Our take on the HPE 654420-B21 Intel Xeon 6-Core 2.0 GHz Processor

The HPE 654420-B21 is an Intel Xeon six-core server processor running at 2.0 GHz with 15 MB of cache and a 95 W TDP. It fits Socket LGA2011, the platform used in HPE ProLiant Gen8 servers, so it is a replacement or upgrade part for existing machines rather than a chip for a new build. At $163 at Global One Technology as of November 3, 2026, it is a low-cost way to add cores to an older server. Only one store lists it new, so there is no meaningful price spread to compare against.

Pros
  • Six cores and 15 MB cache suit light virtualization and file serving
  • 95 W TDP keeps heat and power draw modest for a server chip
  • Socket LGA2011 fits HPE Gen8 ProLiant boards
  • Low price for a working server CPU
Cons
  • Old architecture with no support for current DDR5 or PCIe 5.0
  • 2.0 GHz base clock is slow by modern standards
  • Single new listing means little price competition
  • No cooler or heatsink included; server heatsinks are sold separately

Questions and answers

Is this CPU worth buying in 2026?
Only if you already own an LGA2011 HPE server that needs a six-core chip. For a new build, a modern platform is faster and more efficient at a similar total cost.
Which HPE servers does it fit?
It uses Socket LGA2011, the socket in HPE ProLiant Gen8 servers. Check your server's quickspecs before buying, since not every Gen8 model takes this part.
Does it come with a heatsink?
No. Server processors are usually sold as the chip alone, so you need the correct HPE heatsink for your chassis.
How does it compare with an eight-core Xeon?
An eight-core LGA2011 Xeon gives more threads for virtualization but draws more power and costs more. For light workloads, this six-core part is the cheaper choice.
When is the best time to buy?
Prices on legacy server parts move slowly and stock is thin. With one new listing at $163 as of November 3, 2026, waiting is unlikely to help much.
Where is the HPE 654420-B21 Intel Xeon 6-Core 2.0 GHz Processor cheapest?
At Global One Technology, for $163.00, as of our latest check.
