Are they? The i5-10600K sells for $262. Its closest competitor is ryzen 3600/3600x, which currently sell for $172/$200 respectively. For $62 (33%) more, is it really 33% faster than AMD? There are lower tier skus (eg. i5-10500) that match AMD's pricepoint, but I doubt they match 3600/3600x's performance. At the high end, the i9-10900K ($488) is competing against the ryzen 3900x, which currently sells for $400 and has 20% more cores.
