"Simulating" Cpus

I watched linustechtips' how many cores is enough for gaming video and i noticed he went in the bios to disable core on his i7 to test different amounts of core performance. i was wondering if it is possible to take a Cpu and use it to simulate a "worse" cpu on the same architecture.

Example:

if i took an i7-3770k and disabled 4 thread and set the clock speed to 3.4 ghz, would i have an i5 3570k or something similar?

Hyperthreading and core simulation are two different things. Hyperthreading only duplicates certain resources in each physical core to achieve a new "logical core". Processor simulation would be more like the ALU and CPU projects that you see in Minecraft.

In this scenario, technically yes, it would then be an i5 but the system and applications would still identify it as an i7-3770.
