AMD Radeon R7 M360 vs Intel Iris Pro Graphics P6300 Comparison

Where Each One Wins

The Intel Iris Pro Graphics P6300 takes the single recorded OpenCL benchmark decisively, scoring 5712 against the AMD Radeon R7 M360's 4638. That is a 23.2% advantage, and it is the only head-to-head benchmark where both parts have a recorded score. The Intel part also holds a higher overall percentile rank, sitting at 33 compared to the AMD part's 29, which places it above a larger share of all GPUs in the database.

Where the AMD Radeon R7 M360 makes its case is in API coverage and raw compute peaks. It records a Vulkan score of 5223, a test the Intel part has no entry for, and its FP32 peak of 864.0 GFLOPS is higher than the Intel part's 614.4 GFLOPS. The AMD part also supports FP16 at a 1:1 ratio (864.0 GFLOPS), while the Intel part lists no FP16 capability at all. For workloads that lean on Vulkan or half-precision math, the AMD part has the edge on paper.

The Intel part wins on memory flexibility in one sense: it uses system shared memory, which means bandwidth is system dependent. That can be a strength or a weakness depending on the platform. In a dual-channel system with fast RAM, the Intel part could see effective bandwidth far above the AMD part's fixed 14.40 GB/s, but in a single-channel or slow-memory configuration, it could be far below. The AMD part's dedicated 2 GB of DDR3 on a 64-bit bus is predictable and consistent, but it is capped at 14.40 GB/s regardless of the host system.

For texture-heavy work, the Intel part has 48 TMUs versus the AMD part's 24, giving it a 38.40 GTexel/s texture rate against the AMD part's 27.00 GTexel/s. For pixel throughput, the AMD part reverses that with 8 ROPs and a 9.000 GPixel/s pixel rate versus the Intel part's 6 ROPs and 4.800 GPixel/s. So the split is clear: Intel for texture throughput and OpenCL, AMD for pixel fill, FP32 peak, and Vulkan.

Architecture Differences

These two parts come from completely different design philosophies. The Intel Iris Pro Graphics P6300 is built on Broadwell GT3e, part of Intel's Generation 8.0 architecture, on a 14 nm process at Intel's own foundry. It is an integrated graphics processor (IGP) with a Ring Bus interface, drawing a 15 W TDP. The AMD Radeon R7 M360 uses the Meso chip, based on GCN 3.0, built on a 28 nm process at TSMC, with 1,550 million transistors on a 125 mm² die. That gives AMD a transistor density of 12.4M per mm², which is a notable figure for the older node.

The transistor counts tell a story of design intent. The Intel part has no listed transistor count or die size in the database, but its 384 shading units, 48 TMUs, and 6 ROPs show a wide, shallow design focused on throughput per watt. The AMD part matches the 384 shading units but halves the TMUs to 24 and raises ROPs to 8. The AMD part's 28 nm process and higher clocks (1100 MHz base, 1125 MHz boost) push its FP32 peak to 864.0 GFLOPS, while the Intel part's lower clocks (300 MHz base, 800 MHz boost) cap its FP32 at 614.4 GFLOPS. The Intel part makes up for low clocks with more texture units and a much larger relative memory pool via system shared memory.

API support differs substantially. The Intel part lists DirectX 12 (11_1), OpenGL 4.4, and Vulkan 1.0. The AMD part lists DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The AMD part's newer API versions, especially the higher Vulkan revision, align with its recorded Vulkan benchmark score. The Intel part's older API set is consistent with its 2014 release date, versus the AMD part's 2015 release.

The AMD part also has a documented lineage: its predecessor is Solar System and its successor is Polaris Mobile. The Intel part has no predecessor or successor listed. Both are end-of-life products.

Head-to-Head Benchmarks

The database contains one head-to-head benchmark between these two parts, and it is a clear Intel victory. In Geekbench OpenCL, the Intel Iris Pro Graphics P6300 scores 5712 against the AMD Radeon R7 M360's 4638, a 23.2% delta. That is a substantial gap for two parts with the same shading unit count.

To put that in context, the Intel part's nearest rivals bracket it tightly: the NVIDIA GeForce GTX 670MX scores 5721 (0.1% ahead of the Intel part, effectively a tie in the noise margin of the test), the NVIDIA GeForce GTX 550 Ti scores 5731 (0.3% ahead), and the AMD Radeon HD 8790M scores 5691 (0.4% behind). The Intel part's OpenCL result places it in a cluster with those three desktop and mobile parts, all within a 0.4% band. The NVIDIA Quadro M500M is further back at 5604, 1.9% behind the Intel part.

The AMD Radeon R7 M360's average benchmark score across its recorded tests is 4931, which is the midpoint of its OpenCL score of 4638 and Vulkan score of 5223. Its nearest rivals are clustered around that figure: the AMD Radeon R7 M265 matches it at 4929 (0.0% delta), the AMD FirePro W5130M scores 4904 (0.6% behind), the NVIDIA GeForce RTX 5060 Ti 8 GB scores 4901 (0.6% behind), and the NVIDIA GeForce GTS 450 scores 4893 (0.8% behind). Note that the RTX 5060 Ti 8 GB appears in this rival list with a similar average score, which is a database quirk, but the recorded data is what it is.

The Intel part's single benchmark score of 5712 also serves as its average, since no other tests are recorded for it. The AMD part's two scores show a large internal gap: its Vulkan result (5223) is 12.6% higher than its OpenCL result (4638). That suggests the AMD part is better optimized for Vulkan workloads, or at least that its GCN 3.0 architecture handles that API more efficiently. The Intel part has no recorded Vulkan score, so no comparison is possible on that API.

The Verdict

The data points to a straightforward choice depending on workload. If the priority is OpenCL compute, the Intel Iris Pro Graphics P6300 is the clear winner: 5712 versus 4638, a 23.2% gap. Its 48 TMUs also give it a much higher texture rate (38.40 GTexel/s versus 27.00 GTexel/s), which matters for texture-bound tasks. Its lower 15 W TDP and IGP form factor mean it is the practical choice for a system where power and space are constrained.

If the priority is Vulkan support, pixel fill, or raw FP32 throughput, the AMD Radeon R7 M360 has the better profile. It records a Vulkan score of 5223, supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170, all newer than the Intel part's API set. Its 9.000 GPixel/s pixel rate is nearly double the Intel part's 4.800 GPixel/s, and its 864.0 GFLOPS FP32 peak is 40.6% higher than the Intel part's 614.4 GFLOPS. The AMD part also has dedicated 2 GB of DDR3 memory, which removes dependence on the host system's RAM configuration.

For a laptop or small form factor system where the integrated GPU is the only option, the Intel part is the better choice based on the recorded benchmark. For a system with a dedicated GPU slot and a workload that uses Vulkan or needs higher pixel throughput, the AMD part's feature set is more attractive. The Intel part's nearest rivals all land within a narrow band around its score, suggesting it sits in a competitive tier for its era. The AMD part's nearest rivals cluster around 4900, which is nearly 800 points below the Intel part's score, indicating the Intel part occupies a higher performance tier in the database.

The verdict from the recorded data: Intel for OpenCL and texture throughput, AMD for Vulkan, pixel fill, and peak compute. Neither part is a modern powerhouse, but the Intel part has the stronger benchmark record.
