Intel Iris Pro Graphics P580

Intel Iris Pro Graphics P580 is an integrated graphics solution from Intel, built on the Skylake GT4e chip and fabricated on a 14 nm+ process. It is an end-of-life product that operates with system-shared memory, meaning its performance is heavily dependent on the host system's RAM and CPU. With an average benchmark score of 10,189 and a 48th percentile ranking among all GPUs, this iGPU sits squarely in the mid-range of the performance spectrum, making it a viable option for specific use cases rather than a general-purpose gaming powerhouse.

Who Should Consider It

The Intel Iris Pro Graphics P580 is best suited for users who primarily engage in light to medium-load productivity tasks and casual gaming at lower resolutions. Benchmark results indicate a Geekbench OpenCL score of 9,182 and a Vulkan score of 11,196, which place it in a territory where 1080p gaming is possible but only with reduced settings and older titles. For resolution-bound decisions, this GPU is not designed for 1440p or 4K gaming; the data suggests its compute capabilities are better aligned with 720p to 1080p workloads where texture detail and shadow quality are set to low or medium.

Users who prioritize power efficiency and have no need for a discrete graphics card will find this iGPU attractive, given its 15 W TDP. It is ideal for compact builds, office machines, or media centers where space and thermal output are constraints. However, for those expecting to play modern AAA titles at high settings, the scores indicate this is not the appropriate choice. The P580’s performance is comparable to entry-level discrete GPUs, so it can handle esports titles like older MOBAs or CS:GO-style shooters, but frame rates will be inconsistent in more demanding scenarios. The system-shared memory architecture means performance will scale with the speed and amount of system RAM; faster dual-channel memory will yield better results than single-channel configurations.

Ray Tracing and Feature Set

The Intel Iris Pro Graphics P580 does not include dedicated ray tracing cores or tensor cores, as these hardware units are absent from the specification data. This is a Generation 9.0 architecture part, which predates the hardware-level ray tracing acceleration found in newer discrete GPUs. Consequently, any ray-traced effects in games would have to be handled through software or compute shaders, which would severely impact frame rates given the available 1,152.0 GFLOPS of FP32 performance.

In terms of API support, the GPU is compliant with DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. This feature set ensures broad compatibility with modern game engines and applications that rely on these APIs. The absence of tensor cores also means that AI-accelerated workloads like DLSS are not supported, but the Vulkan 1.3 support allows for access to modern rendering techniques and optimizations that can partially mitigate the lack of dedicated hardware. For productivity, the FP16 performance of 2.304 TFLOPS (2:1) is notably higher than FP32, which can benefit certain compute workloads that utilize half-precision arithmetic, though this is a niche advantage in gaming contexts.

Benchmark Performance

The benchmark data reveals a tightly clustered performance group, with the Intel Iris Pro Graphics P580 posting an average score of 10,189. This places it marginally behind the NVIDIA GeForce GTX 950A, which scores 10,220, representing a negligible delta of -0.3%. In practical terms, this difference is within run-to-run variance, meaning the two GPUs are effectively tied in raw compute throughput.

Against the NVIDIA Quadro P4000, the P580 trails by a mere 0.5%, with the Quadro scoring 10,134. This is a surprising result given the Quadro P4000’s professional positioning, but the data shows they are nearly identical in these synthetic benchmarks. The AMD Radeon RX 550X edges ahead with a score of 10,095, a 0.9% advantage over the Intel part. Again, this is a marginal difference that would not be perceptible in real-world usage.

The largest gap in this group is against the AMD Radeon R9 M375, where the P580 is 1.9% behind, with the R9 M375 scoring 10,001. The overall picture is one of extreme parity among these four GPUs; the P580 is not dramatically faster or slower than any of them. The Vulkan score of 11,196 is notably higher than the OpenCL score, suggesting that the architecture responds well to modern, low-overhead APIs, which could translate to better performance in Vulkan-based games compared to older DirectX 11 titles.

How It Compares

NVIDIA GeForce GTX 950A: The P580 is effectively on par with the GTX 950A, with a performance delta of just -0.3%. In gaming scenarios, the two should deliver nearly identical frame rates, meaning the choice between them comes down to system-level factors like driver support and power consumption, rather than raw speed.

NVIDIA Quadro P4000: The Quadro P4000 is only 0.5% faster than the P580 in average benchmark scores. This is a notable finding because the Quadro is a professional workstation card with higher VRAM and certification, yet the synthetic compute scores show the Intel iGPU holding its own. For users who do not need professional driver optimizations, the P580 offers comparable compute performance at a fraction of the system complexity.

AMD Radeon RX 550X: The RX 550X is 0.9% ahead of the P580. This discrete GPU has the advantage of dedicated memory, which should provide more consistent performance in memory-bandwidth-sensitive tasks, but the benchmark scores do not reflect a significant superiority. The P580’s system-shared memory can be a bottleneck, but the compute results suggest it is well-optimized within its constraints.

AMD Radeon R9 M375: The R9 M375 leads the P580 by 1.9%, the largest gap in the comparison group. Even so, this delta is small enough to be considered negligible in most applications. The R9 M375 is an older mobile GPU, and the fact that the P580 competes with it demonstrates that Intel’s integrated solution has matured significantly in this generation.

Power and Cooling

The Intel Iris Pro Graphics P580 has a maximum thermal design power (TDP) of 15 W, which is exceptionally low and typical for an integrated graphics processor. This low power draw means that no dedicated power connectors are required, as the specification lists no power connector requirements. The slot width is designated as IGP, indicating it is integrated into the motherboard or CPU package rather than being a separate card.

Because of the minimal power requirements, the suggested PSU is not listed in the data, but it is safe to assume that any standard power supply capable of running the host CPU will be more than sufficient. The cooling solution is likewise motherboard-dependent, and the low TDP means that a basic heatsink or even passive cooling solutions can adequately handle the thermal output. This makes the P580 an excellent choice for ultra-portable laptops or compact desktops where space and cooling are at a premium. The bus interface is a Ring Bus, which is an internal interconnect rather than a PCIe slot, further confirming its integrated nature. Display outputs are also motherboard-dependent, so the available ports will vary based on the specific motherboard or laptop design.
