Radeon Hd 3400
The AMD ATI Mobility Radeon HD 3400 IGP (or just Radeon HD 3400) is most probably a chipset graphics card for laptops. It is used in the Lenovo Edge laptops with AMD processor and should be slower than the HD 4225 IGP. Therefore, it can be based on the HD 3200 or HD 4225 chipset with different clock speeds. See both pages for more information on the graphics card and benchmarks.
