Core i7-3820 vs Core i7-4790T specs and performance

According to the hardwareDB Benchmark tool, the Core i7-4790T is faster than the Core i7-3820. Despite this, the Core i7-3820 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count and the same number of threads. Our comparison shows that the Core i7-3820 has a slightly higher clock speed compared to the Core i7-4790T. Despite this, the Core i7-4790T has a slightly higher turbo speed. The Core i7-4790T outputs less heat than Core i7-3820 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-3820 has more threads than cores. Each physical core is split into multiple threads.
