AMD Radeon R7 M440 vs Intel Iris Pro Graphics P6300 Comparison

The benchmark data places the Intel Iris Pro Graphics P6300 and the AMD Radeon R7 M440 in adjacent performance tiers, with the Intel part holding a narrow but measurable edge in the single available head-to-head test. The Intel GPU’s average benchmark score of 5712 places it in the 33rd percentile of all GPUs, while the AMD part’s average of 5483 sits just one percentile lower at 32. These are closely matched mobile-class graphics solutions, but their underlying architectural philosophies and specification sheets reveal distinct behavioral profiles.

Where Each One Wins

The Intel Iris Pro Graphics P6300 wins the only direct benchmark comparison available: the Geekbench OpenCL test. In that test, the Intel part scores 5712 against the AMD Radeon R7 M440’s 5214, a decisive 9.6% advantage. This is the sole head-to-head data point, and it belongs entirely to Intel. The AMD Radeon R7 M440, however, counters with a separate benchmark result that the Intel part does not possess: a Geekbench Vulkan score of 5751. While the head-to-head table lists zero wins for AMD, the Vulkan score shows the AMD GPU is capable of competitive performance in a different API environment, exceeding the Intel part’s OpenCL score by 39 points.

Looking at the broader rival landscape, the Intel GPU’s OpenCL score of 5712 places it within 0.1% of the NVIDIA GeForce GTX 670MX (5721) and 0.3% of the NVIDIA GeForce GTX 550 Ti (5731). It also leads the AMD Radeon HD 8790M by 0.4% and the NVIDIA Quadro M500M by 1.9%. The AMD Radeon R7 M440’s average score of 5483, meanwhile, trails the NVIDIA GeForce GTX 765M by 0.3% and the NVIDIA GeForce MX130 by 0.5%, while leading the NVIDIA Quadro M4000 by 0.3% and the AMD Radeon 610M by 0.7%. The data suggests Intel’s part is marginally better positioned against its immediate rivals, while the AMD part’s Vulkan score of 5751 would rank it among the higher performers if compared directly against those same OpenCL results.

The use-case split is therefore clear: the Intel GPU is the stronger choice for OpenCL-based workloads, while the AMD GPU demonstrates a capability in Vulkan that the Intel part cannot claim, based on the available data. The Intel GPU’s pixel rate of 4.800 GPixel/s is lower than the AMD’s 7.128 GPixel/s, but its texture rate of 38.40 GTexel/s more than doubles the AMD’s 17.82 GTexel/s, suggesting the Intel part is better suited for texture-heavy operations while the AMD part excels at raw pixel output.

The Verdict

For users prioritizing OpenCL compute performance, the Intel Iris Pro Graphics P6300 is the clear pick. Its 9.6% lead over the AMD Radeon R7 M440 in the Geekbench OpenCL test is the largest single margin in this comparison, and its average score of 5712 is 4.2% higher than the AMD’s 5483 average. The Intel part also offers a significantly higher texture rate (38.40 GTexel/s vs 17.82 GTexel/s) and more shading units (384 vs 320), which aligns with its OpenCL advantage.

For users who require Vulkan API support, the AMD Radeon R7 M440 is the only option of the two that provides a Vulkan benchmark score. Its 5751 score in Geekbench Vulkan exceeds the Intel part’s OpenCL score of 5712, indicating that in Vulkan-based scenarios, the AMD GPU likely outperforms the Intel GPU’s peak OpenCL capability. The AMD part also supports DirectX 12 (12_0) and OpenGL 4.6, compared to Intel’s DirectX 12 (11_1) and OpenGL 4.4, giving it a more modern API feature set.

The data does not support a universal winner. The Intel GPU wins the OpenCL head-to-head and offers superior texture throughput, while the AMD GPU counters with a higher pixel rate, Vulkan support, and a dedicated 4 GB memory pool. The choice depends entirely on the workload: OpenCL compute favors Intel, while Vulkan rendering and higher pixel throughput favor AMD.

Head-to-Head Benchmarks

The only direct head-to-head benchmark is Geekbench OpenCL, where the Intel Iris Pro Graphics P6300 scores 5712 against the AMD Radeon R7 M440’s 5214. The 9.6% delta is substantial for two GPUs with such similar average scores. This margin is larger than any of the deltas observed in either part’s nearest rival comparisons, indicating that the Intel GPU has a specific advantage in OpenCL workloads that is not reflected in the overall percentile rankings.

The AMD Radeon R7 M440’s Geekbench Vulkan score of 5751 is notable because it exceeds the Intel GPU’s OpenCL score by 39 points. While the head-to-head table does not include a Vulkan comparison, this number suggests that if such a test were run, the AMD part would likely win based on its demonstrated Vulkan performance. The AMD GPU’s fp16 rate of 570.2 GFLOPS (1:1) matches its fp32 rate, whereas the Intel part has no listed fp16 capability, further indicating the AMD part’s strength in modern compute environments.

The Intel GPU’s texture rate of 38.40 GTexel/s is 115% higher than the AMD’s 17.82 GTexel/s, which explains its OpenCL dominance. The AMD GPU’s pixel rate of 7.128 GPixel/s is 48.5% higher than Intel’s 4.800 GPixel/s, showing a clear trade-off between the two architectures. In terms of memory, the AMD part’s 14.40 GB/s bandwidth on a 64-bit bus is specific and measurable, while the Intel part relies on system shared memory with bandwidth described as “System Dependent,” making direct memory performance comparisons impossible.
