Benchmark Results

Running at 915MHz GPU and 1502MHz VRAM with all tests ran on internal LCD and PhysX set to CPU.

3Dmk13-FS.GPU=5065

3Dmk11.GPU=7027

Configuration Details

This has been my easiest and favorite implementation ever since Lenovo listened to their userbase and updated the BIOS to do a dynamic TOLUD adjustment when an EC device is detected. You simply plug the EC with the laptop shutdown and you are good to go. Also you can safely remove the adapter and simply put the laptop to sleep to reattach it later without having to do a power cycle. Hopefully that feature will someday appear in all the other Thinkpads.

Will be updated with scores for external LCD in the future.
