AMD Opteron 2352 vs HPE 654420-B21 Xeon 6-Core

These are server processors from different generations and different sockets, so they are not interchangeable in one machine. The Opteron 2352 is a 2007-era Socket F quad-core; the HPE 654420-B21 is a Socket LGA2011 six-core Xeon with far more cache. Buy the Xeon for any LGA2011 server build; the Opteron only makes sense as a drop-in replacement for an existing Socket F system. No prices were provided for either part, so compare live store prices on Deal.ai before buying.

AMD Opteron 2352

AMD Opteron 2352 2.1 GHz 4-Core Processor

See all prices and details

Choose the AMD Opteron 2352 if you are repairing or upgrading an existing Socket F server board that already takes this chip.

Pros
  • Slightly higher clock speed at 2.1 GHz
  • Same 95 W TDP as the Xeon
  • Cheap way to keep an old Socket F server running
  • Quad-core is enough for light file and print roles
Cons
  • Only 2 MB of cache
  • Older DDR2 platform with lower memory bandwidth
  • No path to modern server boards
  • Four cores trail six in multi-threaded work
HPE
HPE 654420-B21 Intel Xeon 6-Core 2.0 GHz Processor

HPE 654420-B21 Xeon 6-Core

HPE 654420-B21 Intel Xeon 6-Core 2.0 GHz Processor

See all prices and details

Choose the HPE Xeon 654420-B21 if you are building or servicing a Socket LGA2011 server and need six cores with 15 MB of cache.

Pros
  • Six cores for better multi-threaded throughput
  • 15 MB cache, over seven times the Opteron's
  • Four-channel DDR3 memory support
  • Fits many LGA2011 servers, so parts and boards are easier to find
Cons
  • Slightly lower 2.0 GHz clock
  • Needs an LGA2011 board and DDR3 memory
  • Sandy Bridge-EP generation is itself dated
  • Check that your server's BIOS and heatsink support this exact part

What reviewers say

AMD Opteron 2352

Reception comes from retro hardware and home lab communities rather than mainstream buyers. Owners treat it as a cheap way to add cores to old Socket F servers, and they accept its age and power draw as the price of that.

What people mention
  • PerformanceCriticisedOwners say per-core speed is slow by modern standards, fine only for light or legacy workloads.
  • CompatibilityMixedIt works only in Socket F (1207) boards with Barcelona support, which limits who can use it.
  • PricePraisedBuyers like that four cores cost very little on the used market.
  • Power drawMixed95 W is manageable for its class but inefficient next to current CPUs.

HPE 654420-B21 Xeon 6-Core

Reception is thin because this is an OEM server part, but owners of E5-2620 v2 systems describe it as a reliable, low-power workhorse for light server duties. Most complaints center on its low clock speed and the age of the platform rather than the chip itself.

What people mention
  • PerformanceMixedOwners say six cores help with parallel workloads but the 2.0 GHz clock holds back single-threaded tasks.
  • Power drawPraisedThe 95 W TDP is considered easy to cool in server chassis.
  • Platform ageCriticisedBuyers note LGA2011 and DDR3 make it a dead-end upgrade.
  • ReliabilityPraisedLong-uptime server owners report no stability issues.

Questions and answers

Can I put the Opteron 2352 in an LGA2011 board?
No. The Opteron uses Socket F and the Xeon uses LGA2011. The sockets and pin layouts are completely different, so neither chip fits the other's board.
Which is faster for multi-threaded server work?
The Xeon. It has six cores and 15 MB of cache against four cores and 2 MB, which usually outweighs the Opteron's 100 MHz clock advantage.
Do they use the same amount of power?
Yes, both are rated at 95 W TDP. Real draw depends on the board, memory and load, but the headline rating is identical.
Which lasts longer?
The Xeon's platform is newer and its boards and DDR3 memory are easier to source, so it is the more serviceable choice. Both are old parts, so condition of the specific unit matters more than the model.
Is the Xeon worth extra money over the Opteron?
If you need an LGA2011 chip, yes, since the Opteron will not fit at all. If you already own a Socket F server, the Opteron is the only one of the two that works.
What memory does each need?
The Opteron platform uses registered DDR2 on Socket F boards. The Xeon uses DDR3 across up to four channels on LGA2011 boards.
