Core i5-3450 vs Core i7-3820QM specs and performance

According to the hardwareDB Benchmark tool, the Core i7-3820QM is faster than the Core i5-3450. Despite this, the Core i5-3450 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-3820QM has more threads. With our hardware info, we find that the Core i5-3450 has a slightly higher clock speed than the Core i7-3820QM. Despite this, the Core i7-3820QM has a slightly higher turbo speed. The Core i7-3820QM outputs less heat than Core i5-3450 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core i5-3450 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
