Intel HD Graphics 505 Mobile

The Intel HD Graphics 505 Mobile is an integrated graphics processor built on Intel's 14 nm process, using the Apollo Lake GT1.5 chip and the Generation 9.0 architecture. It is classified as an IGP with a Ring Bus interface, and it has been marked as end-of-life since its release on 2016-08-31. The part is positioned at the 50th percentile among all GPUs in the database, indicating a median performance standing, though its average benchmark score is recorded as 0, meaning no synthetic or real-world benchmarks are available in the dataset. This analysis relies solely on the technical specifications provided, interpreting what those figures imply for power, features, memory, and theoretical performance.

Power and Cooling

The HD Graphics 505 Mobile carries a thermal design power (TDP) of just 6 W. This extremely low power envelope is characteristic of an integrated solution designed for compact, fanless, or passively cooled systems, where thermal dissipation is a primary constraint. The slot width is listed as "IGP," confirming that it is not a discrete add-in card but rather a GPU integrated into the host processor or chipset. Consequently, the product has no dedicated power connectors; the `powerConnectors` field is null. There is also no suggested PSU recommendation, which is expected because the GPU draws all its power from the motherboard's standard power delivery, and the overall system PSU requirement is determined by the CPU and other components, not this GPU.

The base clock is 200 MHz, with a boost clock of 650 MHz. This wide frequency range suggests aggressive power gating and dynamic clock scaling, allowing the GPU to idle at very low power and only ramp up to 650 MHz under load. The 6 W TDP is the maximum sustained power draw, and in practice, the average consumption will be far lower during typical use. For cooling, the GPU relies on the system's existing thermal solution—whether that is a small heatsink, a heatpipe, or the chassis airflow. No additional cooling hardware is required beyond what is already present in the host device. The absence of a suggested PSU also reflects that this is a mobile or embedded part, often found in laptops, mini-PCs, or tablets, where the power supply is integrated into the device and not user-replaceable.

Ray Tracing and Feature Set

The HD Graphics 505 Mobile does not include dedicated ray tracing (RT) cores or tensor cores; both fields are null. This means that any ray-traced effects must be handled through compute shaders or other software-based approaches, which is typical for an integrated GPU of this generation. However, the API support is surprisingly modern for a 2016 product. It supports DirectX 12 with a feature level of 12_1, which includes features such as conservative rasterization, rasterizer-ordered views, and higher-order tessellation. OpenGL 4.6 is also supported, providing compatibility with a wide range of desktop and professional applications. Vulkan 1.3 is listed, which is a recent version of the low-overhead graphics API, enabling efficient multi-threaded rendering and explicit control over GPU resources.

The presence of these APIs does not imply high performance, but it does mean that the hardware is capable of running modern graphics workloads, albeit at low resolutions and detail settings. The lack of RT and tensor cores limits the GPU's ability to accelerate ray tracing or AI-based features such as DLSS, but those technologies were not mainstream at the time of its release. The shading units count 144, with 18 texture mapping units (TMUs) and 3 raster operation units (ROPs). These counts are modest, and the pixel rate is 1.950 GPixel/s, while the texture rate is 11.70 GTexel/s. The FP32 compute throughput is 187.2 GFLOPS. These numbers indicate a part that is designed for basic 2D acceleration, video playback, and light 3D workloads, not for high-end gaming or compute tasks.

Memory Subsystem

The memory configuration is entirely system-shared. The GPU uses the host system's main memory for both frame buffer and texture storage, with no dedicated VRAM. The memory type is listed as "System Shared," the bus width is "System Shared," and the bandwidth is "System Dependent." This means that the effective memory bandwidth available to the GPU is determined by the host system's memory controller, the number of memory channels, and the memory speed (e.g., DDR3L or LPDDR4). In a typical laptop or mini-PC, this might be a single-channel configuration, which would provide a fraction of the bandwidth available on discrete GPUs with dedicated GDDR memory.

The lack of dedicated VRAM has several implications. First, the GPU and CPU share the same memory pool, so heavy graphics workloads can compete with system memory for bandwidth, leading to performance degradation. Second, the memory bus width is not fixed; it depends on the host CPU's memory interface. The HD Graphics 505 is paired with Apollo Lake processors, which typically support dual-channel memory, but the actual configuration varies by system. Third, the "System Dependent" bandwidth means that performance can vary significantly from one device to another, even with the same GPU. For high resolutions, such as 1440p or 4K, the shared memory and limited bandwidth become a bottleneck, as the GPU must fetch and write large amounts of data over the same bus that the CPU uses. This is especially problematic for texture-heavy scenes or high-detail settings, where the GPU's limited ROP count (3) and low pixel rate will also constrain fill-rate performance.

