AMD Radeon R7 M265 vs Intel Iris Pro Graphics P6300 Comparison

Head-to-Head Benchmarks

The recorded data shows a single benchmark comparison between these two mobile graphics solutions, and the result is decisive. In the Geekbench OpenCL test, the Intel Iris Pro Graphics P6300 scores 5712 points, while the AMD Radeon R7 M265 scores 4929 points. That is a 15.9% advantage for the Intel part. This is not a marginal victory; it is a substantial gap that places the two chips in different performance tiers within the database.

The Intel Iris Pro Graphics P6300 sits at the 33rd percentile of all GPUs in the database, while the AMD Radeon R7 M265 sits at the 29th percentile. The four-point percentile gap reflects the raw score difference. Looking at the nearest rivals for the Intel part, its score of 5712 places it within a very tight cluster: it is 0.1% behind the NVIDIA GeForce GTX 670MX (5721), 0.3% behind the NVIDIA GeForce GTX 550 Ti (5731), 0.4% ahead of the AMD Radeon HD 8790M (5691), and 1.9% ahead of the NVIDIA Quadro M500M (5604). Essentially, the Intel part trades blows with these established discrete-class GPUs, landing nearly dead even with the GTX 670MX and GTX 550 Ti.

For the AMD Radeon R7 M265, the nearest rivals tell a different story. Its score of 4929 puts it directly alongside the AMD Radeon R7 M360 (4931, a 0% delta), the AMD FirePro W5130M (4904, 0.5% ahead), the NVIDIA GeForce RTX 5060 Ti 8 GB (4901, 0.6% ahead), and the NVIDIA GeForce GTS 450 (4893, 0.7% ahead). The R7 M265 is essentially tied with these parts, but the entire cluster is well below the Intel Iris Pro's cluster. The 15.9% delta between the two reviewed chips is far larger than any of the deltas within their respective rival groups.

The head-to-head table confirms this with a clean sweep: the Intel part wins the single recorded benchmark, and the AMD part wins none. There is no scenario in the recorded data where the AMD Radeon R7 M265 pulls ahead. The Intel Iris Pro Graphics P6300 is not merely faster; it is faster by a margin that separates it from the entire peer group of the AMD part.

Architecture Differences

The two chips come from fundamentally different design philosophies. The Intel Iris Pro Graphics P6300 is built on Intel's Broadwell GT3e die, using the Generation 8.0 architecture, and it is manufactured on a 14 nm process at Intel's own foundry. The AMD Radeon R7 M265 uses the Opal chip with GCN 1.0 architecture, built on a 28 nm process at TSMC. The process node difference is significant: 14 nm versus 28 nm means the Intel part uses a more advanced manufacturing technology, which typically allows for higher transistor density and lower power consumption per unit of performance.

The Intel part integrates its graphics into the processor package. It has a base clock of 300 MHz and a boost clock of 800 MHz. The AMD part runs at a base clock of 725 MHz with a boost clock of 825 MHz. Despite the AMD part's higher clocks, the Intel part still wins the benchmark, which points to architectural efficiency advantages rather than raw clock speed.

Memory configurations are starkly different. The Intel Iris Pro Graphics P6300 uses system shared memory with a system-dependent bandwidth, meaning it relies on the host system's RAM. The AMD Radeon R7 M265 has dedicated memory: 2 GB of DDR3 on a 128-bit bus, with a fixed bandwidth of 28.80 GB/s and a memory clock of 900 MHz (1800 Mbps effective). Having dedicated VRAM is typically an advantage, yet the Intel part overcomes that handicap in the benchmark.

The compute resources are organized differently. Both parts have 384 shading units, but the Intel part has 48 texture mapping units (TMUs) and 6 render output units (ROPs), while the AMD part has 24 TMUs and 8 ROPs. The Intel part's higher TMU count (double the AMD's) contributes to its texture rate of 38.40 GTexel/s versus the AMD's 19.80 GTexel/s, a 94% advantage in texture throughput. The AMD part has a higher pixel rate at 6.600 GPixel/s versus the Intel's 4.800 GPixel/s, a 37.5% advantage in fill rate. The FP32 compute is close: the Intel part delivers 614.4 GFLOPS, and the AMD part delivers 633.6 GFLOPS, a 3.1% edge for AMD, yet the Intel part still wins the OpenCL benchmark.

