IBM Xeon E5-2650L v2 10-Core Processor
This IBM 46W9143 is a new Intel Xeon E5-2650L v2 server processor built for LGA 771 sockets. It delivers 10 cores and 20 threads at a base frequency of 1.7 GHz with 25 MB L3 cache. The 70 W thermal design suits dense rack deployments where power density matters. It is sold as a bare processor without a cooling device.
Capacity headroom for multi-threaded server
The 10 cores and 20 threads handle virtualisation hosts, database nodes and batch compute jobs that scale across threads. A 7.2 GT/s QPI link supports dual-socket configurations for expanded throughput. The 1.7 GHz base clock limits single-thread latency-sensitive tasks, and the 70 W envelope caps sustained all-core turbo headroom.
Upgrade path from lower-core Xeon parts
This part replaces 4-core or 6-core LGA 771 Xeons when thread count matters more than peak frequency. The jump is worthwhile for workloads that saturate 20 threads within the 70 W budget. It is not for builds needing higher single-thread speed, integrated graphics or consumer desktop sockets.

Questions about this item
Will the 70W TDP of this Xeon E5-2650L v2 work with my existing LGA 771 server cooler?
The processor has a 70W thermal design power. Your current cooler must be rated for at least 70W on an LGA 771 socket to keep temperatures in check.
How can I confirm the 10 cores and 20 threads are active after installation?
Check the BIOS or operating system CPU information; it should show 10 cores and 20 threads running at 1.7 GHz base frequency with turbo available.
The listing says bare processor only — what exactly ships and what must I source separately?
Only the 46W9143 processor ships. You must supply a compatible LGA 771 heatsink, fan and thermal paste yourself.