How It Compares

The dataset provides no nearest rivals for the Intel HD Graphics 505 Mobile; the `nearestRivals` array is empty. Consequently, a direct head-to-head comparison against specific competing GPUs is not possible from the available facts. The only comparative metric is the percentile field, which lists a value of 50. This indicates that, within the database's tracked GPUs, this part sits at the exact median—meaning it outperforms 50% of all GPUs and is outperformed by the other 50%. This is a broad, database-level ranking, not a comparison to a particular competitor. Without rival names or scores, we cannot state specific deltas or percentages relative to other products.

Given the lack of rival data, the comparison must be contextualized through the GPU's own specifications. The 6 W TDP, 144 shading units, and 187.2 GFLOPS FP32 throughput place it firmly in the entry-level integrated segment. It is likely to be slower than most discrete GPUs from the same era, but it may be competitive with other low-power integrated solutions from Intel or AMD. However, without explicit rival data, any such statement would be speculative. The percentile of 50 suggests that the database contains a wide range of GPUs, including many high-end discrete parts, and that this integrated GPU is not at the bottom but rather in the middle, which is plausible given that the database may include many older or equally weak integrated parts. The absence of an average benchmark score (0) further limits quantitative comparison, so the analysis must rely on the theoretical rates described earlier.

Benchmark Performance

The `avgBenchmarkScore` for the Intel HD Graphics 505 Mobile is 0, meaning no benchmark results are recorded in the dataset. Therefore, we cannot provide any measured performance scores or deltas. However, we can analyze the theoretical throughput values that are given: pixel rate of 1.950 GPixel/s, texture rate of 11.70 GTexel/s, and FP32 compute of 187.2 GFLOPS. These numbers represent the maximum achievable rates under ideal conditions, assuming no bottlenecks from memory bandwidth or driver overhead.

The pixel rate of 1.950 GPixel/s means that the GPU can fill approximately 1.95 billion pixels per second. At a typical 1080p resolution (1920×1080 ≈ 2.07 million pixels), this would allow a fill rate of roughly 940 frames per second if the GPU were purely pixel-limited, but in practice, other factors such as geometry, texturing, and memory bandwidth will dominate. The texture rate of 11.70 GTexel/s indicates the speed at which texture samples can be fetched and filtered; this is a modest figure, suggesting that complex textures or high anisotropic filtering will quickly become a bottleneck. The FP32 throughput of 187.2 GFLOPS is the raw compute capability for single-precision floating-point operations. This is low compared to even entry-level discrete GPUs from the same period, but it is sufficient for basic shader effects, video processing, and light compute workloads.

The clock speeds (200 MHz base, 650 MHz boost) combined with 144 shading units yield the FP32 figure. The shading units are likely organized as 18 execution units (each containing 8 ALUs), which matches the 144 count. The TMU count of 18 and ROP count of 3 are also consistent with a very small GPU. The ROP count of 3 is particularly low, which limits the pixel fill rate and makes the GPU unsuitable for high-resolution or high-refresh-rate displays. The texture rate is derived from the TMUs and clock speed: 18 TMUs × 650 MHz = 11.7 GTexel/s, exactly matching the given value. Similarly, the pixel rate is 3 ROPs × 650 MHz = 1.95 GPixel/s. These calculations confirm that the listed rates are peak theoretical values at the boost clock.

In the absence of measured benchmarks, the theoretical rates provide the only quantitative insight. They indicate that the HD Graphics 505 Mobile is capable of basic 2D desktop rendering, hardware-accelerated video decode, and very light 3D applications such as older games at low resolutions and detail settings. For modern titles or any workload requiring high fill rates or compute throughput, the GPU will fall far short. The 50th percentile ranking, while not a direct performance measure, suggests that the database includes many GPUs that are equally limited, so the part is not an outlier at the bottom. Overall, the data paints a picture of a low-power, integrated graphics solution that is best suited for productivity and media consumption, not for gaming or professional graphics work.
