Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon R7 M460 is built on the GCN 3.0 architecture, using the Meso chip, and it belongs to the Gem System generation under the R7 M400 series. The Intel Iris Pro Graphics P6300, on the other hand, uses the Broadwell GT3e die with Intel's Generation 8.0 architecture, placed in the HD Graphics-W (Broadwell) generation.

Manufacturing processes diverge sharply. AMD relies on TSMC's 28 nm node, with a transistor count of 1,550 million packed into a die size of 125 mm². That yields a transistor density of 12.4 million transistors per square millimeter. Intel, using its own foundry, employs a 14 nm process for the Broadwell GT3e, though the database does not record transistor count, die size, or density for that chip. The newer, smaller process node for Intel suggests better power efficiency per transistor, but the AMD chip's larger die and higher transistor count provide raw compute muscle.

The memory subsystem is a major architectural fork. The AMD Radeon R7 M460 carries 2 GB of dedicated GDDR5 memory on a 64-bit bus, with a bandwidth of 36.00 GB/s and a memory clock of 1125 MHz (4.5 Gbps effective). The Intel Iris Pro Graphics P6300 uses System Shared memory, meaning it has no dedicated VRAM; it pulls from the system's main memory pool, with the bus width also listed as System Shared and bandwidth described as System Dependent. This is a classic discrete versus integrated GPU split, and it has direct implications for performance consistency: the AMD part's dedicated memory avoids contention with the CPU, while the Intel part's shared memory can become a bottleneck depending on the system configuration.

Compute resources show a partial overlap. Both GPUs have 384 shading units. That is where the similarity ends. The Intel chip has 48 texture mapping units (TMUs) versus 24 on the AMD part, giving Intel a 2:1 advantage in texture processing hardware. The AMD chip counters with 8 render output units (ROPs) versus 6 on Intel, a smaller but relevant edge in pixel processing.

The Intel part includes an integrated design with a 15 W TDP and the slot width listed as IGP, confirming its place inside a processor package. The AMD Radeon R7 M460 does not have a recorded TDP or slot width in the database, but its dedicated memory and separate chip design indicate a discrete mobile GPU. The bus interface also differs: AMD uses PCIe 3.0 x8, while Intel connects via the Ring Bus, which is typical for an integrated GPU sharing the processor's internal fabric.

API support leans toward AMD. The Radeon R7 M460 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The Intel Iris Pro Graphics P6300 supports DirectX 12 (11_1), OpenGL 4.4, and Vulkan 1.0. The AMD part has a newer feature level for DirectX and a significantly more recent Vulkan revision.

Specification Differences

The recorded specifications show clear divergence in several categories. Process node: AMD is on 28 nm, Intel on 14 nm. Foundry: TSMC for AMD, Intel for the Iris Pro part. Transistor count: AMD has 1,550 million, Intel has no recorded value. Die size: AMD at 125 mm², Intel not recorded. Transistor density: AMD at 12.4M per mm², Intel not recorded.

Clock speeds differ substantially. The AMD Radeon R7 M460 runs at a base clock of 730 MHz and boosts to 1024 MHz. The Intel Iris Pro Graphics P6300 has a base clock of 300 MHz and boosts to 800 MHz. The AMD chip's base clock is more than double Intel's, and its boost clock is 224 MHz higher.

Memory configuration is another point of divergence. AMD has 2 GB of GDDR5 on a 64-bit bus with 36.00 GB/s bandwidth. Intel has System Shared memory, System Shared type, System Shared bus width, and System Dependent bandwidth. The AMD part's dedicated memory is a structural advantage for GPU workloads.

Texture and pixel throughput split the two. AMD's texture rate is 24.58 GTexel/s; Intel's is 38.40 GTexel/s. AMD's pixel rate is 8.192 GPixel/s; Intel's is 4.800 GPixel/s. The FP32 compute rating is 786.4 GFLOPS for AMD and 614.4 GFLOPS for Intel, a 28 percent difference in AMD's favor. AMD also lists FP16 at 786.4 GFLOPS with a 1:1 ratio, while Intel has no recorded FP16 value.

The TDP is recorded only for Intel at 15 W. The slot width is IGP for Intel and not listed for AMD. Display outputs are Motherboard Dependent for Intel and not listed for AMD. The bus interface is PCIe 3.0 x8 for AMD and Ring Bus for Intel.

API versions differ as noted: DirectX 12 (12_0) versus DirectX 12 (11_1), OpenGL 4.6 versus 4.4, and Vulkan 1.2.170 versus 1.0. Release dates also differ, with AMD launching on 2016-05-14 and Intel on 2014-09-04. Both are marked end-of-life in the database.

Where Each One Wins

The AMD Radeon R7 M460 takes the headline win in the only recorded benchmark, the Geekbench OpenCL test, with a 15.8 percent advantage. Its FP32 compute of 786.4 GFLOPS versus 614.4 GFLOPS for Intel reinforces that lead in general-purpose compute tasks. The higher pixel rate, 8.192 GPixel/s against 4.800 GPixel/s, suggests AMD is better suited for fill-rate-bound scenarios such as high-resolution rendering or heavy fragment shader work. The dedicated 2 GB GDDR5 memory with a fixed 36.00 GB/s bandwidth gives AMD a predictable memory performance profile, which is valuable for workloads that repeatedly access textures or framebuffers.

The Intel Iris Pro Graphics P6300, despite losing the compute benchmark, has its own areas of strength. Its texture rate of 38.40 GTexel/s is 56 percent higher than AMD's 24.58 GTexel/s, which means Intel's 48 TMUs can feed texture-heavy effects faster than AMD's 24 TMUs. The 14 nm process node, while not directly benchmarked, implies better power efficiency per clock, and the 15 W TDP confirms a low-power envelope suitable for thin-and-light systems. The Ring Bus interface allows the integrated GPU to share data with the CPU without a separate PCIe link, which can reduce latency for certain interleaved CPU-GPU workloads.

In terms of architecture support, AMD wins on modern API maturity. DirectX 12 (12_0) and Vulkan 1.2.170 are newer specifications than Intel's DirectX 12 (11_1) and Vulkan 1.0, so the AMD part is more likely to support recent game features and compute extensions.

The Verdict

The data points to the AMD Radeon R7 M460 as the stronger GPU for raw compute and pixel throughput. Its 6612 OpenCL score beats the Intel Iris Pro Graphics P6300's 5712 by 15.8 percent, placing it at the 38th percentile versus Intel's 33rd. The AMD chip also delivers 786.4 GFLOPS of FP32 performance, 28 percent above Intel's 614.4 GFLOPS, and its 8.192 GPixel/s pixel rate is 70 percent higher than Intel's 4.800 GPixel/s. For users prioritizing OpenCL compute, higher resolutions, or modern API support, the AMD part is the clear choice.

The Intel Iris Pro Graphics P6300, however, should not be dismissed. Its 48 TMUs and 38.40 GTexel/s texture rate outperform the AMD part significantly, which could translate to better results in texture-heavy applications that do not rely on raw FP32 or pixel fill. The 15 W TDP and integrated design make it suitable for power-constrained systems where a discrete GPU is not an option. The 14 nm process also indicates a more modern manufacturing approach, even if the database does not record its transistor count.

For a system builder choosing between these two end-of-life parts, the decision hinges on workload type. If the task involves general-purpose compute, high pixel fill, or modern API features, the AMD Radeon R7 M460 wins outright. If the task is texture-bound and power efficiency is paramount, the Intel Iris Pro Graphics P6300 offers a viable alternative despite its lower benchmark score. The database's single head-to-head result, however, gives the overall performance crown to AMD.
