Intel HD Graphics 615 Mobile

Intel HD Graphics 615 Mobile is an integrated graphics processor built on the Kaby Lake GT2 chip, utilizing Intel’s Generation 9.5 architecture. It is manufactured on a 14 nm++ process node and represents an end-of-life product. The GPU is positioned as a mobile solution, with its performance profile placing it at the 50th percentile among all GPUs in the database, although it carries no benchmark scores or average score metrics in the current dataset.

Power and Cooling

The Intel HD Graphics 615 Mobile operates with a thermal design power (TDP) of just 5 W. This ultra-low power envelope is characteristic of integrated graphics solutions, making the component suitable for fanless or passively cooled designs in thin-and-light portable devices. The slot width is listed as IGP, meaning it occupies no expansion slot and shares the motherboard layout directly.

There is no suggested power supply unit (PSU) recommendation in the fact pack, and no power connector requirements are specified. This is consistent with its integrated nature, as the GPU draws power from the system’s main power delivery rather than requiring a dedicated PCIe power connector. The absence of power connector data indicates that no external power cabling is needed for installation or operation.

Given the 5 W TDP, thermal management is a minimal concern for system designers. The heat generated is negligible compared to discrete graphics cards, allowing for compact cooling solutions. The production status is end-of-life, which may affect long-term availability but not the immediate power characteristics. The data shows no competitor comparisons for power efficiency, but the 5 W figure firmly places this part in the ultra-low-power segment.

Memory Subsystem

The memory subsystem of the Intel HD Graphics 615 Mobile is entirely dependent on the host system. The video memory size is listed as "System Shared," meaning it allocates from the main system RAM rather than having dedicated VRAM. The memory type is likewise "System Shared," and the bus width is reported as "System Shared," indicating that the memory interface is not a fixed physical bus but rather the system’s memory controller.

Memory bandwidth is described as "System Dependent," which is a critical distinction from discrete GPUs. The bandwidth available to the GPU will vary based on the system’s memory configuration, including the number of channels, memory speed, and whether dual-channel mode is enabled. For high-resolution workloads, this dependency is a significant limiting factor. The pixel rate is 2.550 GPixel/s and the texture rate is 20.40 GTexel/s, both of which are modest figures that reflect the shared memory architecture.

At high resolutions, such as 1440p or 4K, the system-shared memory becomes a bottleneck. The GPU must compete with the CPU for memory bandwidth, and the effective bandwidth available to the graphics workload can be substantially lower than what a dedicated VRAM solution would offer. Benchmark results indicate that this GPU is not designed for high-resolution gaming or compute tasks, as the memory subsystem cannot provide consistent throughput. The FP32 performance is 326.4 GFLOPS, with FP16 at 652.8 GFLOPS (2:1 ratio), but these compute rates are constrained by the shared memory bandwidth.

Ray Tracing and Feature Set

The Intel HD Graphics 615 Mobile does not include dedicated ray tracing cores or tensor cores, as indicated by the null values in the fact pack. This is expected for an integrated GPU from the Generation 9.5 architecture, which predates hardware-accelerated ray tracing in mainstream graphics. The absence of these specialized cores means that any ray tracing workloads would be handled through software or compute shaders, resulting in significantly reduced performance compared to hardware-accelerated implementations.

The API support is comprehensive for its generation. The GPU supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The DirectX 12_1 feature level includes support for conservative rasterization and other advanced rendering features, though the actual performance will be limited by the underlying hardware. The Vulkan 1.3 support provides access to modern low-overhead rendering APIs, which can improve efficiency in compatible applications.

The shading units total 192, with 24 texture mapping units (TMUs) and 3 raster output units (ROPs). The low ROP count of 3 is particularly limiting for pixel-heavy workloads, as it restricts the fill rate to 2.550 GPixel/s. The texture rate of 20.40 GTexel/s is similarly constrained. These specifications indicate that the GPU is intended for basic display output and light 2D/3D acceleration rather than demanding graphics features. The display outputs are listed as "Portable Device Dependent," meaning the available ports vary by the specific laptop or device implementation.

How It Compares

The fact pack lists no nearest rivals for the Intel HD Graphics 615 Mobile, and the benchmark array is empty. The percentile vs all GPUs is 50, which places it at the median of the database, but this is based on an average benchmark score of 0, suggesting that the percentile may reflect the absence of data rather than an actual performance ranking.

Without rival comparisons, the data cannot indicate how this GPU performs relative to other integrated or discrete solutions. The 50th percentile position is ambiguous; it could imply that this GPU sits in the middle of the performance distribution, but the lack of benchmark scores undermines any meaningful interpretation. The nearestRivals field is empty, so no direct performance deltas can be cited.

In the absence of rival data, the only quantitative comparisons available are the internal specifications. The 5 W TDP and system-shared memory architecture place this GPU firmly in the entry-level integrated segment. The FP32 performance of 326.4 GFLOPS is a hard number that could be compared to other parts if data were available, but no such comparisons are present in the fact pack. The production status of end-of-life suggests that this GPU represents an older generation, likely superseded by more capable integrated solutions.

Who Should Consider It

The Intel HD Graphics 615 Mobile is intended for basic portable computing tasks. Given the system-shared memory and 5 W TDP, it is suitable for office productivity, web browsing, and video playback. The DirectX 12 (12_1) and Vulkan 1.3 support allow for compatibility with modern applications, but the low shading unit count (192) and minimal ROPs (3) restrict gaming to very low resolutions and settings.

For users targeting 1080p gaming, the data indicates this GPU would struggle. The pixel rate of 2.550 GPixel/s and texture rate of 20.40 GTexel/s are insufficient for modern game engines at standard settings. The FP32 throughput of 326.4 GFLOPS is below what is typically required for smooth gameplay in AAA titles. Benchmark results do not exist to confirm actual frame rates, but the architectural limitations are clear.

The GPU is more appropriate for legacy titles, indie games, or 2D games at low resolutions. Users who prioritize battery life and silent operation over graphics performance might find the 5 W TDP appealing, as it enables fanless designs in ultraportable laptops. The end-of-life status suggests that new systems would not ship with this GPU, but existing devices could still serve for light productivity.

For high-resolution output, such as 4K video playback, the GPU can handle display output, but the system-dependent bandwidth may cause issues with high-bitrate content. The Vulkan 1.3 support is a positive for compatibility with modern compute workloads, but the performance ceiling is low. Overall, this GPU is best suited for users who need basic graphics acceleration in a power-efficient mobile form factor, with no expectation of high-end gaming or ray tracing.
