What Is an Integrated CPU GPU?
An integrated CPU GPU, also known as an APU (Accelerated Processing Unit) or a processor with on-chip graphics, combines the central processing unit (CPU) and graphics processing unit (GPU) into a single chip package. This design eliminates the need for a separate discrete graphics card, reducing power consumption, heat output, and physical footprint. For industrial computers and mini PCs, integrated graphics are ideal for applications that require visual output—such as digital signage, HMI (Human-Machine Interface) panels, and light video playback—without the cost or complexity of dedicated graphics hardware.
Key Specifications and Technical Details
Modern integrated GPUs are built directly into the processor die and share system memory (RAM) for graphics operations. Performance varies by processor family:
-
Intel® Processors (N-series, Core i3/i5): Feature Intel UHD Graphics or Intel Iris Xe Graphics. For example, the Intel N100 includes Intel UHD Graphics with up to 24 execution units (EUs), supporting 4K displays at 60 Hz. Core i3-1215U and i5-1240P integrate Intel UHD Graphics with higher clock speeds (up to 1.1 GHz) for smoother multitasking and video decoding.
-
ARM® Cortex Processors: Include Mali or Adreno GPUs optimized for low-power embedded Linux environments. The ARM Cortex A53 and A55 in Thinvent’s Micro series support 2D/3D acceleration and hardware video decoding up to 1080p.
Key considerations include:
-
Memory bandwidth: Integrated GPUs rely on system RAM; dual-channel DDR4/DDR5 improves graphics performance.
-
Display outputs: Common interfaces include HDMI 2.0, DisplayPort, and eDP for industrial monitors.
-
Thermal design: Fanless cooling is typical for mini PCs with integrated GPUs, ensuring silent operation in dust-prone environments.
Use Cases and Applications
Integrated CPU GPU systems excel in scenarios where space, power efficiency, and reliability are critical:
-
Digital Signage: Drive 4K displays for advertising boards or information kiosks without a discrete GPU.
-
HMI/SCADA: Operate touchscreen interfaces in factory automation, requiring smooth rendering of graphics and real-time data.
-
Point of Sale (POS): Retail terminals need basic graphics for transaction screens and barcode scanning.
-
Thin Client / VDI: Access virtual desktops with hardware-accelerated video decoding for remote work.
-
Edge Computing: Process video analytics from IP cameras (e.g., using Intel Quick Sync Video) for security or retail analytics.
Comparison: Integrated vs. Discrete GPU in Industrial PCs
| Feature | Integrated CPU GPU | Discrete GPU (e.g., NVIDIA/AMD) |
|---|---|---|
| Power Consumption | 6–28W typical (fanless designs) | 50–200W+ (requires active cooling) |
| Physical Size | No extra slot needed | Requires PCIe slot + space |
| Use Cases | Light graphics, 2D/3D, multi-display | Heavy 3D rendering, AI training, gaming |
| Cost | Included in processor cost | Adds $100–$500+ |
