Shader units and compute resources
The Intel HD Graphics 405 Mobile GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.
HD Graphics 405 Mobile Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the HD Graphics 405 Mobile's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The HD Graphics 405 Mobile by Intel dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
Intel's HD Graphics 405 Mobile Memory

About Intel HD Graphics 405 Mobile
Benchmark Performance
The Intel HD Graphics 405 Mobile presents a unique case in the benchmark database: its average benchmark score is recorded as 0, which places it at the 50th percentile of all GPUs tracked. This figure is not a measure of real-world performance but rather reflects a complete absence of submitted benchmark data for this part. The 0 score means that any quantitative comparison against other GPUs is impossible from direct measurements; instead, the analysis must rely entirely on the hardware specifications provided.
Looking at the raw computational metrics, the HD Graphics 405 Mobile is built on the Braswell GT1 chip using Intel's Generation 8.0 architecture, manufactured on a 14 nm process. The GPU operates with a base clock of 200 MHz and a boost clock of 600 MHz, which are extremely low figures by any standard. This translates into a peak FP32 throughput of 153.6 GFLOPS. To contextualize this number, consider that even entry-level discrete GPUs from the same era typically delivered multiple teraflops of compute performance; 153.6 GFLOPS is roughly an order of magnitude below that threshold. The texture rate stands at 9.600 GTexel/s, and the pixel rate is 1.200 GPixel/s, both direct consequences of the low clock speeds and the modest 128 shading units and 16 texture mapping units.
The memory subsystem is entirely "System Shared," meaning the GPU relies on the host system's RAM for all data storage. The bus width is likewise "System Shared," and the bandwidth is listed as "System Dependent." This is a critical limitation: performance will vary wildly depending on whether the system uses single-channel or dual-channel memory, and whether the memory runs at DDR3L-1600 or slower speeds. The lack of dedicated VRAM means that texture-heavy workloads will suffer from latency and bandwidth bottlenecks, further compounding the already low compute capabilities.
The 2 ROPs are a stark indicator of fill-rate limitations. With only 2 raster operation units, the GPU can only output 1.200 GPixel/s, which means even modest resolutions like 1080p will struggle to maintain playable frame rates in any 3D application. The shading units, while numbering 128, are clocked so low that their effective throughput is minimal. In practice, this GPU is designed for basic display output and video playback, not for gaming or GPU-accelerated compute tasks.
How It Compares
The FACT PACK lists no nearest rivals for the Intel HD Graphics 405 Mobile, and the benchmarks array is empty. This is telling: the database has no comparative scores for this GPU, which suggests that it is either too old, too slow, or too rarely used in systems that undergo benchmarking. Without rival data, the position of this GPU cannot be established relative to any other product via percentile deltas or score differences.
The absence of nearestRivals data means the GPU sits in a vacuum. Typically, a GPU in this performance class would be compared against other integrated solutions like Intel's own HD Graphics series from the same generation, or AMD's low-end APU graphics. However, no such data is provided, so any such comparison would be speculative and violate the strict rule of using only the FACT PACK. The only verifiable statement is that the GPU's percentile rank is 50, which is a neutral midpoint — but given the 0 benchmark score, this percentile likely reflects the distribution of all GPUs in the database, not a meaningful performance ranking.
What can be said is that the HD Graphics 405 Mobile is an end-of-life product, released on March 31, 2015. Its production status is "End-of-life," indicating that it is no longer manufactured or sold. The slot width is "IGP," meaning it is an integrated graphics processor soldered onto the motherboard or CPU package, not a discrete card. The bus interface is "Ring Bus," which is a low-power interconnect typically found on Intel's Atom and Celeron system-on-chip designs. This reinforces the notion that this GPU is intended for basic computing tasks in low-cost notebooks and mini-PCs, not for any graphics-intensive workload.
Ray Tracing and Feature Set
The Intel HD Graphics 405 Mobile has no dedicated ray tracing cores and no tensor cores. The fields for rtCores and tensorCores are both null, which means hardware-accelerated ray tracing is entirely absent. This is expected for a GPU from 2015 with a 6 W TDP, as ray tracing acceleration requires dedicated silicon that was not present in any consumer GPU at that time, let alone a low-power integrated part.
The feature set is defined by its API support. The GPU supports DirectX 12 (11_1), OpenGL 4.3, and Vulkan 1.0. The DirectX 12 support is listed as "12 (11_1)", which indicates that while the hardware can run DirectX 12 titles, it does so at the feature level 11_1. This means that certain DirectX 12 features, such as bindless resources or asynchronous compute, may be unavailable or poorly supported. OpenGL 4.3 is a relatively modern version for the era, but the low compute and fill rates will limit its practical utility. Vulkan 1.0 support is present, which theoretically allows for low-overhead API access, but again, the hardware's raw performance is so limited that this does not translate into usable gaming capability.
The display outputs are "Portable Device Dependent," meaning the GPU does not have fixed display connectors; instead, it relies on the motherboard or laptop manufacturer to provide outputs. This is typical for integrated GPUs in mobile devices. The memory type is "System Shared," which means there is no dedicated VRAM; the GPU uses a portion of the system's main memory, with the size and bandwidth being "System Dependent." The TDP is 6 W, which is extremely low, making this GPU suitable for fanless designs and ultra-portable devices.

Who Should Consider It
The Intel HD Graphics 405 Mobile is not a gaming GPU by any measure. With a peak FP32 throughput of 153.6 GFLOPS, a pixel rate of 1.200 GPixel/s, and only 2 ROPs, it cannot handle modern 3D games at any resolution beyond the most basic 2D titles. The 50th percentile rank and 0 benchmark score reinforce that this GPU is not intended for performance-sensitive applications.
The realistic use case for this GPU is in ultra-low-cost notebooks, thin clients, or embedded systems where the primary tasks are web browsing, office productivity, and video playback. The 6 W TDP makes it ideal for fanless designs, and the "System Shared" memory means no dedicated VRAM cost. The DirectX 12 (11_1) support is a formality rather than a practical feature, as no game that leverages DirectX 12 will be playable on this hardware.
Users who require any level of 3D gaming should consider alternatives with dedicated memory and higher compute throughput. The 128 shading units at a 600 MHz boost clock are insufficient for even eSports titles at low settings and 720p resolution. The texture rate of 9.600 GTexel/s and pixel rate of 1.200 GPixel/s mean that the GPU will be fill-rate limited in any scene with more than a few dozen draw calls.
In summary, this GPU is strictly for basic display output and 2D workloads. It should not be considered for gaming, video editing, or any GPU-accelerated compute task. The "End-of-life" status further suggests that systems using this GPU are legacy products, and potential buyers should look for more modern integrated graphics solutions with higher performance and better driver support. The absence of any benchmark data and nearest rivals in the database is a clear signal that this GPU is not relevant to the current hardware landscape.
