Phenom II X4 910 vs i5-2500K - Need For Speed: Payback GTX 1660 Ti Max-Q - Game Performance Benchmarks

Multi-Thread Performance

Single-Thread Performance

Phenom II X4 910

• The Phenom II X4 910 has higher Level 2 Cache. Data/instructions which have to be processed can be loaded from the fast L2 and the CPU does not have to wait for the very slow DDR RAM

i5-2500K

• 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 i5-2500K 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.
• The i5-2500K has a smaller process size. The faster a transistor can toggle on and off, the faster it can do work. And transistors that turn on and off with less energy are more efficient, reducing the operating power, or “dynamic power consumption,” required by a processor.
