CPU Comparison

Intel Core i5-8305G vs Intel Core i9-8950HK

A side-by-side comparison of specs, performance and value. The Intel Core i5-8305G is a quad-core mobile processor born from a unique partnership between Intel and AMD. Released as part of the Kaby Lake-G lineup, it combines an Intel 14nm CPU with a dedicated AMD Radeon RX Vega M GL discrete-class GPU on a single package. Operating at a base clock of 2.8 GHz and boosting up to 3.8 GHz, it features 4 cores, 8 threads, and 6MB of L3 cache. The standout feature is the integrated Radeon graphics with its own HBM2 memory, offering performance levels unattainable by standard integrated graphics of the era. With a 65W TDP, it targets high-performance thin-and-light laptops and small form factor PCs that require genuine gaming capability without the bulk of traditional discrete graphics. This processor represents a fascinating experiment in semiconductor packaging and collaboration, delivering robust 1080p gaming performance and strong compute capabilities in a compact form factor.
