Gaming on mainstream laptops becomes a reality.
Before I go any further, I’d like to state that the current AMD drivers for their new AMD VISISON Engine Control Center is still in its very early stages. As such I saw very erratic results when running the laptop in CrossFire mode (using both HD 6620M & 6630M). Right now it would seem that performance on DX9 titles across the board is abysmal in CrossFire mode as only one GPU is being used, where only DX10 and DX11 titles are taking advantage of two cards. Even then, however, there are certain DX11 titles where CF isn’t being utilized properly.
All the below tests were done at the native resolution of 1366×768 with the following settings:
Scaling on DX11 titles seems to be consistent using dual GPUs, but scaling isn’t good in Metro 2033 and Lost Planet 2. While the developers may have some level of unoptimization for the Llano APUs, AMD obviously needs to put in a lot of effort for many titles with CrossFire support. As you can see, DX9 titles aren’t using the 2nd GPU at all. In fact, below I have given an example of GPU usage between Team Fortress 2 (DX9) using one GPU and Just Cause 2 (DX10) using both GPUs.
This is a huge issue for AMD right now; they need to get the drivers right with proper support for titles across the board. I must say that just the results from the onboard graphics were phenomenal; I haven’t seen performance like this from any Intel HD graphics chip to date, including their latest Sandy Bridge platform. With an included discrete graphics card, we have already glimpsed at how amazing the performance can get.
