Our Verdict on Each
A very fast high-end desktop CPU that delivers elite single-thread and strong multi-thread performance, but at the cost of high power draw, demanding cooling, and a socket with no upgrade path beyond this generation.
Best for: Enthusiasts who want the fastest possible Intel platform for a mix of high-refresh gaming and content creation, and who already own or are willing to buy robust cooling and a high-end Z690/Z790 motherboard.
Read the full reviewA flagship HEDT chip with massive multi-threaded throughput and abundant I/O, but high power draw and aging platform make it a specialist choice today.
Best for: Secondary workstation or used-market build needing lots of PCIe lanes and cores on a budget
