Intel Xeon E3-1245 v6 4-core LGA1151
The integrated Intel HD Graphics P630 on this 14nm Xeon chip enables media transcoding and display support directly from the server without a discrete GPU. Its 4.1GHz boost clock across four cores delivers strong single-threaded responsiveness for its 73W TDP, making it a cost-effective option for entry-level LGA1151 server builds. This processor is best for small businesses running always-on file sharing, media streaming, or lightweight productivity servers where a dedicated graphics card is unnecessary.
Resumo
The 30-Second Version
The Xeon E3-1245 v6 is a four-core server chip with decent single-thread performance and ECC support. It's fine for home servers and NAS builds, but the dead LGA1151 platform and weak multi-core scores hold it back. Worth it at $190, questionable at EUR 330.
Pros & Cons
Prós
- ECC memory support on a cheap LGA1151 board 68th
- Integrated HD Graphics P630 means no GPU needed for headless-ish setups
- 73W TDP keeps power and cooling costs low
- Single-thread performance is well above average for its age
Contras
- Four cores is limiting for modern multi-threaded workloads
- LGA1151 is a dead platform with zero upgrade path
- Gaming performance is disappointing
- Platform score sits near the bottom of our database

Performance
PassMark multi-core of 8658 and single-core of 2382 tells the story. It's snappy for everyday tasks and light server workloads, but four cores is four cores. The 8MB of L3 cache helps, and the 4.1GHz boost keeps single-threaded stuff feeling responsive. But don't expect miracles. Our gaming score of 31.1 out of 100 is a weak spot, and the AI score at 39th percentile lags behind most modern options. For productivity it's solid at 56.5, and server workloads land at 46.9. It's a workhorse, not a racehorse.

vs Competition
Stacked against something like the Ryzen 7 9800X3D, this Xeon gets absolutely demolished. The 9800X3D is a modern gaming and productivity monster, while the E3-1245 v6 is a budget server part from another era. Even against older AMD options like the Phenom II X6, the Xeon wins on single-thread but loses on core count. The be quiet! Dark Rock Pro 5 isn't even a CPU, so that comparison is a bit silly. The real competition here is used enterprise gear. A used Ryzen 5 3600 or even an older Threadripper would crush this in multi-threaded workloads for similar money.

Value & Pricing
Pricing is all over the map depending on where you shop. US listings hover around $190, while European vendors range from EUR 279 to EUR 330. That's a EUR 51 spread, so if you're in the EU, shop around before pulling the trigger. The cheapest EUR listing is the one to grab if you're set on this chip. At $190 it's a reasonable buy for a home server or NAS build. At EUR 330, you're paying too much for 2017 silicon. The value proposition really depends on your local market.

Overview
The Xeon E3-1245 v6 is a server chip from 2017 that's still kicking around on LGA1151. Four cores, 3.7GHz base, 4.1GHz boost, and a 73W TDP. It's basically a Kaby Lake i7 with ECC support and a server badge slapped on it. The HD Graphics P630 iGPU is a nice touch if you need display output without a GPU.
Our database puts this thing firmly in the middle of the pack. Single thread at 67th percentile is decent, multi thread at 57th is fine, but the platform score is rough at 18th percentile. LGA1151 is a dead socket with no upgrade path, and that matters if you're building something today.
Common Questions
Q: Can I use this in a regular desktop motherboard?
Yes, if the board has an LGA1151 socket and supports Xeon E3 v6 chips. Check the motherboard's CPU compatibility list first, since not all consumer boards play nice with Xeons.
Q: Does this CPU support ECC memory?
Yes, ECC support is one of the main reasons to buy this over a consumer i7. You'll need a motherboard that also supports ECC RAM, typically a C236 or C232 chipset board.
Q: Is this good for a Plex server or NAS?
It's a solid choice for that. The 73W TDP keeps power bills reasonable, and the integrated graphics can handle hardware transcoding for Plex. Four cores is enough for a handful of simultaneous streams.
Who Should Skip This
Skip this if you need real multi-threaded performance. Video editors, 3D artists, and anyone running VMs or containers at scale will hit the four-core wall fast. Gamers should absolutely look elsewhere, the gaming score is rough. And if you don't already own an LGA1151 board, buying into a dead platform in 2025 is a tough sell unless the price is right.
Verdict
This chip makes sense for a very specific buyer. You want a cheap home server, a NAS, or a pfSense box with ECC support and low power draw. You don't care about gaming or heavy multi-threaded work. You already have an LGA1151 board lying around or can get one dirt cheap. If that's you, the E3-1245 v6 is a solid pick. If you need anything more than light server duty, look elsewhere.
