In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6645G2 are marginally better than the Intel HD Graphics Mobile (Broadwell).
The Radeon HD 6645G2 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.
The Graphics Mobile was released over three years more recently than the Radeon HD 6645G2, and so the Graphics Mobile is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD 6645G2 when running the latest games.
The HD Graphics Mobile (Broadwell) and the Radeon HD 6645G2 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The Graphics Mobile has 4.3 GB/sec greater memory bandwidth than the Radeon HD 6645G2, which means that the memory performance of the Graphics Mobile is marginally better than the Radeon HD 6645G2.
The HD Graphics Mobile (Broadwell) has 12 Shader Processing Units and the Radeon HD 6645G2 has 560. However, the actual shader performance of the Graphics Mobile is 10 and the actual shader performance of the Radeon HD 6645G2 is 0. The Graphics Mobile having 10 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics Mobile delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon HD 6645G2.
The HD Graphics Mobile (Broadwell) requires 4 Watts to run but there is no entry for the Radeon HD 6645G2.

| Mini Review | Intel HD Graphics Mobile (Broadwell) are integrated graphics in the budget Celeron and Pentium Broadwell Mobile processors. Their performance depends on the processor they are integrated on, as the latter defines the Base and Boost Clock, as well as on the SYSTEM RAM, which defines the operating memory clock, and whether the GPU accesses a 64-bit or 128-bit memory interface. Best case scenario, the Intel HD Graphics Mobile (Broadwell) performs on par with Intel HD 4000 Graphics and so most modern demanding games will not be playable. Less graphically intense games will be playable at lower graphics settings. | Radeon HD 6645G2 is a combination of an entry/middle class level AMD Radeon HD 6490M and an integrated AMD Radeon HD 6620G (APU). This system is known as AMD Dual Graphics and also asymmetric CrossFire. It uses Alternate Frame Rendering (AFR) to render different frames on the two graphic cores and can suffer from micro-Stuttering. The performance relies on solid driver support and, at times, it might even be worse the performance of the Radeon HD 6490M by itself. Only DX10 & DX11 modes are supported which means a game set with lower settings and not set to use DX10/DX11 is not accelerated (does not make use of the asymmetric crossfire feature within the card). Due to the micro stuttering and performance problems, Dual Graphics may sometimes cause more problems than the possible dual card performance gains they suggest. | |||
