Intel Core i5-12400

The Core i5-12400 is a 6 core CPU from Intel released in 2022. This chip has a very good overall score at 70% in our CPU benchmark. Our gaming benchmark shows that this CPU is a very good processor for gaming, with a score of 96%. As for multitasking and heavy workloads, the Core i5-12400 scores 62% and 60% respectively. Indeed, this is a very good rating for very heavy workloads.

The Core i5-12400 has 6 cores and 12 threads. This CPU makes use of simultaneous multithreading technology to improve performance on parallel tasks. Each physical CPU core is divided into multiple logical processors. This Intel CPU has a clock speed of 2.5 GHz and a turbo speed of 4.4 GHz : a higher clock speed that can be reached when thermals and power delivery allow. This CPU has a locked multiplier, so you are not able to overclock it beyond this frequency.

As for memory, the Core i5-12400 makes use of DDR5-4800 memory. The faster the memory, the better. Faster memory means that the CPU doesn't have to wait to get the data it needs. It can accommodate a maximum of 128 GiB of memory. Furthermore, this chip can handle up to 2 channels of RAM, a multichannel memory architecture allows for higher data transfer between the CPU and the memory. However, to take advantage of this, you must have enough memory slots filled.

In terms of cache, the Core i5-12400 has 480 KiB of level 1 cache, and 18 MiB of level 3 cache. This is a fast memory located close to the processor, which stores copies of frequently used data from main memory.

This CPU has fast connectivity with support for PCI-Express Gen 5. The faster the PCIe link, the better. This allows for better performance with GPUs and NVME SSDs. It has a total of 20 PCIe lanes.

Power and thermals for the Intel Core i5-12400 CPU are a TDP (Thermal Design Power) of 65 watts. This measures the amount of heat the processor produces when running at full load. This isn't a measure of power consumption, but it's good estimate.
