CPU Comparison
Intel Core i5-8500T vs Intel Core i7-5775C
A side-by-side comparison of specs, performance and value. The Intel Core i5-8500T is a low-power desktop processor from the 8th generation Coffee Lake family. Released in April 2018, it is built on the 14nm process and features 6 cores and 6 threads. The 'T' suffix indicates a 35W TDP, making it ideal for small form factor PCs, AIOs, and office environments. The base clock is 2.1 GHz, with a maximum turbo boost of 3.5 GHz, offering a good balance between power efficiency and performance. It includes 9 MB of Intel Smart Cache and supports dual-channel DDR4 memory up to 2666 MT/s. The integrated Intel UHD Graphics 630 provides basic display capabilities. With 16 PCIe 3.0 lanes, it offers adequate expansion for a discrete GPU and NVMe storage. Compatible with LGA 1151 motherboards on 300-series chipsets, the i5-8500T is a step up from the 8400T, providing higher clock speeds for users needing more responsiveness in a compact footprint.
