AMD Radeon 880M vs Intel Iris Pro Graphics P580 Comparison

AMD Radeon 880M vs Intel Iris Pro Graphics P580

Head-to-Head Benchmarks

The recorded data shows a decisive outcome in the two directly comparable benchmark tests. The AMD Radeon 880M wins both head-to-head matchups, leaving the Intel Iris Pro Graphics P580 without a single recorded victory in this comparison. The margin of victory is substantial in both compute and graphics API workloads.

In the Geekbench OpenCL test, the AMD Radeon 880M scores 31,285 points against 9,082 points for the Intel Iris Pro Graphics P580. This translates to a 244.5% advantage for the AMD part, meaning the Radeon 880M delivers more than three times the raw compute performance in this OpenCL workload. The gap is not a marginal one; it represents a generational leap in processing capability that separates the two integrated graphics solutions by a wide margin.

The Geekbench Vulkan test shows an even more pronounced disparity. The AMD Radeon 880M records 40,006 points, while the Intel Iris Pro Graphics P580 manages only 5,258 points. The delta reaches 660.9% in favor of the AMD solution, indicating that the Radeon 880M is roughly seven times faster in this Vulkan-based benchmark. This result underscores the modern API efficiency of the RDNA 3.5 architecture compared to the older Intel Generation 9.0 design.

Looking at the broader average benchmark scores, the AMD Radeon 880M posts an average of 8,436 points across its full benchmark suite, which includes DirectX 10, 11, 12, and 9 tests, plus G2D, G3D, GPU compute, Steel Nomad, OpenCL, and Vulkan results. The Intel Iris Pro Graphics P580, limited to only the two Geekbench tests in the database, averages 7,170 points. The nearest rival data places the AMD part at a 0.1% lead over the NVIDIA GeForce GTX 675MX and a 1.3% lead over the AMD Radeon R9 M375X, confirming that its performance sits in a competitive range among older discrete mobile graphics solutions. The Intel part, by contrast, sits essentially level with the NVIDIA GeForce GTX 560 SE (0% delta) and trails the NVIDIA GeForce GTX 750 by 0.7%.

Architecture Differences

The architectural gap between these two integrated GPUs is fundamental and spans process technology, design generation, and feature support. The AMD Radeon 880M is built on TSMC's 4 nm process node, while the Intel Iris Pro Graphics P580 uses Intel's 14 nm+ process. This process difference alone explains a significant portion of the performance gap, as the 4 nm node allows for higher transistor density and lower power consumption per operation. The AMD chip, codenamed Strix Point, packs 34,000 million transistors onto a 233 mm² die, yielding a transistor density of 145.9 million transistors per square millimeter. The Intel part's transistor count and die size are not recorded in the database, but the architectural generation difference is clear: the Radeon 880M belongs to the RDNA 3.5 family, while the Intel part uses Generation 9.0 based on the Skylake GT4e chip.

Shader configuration also diverges sharply. The AMD Radeon 880M contains 768 shading units, 48 texture mapping units, and 16 render output units. The Intel Iris Pro Graphics P580 has fewer shading units at 576, but a higher count of texture mapping units at 72, and only 9 render output units. The pixel rate figures reflect this imbalance: the AMD part delivers 46.40 GPixel/s, while the Intel part manages just 9.000 GPixel/s. Texture rate favors AMD as well, with 139.2 GTexel/s versus 72.00 GTexel/s for Intel. The floating-point throughput shows the largest gap on paper: the Radeon 880M achieves 4.454 TFLOPS in FP32, while the Intel part reaches only 1,152.0 GFLOPS (1.152 TFLOPS). In FP16, the AMD part maintains 4.454 TFLOPS with a 1:1 ratio, while Intel reaches 2.304 TFLOPS with a 2:1 ratio.

Clock speeds also differ significantly. The AMD Radeon 880M has a base clock of 400 MHz and a boost clock of 2,900 MHz, while the Intel Iris Pro Graphics P580 runs at a 350 MHz base and a 1,000 MHz boost. The AMD part's boost clock nearly triples the Intel part's, which directly contributes to its higher fill rates and compute throughput. Both parts feature system-shared memory with system-dependent bandwidth, so memory configuration is not a differentiating factor in the database.

The Radeon 880M adds dedicated ray tracing cores, with 12 listed in the specifications, while the Intel part has none recorded. This represents a major feature divergence, as ray tracing support is absent from the older Intel architecture entirely. The API support further separates the two: the AMD part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the Intel part supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The DirectX feature level difference means the AMD part can handle more advanced rendering features in modern titles, which pairs with its ray tracing capability.

The Verdict

The data points to a clear choice for anyone comparing these two integrated graphics solutions. The AMD Radeon 880M outperforms the Intel Iris Pro Graphics P580 in every recorded head-to-head benchmark, with margins ranging from 244.5% in OpenCL to 660.9% in Vulkan. The AMD part also holds a higher percentile rank among all GPUs, sitting at the 43rd percentile versus the Intel part's 39th percentile. The average benchmark score of 8,436 for the AMD part versus 7,170 for the Intel part further reinforces this ordering.

The Intel Iris Pro Graphics P580 is an end-of-life product released in 2015, while the AMD Radeon 880M is an active product released in 2024. The architectural advantages of the AMD part, including a newer process node, higher boost clock, more shading units, dedicated ray tracing cores, and more advanced DirectX and Vulkan support, all contribute to its superior measured performance. The Intel part's only specification advantages are a higher texture mapping unit count (72 versus 48) and a higher FP16 throughput ratio (2:1 versus 1:1), but these do not translate into any benchmark wins in the recorded data.

Where Each One Wins

The AMD Radeon 880M wins in all directly comparable workloads. In OpenCL compute, it delivers 244.5% higher scores, making it the clear choice for general-purpose GPU computing tasks that leverage OpenCL. In Vulkan graphics, its 660.9% lead indicates that modern Vulkan-based applications will run dramatically better on the AMD part. The AMD part's 4.454 TFLOPS FP32 throughput, 46.40 GPixel/s pixel rate, and 139.2 GTexel/s texture rate provide the raw horsepower for demanding graphics workloads and compute-heavy applications.

The Intel Iris Pro Graphics P580 does not have a single recorded benchmark win in this comparison. Its higher texture mapping unit count (72 versus 48) suggests it could theoretically handle texture-heavy workloads better per clock, but the AMD part's much higher boost clock (2,900 MHz versus 1,000 MHz) and overall texture rate (139.2 GTexel/s versus 72.00 GTexel/s) negate this advantage in practice. The Intel part's FP16 throughput of 2.304 TFLOPS at a 2:1 ratio is lower than the AMD part's 4.454 TFLOPS at a 1:1 ratio, so even half-precision workloads favor AMD.

For users seeking integrated graphics with modern feature support, ray tracing capability, and strong performance in both compute and graphics APIs, the AMD Radeon 880M is the only viable option based on the recorded data. The Intel Iris Pro Graphics P580 remains a legacy part whose performance profile is firmly in the past, suitable only for systems that require its specific motherboard-dependent display outputs and older API compatibility.
