AMD Radeon R7 M370 vs Intel Iris Pro Graphics P6300 Comparison

Where Each One Wins

The benchmark data splits cleanly between the two mobile graphics solutions. The AMD Radeon R7 M370 wins the only directly comparable test, the Geekbench OpenCL benchmark, by a substantial 23.7% margin. That single victory gives it a 1-0 win tally in the head-to-head comparison.

However, the Intel Iris Pro Graphics P6300 enters the comparison with a notable handicap: it has only one recorded benchmark score in the database, the Geekbench OpenCL result. The AMD part has two recorded scores, adding a Geekbench Vulkan result of 6465 to its OpenCL score of 7063. This means the Intel solution has no recorded Vulkan performance data, so any discussion of its Vulkan capabilities must remain qualitative.

Looking at the broader competitive landscape, the AMD Radeon R7 M370 sits at the 38th percentile of all GPUs, while the Intel Iris Pro Graphics P6300 sits at the 33rd percentile. The AMD part's average benchmark score of 6764 places it slightly ahead of its nearest rivals: it trails the AMD FirePro M5100 by 1% (6830 average), edges out the NVIDIA GeForce GT 1010 by 1% (6698 average), and leads the AMD Radeon R7 M460 by 2.3% (6612 average). The Intel part's average score of 5712 places it within a narrow band around its rivals: it trails the NVIDIA GeForce GTX 670MX by 0.1% (5721 average) and the NVIDIA GeForce GTX 550 Ti by 0.3% (5731 average), while leading the AMD Radeon HD 8790M by 0.4% (5691 average) and the NVIDIA Quadro M500M by 1.9% (5604 average).

The use-case split is therefore straightforward. The AMD Radeon R7 M370 is the stronger choice for compute-oriented workloads that stress OpenCL and Vulkan performance. The Intel Iris Pro Graphics P6300, being an integrated processor graphics solution with a 15 W TDP, is positioned for systems where power efficiency and integration matter more than raw compute throughput.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon R7 M370 uses the GCN 1.0 architecture on a 28 nm TSMC process, packing 950 million transistors into a 77 mm² die. The chip, codenamed Litho, belongs to the Gem System generation within the R7 M300 series. Its transistor density works out to 12.3 million transistors per square millimeter.

The Intel Iris Pro Graphics P6300 uses Intel's Generation 8.0 architecture on a 14 nm process, with the chip being Broadwell GT3e. It belongs to the HD Graphics-W generation within the Broadwell family. The process node advantage (14 nm versus 28 nm) allows Intel to integrate the GPU directly onto the processor package, using a ring bus interface rather than a discrete PCIe connection.

Both GPUs feature 384 shading units, but the similarity ends there. The AMD part has 24 texture mapping units and 8 raster operations pipelines, while the Intel part has double the TMUs at 48 but fewer ROPs at 6. This configuration explains the texture rate advantage for Intel: 38.40 GTexel/s versus 23.04 GTexel/s for AMD. However, the AMD part's pixel rate of 7.680 GPixel/s exceeds Intel's 4.800 GPixel/s due to the higher ROP count.

Clock speeds also differ significantly. The AMD Radeon R7 M370 runs at a base clock of 875 MHz with a boost clock of 960 MHz, while the Intel Iris Pro Graphics P6300 runs at a much lower base of 300 MHz with an 800 MHz boost. The AMD part's memory clock is 900 MHz, translating to 3.6 Gbps effective on GDDR5 memory. The Intel part uses system shared memory with a system dependent bandwidth.

Memory configuration is another major differentiator. The AMD Radeon R7 M370 has 2 GB of dedicated GDDR5 memory on a 128-bit bus, delivering 57.60 GB/s of bandwidth. The Intel Iris Pro Graphics P6300 uses system shared memory with a system dependent bandwidth, meaning its performance depends heavily on the host system's memory configuration.

