Intel Xeon E-2276G 6-core LGA1151
The 6-core, 12-thread Xeon E-2276G hits a 4.9GHz boost and 3.8GHz base, with 12MB L3 cache and a PassMark multi-core score of 14089, making it a solid server workhorse. It supports up to 128GB of DDR4 ECC memory at 80W TDP, fitting LGA1151 sockets, which adds flexibility for existing builds. Best for small business owners running virtualization or database workloads who need reliable ECC memory support without high power costs.

Snapshot
The 30-Second Version
A six-core Xeon stuck on a dead socket with DDR4 and ECC. Fine for legacy server upgrades, overpriced for everything else.
Pros & Cons
Pros
- ECC memory support for real server workloads 80th
- Strong single-thread performance with 4.9GHz boost 74th
- Modest 80W TDP keeps power bills sane 68th
- 12 threads handle light virtualization fine 67th
Cons
- Dead-end LGA1151 socket with zero upgrade path
- DDR4 only, no DDR5 support
- Multi-core performance is just average
- Pricing is all over the map and mostly too high
The proof
Performance
The single-thread performance surprised us. 2872 in PassMark single-core puts this Xeon ahead of a lot of newer budget chips, and that 4.9GHz boost is doing real work. But the multi-core story is less exciting. 14089 is solid but unremarkable, and the 12MB of L3 cache feels cramped compared to what AMD is shipping these days. The 80W TDP is efficient for a server part, landing in the 75th percentile for efficiency, but that's because it's only pushing six cores. The gaming score of 34.7 out of 100 tells you everything: this is not a chip for play.

vs Competition
Against the AMD Ryzen 7 9800X3D, this Xeon gets embarrassed. The 9800X3D has more cores, modern DDR5 support, and gaming performance that makes the E-2276G's 34.7 score look like a typo. The HP Xeon 6526Y is a different beast entirely, aimed at higher-end server workloads with more cores and a newer platform. And if you're just looking for cheap server horsepower, the CG CHIPS GATE EPYC part offers way more threads for similar money. The E-2276G only makes sense if you're locked into an existing LGA1151 server board and need a drop-in upgrade.

Price
Value & Pricing
Here's the problem: this chip costs USD 734 in the US, GBP 800 in the UK, and anywhere from EUR 1,030 to EUR 1,827 across European listings. That EUR 797 spread is wild. The best deal we see is at the low end of that EUR range, but even then you're paying a premium for a platform that's been dead for years. Affordability sits in the 9th percentile, which means almost everything else in this category gives you more for your money. Unless you specifically need ECC on LGA1151, this is a tough sell.

Overview
The Intel Xeon E-2276G is a server chip that thinks it's still 2019. Six cores, twelve threads, and a 4.9GHz boost clock sound decent on paper, but this thing is riding on the ancient LGA1151 socket with DDR4 memory. It's a workstation processor for people who need ECC support and don't care that newer platforms exist. The single-thread score of 2872 in PassMark is actually respectable, landing in the 80th percentile, but the multi-core 14089 is just middle of the pack. If you're buying this for a server that needs stability and ECC RAM, fine. If you're buying it for anything else, keep scrolling.
Common Questions
Q: Can I use this Xeon in a regular desktop motherboard?
Only if your board has an LGA1151 socket and supports Xeon E-series chips. Most consumer boards don't, and you'll need a C246 chipset board for full ECC support. Check your motherboard's CPU compatibility list before buying.
Q: Is this good for a home server or NAS?
It'll work, but it's overkill for most NAS setups and underpowered for heavy virtualization. The 80W TDP is nice for 24/7 operation, but you're paying a lot for ECC support you might not need. A used Ryzen or even an older i5 would handle most home server tasks for less.
Q: Does this support DDR5 memory?
No. This chip is DDR4 only, up to 128GB with ECC. If you want DDR5, you need to look at newer Xeon or Ryzen platforms.
Who Should Skip This
If you're building a new server or workstation from scratch, skip this. You're locking yourself into a dead platform with no upgrade path. Go grab a modern Ryzen 7 or a newer Xeon instead. And if you're a gamer, this chip's 34.7 gaming score should send you running to the nearest Ryzen 7 9800X3D listing.
Verdict
The Intel Xeon E-2276G is a niche chip for a niche situation. If you have an LGA1151 server board that needs ECC memory and you can find this at the low end of the price range, it's a reasonable drop-in upgrade. For everyone else, this is outdated hardware at inflated prices. The single-thread performance is the only thing keeping it relevant, and that's not enough to justify the cost in 2025.
