i5-12400 vs Phenom II X4 905e - Need For Speed: Payback RTX 4080 Max-Q - Game Performance Benchmarks

Multi-Thread Performance

Single-Thread Performance

i5-12400

• The i5-12400 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 i5-12400 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 i5-12400 has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.
• The i5-12400 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.

Phenom II X4 905e

• The Phenom II X4 905e 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
