Radeon HD 7420G Review
Radeon HD 7420G is an integrated GPU on the entry-level Trinity CPUs.
It's based on the 32nm Terascale 3 architecture and offers 128 Shader Processing Units, 8 TMUs and 4 ROPs. The memory interface will depend on whether or not the laptop's system RAM is dual channelled (128-bit if so, 64-bit, if not) and the operating memory clock can be up to 800MHz (max speed supported by the CPU). The central unit runs at 480MHz and will go up to 655MHz in Turbo Mode. Expect a TDP of up to 35 Watt.
Its performance is below both Intel HD 4000 Graphics and previous in series - Radeon HD 7400G, despite the naming, due to the lesser Shaders count which proves useful in most of today's modern games.
Most of today's modern games will have to be played at the lowest settings, while extremely demanding games (e.g. Crysis 3) are most likely unplayable.