The FP32 compute output reflects these architectural choices: the AMD part produces 737.3 GFLOPS, while the Intel part produces 614.4 GFLOPS. This 20% difference in theoretical compute aligns with the 23.7% difference seen in the OpenCL benchmark.

Feature support shows some divergence. Both support DirectX 12 (11_1) and Vulkan, but the AMD part supports OpenGL 4.6 and Vulkan 1.2.170, while the Intel part supports OpenGL 4.4 and Vulkan 1.0. The AMD Radeon R7 M370 uses a PCIe 3.0 x8 interface, while the Intel part uses a ring bus, reflecting its integrated nature.

Head-to-Head Benchmarks

The only directly comparable benchmark in the database is Geekbench OpenCL. In that test, the AMD Radeon R7 M370 scores 7063 against the Intel Iris Pro Graphics P6300's 5712. This represents a 23.7% advantage for the AMD part.

To put that delta in context, the AMD part's nearest rival comparisons show much smaller margins. The AMD FirePro M5100 leads the Radeon R7 M370 by just 1%, and the NVIDIA GeForce GT 1010 trails by 1%. A 23.7% difference is therefore far outside the typical competitive band for either GPU. The Intel part's nearest rivals all sit within 1.9% of its score, making the margin against the AMD Radeon R7 M370 a significant outlier.

The AMD Radeon R7 M370 also has a recorded Geekbench Vulkan score of 6465. This score sits below its OpenCL result, suggesting the Vulkan driver path is slightly less optimized, but still represents a solid compute result. With no Vulkan score recorded for the Intel part, the AMD solution demonstrates broader API coverage in the measured data.

The pixel rate comparison further favors AMD: 7.680 GPixel/s versus 4.800 GPixel/s, a 60% advantage. The texture rate comparison favors Intel: 38.40 GTexel/s versus 23.04 GTexel/s, a 66.7% advantage. These theoretical rates suggest the Intel part might handle texture-heavy workloads better, while the AMD part excels at fill-rate-bound tasks. However, the recorded OpenCL benchmark shows the AMD part winning overall compute performance by a wide margin.

The FP32 throughput difference of 737.3 GFLOPS versus 614.4 GFLOPS (a 20% advantage for AMD) aligns closely with the OpenCL benchmark delta, indicating that the compute advantage is consistent across theoretical and measured performance.

The Verdict

The data points to a clear winner for compute-heavy workloads. The AMD Radeon R7 M370 leads in the only head-to-head benchmark, outperforming the Intel Iris Pro Graphics P6300 by 23.7% in Geekbench OpenCL. This margin is consistent with its theoretical FP32 advantage of 737.3 GFLOPS versus 614.4 GFLOPS, and its pixel rate advantage of 7.680 GPixel/s versus 4.800 GPixel/s.

The AMD part also demonstrates broader software support in the measured data. It has recorded Vulkan performance (6465 in Geekbench Vulkan) while the Intel part has none, and it supports newer API versions including OpenGL 4.6 and Vulkan 1.2.170. The Intel part's older API support (OpenGL 4.4, Vulkan 1.0) may limit compatibility with newer applications.

The Intel Iris Pro Graphics P6300's sole advantage in the theoretical specifications is its texture rate: 38.40 GTexel/s versus 23.04 GTexel/s, driven by its 48 TMUs against AMD's 24. This could translate to better performance in texture-bound workloads, but the recorded OpenCL benchmark does not reflect this advantage. Additionally, the Intel part's 15 W TDP and integrated design make it suitable for compact, power-conscious systems where a discrete GPU is not an option.

For users selecting a GPU based on measured compute performance, the AMD Radeon R7 M370 is the stronger choice. Its 38th percentile ranking versus the Intel part's 33rd percentile, combined with a 23.7% head-to-head win, positions it clearly ahead in general compute tasks. The Intel part remains a viable option only where integration and power constraints take priority over raw performance, as its system shared memory and motherboard-dependent display outputs indicate a design focused on simplicity rather than peak throughput.
