i5-12600K vs i5-4670K - Ashes of the Singularity GTX 660M - Game Performance Benchmarks

Multi-Thread Performance

Single-Thread Performance

i5-12600K

• The i5-12600K 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 i5-12600K 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 i5-12600K 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 i5-12600K 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.

i5-4670K

• The i5-4670K 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
• The i5-4670K is more power efficient and generates less heat.
• The i5-4670K 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.
