TechPowerUp GPU-Z for Windows PC — Official Graphics Card Diagnostic & Sensor Monitor
TechPowerUp GPU-Z is the premier, industry-standard graphics subsystem diagnostic, video memory profiling, and real-time hardware monitoring utility developed by TechPowerUp for Microsoft Windows. Designed for gamers, 3D visualizers, hardware overclockers, and GPU miners, GPU-Z provides complete transparency into NVIDIA GeForce, AMD Radeon, Intel Arc, and Apple/Qualcomm graphics hardware, reporting GPU architecture, die size, transistor counts, VRAM specifications, PCIe bus link state, VBIOS versions, and live temperature/voltage sensor logs with microsecond precision.
🌟 Core Architecture & Engineering Highlights
GPU-Z interfaces directly with graphics card firmware, display driver APIs, and motherboard PCI-Express bus controllers.
Direct Video BIOS (VBIOS) Extraction & Inspection
GPU-Z communicates with the graphics card EEPROM controller, allowing power users to dump and backup their graphics card's raw VBIOS (Video BIOS) ROM image directly to disk. It displays UEFI GOP compliance, power limit target ranges, and cryptographic signature verification.
Real-Time PCIe Bus Load Render Test
To accurately detect whether your graphics card is operating at its maximum PCI-Express link speed (e.g., PCIe 4.0 x16 vs power-saving PCIe 1.1 x16), GPU-Z features an integrated PCIe Render Test. Clicking the render test generates a lightweight Direct3D load to wake the GPU from low-power idle states and verify actual bus bandwidth.
Multi-Sensor Telemetry & Thermal Junction Logging
Through direct driver and hardware sensor hooks, GPU-Z reads GPU Core Temperature, Hot Spot Temperature, GDDR6/GDDR6X VRAM Junction Temperature, VRM Power Stages, Board Power Draw (Watts), and dual-fan tachometer RPM speeds, logging telemetry to CSV files for comprehensive thermal throttling analysis.
⚙️ Key Capabilities & Workflow Features
GPU-Z provides a complete set of diagnostic tools for diagnosing graphics hardware performance and stability.
1. Graphics Card Tab (Full Architectural Breakdown)
View GPU codename (e.g., AD103, Navi 32), fabrication node, die surface area (mm²), transistor count (millions), release date, DirectX 12 Ultimate feature level support, CUDA / Stream Processor core counts, and base/boost/memory clock frequencies.
2. Sensors Tab (Live Telemetry & Graphing)
Monitor real-time sensor graphs displaying GPU Core Clock, Memory Clock, GPU Temperature, GPU Load %, Memory Used (MB), CPU Temperature, and System RAM usage with configurable sensor refresh rates (0.1s to 10s).
3. Advanced Tab (Detailed Subsystem Diagnostics)
Inspect deep hardware subsystems, including NVIDIA Resizable BAR state, Vulkan extensions, OpenCL platforms, DirectX Raytracing (DXR) capabilities, ASIC Quality scores, and WDDM display driver details.
4. Fake GPU Detection & Cryptographic Validation
GPU-Z features automated forensic detection for counterfeit graphics cards. If a seller modified a legacy GTS 450 to masquerade as an RTX 3060, GPU-Z immediately flags the card with a prominent [FAKE] warning badge in the name field, protecting buyers from fraudulent hardware.

❓ Frequently Asked Questions (FAQ)
What is the difference between GPU Temperature and Hot Spot Temperature in GPU-Z?
"GPU Temperature" reports the average edge thermal reading across the silicon die, while "Hot Spot Temperature" measures the single hottest sensor point located directly inside the computing core (often 10°C to 15°C higher under load).
Can GPU-Z extract and save my graphics card's BIOS?
Yes! Click the small chip icon next to the BIOS Version field on the main tab and select Save to file... to export a clean .rom backup of your VBIOS.
What does the [FAKE] warning mean in GPU-Z?
If GPU-Z displays [FAKE] in the graphics card name field, your graphics card is a counterfeit hardware product containing an older, weaker GPU chip reprogrammed to display a false model name.
