AMD and Intel fight their biggest battles in the Core i7/Ryzen 7 and Core i5/Ryzen 5 families that comprise the bulk of the PC market. As we can see, prices are generally comparable between the two companies' lineups, with Ryzen 7/Core i7 spanning from $303 to $360, while the Ryzen 5/Core i5 series span from $182 to $260.
Even after Intel's adjustments to the Coffee Lake Core i7 series, AMD holds the advantage of more cores in its Ryzen 7 product line. Intel's Core i7 models come with six cores and twelve threads, while AMD's Ryzen 7 line wields eight cores and sixteen threads.
The Ryzen 5 and Core i5 series are the general-purpose workhorses of most desktop PCs, and both lineups come with six cores. Intel has segmented its product stack by disabling Hyper-Threading on its Core i5 models, meaning software can only assign a single thread to each core. Meanwhile, AMD's Ryzen 5 models come with the company's Simultaneous Multi-Threading, which allows software to schedule two threads to each core at the same time. That gives Ryzen 5 an advantage with a total of twelve threads.
But not all cores are created equal. Intel holds the per-core performance advantage with its higher frequencies and generally processes more instructions per clock (IPC). Ryzen 7 tops out at 4.3 GHz with the 2700X model, while Intel's Core i7-8700K stretches up to 4.7 GHz. Intel's per-core performance advantage equates to more performance and responsiveness in lightly-threaded applications, such as most games and general desktop PC applications.
AMD's Ryzen 2 (2000 series) offers improved performance in heavily-threaded productivity applications, like rendering, video editing, and transcoding, and it also boosts performance in game titles that can utilize the extra cores and threads. Ryzen 2 also comes with Precision Boost 2, which is similar to Intel's multi-core boost implementation that provides higher boost frequencies when applications exercise multiple cores at once. Neither company discloses the full list of turbo frequencies, so it's hard to make comparisons based on the specifications alone, but we’ll put the processors to the test shortly.
