i3-8300 vs i3-12300 - Need For Speed: Heat Graphics 512SP Mobile - Game Performance Benchmarks

Multi-Thread Performance

Single-Thread Performance

i3-8300

• The i3-8300 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
• 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.

i3-12300

• The i3-12300 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 i3-12300 has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.
• The i3-12300 is more power efficient and generates less heat.
• The i3-12300 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.
