AMD Radeon R5 M430 vs Intel Iris Pro Graphics P6300 Comparison

The Verdict

The Intel Iris Pro Graphics P6300 is the faster part in the only recorded head-to-head benchmark, Geekbench OpenCL. Its score of 5712 beats the AMD Radeon R5 M430's 5152 by 10.9%. The Intel part also holds a percentile advantage, sitting at the 33rd percentile of all GPUs compared to the AMD's 30th. For raw compute workloads that rely on OpenCL, the Intel solution is the clear pick.

The AMD Radeon R5 M430 does have its own advantages. It carries 4 GB of dedicated DDR3 memory on a 64-bit bus, while the Intel part is entirely system shared. The AMD also supports a higher OpenGL version (4.6 vs 4.4) and a newer Vulkan version (1.2.170 vs 1.0). If you need a discrete frame buffer or modern API support for specific applications, the AMD part is the one to choose. However, the data shows that in pure OpenCL compute, the Intel chip is ahead.

For an older laptop or a system where the Intel IGP is the only option, the P6300 is a capable performer for its class. For a portable device that needs a dedicated memory pool and up-to-date graphics API compliance, the R5 M430 is the practical pick. Neither part is a gaming powerhouse; both are end-of-life mobile graphics solutions.

Architecture Differences

The Intel Iris Pro Graphics P6300 is built on Broadwell GT3e silicon, using Intel's Generation 8.0 architecture on a 14 nm process. The AMD Radeon R5 M430 uses the Jet chip with GCN 1.0 architecture on a 28 nm process from TSMC. The process node difference is significant: 14 nm versus 28 nm, which gives Intel a density and efficiency edge on paper.

Intel integrates 384 shading units, 48 texture mapping units, and 6 ROPs. AMD counters with 320 shading units, 20 TMUs, and 8 ROPs. The Intel part has more shaders and far more TMUs, while AMD has slightly more ROPs. Pixel rate favors AMD at 6.840 GPixel/s versus Intel's 4.800 GPixel/s. Texture rate is a landslide for Intel: 38.40 GTexel/s versus 17.10 GTexel/s. FP32 compute also favors Intel at 614.4 GFLOPS against AMD's 547.2 GFLOPS.

The AMD chip contains 690 million transistors on a 56 mm² die with a transistor density of 12.3M per mm². Intel does not list transistor count or die size in the database. Clock speeds differ substantially: Intel runs at a 300 MHz base and 800 MHz boost, while AMD runs at 780 MHz base and 855 MHz boost. AMD's higher clocks help close the gap in some metrics, but the Intel part's wider execution resources win the compute race.

Memory architecture is a fundamental split. Intel uses system shared memory with system dependent bandwidth. AMD uses 4 GB of dedicated DDR3 at 1000 MHz (2 Gbps effective), on a 64-bit bus, yielding 16.00 GB/s of bandwidth. The bus interface also differs: Intel uses a Ring Bus, AMD uses PCIe 3.0 x8. Display outputs are motherboard dependent for Intel and portable device dependent for AMD. TDP is listed as 15 W for Intel, while AMD has no TDP recorded.

API support differs in modern versions: Intel supports OpenGL 4.4 and Vulkan 1.0, while AMD supports OpenGL 4.6 and Vulkan 1.2.170. Both support DirectX 12 (11_1). This makes AMD the better choice for applications that require newer OpenGL or Vulkan features.

Where Each One Wins

The Intel Iris Pro Graphics P6300 wins in OpenCL compute. The recorded Geekbench OpenCL score is 5712 for Intel versus 5152 for AMD, a 10.9% advantage. The Intel part also wins on texture rate (38.40 GTexel/s vs 17.10 GTexel/s) and FP32 throughput (614.4 GFLOPS vs 547.2 GFLOPS). Its 48 TMUs versus 20 give Intel a 2.25x lead in texture fill capacity. For workloads that hammer texture sampling or general compute shaders, Intel is the winner.

