As it's an intergrated GPU, it shares the on board memory & will use that if it needs more.

While graphics cards for desktop PCs have large amount of memory onboard them, laptop graphics solution use part of the memory available to the entire laptop.

-----------------------------------------------------------

The AMD Radeon HD 8400 is an integrated DirectX 11.1 graphics card typically paired with AMD Kabini-class APUs (for example, the A6-5200). It has 128 shader cores and two Compute Units based on the GCN architecture and is clocked at 600 MHz with no support for Turbo. The GPU does not have dedicated VRAM and will access the main memory of the system (up to single-channel DDR3L-1600).

The HD 8400 integrates both UVD 4.2 and VCE 2.0 video encoders. It supports up to two external monitors via VGA, DVI, HDMI 1.4a and DisplayPort 1.2.

Depending on the benchmark, the performance of the Radeon HD 8400 is similar to some faster Intel HD Graphics 4000 models. This is on par with a dedicated Radeon HD 6490M, but is still too slow for a number of demanding games as of 2013/2014. However, many older and less demanding games will run fluently if the performance of the CPU is sufficient.

Processor: AMD A6-5200 (with his own GPU: Radeon HD 8400)
Video Chipset: AMD A68M with 2Gb GDDR3

In 2D: system will use GPU from processor (energy saving) and some % memory from RAM.
In 3D: system will use main GPU with 2Gb GDDR3
