In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6330M are significantly better than the AMD Mobility Radeon 9700 Series.
The Radeon HD 6330M was released over three years more recently than the Radeon 9700, and so the Radeon HD 6330M is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon 9700 when running the latest games.
Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.
The Radeon HD 6330M has 896 MB more video memory than the Radeon 9700, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon HD 6330M also has superior memory performance overall.
The Radeon HD 6330M has 8.4 GB/sec greater memory bandwidth than the Radeon 9700, which means that the memory performance of the Radeon HD 6330M is marginally better than the Radeon 9700.
The Radeon HD 6330M has 80 Shader Processing Units and the Mobility Radeon 9700 Series has 2. However, the actual shader performance of the Radeon HD 6330M is 20 and the actual shader performance of the Radeon 9700 is 1. The Radeon HD 6330M having 19 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 6330M delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon 9700.
The Radeon HD 6330M requires 7 Watts to run but there is no entry for the Mobility Radeon 9700 Series.
Radeon HD 6330M is an entry-level GPU based on the 40nm Terrascale 2 architecture.
It's based on the Cedar Core (therefore related to Radeon HD 6350) and offers 80 Shader Processing Units, 8 TMUs and 4 ROPs on a 64-bit memory interface of standard DDR3. Its central clock runs at up to 500MHz and the memory clock operates at 800MHz.
Compared to Radeon HD 6350M, it should deliver similar performance as what distinguishes the two is a small memory bandwidth difference.
Almost all of today's modern games can only be played using very low resolutions such as 800x680 - 1024x768.
Notebook PCs based on AMD's mainstream notebook platform are designed to deliver real entertainment with the ultimate in HD visual performance. Superior technologies are optimized to create an immersive visual experience with improved graphics performance, fast wireless and long battery life. Add in more notebook PC choices from leading PC manufacturers and you get an incredible value one that you can only get from AMD.