The AMD Radeon R5 M430 wins on rasterization throughput. Its 8 ROPs and 6.840 GPixel/s pixel rate exceed Intel's 6 ROPs and 4.800 GPixel/s by 42.5% in pixel throughput. AMD also wins on memory: dedicated 4 GB of DDR3 versus system shared memory, with a defined 16.00 GB/s bandwidth. For scenarios where frame buffer writes and memory locality matter, AMD has the edge.

AMD also wins on software compatibility in the database. OpenGL 4.6 and Vulkan 1.2.170 support are both newer than Intel's OpenGL 4.4 and Vulkan 1.0. If you have an application that mandates Vulkan 1.2 or OpenGL 4.5+, the AMD part is the only one of the two that qualifies.

In the nearest rival comparisons, Intel sits within 0.1% of the NVIDIA GeForce GTX 670MX (5721) and within 0.3% of the GTX 550 Ti (5731). AMD sits within 0.3% of the FirePro W4170M (5034) and just 0.9% below the R7 M340 (5063). Intel's closest rival delta is 0.1% below the GTX 670MX, meaning it trades blows with that GPU, while AMD's closest rival is 0.4% above the R7 Graphics. Intel is 1.9% ahead of the Quadro M500M, and AMD is 0.8% ahead of the Quadro 4000.

Head-to-Head Benchmarks

The only recorded head-to-head benchmark is Geekbench OpenCL. The Intel Iris Pro Graphics P6300 scores 5712, while the AMD Radeon R5 M430 scores 5152. The delta is 10.9% in Intel's favor. This is a decisive win for the Intel part in the most common compute benchmark for integrated and low-end discrete GPUs.

The AMD Radeon R5 M430 has a second benchmark entry, Geekbench Vulkan, with a score of 4884. The Intel part has no Vulkan score recorded. However, Intel's Vulkan support is limited to version 1.0, while AMD supports Vulkan 1.2.170. This suggests the AMD part is more capable in Vulkan workloads, though no direct comparison is recorded.

Looking at the average benchmark scores, Intel's average is 5712, and AMD's average is 5018 (the average of its two recorded scores). The Intel part's percentile ranking is 33rd versus AMD's 30th. While the gap is modest in percentile terms, the 10.9% OpenCL delta is the headline number.

The nearest rival data underscores how close these parts are to their peers. Intel's closest rival, the NVIDIA GeForce GTX 670MX, scores 5721, just 0.1% above Intel. The GTX 550 Ti scores 5731, 0.3% above. AMD's closest rival, the R7 M340, scores 5063, which is 0.9% above the R5 M430. The FirePro W4170M scores 5034, 0.3% below AMD. This places both parts in a tight cluster of low-end mobile GPUs, but Intel is consistently at the top of that cluster.

Texture rate is another major win for Intel. At 38.40 GTexel/s, the Intel part delivers more than double the AMD's 17.10 GTexel/s. This is a 124.6% difference. FP32 compute also favors Intel: 614.4 GFLOPS versus 547.2 GFLOPS, a 12.3% advantage. These metrics align with the OpenCL benchmark result.

AMD wins in pixel rate: 6.840 GPixel/s versus 4.800 GPixel/s, a 42.5% advantage. This is driven by AMD's 8 ROPs versus Intel's 6, despite Intel's higher shader and TMU counts. Clock speeds also favor AMD: 780 MHz base and 855 MHz boost versus Intel's 300 MHz base and 800 MHz boost. The higher boost clock helps AMD's pixel throughput.

The memory situation is a clear differentiator. AMD provides 4 GB of dedicated DDR3 at 16.00 GB/s on a 64-bit bus. Intel's memory is system shared with bandwidth marked as system dependent. In practice, this means AMD has predictable memory performance, while Intel's performance depends entirely on the host system's memory configuration.
