Intel UHD Graphics 615 Mobile

The Intel UHD Graphics 615 Mobile is an integrated graphics processor built on Intel's 14 nm process, using the Amber Lake GT2 chip and Generation 9.5 architecture. Released on November 6, 2018, and now marked as end-of-life, it is a low-power part with a 15 W TDP, designed for thin-and-light laptops. It features 192 shading units, 24 texture mapping units, and 3 raster output units, with base and boost clocks of 300 MHz and 900 MHz respectively. The GPU supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3, and relies on system-shared memory with bandwidth dependent on the host platform.

How It Compares

The database lists no nearest rivals for this GPU, and its benchmark array is empty. The only comparative metric available is a 50th percentile rank among all GPUs, placing it exactly at the median of the performance distribution. Without rival scores or delta percentages, no direct head-to-head comparisons can be made. This absence of data means that any assessment must rely on the raw specifications and theoretical throughput figures.

A 50th percentile rank suggests that the UHD Graphics 615 Mobile sits in the middle of the entire GPU landscape, which includes both discrete and integrated parts. However, given that the database covers a broad range of hardware, this rank does not necessarily indicate strong absolute performance. It does imply that half of all GPUs in the database are slower and half are faster, but the lack of specific rival scores prevents a more granular interpretation. The GPU's integrated nature and low TDP further suggest that it is not intended to compete with high-end discrete graphics cards, but rather to serve as a baseline for everyday computing.

Who Should Consider It

The specifications point to a GPU suited for basic productivity, media playback, and light 3D workloads. Its 192 shading units and 3 ROPs yield a pixel rate of 2.7 GPixel/s, while the 24 TMUs produce a texture rate of 21.6 GTexel/s. These figures are modest by modern standards, indicating that the GPU is not designed for high-resolution gaming or intensive rendering tasks. The FP32 performance of 345.6 GFLOPS further underscores its entry-level positioning, though the FP16 rate of 691.2 GFLOPS (2:1) shows that half-precision operations can be processed at double speed, which may benefit certain compute workloads.

Because the memory interface is system shared, the GPU's effective bandwidth is system dependent. Users with dual-channel high-speed memory may see better performance than those with single-channel configurations, but the database does not quantify this effect. The GPU supports DirectX 12 and Vulkan 1.3, so it can run applications that use these APIs, but its compute throughput suggests that only undemanding titles or older games would run smoothly. For users who prioritize power efficiency over graphics capability—such as those who need a laptop for office work, web browsing, and video streaming—this GPU is a suitable choice. Its 15 W TDP makes it appropriate for fanless or low-noise designs, though the database does not specify cooling solutions.

Power and Cooling

The UHD Graphics 615 Mobile has a TDP of 15 W, which is typical for an integrated GPU in a low-power mobile segment. No dedicated power connectors are listed, and no suggested PSU is provided, consistent with its integrated design. The GPU uses a Ring Bus interface to communicate with the rest of the system, a common interconnect for Intel integrated graphics. The 14 nm process node helps keep power consumption low, and the end-of-life status indicates that it has been superseded by newer parts.

The low TDP means that cooling requirements are minimal. In most implementations, the GPU shares the thermal solution with the CPU, and the absence of a separate power connector simplifies system integration. The database does not list a suggested PSU, which is expected for an IGP that draws power from the motherboard rather than a dedicated supply. The portable device dependent display outputs further emphasize that the GPU is designed for flexible integration into various laptop chassis, where the number and type of display connections vary by design.

Benchmark Performance

The database contains no benchmark scores for this GPU, and its average benchmark score is listed as 0. However, the percentile rank of 50 indicates that it falls exactly in the middle of the performance distribution of all GPUs in the database. Without specific scores or rival comparisons, we can only analyze its theoretical throughput. The pixel rate of 2.7 GPixel/s is derived from 3 ROPs operating at a boost clock of 900 MHz. The texture rate of 21.6 GTexel/s comes from 24 TMUs at the same clock. The FP32 performance of 345.6 GFLOPS is calculated from 192 shading units, while FP16 performance is 691.2 GFLOPS with a 2:1 ratio, meaning that half-precision operations are processed at twice the FP32 rate.

These figures place the GPU in the lower tier of the performance spectrum, but the 50th percentile rank suggests it is not the slowest part in the database. The lack of benchmark scores means we cannot quantify its real-world performance in applications or games. The theoretical rates indicate that the GPU is capable of handling basic 2D rendering and light 3D tasks, but it would likely struggle with modern 3D titles at high resolutions. The system-dependent memory bandwidth further complicates any performance prediction, as the actual throughput will vary with the host platform's memory configuration. Overall, the data suggests a GPU designed for power efficiency and basic functionality rather than for demanding graphics workloads.
