MediaTek MT6517 vs Intel Core i5-14400

The MediaTek MT6517 is an older processor designed for use in energy-efficient mobile devices like smartphones to enable basic functions.

It is manufactured using the 40 nm process, is based on the ARM Cortex-A9 architecture with typically two CPU cores, and has 0 MB of L2 and L3 cache. Its computing power is extremely limited, sufficient only for simple applications. For modern gaming, it is completely unsuitable with its integrated PowerVR SGX531 graphics and low performance.

It is characterized by extremely low power consumption and minimal TDP. Its price-performance ratio is irrelevant in a desktop context. The Intel Core i5-14400 is a current desktop processor from Intel's 14th generation, targeting the mainstream market and providing solid performance for productivity, gaming, and content creation.

It is manufactured using the 10 nm process, utilizes the modern Raptor Lake S Refresh architecture with a hybrid design of 10 cores (6 P-cores, 4 E-cores) and 16 threads, complemented by 10 MB of L2 and 20 MB of L3 cache. This processor delivers very high performance for both single-core and multi-core tasks.

For gaming, it offers excellent performance thanks to its architecture, high clock frequencies, and PCIe 5.0 support; the integrated Intel UHD Graphics 730 is sufficient for basic desktop tasks. It has a moderate TDP and offers a very good price-performance ratio in the mid-price segment. The maximum memory bandwidth is 90 GB/s.

For any form of desktop use, the Intel Core i5-14400 is the only sensible choice.
