The AMD Radeon HD 6470M is an end-of-life mobile graphics solution built on the 40 nm TeraScale 2 architecture, featuring the Seymour chip with 370 million transistors on a 67 mm² die. With a single Geekbench OpenCL score of 731, it sits at the 2nd percentile of all GPUs, indicating that this part is positioned firmly at the entry level of the performance spectrum, even among its contemporaries from the early 2010s.
Memory Subsystem
The Radeon HD 6470M is equipped with 512 MB of DDR3 memory operating at an effective 1600 Mbps, driven across a 64-bit bus interface. This configuration yields a total memory bandwidth of 12.80 GB/s, a figure that directly constrains the GPU's ability to feed its 160 shading units, 8 texture mapping units, and 4 render output units. The narrow 64-bit bus is the primary bottleneck here; even at the modest 2.800 GPixel/s pixel rate and 5.600 GTexel/s texture rate, the memory subsystem is likely to saturate in texture-heavy scenes.
For high-resolution workloads, the data shows this memory configuration is severely limiting. The 512 MB frame buffer is insufficient for modern game assets at 1080p or above, and the 12.80 GB/s bandwidth means that even if the GPU could compute faster, it would stall waiting for data. At 720p or lower, the limited bandwidth becomes less of a liability, but the pixel rate of 2.800 GPixel/s still caps fill-rate-bound scenarios. The 64-bit bus width is half of what many competing entry-level parts used, and the effective 1600 Mbps memory speed does not compensate for the narrow pathway. In practice, this GPU is designed for minimal resolutions and low-detail settings where the 12.80 GB/s pipe can keep up with the 224.0 GFLOPS of FP32 compute.
Who Should Consider It
Benchmark results indicate that the HD 6470M is suitable only for legacy gaming at 720p or below, with reduced detail settings. The 2nd percentile ranking across all GPUs places it below virtually every discrete solution and most integrated graphics from the same era. Users running productivity applications that leverage OpenCL acceleration will find the 731-point score adequate for basic tasks but frustrating for anything compute-intensive.
At 1080p, the combination of 512 MB VRAM and 12.80 GB/s bandwidth will cause texture thrashing and stuttering in any 3D application released after 2011. The GPU is better suited for 2D desktop work, video playback (where the 4 ROPs can handle basic compositing), or very old titles from the DirectX 9 era. The 11.2 (11_0) DirectX support and OpenGL 4.4 API compatibility mean it can run modern API calls, but at performance levels that render them moot. For users with no other option, this card can drive a display and handle light media tasks, but it should not be considered for any form of competitive gaming or creative workload involving 3D rendering.
Benchmark Performance
In the sole recorded benchmark, Geekbench OpenCL, the HD 6470M scores 731 points. This places it 2.7% behind the NVIDIA GeForce GT 415M, which averages 751 points — a marginal gap that suggests near-identical real-world performance in compute tasks. However, the comparison against the NVIDIA Quadro 410 reveals a more substantial deficit: the Quadro 410 scores 804 points, putting the HD 6470M 9.1% behind. This is a meaningful delta for a professional-grade part that is itself entry-level.
The most striking comparison comes from within AMD's own lineup. The Radeon HD 6450, a desktop part, scores 635 points, meaning the HD 6470M is 15.1% faster than its desktop sibling. This inverted relationship is unusual and suggests that the mobile part benefits from a more optimized clock or driver stack in OpenCL workloads, despite sharing the same architectural fundamentals. Finally, against the NVIDIA NVS 310, the HD 6470M trails by 16.9%, with the NVS 310 posting 880 points. That gap represents a significant performance tier separation, particularly for a card intended for multi-display business use rather than graphics-intensive tasks.
The 224.0 GFLOPS FP32 throughput is the theoretical ceiling, but the benchmark score of 731 reflects real-world efficiency losses. The pixel rate of 2.800 GPixel/s and texture rate of 5.600 GTexel/s are consistent with a 40 nm part from 2011, but they lag behind even the low-end rivals listed here in aggregate compute performance. The data shows that the HD 6470M is competitive with the GT 415M, but a clear step below the Quadro 410 and NVS 310.
How It Compares
NVIDIA GeForce GT 415M: The HD 6470M trails this rival by a slim 2.7% margin, with scores of 731 versus 751. In practice, this difference is within run-to-run variance, meaning the two GPUs are effectively interchangeable for gaming and compute. Both are limited by narrow memory buses and low shader counts, making them peers in the entry-level mobile segment.
NVIDIA Quadro 410: A 9.1% deficit against the Quadro 410's 804-point average places the HD 6470M in a lower performance class. The Quadro 410 is a desktop workstation card, and its advantage in OpenCL likely stems from higher sustained clocks or better memory efficiency. For users needing certified drivers or ECC memory, the Quadro is the clear choice, but for raw compute, the HD 6470M is roughly 9% slower.
AMD Radeon HD 6450: The HD 6470M outperforms this desktop sibling by 15.1%, scoring 731 versus 635. This is counterintuitive given the mobile form factor, but the data is unambiguous. The HD 6450 likely suffers from lower memory clocks or a more conservative power envelope, while the HD 6470M's 25 W TDP allows it to maintain higher utilization in burst workloads.
NVIDIA NVS 310: The largest gap in the rival set is against the NVS 310, which leads by 16.9% with 880 points. The NVS 310 is a low-profile business card, yet it still outperforms the HD 6470M by a substantial margin. This indicates that NVIDIA's architecture at this tier was more efficient for compute, and the HD 6470M's TeraScale 2 design struggles to keep pace with even modest Kepler-based competitors.
