AMD Radeon R7 M340 vs Intel Iris Pro Graphics P6300 Comparison

Intel Iris Pro Graphics P6300 vs AMD Radeon R7 M340

The database places these two mobile graphics solutions close in the overall standings, but their benchmark results reveal distinct strengths. The Intel Iris Pro Graphics P6300 holds a 33rd percentile rank among all GPUs, while the AMD Radeon R7 M340 sits at the 30th percentile. Their average benchmark scores, 5712 for the Intel part and 5063 for the AMD part, show a meaningful gap, but the nature of that gap and where each chip excels matters more than the raw average. The Intel solution wins the only shared benchmark, but the AMD chip offers its own capabilities in API support and raw specifications that the Intel part cannot match.

Where Each One Wins

The Intel Iris Pro Graphics P6300 wins on raw compute performance in the OpenCL workload. It scored 5712 in Geekbench OpenCL, which is 15.8% ahead of the AMD Radeon R7 M340’s 4932 in the same test. This makes the Intel part the stronger choice for general-purpose compute tasks and any application that relies on OpenCL acceleration. Its performance also lands it in close company with discrete mobile GPUs like the NVIDIA GeForce GTX 670MX, which scores 5721, and the NVIDIA GeForce GTX 550 Ti at 5731, meaning the Intel integrated solution competes with older discrete parts.

The AMD Radeon R7 M340 wins on modern API readiness and memory configuration. It supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170, while the Intel part only reaches DirectX 12 (11_1), OpenGL 4.4, and Vulkan 1.0. The AMD chip also has dedicated 2 GB of DDR3 memory on a 64-bit bus with 16.00 GB/s of bandwidth, whereas the Intel part relies on system shared memory with bandwidth described as system dependent. For games or applications that require modern graphics APIs, the AMD chip is the more future-proof option, even if its raw OpenCL score is lower.

Head-to-Head Benchmarks

The only direct benchmark comparison recorded in the database is Geekbench OpenCL, and the Intel Iris Pro Graphics P6300 takes a clear victory. The Intel part scored 5712 against the AMD Radeon R7 M340’s 4932, a delta of 15.8%. This is a substantial margin in GPU compute terms, and it places the Intel part firmly ahead in any OpenCL-based workload.

Looking at the surrounding rival data, the Intel part’s 5712 score sits in a tight cluster. The NVIDIA GeForce GTX 670MX is only 0.1% behind at 5721, and the NVIDIA GeForce GTX 550 Ti is 0.3% behind at 5731. The AMD Radeon HD 8790M trails by 0.4% at 5691, and the NVIDIA Quadro M500M is 1.9% behind at 5604. This means the Intel integrated GPU performs at the level of older mid-range discrete mobile GPUs, which is a notable achievement for an integrated solution.

The AMD Radeon R7 M340, on the other hand, sits at 4932 in OpenCL, and its nearest rivals are all AMD parts. The AMD Radeon R7 240 matches it exactly at 5063, the AMD FirePro W4170M is 0.6% behind at 5034, the AMD Radeon R5 M430 is 0.9% behind at 5018, and the AMD Radeon R7 Graphics is 1.3% behind at 4998. The AMD chip also has a Geekbench Vulkan score of 5193, which the Intel part does not have recorded, indicating the AMD chip can handle Vulkan workloads while the Intel part’s Vulkan support is limited to version 1.0.

Specification Differences

The two GPUs differ substantially in their core configurations. The Intel Iris Pro Graphics P6300 has 384 shading units, 48 texture mapping units, and 6 raster operation pipelines. The AMD Radeon R7 M340 has 320 shading units, 20 texture mapping units, and 8 raster operation pipelines. This gives the Intel part more shading and texturing hardware, while the AMD part has more ROPs.

Clock speeds also differ. The Intel part runs at a base clock of 300 MHz with a boost clock of 800 MHz. The AMD part runs much higher, with a base clock of 943 MHz and a boost clock of 1021 MHz. Despite the higher clocks, the AMD chip’s lower shading unit count and TMU count result in lower texture and pixel throughput in some metrics. The Intel part achieves a texture rate of 38.40 GTexel/s, while the AMD part manages 20.42 GTexel/s. However, the AMD part wins on pixel rate, delivering 8.168 GPixel/s against the Intel part’s 4.800 GPixel/s.

