  4. Topic6.1.3 • Identify the limitations of a rangeof resources in a specified computer system

  5. Case study: 3D graphicsrendering • Single processor computers may not be able to render3D • graphics as effectively as multicore/systems with aGPU

  6. What would the consequence be if you had tolimit… • Primarymemory? • Secondarystorage? • CPUspeed? • CPUcores? • Connectivity? Content developed by Dartford Grammar School Computer ScienceDepartment

  7. Would this be a good gamingsetup? What is limiting thissystem?

  8. Would this be a video editingsetup? What is limiting thissystem?

  9. Would this be good setup for watchingmovies? What is limiting thissystem?
