Core i5-3450 vs Core i7-975 comparison

According to the hardwareDB Benchmark tool, the Core i5-3450 is faster than the Core i7-975. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-975 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i7-975 has more threads. Our comparison shows that the Core i7-975 has a slightly higher clock speed compared to the Core i5-3450. Also, the Core i7-975 has a slightly higher turbo speed. A Core i5-3450 CPU outputs less heat than a Core i7-975 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 i5-3450 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