Memory is another clear divider. The Intel Iris Pro Graphics P6300 shares system memory, with its bus width and bandwidth both listed as system shared and system dependent. The AMD Radeon R7 M340 has 2 GB of dedicated DDR3 memory on a 64-bit bus with 16.00 GB/s of bandwidth. The memory clock on the AMD part is 1000 MHz, or 2 Gbps effective.

The process nodes differ as well. The Intel part is built on a 14 nm process at Intel’s foundry, while the AMD part uses a 28 nm process at TSMC. The AMD chip has 1,550 million transistors on a 125 mm² die, giving a transistor density of 12.4M per mm². The Intel part’s transistor count and die size are not recorded in the database. The Intel part carries a 15 W TDP, while the AMD part’s TDP is not listed.

Interface and output differences also exist. The Intel part uses a Ring Bus interface and is an IGP, meaning it is integrated into the processor package. The AMD part uses PCIe 3.0 x8. The Intel part’s display outputs are motherboard dependent, while the AMD part’s display outputs are not recorded.

Architecture Differences

The Intel Iris Pro Graphics P6300 is built on the Broadwell GT3e chip, using Intel’s Generation 8.0 architecture from the HD Graphics-W (Broadwell) generation. This is a 14 nm part fabricated by Intel. The AMD Radeon R7 M340 uses the Meso chip with GCN 3.0 architecture, belonging to the Gem System (R7 M300) generation. It is a 28 nm part fabricated by TSMC.

Shading unit counts differ, with the Intel part featuring 384 shading units against the AMD part’s 320. The Intel part also has 48 TMUs, more than double the AMD part’s 20, which explains its higher texture rate of 38.40 GTexel/s versus 20.42 GTexel/s. The AMD part counters with 8 ROPs versus the Intel part’s 6, enabling its higher pixel rate of 8.168 GPixel/s against 4.800 GPixel/s.

The Intel part’s FP32 performance is 614.4 GFLOPS, while the AMD part achieves 653.4 GFLOPS. The AMD part also supports FP16 at 653.4 GFLOPS with a 1:1 ratio, while the Intel part has no recorded FP16 capability. The AMD part’s higher FP32 and FP16 throughput comes from its higher clock speeds, despite having fewer shading units.

API support is a major architectural difference. The Intel part supports DirectX 12 (11_1), OpenGL 4.4, and Vulkan 1.0. The AMD part supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. This gives the AMD part a clear advantage in modern API compatibility, which matters for newer games and applications that take advantage of Vulkan or updated DirectX features. The AMD part’s predecessor is listed as Solar System, with a successor of Polaris Mobile, while the Intel part has no recorded predecessor or successor.

The Verdict

The Intel Iris Pro Graphics P6300 is the choice for OpenCL compute performance and raw shading throughput. Its 5712 OpenCL score is 15.8% ahead of the AMD Radeon R7 M340, and it matches or beats older discrete NVIDIA mobile GPUs like the GeForce GTX 670MX and GeForce GTX 550 Ti. The Intel part also has a much higher texture rate at 38.40 GTexel/s, making it better suited for texturing-heavy workloads. Its 384 shading units and 48 TMUs give it a hardware advantage that clock speed alone cannot overcome.

The AMD Radeon R7 M340 is the choice for modern API support and memory configuration. It offers DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170, which are all newer than what the Intel part supports. It also has 2 GB of dedicated DDR3 memory, which avoids the performance variability of system shared memory. Its pixel rate of 8.168 GPixel/s is nearly double the Intel part’s 4.800 GPixel/s, and its FP32 throughput of 653.4 GFLOPS edges out the Intel part’s 614.4 GFLOPS.

The recorded data shows a clear tradeoff. Users who prioritize compute workloads, OpenCL acceleration, and texture throughput should select the Intel Iris Pro Graphics P6300. Users who need modern graphics API support, dedicated memory, and higher pixel fill rates should select the AMD Radeon R7 M340. The Intel part wins the only head-to-head benchmark, but the AMD part offers capabilities that the benchmark does not measure. Both are end-of-life products, so the decision rests on which workloads matter more for the intended use case.
