AMD's Ryzen 5 8600G isn't the most muscular CPU you can buy, but it drives competitive integrated-graphics performance for its price. It's an ideal chip for budget gaming PCs.
Intel's power-hungry, pricey Core i9-14900KS delivers too little extra performance versus its Core i9-14900K kin to merit the extra cash. Intel's previous-gen Core i9-13900K comes much more highly recommended.
The Intel Core i5-13400F is a well-priced processor that's a fine fit for a budget gaming PC, but don't expect it to pair well with a high-end graphics card.
AMD's Ryzen 7 8700G is an excellent single-chip gaming solution, especially for small PCs that can't house a graphics card, but it just can't beat a conventional CPU and GPU combination on price/performance.
