4 – Geometry Instancing Tests



Testbed:
- CPU: Intel Core i7 960 @ 3GHz
- RAM: 4GB DDR3 Corsair Dominator 1600MHz
- Mobo: Gigabyte GA-X58A-UD5
- PSU: Antec TPQ 850W
- OS: Windows 7 64-bit
- GeForce driver: R257.21
- Radeon driver: Catalyst 10.6

Graphics cards:
- EVGA GTX 480
- Radeon HD 5870 reference board

For each test, I read the GPU usage with EVGA Precision and the CPU usage with Windows task manager:

EVGA Precision

Windows task manager
12% or 13% means one logical CPU core is fully used.



Here are the results (default resolution: 1024×600 and default camera position):
