Intel Iris Pro Graphics 6200 vs Intel Iris Pro Graphics P580 Comparison

Head-to-Head Benchmarks

The benchmark data shows two distinct performance profiles for these integrated graphics processors. In the Geekbench OpenCL test, the Intel Iris Pro Graphics P580 posts a score of 9,082, while the Intel Iris Pro Graphics 6200 manages 4,556. That is a 99.3% advantage for the P580, meaning it delivers nearly double the compute throughput in this workload. The margin is substantial enough that the P580 sits in the 39th percentile of all GPUs in the database, while the 6200 lands in the 35th percentile. The average benchmark score across all recorded tests reinforces the gap: the P580 averages 7,170, and the 6200 averages 6,117.

The Vulkan results flip the narrative. Here, the Iris Pro Graphics 6200 scores 6,032, beating the P580's 5,258 by 12.8%. This is a meaningful reversal, as it suggests the older Broadwell-based part has an advantage in this particular API workload. The P580 still holds a higher average score overall, but the Vulkan result shows that the 6200 is not simply outclassed in every scenario.

Looking at the nearest rivals in the database, the P580's OpenCL score of 9,082 aligns it with discrete mobile and desktop parts. The NVIDIA GeForce GTX 560 SE averages 7,171, which is essentially identical to the P580's average of 7,170, a delta of 0%. The NVIDIA GeForce GTX 970 averages 7,157, just 0.2% behind. The AMD Radeon Vega 8 Mobile averages 7,203, 0.5% ahead, and the NVIDIA GeForce GTX 750 averages 7,222, 0.7% ahead. These tight margins indicate that the P580's integrated design competes with entry-level discrete GPUs in aggregate performance.

For the 6200, its average of 6,117 places it near the AMD Radeon HD 8690M, which averages 6,137, a delta of 0.3% in favor of the AMD part. The NVIDIA RTX A400 averages 6,078, 0.6% behind the 6200, and the NVIDIA GeForce MX230 averages 6,077, 0.7% behind. The NVIDIA Quadro P2000 averages 6,049, 1.1% behind. These comparisons show the 6200 sitting in a lower performance tier than the P580, closer to older or lower-end discrete solutions.

Where Each One Wins

The P580 wins the compute-heavy OpenCL test decisively. With 576 shading units, 72 texture mapping units, and 9 ROPs, it has a hardware resource advantage that translates directly into a 99.3% lead in this workload. The fp32 output of 1,152.0 GFLOPS is substantially higher than the 6200's 844.8 GFLOPS, and the pixel rate of 9.000 GPixel/s versus 6.600 GPixel/s further underscores the P580's rendering throughput advantage. The texture rate of 72.00 GTexel/s versus 52.80 GTexel/s follows the same pattern.

The 6200 wins the Vulkan test, and the margin is notable at 12.8%. This is despite having fewer shading units (384 versus 576), fewer TMUs (48 versus 72), and fewer ROPs (6 versus 9). The 6200 also has a lower base clock of 300 MHz versus 350 MHz, though its boost clock of 1100 MHz is higher than the P580's 1000 MHz. The Vulkan advantage may stem from driver maturity or architectural differences in how the Generation 8.0 design handles this API, but the recorded data does not provide further detail. What is clear is that the 6200 is not universally slower, and in Vulkan-specific scenarios it pulls ahead.

For users prioritizing OpenCL compute tasks, the P580 is the clear choice. For Vulkan-based workloads, the 6200 holds an edge. The aggregate benchmark average favors the P580, but the split is exactly even at one win each across the two head-to-head tests.

Architecture Differences

The two GPUs come from different Intel generations. The P580 is based on the Skylake GT4e chip, which uses the Generation 9.0 architecture and is built on a 14 nm+ process node. The 6200 uses the Broadwell GT3e chip with the Generation 8.0 architecture on a standard 14 nm node. The process refinement for Skylake is the only node difference; both use Intel as the foundry.

The execution resources differ substantially. The P580 has 576 shading units, 72 TMUs, and 9 ROPs. The 6200 has 384 shading units, 48 TMUs, and 6 ROPs. This is a 50% increase in shader count and TMU count for the P580, and a 50% increase in ROPs as well. Clock speeds are close: the P580 runs at 350 MHz base and 1000 MHz boost, while the 6200 runs at 300 MHz base and 1100 MHz boost. The higher boost clock on the 6200 does not compensate for its smaller execution engine.

Memory is handled identically in both designs: system shared memory with a system shared bus width, and bandwidth described as system dependent. Both use a Ring Bus interface and have a TDP of 15 W. Both are IGP slot width parts with motherboard-dependent display outputs.

API support differs. The P580 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The 6200 supports DirectX 12 (11_1), OpenGL 4.4, and Vulkan 1.0. The newer architecture on the P580 provides a higher feature level for DirectX and a newer OpenGL and Vulkan version. The 6200 has no recorded fp16 performance data, while the P580 lists 2.304 TFLOPS (2:1) for fp16.

The release dates are about a year apart: the 6200 launched on September 4, 2014, and the P580 launched on August 31, 2015. Both are end-of-life products with no recorded launch MSRP.
