AMD Ryzen 7 7800X3D

6.7/10verdict: buy

The Ryzen 7 7800X3D is for gamers building an AM5 desktop who want strong gaming performance from an eight-core chip. It also suits developers and homelabbers who want DDR5, PCIe 5.0 and optional ECC support on one platform. Buyers who need many cores, low power draw or media transcoding from the processor itself should check the limits first.

Intel Core Ultra 7 processor 270K Plus

6.5/10verdict: buy

The Core Ultra 7 270K Plus is for builders who want many cores for compiling, VMs and rendering on a desktop budget. It also suits media server owners who value HEVC hardware encoding from the integrated graphics. It is a poorer fit for always-on machines where idle power matters, or for gaming-first builds.
