The 24-core Raptor Lake Refresh chip hits 6.0GHz boost and 5.8GHz Turbo Boost Max, with 36MB L3 cache and PCIe 5.0 support. Its unlocked multiplier and 253W turbo power make it a strong choice for overclocking and heavy multitasking. Best for gamers and content creators who need top-tier single-thread performance and don't rely on integrated graphics.

The 64-core, 128-thread Shimada Peak chip with a 5.4GHz boost and 256MB L3 cache delivers top-tier multi-threaded performance, scoring 143,309 in PassMark. Its unlocked sTR5 socket and PCIe 5.0 support make it a flexible choice for heavy workloads, though the 350W TDP and no integrated graphics require a dedicated GPU. Best for professionals running AI models, rendering, or server tasks that demand maximum core count and memory bandwidth.

The 16-core Raptor Lake design with 8 P-cores and 8 E-cores hits 5.2GHz boost, backed by 30MB L3 cache and a 65W base TDP for efficient multitasking. It supports both DDR5 and DDR4 memory and includes Intel UHD Graphics 770, making it a flexible drop-in for LGA1700 boards. Best for productivity-focused builders who want strong multi-threaded performance without a high power draw.

With 16 cores and 32 threads reaching a 3.9GHz boost, this Xeon Gold processor delivers consistent throughput for multi-threaded server tasks, backed by a substantial 37.5MB L3 cache. Support for up to 4TB of DDR5 memory and PCIe 5.0 connectivity ensures it can handle dense virtualization and memory-intensive workloads without bottlenecking. This chip is best for data center operators running large-scale database and containerized application servers.

The 16-core, 2.0GHz Xeon Silver 4514Y provides hardware-enhanced performance for entry-level data center computing with a 150W TDP on the LGA4677 socket. Its 30MB of L3 cache and improved memory speed deliver essential power efficiency for network and storage tasks. This processor is best for IT administrators deploying single-socket servers handling light virtualization and file services.

The 10-core, 20-thread Skylake X chip hits 4.4GHz turbo and 19.25MB cache, with a 165W TDP and unlocked multiplier for overclocking. It supports quad-channel DDR4-2666 and Intel Optane memory, but only works with X299 motherboards. Best for productivity-focused builders who need heavy multi-threaded performance for rendering or virtualization on a high-end desktop.

With 18 cores and 36 threads, this 22nm Xeon E5 v3 processor delivers strong parallel throughput for virtualized environments, supported by a massive 45MB L3 cache and up to 768GB of DDR4 memory. Its 145W TDP and single-socket LGA 2011-v3 design make it a cost-effective drop-in upgrade for aging workstation or server infrastructure. This chip is best for homelab operators and IT admins running multiple VMs or threaded server applications who don’t require high single-core speed.
