To find your GPU, open Device Manager or download and use GPU-Z.
You're hitting a CPU bottleneck. Dolphin needs fast single-core speeds from the CPU to run at full speed, and your CPU is a low power model meant to run at low speeds.
Some things to do to speed up your computer (don't expect full speed)
1) Update drivers, Windows updates, DirectX Web installer (may be missing some parts), and latest version of Visual C++
2) Make sure under Power Management in Windows you're running in High Performance. Also set your GPU to run at high performance: https://forums.dolphin-emu.org/Thread-unofficial-laptop-performance-guide?highlight=laptop+performance+guide
3) Use the OpenGL backend on one of the latest dev builds, as it is faster than D3D. The current dev build is 4.0-780
You should probably look into getting new hardware, preferably a desktop so you can upgrade it easier. Intel Haswell CPUs are the current best for Dolphin (we can recommend some good, cheap hardware if you want)
