With ho-hum CPU performance for the money, AMD's gaming-minded Ryzen 7 7800X3D is a tough sell as a mainstream CPU, given that its strengths will benefit only a small sliver of gamers.
Intel's Core i9-13900KS processor is scarcely different from its Core i9-13900K, except that it costs more. Its 6GHz peak clock speed is exciting for bragging rights, but bears little fruit in most real-world situations.
AMD's Ryzen 9 7950X3D is a speedy AM5 processor, but its added cache doesn't do enough to justify its effective price premium. Current Core i9 chips, and AMD's own 7950X, tamp down its relative value.
AMD's Ryzen 7 7700 is a respectable processor with a worthy stock cooler and fast performance, especially in games, but it can't quite topple the Intel Core i5-13600K, which matches it in price.
