GPU Shark is available for Microsoft Windows only (XP, Vista and Seven). GPU Shark offers a global view of all your graphics cards in a single window. GPU Shark can display for every GPU the clock speeds (GPU core, memory and shader processors), performance states (or PStates), GPU fan speed, and GPU/memory/MCU usage.
GPU-Shark gives an overview of all your GPUs and has two viewing modes: simplified and detailled. In simplified mode (default), only the essential hardware information is displayed: graphics card name, temperatures (GPU, PCB) and clocks (GPU, memory and shader). In detailed mode all data is available: GPU codename, driver version, bios version, device ID, etc.
The main feature of GPU-Shark is to monitor all available GPUs and visualize them all in a single window. That’s the fondamental difference with GPU Caps Viewer. Indeed GPU Caps is focused on the main graphics card, the one that can run OpenGL and Direct3D apps. With GPU Caps, you can’t have access to the information of secondary cards. What’s more, GPU Caps has many other features like OpenCL or CUDA data and has several real time 3D demos (OpenGL and OpenCL). All these features have a drawback: GPU Caps comes with several files (DLLs and demos data).
