Intel Core i7-8557U

The Core i7-8557U is a 4 core CPU from Intel released in 2019. This chip has a very good overall score at 50% in our CPU benchmark. Our gaming benchmark shows that this CPU is a very good processor for gaming, with a score of 62%. As for multitasking and heavy workloads, the Core i7-8557U scores 46% and 45% respectively. Indeed, this is a very good rating for very heavy workloads.

The Core i7-8557U has 4 cores and 8 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 1.7 GHz and a turbo speed of 4.5 GHz : a higher clock speed that can be reached when thermals and power delivery allow.

As for memory, the Core i7-8557U makes use of DDR4-2400 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 32 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. Error correcting memory is not supported on this processor.

This CPU has fast connectivity with support for PCI-Express Gen 3. The faster the PCIe link, the better. This allows for better performance with GPUs and NVME SSDs. It has a total of 16 PCIe lanes.

Power and thermals for the Intel Core i7-8557U CPU are a TDP (Thermal Design Power) of 15 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.
