Lenovo laptops: Difference between "Lenovo Dynamic Graphics" and "High Performance"

I was curious just like the original poster, so I ran benchmarks on my Lenovo IdeaPad Y580 when I first got it back in November. My conclusion is that the GPU generates frame rates between 10 and 11% higher on Lenovo Dynamic than on High Performance. Additionally, and this is a useless data point, the system decrypts data encrypted with RC5-72 13% faster on Lenovo Dynamic than on High Performance.

TEST A: High Performance A benchmark app was run with the power management set to "High Performance". The benchmark was run after a cold boot. The system was literally at room temperature when the boot started.

Here are the results:

• 3DMark Score P2346
• Graphics Score 2150
• Physics Score 6023
• Combined Score 1906
• Graphics Test 1 10.32 FPS
• Graphics Test 2 9.89 FPS
• Graphics Test 3 13.53 FPS
• Graphics Test 4 6.42 FPS
• Physics Test 1 9.12 FPS
• Combined Test 8.87 FPS

Here were the temps in F at the end of the test: // CPU Pkg - 194.0 // GPU 149.0 // HDD 113.0 //

Test B: Lenovo Dynamic Graphics

• 3DMark Score P2542
• Graphics Score 2338
• Physics Score 5888
• Combined Score 2124
• Graphics Test 1 11.55 FPS
• Graphics Test 2 10.88 FPS
• Graphics Test 3 14.62 FPS
• Graphics Test 4 6.83 FPS
• Physics Test 1 8.69 FPS
• Combined Test 9.88 FPS

Here were the temps in F at the end of the test: // CPU Pkg 197.6 // GPU 161.6 // HDD 114.8 //

Appendix A: RC5-72 Results On the High Performance setting, the system's GPU solves 111,330,057 keys per second using the distributed.net client. On the Lenovo Dynamic Graphics setting, the GPU solves 126,623,174 keys per second using the distributed.net client.
