Intel Iris Pro Graphics P580 Mobile

The Intel Iris Pro Graphics P580 Mobile is an integrated graphics processor built on Intel's Skylake GT4e chip, fabricated on a 14 nm+ process. It operates at a base clock of 350 MHz with a boost clock of 1050 MHz, and its memory interface is entirely system-shared, meaning the VRAM size, type, bus width, and bandwidth are all dependent on the host system's RAM configuration. The part carries a TDP of 15 W, is classified as an IGP with a Ring Bus interface, and its display outputs are portable-device dependent. As of its release date of August 31, 2015, it is now marked as end-of-life in production status. The benchmark database lists no direct benchmark scores for this GPU, and its average benchmark score is 0, while its percentile ranking against all GPUs stands at exactly 50.

How It Compares

The nearestRivals field for the Iris Pro P580 Mobile is empty, so a direct comparison against specific competing parts is not available from the dataset. Instead, the percentile ranking provides the only positional reference: this GPU sits at the 50th percentile among all GPUs tracked by the database. That midpoint placement suggests it is neither a standout performer nor a bottom-tier part, but rather an average integrated solution. Without rival names or delta percentages, any head-to-head analysis must rely on the theoretical throughput figures and architectural traits. The lack of rival data also means that the relative performance claims often seen in other entries cannot be reproduced here; the analysis must remain grounded in the absolute specifications and the single percentile figure.

Given that the product is an integrated part with a 15 W TDP, its placement at the 50th percentile is plausible for a mobile iGPU from the mid-2010s. The absence of dedicated VRAM and the reliance on system memory further reinforces its position as a mainstream, power-efficient component rather than a performance-oriented one. The data does not indicate any competitor that it outperforms or trails, so the only conclusion is that it occupies a middle ground in the overall GPU landscape.

Ray Tracing and Feature Set

The Iris Pro P580 Mobile has no dedicated ray tracing cores and no tensor cores, as those fields are null in the specification. This is consistent with its architecture generation, Generation 9.0, which predates the dedicated hardware-accelerated ray tracing and tensor processing units found in later discrete GPUs. For API support, the part lists DirectX 12 (feature level 12_1), OpenGL 4.6, and Vulkan 1.3. These are modern API versions that allow the GPU to execute contemporary graphics workloads, though without RT or tensor hardware, any ray tracing or machine-learning tasks would have to rely on software fallbacks or compute shaders. The presence of Vulkan 1.3 support is notable for a 2015-era integrated part, as it enables cross-platform low-overhead rendering. The DirectX 12_1 feature level includes support for conservative rasterization and other advanced rasterizer features, which can improve geometry processing efficiency in supported titles. Overall, the feature set is typical for its generation, no dedicated acceleration for ray tracing or AI, but full compatibility with the then-current graphics APIs.

Benchmark Performance

The dataset provides no benchmark scores for the Iris Pro P580 Mobile, and the average benchmark score is explicitly 0. This means there is no measured performance data to analyze. However, the theoretical throughput figures offer a basis for understanding its computational capacity. The pixel fill rate is 9.450 GPixel/s, derived from 9 ROPs and the boost clock. The texture fill rate is 75.60 GTexel/s, coming from 72 TMUs. The single-precision floating-point performance (FP32) is 1,209.6 GFLOPS, and the half-precision (FP16) performance is 2.419 TFLOPS at a 2:1 ratio. These numbers indicate a modest compute capability, suitable for light gaming at low resolutions and basic productivity tasks. The FP16 throughput being exactly double the FP32 rate suggests that the architecture supports packed math operations, which can be beneficial for certain compute workloads that tolerate reduced precision. Without benchmark scores, it is impossible to state how these theoretical rates translate into real-world frame rates or application performance. The 50th percentile ranking is the only performance-related metric, but it is a relative ranking, not an absolute score. The absence of benchmark data means that any claims about actual speed must be tempered; the theoretical numbers are the only concrete performance indicators available.

Who Should Consider It

Given its integrated nature and 15 W TDP, the Iris Pro P580 Mobile is clearly aimed at portable devices, its display outputs are portable-device dependent, and the slot width is IGP. Users who would consider this GPU are those who prioritize battery life and low heat generation over raw graphics performance. The 576 shading units and 72 texture mapping units are modest, and the pixel rate of 9.450 GPixel/s suggests that it can handle 1080p output for desktop use and light media playback, but it would struggle with demanding 3D games at high settings. For resolution-specific guidance, the data does not include any resolution benchmarks, so we cannot directly recommend specific resolutions or settings. However, the FP32 throughput of 1,209.6 GFLOPS is roughly an order of magnitude below what discrete mid-range GPUs of the same era offered, implying that it is best suited for 720p or 1080p with reduced detail levels in older or less demanding titles. Users who need to run modern AAA games at high frame rates would not find this part adequate. Instead, it fits the profile of an office productivity laptop, a thin-and-light ultrabook, or a media consumption device where graphics acceleration is secondary to CPU performance and energy efficiency. The 50th percentile ranking among all GPUs suggests that it is an average performer for its time, which aligns with its intended market segment.

Memory Subsystem

The memory subsystem of the Iris Pro P580 Mobile is entirely system-shared. The memory size, type, bus width, and bandwidth are all listed as "System Shared" or "System Dependent." This means the GPU does not have its own dedicated VRAM; instead, it relies on the system's main memory (typically DDR3 or DDR4 in laptops of that era) for frame buffer and texture storage. The bandwidth is explicitly "System Dependent," so the effective memory performance will vary based on the host system's memory speed, channel configuration, and whether the memory is dual-channel. This architecture is common for integrated GPUs, but it also introduces a performance bottleneck: the GPU must compete with the CPU for memory bandwidth, and the shared memory bus can limit texture fetch rates and pixel throughput in memory-intensive scenes. The pixel rate of 9.450 GPixel/s and texture rate of 75.60 GTexel/s are theoretical maxima that assume sufficient memory bandwidth; in practice, the system-dependent nature of the memory means those figures may not be fully achieved. For high-resolution gaming or large texture sets, the shared memory interface would likely become a limiting factor, as the system RAM bandwidth is typically far lower than that of dedicated GDDR5 or GDDR6. Users should expect that performance at 1440p or 4K will be constrained not only by the GPU's compute capabilities but also by the available system memory bandwidth, which is not specified in the dataset.

Power and Cooling

The Iris Pro P580 Mobile has a TDP of 15 W, which is extremely low for a graphics processor, reflecting its integrated design. The slot width is listed as "IGP," meaning it is not a discrete card but a chip integrated into the motherboard or CPU package. As such, it requires no dedicated power connectors, the powerConnectors field is null, and there is no suggested PSU recommendation, because the GPU draws power from the system's existing power delivery circuitry. The cooling solution is likewise not specified, but given the low TDP, a passive heatsink or the laptop's existing thermal solution is likely sufficient. The 14 nm+ process helps keep power consumption in check, and the 15 W TDP includes the entire GPU die, not just the graphics execution units. For a mobile device, this low power draw is advantageous for battery life and thermals, but it also caps the achievable clock speeds and performance. The base clock of 350 MHz and boost clock of 1050 MHz are modest, and the lack of a dedicated power connector means there is no external power headroom for overclocking. In practice, the GPU's power envelope is tightly coupled to the system's thermal design, and sustained boost clocks may be limited in thin chassis. The absence of a suggested PSU is consistent with its integrated nature, it does not need a separate power supply unit, and the host system's power adapter is designed to handle the total system load.
