Core i3-8100 vs Core i7-3820 benchmarks

In our benchmarks, the Core i7-3820 beats the Core i3-8100 in overall performance. Despite this, the Core i3-8100 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i7-3820 has more threads. In terms of clock speed, the Core i3-8100 and Core i7-3820 are identical in this regard. Despite this, the Core i7-3820 has a slightly higher turbo speed. A Core i3-8100 CPU outputs less heat than a Core i7-3820 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i3-8100 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
