Our Verdict on Each
A milestone eight-core HEDT processor with strong multi-threaded performance and expansion options, but high power draw and an aging platform limit its appeal in new builds.
Best for: Upgrading or maintaining an existing X99 system at very low cost; secondary workstation rigs.
Read the full reviewThe i7-7800X offers quad-channel memory and decent multi-core performance for its era, but higher power draw and limited PCIe lanes make it a niche choice today versus modern mainstream platforms.
Best for: Budget upgrade on existing X299 platform with DDR4 investment
