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