The AMD part lists a transistor count of 950 million on a 77 mm² die, with a transistor density of 12.3 million transistors per square millimeter. The Intel part does not have these figures recorded in the database. The AMD part uses a PCIe 3.0 x8 bus interface, while the Intel part uses a Ring Bus, reflecting its integrated nature. In terms of API support, both support DirectX 12 (11_1), but the AMD part offers OpenGL 4.6 versus the Intel's 4.4, and Vulkan 1.2.170 versus the Intel's 1.0. The AMD part also has a documented predecessor (Solar System) and successor (Polaris Mobile), while the Intel part's lineage is not recorded.

Where Each One Wins

Based strictly on the recorded benchmark results, the Intel Iris Pro Graphics P6300 wins the only head-to-head comparison available. The 15.9% lead in Geekbench OpenCL indicates that for general-purpose compute workloads, which is what OpenCL measures, the Intel part is the stronger choice. This is notable because the Intel part is an integrated graphics processor (IGP) with system shared memory, while the AMD part is a discrete-class mobile GPU with dedicated 2 GB VRAM. The Intel part's victory suggests that its Broadwell GT3e architecture, 48 TMUs, and 14 nm process efficiency compensate for its lack of dedicated memory.

The AMD Radeon R7 M265 does have its own advantages in the data, even if they do not translate to a benchmark win. Its pixel rate of 6.600 GPixel/s is 37.5% higher than the Intel's 4.800 GPixel/s, which could matter for workloads that are fill-rate bound, such as certain rasterization tasks. Its FP32 compute of 633.6 GFLOPS is modestly higher than the Intel's 614.4 GFLOPS, indicating that pure compute peak is slightly in AMD's favor. The AMD part also has a higher base clock (725 MHz versus 300 MHz) and boost clock (825 MHz versus 800 MHz), and it supports newer API versions (OpenGL 4.6 and Vulkan 1.2.170 versus OpenGL 4.4 and Vulkan 1.0), which could matter for software compatibility in newer titles.

However, the database records zero wins for the AMD part. In the use cases where the AMD part's higher pixel rate or newer APIs would be relevant, there is no benchmark data to confirm an actual advantage. The only measured outcome is the OpenCL score, and the Intel part wins it decisively. For texture-heavy workloads, the Intel part's 38.40 GTexel/s is nearly double the AMD's 19.80 GTexel/s, so the Intel part is likely to dominate in any scenario that stresses texture sampling.

The Verdict

The data points to a clear conclusion: the Intel Iris Pro Graphics P6300 is the faster GPU in this pairing. Its Geekbench OpenCL score of 5712 versus 4929 for the AMD Radeon R7 M265 represents a 15.9% performance gap, and the Intel part's percentile ranking (33rd versus 29th) confirms that this is not a statistical fluke. Users who prioritize compute performance in OpenCL workloads should choose the Intel part without hesitation.

The AMD Radeon R7 M265 is not without merit. Its dedicated 2 GB VRAM, higher pixel rate, and slightly higher FP32 peak could make it preferable in scenarios where those characteristics matter more than raw OpenCL compute. It also offers newer API support, which could be relevant for software that leverages OpenGL 4.6 or Vulkan 1.2.170 features. However, the database provides no benchmark evidence that these advantages translate into real-world wins. The AMD part's nearest rivals are all clustered within 0.7% of its score, indicating that it is a typical mid-tier mobile GPU of its era, whereas the Intel part's nearest rivals include the NVIDIA GeForce GTX 670MX and GTX 550 Ti, which are discrete desktop-class parts.

For a user deciding between these two, the choice depends on the workload. If the primary use is OpenCL compute, general GPU acceleration, or texture-heavy rendering, the Intel Iris Pro Graphics P6300 is the better pick. If the use case specifically requires dedicated VRAM, higher pixel fill rate, or newer API versions, the AMD Radeon R7 M265 has documented advantages, but none of them are validated by a benchmark win in the database. The verdict is straightforward: the Intel part wins the measured comparison.
