CPU Comparison

Intel Core i5-2390T vs Intel Core i5-650

A side-by-side comparison of specs, performance and value. The Intel Core i5-2390T is a low-power dual-core processor from the Sandy Bridge generation, featuring Hyper-Threading to handle four threads simultaneously. With a thermal design power of just 35 watts, it was designed specifically for compact desktops and all-in-one PCs where cooling space and power delivery are strictly limited. Despite its small power footprint, it operates at a respectable 2.7 GHz base frequency and can turbo boost up to 3.5 GHz under load. It includes the Intel HD 2000 integrated graphics, providing basic display output without the need for a dedicated graphics card. This chip represents a unique era in computing when dual-core i5s were still prevalent in the market, serving users who needed hyper-threading capabilities and modern instruction sets like AVX without the heat output of a quad-core chip.
