Phenom II X4 820 vs Phenom II X6 1075T - Need For Speed: Heat R9 290X - Game Performance Benchmarks

Multi-Thread Performance

Single-Thread Performance

Phenom II X4 820

• The Phenom II X4 820 is more power efficient and generates less heat.

Phenom II X6 1075T

• The Phenom II X6 1075T has higher Level 3 Cache. This is useful when you have substantial multiprocessing workloads, many computationally intense simultaneous processes. More likely on a server, less on a personally used computer for interactive desktop workloads.
• The Phenom II X6 1075T has more cores. The benefit of having more cores is that the system can handle more threads. Each core can handle a separate stream of data. This architecture greatly increases the performance of a system that is running concurrent applications.
• The Phenom II X6 1075T has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.
• For some games, a cpu with a higher clock speed, or in a technical name IPC (Instructions per clock), has better results than other CPU's with higher core count and lower core speed.
• The Phenom II X6 1075T has a higher turbo clock boost. Turbo Boost is a CPU feature that will run CPU clock speed faster than its base clock, if certain conditions are present. It will enable older software that runs on fewer cores, to perform better on newer hardware. Since games are software too, it is also applicable to them.
