI-based upscaling, and the lack of RT cores means no hardware-accelerated shadows, reflections, or global illumination.
Memory Subsystem
The memory subsystem is a notable bottleneck. The HD 8670M is equipped with 1024 MB of DDR3 memory on a 64-bit bus, yielding a bandwidth of just 14.40 GB/s. This is exceptionally low by modern standards and directly impacts performance at higher resolutions, where the GPU must fetch and write larger amounts of texture and geometry data. The 64-bit bus width is a primary limiter, as it halves the potential memory throughput compared to a 128-bit interface, even at similar memory clocks.
Memory operates at 900 MHz with 1800 Mbps effective speed, which is typical for DDR3 but far below the speeds of GDDR5 or GDDR6 solutions. For the 1024 MB frame buffer, this means that at 1080p, the card may run out of VRAM in texture-heavy scenes, forcing the driver to use system memory over PCIe 3.0 x8, which further degrades performance. At 720p, the capacity is adequate for most older games, but the bandwidth still restricts the fill rate, as evidenced by the 7.800 GPixel/s pixel rate. The data suggests that users should treat this card strictly as a 720p or lower-resolution solution, as the memory subsystem cannot sustain smooth frame pacing at higher settings.

Benchmark Performance
The Geekbench OpenCL score of 5012 places the HD 8670M in a remarkably tight competitive band. Against the NVIDIA Quadro 4000 (5000), the delta is a mere 0.2%, meaning the two cards are statistically indistinguishable in compute workloads. Similarly, the AMD Radeon R5 M430 (4981) is 0.6% behind, and the AMD Radeon R7 M360 (4978) is 0.7% behind. These differences are within run-to-run variance, so the HD 8670M offers no meaningful performance edge over any of these three rivals. The only competitor it trails is the Intel Iris Pro Graphics 5200 (5042), which leads by 0.6% — again, a negligible margin.
What this data reveals is a saturated entry-level segment where all four GPUs deliver essentially the same OpenCL throughput, hovering around the 5000-point mark. The HD 8670M's 28th percentile standing confirms this is not a standout part; it is one of many similar-performing options. The 624.0 GFLOPS FP32 compute rate is the underlying driver of this score, and it sets a hard ceiling on all compute-heavy applications, including physics simulations, image processing, and any GPU-accelerated encoding.
In practical terms, the benchmark results suggest that users upgrading from the HD 8670M to any of its listed rivals would see no perceptible change in frame rates or application performance. The card's 320 shading units are the same count as found in many competing entry-level parts, and the 20 TMUs do not compensate for the low memory bandwidth. The pixel rate of 7.800 GPixel/s and texture rate of 19.50 GTexel/s are consistent with a GPU that was designed for 28 nm efficiency rather than peak performance. The data strongly indicates that this is a component for basic acceleration, not for anyone measuring performance deltas between generations. It sits exactly where the numbers suggest: at the bottom of the discrete GPU stack, with no single metric that elevates it above the pack.
